ABSTRACT

Xerostomia is a common complication of radiotherapy for head and neck cancer which can increase the risk of oral and dental disease and negatively affect patients' quality of life. The aim of this study is to evaluate the efficacy of Iranian Made Saliva Substitute vs. VA-OraLube in improvement of Oral-Health-Related Quality of Life. This study was a randomized double-blinded, crossover clinical trial. 27 patients [49.1 +/- 14.7 years] with post-radiotherapy xerostomia were randomly allocated to receive either Iranian Made Saliva Substitute or VA-OraLube, or vice versa, each product for 1 week, with a 10 day wash-out period in between. The European Organization for Research and Treatment of Cancer Questionnaire Head and Neck Cancer Module [EORTC-QLQ-H and N 35] was completed by patients at days 1,8,18 and 25. To compare the groups the repeated measurement analysis of variance test was used then comparison of paired was performed by t-paired test. Oral-Health-Related Quality of Life score has been changed almost the same degree by both VA-OraLube and Iranian made saliva substitute and both treatments were effective. But none of them affected pain relief. A trend was seen for VA-OraLube to improve senses. With regard to significant improvement in Standard score in different group of questionnaire after using saliva substitute, both saliva substitutes were effective in alleviating the symptoms of xerostomia and helping patients to have better life

ABSTRACT

Lymphoma is a group of cancers that originates in the lymphatic system, but extranodal regions may be involved. As the head and neck areas are in the field of dentistry so a dentist has an important role in early diagnosis. The aim of this study was to evaluate the prevalence of lymphoma and involvement of cervico-facial tissues in patients with Hodgkin disease and non-Hodgkin's lymphoma. This descriptive study was conducted on medical records of 55 patients presented lymphoma, 9 cases with Hodgkin's disease [HD] and 46 cases with Non Hodgkin's Lymphoma [NHL], mainly for involvement of cervico-facial tissues and lymphadenopathy in cancer department of Iman Khomaini Hospital [2004]. Data was analysed by using SPSS 11 statistical software. Data revealed that the mean age in patients with HD was 47 +/- 7.18 and in NHL, 55 +/- 18 years old. The most site of lymphadenopathy was observed in the neck [88.8 in HD and 56.5 in NHL]. In 17.4% of patients with NHL, lymphadenopathy was found in submandibular, parotid and submental regions. According to the staging, 61% of patients were in stages I and II. The most common diagnostic method was incisional biobsy. Attention to cervico-facial and oral manifestation of lymphoma is effective in early diagnosis

ABSTRACT

Recurrent aphthous stomatitis [RAS] is one of the most common diseases affecting the oral mucosa. Many topical and systemic medications used to treat RAS have adverse local and systemic effects. Chamomill [kamillosan] has been shown to be an effective drug, without any noticeable side effects. The aim of present study was to assess the efficacy of a chamomill mouthrinse on RAS in comparison with a placebo mouthrinse. The study was designed as a double blind randomized placebo controlled clinical trial with participation of 50 patients diagnosed with RAS. They were randomly divided into two groups: 26 patients forming the test group, received chamomill mouthrinse and 24 patients constituting the control group received a placebo rinse. All subjects were instructed to use the solutions three times a day until complete resolution of the lesions. Treatment outcome was assessed on days 3 and 5 and at the exact healing time. The ability of the solution to control the pain and burning sensation and the diameter of the ulcers was evaluated. Statistical analysis was performed using the X2 and unpaired t test for comparison between the two groups. The chamomill group showed a significant reduction in the time required for controlling the pain and burning sensation [P<0.01]. Ulcer diameter and healing time were also decreased [P<0.01]. Chamomill mouthrinse was effective in the treatment of RAS without producing adverse effect

ABSTRACT

Digital measurement of RVG may improve diagnostic interpretation of radiographs in terms of accuracy, although it has been shown that validity of linear measurements of interproximal bone loss could not be improved by basic digital manipulations. The aim of this study was to evaluate the accuracy of RadioVisioGraphy [RVG] in the linear measurement of interproximal bone loss in intrabony defects. Thirty two radiographs of 56 periodontally diseased teeth exhibiting interproximal intrabony defects were obtained by a standardized RVG technique and Intrabony defect depths were determined by linear measurement analysis of RVG. The following four distances were assessed intrasurgically: the cemento enamel junction [CEJ] to the alveolar crest, the CEJ to the deepest extention of the bony defect [BD], the occlusal plane to the BD and the OP to the AC. Comparison between RVG measures and intrasurgical estimates were performed using paired t-test. The radiographic measurements overestimated interproximal bone loss as compared to the intrasurgical measurements: CEJ-BD measurement by 3.492 [P +/- 3.589 mm and intra-surgically was 6.492 +/- RVG was 6.803<0.000]. No statistically significant difference was seen between CEJ and occlusal references in RVG measurements [P<0.729]. Radiographic assessment by either the CEJ or occlusal references overestimated bone loss as compared to the intrasurgical gold standard

ABSTRACT

Statement of Problem: Dental caries is one of the common diseases in the world. It is an infective disease which is caused by loss of minerals and destruction of dental tissues. One of the most effective ways to diagnose the interproximal caries is radiography. Bitewing radiography is the best way for caries diagnosis


Purpose: The aim of this study was to evaluate the prevalence of the interproximal caries in dental students of Islamic Azad University


Materials and Methods: This research was a cross sectional study that was conducted on 89 students of the Azad University consisting of 48 females and 41 males who were selected by random sampling. For each individual student left and right posterior bitewing radiographs were taken with a standard method [the interproximal spaces were between 6- 7, 5, 6 and 4, 5]. Thus 12 interproximal spaces were examined in each individual. The most proximal cavitation surfaces were detected in the upper Jaw


Results: Results revealed that 6 individuals [6.7%] were totally caries free and 83 individuals [93.3%] showed interproxmal caries. Out of 1068 proximal spaces which had been studied 794 Spaces [73.4%] were caries free and 274 surfaces [25.7%] had caries


Conclusion: The high incidence of proximal caries and the possibility of missing them in the routine examinations make the bitewing radiographs an effective procedure for diagnosis

ABSTRACT

Background and aim: in dental radiographic, except teeth and adjacent tissues, other neighboring organs can be exposed to X- ray radiation, bringing about some problems for patients. The goal of the present study was to assess the rate of radiation absorption in thyroid gland and eye lens by trophy panoramic radiograph [Odontorama PC]


Materials and Methods: this study was performed on 50 cases [29 males and 21 females], using pocket dosimeter. One dosimeter was stuck on thyroid gland and the other one was stuck parallel to the plane passing through the lenses. A panoramic radiograph was then taken and the numerical amounts were read by two observers and printed on a questionnaire. A comparison was made between the radiation coefficients of thyroid gland and eye lens using t-test and the correlation between these two coefficients was calculated by persons' correlation coefficient


Results: the estimated mean amount of radiation absorption was 41.7 micro gray in thyroid gland and 6.67 micro gray in eye lens


Conclusion: considering the sensitivity of thyroid gland and eye lens to X-ray radiation, using lead collar shield and apron are suggested
