Filter by:The objective of this randomized, single center, parallel clinical research study is to evaluate the comparative efficacy performance of three dentifrices -Colgate Total Toothpaste, Parodontax Toothpaste and Colgate Cavity Protection Toothpaste in controlling gingivitis and dental plaque in adults.
The overall goal of this study is to improve the standard of care in treating young children who often suffer from chronic caries (dental decay). Current standard of care for children under 12 years old includes a dental cleaning and fluoride treatment. Often this dental cleaning includes a 'dental prophylaxis' with a pumice based paste delivered by a small rubber-like cup that rotates on a slow-speed dental handpiece. The procedure of this dental prophylaxis removes the gross levels of plaque around the supragingival tooth surfaces. After this prophylaxis, a fluoride treatment is delivered. The National Maternal and Child Oral Health Resource Center at Georgetown University has published (Bertness J, Holt K) an extensive publication proving that 5% sodium fluoride varnish has become the 'standard of care' for fluoride treatment in children. This study includes this fluoride standard of care. Prior to the administration of this standard of care fluoride treatment, a separate step of cleansing the tooth after the dental prophylaxis is added. This study uses a cleansing procedure of 10% povidone iodine (PI) cleansing prior to fluoride varnish (FV) application. The primary aims of this study are: 1. to measure the changes in overall plaque levels after using a 10% povidone iodine (PI) cleansing prior to fluoride varnish (FV) application. 2. to measure the short term changes in the oral microbial ecology of dental plaque after 10% povidone iodine (PI) cleansing prior to fluoride varnish (FV) application.
Purpose: The aim of this study was to compare the efficacy of dental biofilm removal by brushing with and without conventional toothpaste. Settings and Design: Twenty-four students aged 17 to 28 years old participated in this randomized clinical trial. Materials and Methods: Quadrants 1-3 or 2-4 were randomly allocated to the test group (brushing without dentifrice) or control group (brushing with dentifrice). After 72 hours of cessation of oral hygiene, Quigley & Hein (Turesky) plaque index was assessed before and after brushing by a calibrated and blind examiner. Overtime and intergroup comparisons were performed by paired sample t test.
The aim of this randomized, single-blind, split-mouth design, clinical trial was to evaluate the effectiveness in plaque removal of the vertical and the horizontal brushing methods. Trauma on soft tissues were also registered. Sixty-one (61) young adults were enrolled for this trial and forty-three (43) completed the brushing session. All subject were asked to abstain from oral hygiene procedures for 48 hours before the brushing session to allow adequate plaque accumulation. They were firstly instructed to use a dental disclosing tablet in order to easily permit to detect dental plaque on teeth and to highlight soft tissue abrasions. Plaque and the abrasion indexes were recorded according to the Rustogi Modified Navy Plaque Index (RMNPI) and the Danser Index (DI) by the same examiner. The brushing session was always performed by the same dental hygienist who brush with a randomized split-mouth design. After the brushing session, the blinded examiner recorded the indexes again.
The purpose of this study is to compare the effects of two new family-based oral health promotion programs with the routine program in use earlier in Vantaa public dental service. The children born in 2008 were followed from their first visit to public dental service at the age of 6-12 months to their dental examination at the age of 2-2½ years. The outcome measures are the colonization of mutans streptococci in dental plaque, dental caries, and the oral health habits of two-year-olds.
Background: - Dental plaque is a coating of bacteria on the teeth. It contributes to poor dental health and diseases such as gingivitis, cavities and periodontal disease. Researchers who study plaque know that many different types of oral bacteria stick to each other in test-tube experiments. However, it is not clear if these interactions occur in natural dental plaque. By studying how bacteria interact, researchers can better understand how bacteria come together and grow to form plaque. Objectives: - To look at how bacteria interact with one another to form dental plaque. Eligibility: - Healthy nonsmoking volunteers at least 18 years of age. Design: - Participants will be screened with a medical history and dental exam. They will also have dental impressions taken for a stent (a device similar to Invisalign(SqrRoot) braces). - Participants will wear the stent for up to 8 hours a day on selected study visit days. It will contain enamel chips made from sterilized human teeth. The mouth bacteria will stick to the chips and grow. Chips will be taken out of the stent twice during these study visit days. - Participants will have other study visits to provide saliva and plaque samples. They will also have gum swabs to collect bacteria. - Some participants may have a second set of study visits. At these visits, they will chew gum to increase their saliva production. Afterwards, they will wear the stent with the enamel chips for 4 hours. Samples from the stent will be taken once on these study visit days.
The purpose of this study was to compare the antiplaque efficacy of a 0,12% chlorhexidine and 0,05% cetyl-pyridinium chloride mouth rinse (Perio-aid®) with a 0,2% chlorhexidine non-alcohol base mouth rinse (Corsodyl Care®).
The purpose of this study is to determine the effect of three times a day mastication, during a follow-up period of 4 weeks, of two sugar-substituted chewing gums on various factors associated with dental caries and gingivitis.
The aim of this study was to determine whether rinsing with water or cleansing teeth after topical fluoride therapy affect the dental plaque pH.
This study will test the idea that using an experimental mouth rinse after each time you brush your teeth will result in a healthier mouth than using the regular mouth rinse. Participants will be expected to avoid oral hygiene (like brushing teeth or using mouthwash) for at least 12 hours before each visit and will not be allowed to eat, drink or smoke for at least 4 hours before each visit. At the first visit, the study will be explained to you in detail and you will be allowed to ask any questions you may have before signing a consent form. You will complete a medical/dental history and the dentist will examine your mouth, during which he will poke your gums and scrape some plaque off your teeth for testing. If you do not meet the requirements to continue in the trial, you will be told that you do not need to return for more testing. If you meet requirements to continue, you will have an equal chance of being assigned to use either of the two mouth rinses being studied. You will be given a diary, toothbrush, toothpaste, and your assigned mouth rinse, with instructions on how they must be used. You will be instructed not to use any unassigned oral care products and to follow your usual eating habits. You will be given appointments to return two times within the next four weeks. At those visits, the staff will check to make sure you're following the instructions and ask how you're feeling, and the dentist will do the same thing he did during the first visit.
