ABSTRACT
AIM: To determine the prevalence of early childhood caries (ECC) and its risk factors in children of West Godavari district, Andhra Pradesh. STUDY DESIGN: A sample of 1,897 children between 24 and 71 months of age based on stratified cluster random sampling were clinically examined for dental caries using mouth mirror under day light. The parents/caregivers of each child were interviewed with a structured questionnaire. Data was analyzed using independent sample Student's t-test and chi-square test. RESULTS: Out of the total 1,897 children, 796 were affected with ECC showing an overall prevalence of 41.9%, with boys showing a higher prevalence rate of 44.8% compared to girls (39.9%). Statistically significant correlations were found between ECC and consumption of sugary snacks (p < 0.0001) and mouth rinsing habit (p < 0.001). CONCLUSION: A higher prevalence of ECC was observed and most of the teeth were not restored. HOW TO CITE THIS ARTICLE: Koya S, Ravichandra KS, Arunkumar VA, Sahana S, Pushpalatha HM.

ABSTRACT
BACKGROUND: C-reactive protein (CRP) - a prototypic marker of inflammation has been shown to be elevated in chronic periodontitis (CP) and also been shown to predict cardiovascular events. Increased carotid intima media thickness (CIMT) has been recently recognized as surrogate marker for atherosclerosis. In this context, we studied to correlate between CIMT and CRP in CP and to know whether CRP predicts the cardiovascular risk in CP. MATERIALS AND METHODS: The study consisted of 30 systemically healthy subjects aged over 40 years - 15 subjects with CP as cases and 15 subjects with no periodontitis as controls. All subjects were subjected to measurement of CRP levels and CIMT in addition to detailed periodontal evaluation. Quantitative determination of CRP was done by turbidimetric immunoassay. IMT of the common carotid arteries was estimated bilaterally using B-mode ultrasound at 6 sites. Positive CRP was defined as more than 10 mg/l. RESULTS: Mean CRP levels were significantly higher in subjects with CP (19.58 ± 17.03), then in non CP (NCP) (5.54 ± 1.63, P < 0.004). Mean CIMT value was significantly higher in subjects with CP (1.09 ± 0.45) than in NCP (0.57 ± 0.06, P < 0.001) and all periodontal indices correlated well with CIMT. Further, there was significant correlation between CRP and increased CIMT in subjects with CP (r = 0.863, P < 0.001). CONCLUSIONS: The present study indicates CRP as a possible underlying pathway in the association between periodontal disease and the observed CIMT. CRP can be used as a risk predictor for atherosclerosis in patients with CP.
ABSTRACT
BACKGROUND: Dental caries among children is one of the greatest challenges faced by dentists globally; especially that of susceptible surfaces like the Pit and fissures. Dental sealants have proved to be an effective way to prevent caries development. The Clinical success of any material depends upon its adhesion to tooth structure, resistance to wear and ability to withstand the masticatory or occlusal forces. Hence it is important to evaluate the shear bond strength (SBS). The Present study's aim was to evaluate and compare the shear bond strength of different pit and fissure sealants placed on Primary molars and Permanent Premolars. MATERIALS & METHODS: Sixty noncarious extracted teeth comprising of thirty Primary molars and thirty Permanent Premolars were divided into four groups of 15 each. The buccal surfaces of all teeth were dried, etched and the etched surfaces of Primary molars (Group I) and Permanent Premolars (Group III) were placed with Helioseal-F while Groups II and IV, that included Primary molars and Permanent Premolars received Clinpro. Shear bond strength was evaluated and the mean was obtained for all the groups. The results were analyzed using twoway analysis of variance followed by Tukeys post hoc procedure to check for significant differences. RESULTS: The specimens of unfilled sealant Clinpro (Groups II & IV) showed higher Shear bond strength when compared to the specimens of filled sealant Helioseal-F (Groups I & III). CONCLUSION: The unfilled sealant showed a better Shear bond strength compared to the filled sealant. The bond strength in Primary molars was slightly higher compared to Permanent Premolars.
