Filter by:The study was to monitor effectiveness of glass ionomer sealant and resin-based sealant in ICDAS, and to evaluat the correlation between ICDAS and DIAGNOdent over 24 months. Over 200 8-year-old children with at least 2 permanent molar with the International Caries Detection and Assessment System (ICDAS) scores 0-4 were placed glass ionomer sealant and resin-based sealant split-mouthed randomly, and examined with ICDAS and DIAGNOdent before sealents placement and 6, 12 and 24 months after.
Crown lengthening surgery is done when a tooth needs to be fixed with a crown. Sometimes, not enough of the tooth sticks out above the gum to support a crown. This can happen when a tooth breaks off at the gum line, or when a crown or filling falls out of a tooth and there is decay underneath. To place a crown, the dentist needs to expose more of the tooth. This is done by removing some gum tissue or bone. After surgery, the area will heal in about three months. Then, making a crown can begin. This healing period often delays the delivery a final crown. This study is investing a way to make the final impression at the surgery to expedite the delivery of a final crown.
The present study aims to evaluate, through a controlled clinical randomized study,the effectiveness of silver diamine fluoride in arresting dentin caries lesions in primary molars when compared to atraumatic restorative treatment.
The purpose of the study is to determine the effect of a two-step mouth rinsing procedure on reducing the germs (mutans Streptococci) that cause tooth decay. We hope that the two-step mouth rinse (0.3% NaOCl followed by 10% Povidone Iodine) decreases the tooth causing germs better than the one-step mouth rinse (10% Povidone Iodine). The mouth rinse for both treatment groups is done only once at the beginning of the study after the initial saliva samples are taken, and before a detailed examination of the teeth and gums. It is hypothesized that the treatment group receiving the NaOCl and Povidone iodine will have significantly lower microbial counts than the control group (Povidone iodine) because the NaOCl will disrupt the microbial biofilm and make the Povidone iodine more effective in decreasing the microbes in the biofilm. Microbial counts are made from Salivary samples taken from participants at baseline, one week, one month, two months and three months. The samples are tested by two commercial methods for determining microbial counts. The CariScreen Test is a rapid bioluminescence assay that quantitates the total number of all of the organisms present. The CRT test requires a culture media that is specific for the two germs (S. mutans and Lactobacillus) strongly associated with tooth decay. The results of the CRT Test are read after three days of incubation.
Chlorhexidine is the most potent chemotherapeutic agent against mutans streptococci and dental caries, however, the incidence of side effects such as teeth discoloration, staining of restorations, undesirable taste, discoloration of tongue, dryness and burning sensation in the mouth discourage patients to use this mouth wash. Natural products are now preferred by a large proportion of the population and have been reported to possess antimicrobial activity.These products have recently been shown to be a good alternative to synthetic chemical substances for caries prevention like Cinnamon and Ginger. The aim of this study is to compare the antimicrobial effects of aqueous extracts of cinnamon 20% and ginger 20% in comparison to chlorhexidine gluconate 0.2% on oral streptococcus mutans
36 eligible participants will be randomly divided into three groups (n=12) according to the tested chewing gum (A), where (A1) represents participants exposed to xylitol chewing gum, (A2) represents participants exposed to bicarbonate and xylitol chewing gum and (A3) represents control group where participants are exposed to paraffin pellet chewing. The pH of saliva will be evaluated according to time in relation to the gum chewing (T) where (T0) represent the pH before chewing, (T1) represent 5 minutes after gum chewing at fixed time of the day (in the morning from 10 to 11 am). Direct benefit of the research to the human volunteer: It is important for high caries risk patients to decrease caries susceptibility as this will eventually decrease their dental treatments and subsequently the treatment cost. Scientific value and social benefits: This study will benefit the dentist as the main goal of a dentist is to prevent rather than cure. Also, it will decrease the restorative work carried out by dentist and save this time for educating more patients about caries prevention methods. Expected risk to the human subjects: Allergic reactions due to any of the components of the materials used which is rare to occur.
This is a randomized controlled trial of regular daily use of xylitol (or "birch sugar"), a natural sweetener that has antimicrobial properties, for the prevention of acute otitis media (AOM, primary outcome) as well as upper respiratory tract infections and dental caries (the two secondary outcomes) in preschool aged children. This trial will be conducted through the TARGet Kids! research network.
Single-blind study to evaluate whether C16G2 Strip administered in multiple doses can effectively kill the bacteria in the oral cavity that cause dental caries..
1. Three dentinal carious lesions will be chosen in this study and will be in the same patient. 2. Using local anaesthesia and rubber dam, the operative field will disinfected with 1% hypochlorite, and the dentine lesions should be exposed with a high-speed diamond bur by removing covering enamel. 3. Before the excavation dentine samples are collected for baseline bacteriological assessment . 4. Excavation will be carried out using new slow speed round burs and hand excavators. 5. The excavation end point of one cavity will be determined using visual tactile method. The two other cavities will be inspected with fluorescent camera or caries detector dye (CDD) methods to determine excavation endpoint respectively. 6. After excavation, dentine samples from the three cavities will be collected using a sterile excavator for the bacteriological assessment. - Number of visits & follow up period: all procedures will be done at the same visit and there is no follow up period. Direct benefit of the research to the human volunteer: to determine the excavation endpoint to ensure complete caries removal and prevent it's recurrence in the future. Scientific value and social benefits: to reach the best method to determine the excavation endpoint. Expected risk to the human subjects: the ordinary side effects associated with any restorative treatment and no of the study variable has side effect on the patient and in case of any side effect due to the restorative treatment, the participant will directly contact the operator.
Swedish Quality Registry for dental health care (SKaPa) is a national registry that has since year 2008 gathered dental data. The data is automatically extracted from the patients' electronical dental data records. A vast majority of the public dental health care clinics deliver data on a daily basis (SKaPa, 2013). SKaPa has the purpose to improve and develop the quality of care and patient outcomes for both prevention and reparative/restorative methods concerning caries and periodontal disease. For children and adolescents, it is above all information related to dental caries that is collected (SKaPa, 2013). So far, SKaPa has published seven annual reports. In the report for year 2013 a limited information about the status of children was given, due to uncertainty in the quality of the information that is passed on to SKaPa (SKaPa, 2013). There is therefore a need to examine the validity of the data supplied to SKaPa. Tooth decay is the most common disease in children and adolescents that often lead to invasive interventions and pain. There are reports of great social disparities in dental health in children and adolescents in Sweden (The National Board of Health and Welfare, Socialstyrelsen, 2013). Because tooth decay is a common disease in children, it is important to be able to monitor the occurrence of the disease and also examine how it differs across various groups of children and adolescents. This is now possible through the several registries that are available in the dental and health care. Register-based research will be an important tool to ensure that children and adolescents receive oral health and dental care on the same premise as others, provided the data in the registries are valid. Furthermore, register-based research is important for development and quality assurance of dental care.
