Assessment of Factors Associated with Dental Caries in Rural Communities in Rakai District, Uganda
(Clinical Oral Investigations, 2011) Rwenyonyi, Charles Mugisha; Muwazi, Louis Mugambe; Buwembo, William
To assess factors associated with dental caries in rural communities in Rakai District, Uganda. This was a cross-sectional survey in 18–62 year olds, randomly selected from three sub-counties: Kyalurangira (n = 121), Kabira (n = 133), and Kacheera (n = 67). The participants were clinically examined for caries using Decayed Missing Filled Teeth (DMFT) index and were administered to a structured questionnaire. In the whole material, caries prevalence (DMFT score > 0) was 57.3% and the mean DMFT score was 2.3. The M-component contributed 61% of the DMFT scores. Using bivariate analyses, age, consumption of sugared snacks and tobacco smoking were directly and significantly associated with development of dental caries. Tooth cleaning and previous dental visits were indirectly and significantly associated with dental caries. In binary logistic regression analyses, the participants who were older were four times and those who consumed sugared snacks were 11 times more likely to develop dental caries as compared to their counterparts. The participants who cleaned their teeth or who had visited the dentists were less likely to develop dental caries as compared to their counterparts. The odds ratios were 0.6 and 0.5, respectively. Based on stepwise multiple linear regression analyses, age, previous dental treatment, consumption of sugared snacks, tooth cleaning and tobacco smoking explained a total of 46% of the variations in DMFT scores. Caries prevalence and severity were relatively low in this population. Although a number of independent variables were significantly associated with caries they gave a modest overall multivariate model.
Assessment of the Validity and Consequences of Different Methods of Expressing the Severity of Dental Fluorosis in a Subject
(Acta Odontologica Scandinavica, 2000) Rwenyonyi, Charles Mugisha; Birkeland, Jan Magne; Haugejorden, Ola
The aim was to assess the validity and consequences of different methods of expressing severity of dental fluorosis in a subject. The analyses were based on Ugandan children (n = 481), aged 10-14 years, with life-long consumption of drinking water with either 0.5 or 2.5 mg fluoride per liter. Fluorosis was assessed using the Thylstrup and Fejerskov (TF) index. All children (n = 219) with 28 teeth and fluorosis on at least 1 tooth pair were selected to test methods of expressing fluorosis, e.g. the TF score on the most severely affected tooth, a maxillary central incisor, the median and the mean scores. A test group (n = 40), the 10 most and the 10 least severely affected children in each district, was used to evaluate the methods and a reference group (n = 179) to confirm or refute the findings in the test group. To evaluate consequences of the different methods of expressing severity of fluorosis in a subject, children from the low (n = 130) and the high fluoride (n = 132) districts not included in the test or reference group formed the community comparison groups. Comparison between the median (gold standard) and mean scores showed a significant deviation in the reference group only. Most of the partial recording methods, such as the score for the most severely affected tooth, were significantly and systematically higher than the median. While for all recording methods the median score was zero in both communities, the distribution of the subjects according to severity differed significantly between the communities.

(BMC microbiology, 2015) Kityamuwesi, Richard; Muwaz, Louis; Kasangaki, Arabat; Kajumbula, Henry; Rwenyonyi, Charles Mugisha
Predisposing factors of pyogenic odontogenic infection include dental caries, pericoronitis, periodontitis, trauma to the dentition and the supporting structures or complications of dental procedures. The infections are usually polymicrobial involving normal endogenous flora. We characterised pyogenic odontogenic infection in patients attending Mulago Hospital, Uganda.Of the 130 patients, 62 (47.7%) were female. The most frequently involved fascial spaces were: the buccal, 52 (25.4%); submasseteric, 46 (22.4%) and the submandibular space, 36 (17.5%). Dental caries was the most prevalent predisposing factor, particularly of the lower third molar teeth. Viridans Streptococci Group and Staphylococcus aureus were the most frequent bacterial isolates: 23.5% and 19.4%, respectively. All Viridans Streptococci isolates were resistant to penicillin G, sulfamethoxazole/trimethoprim (cotrimoxazole), ampicillin and tetracycline, but susceptible to vancomycin. All Staphylococcus aureus strains were resistant to cotrimoxazole and ampicillin while retaining susceptibility to vancomycin, cefotaxime, linezolid, moxifloxacin and amoxicillin/clavulanate. Thirty five (26.9%) patients were HIV infected and the HIV status did not significantly influence the pattern of odontogenic infection.Dental caries was the most prevalent predisposing factor for pyogenic odontogenic infection. High prevalence of bacterial resistance to ampicillin and cotrimoxazole suggests the need for regular antibiotic susceptibility tests of isolates and rational use of antibiotics in the management of these infections. Prevention requires strengthening of oral health in the community.
