An interdisciplinary approach to management of diastemas: A novel classification and a case report.

Diastema between the teeth negatively affects the patients' smile, psychology and daily activities by creating a disharmony in the patients' face. The development of diastema has been attributed to several factors such as labial frenulum, microdontia, mesiodens, peg-shaped lateral incisors, agenesis, cysts, habits such as finger sucking, tongue thrusting, or lip sucking, dental malformations, genetics, proclinations, dental-skeletal discrepancies, and imperfect coalescence of interdental septum. Patients often present with complex problems that require a multidisciplinary treatment approach which includes determination of the aetiological factors, soft tissue morphology, occlusion, patient demands and aesthetic consideration to achieve satisfactory outcomes.

Salivary melatonin is depleted in patients with dental caries due to the elevated oxidative stress.

Objectives: To determine salivary melatonin and malondialdehyde levels in individuals with and without dental caries.

Materials And Methods: Saliva samples were collected in a fasting state from patients with active dental caries (n ​= ​16) and patients without dental caries (n ​= ​16). Melatonin was measured in the samples using a commercially available ELISA kit and malondialdehyde was assayed using a standardized spectrophotometric method.

Fracture resistance of resin based and lithium disilicate endocrowns. Which is better? - A systematic review of studies.

The primary objective of this systematic review is to compare the fracture resistance of lithium disilicate (LDS)-based endocrowns and resin-based (RB) endocrowns of in-vitro studies, and the secondary objective is to compare their catastrophic failures. The review protocol was registered in the P ROSP ERO database (CRD42020166201). A comprehensive literature search was done in PubMed, Cochrane, EBSCOhost and Google Scholar using key terms.
