Assessment of the knowledge, attitude and practices of the informed consent process in oral healthcare among dental students in Makerere University Dental Hospital, Uganda.

INTRODUCTION: Informed consent is an ethical and legal component of healthcare. It ensures patient autonomy and allows patients to make decisions regarding their treatment. In dental care, informed consent is particularly important because most dental procedures are invasive. Since dental students are future dentists, they need to learn about their ethical obligations and accountability through the informed consent process as this is critical to patients' well-being. This study aimed to determine dental students' knowledge, attitudes, and practices of the informed consent process for oral health care in Makerere University Dental Hospital, Uganda. STUDY METHODOLOGY: This was a descriptive cross-sectional study using quantitative methods. It was carried out at Makerere University Dental Hospital and third, fourth, and fifth-year students (n = 102) pursuing a Bachelor of Dental Surgery program took part in the survey. A self-administered structured questionnaire was used to assess their knowledge, attitudes, and practices of informed consent for oral health care. Collected data were entered into Epi-data version 3.1, where it was cleaned, coded, and imported to STATA version 14 software for statistical analysis. RESULTS: About two-thirds 67 (65.7%) of the participants were males. The mean age was 25 (SD = 3.21) years. The majority (90%) of the students had a high level of knowledge of the informed consent process. About (80%) had a positive attitude towards informed consent and (85%) most often practiced the informed consent process. Based on bi-variate analysis, training on informed consent, year of study, age, and sex were significantly associated with the informed consent process. However, there was no significant risk factor associated with informed consent in multiple logistic regression analysis. CONCLUSION: The study findings highlighted high levels of knowledge, positive attitude, and practice of the informed consent process among the clinical dental students. Continuous training is necessary to remind dental students about the importance of informed consent in healthcare, not only for complex procedures.

Exploring lived experiences on the usage of removable complete dentures among edentulous patients attending Makerere University Dental Hospital, Kampala, Uganda.

BACKGROUND: Edentulism remains a major disability worldwide, especially among the elderly population, although the prevalence of complete edentulism has declined over the last decades. In Uganda, the prevalence of edentulism in people aged 20 years and above is 1.8%. The therapy for edentulous patients can be realized through the use of conventional removable complete dentures, implant-supported prostheses, and computer-aided design and computer-aided manufacturing (CADCAM), however, the provision of removable complete dentures continues to be the predominant rehabilitation for edentulous patients. However, no published study has explored the lived experiences with removable complete dentures among the Ugandan population. The aim of the present study was to explore patients' lived experiences on the usage of removable complete dentures among Ugandan edentulous patients attending Makerere University Dental Hospital. METHODS: This was a qualitative study approach using purposive sampling. Fifteen (15) respondents were selected across social demographics. Interviews were recorded and transcribed and themes were generated to draw a deeper meaning to the usage of removable complete dentures. A qualitative statistical package, Atlas Ti software was used to generate themes from the interviews followed by an interpretation of the generated data and the results were presented as text and in a table. RESULTS: The reported key positive experiences due to removable complete denture rehabilitation were the improvement in speech, eating ability, regaining good facial appearance, better oral hygiene management, self-esteem and confidence to smile in public, and a feeling of completeness. However, respondents complained of pain and discomfort due to the looseness of dentures, inability to eat certain foods, and regular cleaning of dentures. The respondents did not go through proper informed consent processes before getting removable complete dentures. CONCLUSION: The study found that patients were satisfied with their removable complete dentures rehabilitation due to the positive experiences registered, such as the ability to eat and talk well, and restoration of self-esteem, all of which improved their quality of life. However, they experience pain and discomfort due to the looseness of dentures.

Dentists' perspectives, practices, and factors associated with informed consent process for fixed prosthodontic treatment: a cross-sectional study of kampala metropolitan area, Uganda.

