An analysis of the palatal surface anatomy of maxillary central incisors: complexity behind the simplicity.

Background: The palatal surface of the maxillary anterior teeth in conjunction with the incisal edge represents the mechanical area, which is of great importance for lateral and anterior guidance. Therefore, in terms of restorative dentistry, it is crucial for the clinician to have a detailed knowledge of the palatal surface anatomy (PSA) of the different maxillary anterior teeth in order to reestablish a definitive correlation between form, function, and esthetics. The aim of the present study was to analyze the variations in the PSA of the maxillary central incisors (CIs) and their correlation with tooth form and gender.

Extracellular matrix degradation by host matrix metalloproteinases in restorative dentistry and endodontics: An overview.

Matrix metalloproteinases (MMPs) are a group of over 25 secreted and membrane-bound enzymes responsible for pericellular substrate degeneration. In response to injury, they play key roles in morphogenesis, wound healing, tissue repair and remodeling. They have been isolated from dentin, odontoblasts, pulp and periapical tissue.
