Inter- and intra-examiner agreement of three classification systems of gingival recession.

Background: Several classifications have been proposed for gingival recession defects. Correct diagnosis of the type of gingival recession is necessary for proper treatment planning and assessment of the prognosis. Considering the existing uncertainty regarding the reliability of different classification systems available for gingival recession and their shortcomings, this study sought to assess the reproducibility and reliability of accuracy of three available classifications (Cairo, Mahajan and Miller's classification systems) for gingival recession.

Evaluation of Impacting Factors on Facial Bone Thickness in the Anterior Maxillary Region.

Background: The goal of the current study was to measure the width of the labial alveolar bone of the overlying maxillary anterior teeth, based on cone-beam computed tomography (CBCT) images, and the distance between cementoenamel junction (CEJ) and bone crest in adult patients.

Methods: A cross-sectional study was performed using a sample of 132 tomographic scans. Intact maxillary anterior with healthy periodontium and teeth was randomly selected and afterwards assessed by 2 calibrated and independent reviewers.

Detection of simulated periodontal defects using cone-beam CT and digital intraoral radiography.

Objectives:: This study sought to assess the diagnostic value of CBCT and digital intraoral radiography for the detection of periodontal defects in the sheep mandible.

Methods:: In this in vitro study, 80 periodontal defects including Grades I, II and III furcation involvements, one-, two-, three-wall and trough-like infrabony defects, fenestration and dehiscence were artificially created in the sheep mandible by burr. Intraoral digital radiographs using photostimulable phosphor plates and CBCT scans were obtained.

Relationship of Halitosis with Gastric Helicobacter Pylori Infection.

Objectives: Gastric infection with Helicobacter pylori may be one of the main causes of halitosis. This study was performed to evaluate the relationship of Helicobacter pylori infection with halitosis.

Materials And Methods: This case control study was performed on 44 dyspeptic patients with a mean age of 34.

Effects of smoking severity and moderate and severe periodontitis on serum C-reactive protein levels: an age- and gender-matched retrospective cohort study.

Background And Purpose: C-reactive protein (CRP) which might affect cardiovascular events can be affected by chronic diseases and smoking. Since the effects of smoking dosage as well as the mutual effect of smoking and periodontitis on CRP levels have not been evaluated, we aimed to assess these.

Materials And Methods: This retrospective age- and gender-matched study was performed on 120 dental patients.

Receptor activator of nuclear factor kappa B ligand and osteoprotegerin levels in gingival crevicular fluid.

Background: OSTEOCLASTOGENESIS IS COORDINATED BY THE INTERACTION OF THREE MEMBERS OF THE TUMOR NECROSIS FACTOR (TNF) SUPERFAMILY: Osteoprotegerin (OPG)/receptor activator of nuclear factor kappa B ligand (RANKL)/receptor activator of nuclear factor kappa B (RANK). The aim of this study was to investigate RANKL and OPG levels, and their relative ratio in gingival crevicular fluid (GCF) of patients with chronic and aggressive periodontitis, as well as healthy controls.

Materials And Methods: In this analytical study, GCF was obtained from healthy (n = 10), mild chronic periodontitis (n = 18), moderate chronic periodontitis (n = 18), severe chronic periodontitis (n = 20), and generalized aggressive periodontitis (n = 20) subjects.

Receptor activator of nuclear factor kappa B ligand (RANKL) levels in peri-implant crevicular fluid.

Background: Receptor activator of nuclear factor kappa B ligand (RANKL) is one of the key cytokines in the induction of osteoclastogenesis both in vitro and in vivo. Several reports indicated the presence of sRANKL in gingival crevicular fluid of patients with periodontal diseases.

Objective: To determine the presence of RANKL in peri-implant crevicular fluid samples of implants with peri-implantitis, peri-implant mucositis and healthy controls.

Relationship between obesity and periodontal status in a sample of young Iranian adults.

Aim: To examine the possible relationship between body weight and periodontal disease in a sample of the young Iranian population.

Design: An analytical (Case-Control) study.

Participants: Eighty individuals aged 18 to 34 years (40 normal and 40 overweight and obese subjects) were evaluated in this study.

Effect of general health and sociocultural variables on periodontal status of pregnant women.

Background: The influence of sociocultural variables, pre-existing conditions of general, oral and dental health and hormonal changes on periodontal status during pregnancy has been reported in some clinical studies and there has been speculation about the effects of these parameters on periodontal health during pregnancy.

Materials And Methods: This study evaluates the periodontal condition (plaque index, gingival index, probing pocket depth and clinical attachment level) of 140 pregnant women and its relationship to demographic (age, professional level and education) and clinical variables (previous pregnancy, gestation period, previous periodontal maintenance, previous live births and health status). All periodontal data were recorded by the same examiner.
