Mesioocclusal

Mesioocclusal refers to a specific location on a tooth. The term combines "mesial," which denotes the surface of a tooth closest to the midline of the dental arch, and "occlusal," which describes the chewing surface of the posterior teeth (molars and premolars). Therefore, mesioocclusal describes a condition or area located on the mesial aspect of the occlusal surface of a tooth. This term is frequently used in dentistry, particularly when diagnosing and describing cavities (dental caries) or restorations. For instance, a dentist might record a cavity as being "MO" or mesioocclusal, indicating its position on the tooth. This classification helps in treatment planning and communication among dental professionals. The mesioocclusal surface is a common site for decay due to its anatomical accessibility to food debris and plaque accumulation. Restorations placed in this area are designed to be durable and to withstand the forces of mastication.
