Item Caregiver's oral health knowledge, attitudes and practices towards children with special health care needs in Harare Province, Zimbabwe(University of the Witwatersrand, Johannesburg, 2023-11) Mashanda, Vimbai; Tootla, Saidah; Malauy, CathrineBackground: Children with Special Health Care Needs (CSHCN) are prone to oral diseases such as dental caries and periodontal disease. This is due to limitations in oral hygiene practices because of their debilitating conditions. Therefore, caregivers play a major role in the maintenance of CSHCN’s oral health. As a result, caregiver’s oral health knowledge and attitudes are important to ensure that the oral health of CSHCN is maintained. Aim and Objectives: The aim of this study was to describe the caregiver’s oral health knowledge, attitudes, and practices (KAP) towards CSHCN. The objectives of the study were to determine the caregiver’s demographic profile, to assess the caregiver’s oral health KAP towards CSHCN and to assess whether there is a relationship between the caregiver’s level of education, demographic characteristics, and oral health KAP and factors related to oral health practices. Methods: A quantitative cross-sectional study design and convenience sampling method was utilised. Caregivers above 18 years of CSHCN who attended support group meetings in Harare Province, Zimbabwe and were willing to participate, took part in the study. A modified self-administered questionnaire (SAQ) was used for data collection. The SAQ comprised of a demographics section for the caregiver, child’s disability type and oral health KAP questions. Two sample t-tests and Analysis of Variance (ANOVA) was used to compare the means of caregivers KAP. Multiple linear regression model was used to assess the association between caregivers’ KAP and demographic characteristics. Only the variables with p<0.15 in the univariate model were included in the multiple linear and multivariate logistic regression models. Multivariable logistic regression was used to assess the association between caregivers’ oral health practice and demographic characteristics. Apriori variables such as age, level of education, knowledge and attitude were selected for all multivariable logistic models. All variables with p<0.05 were considered to be statistically significant and statistical analysis were performed using Stata. Results: The response rate was 76.8% n=295). Almost 90% (89.2%, n=263) of the caregivers were females and nearly three quarters (72.5%, n=214) were mothers. A third (33.6%, n=99) of the caregivers were aged between 31-40 years. Fifty-three percent (n=157) of the caregivers were unemployed and 61.7% (n=182) were educated up to high school level. Forty-six percent (n=135) of the CSHCN had cerebral palsy. Out of the 295 caregivers, 45.4% (n=134) had fair oral health knowledge, 79.7% (n=235) had a good attitude towards oral health and 62% (n=183) had fair oral health practices. Conclusions: Most of the caregivers had good oral health attitude, however their knowledge and practices were fair. Factors associated with caregivers’ attitude were their knowledge and level of education, and the caregivers’ practices were associated with knowledge and attitude.Item Factors associated with delayed presentation among patients with oral cancer in Malawi central hospitals(University of the Witwatersrand, Johannesburg, 2023-10) Lungu, Nathan; Sekhoto, M.G.; Turton, M.Background: Oral cancer patients are prone to delays in visiting healthcare facilities resulting in delayed diagnosis, poor prognosis, disfigurement of patients, and increase in management costs. Objective: The aim was to assess factors related to health-seeking delay among patients with oral cancer in Malawi's central hospitals. Methodology: This research was a descriptive cross-sectional study of patients with oral cancer. The study was conducted in all Malawi referral hospitals' dental clinics from April to June 2023 using a closed-ended, structured questionnaire. Results: Thirty-six (52.94%) patients visited the hospital when in pain, and 66.18% (n=45) were not aware of oral cancer. A significant, statistical relationship (p=0.042) was identified between the delay and reporting to the nearest health care facility. Conclusion: Lack of awareness, pain and distance to the nearest health care facility were associated with delays. Education and awareness in primary health care can help prevent treatment delays.Item A retrospective study of histologically diagnosed intra-oral lesions within Ugu district, KZN, South Africa(University of the Witwatersrand, Johannesburg, 2023-10) Reddy, Larisha Yashoda; Premviyasa, VinayagieIntroduction: The oral cavity is exposed to a magnitude of physical and chemical trauma, carcinogenic agents and microbial pathogens that may cause a wide spectrum of oral lesions. These oral lesions may appear as benign, potentially malignant, or malignant thereby requiring biopsies to determine histopathological features to confirm a diagnosis. Oral lesions have the potential to hinder the quality of life for the afflicted patient. The patients’ speech, mastication, swallowing may be affected with the occurrence of oral dysesthesia. With the confirmation of a positive malignant biopsy, the afflicted individual will have to endure the possible side effects of chemotherapy and radiation. In global studies, the prevalence of oral lesions may vary amongst different countries, geographical areas, ethnicities, cultural practices, and social habits. Aim: To identify the different types of intra-oral lesions and the prevalence of malignant oral lesions within UGU district, Kwa- Zulu Natal (KZN). Objectives: 1. To identify the different types of intra oral lesions and characterise by demographics. 