Active clinical trials for "Dental Caries"

Specific Aims To determine the diagnostic efficacy of CariVu and BWX for detecting interproximal carious lesions in primary dentition BWX and CariVu images will be taken in random order. Number and depth of interproximal carious lesions will be determined by two independent examiners using both CariVu images and BWX. Intra- and inter-rater agreement and disagreement will be determined for all the images and radiographs. To determine acceptability and comfort of CariVu and BWX as perceived by patient, parent and independent observer BWX and CariVu images will be taken in a random order and patient and parent will be given a questionnaire to complete as exit survey. The questionnaire will include few questions to determine perceived acceptability and comfort by parent and patient for either methods (CariVu and BWX). An independent observer (dental assistant) who is masked for the hypothesis of the study will be given a similar questionnaire to evaluate patient behavior using standard behavior assessment scales. To determine difference in chair-side time required for BWX and CariVu image generation Time required to generate both, BWX and CariVu images will be documented by an independent observer (dental assistant) who is masked for the hypothesis of the study and will be compared to determine the overall clinical chair-side time required for generating diagnostic images for efficient and accurate treatment planning

Prevention of oral diseases is preferable to treatment and is the key method of achieving cost effectiveness for oral health improvement programs. Various preventive strategies for dental caries have been tried and are still being developed. The occlusal pits and fissures of posterior teeth are highly susceptible to caries because of the anatomy of pit and fissure surfaces, which favours stagnation of bacteria and substrates. Fissure sealing has been shown to be an evidence-based caries preventive method for protecting the occlusal surfaces against caries. Non- sealed teeth need to be restored approximately 50% more frequently compared to their sealed counterpart. Sealants are effective caries preventive agents as long as they remain bonded to teeth. It has been proposed that sealants should be placed on both sound teeth and incipient non-cavitated carious lesions on permanent teeth of high caries risk patients in order to prevent the onset of caries and its progression. According to the American Dental Association Guidelines for the use of pit and fissure sealants, ICDAS II codes 0, 1 and 2 are recommended for sealant application.A variety of dental materials have been used as sealants using different application techniques. Their effectiveness depends on the formation of a complete seal and is increased by correct technique and moisture control, appropriate follow-up and resealing as necessary. Resin-based conventional sealants are preferred choice, however use of phosphoric acid demineralizes the enamel layer and have elongated treatment time and is more technique sensitive.

Background: The Hall Technique (HT) is a non-invasive, easily applicable minimally invasive dentistry approach for managing dental caries in children. It involves placing a preformed metal crown over a tooth with decay, to seal it in and stop the decay from progressing. However, it alters the occlusion as no tooth substance is removed to make space for the crown. Objective: This study, aims to evaluate the effects of Hall Technique on occlusion in children, to assess whether there are any adverse effects on the temporomandibular joint and masseter muscles, related to changes on occlusion and to evaluate the children's perceptions of the crowns. Materials and Methods: A total of 37 children aged 5-9 years, who have not been treated with the Hall Technique previously and who have dentinal caries that did not reach the pulp (affecting the occlusal or the occluso-proximal surfaces) in their primary molars, will be invited to participate in the study. At the first visit, clinical examination will be carried out and intraoral impressions will be taken for pre-treatment evaluation. The occlusal vertical dimension of the teeth will be measured clinically with callipers. Temporomandibular joint and masseter muscles will be examined clinically. Then, the Hall Technique crown will be placed to treat the carious tooth, the impressions taken again, and measurements repeated. At one and three months following treatment with the crown, the participant will have the measurements repeated. The child and parent will complete a questionnaire after 3 months on their perception of the crown. In the data analysis, frequency, percentage, mean and standard deviation analyses will be used for demographic data and description of the clinical data. In numerical data analysis, t-test or Mann-Whitney U test will be used according to the data distribution. Geomagic software will be used to analyse sequential study models of the teeth to measure relative changes in the tooth positions over time.

The aim of the clinical trial is to assess pain during Atraumatic Restorative Treatment (ART), Smart Burs and Chemo-mechanical Caries Removal (CMCR) in primary molars.

Isolation is essential for the successful placement of esthetic restoration to avoid any contamination of cavity with saliva ,secreation,and blood dental . This study is comparison of optradam and convetional rubberdam system.The aim of this study is to investigate which rubberdam system is better accepted by patients and dentists

To compare the effectiveness of the semi-annual application of 38% SDF with two post-treatment protocols in arresting dental caries in preschool children

The primary purpose of this study is to determine the local anesthetic efficacy and safety of 4% Articaine compared 2% Mepivicaine in 3 years old children, by using infiltration technique for primary teeth that required restorative, pulp therapy, or dental extraction procedure, as assessed by measuring the pain experience during injection and treatment procedures, child's behavior during the procedure, and postoperative complications.

This study will compare between S-PRG-containing injectable flowable resin composite (Beautifil Flow Plus X) and smart bioactive flowable resin composite (Activa bioactive restorative) through evaluation of the modified USPHS clinical performance in patients with carious class V moderately deep cavities.

This study aimed to evaluate the oral health related quality of life ( OHRQoL), during caries management in children with vital carious primary teeth with no signs of irreversible pulpitis using SDF alone or SDF in combination with ART, using Early Childhood Oral Health Impact Scale (ECOHIS).

Occlusal caries management in first permanent molars: a pragmatic randomized clinical trial in child dental care Aim of the present study is to evaluate the effectiveness of fissure sealants and fluoride varnish in a pragmatic randomized clinical trial and evaluate whether some specific patient groups benefit more from any particular treatment. The high risk children (having a previous caries experience at 5 years of age) from 2009, 2010 and 2011 birth cohorts (6-, 7- and 8-year-olds) from three counties (Østfold, Oppland and Hedmark) are selected. Children with at least two erupted first permanent molars in the same jaw randomly receive resin-based sealant or a fluoride varnish (Duraphat) during a routine dental examination. Children who already developed caries, had restorations or fissure sealants placed in first molars were excluded from the present study. Fluoride varnish and resin-based fissure sealants are randomly applied on contra-lateral teeth where each child serves as its own control. This study uses a natural clinical setting, where clinicians use methods and procedures that are routinely applied in public dental clinics. The study is approved by the Regional Committee for Medical Research Ethics South East (2016/2002/REK sør-øst C). Sample size calculations: Based on the assumption that 80% of the treated teeth do not get caries and that 10% difference in caries development constitutes a clinically meaningful difference, it is required to recruit 180 participants in the study for the split-mouth design. Considering a potential maximum of annual 20% drop-out rate and a 3-years follow-up, the study will need to recruit 400 participants in order to have at least 206 children at the 3 years of follow-up. Treatments are provided by either dentists or dental hygienists during routine dental examinations. Caregivers of eligible children are informed about the study, the participation is voluntary and an informed written parental consent is obtained in accordance with the directions of the Regional Committee for Medical Research Ethics. In this study, a clinician selects a random treatment for the first tooth by choosing one of the two cards, while a collateral tooth receives an alternative treatment. Subsequently, treatments provided and materials used are recorded on a treatment registration form. During this study, clinicians follow their conventional clinical procedures for applying sealants or fluoride varnish. Information on patient's caries experience and quality of oral hygiene are recorded on treatment registration form. Fluoride varnish is applied three times, at baseline, 6 months and 12 months. Caries on occlusal surfaces of first molars detected at later 24 and 36 months follow-ups will be recorded in the follow-up registration form. The main study outcome is caries occurrence on occlusal tooth surfaces.
