Intrusive luxation of 60 permanent incisors: a retrospective study of treatment and outcome.

摘要: Background/Aim: Intrusive luxation in the permanent dentition is an uncommon injury but it considered one of most severe types dental trauma because risk for damage to periodontal ligament, pulp and alveolar bone. Management intrusive controversial. The purpose this study was evaluate survival healing luxated teeth relation treatment alternatives, degree intrusion root development. Material Method: material consisted 60 intruded 48 patients (32 boys 16 girls) aged 6-16 years (mean 9.4, median 9.0). observation time 6-130 months 47.8, 40.0). analysed treatments were spontaneous re-eruption (17 teeth), orthodontic extrusion (12 teeth) surgical reposition (31 teeth). registered as mild (0-3 mm), moderate (4-6 mm) (‡7 mm). Root development categorized with respect formation apex into four stages; one-quarter three-quarters formation, full open apex, half-closed closed. Ankylosis-related resorption necrosis diagnosed 20 teeth, ingrowth bone apically two without ankylosis- related 23 revitalization occurred 15 teeth. Results: Significant correlations outcome (P = 0.03) 0.03). Conclusions :N o firm conclusion could be drawn difference between reposition. To conclude, evaluation prognosis should based on stage intrusion. In immature development, no active appears result fewer complications.
