Clinical outcomes of indirect composite restorations for grossly mutilated primary molars: a clinical observation

This study was conducted to report the clinical outcomes and the parental and child satisfaction of onlays for restoring mutilated primary molars. Twenty subjects, ages 3-8 years, with the presence of at least 1 mutilated primary molar (≥3 carious surfaces and a carious surface area ≥3/4 of the occlusal surface) were recruited. This study assessed the clinical success, gingival health, and parent/child satisfaction of 28 indirect composite onlays. The onlays showed a 100% retention rate at 12 months follow-up and a marginal integrity of 96.43%. High rates of satisfactory Alpha ratings for color stability (92.86%), surface texture (92.86%), and anatomic form (100%), coupled with significant improvements in gingival health of the restored teeth (P < 0.05), were reported. Indirect composite onlays successfully restored anatomic form and function of the grossly decayed primary molars--with shorter chairside times--while satisfying the esthetic demands of the young pediatric patients.
