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

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 ( = 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.

Microbiological evaluation of ultrasonic nebulization for disinfecting dental impressions.

Disinfecting dental impressions is necessary to decrease the risk of cross-contamination in dental offices. Ultrasonic nebulization has been mentioned as a microbicidal technique that can be used to disinfect contaminated dental impressions. This study compared the microbicidal effect of 2% glutaraldehyde and 0.
