Control de la caries no restaurativa en incisivos centrales primarios, a los 36 meses de seguimiento / Controle cavitário não restaurador em incisivos centrais decíduos com 36 meses de acompanhamento / Non-restorative cavity control in deciduous central incisors at 36-month follow-up

La mínima intervención ha ido ganando cada vez más notoriedad en la Odontología, reflejando una creciente demanda por parte de los profesionales que buscan técnicas que promuevan tratamientos eficientes y que preserven la estructura dentaria. Objetivo: El presente estudio tuvo como objetivo promover el control de caries no restaurador (CCNR) en un paciente infantil, mediante una regularización de la cavidad de la lesión cariosa para permitir una mejor limpieza del área, junto con un protocolo complementario de fluoración. Presentación de caso: Paciente masculino de 4 años de edad con higiene bucal satisfactoria, sin embargo con acumulación de biopelícula entre los incisivos centrales superiores y sin síntomas ni quejas estéticas. Se alisaron las caras mesiales de los incisivos centrales con tiras abrasivas para eliminar zonas socavadas y facilitar el acceso para mejorar la higiene bucal, y se aplicó el barniz de flúor en 4 sesiones, con un intervalo de una semana entre cada aplicación. La madre de la paciente fue instruida sobre cuidados de higiene y alimentación. Durante 36 meses se realizó seguimiento clínico y radiográfico del paciente con retornos cada 12 meses. También se reevaluaron el índice de placa visible y los resultados de la guía de higiene y dieta. Conclusión; En este caso clínico, la fluorterapia asociada a la regularización superficial demostró ser una alternativa de tratamiento exitosa a largo plazo, permitiendo la preservación del tejido dentario y previniendo la progresión de las lesiones cariosas. El concepto ultraconservador puede ser una alternativa válida por su eficacia, sencillez, bajo coste y buena aceptación por parte de los niños y sus padres

The minimal intervention has been gaining more notoriety in Dentistry, reflecting growing demand from professionals looking for techniques that promote efficient treatments and preserve the dental structure. Objective: The present study aimed to promote non-restorative cavity control (CCNR) in a child patient through regularization of the cavity of the carious lesion to allow better cleaning of the area, together with a complimentary fluoride protocol. Case presentation: Male patient, 4 years old, presenting adequate oral hygiene. However, biofilm accumulation occurs between the upper central incisors without symptoms or aesthetic complaints. Therefore, the mesial surfaces of the central incisors were smoothed with abrasive strips to remove undercut areas and facilitate access to improve oral hygiene. The fluoride varnish was applied in 4 sessions, with an interval of one week between each application. The patient's mother was instructed on hygiene and diet care. During 36 months, there was a clinical and radiographic follow-up of the patient with returns every 12 months. The visible plaque index and the hygiene and diet guidance results were also re-evaluated. Conclusion: In this clinical case, surface regularization associated fluortherapy proved to be a successful long-term treatment alternative, allowing the preservation of dental tissue and preventing the progression of caries lesions. The ultra-conservative concept can be a valid alternative due to its effectiveness, simplicity, low cost, and good acceptance by children and their parents.

Diagnosis training and calibration for epidemiological studies on primary and permanent teeth with hypomineralization.

PURPOSE: The objective of this study was to assess the impact on diagnostic accuracy and Kappa values improvement during the three-phase training and calibration process for MIH/HSPM. METHODS: Thirty dentists were calibrated as examiners for diagnosis of Molar Incisor Hypomineralization (MIH) using Ghanim's index. The whole process was divided into three phases. Phase 1: three meetings with the dentists for the first diagnosis training and calibration (sessions 1a and 1b); phase 2: for a period of 1 month, the dentists started practicing MIH/HSPM diagnosis in the Basic Health Units and an online follow-up group was created to discuss cases and resolve doubts; phase 3: two meetings with the dentists for the second calibration (sessions 2a and 2b). A webpage with educational material was prepared as support during the whole process to improve the dentists' skills in diagnosing MIH/HSPM. The examiners' responses were compared to a gold standard and the Kappa value was obtained. RESULTS: The average clinical criteria kappa value of the examiners was 0.76 ± 0.19 for the first calibration and 0.93 ± 0.07 (p < 0.05) for the second calibration. For the eruption criteria, the average kappa value was 0.89 ± 0.14 for the first calibration and 0.98 ± 0.08 for the second calibration. Extension criteria had an average kappa value of 0.59 ± 0.15 during the first calibration and 0.75 ± 0.14 during the second calibration. CONCLUSION: This study demonstrated that the methodology used was an effective tool for improving the diagnostic accuracy of MIH/HSPM.

Maternal-Child Health Indicators Associated with Developmental Defects of Enamel in Primary Dentition.

