RESUMO
INTRODUCTION: Aggressive periodontitis (AP) is a condition that promotes breakdown of the periodontal tissues in a short time. In severe cases, pathologic migration of teeth and tooth loss can occur, producing esthetic and functional problems for the patient. Orthodontic treatment may be recommended to restore esthetics and masticatory function. We assessed the effects of orthodontic movement in the periodontal tissues of treated patients with AP. METHODS: Ten subjects (ages 25.0 ± 5.22 years) with AP received periodontal treatment followed by orthodontic treatment. Maintenance sessions were performed monthly under a strict dental biofilm control. They were compared with 10 periodontally healthy subjects (ages 22.9 ± 5.23 years) who received orthodontic treatment. Probing pocket depth, clinical attachment level, bleeding on probing, and dental plaque index were measured at baseline, after orthodontic treatment, and after 4 months. RESULTS: Statistical analysis showed improvement in all clinical parameters between baseline and 4 months after orthodontic treatment: probing pocket depth (0.29 mm), clinical attachment level (0.38 mm), bleeding on probing (4.0%), and dental plaque index (11%). CONCLUSIONS: The periodontal parameters of the AP patients remained stable during orthodontic treatment under strict biofilm control.

The aim of this randomized clinical trial was to carry out a biometric comparison between the orthodontic extrusion (OE, group B) technique and OE combined with fiberotomy and root planing (OEFRP, group A). Twenty single-root teeth were extruded and assigned to two different groups. In both groups, fixed orthodontic appliances were activated weekly during the course of 3 weeks. After activation, the extruded teeth were maintained in retention for a period of 8 weeks. In group A, along with weekly activation, fiberotomy and root planing were carried out on the top of the alveolar bone crest. Statistical analysis revealed that the amount of dental structure exposed was greater in group A, where the gingival margin and bone tissue remained stable (P < .05). Group B presented coronal migration of the gingival tissue and bone tissue of 2 mm and 1.5 mm, respectively.
