    Etiology and Pattern of Mandibular Fractures Among Patients Attending Oral and Maxillofacial Surgery Unit in Mulago Hospital, Uganda: a Cross–Sectional Study
    (SRYAHWA, 2018) Rwenyonyi, Charles Mugisha; Mpiima, Patrick; Kasangaki, Arabat; Nkamba, Eriab
    Background: The mandible is one of the most commonly fractured bones of the facial skeleton because of its anatomical prominence. Objective: 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. Methods: 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. Results: 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. Conclusions: 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.

    Prevalence and Factors Associated with Dental Caries Among Children and Adults in Selected Districts in Uganda
    (African Health Sciences, 2015-12) Kutesa, Annet; Kasangaki, Arabat; Nkamba, Moses; Muwazi, Louis; Okullo, Isaac; Rwenyonyi, Charles Mugisha
    Objective: The aim was to determine the prevalence and factors associated with dental caries among adults and children in seven districts of Uganda. Methods: 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. Results: 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 dis tricts. 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%). Conclusion: 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.

    Seasonality of Burkitt's lymphoma in Uganda
    (Indian Association of Oral and Maxillofacial Pathology, 2014-09) Muwazi, Louis; Rwenyonyi, Charles Mugisha; Kutesa, Annet; Kasangaki, Arabat; Kamulegeya, Adriane
    Background/Aims: Burkitt’s lymphoma is the most common childhood oral maxillofacial tumor in Africa and some studies have reported seasonal variation. Materials and Methods: All Burkitt’s cases diagnosed from 1969 to 2006, from all over Uganda, at the Makerere University’s Department of Pathology, were analyzed, to determine seasonal variation. This was done by evaluation of monthly and rainy versus dry season prevalence. Statistical analysis: The Wilcoxon test was used in both cases, to assess the statistical significance of differences in the diagnostic rates of Burkitt’s lymphoma, in comparison to nonspecific chronic inflammation, using the total as the denominator. Yearly variation in prevalence was examined by a Chi‑square test for linear trend. Mann‑Whitney tests were done to compare the climatic regions. Multivariate analysis of variance (MANOVA) was used to test for differences when gender, seasons and climatic regions were factored in. Results: Although monthly frequencies varied considerably over the period, none of the differences were statistically significant (Pearson’s 15.199, degrees of freedom df = 11, P = 0.174). Likewise, there was no statistically significant difference in the total number of Burkitt’s and nonspecific chronic inflammation biopsies handled at the Department during the rainy and dry seasons. Conclusion: Although the 38‑year period gave us sufficient numbers to use the Edward’s method for seasonality, it also meant that a lot of seasonal changes that occurred during the period were not taken into consideration. We hence feel that a review of this data with weather experts, so as to group the biopsies into accurate rainfall and dry patterns, would yield a more authoritative publication.
