INTRODUCTION: The role of complement, especially through the C5a fragment, is well-known for the initiation of inflammation. Its involvement in regeneration has been shown more recently by the recruitment of mesenchymal stem cells. C5a can be produced locally by the pulp fibroblasts in response to injury or infection. This work aims to investigate the effect of different pulp capping biomaterials on complement activation and its possible influence on inflammatory and pulp stem cell recruitment...

Periostitis ossificans, also known as Garré osteomyelitis, is a specific type of chronic osteomyelitis that forms new bone under the periosteum resulting from a periosteal reaction to chronic inflammation or infections. It commonly affects the mandible secondary to odontogenic infection. The therapeutic approach involves eliminating the infectious cause and antibiotic administration. This report describes an unusual case of periostitis ossificans arising from the mandible of an 11-year-old boy. The cause of infection was correlated with a lower right unerupted third molar, which had no obvious connection with the oral cavity...

Dentigerous cysts are benign odontogenic cysts associated with the crowns of unerupted, embedded, or impacted teeth. Most of them are associated with mandibular third molars, followed by maxillary third molars and canines. They are usually asymptomatic, and rarely do they grow extensively and compress the adjacent anatomic structures. We report 5 cases of extensive maxillary dentigerous cysts presenting with sinonasal and orbital symptoms. A literature review for similar presentations of dentigerous cysts has demonstrated 21 cases...

Deliberate falsification of age was considered to be one of the main reasons for forensic age estimation of the living individuals. This posed to be a challenging task during criminal and legal proceedings, and ultimate care must be taken not to classify juveniles as adults. Third molars are the only developing teeth during late adolescence and early adulthood. Our study was designed to analyze the usefulness of the third molar maturity index (I3M) specific cut-off value (I3M < 0.08) to discriminate adults (≥18 years) and juveniles (<18 years) in South Indian children...
