ABSTRACT
Background: In primary teeth, working length determination is complicated due to its continuous alteration in dimension, shape, and root apex position. Accurate working length determination is essential to achieve the optimal cleaning and disinfection of the canal. Despite the use of conventional radiographic method, newer methods are available to increase the accuracy of WL determination. This study aims to compare electronic apex locator (EAL) with radiographic method of WL determination and to evaluate its accuracy using cone-beam computed tomography (CBCT). Materials and methods: Sixty root canals from 34 extracted primary teeth were included. Occlusal surfaces were flattened and access opening done for all the samples. Teeth were subjected to working length determination by conventional radiograph and EAL. Samples were then mounted on a U-shaped wax and subjected to CBCT. Results were recorded and statistically analyzed using ANOVA and ICC for quantitative data. Result: The mean measurement of radiographic, EAL and CBCT methods are 11.708, 11.200, and 10.895, respectively. Mean measurements demonstrated significant difference (p < 0.05) between three methods. ICC demonstrated high correlation between EAL and CBCT with Cronbach's α value of 0.962 and moderate correlation were observed between radiographic method and CBCT (0.706) and EAL and radiographic method (0.763). EAL demonstrated 87% accuracy whereas radiographic method demonstrated 63% accuracy to the actual length as evaluated by CBCT. Conclusion: EAL is more accurate than conventional radiographic method as evaluated by CBCT. How to cite this article: Shibin J, GS P, M S, et al.

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
An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively. Correct diagnosis and treatment planning are fundamental to treatment of dens invaginatus. Periapical surgery is indicated in cases where a nonsurgical approach fails. A case of dens invaginatus type 3 in a maxillary lateral incisor with a periapical lesion and its successful treatment by these combined methods is reported.