2. To determine the prevalence of malignant oral lesions within UGU district, KZN. 3. To determine the association between patients’ social habits and the development of the most common intra oral lesions, with the differentiation of malignant vs non-malignant oral lesions. 4. To assess the concordance of a clinical differential diagnosis and histopathological diagnosis. Study design and Methodology: A quantitative, retrospective case review of dental patient files and histopathological reports of the four selected hospitals in UGU were analysed from January 2016 to August 2022. One hundred and thirty-four patient records were reviewed. Data collected included patients’ age, gender, comorbidities, social habits, differential diagnosis, and histological diagnosis. The data was analysed using a free open-source statistical software program called “R”. Study results: One hundred and thirty-four patients met the criteria of this study. The age of patients ranged between seven and eighty-seven (M= 46.37; SD= 20.77). There were 81 females (60.4%) and 53 males (39.6%). Benign lesions had represented 67.2% (N: 90) of the intra oral biopsies, with the remaining 32.8 %, (N:44), representing malignant lesions. The most common lesions presenting in UGU district were fibrous epulis (N: 15, 11.2%), pyogenic granuloma (N:36, 26.9%) and squamous cell carcinoma (N:37, 27.6%). No statistical relation was proven between ethnicity, sex, and social habits with the benign lesions of fibrous epulis and pyogenic granuloma. Statistical relation was proven between squamous cell carcinoma and ethnicity, gender, and social habits. A substantial level of concordance (agreement) was proven with the Kappa Statistic of 0.7437, hereby indicating a good general knowledge of intra-oral lesions amongst the dentist performing the intra oral biopsies within UGU district. Conclusion: Fibrous epulis, pyogenic granuloma and oral squamous cell carcinoma had been identified as the three most common lesions in UGU, KZN, representing 65.7% of the confirmed biopsy results. Fibrous epulis and pyogenic granuloma had shown no statistical association to ethnicity, gender, alcohol consumption and smoking. In this study, oral squamous cell carcinoma had shown statistical association to white males and consumption of alcohol and smoking. This study has demonstrated the diversity and prevalence of intra-oral lesions within the rural district of UGU, KZN, South Africa as compared to global studies.Item The patterns and distribution of maxillofacial fractures at Pelonomi hospital(University of the Witwatersrand, Johannesburg, 2023-10) Mvala, Boyisile Stephen; Rikhotso, Risimati EphraimBackground: Despite large volumes of trauma patients treated, no study has analysed the epidemiology of craniofacial trauma at Pelonomi Hospital. Such studies could provide insight into the aetiologies and treatment modalities of maxillofacial injuries; and allow for development of strategies to ensure efficient and optimal utilization of limited health resources. Aim: To analyse the patterns and distribution of maxillofacial fractures at Pelonomi Hospital (PH). Methods: We designed and implemented a retrospective, descriptive cross-sectional study whose sample consisted of patients treated for maxillofacial fractures at PH, Frees State, South Africa, between January 1, 2017, and December 31, 2019. Data was collected from the patient’s clinical and radiographic records. Variables recorded included demographic data (gender, age), aetiology of the trauma, type of fractures and type of treatment provided. The delay in treatment was determined from date of injury to the day of treatment. The referral letters were assessed to determine district from which the patients were referred. Descriptive statistics of frequency and percentage were used to analyse the data. Fischer’s exact test was used to determine the association between the independent and dependent variables. The level of significance was set at a p-value less than 0.05. Results: A total of 307 patients with craniofacial fractures were included in the study. Females constituted 21.8% (n=67) and males were by far the majority of the participants at 78.2% (n=240). Individuals in the 20-29 age group had the most maxillofacial fractures (41.2%) and majority of patients in the study were Black (81.1%). The major cause of these injuries was interpersonal violence (60.9%). Alcohol contributed in 64.50% of the injuries. The most frequent fracture was a mandible fracture (70.7%). Majority of fractures in the study were treated with closed reduction (52%) and the waiting period prior to treatment was found to be 2 weeks. Conclusion: Blunt trauma sustained under the influence of alcohol in young individuals is responsible for majority of maxillofacial fractures at Pelonomi Hospital. Future prospective studies with large patient numbers and post treatment follow up are recommended.