Purpose: To assess the prevalence and severity of developmental defects of enamel (DDE) in primary teeth and maternal-associated factors. Methods: This cross-sectional study included 336 two- to four-year-old children who attended the National Day of Children's Vaccination in São Paulo State, Brazil. The modified DDE index was used for diagnosis. Mothers completed sociodemographic and health questionnaires. Descriptive and Poisson regression analyses were performed. Results: The prevalence of DDE was 50.6 percent. The most frequent defects were demarcated opacities (45.0 percent), diffuse (36.0 percent) opacities, and hypoplasia (5.8 percent). White opacities were predominant (64.8 percent) in the teeth with defects, followed by cream (20.4 percent), yellow (5.2 percent), and brown (1.9 percent). Most defects involved less than one-third of the tooth surface (80.2 percent). The prevalence of DDE was associated with maternal-child factors such as alcohol consumption during pregnancy (prevalence ratio [PR] equals 1.27; 95 percent confidence interval [95% CI] equals 1.03 to 1.55), child hospitalization for infectious disease in the first year of life (PR equals 1.32; 95% CI equals 1.05 to 1.67), and breastfeeding for the first 12 months of life (PR equals 0.53; 95% CI equals 0.45 to 0.62). Conclusions: Developmental defects of enamel showed high prevalence and mild severity in the primary dentition. Alcohol consumption during pregnancy and child hospitalization for infectious diseases in the first year of life were associated with an increased prevalence of DDE. Moreover, children who breastfed for 12 months had a lower prevalence of DDE in primary teeth.

Barriers and facilitators to dental care during pregnancy: a systematic review and meta-synthesis of qualitative studies.

Some barriers to dental treatment during pregnancy are poorly understood, especially those related to psychosocial factors, which are better explored in qualitative studies. The aim of this systematic review was to explore the barriers and facilitators to dental care during pregnancy through a thematic synthesis of qualitative studies. Qualitative or mixed-methods studies published in English, Portuguese, Spanish and French, from 2000 to 2016, were included. The search strategies were conducted in PubMed, Scopus, Web of Science, LILACS, BBO and CINAHL. To evaluate the quality of the studies, we used the Critical Appraisal Skills Programme tool. Thematic synthesis was performed in order to interpret and summarize the results. From 2,581 screened studies, ten were included in the synthesis. We found 14 analytical themes related to barriers and facilitators to dental care during pregnancy that interacted in complex ways: physiological conditions, low importance of oral health, negative stigma regarding dentistry, fear of/anxiety toward dental treatment, mobility and safety, financial barriers, employment, time constraints, social support, lack of information, health professionals' barriers, family and friends' advice, beliefs and myths about the safety of dental treatment. Myths and beliefs about oral health and dental treatment during pregnancy appear to be the most frequent barriers, both to pregnant women and to dentists or other health professionals. The findings of this review may support new studies, especially to test intervention protocols and to guide effective public policies for the promotion of oral health during pregnancy.

Determinants of Dental Care Attendance during Pregnancy: A Systematic Review.

Despite the fact that dental care attendance during pregnancy has been recommended by guidelines and institutions, the demand for dental services is still low among pregnant women. The aim of this study was to identify and analyze the determinants of dental care attendance during pregnancy. We performed a systematic literature search in the electronic databases PubMed, Scopus, Web of Science, Latin American and Caribbean Health Sciences Literature, Brazilian Library in Dentistry, Cumulative Index to Nursing and Allied Health Literature, and Medline using relevant keywords. Studies were filtered by publication year (2000-2016) and language (English, Portuguese, Spanish, and French). The included studies were assessed for quality. Their characteristics and statistically significant factors were reported. Fourteen papers were included in the review. The prevalence of dental service usage during pregnancy ranged from 16 to 83%. Demographic factors included women's age, marital status, parity, and nationality. The socioeconomic factors were income, educational level, and type of health insurance. Many psychological and behavioral factors played a role, including oral health practices, oral health and pregnancy beliefs, and health care maintenance. Referred symptoms of gingivitis, dental pain, or dental problems were perceived need. Demographic, socioeconomic, psychological, behavioral factors and perceived need were associated with the utilization of dental services during pregnancy. More well-designed studies with reliable outcomes are required to confirm the framework described in this review.

Algumas barreiras aos cuidados de saúde bucal durante a gravidez são mal compreendidas, principalmente aquelas relacionadas a fatores psicossociais, que são exploradas melhor com estudos qualitativos. Esta revisão sistemática teve como objetivo explorar as barreiras e facilitadores dos cuidados odontológicos durante a gravidez, através de uma síntese temática de estudos qualitativos. Foram incluídos estudos qualitativos ou de métodos mistos, publicados em inglês, português, espanhol ou francês entre 2000 e 2016. As buscas foram realizadas nas bases PubMed, Scopus, Web of Science, LILACS, BBO e CINAHL. Para avaliar a qualidade dos estudos, usamos a ferramenta Critical Appraisal Skills Programme. A síntese temática teve como objetivo interpretar e resumir os resultados. Entre os 2.581 estudos identificados, dez foram incluídos na síntese. Encontramos 14 temas analíticos relacionados a barreiras e facilitadores dos cuidados odontológicos na gravidez, e que interagiram de maneira complexa: condições fisiológicas, baixa importância atribuída à saúde oral, estigma negativo em relação à odontologia, medo ou ansiedade frente ao tratamento dentário, mobilidade e segurança, barreiras financeiras, emprego, limitações de tempo, apoio social, falta de informação, barreiras produzidas pelo profissional de saúde e conselhos de amigos e familiares, além de crenças e mitos sobre a segurança do tratamento dentário. Os mitos e crenças sobre a saúde oral e o tratamento dentário durante a gravidez parecem ser as barreiras mais importantes, tanto para as gestantes quanto para os odontólogos e outros profissionais de saúde. Os achados da revisão podem apoiar novos estudos, principalmente para testar protocolos de intervenção e orientar políticas públicas efetivas para a promoção da saúde oral durante a gravidez.
