Effect of Distinctive Moisture Conditions on Push-out Bond Strength of Three Root Canal Sealers-An Study.

Objective: Endodontic sealer should adhere to both dentin and the core filling material but the moisture conditions of the canals affect the adhesive properties of the sealer. An ideal sealer with perfect moisture conditions will lead to greater strength of the restored tooth, which may provide greater resistance to tooth fracture and clinical longevity of an endodontically treated tooth. The aim of this study was to evaluate the effect of moisture conditions on the push-out bond strength of three root canal sealers: AH Plus (Dentsply-Tulsa Dental, Tulsa, OK), Epiphany (Pentron Clinical Technologies, Wallingford, CT), and GuttaFlow (Coltene/Whaledent, Altstatten, Switzerland).

Role of topical drugs in treatment of oral mucosal diseases. A literature review.

Few topical formulations have been designed specifically to treat oral mucosal diseases. Local drug delivery may provide a more targeted and efficient option than systemic delivery for diseases of the oral mucosa. The permeability to the topical drugs differs according to the thickness of the epithelium and the extent of keratinization.
