Active clinical trials for "Dental Caries"

in patients with Class I Cavities, will the use of Zenit Nano Ceramic Composite restorations have similar clinical performance to conventional Ceram-X Nano Ceramic Composite restorations, evaluation of restorations will be done at baseline, six, and twelve months using Modified USPHS Ryge criteria.

All ceramic crowns are indicated in case of mild to moderate discoloration, restoration of traumatized or fractured teeth and abnormal tooth anatomy. The success of dental restorations is determined by four main factors: biocompatibility, aesthetic value, resistance to fracture and marginal adaptation. . An inadequate marginal fit may compromise the longevity of the restoration since cement film exposure to the oral environment can lead to its dissolution . . Polyetheretherketone (PEEK) is a polymer that has many potentials uses in dentistry. Polyetheretherketone (PEEK) can be used to support fixed dental prostheses. However, information about physio mechanical characterization is still scarce. Aim of the study: - The aim of this study is to evaluate the internal fit of milled BioHPP PEEK-based versus zirconia-based single crowns.

To evaluate the change of S. mutans and Lactobacillus spp. counts after all dental treatments were completed under general anesthesia and compare the groups in case of using probiotics and not using probiotics with the time for 6-months follow-up period.

This study was a randomized clinical trial lasting for 24 months in two study sites, Hong Kong (water fluoridated) and Guangzhou (non-fluoridated area). A total of 534 subjects will be recruited from elderly social centers located in different districts in the two study sites (260 & 274). Baseline clinical examination was conducted by a single calibrated examiner in the social centers using an intra-oral LED light, mouth mirrors and probes. Subjects were randomly allocated into two study groups and receive interventions accordingly. Follow-up examinations at 6-month intervals were carried out to assess the clinical outcomes, i.e. whether new root caries developed and whether the active root caries found at baseline become arrested. Results of this study could provide the much needed evidence to guide the dental professionals in Hong Kong and China, and possibly worldwide in deciding on the most appropriate intervention for the prevention and management of this common dental disease of the older adults.

The aim of this study is to determinate the influence of an alternative adhesive application protocol (i.e. consecutive application of an extra adhesive layer)on restoration longevity in primary molars.

A program of motivational interviewing plus enhanced community services in prevention of early childhood caries vs. enhanced community services alone for American Indian mothers and their children will reduce the childrens' decayed, missing, and filled tooth surfaces measure over a 3-year period.

This prospective clinical randomized controlled trial is established to compare the clinical, radiographic, and histological treatment outcomes between MTA and FC in pulpotomized human primary molars at 6, 12, 18, 24 month post-treatment and to test the hypothesis that Gray Mineral Trioxide Aggregate (GMTA) is a viable alternative to Diluted (20%) Formocresol (DFC) in pulpotomies treatment of human primary molars.

This study questions the interest of fluoride varnish dental application in preventing tooth decay in a population of institutionalised elderly people.

Children will be recruited from the pediatric dentistry clinic of Marquette University at their first or recall appointment and will be asked to fill a questionnaire regarding their dietary habits. Afterwards a dietary analysis will be performed using a computer software, developed for this study and dietary instructions will be given to the children.

This study is a randomized clinical trial lasting for 30 months. A total of 300 subjects will be recruited from social centres for elders located in different districts in Hong Kong. Baseline clinical examination will be conducted by a single calibrated examiner in the social centres using an intra-oral LED light, mouth mirrors and probes. Subjects will be randomly allocated into the three study groups and receive interventions accordingly. Follow-up examinations at 6-month intervals will be carried out to assess the clinical outcomes, i.e. whether new root caries has developed and whether the active root caries found at baseline have become arrested (remineralized and hardened) or not. Photographs of the arrested lesions will be taken to assess their colour. Results of this study will provide the much needed evidence to guide the dental professionals in Hong Kong and worldwide in deciding on the most appropriate intervention for the prevention and treatment of this common dental disease of the older adults.
