ABSTRACT

Purpose: The aim of this study was to evaluate gingival abrasion of soft toothbrushes. Material and Methods: This randomized, crossover, blind study tested three commercially available manual soft toothbrushes: CURAPROX® 5460 (CPX), Colgate Slim Soft (COG) and ORAL-B® Indicator 30 Plus (ORB). Fifteen men and 15 women were randomly divided into 3 groups (N=10), who used all the brushes in three consecutive stages of 14 days each. Plaque index (PI), gingival index (GI), and gingival abrasion (GA) were assessed at the end of each experimental stage. Participants were also scored their perception of brush comfort, trauma, and cleanliness with visual analog scales (VAS). Friedman nonparametric test was used to analyze the data (p≤0.05). Results: No statistically significant differences were found among the tested brushes for any of the studied variables. When present, gingival abrasion lesions were mostly small (<2 mm). There was no difference between PI and GI between the 3 brushes. However, in patients' perception, CPX had significantly higher scores for comfort, while COG presented higher scores for trauma and ORB for cleanliness. Conclusion: The results indicate that all the tested brushes were similar concerning gingival abrasion and plaque control. However, patients reported different levels of satisfaction concerning their use. When recommending a soft toothbrush, clinicians should take into consideration individual patient requirements, and provide instructions of use based on the specific characteristics of each brush.

Objetivo: O objetivo deste estudo foi avaliar a abrasão gengival de escovas dentais macias. Material e Métodos: Este estudo randomizado, cruzado e cego testou três escovas manuais macias comercialmente disponíveis: CURAPROX® 5460 (CPX), Colgate® Slim Soft (COG) e ORAL-B® Indicator 30 Plus (ORB). Quinze homens e 15 mulheres foram aleatoriamente divididos em 3 grupos (N = 10), que utilizaram todas as escovas em três estágios consecutivos de 14 dias cada. Índice de placa (IP), índice gengival (IG) e abrasão gengival foram avaliados no final de cada estágio experimental. Os participantes também pontuaram quanto à sua percepção de conforto, trauma e limpeza das escovas com escalas analógicas visuais (EVA). Os dados foram analisados com o teste não paramétrico de Friedman (p≤0,05). Resultados: Não foram encontradas diferenças estatisticamente significativas entre as escovas testadas em relação à abrasão gengival. Quando presentes, as lesões de abrasão gengivais eram em sua maioria pequenas (<2 mm). Não houve diferença entre o IP e IG apresentados pelas 3 escovas. Porém, na percepção dos pacientes, a CPX apresentou escores significativamente maiores para conforto, enquanto a COG apresentou maior trauma e a ORB maior sensação de limpeza. Conclusão: Os resultados indicam que as escovas testadas foram semelhantes quanto à abrasão gengival e controle de placa. No entanto, os pacientes relataram diferentes níveis de satisfação em relação ao seu uso. Ao recomendar uma escova de dentes macia, os dentistas devem levar em consideração os requisitos individuais do paciente e fornecer instruções de uso com base nas características específicas de cada escova.

ABSTRACT

ABSTRACT Introduction: bonded fixed retainers are often used to stabilize the results obtained with the orthodontic treatment. It is important that they do not prejudice dental health, as they will be used for a long period. Objective: The purpose of the present study was to compare periodontal indexes between two types of bonded fixed retainers, conventional 3 x 3 plain retainer (0.8-mm orthodontic wire, bonded to the canines only) and a manufactured braided retainer (0.2 x 0.7-mm stainless steel wire, bonded to all anterior teeth) after use. Methods: a test group of 15 volunteers (aged from 18 to 25 years) used both the conventional retainer and braided retainer for six months. A randomized longitudinal study design, with a two week washout interval, was applied. The dental plaque index, gingival index and dental calculus index were evaluated. Furthermore, the calculus accumulated along the retainer wire was measured and all patients answered a questionnaire about the use, acceptance and comfort of both types of retainers. Results: the scores for plaque and gingival indexes were higher for the braided retainer (p< 0.05) on the lingual and proximal surfaces. The same occurred with the calculus index on the lingual surfaces (p< 0.05). The calculus index along wire was higher for the braided retainer (p< 0.05). All patients preferred the conventional retainer, and said that it was also more comfortable to use. Conclusion: it was concluded that the conventional retainer showed better periodontal indexes than the braided type.


