Use of icdas-ii criteria in the detection of caries lesion in cleft lip and palate patients

Objective:Touse the International Caries Detection and Assessment System (ICDAS-II) to evaluate the scores of different stages of caries lesion development in cleft lip and palate children. Material and Methods:Fifty cleft lip and palate children aged6-10 years atmixed dentition were selected. Two examiners, one after the other, performed the visual examination of dental surfaces. Firstly, the teeth were cleaned with the aid of pumice and water paste. The examination was carried out under the dental chair reflector, after air drying for 5 seconds with air-water syringe, and with the aid of a WHO probe. The sites comprising the sample were classified according to criteria proposed by ICDAS-II. Results:Ten children met the inclusion criteria. Twenty-five anterior teeth at the cleft area and 93 posterior teeth were assessed, totalizing 590 surfaces classified by ICDAS-II. Four hundred and ninety-four surfaces were scored as sound (code 0-0) regarding the Caries Lesion Condition. Only one surface was scored as partial sealant (code 1), according to the Tooth Surface Condition, but classified as sound regarding the Caries Lesion Condition (code 1-0). No surface exhibited stainless steel; porcelain, gold or porcelain fused to metal crowner veneer; lost or broken restoration; and temporary restoration (codes 5, 6, 7, and 8, respectively). Conclusion:ICDAS-II shows good performance in analyzing caries lesions through more specific assessment and more accurate examination, enabling the detection of caries lesion development at several stages

In vivo evaluation of tissue response to new endodontic sealers

Introduction: The sealers can be in direct contact with the periapical tissues. Thus, these materials must have appropriate physical and biological properties, providing conditions for repair to occur. Objective: The aim of this study was to evaluate the response of rat subcutaneous tissue to endodontics sealers. Material and methods: Three materials comprised the groups: group I - Zinc Oxide, Eugenol and Iodoform paste, group II - Portland cement with propylene glycol, and group III - MTA Fillapex® (Angelus). These materials were placed in polyethylene tubes and implanted into dorsal connective tissue of Wistar rats for seven and 15 days. The specimens were stained with hematoxylin and eosin and evaluated regarding to inflammatory reaction parameters through a light microscope. The data were compared using Kruskal-Wallis test with significance level of 5%. The intensity of inflammatory response against the sealers was analyzed by two blinded and previously calibrated observers for all experimental periods. Results: The histological evaluation showed that all the materials caused a moderated inflammatory reaction at seven days which decreased with time. A greater inflammatory reaction was observed at seven days in group I. The other specimens had significantly less inflammatory cells when compared to this group. Tubes with MTA Fillapex® presented some giant cells, macrophages and lymphocytes after seven days. At 15 days, the presence of fibroblasts and collagen fibers was observed indicating normal tissue healing. The group II showed similar results to those observed in MTA Fillapex® already at seven days. At 15 days the inflammatory reaction presented was almost absent at the tissue, with many collagen fibers indicating normal tissue healing. Statistical analysis showed a significant statistical difference amongst the group I (seven days) and II (15 days) (p < 0.05). In the other groups no significant statistical differences were observed. Conclusion: MTA Fillapex® and Portland cement with propylene glycol were more biocompatible than the other tested cements.

Importância dos programas de educação e motivação para saúde bucal em escolas: relato de experiência / Importance of education and motivation programs for oral health in schools: experience report

Atualmente, os esforços da odontologia encontram-se voltados, principalmente, para a prevenção das doenças bucais. Ademais, destaca-se a necessidade de ensinar e motivar hábitos de higiene bucal às crianças. Os métodos de educação e motivação têm a finalidade de esclarecer os pacientes sobre as doenças bucais e mudar seus hábitos de higiene. O objetivo deste trabalho foi o de descrever um programa de educação e motivação para crianças em relação à saúde bucal em escolas. Para o sucesso deste trabalho, as inovações nas atividades propostas no programa dependem da habilidade do profissional. Portanto, o desenvolvimento de programas de educação e motivação para saúde bucal em escolas são indispensáveis para a busca de uma saúde bucal plena.

Nowadays, the eff orts of dentistry aimed mainly at prevention of oral diseases. In addition it's important to teach and encourage oral hygiene to children. The methods of education and motivation are intended to clarify the patients about oral diseases and to change their hygiene habits. The aim of this study was to describe an education and a motivation program for children regarding oral health in schools. In order for this work to succeed, the inovations proposed in the program depend on the professional skills. Therefore, the development of education and motivation programs for oral health in schools is essential to the pursuit of a full oral health.

Efeito do gel de clorexidina em diferentes concentrações no controle do biofilme bacteriano e da inflamação gengival em crianças / Effect of clorexidina in different concentrations in the control on dental plaque and inflammation gingival in children

O presente estudo teve como objetivo avaliar a efetividade da utilização de géis de clorexidina nas concentrações de 0,5%, 1% e 2% para o controle do biofilme dentário e da inflamação gengival em crianças na faixa etária de 7 a 11 anos de idade. A amostra foi composta por 40 crianças, aleatoriamente divididas em quatro grupos: G1 (grupo controle - não utilização de agente químico), G2 (utilização de gel de clorexidina a 0,5%), G3 (utilização de gel de clorexidina a 1%) e G4 (utilização de gel de clorexidina a 2%) para determinação dos índices de placa e gengival. O gel de clorexidina foi aplicado com a utilização de moldeiras descartáveis pré-fabricadas (5 mL), por 1 minuto, uma vez por semana, durante 4 semanas. As avaliações clínicas foram feitas após 1 semana, 1 mês, 3 e 6 meses da última aplicação do gel. Os resultados obtidos foram analisados pela análise de variância a dois critérios, sendo adotado nível de significância igual a 5%. Os índices de placa e gengival reduziram durante o período experimental em todos os grupos. Não houve diferença significante (p <0.05) entre os grupos tratados com gel de clorexidina quando comparado com o grupo placebo na redução de placa e índice gengival. Os resultados mostraram que formulações diferentes de gel de clorexidina não produzem efeito inibidor da placa bacteriana e da inflamação gengival. Sendo assim, estudos adicionais são necessários para esclarecer o papel da clorexidina na prevenção de cárie e doença periodontal em crianças.

The purpose of the present study was to assess the effect of three different formulations of chlorhexidine gel in the concentrations of 0.2%, 1% and 2% for the control of plaque accumulation and gingivitis. This was a double-blind, longitudinal, non-crossover study in 48 children between 7 to 11 years of age. Subjects were randomly assigned to 4 different groups: G 1 (placebo), G 2 (0.2% chlorhexidine gel), G 3 (1% chlorhexidine gel) and G 4 (2% chlorhexidine gel). The chlorhexidine gel was administered once a week during 4 weeks. The clinical evaluations were made after 1 week, 1, 3 and 6 months of the last application of the chlorhexidine gel. Mean plaque and gingival scores were reduced over the four-week trial period for experimental and control groups. There was no significant difference (p<0.05) between the groups treated with chlorhexidine gel when compared with the placebo group in the reduction of plaque and gingival scores. The results indicated that different formulations of chlorhexidine gel did not produce an effective inhibitor of plaque growth. Within the limitations of the present study design, further studies are required to clarify the role of chlorhexidine to prevent caries and periodontal disease.