A comparison of oral bacteriome isolated from periodontal pockets of participants with or without diabetes mellitus in Uganda: a case control study
(BioMed Central Ltd, 2024-05) Kiryowa, Haruna Muhmood; Buwembo, William; Munabi, Ian Guyton; Mwaka, Erisa Sabakaki; Rwenyonyi, Charles Mugisha; Kaddumukasa, Mark; Kiguli, Sarah
Abstract Objective Diabetes mellitus predisposes patients to increased incidence and severe forms of periodontal disease. Currently, information on the bacterial diversity of patients with diabetes mellitus and periodontitis in Uganda is scanty. This study set out to describe the bacteria associated with periodontitis in patients with diabetes mellitus in Uganda, as part of a larger study describing the association between periodontal disease and diabetes mellitus. Results This was a case control involving 45 samples of gingival crevicular fluid collected from participants with periodontitis, the cases being 26 participants with diabetes mellitus and controls 19 participants without diabetes mellitus. Sequencing using the 16s Oxford nanopore long read protocol was followed by a bioinformatics analysis pipeline for alpha and beta diversity indices in the two groups. Multivariate tests were done to determine the differences in the bacterial composition in the two groups. Of the 739 Operational Taxonomic Units and 500 phyla identified, 37.9% (280/739) were from participants with diabetes mellitus. Analysis of beta diversity revealed a dissimilarity between the two study groups (CAP score=0) with a significant association noted between periodontitis and the subgingival bacteria (P=0.001). Diabetes mellitus reduced the quantity and altered the composition of the subgingival microbiome in the study participants.

Etiology and Pattern of Mandibular Fractures among Patients Attending Oral and Maxillofacial Surgery Unit in Mulago Hospital, Uganda: A Cross–Sectional Study
(Archives of Dentistry and Oral Health, 2018) Mpiima, Patrick; Kasangaki, Arabat; Nkamba, Eriab; Rwenyonyi, Charles Mugisha
The mandible is one of the most commonly fractured bones of the facial skeleton because of its anatomical prominence. The objective of the study was to establish the etiological factors and pattern of mandibular fractures among patients (n=73) aged 3 – 55 years attending the Oral and Maxillofacial Surgery Unit of Mulago Hospital.This was a hospital based cross-sectional study among patients with mandibular fractures who were consecutively recruited after informed consent. The data were collected using a structured questionnaire and clinical oral examination. The collected data were analyzed using Statistical Package for Social Sciences, version 17 for Windows, Chicago, Illinois, USA.There were 73 patients with 107 mandibular fracture sites. Most fractures were caused by road traffic accident (58%) and assault (38%), and especially among pedestrians and passengers. About half of the patients with fractures were aged 21-30 years. The sex ratio of the patients was 7.7 males versus 1 female. About 17% of the patients were under the influence of alcohol during injury. Majority (69.9%) of the injuries occurred in the Kampala Metropolitan area. Single fractures were observed in 55% of the patients and half of them, displaced. About 91% of the patients with multiple fractures were bilateral. The present study indicated that road traffic accidents and assaults were major causes of madibular fractures, particularly among the youths in the studied population. Males were more prone to mandibular fractures.
