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 ...
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.
Examples of the most common tissues examined by means of a biopsy include oral and sinus mucosa, bone, soft tissue, skin and lymph nodes. [6] Types of biopsies typically used for diagnosing oral and maxillofacial pathology are: Excisional biopsy: A small lesion is totally excised. This method is preferred if the lesions are approximately 1 cm ...
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
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.
The lesions are harmless; no treatment is indicated beyond reassurance unless the person requests it. The most common and simple treatment is the construction of a specially made acrylic prosthesis that covers the biting surfaces of the teeth and protects the cheek, tongue, and labial mucosa (an occlusal splint ).
Treatment depends on the underlying cause and severity. Endodontic treatment is the primary intervention in cases of pulpal infection. Other treatment options include Antibiotics that are prescribed for associated bacterial infections and tooth Extraction: Reserved for cases where the tooth is irreversibly damaged due to pulpitis.
Treatment is only required if the occlusion or bite of the person is compromised and causing other dental problems. Multiple long-term clinical problems can arise such as occlusal interferences, aesthetic disturbances, loss of pulp vitality, irritation of tongue during mastication and speech, caries and displacement of the affected tooth.
