Active clinical trials for "Dental Caries"

The objective of this randomized control cinical trial will be to compare the effectiveness of precured composite inserts in obtaining tight and adequate conatacts in class 2 restorations when compared with the contact making instrument technique among patients treated at the operative depatment of Foundation Umiversity College of Dentistry. This is a single centre based randomized control clinical trial in which intervention arm 1 will get there class 2 restoration done with precured composite inserts and interention arm 2 will recieve treatment with contact making instrument technique. The control arm will recieve restoration using the conventional composite layering technique.

This study will investigate the clinical performance of a novel restorative glass ionomer (DeltaFil, DMG) in comparison to an established restorative glass ionomer (Riva Self Cure HV, SDI) in the restoration of Class II cavities in primary molars.

To assess post operative pain and survival rate after collagen based pulpotomy versus MTA pulpotomy in children with vital primary molars.

This study will be conducted to evaluate and compare the clinical performance of fluoride, calcium, and phosphate-releasing new bioactive material versus a fluoride-releasing hybrid restorative material in cervical lesions for one-year follow-up. The clinical evaluation will be done using modified USPHS criteria at baseline,3,6,9 and 12 months.

The goal of this [type of study: Randomized clinical trial] to compare the clinical performance of using glass ionomer with advanced glass hybrid technology (AGH) in cervical carious lesion, versus Resin modified glass ionomer (RMGI) using esthetic and mechanical properties according to FDI criteria over one year. in adult patients with cervical carious lesion. The main question it aims to answer are: • Will the use of glass ionomer with advanced glass hybrid technology, achieved through introduction of ultra-fine highly reactive glass and high-molecular weight polyacrylic acid powders within conventional glass ,or Resin Modified Glass Ionomer have better mechanical and estheic properties over one year in adult patients with cervical carious lesions ? Participants will be assessed for medical and dental histories first. Then an examination of the patients will be done using visual inspection by using a dental mirror and probe. Eligible patients according to inclusion and exclusion criteria will be informed about all procedures with follow up time if they accept, their signature on written informed consents will be obtained. Eligible participants will be randomly divided into two groups according to the type of restoration that will be received after class V cavity preparations for carious cervical lesions. Patients will be given local anaesthesia (Mepecaine - L Cartridges) as required, and the teeth will be isolated. A No. #330 bur (MANI, INC, Japan) in a high-speed hand piece with air/water coolant will be used to prepare class V cavity. Sharp excavators of suitable size were used to excavate soft carious lesions in dentin. the prepared cavity will be isolated with rubber dam. The first group (A) will be received resin modified glass ionomer restorative material and the second group (B) will be received advanced glass hybrid glass ionomer . Each restoration will be evaluated for clinical parameters after finishing and polishing at baseline and regular recalls of 6 months and one year. The restorations will be clinically examined according to FDI criteria criteria in terms of esthetic and mechanical properties . The information that will be obtained will be collected and statistically analyzed.

The aim of the study is to clinically evaluate the shade matching and clinical performance of the Universal shade composites Omnichroma and GC Essentia versus the multi shade composite Filtek Z350XT in restoring cervical lesions of anterior teeth.

the aim of present study is to evaluate clinically the fracture liability , marginal adaptation , and patient satisfaction of conservative versus conventional ceramic Onlays use e-max press to restore defective restored molar with old restoration or caries. with one or more cusp defect

This randomized clinical study aims to evaluate the clinical performance and occlusal wear resistance of nano-zirconia reinforced glass ionomer restorations in comparison to Nano-hybrid resin composite in proximal cavities.

Class V carious lesions will be restored using two different restorative materials either Resin modified glass ionomer or nanohybrid resin composite lined by PRG barrier coat. Each restoration will be evaluated for clinical parameters after finishing and polishing at baseline, at 6 months, 12 months and at 18 months. The restorations will be clinically examined according to modified USPHS criteria in terms of retention, marginal adaptation, marginal discoloration, secondary caries and postoperative sensitivity.

This study will evaluate fluoride (F) bioavailability in saliva when using an over-the-counter mouthrinse of 226 ppm F, immediately after brushing with an over-the-counter toothpaste of 1,100 ppm F or a prescription toothpaste of 5,000 ppm F. The study population will include twenty individuals, over the age of 18 years-old, from both genders, with normal oral health conditions and salivary flow rate, no need of urgent dental needs, from the Ann Arbor, MI area. Participants will be recruited from the University of Michigan School of Dentistry, in Ann Arbor, MI. Using a crossover design, twenty participants will be rotating through 4 different combinations of fluoride toothpaste (over-the-counter or prescription concentration) and fluoride mouth rinse (yes or no), in a 2 x 2 factorial design. Treatments to be tested will be as followed: Group #1 will brush with 1,100 ppm F (over-the-counter) toothpaste; Group #2 will brush with 1,100 ppm F (over-the-counter) toothpaste and rinse with over-the-counter 226 ppm F mouthrinse; Group #3 will brush with 5,000 ppm F (prescription) toothpaste; Group #4 will brush with 5,000 ppm F (prescription) toothpaste and rinse with over-the-counter 226 ppm F mouthrinse.
