[Resin infiltration of white spot lesions during the fixed orthodontic appliance therapy]. / Infiltrarea cu rasina a leziunilor albe cretoase în timpul tratamentului ortodontic fix.

OBJECTIVE: To investigate the evolution of resin infiltrated white spot lesions (WSLs) during 10 month of fixed orthodontic appliance therapy using the photographic examination method. MATERIAL AND METHODS: Twelve patients with mild decalcifications prior to the orthodontic treatment were examined once each month. At aggravation of the WSLs, by patients who fail to maintain good oral hygiene, the brackets were taken down, the lesions were infiltrated with resin (ICON) and the brackets were bonded in place. WSLs were evaluated from intraoral photographs taken before and during the treatment. RESULTS: 35.2% of existing lesions aggravated in the first 6 months of treatment. 41.2 % of the W.S.L. were considered severe and were infiltrated. In the next 10 month of orthodontic treatment 92.5% of the infiltrated WSLs were clinically stable. CONCLUSIONS: This clinical study showed a positive evolution of the resin infiltrated WSLs during the fixed orthodontic therapy. This is especially important for patients with long periods of treatment like interdisciplinary orthodontic-orthognathic surgery cases or patients that are refractory to oral hygiene measures.

[An interdisciplinary approach to complex orthodontic-periodontal clinical situations in adult patients]. / O abordare interdisciplinara a unor situatii clinice complexe ortodontico-parodontale la pacientii adulti.

Between orthodontics and periodontology there are many correlations, especially in the treatment of adults with already-damaged periodontal tissues and malocclusions. Aim of this paper was to emphasize that an interdisciplinary periodontal-orthodontic treatment could be beneficial even in a case that seemed hopelessly. A typical case of an adult patient with extensive bone loss due to periodontal disease, occlusal trauma caused by dental malpositions, spacing due to early loss of teeth in the lateral segments and pathologic tooth migration will be presented. The orthodontic treatment was initiated at 3 months after the stabilization of the periodontal therapy and was done with a fixed appliance. During the orthodontic stage periodontal maintenance visits continued at 2-month intervals. The therapy of"black triangles" occurred due to the loss of interdental gingiva was done by stripping followed by a space-closure procedure. A permanent retainer was applied. Benefits and problems of the comprehensive periodontal-orthodontic therapy and treatment protocols will be presented. In conclusion the interdisciplinary therapy of this patient, with a good compliance, was beneficial, improved esthetics, the periodontal status, the ability of the patient to clean the teeth and also led to best position of the abutments for optimal placement of prosthetic reconstructions.
