Anatomy and Physiology in Clinical Dental Practice

Dental clinical competence rests on precise knowledge of craniofacial anatomy and the physiology of the dentition, periodontium, and oral tissues. This note synthesizes anatomical landmarks relevant to local anesthesia, extractions, and implant planning, alongside the physiological basis of tooth attachment, healing, and the inflammatory response to caries and periodontal challenge. Understanding tooth microstructure—dentin permeability, enamel mineralization, cementum composition—explains clinical observations and guides preventive and restorative strategy. Clinicians who master functional anatomy practice safer, more effective dentistry.
