This condition arises as a response to dental infections, such as periapical pulp inflammation or low-intensity trauma. The lesion typically appears as a radiopacity in the periapical area due to the sclerotic reaction. While most commonly associated with non-vital teeth, condensing osteitis can also occur in vital teeth following occlusal trauma.
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Non-carious cervical lesions on an incisor belonging to Australopithecus africanus. Arrows show the location of the lesions. Non-carious cervical lesions (NCCLs) are a group of lesions that are characterised by a loss of hard dental tissue at the cementoenamel junction (CEJ) region at the neck of the tooth, without the action of microorganisms or inflammatory processes.

Anterior open bite resulted from tongue thrusting in a 24 y.o. patient. Anterior upper teeth are not touching their counterpart. Anterior open bite (AOB) is defined as a condition in which there is no contact and no vertical overlap of the lower incisor crown with the upper incisor crown when the mandible is in full occlusion. [19]
Class I: The molar relationship of the occlusion is normal or as described for the maxillary first molar, with malocclusion confined to anterior teeth [4] Class II : The retrusion of the lower jaw with distal occlusion of the lower teeth (or in other words, the maxillary first molar occludes anterior to the buccal groove of the mandibular first ...
Where there is a risk of pulpal exposure if lesion depth is severe enough. When retention of a removable appliance is interfered, i.e. denture; To improve denture clasp(s) retention. Overall integrity of tooth structure is compromised. In order for successful treatment of abrasion to occur, the aetiology first needs to be identified. The most ...
The word derives from mal- 'incorrect' and occlusion 'the manner in which opposing teeth meet'. The malocclusion classification is based on the relationship of the mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar. If this molar relationship exists, then the teeth can align into normal occlusion.
Molar relationship classification, observed when locating the mesial buccal cusp of the maxillary first molar and buccal groove of the mandibular first molar. (Institute of Dentistry, Aberdeen University) When discussing the occlusion of the posterior teeth, the classification refers to the first molars and may be divided into three categories:
