Evaluation of the efficacy of various remineralization agents and grape seed extract on microhardness and lesion depth of primary tooth enamel: An in vitro study.

Background: This study evaluated the efficacy of grape seed extract (GSE) on the remineralization of primary tooth enamel alone or in combination with remineralizing agents.

Methods: The initial microhardness value of 90 primary tooth enamel samples was calculated; then, the samples were demineralized. The post-demineralization hardness of the samples was measured and the samples were randomly divided into 6 groups as follows: G1: negative control, G2: GSE, G3: NaF, G4:Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), G5: GSE+NaF, and G6: GSE+CPP-ACP (n=15).

The Effects of Blepharoptosis Surgery on Meibomian Gland, Tear Film, and Corneal Topography.

Objectives: The objective of this study was to evaluate the Meibomian gland (MG), tear film, and corneal changes in the post-operative period following ptosis surgery using corneal topography.

Methods: This non-comparative, case series study analyzed 30 eyes of 23 patients undergoing blepharoptosis surgery with an external approach. Ocular surface and tear film evaluation was performed at baseline and post-operative 3rd month.

A living material platform for the biomineralization of biosilica.

Nature has a vast array of biomineralization mechanisms. The commonly shared mechanism by many living organisms to form hardened tissues is the nucleation of mineral structures via proteins. Living materials, thanks to synthetic biology, are providing many opportunities to program cells for many functionalities.

Hormonal changes in consecutive clomiphene citrate stimulation cycles and their effect on pregnancy rates.

Objective: To determine the relationship between the cumulative effect of sequential clomiphene citrate (CC) treatments in unexplained infertile women with intercycle and intracycle serum hormone changes.

Materials And Methods: Patients who received CC 50 mg in the first cycle (group I, n=34) as ovulation induction and those who received CC 50 mg in the second consecutive cycle (group II, n=18) were compared. Basal (cycle days 2-5) and trigger day (the day that recombinant human chorionic gonadotropin is given) levels of gonadotropin and steroid hormones were measured.

Evaluation of Peripapillary and Macular Vascular Flow Changes with OCT-A in Patients with Superficial Optic Disk Drusen.

Objectives: The purpose of this study was to compare the peripapillary and macular vascular flow changes between healthy adults and adult patients with superficial optic disk drusen (ODD), as evaluated by optical coherence tomography angiography (OCT-A).

Methods: In this retrospective study, 44 eyes of 22 patients with superficial ODD followed-up in our neuro-ophthalmology unit and 54 eyes of 27 healthy individuals admitted to our clinic for routine ophthalmological examination were included in the study. The superior, inferior, nasal, and temporal radial peripapillary capillary plexus (RPC) vessel density (VD) values; superior, inferior, nasal, and temporal parafoveal and foveal region superficial capillary plexus (SCP) and deep capillary plexus (DCP) VD values; and choriocapillaris flow (CCF) area and foveal avascular zone area were evaluated by OCT-A.
