Perception of laypersons, orthodontists, and oral and maxillofacial surgeons about the transverse occlusal plane.

Introduction: Transverse occlusal plane (TOP) should be parallel to the true horizontal lines of the face (ie, the interpupillary line [IP] and commissural line [CL]). This study aimed to investigate the opinions of laypersons, orthodontists, and oral and maxillofacial surgeons about the impact of imbalanced IP and CL on facial attractiveness.

Methods: We used a symmetrical face image as the reference.

Is there any relationship between fixed orthodontic treatment and developmental indicators in children and adolescents? A prospective cohort study.

Background: Fixed orthodontic treatment may cause discomfort four to six weeks after the initiation of the treatment as it may change the type and amount of food consumed by children. This temporary change may have a long-term effect on the growth status of such children. This study aimed to detect the longitudinal relationship between fixed orthodontic treatment and developmental indicators in children and adolescents.

Prediction accuracy of Dolphin software for soft-tissue profile in Class I patients undergoing fixed orthodontic treatment.

Background: Simulation and prediction can facilitate the decision between an extraction versus nonextraction treatment plan. This study aimed to assess the accuracy of Dolphin Imaging software in predicting profile changes in class I borderline cases.

Methods: In this retrospective study, class I borderline patients (i.

Effect of Oral Bromelain on Wound Healing, Pain, and Bleeding at Donor Site Following Free Gingival Grafting: A Clinical Trial.

Objectives: Considering the optimal efficacy of bromelain for pain relief and wound healing, this study aimed to assess the effect of bromelain on wound healing, pain, and bleeding at the donor site following free gingival grafting (FGG).

Materials And Methods: This randomized, controlled double-blind clinical trial was performed on 26 patients with gingival recession. The patients were randomly divided into two groups of bromelain and placebo (n=13).

Comparing the effect of preparation of the implant sites with piezosurgery and conventional drilling on the stability of implants at 5-months follow-up.

The objective of this study was to compare the effects of preparing for implant site osteotomy with conventional drilling or piezosurgery on the stability of oral implants after a 5 month follow-up period. Thirty patients participated in this randomized clinical trial and received two implants in posterior mandible in bone of the same quality. All surgical procedures were performed by the same surgeon.

Radiographic Evaluation of Bone-Level Implants with Wound Dehiscence between the First- and Second-Stage Surgeries.

Background: One of the most common complications of implant surgery is wound dehiscence followed by exposure of the implant to the oral cavity. The aim of this study was to radiographically analyze crestal bone loss around bone-level implants with wound dehiscence between the first- and second-stage surgeries.

Methods: The records of 136 implants inserted during 2013-2014 were evaluated.

Comparison of Periodontal Ligament Stem Cells Isolated from the Periodontium of Healthy Teeth and Periodontitis-Affected Teeth.

Objectives: Stem cell (SC) therapy is a promising technique for tissue regeneration. This study aimed to compare the viability and proliferation ability of periodontal ligament stem cells (PDLSCs) isolated from the periodontium of healthy and periodontitis-affected teeth to obtain an autologous, easily accessible source of SCs for tissue regeneration in periodontitis patients.

Materials And Methods: The PDLSCs were isolated from the roots of clinically healthy premolars extracted for orthodontic purposes and periodontally involved teeth with hopeless prognosis (with and without phase I periodontal treatment).

High Insertion Torque and Peri-Implant Bone Loss: Is There a Relationship?

Because primary stability has a critical role in implant osseointegration, greater insertion torque is more desirable. However, excessive pressure on the peri-implant bone may lead to bone resorption. This study evaluates the effect of insertion torque on crestal bone level.

Effect of Periodontal Dressing on Wound Healing and Patient Satisfaction Following Periodontal Flap Surgery.

Objectives: It has been claimed that periodontal dressing reduces the risk of wound infection, bleeding and granulation tissue formation and improves tissue healing. This study sought to assess the effect of periodontal dressing on wound healing and patient satisfaction following periodontal flap surgery.

Materials And Methods: This clinical trial was conducted on 33 patients presenting to Hamadan University, School of Dentistry in 2012 whose treatment plan included two periodontal surgical procedures on both quadrants of the maxilla or mandible.

A Comparative Study of Clinical Parameters in Submerged and Non submerged Implants.

Aim: The aim of this study was to evaluate and compare the radiographic bone loss and soft tissue parameters around one stage and two stage implants.

Materials And Methods: Twenty four patients with submerged implants and twenty four patients with non submerged implants at the time of loading were assessed in this prospective cohort study. The soft tissue assessment included probing depth (PD), papilla index (PI), mucosal thickness (MT) and keratinized tissue (KG); another parameter assessed was the radiographic distance between the shoulder of the implant and alveolar crest evaluated at baseline (loading time) and 3,6 and 12 months after loading in both groups.

Evaluation of IL-8 gene polymorphisms in patients with periodontitis in Hamedan, Iran.

Background: Many environmental and genetic factors are known as factors that increase the susceptibility to periodontitis. As IL-8 is a chemokine that mediate the inflammatory process in periodontal disease, we decided to evaluate the effect of its polymorphism on chronic and aggressive periodontitis.

Materials And Methods: In this cross-sectional study DNA was isolated from the whole blood of 107 periodontitis patients and 199 healthy individuals.
