Objective:To determine caries experience and related risk factors in cerebral palsy (CP) children.Methods:Random sample of CP children was examined for dental caries and oral hygiene. Questionnaire was utilized for information about caries risk factors. This cross-sectional study was conducted in Riyadh from December 2014 to May 2015.Results:Fifty-two CP children were examined with mean age of 6.3±2.7 years. Only one (1.9%) child out of the 52 had no clinical caries. Combined (dmft plus DMFT) mean caries score among study sample was 9.98±3.99. Older children had significantly higher mean caries scores (11.5±3.34) than younger children (8.86±4.1, p=0.017). The CP children with good oral hygiene had lowest mean caries score (5.8±7.32) as compared to those with fair (9.72±3.3) and poor (11.55±3.05) oral hygiene (p=0.012). Those children whose first dental visit was for routine check-up had significantly (p=0.02) lower mean caries scores (7.33±4.65) than those who made their first visit due to dental problem (11.57±4.15). Similarly, those who had topical fluoride applications by dentist had significantly (p=0.003) lower mean caries scores (8.67±4.14) than those with no topical fluoride application (11.9±2.89).Conclusion:The studied CP children had very high caries experience and poor oral hygiene. There was strong association between the high caries experience and poor oral hygiene.

Parents of CP children generally showed satisfactory oral health comprehension. However, they need further oral health education in several areas.

Objectives. This in vitro study evaluated the quality of marginal seal and fissure penetration of a resin-sealant (Concise) and a compomer restorative material (F2000) with and without enameloplasty. Sample and design. Thirty extracted sound human permanent third molar teeth were divided into six groups of five and used in this in vitro study. Methods. Occlusal surfaces of the teeth in different groups were either left intact or prepared using a #582 S diamond bur. Teeth were then restored with Concise and F2000 restorative materials using combinations of different surface treatments. Teeth were prepared for microleakage, then immersed in 5% methylene blue for 4 h, and subsequently sectioned into four bucco-lingual sections. Sections (20 per group) were examined using a stereomicroscope. The following parameters were evaluated: marginal leakage, marginal gap, voids and filling defects, as well as enamel fissure penetration. Results. Kruskal-Wallis one-way anova showed statistically significant differences between the groups for marginal leakage ( P < 0·0001), marginal gap ( P < 0·001), and enamel fissure penetration ( P < 0·001). No statistically significant differences between the groups for voids and filling defects were detected. Non-parametric Tukey's multiple range test showed that microleakage of sealant with acid etch and tooth preparation and compomer with acid etch, bonding agent and tooth preparation were statistically significantly less than that of compomer with bonding agent and no tooth preparation ( P < 0·0001) and compomer with bonding agent and tooth preparation ( P < 0·01). Conclusions. Microleakage is similar when sealant with acid etching, and compomer with acid etching and bonding agent, are used with and without enameloplasty. Marginal gap is more evident in the compomer group with bonding agent and without enameloplasty. Enamel fissure penetration is better when enameloplasty and acid etching are used.

The objective of this study was to compare the retention and caries-preventive effect of glass ionomer (Fuji Triage) and resin-based (Clinpro) sealants among 6-9-year-old children. This split-mouth, randomized clinical trial covered 35 children/140 fully erupted permanent first molars. Evaluation was conducted by two independent examiners after 6, 12, and 18 months and the data were compared in relation to the children's caries risk and age groups. The Kaplan-Meier survival method and chi-square test were used for analysis. There were no statistically significant differences in the survival of partial and fully retained sealants or in the survival of caries-free pits and fissures between glass-ionomer and resin-based sealants. In terms of retention, both sealants performed better in the younger age group at the end of the study, and showed better caries prevention in moderate caries risk children. After 18 months, both sealants had comparable retention and caries-preventive effects in 6-9-year old children.

Both carbonated soft drink and fruit juice/drink accounted for the largest proportion of total fluid intake by the sampled Saudi adolescents to the detriment of nutritious milk.
