RESUMO O objetivo desse ensaio clínico, examinador-cego, randomizado e controle foi de comparadas a eficácia de duas escovas de cerdas macias em relagäo ao controle de placa. Setenta vo-luntários foram randomicamente alocados para Grupo A (es-cova com ponta cónica) ou Grupo B (escova com ponta arredondada). Na consulta inicial (dia 0), voluntarios receberam exame de placa utilizando o Índice de identificagäo de placa melhorado. Sob supervisäo, eles escovaram seus dentes por 1 minuto com as escovas designadas e o exame de placa foi repetido. Voluntarios continuaram seu regime de higiene oral (escova dental alocada e dentifrício comum fornecidos pelos pesquisadores) durante 7 dias. Os procedimentos da consulta inicial foram novamente repetidos. Análises estatísticas distintas foram realizadas para percentual de redugäo média de placa para os escores de boca toda, interproximal e linha gengi-val em ambos os momentos, utilizando teste de Mann-Whitney, p<0,05. Após único uso da escova, no dia 0, o percentual de redugäo média de placa foi significativamente reduzido em ambos os grupos (p<0,05), com reduções significativas para boca toda (21,39±12,44 vs. 11,40±11,17), linha gengival (6,32±7,37 vs. 2,89±4,57) e interproximal (10,82±10,49 vs. 5,21±7,68) no Grupo A quando comparada com o Grupo B. Entretanto, no dia 7, nenhuma diferenga significativa foi observada entre os grupos para boca toda (29,94±20,91 vs. 26,58±18,64), linha gengival (14,04±18,82 vs. 13,78±17,63) e interproximal (26,41±22,77 vs. 23,12±20,98) (p>0,05). Em conclusäo, no dia 0, a escova do Grupo A apresentou eficácia superior na remo-gäo de placa suprageng ival quando comparada com a escova do Grupo B, como demonstrado nos escores de placa de boca toda, linha gengival e interproximal.

ABSTRACT The aim of the present examiner-blind randomized controlled clinical study was to compare the efficacy two soft-bristle toothbrushes in terms of plaque removal. Seventy volunteers were randomly allocated to Group A (tapered-tip toothbrush) or Group B (end-rounded toothbrush). At baseline appointment (Day 0), volunteers underwent plaque examination using the Improved Plaque Identification Index. Under supervision, they brushed their teeth for 1 minute with their assigned toothbrushes and the plaque examination was repeated. Volunteers continued the oral hygiene regimen (assigned toothbrush and a regular dentifrice provided by the researchers) for 7 days. The experimental procedures of Day 0 were then repeated. Separate statistical analyses were performed for mean percent reduction of plaque in the whole-mouth, interproximal and gumline scores at both times, usingMann-Whitney test, p<0.05. After a single toothbrushing, on Day 0, mean percent plaque was significantly reduced in both groups (p<0.05), with statistically greater reductions of whole-mouth (21.39±12.44 vs. 11.40±11.17), gumline (6.32±7.37 vs. 2.89±4.57) and interproximal (10.82±10.49 vs. 5.21±7.68) for Group A as compared to Group B. However, on day 7, no significant difference was observed between groups for whole-mouth (29.94±20.91 vs. 26.58±18.64), gymline (14.04±18.82 vs. 13.78±17.63) and interproximal surfaces (26.41±22.77vs. 23.12±20.98) (p>0.05). In conclusion, on Day 0, Group A presented higher efficacy in supragingival plaque removal than Group B, as reflected by whole-mouth, gumline and interproximal plaque scores.

RESUMO A Osteodistrofia Hereditária de Albrighth é uma alteração que compreende características fenotípicas de origem genética, tais como baixa estatura, obesidade e braquidactília. É uma desordem rara e está relacionada com o pseudo-hipoparatireoidismo. No âmbito da Odontologia pode estar associada à hipoplasia de esmalte e erupção tardia dos dentes. Além disto em função de problemas neurológicos estes pacientes podem impor dificuldades de comportamento no momento do atendimento. O presente estudo objetivou descrever um caso clínico de uma paciente, com o possível diagnóstico de Osteodistrofia Hereditária de Albright, apresentando sintomas e limitações ao tratamento odontológico.

ABSTRACT Albright hereditary osteodystrophy is a disorder comprising phenotypic characteristics of genetic origin, such as short stature, obesity, and brachydactyly. It is a rare disorder and is related to pseudohypoparathyroidism. Within dentistry, it may be associated with enamel hypoplasia and late eruption. Furthermore, due to neurological problems, these patients may impose behavioural difficulties during dental appointments. The present study aims to describe the case of a patient with a possible diagnosis of Albright hereditary osteodystrophy, presenting symptoms and limitations to dental management.

Abstract This study aimed to evaluate the anti-plaque and anti-gingivitis effects of two mouthwashes containing cetylpyridinium chloride (CPC), in comparison to negative control mouthwash. One hundred and twenty subjects were randomly assigned to study groups: test (0.075% CPC and 0.28% zinc lactate), positive control (0.07% CPC) and negative control mouthwash without CPC. All volunteers were examined by a calibrated examiner for the Quigley-Hein Plaque Index (Turesky modification) and Löe-Silness Gingival Index (GI). Gingival severity was also measured by the percentage of sites with positive gingival bleeding. During six weeks, oral hygiene consisted of brushing twice daily with a toothbrush and toothpaste and rising with their assigned mouthwash. Plaque and gingival parameters were assessed at baseline, after four and six weeks of product use. Statistical analyses were performed separately for plaque and gingival indices, by ANOVA, paired t-test and ANCOVA (α < 0.05). After 4 and 6 weeks, all mouthwashes groups presented statistically significant reductions in plaque and gingival parameters as compared to baseline. In comparison to the positive control, the test group presented additional reductions in dental plaque of 19.8% and 16.8%, after 4 and 6 weeks, respectively. For GI, the additional reductions in the test group were 9.7% and 14.3%, at 4 and 6 weeks, respectively. The test group showed additional reduction of 35.3% and 54.5% in the gingival severity, at week 4 and 6, respectively. It is concluded that the mouthwash containing CPC and zinc lactate presents significant anti-plaque and anti-gingivitis effects as compared to positive and negative control mouthwashes.

Abstract The aim of this study was to compare the efficacy in supragingival plaque removal of two soft-bristle toothbrushes. Seventy volunteers were allocated randomly to the Colgate Slim Soft or Curaprox CS5460 toothbrush grourps. At baseline appointment, volunteers underwent plaque examination using the Rustogi Modification of the Navy Plaque Index. Under supervision, they then brushed their teeth for 1minute with their assigned toothbrushes and the plaque examination was repeated. Volunteers performed daily oral hygiene with their assigned toothbrush and a regular dentifrice provided by the researchers for 7 days. The baseline experimental procedures were then repeated. Separate analyses of variance were performed for the whole-mouth, interproximal, and gumline plaque scores (p < 0.05). No difference in baseline pre-brushing scores was found between groups. After a single toothbrushing, the mean plaque score was significantly reduced in both groups (p < 0.05), with greater reduction of whole-mouth and interproximal plaque scores observed in the SlimSoft group compared with the Curaprox group (p < 0.05). After 7 days, the SlimSoft group showed greater reduction of the whole-mouth and interproximal plaque scores compared with the Curaprox group (p < 0.05). In conclusion, the SlimSoft toothbrush presented greater efficacy in supragingival plaque removal than did the Curaprox CS5460 toothbrush, as reflected by whole-mouth and interproximal plaque scores.
