RESUMO

The aim of this study was to assess the performance of dental students for detecting in vitro occlusal carious lesions using the International Caries Detection and Assessment System (ICDAS) with different learning strategies. A convenience sample of all 64 fourth-year dental students at a dental school in Brazil who had no previous experience with ICDAS was selected for the study in 2015. First, students performed the in vitro examination of the occlusal surfaces of 80 teeth according to ICDAS. Two weeks later, students were randomly allocated to three groups: G1 (n=21), ICDAS e-learning; G2 (n=22), ICDAS e-learning + digital learning tool (DLT); G3 (n=21), no training (control group). All students reexamined the 80 teeth according to ICDAS two weeks later. Sensitivity, specificity, and area under the ROC curve (AUC) were calculated according to three thresholds. Of the 64 students, 59 completed all study phases, for a 92.2% participation rate. The intra-group comparison found significantly higher sensitivity and specificity values for G1 and G2 students. G3 students showed an increased sensitivity at the D2 threshold. G2 was the only training strategy that resulted in significant improvement for the AUC. In the comparison of groups at the same threshold, G1 showed higher specificity at D3 threshold (0.78) than G2 (0.72) and G3 (0.73). Regarding sensitivity, G1 showed a lower value at D2 (0.91) threshold than G2 (0.94) and G3 (0.94). In this study, both training strategies (ICDAS e-learning and ICDAS e-learning + DLT) improved the performance of dental students for the in vitro detection of occlusal carious lesions, mainly when the association of methods was used.

RESUMO

Purpose: The purpose of this systematic review and meta-analysis was to assess the impact of dental caries on the oral health-related quality of life (OHRQoL) of preschool children. Methods: A literature search was undertaken through PubMed/MEDLINE, Scopus, and TRIP databases to verify available studies about the topic. Two reviewers independently selected the studies, extracted the data, and assessed the bias risk. Global meta-analysis was carried out comparing means and standard deviations of the OHRQoL overall score from preschool children with and without caries. Subgroup analysis was conducted using different cutoff points for caries: decayed, missing, or filled teeth (dmft) greater than or equal to one and greater than or equal to six. Results: From 597 potentially eligible studies, 63 were selected for full-text analysis and 29 were included in the review: 12 for quantitative analysis and 17 for qualitative analysis. Most studies were conducted in Brazil; Early Childhood Oral Health Impact Scale (ECOHIS) was the instrument used in most studies to evaluate OHRQoL. A dmft index at least of one was sufficient to negatively impact the OHRQoL of preschool children, although a higher cutoff point for caries augmented the difference between groups. Bias risk was low. Conclusions: Caries might be associated with negative impact on the oral health-related quality of life of preschool children, and this association tends to increase as the disease severity worsens.

RESUMO

O aumento na ocorrência de fluorose dentária, observado nos últimos anos, tende a promover maior procura pela resolução estética dos manchamentos, o que é geralmente feito com a aplicação de técnicas de erosão-abrasão. Pode-se supor que a abrasão fisiológica e a erosão ácida que ocorrem ao longo da vida atuem no sentido de atenuar a severidade das manchas de fluorose. O presente artigo apresenta um caso de atenuação de manchamentos por fluorose dentária nos dentes anteriores de um paciente de 36 anos que aos 15 havia recebido tratamento erosivo-abrasivo apenas em seus incisivos 11 e 21. Isso permitiu que, após duas décadas, fosse possível comparar os dentes tratados com aqueles que sofreram apenas desgaste fisiológico e a constatação de que, embora as manchas ainda permaneçam, o aspecto de ambos é estético e socialmente aceitável.


The increased prevalence of dental fluorosis observed in recent years tends to promote an increased demand for esthetic resolution of tooth staining, which is usually made by erosion-abrasion techniques. It can be assumed that the physiological abrasion and acid erosion that occur throughout life act to mitigate the severity of fluorosis. This article presents a case of mitigation of fluorosis stains in the anterior teeth of a 36-year-old patient who had received, at 15 years, erosive/abrasive treatment only on his incisors 11 and 21. After two decades, it was possible to compare the treated teeth with those who suffered only physiological wear. It was possible to find that in spite the stains were still present, their clinical aspect is esthetic and socially acceptable.

RESUMO

INTRODUÇÃO: A resina composta é um material versátil em Odontologia Estética, principalmente por suas propriedades ópticas, dentre as quais a fluorescência. Poucos são os estudos que avaliaram esta propriedade e a comparação dos resultados encontrados torna-se difícil em função da inexistência de padronização nas metodologias na confecção e na armazenagem dos corpos de prova. OBJETIVO: Verificar a influência do polimento superficial e do meio de armazenagem, em estudos in vitro, em que se avalia a propriedade óptica de fluorescência em resinas compostas. MATERIAL E MÉTODO: Foram preparados 70 corpos de prova circulares (10 mm × 2 mm ) com resina composta microhíbrida (Opallis,- A2E - FGM.) Os meios de armazenagem foram: água deionizada, água da torneira e saliva artificial. Os protocolos de polimento superficial, realizados em politriz após a obtenção dos corpos de prova, utilizaram lixas de granulações 600, 1200 e 2500. Os valores de intensidade de fluorescência foram avaliados através do espectrofotômetro Cary Eclipse, após 1, 7 e 21 dias. RESULTADO: Não houve diferença estatisticamente significativa na Intensidade de Fluorescência entre os grupos submetidos aos diferentes protocolos de polimento. Quanto aos meios de armazenagem, a partir do sétimo dia, a variação de fluorescência foi significativamente maior em água da torneira e deionizada, quando comparada à variação observada em saliva artificial, resultado que se manteve após 21 dias. CONCLUSÃO: O protocolo de polimento superficial não promoveu alterações significativas na fluorescência da resina composta avaliada. Quanto ao meio de armazenagem, a intensidade de fluorescência foi menos afetada quando em saliva artificial.


INTRODUCTION: Resin composite is a versatile material in cosmetic dentistry due mainly to its optical properties, fluorescence among them. There are a few studies which assessed such property and a comparison of results becomes difficult due to the lack of a pattern in the specimens storage and confection methodologies. OBJECTIVE: Verify the influence of superficial polishing and means of storage in in vitro studies that assess the optical property of fluorescence in dental resin composites. MATERIAL AND METHOD: 70 circular specimens (10 mm × 2 mm) were prepared with microhybrid composite resin (Opallis, - A2E - FGM). The means of storage were: deionized water, tap water and artificial saliva. The superficial polishing protocols used 600, 1200 and 2500 sandpaper grit sizes, accomplished with polisher after specimens were obtained. The fluorescence intensity values were assessed using Cary Eclipse Fluorescence Spectrophotometer after 1, 7 and 21 days. RESULT: There was not a statistically significant difference in Fluorescence Intensity among the groups submitted to the different polishing protocols. Concerning the means of storage, from the seventh day on the fluorescence variation was significantly bigger in tap and deionized water, compared to artificial saliva, such result kept on after 21 days. CONCLUSION: the superficial polishing protocol did not promote significant changes in the assessed resin composite fluorescence. Regarding the means of storage, the fluorescence intensity was less affected when in artificial saliva.
