Clinical Evaluation of Giomer and Resin-based Fissure Sealants

Clinical Evaluation of Giomer and Resin-based Fissure Sealants Performed in Permanent Molar Teeth Affected by Molar-Incisor Hypomineralization

The objective of this research was to evaluate the clinical success of giomer and resin-based sealants applied in the first permanent molars (FPMs) affected by MIH.

One-hundred FPMs with MIH which were indicated for non-invasive fissure sealant were selected in 39 children (between 6-12 years). Using a split mouth design, the FPMs were randomized into two groups; Group 1: resin sealant (Conceal F); Group 2: giomer sealant (BeautiSealant) and dental isolation device was used during the procedure (Mr. Thursty). Clinical evaluation was performed by two blinded examiners using the United States Public Health Service (USPHS) criteria to assess anatomical form, marginal adaptation, surface texture, marginal discoloration, retention and secondary caries at 1, 3, 6 and 12 months. Statistical analysis was performed using SPSS 20.0 software (IBM Corp., Chicago, IL, USA) and the level of significance was set at p<0.05. The association between independent variable (groups) and dependent variable (USPHS scores) was evaluated with Fisher's exact test. The crosstabulation of the categorical data regarding the groups were analyzed with chi-square test or Fisher's exact test. The Log-rank test and Kaplan-Meier analysis were used to calculate and compare the cumulative survival rates of the sealants.

Inclusion Criteria:

• Healthy children, aged 6-12 years, who attended the pediatric dentistry clinic regular dental examination
• Cooperative children diagnosed with MIH according to European Academy of Paediatric Dentistry (EAPD) criteria
• Presenting at least two FPMs that were fully erupted and indicated for non-invasive fissure sealant.
• The FPMs with white, yellow or brown lesions, indicating mechanical and chemical alteration of the enamel and increased caries risk

Exclusion Criteria:

• Children having hypomineralized FPMs with post-eruptive breakdown, cavitated carious lesions, restorations or fixed orthodontic appliances
• Enamel defect due to a condition other than MIH
