Clinical Behavior of the Gingival Margin following Conservative "Coronally Dynamic" Restorations in the Presence of Non-Carious Cervical Lesions Associated with Gingival Recession: A Pilot Study.

Gingival recessions (GR) are often associated with the presence of non-carious cervical lesions (NCCL). The latter result in the disappearance of the cement-enamel junction (CEJ), with consequent difficulties both in measuring the recession itself and in performing root coverage techniques. The restoration of cervical lesions is consequently an important aspect in the treatment of GR, with the re-establishment of a "new" CEJ.

Perioral muscle activity changes after Lip Bumper treatment.

Aim: This prospective non-randomised case-control study analysed lip muscle activity after Lip Bumper (LB) treatment thought surface electromyography.

Methods: The study group was composed of 40 young patients with a mean age of 10 years and 1 month, treated with LB in the lower arch, while 40 children who did not undergo any treatment, matched for sex and age with the previous sample, constituted the control group. Measurements were performed at the beginning and after 1 year for both groups.

Effectiveness of low-level diode laser therapy on pain during cavity preparation on permanent teeth.

Purpose: To evaluate the effectiveness of low-level laser therapy (LLLT) on dental pain felt during cavity preparation of carious lesions in permanent teeth of adults.

Methods: The study was carried out on 88 teeth with dental caries requiring class I restorations in 24 subjects with a pain score ≥ 7 but < 10 measured using a 0-10 visual analogue scale (VAS) in a preliminary test of pain threshold (PTPT) for each subject receiving a class I cavity preparation on another tooth without local anesthesia. The 88 teeth included were randomly allocated to test and control groups, each with 44 teeth.
