OBJECTIVE To evaluate tumor control with plaque radiotherapy for juxtapapillary choroidal melanoma that overhangs the optic disc. METHODS Retrospective medical record review of 141 consecutive patients with data on complications of treatment, final visual acuity, visual loss, enucleation, tumor recurrence, metastasis, and death. RESULTS The median patient age was 61 years. Presenting sympto...

This study examined the effect of follow-up intervention on periodontal health of workers on the basis of clinical assessment and a laboratory test. Toothbrushing instruction was given to 26 workers (41.4 +/- 7.8 yr of age). In the experimental group (EG), 13 workers received re-instruction and reminder messages after the initial intervention. The remaining 13 workers, who served as a control g...

Anthracosis is black pigment discoloration of bronchi which can cause bronchial destruction and deformity (anthracofibrosis). A prospective, case-control study was performed to evaluate potential underlying causes of anthracosis on 190 subjects who referred for various indications.  Age of patients ranged from 10-85 yrs. 46% of male patients were farmers and 27% were manual workers, whereas 91%...

Introduction: One of the most common problems we confront in orthodontic therapy is periodontal diseases. Initial factor which causes these diseases is colonization of anaerobic microorganisms in subgingival plaque. Technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque. However, it seems necessary to assess va...

BACKGROUND Goal of this in vivo prospective, randomized, controlled, double-blinded, cross over study was to compare the level of plaque control and gingivitis after use of a novel dental gel (test) vs. A Triclosan/copolymer dentifrice (control). METHODS After coronal polishing, 22 subjects with moderate gingivitis were randomly assigned to brush twice daily with test or control dentifrice fo...

BACKGROUND AND AIM: Bacterial plaque is the uppermost element in periodontal diseases. Chlorhexidine (CHX) is one of the utmost influential materials in chemical plaque control and ORTHOKIN is a toothpaste claimed to encompass CHX. Although there are various studies on efficacy of different types of CHX formulation in toothpaste, no literature has focused on the anti-plaque effects of toothpast...

BACKGROUND The aim of the study was to test the efficacy of a novel low-abrasive air polishing powder in subgingival plaque removal at interdental sites during periodontal maintenance therapy (PMT). METHODS Using a split mouth design, subgingival plaque was removed in 23 PMT patients using a low abrasive powder using a standard air polishing unit (test) or curets (positive control). Before an...
