Resumo
O objetivo deste estudo foi avaliar os parâmetros clínicos e microbiológicos periodontais de crianças e adolescentes sob terapia ortodôntica com aparelho fixo ou removíveis. Trinta indivíduos (14,5l1,7 anos - Grupo FIX) que utilizavam aparelhos fixos e 18 que utilizavam aparelho extra bucal removível ou placa de Hawley há pelo menos 6 meses (9,6 l 1,5 anos - Grupo REM) foram comparados a dois grupos controle, constituídos por indivíduos da mesma idade (14,2 l 1,7 anos - Grupo C-FIX e 9,3 l 1,9 anos - Grupo C-REM) que não utlizavam esses dispositivos. Foi analisada a presença de placa bacteriana visível (IP), sangramento gengival (IG), profundidade de sondagem (PS) e perda de inserção clínica (PIC). Amostras de placa bacteriana subgengival foram coletadas e analisadas por meio de sondas de oligonucleotídeos para A. actinomycetemcomitans (Aa), C. rectus, Capnocytophaga sp. E. corrodens, F. nucleatum, F. vincentii, M. micros, Neisseriaceae., P. gingivalis, P. intermedia, espiroquetas, T. forsythensis e Treponema sp. Diferenças significantes (p<0,05) foram observadas entre os grupos FIX e C-FIX quanto aos parâmetros IP (66,8% e 47,7%), IG (43% e 15,6%), e para as prevalências de todas as bactérias avaliadas, exceto as da familia Neisseriaceae. Entre dentes bandados e seus análogos no grupo controle foram encontradas diferenças significantes para os parâmetros PV (80,3% e 58,8%), SM (64,3% e 20,6%) e PS (2,9 mm e 2,5 mm), respectivamente. Entre os grupos REM e C-REM, essas diferenças também foram observadas para IP (58,7% e 14,3%) e IG (19,8% e 8,8%) e para as prevalências de Aa, C. rectus, E. corrodens, Neisseriaceae e espiroquetas. Entre os dentes retentores de grampo e seus análogos no grupo controle verificou-se diferenças significantes para IP (77,8% e 31,3%). Não foi verificado aumento da PS associado a PIC. Também foi avaliada a... .
The purpose of this study was to compare clinical and microbiological parameters in children and adolescents with and without fixed or removable orthodontic appliances. Thirty subjects (mean age 14.5l1.7 years) treated with fixed appliances and 18 treated with removable appliances for at least 6 months were selected as test groups, FIX and REM, respectively. The control groups were comprised of 30 subjects (mean age 14.2l1.7 years - Group C-FIX) and 18 subjects (mean age 9.3l1.9 years - Group C-REM) that did not receive orthodontic treatment. Clinical evaluations were made for plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment loss (CAL). Subgingival plaque samples were collected from the patients and analyzed by oligonucleotide probes for the presence of A. actinomycetemcomitans (Aa), C. rectus, Capnocytophaga sp. E. corrodens, F. nucleatum, F. vincentii, M. micros, Neisseriaceae., P. gingivalis, P. intermedia, spirochetes, T. forsythensis and Treponema sp. Additionally, two subgingival dental plaque samples from one subject of each test group were further analyzed by cloning and sequencing the amplified 16S rDNA. Significant differences were noted between FIX and C-FIX for PI (66.8% versus 47.7%), GI (43.8% versus 15.6%) and between the banded teeth in the FIX group and the analogous teeth in the C-FIX group for PI (80.3% versus 58.8%), GI (64.3% versus 20.6%) and PD (2.9 mm versus 2.5 mm). Significant differences were noted between FIX and C-FIX for all targeted bacteria but Neisseriaceae. Results: Significant differences were also noted between REM and C-REM for PI (58.7% versus 14.3%) and GI (19.8% versus 8.8%) and between the clasped teeth in the test group and the analogous teeth in the control group for PI (77.8% versus 31.3%). Significant differences were noted between the REM and C-REM for Aa... (Complete abstract, click electronic address below).