BACKGROUND: Dentists have a legal and ethical obligation to obtain informed consent from patients before carrying out treatment. In Uganda, the process of obtaining informed consent in dentistry is not well documented. The aim of the present study was to determine dentists' perspectives and practices regarding informed consent to fixed prosthodontic treatment (FPT) in Kampala Metropolitan, Uganda. METHODS: A quantitative cross-sectional study was conducted among 153 dentists from July to September 2023. Data were collected using a semi-structured self-administered questionnaire that included both closed- and open-ended questions. The questionnaire included items on participants' sociodemographic information, perspectives, and practices about informed consent for FPT. Perspectives were rated using ten items on a five-point Likert scale. The minimum possible total score was 10, and the maximum possible score was 50. Descriptive statistics and Poisson regression were used to summarize and analyze the quantitative data, and the significance level was set at p < 0.05. Open-ended items were analyzed using content analysis. RESULTS: The majority (83.9%) of the participants were general dentists with working experience ranging from 1 to 38 years and a median of 8 years. The majority were familiar with the concept of informed consent and had positive perspectives regarding its use for FPT. The mean score for perspectives was 39.27 (SD, 5.42). However, there were variations in the practices of the dentists. More than three-quarters (87.6%) reported that they always obtained the patient's informed consent before FPT. Less than a third (29.4%) obtained written consent for FPT. About half of the dentists provided information regarding the procedure, benefits, and risks of treatment during the consent process. Bivariate analysis showed that the use of written consent for FPT was significantly (p < 0.05) associated with having a work experience of more than 10 years and having had training involving informed consent after undergraduate studies. CONCLUSION: The present study provides baseline data regarding perspectives and practices regarding informed consent for FPT among dentists in Uganda. It is recommended that regular training courses be developed to highlight the importance of improved informed consent practices for patient protection and to instruct dentists about obtaining valid informed consent. There is a need for future research to streamline guidelines for the informed consent process in dental care in Uganda.

Assessment of the informed consent process in the provision of dental care in Mulago hospital, Uganda.

BACKGROUND: Informed consent is grounded in the principle of autonomy and represents patients' right to participate in clinical decisions regarding their treatment. It is equally an ethical and legal requirement in dental care. The dental practitioner must offer appropriate information about all aspects of the treatment and ensure that a patient understands and makes an informed decision. There is limited literature on informed consent for dental care in Uganda. This study assessed patients' comprehension of the informed consent process and dental practitioners' practices in obtaining informed consent. METHODS: This was a cross-sectional descriptive study conducted in the Dental Outpatient Department of Mulago Hospital. Two separate questionnaires were employed to collect data from dental patients and dental practitioners, respectively. Data were entered into Epi-data, coded, and imported into STATA 14 for statistical analysis. RESULTS: Overall, the level of patients' comprehension of the informed consent process was 91.1%, with 96.3% who felt the dental practitioners satisfactorily explained to them the treatment received and, 65.1% understood very well the information given to them. About 93.5% of the patients confessed that they were given other options of treatment while 98.5% consented before the dental practitioners started treatment. Most dental practitioners 94.7% followed good clinical practices in obtaining informed consent and 98.7% gave information before initiation of treatment while 85.3% obtained consent from patients before starting any procedures. However, only 5.3% of the dental practitioners obtained written informed consent from patients. CONCLUSION: There is a need to devise ways of improving patients' understanding of the treatment information given to them to support them make better and informed decisions regarding their care. Dental practitioners need to put more emphasis on the use of written consent in dental care because documentation helps in providing accountability and protects dentists from medical litigation in case the patients were to sue them for any treatment-related complications.

Dental Practitioners' Knowledge, Attitude, and Practice in Caries Risk Assessment and Management: A Cross-sectional Survey in Kampala Metropolitan, Uganda.