Oral Manifestations in HIV/AIDSInfected Children
(European journal of dentistry, 2011) Rwenyonyi, Charles Mugisha; Kutesa, Annet; Muwazi, Louis; Okullo, Isaac; Kasangaki, Arabat; Kekitinwa, Addy
To assess factors influencing the distribution of oral manifestations in HIV/AIDS-infected children attending the Paediatric Infectious Disease Clinic in Mulago Hospital, Kampala. This was a cross-sectional study comprising 237 children (males/females: 113/124) aged 1 to 12 years. The parents/guardians were interviewed to obtain demographic information, oral hygiene practices, dietary habits and health seeking behaviours as well as any medications taken. The children were clinically examined for oral lesions based on World Health Organization criteria with modifications. About 71.7% of the children cleaned their teeth. About 16.9% of the children had visited a dentist since birth, mainly for emergency care. One or more oral lesions were recorded in 73% of the children of whom 19.0% experienced discomfort during oral functions. Cervical lymphadenopathy, oral candidiasis and gingivitis were the most common soft tissue oral lesions: 60.8%, 28.3% and 19.0%, respectively. Except for dental caries, the overall frequency distribution of soft tissue oral lesions was significantly lower in children on highly active antiretroviral therapy (HAART) as compared to their counterparts not on HAART. The prevalence of dental caries in deciduous and permanent dentitions was 42.2% and 11.0%, respectively. Tooth brushing and previous visits to the dentist were indirectly and significantly associated with dental caries. About 5.9% (n=14) of the children had <200 CD3 + CD4 T-lymphocyte cells per μl of blood. The majority of the children had one or more oral lesions, particularly in the group not on HAART. Some of the lesions were associated with discomfort during oral functions. (Eur J Dent 2011;5:291-298)

(Odontology, 2013) Nabbanja, Juliet; Gitta, Sheba; Peterson, Stefan; Rwenyonyi, Charles Mugisha
The aim of this study was to assess the orofacial manifestations and their influence on oral function in human immunodeficiency virus (HIV) positive children attending Mildmay Clinic in Uganda. This was a cross-sectional study based on clinical examination, medical records and a structured questionnaire of 368 children aged between 1.5 and 17 years. The clinical examination for dental caries was based on decayed, extracted and filled teeth (deft) and decayed, missing and filled teeth (DMFT) indices as defined by World Health Organisation. The soft tissue orofacial lesions were assessed using the classification and diagnostic criteria as described by the Collaborative Workgroup on the Oral Manifestations of Pediatric HIV Infections. Approximately 67.4% of the children were on highly active antiretroviral therapy (HAART). The majority (77.4%) of the children had at least one orofacial lesion associated with HIV, pseudomembranous candidiasis being the most prevalent. Overall, 61.7% of the children with orofacial lesions reported at least one form of discomfort in the mouth. Discomfort was particularly associated with swallowing. The prevalence of orofacial lesions was significantly higher in children with poor oral hygiene and lower in those on HAART than in their respective counterparts. The CD4+ cell count, age and gender of the children did not significantly influence the distribution of orofacial lesions. The mean deft and DMFT scores were 11.8 and 2.7, respectively. The d- and D-components contributed 54.7 and 42.1%, respectively. Consumption of sugary snacks was directly associated with dental caries. Despite these children attending an HIV care centre of excellence, they have a high prevalence of orofacial manifestations associated with HIV. The majority of the children experienced discomfort in the oral cavity, particularly during swallowing.
Pain Experience and Pain Control among Trauma Patients in Oral and Maxillofacial Surgery Clinic of Mulago Hospital, UgandaPain Experience and Pain Control among Trauma Patients in Oral and Maxillofacial Surgery Clinic of Mulago Hospital, Uganda
(International Journal of Research Studies in Medical and Health Sciences, 2018) Kugonza, Gonzaga; Kasangaki, Arabat; Muwazi, Louis; Rwenyonyi, Charles Mugisha
Pain is an unpleasant sensory and emotional experience often described as tissue damage, in the presence/absence of actual tissue damage or somatic disease. The aim of the present study was to establish pain experience of trauma patients and pain management practices of health care practitioners during invasive interventions in the Oral and Maxillofacial Surgery Clinic of Mulago Hospital. This was a cross sectional study on 187 trauma patients scheduled for invasive interventions who were consecutively recruited. Pain experience was evaluated using a horizontal Visual Analogue Scale to ascertain their pain experience before and during invasive procedures. During surgical invasive procedure, no and mild pain were defined as successful whereas moderate and severe pain were considered failed pain control.Before invasive intervention, 74.3% of the participants reportedly experienced either no or mild pain. During invasive procedures, all participants reported feeling some degree of pain; 21.4% being mild in nature. Overall, there was no consistency in pain control techniques applied for any given intervention with the exception of surgical toilet and zygomatic arch elevation, where anesthetic infiltration was the only technique applied. During surgical toilet, pain control was successful in 84.6% of the participants, while splinting of teeth and intermaxillary fixation, infiltration was successful in 50% and <20% of the participants, respectively. Eyelet wire removal was performed in 40.1% (n=75) of the participants with no form of pain control with 70.6% (n=53) of the participants reporting severe pain during the procedure.Most participants reported a higher degree of pain during the intervention compared to their pre-intervention time. No pain control was provided to patients during eyelet wire removal, most of whom reported severe pain. Most interventions had varied approaches to the pain control techniques with the exception of surgical toilet and elevation of the zygomatic arch.
