Assessment of Treatment Outcomes with Complete Orthograde Obturation with Bioceramic Materials: A Scoping Review.

Aim: Bioceramic sealers are being used as obturation materials as they are known for hard tissue induction and facilitating periapical healing. Based on some studies, one can hypothesize that mineral trioxide aggregate (MTA) and biodentine used as the sole obturating material could reinforce the tooth and provide a better sealability than an MTA/biodentine apical plug with gutta-percha obturation. However, there are not many high-quality studies regarding outcomes of complete MTA/biodentine obturations compared with traditional obturation methods.

Antibiofilm efficiency of silver and copper nanoparticle incorporated calcium hydroxide as an intracanal medicament: An study.

This study aimed to assess the antibiofilm efficiency of calcium hydroxide modified with Ag and Cu NP suspension against , using confocal laser scanning microscopy (CLSM) and colony forming units (CFU) analysis.

Methods: Dentine blocks were inoculated with Enterococcus faecalis for one week and 1 week-old biofilm of were randomly divided into 4 groups, control, calcium hydroxide, calcium hydroxide +2 % Cu NP and calcium hydroxide +2 % Ag NP.

Immunomodulatory effects of Triphala and its constituents in oral squamous cell carcinoma and oral precancer.

Oral squamous cell carcinoma shows increased occurrence in those who consume tobacco products, alcohol, betel quid, and areca nut, and is also considered to occur due to genetic alteration. Though there are numerous advancements in treatment, survival remains a question with late diagnosis. Hence, there are continuous inventions of new drugs.

Determination of Barr bodies in Transgender Patients in India - A comparative study.

Unlabelled: Sex determination in forensic medicine is considered one of the first and foremost steps in personal identification. The need for identifying the exact sex of the individual arises when deciding whether a person can exercise certain civil rights reserved for one particular sex, for competing in sex-specific athletic and sports events, legitimacy, divorce, paternity disputes and also to some criminal offenses. Nuclear sexing by Barr body examination can be done using buccal smears to establish the sex of the individual when routine methods fail to disclose the exact gender of the individual.

Radiologic-Pathologic correlation of Pindborg tumor of maxilla with extension to maxillary sinus, nasal cavity, and infraorbital margin: A case report.

Calcifying epithelial odontogenic tumor is a benign epithelial odontogenic tumor thought to originate from the stratum intermedium. Clear cell type, Langerhans cell/non-calcified type, and cystic/microcystic are the three recently recognized histological subtypes of CEOT in the 5th edition of the World Health Organization Classification of Head and Neck Tumors. Almost 350-400 cases of CEOT have been reported in literature, accounting for less than 1% of the reported cases of odontogenic tumors.