AIM: The objective of this study was to determine the knowledge, attitude, and practices regarding caries risk assessment (CRA) and management among dental practitioners in Kampala Metropolitan, Uganda. MATERIALS AND METHODS: This cross-sectional study was conducted among 270 dental practitioners in Kampala Metropolitan, Uganda, in May 2021. The participants were dental surgeons and public health dental officers. A self-administered structured questionnaire was used to collect data. The questionnaire included items about participants' sociodemographic characteristics, knowledge, attitude, and practices in CRA and management. Attitude and practices were rated using different Likert scales. Descriptive statistics, Chi-square/Fisher's exact and one-way analysis of variance (ANOVA) with post-hoc Bonferroni tests were used to analyze the data. The significance level was set at p <0.05. RESULTS: About 60.7% of the participants were public health dental officers with a median age of 30 years (interquartile range [IQR], 27-60). Overall, the participants were familiar with the current concepts regarding CRA and management. More than 70% of the participants correctly identified risk factors and indicators of dental caries. Most participants (98.5%) had a positive attitude toward performing CRA. However, their practices regarding caries management were inadequate as majority (>75%) of participants reported that they never or occasionally recommended evidence-based products like topical fluoride, probiotics, or xylitol products in the prevention and management of dental caries. Dental surgeons had significantly better knowledge and practices than public health dental officers (p <0.05). CONCLUSION: In the present study, the participants were familiar with the current concepts about CRA and had a positive attitude toward CRA. However, their practices regarding caries prevention and management were inadequate. CLINICAL SIGNIFICANCE: The study provided baseline data about knowledge, attitude, and practices regarding CRA and caries management among dental practitioners in Uganda. It is recommended to design training courses in evidence-based protocols in the prevention and management of dental caries for dental practitioners in Uganda.

Characteristics of pyogenic odontogenic infection in patients attending Mulago Hospital, Uganda: a cross-sectional study.

BACKGROUND: 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. RESULTS: 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. CONCLUSIONS: 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.

Prevalence, pattern and perceptions of cleft lip and cleft palate among children born in two hospitals in Kisoro District, Uganda.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION/RECOMMENDATIONS: 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.

Periodontal conditions, low birth weight and preterm birth among postpartum mothers in two tertiary health facilities in Uganda.

BACKGROUND: Literature reports have indicated an increase in research evidence suggesting association between periodontal disease and the risk of pre-term birth (PTB) and low birth weight (LBW). Periodontal diseases in Uganda have been documented as a public health problem, but their association to adverse pregnancy outcomes is unknown. This study was conducted to assess the association between periodontital diseases in postpartum mothers and PTB and LBW of babies in Mulago and Mbarara referral hospitals. METHODS: This was a cross sectional study using medical records, clinical examination and oral interview of mothers at the two tertiary health facilities. Mothers with singleton babies from Mulago (n = 300) and Mbarara Hospital (n = 100) were recruited for the study. The women were clinically examined for periodontal disease by 2 trained and calibrated dentists. Data on PTB and LBW were retrieved from medical records. The data were analyzed to determine the relationship between the four parameters for periodontal disease (bleeding gingiva, periodontal pockets, gingival recession and calculus with plaque deposits) and the adverse pregnancy outcomes. Frequency distribution was used to describe the data. Bivariate and multivariate analyses were used to study the association between the periodontal diseases and adverse pregnancy outcomes. RESULTS: Approximately 26% and 29% of the postpartum mothers examined had bleeding gingiva and periodontal pockets of 4 mm or more deep, respectively. Advanced periodontitis i.e. pocket depth ≥ 6 mm was recorded in 13 (3.6%) of the mothers. Calculus with plaque deposits were recorded in 86% (n = 343) of the mothers. Gingival recession was recorded in 9.0% of the mothers and significantly and directly related to birth weight (p < 0.05). CONCLUSION: Periodontal conditions of postpartum mothers in this study were found to be better than previously reported amongst the Ugandan population. Bivariate analysis showed a significant association only between gingival recession and low birth weight. However, this finding should be interpreted with caution as it could have occurred by chance.

A comparison of oral bacteriome isolated from periodontal pockets of participants with or without diabetes mellitus in Uganda: a case control study.

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.

Orofacial manifestations in HIV positive children attending Mildmay Clinic in Uganda.

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.

Weight, height and eruption times of permanent teeth of children aged 4-15 years in Kampala, Uganda.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Patient-reported oral mucositis in solid tumour patients undergoing chemotherapy: a Ugandan experience.

