|Title:||Comparison Of Periodontal Parameters After The Use Of Orthodontic Multi-stranded Wire Retainers And Modified Retainers [comparação De Parâmetros Periodontais Após Utilização De Contenção Ortodôntica Com Fio Trançado E Contenção Modificada]|
|Abstract:||Objective: To compare two types of fixed orthodontic retainers (a multi-stranded wire retainer and a modified retainer) in relation to established periodontal parameters. The multi-stranded wire retainer is commonly used, and the modified retainer has bends to enable free access of dental floss to interproximal areas. Materials and Methods: For this crossover study, 12 volunteers were selected and used the following retainers for six months: (A) a multi-stranded wire retainer and (B) a modified retainer, both fixed to all anterior lower teeth. After this experimental period, the following evaluations were made: Dental Plaque Index, Gingival Index, Dental Calculus Index and Retainer Wire Calculus Index. The volunteers also responded to a questionnaire about the use, comfort and hygiene of the retainers. Results: The plaque index and the gingival index were higher on the lingual surfaces (p<0.05) for the modified retainer. Furthermore, the calculus index was statistically higher (p<0.05) for the lingual and proximal faces when using the modified retainer. The retainer wire calculus index values were also significantly higher (p<0.05) for the modified retainer. In the questionnaire, 58% of the volunteers considered the modified retainer to be less comfortable and 54% of them preferred the multi-stranded wire retainer. Conclusion: The multi-stranded wire retainer showed better results than the modified retainer according to the periodontal parameters evaluated, as well as providing greater comfort and being the retainer preferred by the volunteers.|
