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.

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.

Dens invaginatus with necrotic pulp in a right maxillary lateral incisor with preserved vitality.

Dens invaginatus (DI) is a dental malformation occurring in several morphologic types. Consequently, treatment of teeth affected by DI can get complicated because of the complex root canal anatomy. The aim is to describe how to manage a rare report of a DI with necrotic pulp held within the vital pulp of a maxillary lateral incisor.

Class I restoration margin quality in direct resin composites: A double-blind randomized controlled clinical trial.

Purpose: To evaluate the margin quality of direct resin composite restorations comparing the enamel-dentin adhesive standard procedure with additional use of adhesive layer at the external outline.

Methods: A total of 648 teeth with Class I occlusal lesions in molars and premolars were randomly selected and distributed into two groups of 324 each in order to compare the margin quality with two restoration strategies. Lesions were sealed with the standard adhesion procedure for direct resin composite restorations (Group 1) and with an additional procedure of enamel adhesive on the outer boundary of the finished restoration (Group 2).
