ABSTRACT
Introduction/background: The preventive benefits of pit and fissure sealants rely on their retention and sealing ability. The drawback of the conventional pit and fissure sealant is its poor retention due to the presence of moisture. Among the numerous pit and fissure sealants available, newer hydrophilic sealants are ideal for children. This study evaluates and compares the sealing ability of hydrophilic sealant Embrace WetBond with conventionally used glass ionomer sealant under a stereomicroscope. Materials and methods: A total of 48 extracted human premolars were randomly divided into two groups (N = 24) and sealed with Embrace WetBond and GC Fuji VII as per manufacturers' instructions. Following thermocycling, the sectioned samples were evaluated for sealant penetration, unfilled space, and total length of fissure under a stereomicroscope at magnifications 2.5×, 4×, and 5×. The values were measured in microns and in various fissure types using the "ImageJ app" to measure the sealant penetrability and sealing ability. The data recorded were statistically evaluated. Results: The penetrability of moisture-tolerant sealant was better (87.8 ± 10.7) compared to that of glass ionomer sealant (73.8 ± 15.5) (p = 0.002). Among the samples, U-type fissure patterns displayed greater penetrability (94.2 ± 6.2), whereas IK-type fissures revealed the lowest degree of penetrability (67.5 ± 7.3). Conclusion: Embrace WetBond is better than glass ionomer sealant with respect to penetrability and sealing ability under stereomicroscope hence recommended as a better sealant for pediatric clinical practice.

ABSTRACT
Even in the 21st century, dental caries are considered a global burden, severely upsetting the health and quality of life of those affected. Apart from the fluoride use and regular oral hygiene, one of the most important prophylactic approaches against caries occurrence is the sealing of pits and ï¬ssures. Pit and fissure sealants are a core part of the preventive program in pediatric dentistry and should be considered as a key component of minimally invasive dentistry due to their broad patient benefit. The primary sealant efficacy measure is retention. If the sealant remains bonded to the tooth and offers a good seal, then it is right to expect the occurrence of caries to be diminished. Traditional pit and fissure sealants are hydrophobic. These materials are based on bisphenol A-glycidyl methacrylate (bis-GMA) and other monomers requiring a dry field which is hard to achieve in an oral environment, especially for children. This review highlights the literature on the effectiveness of moisture tolerant pit and fissure sealant, which are the hydrophilic pit and fissure sealant, and a general overview of the pit and ï¬ssure sealant materials used for sealing occlusal surfaces, its classification as well as indications and possible side effects.

ABSTRACT
OBJECTIVE: In children, manual dexterity poses a problem with the use of manual tooth brushes (MB), resulting in inefficient plaque removal. Recently, novel chewable brushes (CB) have been introduced which could overcome this problem but are less researched in children. The objective of this study is to assess and compare the plaque removal effectiveness of CB with that of MB. MATERIALS AND METHODS: A total of 60 patients aged 8 to 10 years were enrolled in a single-blinded randomized clinical trial. At baseline, disclosing solution was applied and the Turesky modification of the Quigley-Hein index (TQHI) plaque index and Loe and Silness gingival index were recorded. The subjects were randomly divided into two groups as group I (MB) and group II (CB) and they were instructed to use their respective brushes for a period of 1 week. For statistical comparison, the difference (prebrushing minus postbrushing) in average scores was calculated. Data were evaluated by the independent t test and paired t test, with p < 0.05. RESULTS: The overall plaque scores reduced from 1.71 ± 0.4 to 0.79 ± 0.24 when using CB and from 1.64 ± 0.64 to 1.13 ± 0.47 when using MBs. On lingual tooth surfaces, CB showed a plaque reduction of 38.70 ± 11.04 to 12.60 ± 4.79 compared to less reduction from 37.43 ± 14.26 to 28.73 ± 11.37 for MB. The overall gingival scores were also reduced from 0.33 ± 0.51 to 0.09 ± 0.07 when using CB and from 0.30 ± 0.33 to 0.19 ± 0.23 when using MB. Differences in scores between the two brushes were statistically significant (p = 0.0001). CONCLUSION: It was concluded that the experimental CB was able to remove a significant amount of plaque, particularly on the lingual surfaces, and reduced gingival index scores, thereby improving oral hygiene and gingival health status.

ABSTRACT
INTRODUCTION: In India, the trend indicates an increase in oral health problems especially dental caries, which has been consistently increasing both in prevalence and in severity. Children of all age groups are affected by dental caries. It becomes imperative to collect the data on prevalence of dental caries and treatment needs to provide preventive care. AIM: To assess the prevalence of dental caries and treatment needs of 6-11years old Indian school children. MATERIALS AND METHODS: This was a cross-sectional study. Sampling frame consisted of 6-11years old primary school children. Study sample consisted of 13,200 children selected from 10 talukas of Belgavi District, Karnataka, India. Clinical examination for dmft and DMFT was carried out in the school premises by five teams, each consisting of one faculty, three postgraduate students and five interns from the KLE VK Institute of Dental Sciences, Belagavi, Karnataka, India. The examiners were trained and calibrated by the principal investigator. Statistical analysis was done using Chi-square and t-test. RESULTS: The overall caries prevalence was 78.9%, mean dmft was 2.97±2.62 and mean DMFT was 0.17±0.53. The decayed teeth component was the principal component in both dmft and DMFT indices. The mean dmft in boys was higher compared to girls and it was found to be statistically significant (p<0.05). CONCLUSION: This study provided us with the baseline data, using which treatment was provided to all the children screened. The children were provided treatment at the camp site/dental hospital/satellite centers and primary health care centers according to the facilities available.
