Active clinical trials for "Gingivitis"

Periodontitis is an immune-inflammatory disease affecting the supporting structures of the teeth. It is a disease of multifactorial etiology, with microbial, genetic, environmental and host factors involved, with the release of oxygen-free radicals by the inflammatory cells. Quercetin, have shown potential antimicrobial activity, lowering of inflammatory markers, cholesterol reduction and inhibiting bone loss. However, this data has largely been obtained from in vitro and animal studies, but data from human studies are limited.

Gingival diseases occur commonly in the global population and herbal products for its intervention have limited body of research evidence. This study to evaluate the clinical efficacy of 5% thymoquinone (TQ) gel as an adjunct to scaling and root planing (SRP) in patients diagnosed with gingivitis. OBJECTIVE: To evaluate the efficacy of 5% TQ gel using a novel liposome drug delivery as a topical application following SRP in gingivitis patients. DESIGN: Double-blinded, parallel, randomized controlled clinical trial. SETTING: Faculty of Dentistry, King Abdulaziz University, and Qassim University, Saudi Arabia

The aim of this study is to investigate the effectiveness of the use of a toothbrushing assisting mobile application in dental plaque removal and adherence to the toothbrushing routine, in preschool children (3-5 yrs old) when brushing with either manual or powered toothbrush. Objectives: To identify the effectiveness in dental plaque control in relation to the following parental characteristics: Sociodemographic (area of residence, average income, education level) Oral Health status Oral Health Literacy Parenting style Parental oral hygiene practices

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. to collect 1200 standard intraoral photographs and randomly cropped into training and validation sets. to develop ground truth gingivitis label images into four health status levels (healthy, questionable healthy, questionable diseased and diseased) and verified by dental specialists. to develop intelligent system for automatically detect inflamed disease sites with four health status levels. 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.

This study aims to assess and compare the effect of green tea mouthwash compared to chlorohexidine mouthwash in reducing gingivitis and plaque scores (in terms of plaque index and gingival index) in children with plaque-induced gingivitis.

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.

Gingivitis is a highly prevalent chronic bacterial disease in susceptible children, adults and the elderly, persisting for decades in subjects, and is an essential precursor of periodontitis. Several studies have shown periodontitis and subgingival P. gingivalis to be associated with increased C-reactive protein (CRP) levels and CRP has been implicated as a possible mediator of the association between periodontitis and several systemic diseases Limited data are available today addressing detrimental systemic effects of experimental or natural gingivitis as they have been rarely investigated. Results of various studies support the concept that gingivitis leads to systemic inflammation and that the level of systemic inflammatory markers increases proportionately with increase in gingival inflammation. It has also been seen that appropriate dental prophylaxis can also limit systemic markers of inflammation in subjects with natural gingivitis. Sex hormones have long been considered to play an influential role on periodontal tissues, bone turnover rate, wound healing and periodontal disease progression and can influence the cellular proliferation, differentiation and growth of keratinocytes and fibroblasts. Estrogen is mainly responsible for alterations in blood vessels and progesterone stimulates the production of inflammatory mediators. In addition, some micro-organisms found in the human mouth synthesize enzymes needed for steroid synthesis and catabolism. Sex hormones are neither necessary nor sufficient to produce gingival changes by themselves. However, they may alter periodontal tissue responses to microbial plaque and thus indirectly contribute to periodontal disease. (Markou). Till date, no study has been conducted assessing the serum hsCRP levels in females of reproductive age group with gingivitis. This study, thus, aims to assess the effect of scaling on serum hsCRP levels and periodontal parameters in systemically healthy women of reproductive age group with gingivitis.

The purpose of this study is to prove whether a fluoride/zinc lactate containing mouthrinse is able to reduce dental plaque and gingival inflammation in patients who have gingivitis when applied twice daily during brushing at home over a period of 12 weeks.

In this day and age, smartphones are occupying big portions of our lives. Expanding development of mobile applications focusing on delivering behavioral health intervention have intrigued us to know better about their efficacy. Hence the present study was conducted to determine the effectiveness of the Brush DJ app on improving the oral hygiene compliance of patients wearing fixed orthodontic appliances by assessing their gingival status. Null hypothesis: There was no difference in the gingival status and oral hygiene status of patients between verbal oral hygiene instructions and oral hygiene instructions using the Brush DJ app. Research hypothesis: There was a difference in the gingival status and oral hygiene status of patients between verbal oral hygiene instructions and oral hygiene instructions using the Brush DJ app

The purpose of this research is to determine the effects of a chewing gum containing dietary nitrate to your gingival and heart health. Dietary nitrates are commonly found in leafy vegetables and beets. The information learned from the study may help us further understand the interconnection of oral health and heart health. The study is looking for individuals who present with mild to moderate gum irritation or bleeding. In the study participants will be randomized into either a group that will use a chewing gum containing dietary nitrate, or use a placebo chewing gum during a three-week period. Participants in the study will have a simple gingival exam, x-rays if needed, and small samples of saliva and blood collected. All participants will also undergo a routine tooth cleaning. Participants will be asked to breathe in a tube to sample the levels of nitric oxide. Finally, participants will have their heart health measured with a device that is like a blood pressure cuff.
