Active clinical trials for "Dental Caries"

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.

The importance of fluoridated water to control caries is well recognized. Although the mode of action of fluoridated water is known (related to a slight increase in fluoride concentration in saliva/dental biofilm in individuals living in fluoridated areas), the kinetics of fluoride concentration in saliva after ingestion of food prepared with fluoridated water, either from fluoride remaining in the oral cavity after mastication, or from fluoride returning from salivary secretion is not known in details. Therefore, the aim of this study is to assess fluoride bioavailability after ingestion of food prepared with fluoridated water. The study will be in vivo, crossover and double blind, in which 12 adult volunteers will participate. In 4 experimental phases, volunteers will ingest: a. a typical Brazilian meal cooked with non-fluoridated water (<0.1 ppm F); b. a typical Brazilian meal cooked with fluoridated water (1 ppm F); c. non fluoridated water (<0.1 ppm F) and d. fluoridated water (1 ppm F). Immediately before and 5, 10, 15, 30, 45, 60, 120, 180 minutes after the ingestion, a blood sample will be collected by digital puncture, and a sample of unstimulated saliva will be collected. Fluoride concentration in the samples will be determined by an ion specific electrode adapted for microanalysis. Results will be analyzed by ANOVA, with significance limit of 5%.

The hypothesis to be tested is that NuSmile ZR esthetic primary molar crowns perform similarly to an established Stainless Steel primary molar crown (3M ESPE) for restoration of primary molar teeth.

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.

The objective of this study is to explore if light cured resin modified Calcium silicate could result in better clinical and radiographic success if compared to light cured Calcium hydroxide when used in indirect pulp capping treatment in primary molars.

This study aims to compare the ability of different regenerative protocols in the treatment of mature necrotic

A comparison of caries detection rates between conventional intraoral bitewing radiography and a stationary intraoral digital tomosynthesis (s-IOT) using a carbon nanotube X-ray source array. The secondary objective is to assess participants experience with the s-IOT device.

The aim of this study is to evaluate the clinical performance of Filtek Bulk Fill Posterior Restorative in Class I and Class II restorations compared to the conventional incremental technique using Filtek Z350XT over the period of 2 years. The null hypothesis of this study is that the bulk-fill composite will exhibit same result and clinical performance as conventional composite using incremental technique which has been used widely by dentists nowadays.

This study is conducted to determine if using a mouthwash containing propolis, clove oil and chlorhexidine will improve the caries risk of high risk patients in comparison to using a mouthwash containing chlorhexidine only.

a double-blind cross-over in vivo study was performed to measure the salivary concentration of Xylitol released from the two chewing gums containing different amount of the polyol. The study had a cross-over design: the first half of the sample used the chewing-gum with Xylitol as the only sweeteners (64.5% of chewing-gum weight) and the other half use the chewing-gum with Xylitol among the sweeteners (22% of chewing-gum weight), after a 7-days wash-out period, the two sub-groups inverted the chewing gums. Subjects were instructed to consume the products as they normally would be consumed.