RESUMO Introdução: as contenções ortodônticas fixas são amplamente utilizadas após o tratamento ortodôntico, sendo fundamental que esses dispositivos não se tornem prejudiciais à saúde dentária, já que serão usados por um longo período. Objetivo: o presente estudo teve como objetivo a avaliação periodontal da região da arcada inferior, comparando as condições de acúmulo de placa e cálculo ao longo do fio e na margem gengival, em decorrência do uso da contenção convencional (fio 0,8 mm de aço inoxidável colado apenas nos caninos) ou de uma contenção pré-fabricada com fio trançado (0,2 x 0,7 mm colado em todos os dentes anteroinferiores) após exposição ao meio bucal. Métodos: participaram do estudo 15 voluntários adultos jovens (idades entre 18 e 25 anos) que utilizaram dois tipos de contenções, por seis meses cada. Foi utilizado um modelo de estudo longitudinal, randomizado, com washout de 15 dias. Os parâmetros periodontais utilizados foram: índice gengival, índice de placa e índice de cálculo. O cálculo acumulado ao longo da contenção foi avaliado e todos os pacientes responderam a um questionário sobre o uso, aceitação e conforto de ambos os tipos de contenção. Resultados: observou-se que o índice de placa foi maior para a contenção com fio trançado (p<0,05), assim como o índice gengival (p<0,05). O mesmo ocorreu para o índice de cálculo nas faces proximais e lingual (p<0,05). O índice de cálculo ao longo do fio também foi significativamente maior para a contenção com fio trançado (p<0,05). Em relação ao questionário aplicado, 60% dos voluntários consideraram que a contenção com fio trançado foi mais desconfortável, e todos eles preferiram a contenção convencional. Conclusão: concluiu-se que a contenção convencional apresentou melhores resultados periodontais, quando comparada à contenção pré-fabricada com fio trançado.

ABSTRACT

OBJECTIVES: The aim of this study was to analyze the periodontal parameters of patients with chronic renal failure. MATERIAL AND METHODS: The periodontal status of 16 Brazilian patients aged 29 to 53 (41.7±7.2) years with chronic renal failure (CRF) and another matched group of 14 healthy controls with periodontitis was assessed clinically and microbiologically. Probing pocket depth (PPD), gingival recession (GR), dental plaque index (PLI), gingival index (GI), and dental calculus index (CI) were the clinical parameters recorded for the entire dentition (at least 19 teeth), while the anaerobic periodontopathogen colonization in four sites with the highest PPD was evaluated using the BANA test ("PerioScan"; Oral B). RESULTS: The results for the CRF group and control group, respectively were: PPD: 1.77±0.32 and 2.65±0.53; GR: 0.58±0.56 and 0.51±0.36; PLI: 1.64±0.56 and 1.24±0.67; GI: 0.64±0.42 and 0.93±0.50; CI: 1.17±0.54 and 0.87±0.52. Comparison between groups using the "t" test revealed a significantly increased PPD (p<0.001) in the control group. Comparison of the other clincial parameters by the Mann-Whitney test showed differences only for PLI, which was significantly higher (p<0.05) in the CRF group. Spearman's test applied to each group showed a positive correlation among all clinical parameters, except for GR (p<0.05). None of the groups showed any correlation between GR and GI, while a significant negative correlation between GR and PPD was observed for the CRF group. The percentage of BANA-positive sites was 35.9 percent for the CRF group and 35.7 percent for the control group. The BANA test correlated positively with PPD only in the control group and with GR only in the CRF group. CONCLUSIONS: In spite of a higher PLI and dense anaerobic microbial population even in shallow PPD, patients with CRF exhibited better periodontal conditions than periodontitis patients, which is an evidence of altered response to local irritants.
