Active clinical trials for "Dental Plaque"

The purpose of this cross-over clinical research is to evaluate the cleaning efficacy of toothbrushes tufted with two types of tapered bristles and end rounded bristles in removal of interdental plaque with clinical measurement (Plaque Index) and objective measurement (digitally measured plaque area). This study will demonstrate the influence by a type of processing bristles on removal of interdental plaque and determine an agreement between the different evaluation methods. This is a randomized evaluator-masked crossover study with 10 subjects. Subjects will be randomly allocated to three test groups. Subjects will use the assigned toothbrush at baseline appointment and two times a day for a week. Plaque Index and plaque area will be assessed before/after one time use at baseline and Day 7. Subjects will be assigned to another toothbrush after one week wash-out period.

This study aims to investigate the impact of a bromelain pre-rinse adjunct on oral plaque removal in orthodontic subjects. The study's null hypothesis states that there is no statistically significant difference in visual plaque scores among orthodontic subjects with or without proteolytic enzyme rinse aid.

The objective of this research is to evaluate the oral modifications caused by different types of coke drinks (regular coke and diet coke). The salivary and the dental biofilm pH will be determined in the first minutes after their consumption. Additionally, the bacterial proliferation of dental biofilm will be evaluated.

Dental caries is a decay process that breaks down the tooth. The earliest clinical signs of active dental caries is seen as 'white spot lesions' (WSLs). WSLs causes porosity below the tooth surface as a result of demineralization that gives the lesion a milky white appearance. Many WSLs persevere even a decade after orthodontic appliance removal and remain a cosmetic problem. After removal of fixed appliances, a considerable improvement of WSLs can be seen during the first 6-24 months, but the degree of improvement varies between individuals. Two common bacteria in dental plaque causes caries: Streptococcus mutans (SM) and Lactobacillus acidophilus (LA) in the plaque contributes to the initiation and progression of caries, respectively. A major strategy suggested to deal with existing WSL after debond is to facilitate remineralisation using remineralising agents that contain fluoride. This can be from daily use of fluoridated toothpastes or having additional dose of fluoride application. Certain agents also contain casein phosphopeptide-stabilize amorphous calcium phosphate (CPP-ACP) that is believed to have an antibacterial and buffering effect on plaque and interfere the growth and adherence of bacteria.

Chlorhexidine is the gold standard of dental plaque prevention. Recent research have demonstrated that 0.2% Chlorhexidine solutions are more effective than 0.12% and 0.06% Chlorhexidine solutions. Several 0.2% solutions are available on the market. This study aimed to compare effectiveness of two commercially available 0.2% chlorhexidine mouthwashes. Patients, that after initial periodontal therapy, had a need for two periodontal surgeries, will be invited to join. After one surgical session, the patient will receive one 0.2% chlorhexidine solution, and after the next surgical session the patient will receive the other 0.2% chlorhexidine solution. Plaque and gingivitis will be recorded, as well as side effects.

This study aims to investigate the changes in saliva and dental plaque pH after consuming sugar-free chewing gum containing 5% of aqueous propolis in children aged between 8-11 years. The studied sample will be divided into two groups: Group A (Control group) placebo chewing gum, and Group B (Experimental group) aqueous propolis chewing gum. All children will experience both types of chewing gum with an interval of 1 week between the two studied groups.

Randomized Controlled Trial: to investigate the feasibility of the usage of a mobile dental application in the self-administration of plaque control in a two (2) parallel arm study with 52 subjects (n = 52). The study will take place over 2 visits (within 35 days): Visit 1 and 2. Prospective Open Cohort Study: Patients referred to the Periodontology Department will be invited to participate in the study during the Oral Hygiene Phase. Routine clinical indices will be recorded at Visit 1 and Visit 2 before active non-surgical periodontal treatment commences.

The purpose of this study is to assess if a propolis solution is able to remove plaque and kill microbes from complete dentures. The investigators will compare the results of the propolis-based denture cleanser with those obtained with an inactive solution.

The purpose of this study to investigate attitude, oral health literacy and psychological factors in order to evaluate if these factors are important for oral health in adults. The hypotheses are: Multiple interactive demographic, and social and psychological factors contribute to the level of attitude and oral health literacy. There is an association between the level of oral health literacy and oral health status A structured intervention based on oral health literacy can change the attitude and improve the oral health status. Background knowledge has influence on attitude and oral health literacy Individuals with positive attitude towards dental health and dentist are attentive towards their oral health.

The purpose of this study was to use the principle of fluorescence to identify oral diseases not readily visible to the naked eye. A imaging device with a removable and modular head consisting of arrays of Light Emitting Diodes (LEDs) with differing wavelengths (405nm,450nm or white) was used to image teeth to detect fluorescent biomarkers such as porphyrins associated with poor oral health (plaque). The process utilizes illumination of the teeth and gums using a specific array of LEDs in the visible and near-visible spectrum and is non-invasive. Successful implementation of the device would provide proof-of- concept validation for its use as a safe, rapidly deployable solution to assess oral hygiene.
