Official Title: Survival of Sealants in Molars Affected by Molar-Incisor Hypomineralization
Brief Summary:
Aim: To evaluate the clinical survival of fluoride sealants applied in first permanent molars affected by Molar-Incisor Hypomineralization (MIH).
Material and Methods: For this case control study, it was selected 41 first permanent molars of the 21 children aged 6-8 years. MIH was classified by one calibrated examiner (kappa 0.80) according severity of the MIH lesion (EAPD, 2003). Inclusion criteria were FPM with MIH or sound (without MIH), fully erupted, and with sealant treatment indication.
The FPMs were assigned into two groups: G1 - Control group and G2 - MIH group. Both group teeth were treated with sealant application (Fluroshield, NY, USA). Clinical follow-up was performed at baseline, 1, 6, 12 and 18 months for anatomic form, marginal adaptation, retention and presence of caries, according to the United States Public Health Service USPHS-Modified by a blinded examiner (kappa 0.80). The Acturial Method was used to evaluate the survival of sealants. Statistical analysis compared the ratings of each criterion between materials using the Fisher's exact test at a level of significance of 5% (p<0.05).
Detailed Summary:
This study was conducted according to the Helsink Declaration. The approval was obtained from the Ethics and Research Committee at Araraquara Dental School, São Paulo, Brazil (protocol #11/09). All parents/guardians of the children signed the informed consent.
Study design:
This case control study included four clinical exams performed in 6 to 8 years-old children that received preventive treated with sealants, divided into 2 groups: G1 - teeth not affect by MIH and G2 - teeth affect by MIH.
Subjects:
The 21 children included in the study had been previously diagnosed with MIH, according to the EAPD criteria. A total of 41 first permanent molars teeth (FPM) were included, being 16 without MIH and 25 with MIH.
Calibration of the examiner for the evaluations:
The examiner was calibrated according to MIH based on criteria proposed by the European Academy of Pediatric Dentistry and for USPHS-Modified. The examiner assessed 32 clinical photographs of patients from the Clinic of Pediatric Dentistry of the Araraquara Dental School in São Paulo, Brazil, followed by a discussion with the MIH research team of all the indices and codes. After an agreement, 30 patients with enamel alterations (17 of them with MIH) were evaluated. After 2 weeks, the patients were reevaluated and the Kappa coefficient was used to verify the agreement between the evaluations. The intra-examiner values for MIH and USPHS-modified were 0.80.
Treatment:
The 41 FMP were clinically examined and classified according the presence of MIH according the Europea
