Introduction & Objective: Chronic periodontitis is an inflammatory disease of the tooth supporting tissues by a specific group of microorganisms, leading to progressive destruction of the periodontal ligament. The aim of this study was to evaluate the effect of amoxicillin and metronidazole as an adjunct, after scaling and root planning in reducing pocket depth and clinical attachment loss in...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
background: transferrin is a negative acute phase protein, which decreases during inflammation and infection. the aim of the present study was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. methods: twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referre...
Numerous studies linking periodontitis and cardiovascular disease have been observed. We used a treatment intervention model to study the relationship between periodontitis and peripheral blood. We studied 37 subjects (M:F, 16:21, in age group 23-40 years) with severely periodontitis requiring scaling and root planning. Blood samples were obtained: (1) at initial presentation, (2) after 3 weeks...
هدف از این تحقیق، بررسی و مدلسازی ارتباط جنگل زدایی و متغیرهای انسانی – فیزیوگرافی ر جنگل های فلارد است. جنگل زدایی براساس کاهش درصد تاج پوشش جنگل با استفاده از تفسیر چشمی عکس های هوایی سال های 1334، 1346، 1376 و تصویر ماهواره ای سال 1387 انجام شد. رابطه ساده میزان جنگل زدایی و متغیرهای مستقل (عوامل توپوگرافی، نزدیکترین فاصله به جاده، نزدیکترین فاصله به مناطق مسکونی ، تراکم جاده، جمعیت) با استف...
This article describes and discusses a method to determine root curvature radius by using cone-beam computed tomography (CBCT). The severity of root canal curvature is essential to select instrument and instrumentation technique. The diagnosis and planning of root canal treatment have traditionally been made based on periapical radiography. However, the higher accuracy of CBCT images to identif...
