Filter by:Evaluation of a new basic filling restorative material. In contemporary dentistry, clinicians have essentially three types of material choices for direct restorations: amalgam, resin composite, and glass ionomer restoratives. Due to the toxicity of mercury and the subsequent environmental problems, the search for alternatives continues and search into new composite restorative materials intensifies. Recognized disadvantages of tooth colored resin based restorative materials are as polymerization shrinkage, postoperative sensitivity and technical procedure complexity. Higher rates of occlusal wear and lower toughness are disadvantages of glass ionomer restoratives. Therefore, alternative materials are being developed to compensate the disadvantages of current contemporary tooth coloured restorative materials. Nevertheless, the search for simplification for restoring missing dental tissues introduced the "basic filling concept". This project aims to study the clinical performance of this new basic filling restorative material for Class I and Class II cavities. 80 patients are recruited to the project which is carried out at the School of dentistry, Istanbul Medipol University, Turkey.
Caries prevalence has declined significantly since the introduction of fluoridated toothpastes. Since then, different toothpaste formulations and concentrations have been introduced to the market with varying levels of efficacy. There are several commercially available toothpastes to choose from and only with the aid of sound methodological research, can the best evidence-based oral education advice be delivered. This is a double-blinded randomised controlled trial that aims to measure the salivary fluoride concentration following tooth-brushing with several toothpaste formulations. Power calculations were performed using PASS 11.0 software, and calculations showed that 3 participants are needed in each group in order for results to be considered as significant. We will aim to recruit five to seven participants in each of the 12 groups. Research will be publicised by means of flyers and circulating emails amongst University of Leeds students. Information sheets will be provided to all participants and informed consent will be obtained. Each participant will brush with one of 6 different formulations of toothpastes either with or without water rinsing post-brushing. Participants will randomly be assigned to groups using an online random team generator. Saliva will be collected six times once before brushing and at 1, 15, 30, 60 and 90 minutes post-brushing. Samples will be analysed using fluoride ion-specific sensitive electrode connected to an ion analyser. A statistician's help will be sought for analysis of the results. After the analysis stage, the codes of the toothpastes will be broken.
The purpose of this study is to compare standard fillings and silver diamine fluoride (SDF) for treatment of cavities in baby teeth. The investigators will compare the effectiveness of stopping the cavity, cost of the treatments and the opinions of the families and the dental providers.
Background: Dental caries is considered an oral health problem worldwide. In Chile the last national epidemiological study (2007) showed a national prevalence of dental caries in children 6 years (70.3%) and 12 (62.5%). Direct pulp capping is a preventive dental therapy, keeps the vitality of the tooth using some inductive materials mineralized tissue formation. Objective: The main objective of this study is to evaluate the effectiveness of two innovative direct pulp capping materials; Biodentine compared MTA and calcium hydroxide in the maintenance of pulp vitality in teeth permanent molars.
The aim of the present study is to evaluate the clinical performance of EQUİA restoration material in Class II cavities comparing with a resin-based composite / dentin bonding system.
To elucidate the relationship of chewing miswak sticks on the H. Pylori infection in the oral cavity.The study would be conducted at the Faculty of Dentistry, Kuwait University. Oral plaque samples would be obtained from those patients who are willing to participate. As a part of the initial screening the plaque samples would be collected and sent for screening of oral microbiota to the Microbiology Department of Faculty of Dentistry, Kuwait University. Here, the basic microbial culturing (rapid urease test) would be performed for detecting the presence of oral H.Pylori. Volunteers who are tested positive for H. Pylori infection through the rapid urease test would be invited to participate in the study.
This is a three arm randomized trial. The aim is to evaluate the antimicrobial activity of chlorhexidine and polyhexamethylene biguanide oral antiseptics on the microorganisms of the oral cavity. A total of 30 healthy volunteers will be enrolled and randomly allocated to control group (CG, n=10), which will be instructed to rinse the mouth with 10ml of a sterile saline solution for one minute, to chlorhexidine group (ClG, n=10), which will be instructed to rinse the mouth with 10ml of an 0.12% chlorhexidine solution, for one minute, or to polyhexamethylene biguanide group (PG, n=10), which will be instructed to rinse the mouth with 10ml of an 0.07% polyhexamethylene biguanide solution, for one minute. Samples of saliva will be collected before the mouth wash and after 30, 60 and 180 minutes. Samples will be plated on manitol agar, mitis salivarius agar, EMB agar and Sabouraud agar. Samples will be processed by a blinded microbiologist.
The aim of this project was to compare the effectiveness of experiential learning (EL) and traditional lecturing (TL) school-based oral health education on the oral health knowledge, attitude, habits, oral hygiene, gingival health and caries incidence of 10 and 13-year-old Greek children. Thee hundred and fifty children were selected from three areas of Greece. Information on oral health knowledge, attitude and behaviour were obtained using a questionnaire. Dental plaque was recorded using a modified hygiene index, gingivitis was assessed using the simplified gingival index and dental caries was measured by recording the number of Decayed, Missing and Filled teeth (DMFT) using the British Association for the Study of Community Dentistry (BASCD) criteria. All children were examined by two calibrated dentists, using a World Health Organisation (WHO) periodontal probe and artificial light. Questionnaires were delivered and clinical examinations were performed at baseline and at 6 and 18 months post-intervention. The EL oral health educational program was implemented by teachers using the program's manual.
Cervitec, a chlorhexidine based varnished has been proven to reduce caries risk in younger populations. This study wants to investigate if the use of this product would reduce the risk of losing abutment teeth on patients that are wearing partial dentures as the literature has proven that these teeth are more prone to caries and periodontal disease. The primary objectives of this research project are to: 1. Assess if the topical application of CHX/thymol varnish every three months on partial denture abutment teeth results in a clinicallu significant decrease in any loss of attachment compared to no application, and 2. Assess if the topical application of CHX/thymol vanirhs every three months on partial denture abutment teeth results in a clinically significant decrease in carious lesion development or progression compared to no application. The secondary objectives of this research project are to: 1. Assess of the topical application of CHX/thymol varnish every three months on partial denture abutment teeth compared to no application results in a clinically significant difference in: 1. Bleeding on probing (BoP). 2. Plaque formation. 3. Periodontal pocket depths. 4. Microbial composition and GCF cytokine profile of the sub gingival environment. 5. The patients self perception of oral health.
The study is to compare the prophylactic and therapeutic clinical effectiveness of two fluoride varnishes in children at high caries risk. It was hypothesized, the use of Fluor Protector S (I) fluoride varnish in children with deciduous teeth at high risk of caries (P) reduces caries and the activity/remineralisation of carious enamel spots (transformation of White Spot Lesion into D (decay)) (O), similarly to what occurs after the use of Duraphat varnish (C).
