Aim:To evaluate and compare the retention ability, anticaries effect and marginal discoloration when sealed with a glass ionomer-based sealant (Fusion i-seal) and a resin-based fissure sealant (Helioseal-F) on permanent first molars. Materials and methods: Caries free, fully erupted permanent first molars of 50 children between 6 years and 8 years were sealed with pit and fissure sealants under rubber dam isolation. Glass ionomer-based sealant was applied on a permanent first molar and the contralateral molar with resin-based sealant. The sealants were evaluated at regular intervals for a period of 1 year. Statistical analysis was done by Chi-square test. Results: Higher retention rates were noted for resin-based sealant (88%) compared to glass ionomer-based sealant (78%). None of the teeth sealed with resin sealant developed caries whereas 2% of teeth sealed with glass ionomer sealant developed caries. Marginal discoloration was not noted in teeth sealed with glass ionomer sealant whereas slight marginal discoloration was noted for 6% of teeth sealed with resin sealant. Conclusion: Clinically a difference was noted in the retention rate, anticaries effect and marginal discoloration whereas statistically no significant difference was noted for the two sealants after 1 year. Clinical significance: Pit and fissure sealants are highly effective and economical in preventing occlusal caries in young permanent tooth with low failure rate. 554compared with the retention and anticaries properties of a resinbased fissure sealant (Helioseal-F).

To evaluate the parental perception of oral health related quality of life and barriers to access dental care among children with intellectual needs. Method: This cross sectional study was conducted among randomly selected 300 parents of children aged 4-12 years with intellectual needs (mental retardation, cerebral palsy, epilepsy, autism). Data on oral health related quality of life (OHRQoL) were collected with parental-caregivers perceptions questionnaire (P-CPQ). DMFT/dmft index was used to express caries prevalence as per World Health Organisation. Chi-squared test, analysis of variance, t-test and correlation were performed. Results: Parents of children who fell in the high severity DMFT category reported higher score in all four domains of OHRQoL when compared to low severity and moderate severity. Parents of children suffering from autism had higher score in all four domain of OHRQoL (p = .000).Majority of the parents rated their children's oral health as either fair (47%) or poor (42%). Predominant barriers for access dental care were financial difficulties (35.3%), lack of knowledge about dental care (24%), transportation difficulties (15%). Conclusion:The present study revealed that higher caries prevalence has negative impact on OHRQoL of children with intellectual needs and their parents faced certain barriers for accessing dental care.

IntroductionAssessment of difference in caries prevalence among twins may help determine the character and the extent of the influence exercised by the environment, as a complement of the genetic constitution.AimTo investigate the inter-pair differences in caries prevalence among South Indian monozygotic twins in relation to birth weight, birth order, and gender. Possible correlation among other attributes such as breastfeeding, socioeconomic status, oral habits, frequency of brushing, and sweet intake were also assessed.Materials and methodsA sample of 40 monozygotic children between the age group of 6 and 12 was selected. The parents were asked to complete the questionnaire and report with their children. Then dental examinations were carried out and the prevalence of dental caries among the twins were assessed.ResultsAmong the total samples, 61.5% exhibited caries. Lower birth weight twins showed an increased chance of caries (72.22%), compared to higher birth weight twins (68.18%). Second of the twins had an increased risk of dental caries (70%) compared to the first (60%). 90% of the male twins and 45% of the female twins had caries. The association between dental caries and other variables were also assessed; those who were exclusively breastfed had an increased risk (70%) of caries. Evaluation of socioeconomic status and caries revealed a risk of for the high (65%), middle (62.5%), and lower groups (58.33%). Children without oral habits showed a higher prevalence (73.3%) of caries when compared to those without any habits (50%). It was noticed that the brushing frequency is not related to the severity of caries. The strongest association was noticed between excessive sweet liking and prevalence of dental caries.ConclusionThe study revealed difference in caries prevalence among monozygotic twins in relation to birth weight, birth order, and gender. It was found that variations in caries prevalence existed with other attributes also.How to cite this articleZarina R, Kuriakose S, et al.
