Chutima Trairatvorakul / Supatcharin Piwat

This study compares the clinical characteristic evaluations of slot against dovetail class III composite restorations.Focusing on the primary anterior teeth of children aged 2 years 6 months to 5 years 3 months with the mean age of 4 years, thirty-six matched pairs of class III of slot and dovetail preparations were made by one investigator. These preparations were evaluated for marginal adaptation, anatomic form, secondary caries and marginal discoloration after 6, 12, and 24 months by another investigator with the intra-examiner reliability of 0.95 – 1 (Kappa Statistic). The results revealed no statistical significance in the difference of clinical characteristics between the two designs (p > 0.05).
