Aim: To evaluate the spatial distribution of MIH opacities in first permanent molars (FPM). Materials and methods: an analysis of intraoral photographs of FPM with demarcated MIH opacities was conducted. The presence of opacity was computed in a digital matrix, discriminating the anatomical regions of the FPM surfaces. The frequencies of distribution of the opacities were descriptively analyzed through 227 FPM digital images of 89 children built in GIMP and Python and by Spearman correlation (= 0,05). Results: the occlusal surface was the most affected one (94% to 100%). In the upper FPM, the palatine surface was the second most affected one (84%-91%). In the lower FPM, the vestibular surface was the second most affected one (85%-80%). A similar pattern of opacity distribution was observed in the contralateral teeth. On smooth surfaces, opacities were more frequent in the regions closer to the occlusal surface than to the cervical one. Conclusion: MIH opacities were mostly present on occlusal, vestibular, and lingual/palatine surfaces, respectively. There is a possibility that the occurrences are in accordance with the chronology of dental formation.

How much does household food insecurity explain income inequalities in untreated dental caries?

BACKGROUND: The pathway by which socioeconomic disadvantages are manifested in the occurrence of dental caries remains unclear. AIM: To explore how much the association between untreated dental caries and income inequalities is related to household food insecurity (HFI). DESIGN: A population-based study was conducted with a sample of 466 12-year-old students. Dental caries was evaluated by an examiner who had undergone calibration exercises. HFI was assessed using the Food Insecurity Scale validated for Brazilian Portuguese. Poisson regression models were created to determine associations between dental caries and both household income and HFI. The proportion of the income effect on dental caries explained by HFI was determined by the variation in percentages between the crude prevalence ratio (PRc ) for dental caries and this measure adjusted by HFI (PRa ). RESULTS: The prevalence of dental caries was higher among children from families with a per capita household income lower than US$ 71 (PR: 1.69; 95%CI: 1.15-2.49) or from US$ 71 to US$ 142 (PR: 1.50; 95%CI: 1.04-2.17). Moreover, 14% of the association between a low income and dental caries was explained by HFI. CONCLUSIONS: Differences in the prevalence of dental caries in schoolchildren related to socioeconomic inequalities could partially be attributed to HFI in low-income families.

Silver Diamine Fluoride Has Efficacy in Controlling Caries Progression in Primary Teeth: A Systematic Review and Meta-Analysis.

A systematic review was performed to evaluate the efficacy of silver diamine fluoride (SDF) in controlling caries progression in children when compared with active treatments or placebos. A search for randomized clinical trials that evaluate the effectiveness of SDF for caries control in children compared to active treatments or placebos with follow-ups longer than 6 months was performed in PubMed, Scopus, Web of Science, LILACS, BBO, Cochrane Library, and grey literature. The risk of bias tool from the Cochrane Collaboration was used for quality assessment of the studies. The quality of the evidence was evaluated using the GRADE approach. Meta-analysis was performed on studies considered at low risk of bias. A total of 5,980 articles were identified. Eleven remained in the qualitative synthesis. Five studies were at "low," 2 at "unclear," and 4 studies at "high" risk of bias in the key domains. The studies from which the information could be extracted were included for meta-analysis. The arrestment of caries at 12 months promoted by SDF was 66% higher (95% CI 41-91%; p < 0.00001) than by other active material, but it was 154% higher (95% CI 67-85%; p < 0.00001) than by placebos. Overall, the caries arrestment was 89% higher (95% CI 49-138%; p < 0.00001) than using active materials/placebo. No heterogeneity was detected. The evidence was graded as high quality. The use of SDF is 89% more effective in controlling/arresting caries than other treatments or placebos. The quality of the evidence was graded as high.

Abordaje conservador y mínimamente invasivo de la Hipomineralización Molar-Incisivo (HMI) -Relato de casos clínicos / Minimally invasive treatment for esthetic management of Molar-Incisor Hypomineralization (MIH) -A case report

La Hipomineralización Molar-Incisivo (HMI) es un defecto de esmalte de origen sistèmico que afecta uno o varios molares permanentes, asociado en algunos casos a los incisivos permanentes. Defectos de esmalte, como la HMI pueden influenciar negativamente la calidad de vida, percepción estètica y autoestima de niños y adolescentes. Las opciones de tratamiento para este tipo de alteración, incluye desde medidas preventivas y procedimientos restauradores hasta la extracción dental. Factores como la edad y expectativas del paciente, severidad de la alteración y materiales deben ser considerados en el plan de tratamiento del paciente con HMI. La utilización de resinas compuestas para la restauración de molares e incisivos ha mostrado buenos resultados relacionados a la durabilidad y estètica. Este artículo presenta dos casos clínicos sobre el abordaje de la HMI en dientes anteriores, realizando preparos cavitários conservadores por medio de puntas ultrasónicas adaptadas a un sistema de ultrasonido y restauración con resina compuesta, obteniendo resultados estéticos favorables con un año de acompañamiento.

Molar-Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that affects one to four permanent first molars, with or without involvement of permanent incisors. Enamel defects may produce many symptoms that have physical, social and psychological effects and influence day-to-day living or quality of life. The available treatment modalities for teeth with MIH are extensive, ranging from prevention, restoration, to extraction. Factors such as age, patient expectations, severity of the lesion and materials should be considered in the treatment of the patient with MIH. Restoration with composite resin is an alternative choice for posterior and anterior MIH defective teeth and its use has been show acceptable results. This article describes two clinical cases involving pediatric patients with MIH whose procedure of cavity preparation was based on the use of CVD ultrasound diamond tips and restored using composite resin obtaining favorable esthetics results after a 1 year follow-up.
