Filter by:This randomized double-blind two arm controlled clinical trials evaluates the hypothesis that the regular use of a tooth paste containing microcrystalline hydroxylapatite provides a caries preventive effect in caries-susceptible individuals undergoing orthodontic therapy with fixed appliances which is comparable to the caries preventive effect provided by the regular use of a fluoridated tooth paste.
Today's increase of dentate elderly, many of them dependent, is a challenge, both according to the personal daily oral hygiene and dentistry. This is not only an oral problem, as research findings point to strong associations between oral and general health, even mortality. These findings are especially noticeable in elderly and frail individuals. Dental care is usually performed in stationary dental clinics where the patients are transported to receive treatment. Dependent elderly dental patients may present many obstacles to traditional dental care due to cognitive limitations or dementia, mobility or transport problems. An alternative is domiciliary dental care where the dental staff performs the treatment by a home visit, in the patients daily living environment. The ability to handle personal oral hygiene is often decreased in these patients and left to overburdened nursing staff that often also lack sufficient knowledge about oral health care, why prophylactic professional oral care is especially important. This type of care can with rather simple equipments be performed as domiciliary treatment of good quality, while more advanced dental care may present restrictions in the home environment. However, in the Swedish dental system with subsidized dental care for dependent and elderly patients, there are restrictions for the number of prophylactic oral care treatments. The levels vary in different counties and regions. The rationale for this is probably tradition and economy as scientific evidence is lacking. The aim with this project is to develop domiciliary professional oral care. The researchers will compare the effect of different regimens for domiciliary prophylactic professional oral care both according to content and frequency. The overall aim is to establish relevant recommendations for domiciliary prophylactic professional oral care.
The purpose of this split-mouth, randomized, controlled trial is to evaluate the retention rates of sealants placed under Isolite vs. cotton roll isolation. This study will also compare the patient and operator acceptability and satisfaction of the two isolation techniques as well as the time consumed for sealant application during the two isolation techniques.
The main goals of this pilot study are to develop a nursing home-customized oral hygiene protocol, intended to be delivered primarily by dental hygienists and primary care providers, and to identify potential obstacles and barriers to overcome in designing a subsequent definitive study on the same topic.
The purpose of this randomized clinical trial was evaluate the performance of two conventional glass-ionomer cements in the pit and fissure sealing and atraumatic restorative treatment in high caries risk children.
The aim of this study is to validate a near-infrared light transillumination device (DIAGNOcam, KaVo, Biberach, Germany) for interproximal enamel caries detection and compare it with the established diagnostic methods (visual examination and bitewing radiography). The aim is to avoid/reduce ionizing radiation for caries diagnostic purposes.
This retrospective cohort study assessed sealant clinical success applied to pit and fissure by dental undergraduate students at Piracicaba Dental School - Brazil.
The purpose of the study is to confirm the safety of Advantage Anti-Caries Varnish.
This study mainly compared the response of the artificial carious enamel lesions to remineralisation in situ. The tested in vitro demineralising protocols were: MC gel, PA gel, MHDP and Buffer solutions. The lesions were then remineralised in an in situ model, with crossover and double blind design. Fifteen volunteers wore intra-oral appliances containing 2 bovine enamel samples of each demineralising protocol during 3 experimental phases (3 days each). The experimental phases/treatments were: Control (Placebo dentifrice, saliva effect only), Home-care (fluoride dentifrice, 1,100 ppm F, NaF), and Professional/Home-care (varnish- 22,600 ppm F and dentifrice- 1,100 ppm F, NaF). During the 3-day phase, the appliance was only removed during the main meals (four times a day, maximum 1 h duration each, interval between meals 2-3 h). Immediately after the meals, before replacing the appliance in the mouth, the subjects were advised to perform oral hygiene using a soft end-rounded toothbrush (Colgate® 360º Sensitive Pro-Relief TM) and dentifrice (non-fluoridated from IceFresh, Bauru, SP, Brazil or fluoridated dentifrice from Crest Procter & Gamble, Cincinnati, OH, USA) according to the phase and dental floss (Sanifill, São Paulo, Brazil). The remineralising treatment with dentifrices was done ex vivo, 1 min twice a day (after the first and last oral hygiene of the day) using slurry of the dentifrice (1:3 water, 1 drop of solution/specimen). Thereafter, the appliance was replaced in the mouth and the subjects were advised to rinse with 10 ml of water for 5 s and to expectorate. In respect to Professional/Home-care phase, the varnish (Duraphat, Colgate, SP, Brazil) was applied before the in situ study for 6h and then removed. The enamel remineralization was quantified using transverse microradiography (% mineral recovery and lesion depth, TMR), surface and cross-sectional hardness. The data were submitted to statistical analysis (p<0.05).
At present, dentistry aims for conservative treatments with the goal of maintaining as much tooth structure as possible. Dental caries remains the most prevalent chronic disease worldwide; these lesions can progress rapidly and reach deeper areas of the tooth. The carious lesion is considered deep when it goes through the main tissues of the tooth, and it can affect the pulp tissue, where the nerve and nutrients of the tooth are located. There are many treatment options for deep carious lesions and they vary by the clinical scenario. Vital pulp therapy has become a fairly predictable alternative treatment to pulpectomy (root canal therapy). The goal of vital pulp capping therapies is to keep the pulp of the teeth vital to prevent further interventions such as root canal treatments and complex restorative work. There are two main clinical scenarios when treating these lesions, depending on the remaining dentin thickness between the carious lesion and the pulp: vital direct and indirect pulp capping. Direct and indirect vital pulp therapies are routinely performed using different clinical protocols. The clinical protocols are selected based on the remaining dentin (between the tooth preparation and pulp) and the restorative materials. There are few studies that evaluate pulp capping method in adult teeth (permanent dentition); many studies have investigated baby teeth (deciduous teeth). Routine therapies include the using of adhesive restorations with and without an intermediate layer of restorative material. Calcium hydroxide based cements have been used for pulp capping as an intermediate layer of restorative material. More recently a new intermediate layer of restorative material composed of resin-modified calcium silicate has been indicated for use on direct and indirect pulp capping. The aims of this study are to compare, over a period of 12 months, the post-operative sensitivity and pulp vitality of three indirect pulp capping protocols and two direct pulp capping protocol in vital teeth. This study will provide the necessary evidence to allow clinicians to select the best restorative protocol when treating deep carious lesions where indirect and direct pulp capping protocol are needed.
