ABSTRACT
OBJECTIVE:
This study aimed to evaluate the external and internal adaptations of cervical restorations using different restorative techniques.METHODS:
Forty extracted and intact human premolars received standardized cervical preparations to simulate non-carious cervical lesions. The teeth were randomly divided into four groups (n=10) according to the restorative technique D, direct composite restoration without a base (Palfique LX5, Tokuyama Dental Corp Inc, Tokyo, Japan); DB, direct composite restoration with a flowable composite liner (Estelite Flow Quick -High Flow, Tokuyama Dental Corp Inc); DI, direct-indirect composite restoration bonded with flowable composite; and I, indirect restoration bonded with flowable composite. Marginal adaptation of the restorations was observed in different segments of the margins using a scanning electron microscope. Analyses of internal adaptation were performed using micro-computed tomography. The Kruskal-Wallis and Mann-Whitney tests were used for statistical analysis of the data (α=5%).RESULTS:
No significant differences were found in the marginal adaptation of the groups (p>0.05), although a significantly higher percentage of continuous margin was found in the proximal segment than in the cervical segment (p<0.05). No significant differences were detected between the groups in terms of internal adaptation (p>0.05).CONCLUSION:
All the restorative techniques evaluated for the restoration of cervical lesions performed similarly in terms of marginal and internal adaptation.
