RESUMO

Oral health problems can influence people's Quality of Life (QoL) because of pain, discomfort, limitations, and other esthetics problems, affecting their social life, feeding, daily activities, and the individual's well-being. To compare oral health-related quality of life (OHRQoL) of children with and without oral clefts and their families. 121 children aged from 2 to 6 years, from both sexes, enrolled in the treatment routine of the Pediatric Dentistry Clinics of a Dental School and a Hospital for Cleft Treatment were divided into two groups: Group 1 - children with cleft lip and palate; Group 2 - children without cleft lip and palate. The OHRQoL was assessed using the validated Portuguese version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). The questionnaire was answered individually, only once, at a private place. Mann-Whitney U test was used to verify differences between groups. Spearman's Rho test was used to associate sex and age with quality of life. The level of significance was set at 5% (p<0.05). According to the parents' perception on the OHRQoL of children with and without cleft lip and palate, oral health of children with oral clefts (Group 1) had a statistically significant impact on OHRQoL. The correlation of sex with impact on OHRQoL did not show statistically significant differences. On the other hand, the higher the age the higher the impact on QoL. The group comparison revealed that the cleft lip and palate negatively impacted on OHRQoL of 2 to 6-year-old children and their parents.

RESUMO

INTRODUCTION: Dental enamel defects (DEDs) are faulty or deficient enamel formations of primary and permanent teeth. Changes during tooth development result in hypoplasia (a quantitative defect) and/or hypomineralisation (a qualitative defect). OBJECTIVE: To compare technology-based diagnostic methods for detecting DEDs. MATERIAL AND METHODS: Two-hundred and nine dental surfaces of anterior permanent teeth were selected in patients, 6-11 years of age, with cleft lip with/without cleft palate. First, a conventional clinical examination was conducted according to the modified Developmental Defects of Enamel Index (DDE Index). Dental surfaces were evaluated using an operating microscope and a fluorescence-based device. Interexaminer reproducibility was determined using the kappa test. To compare groups, McNemar's test was used. Cramer's V test was used for comparing the distribution of index codes obtained after classification of all dental surfaces. RESULTS: Cramer's V test revealed statistically significant differences (P < .0001) in the distribution of index codes obtained using the different methods; the coefficients were 0.365 for conventional clinical examination versus fluorescence, 0.961 for conventional clinical examination versus operating microscope and 0.358 for operating microscope versus fluorescence. The sensitivity of the operating microscope and fluorescence method was statistically significant (P = .008 and P < .0001, respectively). Otherwise, the results did not show statistically significant differences in accuracy and specificity for either the operating microscope or the fluorescence methods. CONCLUSION: This study suggests that the operating microscope performed better than the fluorescence-based device and could be an auxiliary method for the detection of DEDs.

RESUMO

This in vitro study evaluated the impact of initial erosion on the susceptibility of enamel to further erosive challenge. Thirty bovine enamel blocks were selected by surface hardness and randomized into two groups (n = 15): GC- group composed by enamel blocks without erosion lesion and GT- group composed by enamel blocks with initial erosion lesion. The baseline profile of each block was determined using the profilometer. The initial erosion was produced by immersing the blocks into HCl 0.01 M, pH 2.3 for 30 seconds, under stirring. The erosive cycling consisted of blocks immersion in hydrochloric acid (0.01 M, pH 2.3) for 2 minutes, followed by immersion in artificial saliva for 120 minutes. This procedure was repeated 4 times a day for 5 days, and the blocks were kept in artificial saliva overnight. After erosive cycling, final profile measurement was performed. Profilometry measured the enamel loss by the superposition of initial and final profiles. Data were analyzed by t-test (p<0.05). The result showed no statistically significant difference between groups (GS = 14.60±2.86 and GE = .14.69±2.21 µm). The presence of initial erosion on bovine dental enamel does not enhance its susceptibility to new erosive challenges.

