Socio-demographic and behavioural correlates of oral hygiene status and oral health related quality of life, the Limpopo - Arusha school health project (LASH): A cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Promoting oral health of adolescents is important for improvement of oral health globally. This study used baseline-data from LASH-project targeting secondary students to; 1) assess frequency of poor oral hygiene status and oral impacts on daily performances, OIDP, by socio-demographic and behavioural characteristics, 2) examine whether socio-economic and behavioural correlates of oral hygiene status and OIDP differed by gender and 3) examine whether socio-demographic disparity in oral health was explained by oral health-related behaviours.</p> <p>Methods</p> <p>Cross-sectional study was conducted in 2009 using one-stage cluster sampling design. Total of 2412 students (mean age 15.2 yr) completed self-administered questionnaires, whereas 1077 (mean age 14.9 yr) underwent dental-examination. Bivariate analyses were conducted using cross-tabulations and chi-square statistics. Multiple variable analyses were conducted using stepwise standardized logistic regression (SLR) with odds ratios and 95% Confidence intervals (CI).</p> <p>Results</p> <p>44.8% presented with fair to poor OHIS and 48.2% reported any OIDP. Older students, those from low socio-economic status families, had parents who couldn't afford dental care and had low educational-level reported oral impacts, poor oral hygiene, irregular toothbrushing, less dental attendance and fewer intakes of sugar-sweetened drinks more frequently than their counterparts. Stepwise logistic regression revealed that reporting any OIDP was independently associated with; older age-groups, parents do not afford dental care, smoking experience, no dental visits and fewer intakes of sugar-sweetened soft drinks. Behavioural factors accounted partly for association between low family SES and OIDP. Low family SES, no dental attendance and smoking experience were most important in males. Low family SES and fewer intakes of sugar-sweetened soft drinks were the most important correlates in females.</p> <p>Socio-behavioural factors associated with higher odds ratios for poor OHIS were; older age, belonging to the poorest household category and having parents who did not afford dental care across both genders.</p> <p>Conclusion</p> <p>Disparities in oral hygiene status and OIDP existed in relation to age, affording dental care, smoking and intake of sugar sweetened soft drinks. Gender differences should be considered in intervention studies, and modifiable behaviours have some relevance in reducing social disparity in oral health.</p

Maternal oral health status and preterm low birth weight at Muhimbili National Hospital, Tanzania: a case-control study

The study examined the relationship between oral health status (periodontal disease and carious pulpal exposure (CPE)) and preterm low-birth-weight (PTLBW) infant deliveries among Tanzanian-African mothers at Muhimbili National Hospital (MNH), Tanzania. A retrospective case-control study was conducted, involving 373 postpartum mothers aged 14-44 years (PTLBW--150 cases) and at term normal-birth-weight (TNBW)--223 controls), using structured questionnaire and full-mouth examination for periodontal and dentition status. The mean number of sites with gingival bleeding was higher in PTLBW than in TNBW (P = 0.026). No significant differences were observed for sites with plaque, calculus, teeth with decay, missing, filling (DMFT) between PTLBW and TNBW. Controlling for known risk factors in all post-partum (n = 373), and primiparaous (n = 206) mothers, no significant differences were found regarding periodontal disease diagnosis threshold (PDT) (four sites or more that had probing periodontal pocket depth 4+mm and gingival bleeding > or = 30% sites), and CPE between cases and controls. Significant risk factors for PTLBW among primi- and multiparous mothers together were age < or = 19 years (adjusted Odds Ratio (aOR) = 2.09, 95% Confidence interval (95% CI): 1.18-3.67, P = 0.011), hypertension (aOR = 2.44, (95% CI): 1.20-4.93, P = 0.013) and being un-married (aOR = 1.59, (95% CI): 1.00-2.53, P = 0.049). For primiparous mothers significant risk factors for PTLBW were age < or = 19 years (aOR = 2.07, 95% CI: 1.13 - 3.81, P = 0.019), and being un-married (aOR = 2.58, 95% CI: 1.42-4.67, P = 0.002). These clinical findings show no evidence for periodontal disease or carious pulpal exposure being significant risk factors in PTLBW infant delivery among Tanzanian-Africans mothers at MNH, except for young age, hypertension, and being unmarried. Further research incorporating periodontal pathogens is recommended

Patients' satisfaction with dental care provided by public dental clinics in Dar es Salaam, Tanzania

Background: In Tanzania, patient satisfaction with dental services has received only minor attention.Objective: To assess patients' satisfaction with public dental health services in Dar es Salaam. Design: A cross-sectional study. Setting: Five public dental clinics randomly selected from a list of all the nine public dental clinics in Dar es Salaam.Subjects: Five hundred and sixteen consecutive patients, 193 males and 323 females aged between 12 and 77 years who, during the study period between July and November, 2002 were attending five dental clinics were randomly selected. Results: No significant differences in patients' satisfaction level (overall or for the specific studied items) were found in all the five public dental clinics. The answers to the specific sub-items, apart from time spent with doctor, were around the average with very few responses with a high ranking. Conclusions: Findings indicate a moderate level of patient satisfaction with dental care offered in public dental clinics in Dar es Salaam. Areas identified as needing improvement included; technical quality of care, interpersonal aspects and communication. East African Medical Journal Vol. 83(4) 2006: 98-10
