AIM The haptoglobin-hemoglobin (Hp-Hb) complex plays a significant role in regulating immune responses and acts as a bacteriostatic agent. Haptoglobin polymorphisms result in different Hb binding affinities. This study sought to assess whether Hp 2-2 could be a genetic determinant for increasing the risk of peri-implantitis and chronic periodontitis. (More)
INTRODUCTION Low level laser therapy (LLLT) also known as photobiomodulation, is a treatment that uses low-level lasers or light-emitting diodes (LEDs) to change cellular function and is a clinically well accepted tool in regenerative medicine and dentistry. Considering the variety of laser, exposure, cells and study types, the exact effects of low level(More)
Gene polymorphism of cytokines influencing their function has been known as a contributing factor in the pathogenesis of inflammatory diseases of the tooth and implant supporting tissues. The aim of this study was to investigate the association of IL-17R gene polymorphism (rs879576) with chronic periodontitis and periimplantitis in an Iranian population. 73(More)
OBJECTIVE RANK/OPG/RANKL pathway plays a significant role in osteoclastogenesis, osteoclast activation, and regulation of bone resorption. The aim of this study was to investigate the association of RANKL gene polymorphisms (rs9533156 and rs2277438) with chronic periodontitis and peri-implantitis in an Iranian population. DESIGN 77 patients with chronic(More)
Periodontal disease (PD) and peri-implantitis (PI) are characterized by an immune response leading to destructive inflammation. The prominent impact of genetic factors on periodontitis has been previously evaluated and IL-17 has found to play a critical role in this process. This cytokine has a controversial behavior. This study aimed at finding out whether(More)
PURPOSE Receptor activator for nuclear factor kappa B ligand (RANKL)/RANK/OPG pathway plays a redundant role in osteoclastogenesis, osteoclast activation and regulation of bone resorption. Recently, single nucleotide polymorphisms (SNP) have been reported as a co-factor in pathogenesis of inflammatory diseases. The aim of this study was to investigate the(More)
Chronic periodontitis (CP) and peri-implantitis (PI) are multifactorial diseases of tooth and implant supporting apparatus. Bacterial invasion and consequent host immune response seem to play a role in relevant pathogenesis. The structural differences between tooth and implant pose preferential biofilm colonization. This study was aimed to compare the(More)
UNLABELLED This study sought to determine TANK (rs1921310, rs3820998) gene polymorphism in patients suffering from chronic periodontitis and peri-implantitis among an Iranian population. MATERIALS AND METHODS In this cross-sectional study, 77 chronic periodontitis and 40 peri-implantitis patients, along with 89 periodontally healthy subjects, were(More)
BACKGROUND Different techniques have been proposed for the treatment of gingival recession. The majority of current procedures use autogenous soft-tissue grafts, which are associated with morbidity at the donor sites. Acellular dermal matrix (ADM) Alloderm is an alternative donor material presented to reduce related morbidity and provide more volume of the(More)
PURPOSE This study aimed to assess the combined effect of dismantling before sterilization and aging on the accuracy (±10% of the target torque) of spring-style mechanical torque devices (S-S MTDs). METHODS Twenty new S-SMTDs from two different manufacturers (Nobel Biocare and Straumann: 10 of each type) were selected and divided into two groups, namely,(More)
