Effect of the Combination of Restorative Material and the Etching Protocol in Enamel Microleakage in Class II Cavities after Thermocycling.

This study is aimed at evaluating the marginal microleakage of bulk-fill class II restorations after thermocycling. Thirty-two human third molars received class II cavities prepared on mesial and distal faces. The cavities were bonded according to the adhesive protocol (total or self-etching).

Distribution of anxiety and depression among different subtypes of temporomandibular disorder: A systematic review and meta-analysis.

Background: The evidence on the relationship between anxiety and depression and patients with distinct subtypes of temporomandibular disorder (TMD) is uncertain, so a thorough review study on the topic is still missing.

Objectives: This systematic review investigated the distribution and severity of anxiety and depression in patients diagnosed with different subtypes of TMD.

Methods: The study is registered in PROSPERO (CRD42020150562) and it followed the PRISMA 2020 Statement.