Prediction of Width of Un-Erupted Incisors, Canines and Premolars in a Ugandan Population:A Cross Sectional Study
(BMC oral health, 2012) Buwembo, William; Kutesa, Annet; Muwazi, Louis; Rwenyonyi, Charles Mugisha
Accurate prediction of the space forms an important part of an orthodontic assessment in the mixed dentition. However the most commonly used methods of space analysis are based on data developed on Caucasian populations. In order to provide more accurate local data we set out to develop a formula for predicting the widths of un-erupted canines and premolars for a Ugandan population and to compare the predicted widths of the teeth from this formula with those obtained from Moyers’ tables, and Tanaka and Johnston’s equations.Dental casts were prepared using mandibular and maxillary arch impressions of 220 children (85 boys/135 girls) aged 12–17 years recruited from schools in Kampala, Uganda. The mesio-distal width of the mandibular incisors, mandibular and maxillary canines and premolars were measured with a pair of digital calipers. Based on regression analysis, predictive equations were derived and the findings were compared with those presented in Moyers’ probability tables, and Tanaka and Johnston’s equations. There were no statistically significant differences between the tooth widths predicted by our equations and those from Moyers’ probability tables at the 65th and 75th percentile probabilities for the girls and at 75th level in boys in the mandibular arch. While in the maxillary arch no statistically significant differences at the 75th and 95th levels were noted in girls. There were statistically significant differences between predicted tooth sizes using equations from the present study and those predicted from the Tanaka and Johnston regression equations.In this Ugandan population, Moyers’ probability tables could be used to predict tooth widths at specific percentile probabilities, but generally, Tanaka and Johnston technique tends to overestimate the tooth widths.

(African Health Sciences, 2015) Kutesa, Annet; Kasangaki, Arabat; Nkamba, Moses; Muwazi, Louis; Okullo, Isaac; Rwenyonyi, Charles Mugisha
The aim was to determine the prevalence and factors associated with dental caries among adults and children in seven districts of Uganda.Participants aged 11-13 (n=1230) and 35-44 years (n=648) were randomly selected from urban and rural areas of Gulu, Soroti, Jinja, Masaka, Kabale, Kabarole and Hoima districts. They were examined by 4 trained and calibrated dentists for dental caries using Decayed, Missing and Filled teeth index as described by World Health Organisation.Overall mean DMFT score was 0.73 for children and 4.71 for adults. Generally, there was a higher mean DMFT score in the rural (2.19) compared to urban areas (1.97). In all the districts, except Hoima, there was a higher mean DMFT score of children in rural compared to urban. In adults, similar trend was mainly registered in Masaka, Hoima and Gulu districts. Most participants (79.9%, n=1309)occasionally ate sugared snacks. Overall, 95% (n=1795) of the participants cleaned their teeth with plastic tooth brushes (71.7%) and chewing sticks (8.3%).Although the severity of dental caries was low, the disease was widespread in the study population. A high proportion of participants reported consumption of sugared snacks and drinks, which calls for oral health education.
Prevalence, Pattern and Perceptions of Cleft Lip and Cleft Palate among Children Born in Two Hospitals in Kisoro District, Uganda
(BMC Oral Health, 2014) Kesande, Teopista; Muwazi, Louis Mugambe; Bataringaya, Aisha; Rwenyonyi, Charles Mugisha
Cleft lip with or without cleft palate is one of the most common congenital anomalies that affect the oro-facial region. The aim of the study was to determine the period prevalence, pattern and perceptions of cleft lip and cleft palate in children born between 2005 and 2010 in two hospitals in Kisoro District, Uganda.The study involved a retrospective review of medical records of mothers who delivered live babies between January 2005 and December 2010 in Kisoro Hospital and St. Francis Hospital, Mutolere in Kisoro District. Key informant interviews of mothers (n = 20) of the children with cleft lip and/or clip palate and selected medical staff (n = 24) of the two hospitals were carried out. The data were analysed using descriptive statistics.Over the 6 year period, 25,985 mothers delivered live babies in Kisoro Hospital (n = 13,199) and St. Francis Hospital, Mutolere (n = 12,786) with 20 babies having oro-facial clefts. The overall period prevalence of the clefts was 0.77/1,000 live births. Sixty percent (n = 12) of children had combined cleft lip and palate and the same proportion had clefts on the left side of the face. More boys were affected than girls: 13 versus 7. About 45% of mothers were hurt on realizing that they had delivered a child with an oro-facial cleft. Forty percent of mothers indicated that a child with oro-facial cleft was regarded as an outcast. About 91.7% (n = 22) of the medical staff reported that these children were not accepted in their communities. Surgical intervention and psychosocial support were the management modalities advocated for by most respondents.The period prevalence of combined cleft lip and palate in two hospitals in Kisoro District was comparable to some findings elsewhere. Cleft lip and cleft palate are a medical and psychosocial problem in Kisoro District that calls for sensitization and counseling of the families and communities of the affected children. The policy makers need to strategically plan for provision of rehabilitation with feeding obturators to facilitate easy feeding to gain weight before surgical intervention of the affected children.

