METHODS: A cross-sectional study was conducted involving 1150, 5-6 year-old preschool children in Selangor, Malaysia. Mothers answered a questionnaire on socio-economic status, the Malay-Modified Dental Anxiety Scale to assess maternal dental anxiety, and the Malay-Early Childhood Oral Health Impact Scale to assess COHRQoL. Child's dental anxiety was assessed using the Malay-Modified Child Dental Anxiety Scale via a face-to-face interview prior to oral examination to assess dental caries. Data were analysed using structural equation modelling to assess the relationship between maternal and child dental anxiety and COHRQoL.
RESULTS: Overall, complete data on 842 mother-child dyads were analysed. The mean scores of total ECOHIS, the child impacts section (CIS), and the family impacts section (FIS) were 17.7 (SD = 4.9), 12.6 (SD = 3.7), and 5.1 (SD = 1.9), respectively. The mean dental anxiety scores for mothers and children were 11.8 (SD = 4.5) and 16.9 (SD = 4.3), respectively. Maternal dental anxiety was associated with the CIS (b = 0.08, p dental caries experience and COHRQoL (p dental anxiety and child's dental caries experience have significantly impacted the COHRQoL, the CIS, and the FIS domains. Demographic factors such as maternal education, income, urban/rural location, and kindergarten type acted as moderators that can strengthen or weaken the relationship between maternal dental anxiety and COHRQoL of 5-6-year-old preschool children.
METHODS: Cross sectional data collected on school children in eight rural and urban schools through the national Incremental Dental Care Programme (IDCP) for one district in Malaysia were analysed to assess their annual caries increment and trend lines. The Restorative Index was calculated to assess the success of the IDCP in rendering children dentally fit.
RESULTS: The annual caries increments were low; the current caries levels were between 0.65 and 1.50 for 12 year-old children in Kota Tinggi District. Most of the caries experience was on pits and fissures. From 7 to 12 years old, the overall annual caries increment for the total study population was 0.19. The mean annual caries increment increased slightly between the ages of 12 to 14 years and 14 to 16 years and was 0.24 and 0.25 respectively. Two distinct caries incremental trend lines were observed for children aged 7 to 16 years. One group reached a mean DMFT of about 0.75 while the other group a mean DMFT of about 1.4 at 12 years. The trend lines continued over the next 4 years until the children were 16 years old. The Restorative Index was higher in urban schools that also had low DMFT levels.
CONCLUSIONS: Based on the low annual caries increments of between 0.65 and 1.50, yearly dental examination intervals can safely be extended to 2-yearly intervals or even longer. Such a change of screening recall intervals would help improve resource allocation. Resources saved by extending recall intervals can be redirected to the small proportion of children with higher disease levels. This will help render more school children dentally fit and reduce inequalities in oral health.
Objectives: The aim of this study was to assess the relationship between khat and occlusal caries progression.
Methods: A cohort study was carried out among 98 Yemeni khat chewers and 101 non-chewers aged 18-35 years old with early occlusal caries lesions. All participants answered questions on socio-demographic, khat , oral hygiene , sugar intake, and oral health knowledge at baseline. All posterior teeth with an early enamel lesion on occlusal surfaces detected by visual inspection at baseline were also subjected to DIAGNOdent assessment to confirm early lesion (DIAGNOdent reading 13-24). Participants were re-examined after 12 weeks. Caries progression was considered to occur when the DIAGNOdent reading was >25. Data were analyzed using Relative risk, Mann-Whitney U test, a Wilcoxon Signed-Rank test and logistic regression analysis.
Results: Occlusal caries progression incidence between khat chewers and non-chewers, with the relative risk was 1.68. There was no significant difference in occlusal caries progression on chewing side and non-chewing side among khat chewers. Khat chewing was a statistical predictor for those with low income.
Conclusion: Khat is a risk factor for occlusion caries progression among low income group.
METHODOLOGY: This study was approved by the institutional Joint Research and Ethics Committee, International Medical University, Malaysia (number 373/2016); consisted of 180 eligible pre-school children from a private school. Study tools included demographic, clinical oral health data form, the Early Childhood Oral Health Impact Scale (ECOHIS) and family functioning-12-item general functioning subscale. Written consent was sought prior to data collection. Data were analysed by SPSS v.22.0; descriptive statistics for socio-demographic details, clinical information, HRQoL and FAD scores. The parametric tests included independent sample t test and ANOVA to evaluate the associations between the dependent variable. Binary logistic regression models were applied to assess the impacts on OHRQoL (P value dental caries had a significant (P = 0.014) negative impact on OHRQoL (mean 0.72, SD = 0.50) as compared to children with no caries (mean 0.34 SD = 0.39). The bivariate regression analysis after getting adjusted indicated three predictors associated to poor HRQoL: having two or more siblings (OR = 4.73, P = 0.013), relationship (mother) of the respondent to the child (OR = 2.86, P = 0.013) and having dental caries (OR = 8.12, P ≤ 0.001).
CONCLUSION: Findings of this study indicates that number of siblings, relationship of the respondent to the child and dental caries status are independently associated with health-related quality of life. However, family functioning does not mediate poor HRQoL in association to dental caries.
