Influence of Different Composites and Polishing Techniques on Periodontal Tissues near Noncarious Cervical Lesions: A Controlled, Randomized, Blinded Clinical Trial.

Abstract

OBJECTIVES:

 This study evaluated the long-term effect on gingival tissues near noncarious cervical lesions after restoration with different composites in association with two different polishing techniques.

MATERIALS AND METHODS:

 This study was conducted on 60 patients as a randomized, split-mouth, single-blind clinical trial and divided into four groups (n = 15) and restored using different composites (Tetric N-Ceram nanohibride or Z350 XT nanoparticles) and polishing materials (Astropol or Sof-Lex). The periodontal parameters analyzed were Silness-Löe plaque index; Silness-Löe gingival index; probing depth, clinical insertion level; and bleeding on probing. Periodontal analysis was performed before scaling and root planing at 30, 60, 120, and 180 days after restoration.

STATISTICAL ANALYSIS:

 The data submitted to the Friedman's test were employed for comparison between groups (p < 0.05).

RESULTS:

 Statistically significant differences between Z350/Astropol and other groups were observed for visible plaque and probing depth. Gingival index Tetric/Sof-Lex, the time factor did not influence the results. All experiment groups exhibited statistically significant differences in the clinical level of insertion when the follow-up time was considered. Percentage of bleeding on probing, in which there was a difference only with regard to group Tetric/Sof-Lex when the time factor was considered.

CONCLUSION:

 The evaluated composites and polishing techniques did not exhibit differences in performance in the periodontal parameters analyzed at the end of 6 months of evaluation.