(Brazilian dental journal, 2020) Ndagire, Barbara; Kutesa, Annet; Ssenyonga, Ronald; Kiiza, Harriet Mayanja; Nakanjako, Damalie; Rwenyonyi, Charles Mugisha
Dental caries is one of the most prevalent diseases in developing countries. However, there is limited data on the prevalence and factors associated with dental caries in Ugandan adolescents. The purpose of the present study was to describe the prevalence, severity of dental caries and to determine the factors associated with the disease among school adolescents in Uganda. A cross sectional study was conducted at two secondary schools from Kampala (n=197) and Mukono (n=209) districts, Uganda. At both schools, random sampling was used to select the participating classes and the 406 adolescents (11-19 years) eligible to participate in the research. Dental caries was examined using the Decayed, Missing and Filled Teeth (DMFT) index, and a questionnaire was used to collect other relevant data in form of an oral interview. The data were analyzed using STATA version 12. The data was declared as survey data and all analyses were done with svy command. The prevalence of caries was determined as a percentage of individuals with DMFT score ≥1. Modified Poisson regression models were utilized to assess the association between prevalence, severity of dental caries and independent variables. The overall prevalence of dental caries was 66.0% and mean DMFT score of 2.18±2.67. Dental caries prevalence and severity were significantly (p<0.05) associated with tooth cleaning device, age and history of previous dental visit. There was a high prevalence and severity of dental caries among adolescents, which emphasizes the urgent need to develop and design appropriate interventions to reduce the disease burden.

(Journal Of Dentistry And Oral Implants, 2017) Komakech, Joses O.; Okullo, Isaac; Lakor, Francis; Rwenyonyi, Charles Mugisha
The objective of the study was to establish the role of helmet use on severity and pattern of maxillofacial injuries among motorcycle crash victims attending Mulago Hospital. This was descriptive cross sectional case series study using a questionnaire in form of an oral interview, clinical examination and review of medical records of the pa tients. The pattern of injuries was assessed based on the demarcated regions of the face. The severities of the injuries were scored using the Facial Injury Severity Scale. The data were analysed using SPSS version 17.0. There were 105 participants (male/female: 97/8) aged 15 to 63 years. Most participants (n= 74, 70.5%) were riders and the rest were passengers. There were no female riders. Most participants were from Kampala and surrounding districts. Overall, 35.2% of the participants had helmets: 50% of the riders and 0% of the passengers. About 73% o the participants used Three Quarter Shell helmet design. There was no significant difference in the pattern of injuries between the passengers and non helmeted riders (p=0.076). There was a higher frequency helmeted riders (n = 15, 40.5%) with pan-facial fractures compared to other participants. Non helmeted riders and passen gers had significantly more injuries to the lower two thirds of the face compared to the helmeted riders. Passen gers had less severe facial injuries compared to riders. We conclude that about a third of the participants who were riders used helmets, being particularly the Three Quarter Shell design. The helmeted riders had more severe maxillofacial injuries and of panfacial category as compared to other participants. The passengers had least severe injuries compared to riders. It is recommended to carry out further studies to elucidate on motorcycle related max illofacial injuries especially in regard to the quality of helmets and their adequate use
Root and Canal Morphology of Maxillary First Premolar Teeth in a Ugandan Population
(Open J Stomatol, 2011) Rwenyonyi, Charles Mugisha; Kutesa, Annet; Muwazi, Louis; Buwembo, William
To determine the variations in the root and canal morphology of the maxillary first premolar teeth in a Ugandan population. Extracted maxillary first premolar teeth (n = 202) were evaluated in this study. The specimens had their pulp chambers de-roofed. They were decalcified in nitric acid and made transparent with methyl salicylate. Indian ink was injected into the root canals to display their configuration. Results : One hundred and forty eight (73.3%) of the specimens had two roots, of which 16.9% (n =25) had fused roots. About 26.7% (n = 54) of the specimens were single rooted. Eleven (20.4%) of the single rooted specimens had one canal of either Vertucci type I, III, V or VII configuration while 79.6% (n = 43) of the specimens had two canals of either Vertucci type II, IV or VI configuration. The two-rooted specimens exhibited Vertucci type IV and VIII canal configuration: 96.6% and 3.4%, respectively. The single rooted teeth had a higher prevalence of lateral canals, canal intercommunications and multiple apical foramina as compared to the two-rooted specimens. Conclusion : The maxillary first premolar teeth in this Ugandan population showed a higher prevalence of two-root morphology with majority of the roots having Vertucci type IV canal configuration. There was no three-root anomaly recorded in the present material.
