Albright hereditary osteodystrophy: dental management case report / Osteodistrofia hereditária de albright: relato de caso de manejo 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.

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.

Efficacy of two mouthwashes with cetylpyridinium chloride: a controlled randomized clinical trial

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.

Efficacy of two soft-bristle toothbrushes in plaque removal: a randomized controlled trial

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.
