          Abstract

          Introducción. El objetivo fue evaluar la eficacia del JAL 90458 sobre el recrecimiento de placa en pacientes con aparatología fija "multibrackets". Material y métodos. Participaron 16 sujetos (11 mujeres y 5 hombres) entre 12 a 39 años de edad. El estudio fue realizado bajo condiciones de un ensayo clínico, aleatorizado, doble ciego y paralelo de grupos balanceados usando un diseño de recrecimiento de placa. Los sujetos recibieron una profilaxis oral y suspendieron toda medida de higiene oral por los siguientes 4 días, usando sólo el gel asignado. Se evaluó el Índice de placa de Quigley-Hein modificado por Turesky (IPQH-T), el Índice de placa bracket (IPb) y el Índice de Sangrado al Sondaje (ISS). Para el análisis de datos se utilizó el test de la t de Student para muestras independientes, el test exacto de Fisher y el coeficiente de correlación de Pearson. Resultados. Se obtuvieron diferencias estadísticamente significativa entre el JAL 90458 y el gel control en el IPQH-T (2,52±0,57 vs 1,78±0,79, p<0,05), así como en el IPb (2,04±0,73 vs 1,27±0,59, p<0,05), y ISS (1,24±0,20 vs 0,48±0,24, p<0,05). Hubo una alta correlación entre el IPb y el IPQH-T (r=0,94, p<0,01). La ecuación de regresión lineal para predecir el valor del IPQH-T a través del IPb fue: IPQH-T=0,568+0,956 * IPb. Discusión. La aplicación del JAL 90458 en pacientes con aparatos fijos "multibrackets" demostró ser eficaz en la disminución del recrecimiento de placa bacteriana. No se detectó ningún efecto secundario clínico relevante.

          Introduction. The objective was test the efficacy of JAL 90458 on the regrowth of plaque in patients with orthodontic braces. Material and methods. A total of 16 subjects (11 women and 5 men) between the ages of 12 and 39 took part in this study. The study was conducted under clinical trial conditions, double blind, parallel and randomized in balanced groups using a plaque regrowth design. The subjects had a professional teeth-cleaning and were instructed to not use any kind of oral hygiene measures for the next four days, using only the gel that had been assigned to them. We took into account the following parameters: the Quigley - Hein plaque index, modified by Turesky (QHPI-T), Plaque-Bracket Index (PIb) and the Bleeding on Probing Index (BOP). Analysis of the data was done using a Student´s t-test, Fisher´s exact test and Pearson´s correlation coefficient. Results. Statistically significant differences between the JAL 90458 group and the control gel group were obtained in the QHPI-T (2.52±0.57 vs 1.78±0.79, p<0.05), as well as in the PIb (2.04±0.73 vs 1.27±0.59, p<0.05), and BOP (1.24±0.20 vs 0.48±0.24, p<0.05). There was a high correlation between the PIb and the QHPI-T (r=0.87, p<0.01). The linear regression equation to predict the value of the QHPI-T using the PIb was: QHPI-T=0.568+0.956 * PIb. Discussion. The application of JAL 90458 in patients with orthodontic braces was shown to be effective in the diminishing the regrowth of bacterial plaque. We did not detect any clinically relevant side effect.

            Clinical and microbiological effects of fixed orthodontic appliances on periodontal tissues in adolescents.

            To determine the effects of fixed orthodontic appliances on periodontal health and microbiological composition of subgingival dental plaque. This prospective longitudinal self-controlled study was conducted on 32 adolescents (13 males, 19 females), who were scheduled for fixed orthodontic treatment between 2002 and 2005. Dental plaque accumulation, gingival inflammation and pocket probing depth were measured at the mesio-vestibular angle of the examined group of teeth followed by collection of subgingival dental plaque samples in the same points. These periodontal indices and microbiological parameters were determined prior to the placement of fixed appliances and 1, 3 and 6 months after the beginning of orthodontic treatment. All values of both clinical and microbiological parameters started to increase after the placement of fixed appliances. Maximum values were reached 3 months after fixed appliance placement followed by their decrease in the last registration period of 6 months after the placement of fixed appliances. Treatment with fixed appliances in adolescents may transitionally increase the values of all periodontal indices and stimulate the growth of periodontopathogenic bacteria, but without destructive effects on deep periodontal tissues.

              Chlorhexidine compared with other locally delivered antimicrobials. A short review.

              Based on the association of bacterial plaque with the initiation of chronic gingivitis and progression of chronic periodontitis, chemical antiplaque agents have been employed both in prevention of periodontal disease and its treatment. In supragingival plaque control regimens, chlorhexidine has not been superceded as a chemical anti-plaque agent, although other compounds have been shown to be useful. The local side-effects of chlorhexidine and other cationic antiseptics, however, limit their long-term use for prevention. Extrinsic tooth staining in particular remains the greatest problem. Short-term anti-plaque uses for chlorhexidine include as an adjunct to mechanical cleaning in the initial oral hygiene phase of treatment, in situations where mechanical oral hygiene is difficult, including postsurgery, intermaxillary fixation, fixed orthodontic therapy, physically and mentally handicapped individuals, systemic diseases with oral manifestations such as leukaemia. More recent interest in chlorhexidine has resulted from the delivery of compounds subgingivally in the treatment of chronic periodontitis. Such methods have extended the use of chlorhexidine into areas inaccessible to the action of antimicrobial drugs delivered locally by conventional means, such as tooth brushing or mouth rinsing. Available evidence suggests that chlorhexidine may not be as effective as some antimicrobial drugs whose activity is more specific for those organisms considered particularly pathogenic to the periodontal tissues.
