What Causes Malformed Central Incisors?
The etiology of malformed central incisor is mainly due to long-term occlusal wear that leads to the communication of the pulp chamber, causing symptoms of acute toothache. This pain is mainly caused by pulpitis and nerve stimulation. Timely anti-inflammatory treatment during the acute phase is recommended, and after the inflammation improves, timely central incisor restoration treatment should be performed, with symptomatic treatment based on the severity of the condition.
The toothache symptoms caused by malformed central incisor are mainly due to the wear of the central incisor during occlusion, which directly leads to communication with the pulp chamber, thus easily causing pulpitis or stimulating the tooth nerve and causing toothache. In addition to anti-inflammatory and analgesic treatment during the acute phase, timely restoration of the central incisor is required during the stable phase.
1. Low and blunt central incisors with no symptoms in the affected teeth do not require treatment.
2. High and sharp central incisors should be gradually adjusted and polished before the establishment of occlusion relationships, with an interval of 2-3 weeks between each adjustment. The thickness of each polishing should not exceed 0.5mm, and 75% sodium fluoride glycerin paste should be applied after adjustment and polishing. If the X-ray shows pulp horn protrusion into the tip, direct pulp capping should be performed as soon as possible.
3. In cases of young permanent teeth with concurrent pulp disease, direct pulp capping or pulpotomy should be performed; for concurrent apical periodontitis, apical induction should be performed.
4. For adult teeth with concurrent pulp and apical periodontitis, root canal treatment should be performed; if the tooth root formation is less than 1/2 and secondary periodontal disease occurs, the tooth should be extracted.
