Background:The success of root canal therapy requires a good knowledge of root canal morphology. Literature review shows variations in a number of roots and canal morphology in studies done across the globe.Aim:The purpose of this study was to evaluate the root canal morphology in maxillary first premolars using the clearing technique in a South Indian population.Methodology:Two hundred and twenty-five extracted noncarious, nonfractured, sound maxillary first premolars were collected, cleaned, and were injected with India ink to stain the root canals. Teeth were then decalcified and cleared using methyl salicylate. Teeth were then viewed under a stereomicroscope to evaluate the number of roots, root canal morphology based on the Vertucci's classification, variations, and additional features such as accessory root canals, lateral canals, furcation canals, isthmus, and apical delta.Results:Nearly 52.88% of maxillary first premolars were single rooted, 44.88% had two roots, and 2.22% had three roots. Vertucci's Type IV root canal configuration was the most common type in maxillary first premolars and was seen in 66.51% of cases followed by Type II in 13.4%. Type I was seen in 9.76%, Type VI in 6.51%, Type VIII in 2.32%, Type III in 0.46%, Type V in 0.46%, and Type VII in 0% of teeth.Conclusion:The majority of the maxillary first premolars included in our study were single rooted and Vertucci's Type IV was the most common type of root canal configuration.

Introduction: India introduced the Cigarettes and Other Tobacco Products Act (COTPA) (Packaging and Labeling [P and L]) Rules in 2008. These rules utilize the tobacco package to communicate tobacco-caused harms; it also seeks to restrict the delivery of misleading information about the product on the pack. The enormous burden of tobacco-related oral cancers in India necessitates the compliance with the law regarding presentation of information in powerful and salient ways, intentionally designed to increase the awareness in target individuals. Objectives: The objectives of the study are to assess the compliance to implementation and enforcement of the COTPA (P and L) Rules, 2008 and its amendments in 2014 and 2018. Materials and Methods: Chewing tobacco products were retrieved and evaluated for compliance with the law. The specified pictorial and textual health warnings, area, clarity, rotation, and language were assessed as per the recommendations. Results and Conclusion: Even though chewing tobacco products in India have introduced pictorial and textual health warnings, majority of them do not comply with the law. The products displayed the specified health warnings on a total of 70.6% on average, failing to abide by the government-specified average of 85%. 50% of the products did not follow the rotation of pictorial and textual health warning even after completion of the interregnum period of 12 months (September 2019). To ensure consumers’ right to be informed about the health risks from a product, all the details regarding the contents, health warnings and messages, and product care instructions must be mentioned as specified under the law.