Purpose: The mitotic rate of the gastrointestinal tract (GIT) mucosa predisposes the entire system to chemotherapeutic-induced mucositis but the oral cavity due to its accessibility provides an opening to evaluate the extent of the problem much more easily. In addition, the oral cavity being the gateway to the GIT affects the feeding ability of the patient when the ulcers set in.It is therefore from this perspective that we embarked on a study to evaluate the extent of mucositis among patients being treated for solid tumours at our centre. Methods: Using the mouth and throat soreness (OMDQ MTS) questionnaire, we prospectively evaluated mucositis among 100 patients undergoing chemotherapy for solid tumours at the Uganda Cancer Institute. In addition to patient reported outcomes, we also had clinician assessed mucositis measurements. Results: Approximately, 50% of the participants were breast cancer patients. The results demonstrated that patient assessment of mucositis is possible in our setting at a 76% full compliance rate. Up to 30% of our patients reported moderate-to-severe mucositis, though the figure was lower as assessed by the clinicians. Conclusions: The self-reported OMDQ MTS can be useful in our setting for daily mucositis evaluation, hence leading to timely hospital visits before the manifestation of severe complications.

A Quasi-experimental Study Evaluating the Effectiveness of Cryotherapy on Chemotherapy-induced Oral Mucositis Prevention at the Uganda Cancer Institute.

INTRODUCTION: Low-cost interventions such as cryotherapy are not routinely practiced in sub-Saharan Africa to prevent chemotherapeutic-induced oral mucositis. We investigated the feasibility and effect of cryotherapy on oral mucositis at the Uganda Cancer Institute. METHODS: This was a quasi-experimental nonequivalent research study design. We had two groups with each group meant to have 100 participants. We analyzed based on participants who underwent the protocol procedures. RESULTS: Only cancer types were significantly different between the control and intervention groups (χ2=31.09, df =18, p=.030). Twenty percent (n=19) out of the 95, while 8.2% (n=7) out of the 85 in the control and intervention groups respectively developed moderate to severe mucositis (Mantel-Cox and Generalized Wilcoxon p= .026 and p=.031, respectively). CONCLUSION: The use of cryotherapy in our local setting and many sub-Saharan African countries is feasible and affordable to prevent and control chemotherapy-induced oral mucositis.

Periodontitis is associated with insulin resistance in adults living with diabetes mellitus in Uganda: a cross- sectional study.

INTRODUCTION: Evidence suggests that majority of patients with diabetes mellitus in Uganda have poor glycaemic control as well as periodontal disease. This study set out to determine the association between periodontitis and insulin resistance in adult patients with diabetes mellitus in Uganda using the triglyceride glucose index. METHODS: Two hundred and twenty-three adult study participants with confirmed diabetes mellitus were enrolled in a cross-sectional study. Oral examination was carried with the aid of a periodontal probe to determine the periodontal status and findings recorded using the WHO Oral Health Assessment Tool for Adults, 2013. We recorded clinical details for body mass index (BMI in kg/m2) and laboratory parameters including fasting blood sugar (mmol/L), glycated hemoglobin levels (HbA1c, %) and serum triglycerides (mmol/L) using a study questionnaire. Data were analyzed using R version 4.10. The glucose triglyceride index was used as a measure of insulin resistance. Logistic regression analysis carried out to determine the factors associated insulin resistance. RESULTS: The majority of the study participants was female (70%) with an average age of 48.5 years (SD+/- 11.1). The mean body mass index was 29.6 kg/m2 (SD+/- 5.82). The mean serum triglyceride index was 9.48 (SD+/- 0.675). Eighty-six-point 1% of the participants had periodontal disease. Bivariate analysis revealed high odds for male sex (OR = 1.31, 95% C.I = 0.44-4.84, p = 0.65) and periodontitis (OR = 3.65, 95% C.I = 0.79-26.15, p = 0.13) but low odds for a high BMI (OR = 0.45. 95% C.I = 0.07-1.67, p = 0.30). Multivariate regression revealed a significant association between insulin resistance and periodontitis. (AOR = 3.52, 95% C.I = 1.19-1.83, p = 0.03). CONCLUSION: Insulin resistance is highly prevalent in patients with diabetes mellitus in Uganda and is associated with periodontitis and low body weight.

Prediction of width of un-erupted incisors, canines and premolars in a Ugandan population: a cross sectional study.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Prevalence and factors associated with periodontal disease in patients with diabetes mellitus attending Kiruddu National Referral Hospital, Uganda.

