Comparative Evaluation of Four Different Obturating Techniques in Primary Teeth Using Cone-beam Computed Tomography: An In Vivo Study.

Background: The quality of the obturation plays a significant role in the success of endodontic treatment. To date, various technologies have been used to evaluate the quality of obturation, but all of them have their own limitations. In order to overcome those limitations, recent technological advancements like cone-beam computed tomography (CBCT) can be helpful. Aim: To compare and evaluate the efficiency of different root canal obturation techniques in primary teeth using CBCT. Materials and methods: A total of 80 root canals in 30 children aged between 4 and 9 years were selected and divided into four groups, with 20 root canals in each. Obturation in group I was performed using the endodontic pressure syringe; group II-hand spreaders; group III-Lentulo spirals mounted on slow-speed handpiece; and group IV-insulin syringe. The quality of obturation was evaluated using a CBCT scan. Results: Group I samples showed the most optimally filled canals followed by II and III; least in group IV. A maximum number of overfilled canals was exhibited in group III samples. Voids were minimal in all four groups and the values obtained were not statistically significant. Conclusion: Obturation with an endodontic pressure syringe reported the highest number of optimally filled root canals and the insulin syringe showed the least number of optimally filled canals.

Osteomyelitis of the mandible in patients with a history of COVID-19 infection: clinical, histologic, and radiographic presentations.

COVID-19 is a serious global infectious disease impairing the quality of life of people across the world. SARS-CoV-2 may reside in nasopharyngeal and salivary secretions of COVID-19-infected patients and spreads mainly through respiratory droplets and fomites. It has presented a challenge to dentistry, as many dental procedures generate aerosols that could lead to cross-contamination. It also presents many post-infection complications that may continue to debilitate patients, even after successful management of the virus. One such complication may be osteomyelitis of the jaw. Two cases of post-COVID-19 osteomyelitis of the jaw are presented that were determined to be unrelated to mucormycosis in otherwise healthy individuals with no prior dental complaints. An attempt is made to shed light on clinical signs in post-COVID cases that may point to a diagnosis of the condition. The pathophysiology is also discussed, which may help in formulating guidelines to prevent and manage post-COVID osteomyelitis of the jaw.

Granulomatous Diseases Affecting Jaws.

The common aspect of all granulomatous diseases is the typical form of chronic inflammatory response with distinct microscopic granulomas that are formed secondary to either definitive etiologic agents, like bacteria, fungal, or parasitic, or due to an unknown etiologic agent, such as trauma, autoimmune, or even neoplastic process. Although they can be histologically distinct, granulomatous diseases demonstrate a variety of clinical features that may not seem to be inflammatory. Two types of granulomas are typically encountered: foreign body granulomas and immune granulomas. The differences between the two types of granulomas lie in the pathogenesis.

Bilateral coronoid hypoplasia and complex odontoma: a rare concurrence of developmental pathology and odontogenic tumour of the mandible.

We present a rare case of concurrent bilateral coronoid hypoplasia and complex odontoma in the mandible, with replacement of missing posterior teeth in both sides of the lower jaw. A 20-year-old woman was diagnosed with bilateral occurrence of coronoid hypoplasia and unerupted complex odontoma after radiographic and histopathological examination. The patient was surgically treated with complete removal of the unerupted complex odontoma and prosthetic replacement of the missing teeth.
