Active clinical trials for "Dental Caries"

The aim of this study was to investigate the clinical effectiveness of direct resin composite restorations placed with different placement techniques (incremental or bulk) and with different flowable linings (conventional or bulk-fill flowable) used in open-sandwich technique, in endodontically treated Class II cavities (mesio-occlusal or disto-occlusal), in a randomized controlled comparison.

Although selective removal of carious tissue to soft dentin (SRCT-S) has been proposed as the standard of care for the management of deep dentin caries, it is unclear whether a cavity liner is necessary. This double blinded randomized controlled clinical trial aims to analyze the behavior of a resin restoration performed after SRCT-S for deep dentin caries, treated either with a Glass Ionomer or only with a Self-Etching Adhesive, in permanent teeth. The study will include 142 restorations allocated to either experimental arm. After 12 and 24 months, restoration survival, pulp response and radiographic lesion progression will be assessed.

The study aim is to characterize the kinetics of silver and fluoride after topical application of silver diamine fluoride.

Aim of the study was to compare the effect of chemo-mechanical caries removal methods using Papacarie-Duo and alternative restorative treatment (ART) on the Oral Health Related Quality of Life (OHRQoL) of pregnant women.

The primary objective of this randomized controlled trial is to assess the effects of oral sedation using midazolam and hydroxyzine with and without meperidine (a narcotic) on sedation outcomes in pediatric dental patients undergoing dental treatment at the University of Washington Center for Pediatric Dentistry. Procedural sedation can be offered as an option for dental treatment for a young, potentially uncooperative pediatric patient to safely and effectively complete dental restorative needs. Both sedation regimens are already regularly used for patients at the UW CPD. The goal of this study is to assess if removing a narcotic from the regimen will produce the same behavioral success outcomes as a regimen with a narcotic. Our hypothesis is that patients who receive oral sedation using midazolam, hydroxyzine, and meperidine will experience fewer behavioral failures than those who receive oral sedation using midazolam and hydroxyzine without meperidine. The secondary objective of this project is to evaluate the relationship between child temperament and sedation outcome in each treatment group.

Objectives: to assess the efficiency of three methods of enamel remineralization on initial approximal caries: 1. a nano-hydroxyapatite gel, 2. gaseous ozone therapy 3. combination of a nano-hydroxyapatite gel and ozone. Materials and Methods: Patients (n=92, age 20-30y) with initial approximal enamel lesions on premolar and molar teeth (n=546) randomly allocated to three groups subjected to a 6-months treatment: Group I: domestic nano-hydroxyapatite remineralizing gel, group II: in-office ozone therapy, group III: both remineralizing gel and ozone therapy. Caries lesions assessed on bitewing radiographs at baseline, after 1 year and after 2 years.

Removal of infected dentin contaminated with bacteria and remaining affected dentin detected as firm is the conventional strategy for the management of cavitated caries lesions. Recently, this strategy is termed as selective removal to firm dentin (SRFD) and seems to increase the potential risk of pulp exposure or loss of pulp vitality for deep caries lesions radiographically extending ¾ of dentin tissue. Alternatively, selective removal to soft dentine (SRSD) that refers to removal of caries tissue at the periphery of the cavity to firm dentin and remaining caries tissue detected as soft or leathery in proximity with the pulp might be a less invasive excavation method for deep caries lesions to maintain pulpal health. However, information on clinical advantages or disadvantages of SRSD and SRFD excavation methods is sparse and mostly rely on studies conducted for primary teeth. Moreover, clinical trials are needed to demonstrate the combined effect of carious removal strategies and calcium silicate-based materials. The aim of this study is comparison of clinical success rates of SRSD and SRFD techniques in posterior deep caries lesions. The primary outcome of the study is comparison of clinical success of SRSD and SRFD techniques by clinical and radiographic examination after 3 months, 6 months, 1 year and 2 years. The secondary outcome of the study is to investigate whether or not calcium silicate-based materials have an effect on the success rate of the treatment.

This trial will be conducted to compare the clinical performance between a new bioactive resin composite material and high viscosity glass ionomer for restoring occlusal carious lesions of posterior teeth in patients scheduled for head and neck radiotherapy.

This randomized clinical trial evaluated the clinical performance of class II resin composite restorations using bulk-fill high-viscosity ormocer versus methacrylate-based with or without a thin layer of bulk-fill low-viscosity (flowable) resin composite liners (BLRC) over 2 years. The null hypotheses in the study were as follows: (1) Different types of matrix structures (ormocer vs. methacrylate) have no effect on the marginal integrity of restorations; (2) A layer of bulk-fill resin compo-site liner of the same category would not affect the marginal or internal adaptation of restorations.

Dental caries is one of the most prevalent chronic diseases in people worldwide. Traditional clinical treatment of dental decay has developed on the basis of the removal of carious tissues with high-speed handpieces and slow-rotating instruments, inducing pain, disturbing sounds, and vibrations. In addition, this method comprises the tooth structure by removing both "caries-affected dentin" and "caries-infected dentin". The use of the chemo-mechanical caries removal (CMCR) method is one of the main implementations of the minimal intervention dentistry idea accepted in the last ten years. It includes the selective removal of "caries-infected dentin" while preserving the healthy "caries-affected dentin" that has the ability to remineralize. The CMCR method differs from the traditional surgical method in that it selectively removes carious dentin. Therefore, it is less destructive and less painful, thereby promoting a positive attitude towards visiting dentists. A novel agent for the CMCR method named "BRIX3000®" by the laboratory Brix Medical Science has been released onto the dental market in 2016. It is a papain-based gel derived from latex and fruits of green papaya (Carica Papaya) that works as a chemical debridement with a unique technology called Encapsulating Buffer Emulsion (EPE). Investigations are required to evaluate and compare the outcomes of two CMCR agents, "BRIX3000®" and "Carie-CareTM," versus the traditional surgical methods. Therefore, the present study aims to perform a clinical and microbiological evaluation of caries removal using "BRIX3000®" and "Carie-CareTM" versus the traditional surgical methods in primary molars among children in Jeddah city, Saudi Arabia.
