background and aim: probing is the only reliable method for diagnosing periodontal diseases; however, it is a painful examination. the purpose of this study was evaluation of the effect of emla anesthetic gel on the level of pain upon probing in patients with chronic periodontitis referring to the periodontology department of the dental branch of islamic azad university of tehran during 2013-20...

in this study 100 cases of advanced periodontitis were compared with a control group of 100 persons. the parameters were the depth of the periodontal pockets, radiographic images, presence of inflammatory cells and different types of anaerobic bacteria in the pockets. the depth of pocket was measured by a sterile probe and the presence of inflammatory cells was determined through sterile curett...

conclusions the results of the present study suggest that the presence of fusobacterium species in periodontal pockets is an important risk factor for halitosis. results in total, 26% (n = 13) and 8% (n = 4) samples were positive for fusobacterium species in the halitosis and control groups, respectively, with f. nucleatum present in the greatest proportion in both groups. halitophobia was sign...

PURPOSE The purpose of this study was to examine whether periodontal pocket could be satisfactorily visualized by optical coherence tomography (OCT) and to suggest quantitative methods for measuring periodontal pocket depth. METHODS We acquired OCT images of periodontal pockets in a porcine model and determined the actual axial resolution for measuring the exact periodontal pocket depth using...

A seven years old boy visited our clinic with a periodontal problem related to an erupting lower molar. The tooth showed a 15 mm deep periodontal pocket on the buccal aspect. A microbiologic DNA-test excluded a periodontal origin. The treatment consisted in a local antimicrobial therapy with cleaning and filling up of the pocket with Atridox. Two years after therapy the pocket completely disapp...

introduction: the aim of the present study was to investigate the effects of srp assisted by the two clinical treatment methods of diode laser or chlorhexidine gel applications in comparison with srp alone. methods: eight patients with moderate to severe chronic periodontitis, each with at least three pockets 4–7 mm deep, were selected for this study. over 66 pockets were selected and randomly ...

introduction: deep periodontal pockets pose a great challenge for nonsurgical periodontal treatment. scaling and root planing (srp) alone may not suffice in cases where surgical therapy cannot be undertaken. various recent studies have suggested the use of antimicrobial photodynamic therapy (apdt) for the management of periodontal infections. the aim of this study was to evaluate the effects of...

Bivariate clustered (correlated) data often encountered in epidemiological and clinical research are routinely analyzed under a linear mixed model (LMM) framework with underlying normality assumptions of the random effects and within-subject errors. However, such normality assumptions might be questionable if the data set particularly exhibits skewness and heavy tails. Using a Bayesian paradigm...
