Active clinical trials for "Dental Calculus"

This study is about the assessment of two oral telemedecine tools compared to an intra oral clinical examination used as a reference among elderly persons living in nursing home. Our hyposthesis is that the diagnostic performance of the two devices will be similar. The main goal of the study is to assess the performances of two intra-oral cameras compared to an intra oral clinical examination to detect at least one decayed tooth. The secondary objectives of this study are : At patient's level: To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) at least one filled tooth, (ii) at least one missing tooth, (iii) gingivitis, (iv) an abscess, (v) dental plaque and (vi) calculous To assess the concordance between each intra oral cameras and the intra oral clinical examination in the evaluation of the number (i) of decayed teeth, (ii) filled teeth and (iii) missing tooth From video acquisitions of each intra oral cameras, to assess the inter-observer concordance for the diagnostic of each dental pathologies (presence of at least one decayed tooth, filled or missing) and periodontal (presence of gingivitis, abscess, dental plaque or scale) From video acquisitions of each intra oral cameras, to assess the inter-observer agreement of the number of teeth: (i) decayed, (ii) filled and (ii) missing At tooth level : To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) a cavity, (ii) a filled tooth and (iii) missing tooth In all patients : To assess patient's feelings about the use of each intra oral cameras To compare the time required for video acquisitions between each of intra oral cameras For patients with dental or periodontal pathologies observed during the intra oral examination: 8 To assess, 2 months after initial evaluation, the proportion of patients attended dental or periodontal care and for which an appointment with a dentist has been scheduled

The objective of the study is to evaluate the safety and efficacy of the home-use device Silk'n toothbrush (ToothWave) for the improvement in dental health through the reduction of plaque, gingivitis, and calculus.

Periodontal disease is amongst the most prevalent oral diseases worldwide and in North America. According to the 2007/09 Canadian Health Measures Survey, 16% of Canadian adults and 24% of older adults, 60 to 79 years of age, were found to have moderate periodontal disease. Moreover, 11% of Canadian adults were found to have calculus scores in the highest range. On the other hand, recent reports on the prevalence of periodontitis in the US showed that 47.2% of adults aged 30 years and older have some form of periodontal disease and 70.1% of adults 65 years and older have periodontal disease. The estimates also showed that the expenditure for periodontal treatments in the US is about approximately $ 14.3 billion. Since dental calculus plays an important etiological role in initiation and progression of periodontal diseases. Investigation and investment on preventive technologies to prevent the periodontal disease are important for any health care system and its end-users. Furthermore, the removal and prevention of dental calculus using an effective toothpaste could reduce the need for professional periodontal interventions or the time of these treatments that in turn reduces their cost and other burdens on patients. The aim of this study is to assess the efficacy of D-Tart toothpaste in removing dental calculus compared to Crest® (Complete Whitening plus Scope, tartar control, Procter & Gamble, Cincinnati, OH), anti-tartar toothpaste with similar pH and texture to D- Tart toothpaste.

The objective of the study is to evaluate the safety and efficacy of the home-use device Silk'n toothbrush (ToothWave) for the improvement in dental health through the reduction of plaque, gingivitis, and calculus.

The objective of the study is to evaluate the safety and efficacy of the home-use device ToothWave (Model H7001) for calculus reduction and the prevention of calculus accumulation.

The objective of the present study is to evaluate the surface texture of root after hand instrumentation with Gracey curette, After Five curette and Mini Five curette.Patients having chronic periodontitis and scheduled for extraction were randomized into four groups. Scaling and Root planing was performed by different curettes. Group 1 didn't under go any instrumentation. Group 2 was instrumented with Gracey curette, Group 3 with After Five curette and Group 4 with Mini Five curette. These hopeless teeth were then extracted atraumatically and the specimens were processed and analyzed under a Scanning Electron Microscope. "Roughness and Loss of Tooth substance index" and "Smear layer index" was evaluated using the Scanning Electron Microscope photographs.Means and frequencies were reported using SPSS Version-21.Cross Tabulation was made between the test groups (Control, Gracey Curette, After five and Mini Five) versus "Roughness and Loss of Tooth substance Index" and "Smear Layer Index". Chi square test was applied to see the grade distribution among groups. Frequencies were reported in percentages and means. P. value of 0.05 or less was considered as significant.

In this clinical study, it was aimed to evaluate whether there is a decrease in patient anxiety by applying virtual reality glasses, which are the product of new technology, during scaling and root planing treatment. Patients who required scaling and root planing treatment and also scored 9 or above according to the Dental Anxiety Scale were included in our study. Scaling and root planing was performed in a randomly selected intraoral quadrant of the patients, in the same way, with or without the use of virtual reality glasses. In the virtual reality glasses application, a video consisting of images of nature landscapes developed for patient rehabilitation was projected onto the screen in front of the patient's eyes. The Dental Anxiety Scale was reapplied after the completion of the treatment. In the intraoral quadrant where virtual reality glasses were used, it is expected that lower Corah Dental Anxiety Scale scores may be obtained after the treatment is completed, compared to the intraoral quadrant where the treatment is performed without glasses, thus reducing anxiety.

The presence of plaque on tooth surfaces as a predictor of chlorhexidine side effects has not been evaluated especially because most studies utilized a previous disruption of biofilms in all dental surfaces before the beginning of rinsing. The purpose of this study is to compare staining and calculus formation after 0.12 percent chlorhexidine between previously plaque-free and plaque-covered surfaces by means of an experimental gingivitis model.

To compare the diagnostic accuracy of extra-oral x-rays with intra-oral x-rays, in contrast to clinically observed measurements, for the detection of calculus and bone loss of either the suprabony or infrabony types in patients undergoing periodontal surgery.

This is an evaluation of potential differences in saliva composition and dental calculus composition between orally fed and tube fed individuals in an institutional environment.
