Immunohistochemical analysis with apoptosis and autophagy markers in periodontitis and peri-implantitis: Clinical comparative study.

Background And Objectives: Recently, the terms autophagy and apoptosis have been studied on implants, especially in cell culture and in vitro studies, but in vivo evaluations are limited. The aim of this study was to compare the differences in apoptosis and autophagy intensity at the molecular and cellular level in periodontal and peri-implant diseases.

Methods: Sixty-four biopsy samples were obtained from 52 patients, 36 female and 16 male, whose mean age was between 18 and 75, and were included in the study.

The stability of implants and microbiological effects following photobiomodulation therapy with one-stage placement: A randomized, controlled, single-blinded, and split-mouth clinical study.

Background: Studies have reported a positive effect on bone healing and the elimination of microorganisms placed on the titanium implants, while others have not confirmed the positive photobiomodulation therapy (PBMT) effects on bone regeneration and bone structure around the implants.

Purpose: The aim of the present study was to address the following questions: Does PBMT improve implant stability and affect microbiota around dental implants in the early stage of osseointegration?

Materials And Methods: This study was designed as randomized-controlled prospective, split mouth, single-blinded clinical trial. Implants were randomly divided into two groups and implants placed in the test group were treated with Gallium-aluminum-arsenide (GaAlAs) diode laser with PBMT immediately after surgery and for 15 days (n = 47).

Chemical Evaluation of Energy Dispersive X-ray Spectroscopy Analysis of Different Failing Dental Implant Surfaces: A Comparative Clinical Trial.

The aim of the present study is to compare two different implant surface chemistries of failing dental implants. Sixteen patients (mean age: 52 ± 8.27 with eight females and eight males) and 34 implants were included in the study.

The chemical surface evaluation of black and white porous titanium granules and different commercial dental implants with energy-dispersive x-ray spectroscopy analysis.

Background: The chemical surface structure of the porous titanium grafts has not been found to study in the literature on the similarity of chemical surfaces of different commercial dental implants.

Purpose: The purpose of this study is to investigate the chemical composition and surface energies of white (WPTG) and black porous titanium granules (PTG) by energy dispersive x-ray spectrometry (EDX) analysis to compare with different commercial dental implant surface.

Materials And Methods: The surface chemical compositions of six commercially available dental implants with different surface structures, PTG and WPTG were examined by EDX analysis.

The effect of different gingival phenotypes on dimensional stability of free gingival graft: A comparative 6-month clinical study.

Background: The aim of this study is to compare the effect of mesial and distal adjacent gingival phenotypes of the tooth or teeth region of free gingival graft (FGG) on the shrinkage ratio of graft at 6 months postoperatively.

Methods: Thirty-one patients with inadequate keratinized gingival width (KGW) around mandibular incisors were included in this study. The phenotype of the mesial and distal terminal teeth was evaluated by the probe transparency method and keratinized gingival thickness measurements; study groups were divided as thick and thin phenotype.

Effects of Laser Photobiomodulation and Ozone Therapy on Palatal Epithelial Wound Healing and Patient Morbidity.

Objective: The aim of this study was to compare the effects of laser photobiomodulation (PBM) and topical ozone therapy on the reepithelialization of palatal donor site wounds through clinical assessment and computer-aided image analysis and to assess the patient morbidity following free gingival graft (FGG) surgeries.

Material And Methods: Thirty-six patients requiring FGG were randomly allocated into three groups: laser group (n = 12), ozone group (n = 12), and control group (n = 12). Epithelialization was evaluated by applying 3% hydrogen peroxide (HO) to the wound area and also measured by using digital image analysis (ImageJ).

Evaluation of the effect of dose-dependent platelet-rich fibrin membrane on treatment of gingival recession: a randomized, controlled clinical trial.

Miller's class I gingival recessions (GR) have been treated using coronally advanced flap (CAF) with platelet-rich fibrin membrane (PRF membrane) or connective tissue graft (CTG). The aim of this study was to evaluate the effect of different multiple layers of PRF membranes for the treatment of GR compared with the CTG procedure. Sixty-three Miller class I GR were treated in this study.

The Comparison of Porous Titanium Granule and Xenograft in the Surgical Treatment of Peri-Implantitis: A Prospective Clinical Study.

Background: Regarding the current approach, there is no evidence to show which treatment technique is the most accurate and useful in peri-implant defects.

Purpose: The aim of this study is comparing the effect of porous titanium granule (PTG) with rotary titanium brush and the use of xenograft and collagen membrane in the treatment of intra-bony peri-implant defects.

Materials And Methods: Twenty-two patients, suffering peri-implantitis defects were included this study.
