Filter by:This is a Phase III, randomized, one-center, three arm parallel group, open label and single blind clinical study to evaluate the effectiveness of a cognitive behavioral intervention (CBI) adjunctive to a smart powered toothbrush on the oral health of adolescents.
The aim of the research is to evaluate the clinical outcome of short dental implants, characterized by a new macro-structural design and inserted in the upper or lower jaw in patients with reduced bone volume. The clinical outcomes will be compared for different surface treatments of implant neck and those of prosthetic components.
Background The most common dental diseases are tooth decay (caries) and gum disease (gingivitis and periodontitis). Obviously, these diseases are caused by dental plaque (bacterial biofilm). Although most patients brush their teeth every day, they cannot keep all their teeth clean. Areas in the mouth that are difficult to access, such as crowded areas, posterior teeth or interdental areas, are usually affected (site-specific). After a thorough professional tooth cleaning, dental plaque will begin to accumulate on the tooth surface near the gum edge within a few days. Clinical studies indicating that regular disruption to the plaque is needed and can prevent and arrest gum disease. However, dental diseases may take years to develop, the patient usually does not have any pain symptoms unless the disease has progressed to the advanced stage. A significant amount of resources and clinical time have been used to motivate and instruct patients to keep their mouth clean and yet the results are not satisfactory. It is desirable to adopt an automated technique for monitoring oral health daily so we can seek treatment when it is needed. Patients' response to plaque accumulated at the gum margin is by inflammation which brings more blood cells to the site to fight against the bacterial invasion. Inflammation of gum is manifested as an increase in redness (color), an increase in volume (oedema), and loss of surface characteristics (stippling; gum fibre attachment). These affected areas can be identified by visual inspection with the dentist during the consultation or using intraoral photography. The objective of this research is to apply deep neural network technology to detect gum inflammation from intraoral photos. As the target inflammation site is at gum margin with varied shape and size, semantic segmentation at pixel level is needed. In this research, we are planning to have an extensive study of deep neural network (DNN) approach for the automatic multiple level gum disease detection. Standardized intraoral photography will be collected for 1200 cases and will be labelled by several dentists as "diseased" (inflammation), "healthy" or "questionable". Only gum area in which the dentists have same rating will be used to train/validate the system. Using the successfully developed system, one can use his/her mobile device to monitor their gum health when needed. They may be able to prevent the two main oral diseases (tooth decay and gum diseases) with minimal additional cost. It will be an important contribution to the promotion of public dental care. Aim of study This study aims to train and validate the computer to automatically monitor gum inflammation using standardized intraoral photos and selfie by smartphone. 1. to collect 1200 standard intraoral photographs and randomly cropped into training and validation sets. 2. to develop ground truth gingivitis label images into four health status levels (healthy, questionable healthy, questionable diseased and diseased) and verified by dental specialists. 3. to develop intelligent system for automatically detect inflamed disease sites with four health status levels. 4. to develop and standardize the image acquisition protocol for the detection with mobile devices. Hypothesis A diagnostic tool should be able to diagnose true disease and true health which described as sensitivity (positive when true disease) and specificity (negative when true health). The primary outcome will be the area under the receiver operating characteristic (ROC) curve (AUC). The hypothesis of this study is the trained gingival detection system is able to detect the changes of gum inflammation with high sensitivity and specificity.
The study aims to investigate the genetic cause of the variability between individuals seen in the development of the gum disease, gingivitis. This will be carried out through a 3 week programme where all oral hygiene is ceased, allowing 'experimental gingivitis' to develop, followed by a period of recovery when tooth cleaning is restored. Clinical assessments and biological samples will be taken during the course of the study for further analysis.
Orthodontic appliances can affect changes in the relationships of members of the oral microbiome. Microbiome imbalance can result in oral infections and complicate treatment. The focus is on the microbiological profile of dental biofilm and its control. The effects of metals released by corrosion of alloys for oral use on the microbiome and the extent to which they modify the effectiveness of gingivitis therapy by mechanical and chemical control of biofilm will be investigated. Early and late colonizers of the tooth surface will be analyzed. The condition of gingiva will be assessed, and the results will show the specifics of biofilm and gingiva exposed and unexposed, and differences in the response of individual bacteria to therapy. Molecular biology techniques will be used to quantify the total bacterial biomass (16s rRNA) and the proportion of specific bacterial species within the dental biofilm.
The purpose of this research study is to develop a better way of measuring the health of patients' mouth using photographs and imaging software. The investigators will also study the specific effects of individual toothpastes and mouthwashes on oral health. Participants who have volunteered to be in the study will be asked to use a toothpaste or over a period of 7 days to 6 months. The investigators will determine the participants' oral plaque levels, gum health, and saliva (spit) production with clinical exams as well as photographs of the participants' mouths. It is the hope of the study team to find better ways of assessing the health of patients' mouths and to identify whether gum health can be improved by specific toothpastes or mouthwashes.
This early-stage research is designed to determine the efficacy of the Lumoral method in chronic periodontitis patients. Improved supragingival plaque control can help to also sustain the subgingival plaque management in the long term. In addition, the device might have a photobiomodulation effect on periodontal tissues.
The present study aims to assess and compare the anti-plaque and anti-gingivitis effects of Moringa plant extract and Fluoride toothpastes among a group of Egyptian Children.
Objective: To evaluate the effectiveness of a gel containing nanovitamin C, nanovitamin E and propolis extract compared to a placebo in the treatment of desquamative gingivitis (GD) in patients with mucocutaneous diseases with gingival involvement. The possible improvement in the quality of life of these patients after treatment will also be evaluated. Study design: Double-blind, randomized controlled study. Patients: GD patients are being selected from the Postgraduate 'Specialist in Oral Medicine' of the Faculty of Dentistry, Complutense University of Madrid. Allocation: Patients are being randomly assigned to the study group (dental prophylaxis + oral hygiene instructions + use of propolis gel for 4 weeks) or to the placebo group (dental prophylaxis + oral hygiene instructions + use of placebo gel for 4 weeks ). Both the study gel and the placebo are being used for brushing their teeth and for application in areas with GD. Variables: The severity of the GD will be collected according to the scale of Arduino et al. 2017 and the periodontal variables (plaque index, probing bleeding index and probing depth). Pain during treatment will be recorded using a 10 cm visual analog scale (VAS). The quality of life in relation to oral health will be recorded using the Oral Health Impact Profile-14 (OHIP-14) questionnaire. These variables will be collected on day 0, 2 and 4 weeks after using the study gel or placebo.
