Cone-Beam Computed Tomography Assessment of Root Canal Morphological Variations in Maxillary Second Premolars.

Background and objective A comprehensive understanding of root canal morphology and its anatomical variations is critical for the success of root canal treatment (RCT). Unrecognized variations may lead to incomplete cleaning, shaping, and obturation, potentially resulting in treatment failure. This study aimed to evaluate the frequency and distribution of root canal configuration types in maxillary second premolars (Mx2P) and their association with gender using cone-beam computed tomography (CBCT).

Comparison of severity of periodontal clinical parameters among naswar/snuff users: Cross sectional study.

Background: Naswar is a moist, non-chewable, and smokeless tobacco product ensconced in the buccal vestibule or floor of the mouth. Consumption of naswar is very popular in South Asia, especially Pakistan. This cross-sectional study compared the periodontal clinical parameters amongst mild, moderate, and severe naswar users.