RESUMO

The application of resin-based materials is an alternative of treatment for eroded lesions. Nevertheless, there are no studies about the penetration of these materials into eroded lesion, which might affect its adhesion. Therefore, this study evaluated the penetration of four resin-based materials, with and without enamel etching. By using an in vitro protocol, types of treatment were studied at five levels (AdheSE(®) , Tetric N-Bond(®) , Single Bond 2(®) , Helioseal Clear(®) , Icon(®) ) and types of enamel etching in two levels (with and without). Materials were stained with 0.02 mg/mL ethanolic solution of tetramethylrhodamine isothiocyanate. Bovine enamel samples (4 × 4 mm) were immersed in 0.01 M HCl, pH 2.3, for 30 seconds to produce initial eroded lesions. Afterward, the materials were applied on half of sample enamel surface following the manufacturer's instructions. On the other half of sample, the materials were applied without etching the enamel. Materials penetration into the enamel was assessed by Confocal Laser Scanning Microscopy on reflection and fluorescence modes. The penetration depth (PD) was measured using ImageJ software. Data were analyzed by two-way ANOVA and Tukey test (P < 0.05). Regardless of the material, etched enamel resulted in higher PD than non-etched (P < 0.05). Icon(®) showed the highest PD in enamel followed by Helioseal Clear(®) (P < 0.05), with significant difference between them (P < 0.05) and no difference was found among AdheSE(®) , Tetric N-Bond(®) , and Single Bond 2(®) (P > 0.05). It can be concluded that prior enamel etching increased the materials penetration into eroded enamel and the Icon(®) -infiltrant presented highest penetration.

RESUMO

A associação entre amamentação materna e cárie dentária é controversa. O presente estudo avaliou a experiência de cárie dentária entre bebês exclusivamente amamentados pelo seio materno ou pelo uso complementar de métodos artificiais auxiliares. Dados demográficos, valores do índice ceod, tempo de aleitamento materno e diagnóstico de hábitos bucais deletérios de sucção foram coletados dos prontuários clínicos-odontológicos de 299 bebês. Valores de P < 0,05 foram considerados para diferenças estatisticamente significantes. Os resultados demonstraram um significativo aumento da experiência de cárie dentária entre os bebês amamentados exclusivamente pelo seio materno. A média do tempo de aleitamento materno foi maior entre bebês com diagnóstico de cárie precoce da infância (CPI) (14,7±8,7 meses) quando comparado com bebês sem diagnóstico de CPI (8,3±6,8 meses) (P<0,001). Entretanto, bebês que desenvolveram hábitos bucais deletérios foram amamentados por menos tempo. O aleitamento materno deve ser estimulado, pois é capaz de prevenir infecções, mortalidade infantil, respiração bucal e hábitos bucais deletérios, além de favorecer o estabelecimento do vínculo emocional entre mãe e flho. Entretanto, o maior risco de lesões de cárie dentária deve determinar atenção especial da equipe de saúde da família em relação à manutenção das condições adequadas da saúde bucal dos bebês

The association between breastfeeding and dental caries is controversial. This study aimed to evaluate the experience of dental caries among exclusively breastfed infants and non-exclusively breastfed infants. Demographic data, dmft index scores, breastfeeding duration, and diagnosis of deleterious oral sucking habits were collected from 299 patient records of the Clinic of Babies of Cuiabá School of Dentistry. Statistical differences were considered to be signifcant with P values < 0.05. The results demonstrated a signifcant increase of experience of dental caries among exclusively breastfed infants. The mean of breastfeeding duration in infants with early childhood caries (ECC) diagnosis (14,7±8,7 months) was higher than those infants without ECC diagnosis (8,3±6,8 months) (P<0,001). The breastfeeding needs to be continuously estimulated because it prevents infections, infant mortality, oral breathing, deleterious oral sucking habits, besides favoring the maternal bonding. Higher risks of dental caries lesions among infants breastfed for longer, however, must lead family health teams to a special focus on the maintenance of good conditions of infants' oral health

RESUMO

Objetivo: Comparar o exame visual-tátil com os exames baseados em tecnologia na detecção de lesões de cárie em crianças com fissuras labiopalatina. Material e Métodos: 405 faces mesial, distal, vestibular e palatina dos dentes permanentes anteriores superiores próximos a área da fissura de 95 crianças com idade entre 6-12 anos (média 10 anos± 2 anos e 9 meses) foram avaliadas por dois examinadores previamente calibrados. Os seguintes métodos de detecção de lesão de cárie foram usados: exame visual-tátil (Método 1), exame visual-tátil com o auxílio do microscópio operatório (Método 2), exame visual por meio de um aparelho de fluorescência por LED (Método 3). ICDAS foi o sistema usado para classificar todas as lesões de cárie nos três métodos. A sonda OMS foi usada durante o exame visual-táctil. O microscópio operatório foi usado em magnificação de 10x. O aparelho de fluorescência por LED (Evince ®) tinha uma câmera ligada à peça de mão e conectada ao computador. Os métodos auxiliares de detecção de cárie foram comparados ao exame visual-táctil pelo teste de Friedman (P < 0,05). Resultados: Não houve diferença estatisticamente significante na eficácia dos métodos de detecção de lesão de cárie (P = 0,786). Conclusão: O microscópio operatório e o aparelho de fluorescência por LED não mostraram diferença na a detecção de lesão de cárie para avaliar dentes próximos à área da fissura labiopalatina.

