Thermal Coefficients of Paste-Paste Type Pulp Capping Cements
Dental Materials Journal, 1992 Thermal coefficients of four kinds of commercially available paste-paste type pulp capping cements were examined. Control reference samples were made of dentin. A thermal coefficient analyzer was used, heating specimens for a few nanoseconds by a xenon flash bulb and measuring thermal changes by using a thermocouple.

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...
