Filter by:The present study will be the first to compared dental plaque quantitation between an oscillating-rotating electric toothbrush and a manual toothbrush with a new QLF technology.
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 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: 1. 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 2. 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 3. 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) 4. 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 : 5. 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 : 6. To assess patient's feelings about the use of each intra oral cameras 7. 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
We are studying the possibility of using dental calculus as a reservoir for the genes of an infectious agent that has infected the patient in previous months; as it is done to highlight climate change in ice samples.