Variation in Caries Experience and Sugar Intake among Secondary School Students in Urban and Rural Uganda
(Acta Odontologica Scandinavica, 2003) Okullo, Isaac; Åstrøm, Anne Nordrehaug; Haugejorden, Ola; Rwenyonyi, Charles Mugisha
The objective was to assess the socio-demographic variation in caries experience and sugar intake among urban (Kampala) and rural (Lira) students in Uganda. In a cross-sectional survey, a total of 1146 adolescents aged between 13 and 19 years (response rate 87%) attending 10 secondary schools, 5 rural and 5 urban, completed questionnaires in respective schools. Clinical examination was conducted among 372 respondents (response rate 90%) from the main survey and dental caries was assessed. The results showed that a total of 80% of the students had DMFT >0. The corresponding rates in Kampala and Lira were 85% and 76% (P < 0.05), respectively. The mean DMFT, DT, and MT for the sample were 2.9, 2.5, and 0.5. Adjusted mean DMFT scores were 2.4 in Kampala and 3.3 in Lira (P < 0.05). The mean frequency sugar score was 2.6 and sugar consumption was higher in females and in students of highly educated parents compared to their counterparts in the opposite groups. In conclusion, higher mean DMFT scores in urban than in rural areas are often reported from developing countries but this does not seem to apply to the Ugandan areas investigated. Kampala and Lira students were equally exposed to sweets and soft drinks but the differences in sugar consumption between students of higher and lower educated parents were most marked in Lira.
Weight, Height and Eruption Times of Permanent Teeth of Children Aged 4–15 Years in Kampala, Uganda
(BMC oral health, 2013) Kutesa, Annet; Nkamba, Eriab Moses; Muwazi, Louis; Buwembo, William; Rwenyonyi, Charles Mugisha
Tooth eruption is a continuous biological process by which developing teeth emerge through the jaws and the overlying mucosa to enter into the oral cavity. Tooth eruption time and sequence are important factors in dental treatment planning, particularly in orthodontics, but also in forensic dentistry to estimate age of a child. Tooth eruption time is influenced by many factors. In this study we set out to determine the timing of eruption of permanent teeth and assess its association with the height and weight of school children aged 4–15 years in Kampala, Uganda.This was a cross sectional study comprising of 1041 healthy Ugandan children: boys/girls (520/521) who were consecutively selected from two primary schools in Kampala. The children were clinically assessed for tooth emergency through the oral mucosa as well as measuring their weight and height. The mean and standard deviation of tooth eruption time was estimated for boys and girls. Bivariate analysis was used to assess any significant association between tooth eruption time and demographic variables. Pearson and partial correlation analyses were used to assess any significant association between the tooth eruption time and anthropometric measurements of the children.Generally, the mean eruption times for girls were lower compared to boys except for three teeth (#25, #32 and #42) which erupted earlier in boys. The average difference in mean eruption times of all teeth between boys and girls was found to be 0.8 (range, 0–1.5) years. In partial correlation analysis, mean tooth eruption times were positively, but not significantly associated with height while controlling for weight except for the mandibular left central incisor (#31). On the other hand, in partial correlation analysis, mean tooth eruption times were positively associated with weight while controlling for height except for tooth #11, #16, #26 and #41. The weight of the child was significantly correlated with mean eruption times in 50% of the teeth.In the present study, the mean tooth eruption times for girls were lower compared to boys except for three teeth (#25, #32 and #42). The height of the child did not show any significant influence on the tooth eruption times while the influence of weight on tooth eruption times was non-conclusive.
