Intelligence quotient level and treatment of obsessive-compulsive disorders: Meta-analyses.

Background: Obsessive-compulsive disorder (OCD) is a highly heterogeneous mental disorder that could affect mental capacity and requires different treatment methods. The purpose of this meta-analysis study was to evaluate the OCD subjects' intelligence quotient (IQ) and the effect of different treatments on OCD.

Methods: Through a systematic literature search up to December-2019, 108-studies were identified, with 8049-subjects with 6719-OCD subjects.

[Comparison of expression of transforming growth factor-β1 in rat dental pulp during direct pulp capping with 2 capping agents].

Purpose: To examine and compare the expression of transforming growth factor-β1(TGF-β1) in rat dental pulp after direct pulp capping with calcium hydroxide (CH) and mineral trioxide aggregate (MTA).

Methods: The model of direct dental pulp capping after first molars was established in 28 female Wistar rats with CH and MTA. The rats were sacrificed 1, 3, 5, 7, 14,21 and 28 days after direct pulp capping.