Introduction: patients with diabetes mellitus present with high rates of periodontal disease. Severity and extent of periodontal disease may be directly associated with poor glycemic control. The burden of periodontal disease in patients with diabetes mellitus in Uganda is not documented. This study set out to determine the prevalence and factors associated with periodontal disease in patients with diabetes mellitus attending a national referral hospital in Uganda. Methods: this was a cross-sectional study involving 264 patients with diabetes mellitus. Data were collected using a pretested questionnaire to assess factors associated with periodontal disease. This was followed by an oral examination to determine the community periodontal index (CPI) and clinical attachment loss (CAL). Laboratory tests included glycated hemoglobin and fasting blood sugar. Factors associated with periodontal diseases were evaluated using logistic regression analysis. Results: of the 264 participants, 68.9% were females. The average age was 48.9 (SD = 11.0) years. Majority of the participants (32.6%) had diabetes mellitus for 2 to 5 years with oral hypoglycemic drugs being the most commonly (55.7%) used medication. The overall prevalence of periodontal disease was 85%. Univariate analysis revealed that prevalence of periodontal disease was associated with male sex, lower level of education, smoking, oral hygiene practices, poor glycemic control and combined diabetic medication. However, based on multivariate model, this prevalence was only significantly associated with lower level of education: aOR: 10.77 95% CI 1.04-226.38, p=0.05. Conclusion: periodontal disease is highly prevalent in patients with diabetes mellitus in Uganda, especially those with a lower level of education. All diabetic patients should be screened and managed for periodontal disease. Oral health interventions should also be packaged and presented in a simple language to allow easy comprehension by even the less educated population.

Assessment of factors associated with dental caries in rural communities in Rakai District, Uganda.

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.

Prevalence, Severity and Factors Associated with Dental Caries Among School Adolescents in Uganda: A Cross-Sectional Study.

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.

Dental age estimation using radiographic assessment of third molar eruption among 10-20-year-old Ugandan population.

AIM: This study aimed at establishing the age for third molar eruption among Ugandans aged 10-20 years. MATERIALS AND METHODS: This was a cross-sectional study comprising 471 male and 541 female patients attending Mulago Dental Clinic. Patients' orthopantomographs were assessed for third molar eruption as described by Olze et al. Age was summarized using means/SD. Jaw and sex differences were assessed using Student's t-test. RESULTS: Complete eruption (Stage D) ranged between 13 and 20 years. The mean age at complete eruption for girls and boys was 17.5-18 years and 18.2-18.6 years, respectively. Mean age was statistically significantly (P < 0.05) lower among girls compared to boys for all third molar teeth (#18, #28, #38, and #48). The difference in mean eruption times between girls and boys was -0.62 (95% confidence interval: 0.2-1.0, P = 0.006). At 18 years, 40% or 41% maxillary and 52% or 53% mandibular molars were completely erupted. There were statistically significant differences in eruption between the sexes and jaws for all teeth (P < 0.05). CONCLUSIONS: Given the fact that the percentage of erupted third molars by age 18 was found to be <50% on an average in this Ugandan population, we should reconsider the use of third molar eruption as a definitive tool for age estimation in this population.

Socioeconomic and nutritional factors associated with age of eruption of third molar tooth among Ugandan adolescents.

This study aimed to establish the influence of socioeconomic and nutritional factors on the age of eruption of the mandibular third molar among Ugandans aged 10-20 years. MATERIALS AND METHODS: This was a cross-sectional study carried out in a dental clinic of Mulago Hospital between January and December 2017. The background information was obtained from the participants using a questionnaire in the form of an oral interview. The anthropometric measurements were obtained using a tape measure and a weighing scale, while dental radiographs were used to determine the eruption stages of the mandibular third molar. STATISTICAL ANALYSIS: The data were analyzed using STATA 13 and summarized using descriptive statistics and multivariate analyses. Statistical significance was inferred at P < 0.05. RESULTS: Participants in the overweight body mass index category were statistically significantly associated with the age of the mandibular third molar eruption (P < 0.05) compared to their normal counterparts. There was no statistically significant association between socioeconomic status and age of eruption of third molar teeth (P > 0.05). Age of eruption was statistically significantly higher among males than females (P > 0.05). CONCLUSION: The findings of the present study reveal that overweight influences early eruption of the mandibular third molar tooth, although there is no trend between socioeconomic status and the age of eruption of the mandibular third molar.
