Risk factors associated with occlusal caries in first permanent molars in a school program: longitudinal study

Aim: Evaluate the longitudinal status of dental caries in the occlusal surface of first permanent molars (FPM) and to identify risk factors for the progression to cavitated caries lesions in a school oral health program. Methods: Children who were enrolled in the program between September 2017 and October 2019, 5 to 10 years-old, presenting the four FPM were included. Four calibrated examiners assessed dental caries according to Nyvad criteria. Descriptive analysis included frequency, mean, and standard deviation calculations. Chi-square test was used in the bivariate analysis and, logistic regression adjusted for cluster effect was used to identify significant risk factors for cavity among the following independent variables: gender, age in the baseline, deft, upper/lower molar, initial caries score, Molar Incisor Hypomineralization (MIH), fluorosis, occlusal sealing. Odds ratio (OR) and respective confidence intervals (CI) are presented. Results: From 174 children enrolled in the program between 2017/2019, 120 were reevaluated in 2022. Eleven (2.6%) FPM in 11 children (9.2%) presented cavitated caries in the follow up examination. Significant risk factors for cavity were caries experience in the primary teeth (OR = 5.59; CI: 1.4 ­ 22.3) and the presence of MIH (OR = 5.33; CI: 1.6 ­ 18.1). Most of the active lesions in the follow up were considered active in the baseline examination. Conclusions: The progression to cavity was relatively low, significantly influenced by past caries experience and MIH

Impact of masking hypomineralization opacities in anterior teeth on the esthetic perception of children and parents: A randomized controlled clinical trial.

OBJECTIVES: The aim of this study was to evaluate the impact of treating demarcated opacities in anterior teeth on the esthetic perception of children and their parents. Additionally, the masking effect was evaluated quantitively and qualitatively. METHODS: Thirty-nine patients, 8-18 years-old, presenting white-creamy opacity in permanent incisors were randomly allocated to test or control group. Test received resin infiltration and control received a placebo. The questionnaire Child's and Parent's Questionnaire about Teeth Appearance was used. The masking effect was quantitatively analyzed using the Lab System to calculate the color difference (ΔE) between the opacity and the surrounding enamel in Photoshop. Fisher's, Chi-square, Wilcoxon, Mann-Whitney tests and Spearman's correlation were applied to data analysis. RESULTS: In the test group, a significant impact on physical and psychological domains in parents' and in social domain in parents' and children's perception was observed (p<0.05). Significant difference in ΔE between test and control groups was seen from 15 min of application onwards (p<0.05). After treatment, the mean ΔE was 4.07 (SD=3.07) in the test and 7.35 (SD=3.54) in the control group (p<0.01). One month later, the mean ΔE was 4.22 (SD=2.96) in the test and 6.06 (SD=2.52) in the control group (p<0.01). Total masking was seen only in the test group (p<0.01). CONCLUSION: Aesthetic treatment of hypomineralization opacities in anterior teeth with resin infiltration impacted positively on parents and children. Resin infiltration reduced the color difference between opacities and sound enamel significantly after an application time of at least fifteen minutes. CLINICAL SIGNIFICANCE: Opacities in anterior teeth impact the self-image of children and parents negatively. This study demonstrated that 15 min resin infiltration can mask opacities in permanent incisors and recover social wellbeing. This minimally invasive approach can be offered to MIH children who report dissatisfaction with their incisors.

Esthetic rehabilitation in primary and permanent successors incisors in a child with conoidal and absence teeth: a case report

Objective: To show the aesthetic treatment performed in deciduous incisors and in permanent successors in a child with congenital dental abnormalities (conoid and missing teeth), which associated with bone disproportion of the middle third of the face led to a suspicious diagnosis of ectodermal dysplasia. Case report: This report was written following the CARE Statement. A 6-year-old girl attended the Pediatric Dental Clinic complaining about bullying due to appearance her teeth. The reanatomization of the conoid-shaped deciduous incisors was done with direct composite resin using preformed acetate crowns. After 15 months, the deciduous incisors had exfoliated and the permanent incisors erupted also with a conoid shape. For aesthetic rehabilitation, direct composite restorations were performed using the incremental technique guided by a silicone matrix made based on the diagnostic wax-up. Conclusion: In the follow-up, the patient and guardians reported satisfaction with appearance of her smile and an increased self-esteem. The case remains under follow-up and future planning will include orthodontics and prosthodontics.

Objetivo: Mostrar o tratamento estético realizado em incisivos decíduos e em seus sucessores permanentes em uma criança com anomalias dentárias congênitas (dentes conoides e ausentes), que associado a desproporção óssea do terço médio da face levaram a um diagnóstico suspeito de displasia ectodérmica. Relato de caso: Este relato foi redigido seguindo o CARE Statement. Menina de 6 anos de idade compareceu à Clínica de Odontopediatria com queixa de bullying devido à aparência de seus dentes. A reanatomização dos incisivos decíduos conoides foi feita com coroas de acetato pré-formadas e resina composta direta. Após 15 meses, os incisivos decíduos esfoliaram e os incisivos permanentes irromperam também com formato conoide. Para a reabilitação estética, foram realizadas restaurações diretas com resina composta pela técnica incremental guiada por matriz de silicone confeccionada a partir do enceramento diagnóstico. Conclusão: No seguimento, paciente e responsáveis relataram satisfação com a aparência do sorriso e aumento da autoestima. O caso continua em acompanhamento e o planejamento futuro incluirá ortodontia e prótese dentária.