Objective: To compare the visual-tactile examination with the technology-based caries detection examinations in children. Material and Methods: Two previously calibrated examiners assessed 405 mesial, distal, labial, and palatal surfaces of the upper anterior permanent teeth next to the cleft area of 95 children aged 6 to 12 years (mean age of 10 years ± 2 years and 9 months) with oral clefts but without the presence of any associated syndrome or craniofacial anomaly. The following detection methods were used: visual-tactile examination (Method 1), visual-tactile examination through operating microscope (Method 2), visual examination through LED-based fluorescence device (Method 3). ICDAS was the system used to score all caries lesions for all methods. WHO probe was used during the examination with visual-tactile examination. Operating microscope was used at x10 magnification. LED-based fluorescence (Evince™) had a video camera coupled to the handpiece and linked to a computer. The adjunct caries detection methods were compared to visual-tactile examination by Friedman test (P < 0.05). Results: The efficacy of carious lesion detection methods were statistically similar (P = 0.786). Conclusion: Both the operating microscope and the LED-based fluorescence device did not improve caries lesion detection in the permanent anterior teeth next to the cleft area.

RESUMO

Ectodermal dysplasia is a rare congenital disease that affects several structures of ectodermal origin. The most commonly related oral characteristics are hypodontia, malformed teeth and underdeveloped alveolar ridges. New alternative treatments are needed due to the failure of the conventional prosthesis retention. This case report outlines the oral rehabilitation treatment of a 9-year-old girl with ectodermal dysplasia. The treatment was performed with conventional prosthesis upon mini-implants. The mini-implants provided prosthetic retention. The patient reported a good adaptation of the dental prosthesis and satisfaction with the treatment. The increased self-esteem improved the socialization skills of the girl. In this case report, use of prosthesis with mini-implants was satisfactory for prosthetic retention. However, clinical studies with long-term follow-up are needed to test the mini-implants as an alternative for oral rehabilitation of children with ectodermal dysplasia.

A displasia ectodérmica é uma doença congênita rara, que afeta várias estruturas de origem ectodérmica. As principais características na cavidade oral são hipodontia, má formação dentária e subdesenvolvimento do rebordo alveolar. Devido às falhas de retenção das próteses convencionais, novas alternativas de tratamento são necessárias. Este relato de caso descreve o tratamento de reabilitação oral em uma menina de 9 anos de idade com displasia ectodérmica. O tratamento foi realizado com próteses dentárias convencionais sobre mini-implantes. Os mini-implantes promoveram a retenção da prótese. A paciente relatou uma boa adaptação das próteses e satisfação com o tratamento. O aumento da autoestima melhorou as atividades de socialização da criança. Neste estudo de caso, o uso de prótese com mini-implantes foi satisfatória para a retenção da prótese. No entanto, estudos clínicos longitudinais são necessários para testar os mini-implantes como uma alternativa para a reabilitação oral de crianças com displasia ectodérmica.

RESUMO

Inúmeros estudos trazem o bruxismo como tema central, relacionando-o com vários distúrbios, tais como problemas dentários, problemas do sono, dores de cabeça e nos músculos da face. Para compreendermos profundamente essa atividade muscular que o bruxismo provoca, temos que compreender seus fatores etiológicos. Porém, o bruxismo é multifatorial e alguns estudos têm demonstrado quais fatores estão comumente associados a ele. O objetivo deste trabalho é realizar uma revisão de literatura, analisando quais fatores etiológicos são mais comumente citados em estudos sobre o bruxismo do sono

Studies having bruxism as main theme relate it to many disturbs, such as dental problems, sleep problems, headaches and facial muscle pain. The etiology is important to deeply understand the muscular activities originated by the bruxism. However, bruxism is multifactorial and some common factors are often associated. The purpose of this study is to make a literature review that analyzes which etiological factors are more often reported in sleep bruxism studies
