14 Clinical Trials for Various Conditions
This study focuses on assessing dental caries, erosive tooth wear, and fluorosis in primary teeth using a 3D intraoral digital scanner. The investigator will validate findings using three key indices: ICDAS (for caries), BEWE (for erosive wear), and TF (for fluorosis). Teeth will be cleaned and examined visually using dental tools and light. After visual checks, teeth will be scanned with a 3D intraoral scanner. Children aged 3-12 years with fully erupted primary teeth, seeking dental treatment at the Department of Pediatric Dentistry, Indiana University School of Dentistry. The visual examination and digital scanning will be performed just once and during the dental appointment at the clinic of Pediatric Dentistry following the protocols used in the clinical routine. It is expected to complete the visual examination and the digital scanning in 30 minutes.
This randomized clinical trial evaluates the clinical performance of a new two-component self-etch universal adhesive, OptiBond XTR, when applied in non-carious Class V cervical lesions without macromechanical retention (retentive grooves or bevels). The control material is OptiBond FL, a "traditional" etch/prime/bond adhesive with documented clinical performance. Eighty non-carious Class V cervical lesions are divided into two groups to be treated with either OptiBond XTR or OptiBond FL. Both adhesives are applied strictly according to the manufacturer's directions. Herculite Ultra, a nano-hybrid resin-based composite, is used as the restorative material with both adhesives. The restorations will be evaluated at insertion (baseline), 6 months, and 18 months. An optional three-year recall evaluation is also proposed. The investigators hypothesize that both adhesives will have comparable performance.
This study investigates how often cavities develop on the permanent teeth of patients with braces (orthodontic treatment). The hypothesis is that there is no difference in the number of cavities on the permanent teeth of patients with braces compared to similar patients without braces.
This trial is a Phase III, multisite, randomized, placebo-controlled trial, with two parallel groups. The groups are SDF or placebo and they are applied every 6 months. The primary hypothesis of the trial is that SDF is better than placebo for stopping cavities with dentin exposed in baby teeth when assessed at 6 months after initial application.
The purpose of the study is to determine if Clinpro™ 5000, Clinpro™ Tooth Crème, or MI-Paste Plus has an effect on the formation and resolution of white spot lesions for patients undergoing orthodontic treatment. This study will include 90 patients in the UAB Orthodontic Clinic.
The purpose of this study is to determine whether a new tooth-colored composite material is effective for load-bearing dental fillings.
This is a three year single site clinical evaluation of a FDA approved (510(k):K100062) lesion penetrating resin used to infiltrate and hamper progression of proximal carious lesions. The purpose of this study is to compare lesion progression infiltrated with (Icon, Hamburg, Germany) to a similar sized lesion in the same patient treated with a placebo. The study is designed as a randomized, controlled, prospective clinical trial with a three year follow-up evaluation period. The clinical site will enroll 150 subjects (in the age range of 19 years or older) with 2 study lesions. The patients will be evaluated at six time points over a period of 3 years. Lesion status and caries risk will be monitored at 6-month intervals, while radiographic evaluation will be conducted at 12-month intervals at 1-, 2- and 3-year recall visits.
The purpose of this study is to determine whether lesion infiltration is an effective management strategy to arrest early tooth decay.
This study is investigating the efficacy of caries lesion infiltration therapy as compared to the current preventative approach for early caries lesions.
Study hypothesis: a new, low polymerization stress flowable composite performs no differently to a conventional, highly filled composite filling material when used as a restorative in small cavities in back teeth. Study will evaluate the clinical performance of a low shrinking flowable composite filling material, compared with a conventional, highly filled composite restorative when used to permanently fill small cavities in molar and premolar teeth in adult patients.
The purpose of this study is to learn more about the management of white spot lesions that occur after orthodontic treatment. White spot lesions generally improve slightly with time. To date, there is no proven method to help white spot lesions improve faster. Two treatments, called MI Paste Plus and fluoride varnish, have shown some potential benefits in a laboratory setting but have not undergone testing in a clinical setting. Approximately 240 subjects are to be enrolled in this study. The study will take place in approximately 30 dental and orthodontic offices across Idaho, Montana, Oregon, Utah, and Washington as part of Northwest PRECEDENT, a five-state research network that was created to study the practical issues facing dentists/orthodontists and their patients, and to provide information that will improve the quality of oral health care as a whole. Researchers at the University of Washington and Oregon Health \& Science University share management and oversight of the network and research projects.
The overall objective of this three-armed randomized clinical trial (RCT) is to determine the comparative efficacy of three treatments for hypersensitive noncarious cervical lesions (NCLs): chemoactive dentifrice use, dentin bonding agent (DBA) with sealing, and flowable resin-based composite restoration. The primary outcomes of this study are the reduction/elimination of hypersensitivity and the effect of treatment as measured by patient-reported outcomes. Secondary outcomes, as determined by laboratory evaluation of intraoral replicas of pre- and posttreatment NCL surfaces, are tubule occlusion, retention of resin coating, retention of restoration, and change in lesion size. Outcomes will be ascertained via the following specific aims: Specific Aim 1: To compare the reduction of hypersensitivity of study teeth by both measurement and by patient-reported outcomes among three treatment groups. Specific Aim 2: To recruit subjects with teeth with hypersensitive NCLs, measure baseline sensitivity and subject quality of life, administer one of three different treatments to each of three randomized groups of subjects, and determine immediate posttreatment hypersensitivity. Specific Aim 3: To compare the degree of tubule occlusion before and after the three treatments and to associate these findings with posttreatment hypersensitivity, patient-reported outcomes, and restoration retention. Treatment of NCLs remains controversial. Few studies have compared treatment methods or their financial implications. This RCT will determine the reduction of NCL hypersensitivity and patient-reported outcomes over a 6-month period for each of three different treatments. This will be the first practice-based research network RCT to combine objective clinical assessment of NCL treatment patient-reported outcomes with laboratory examination of dentin tubule occlusion and lesion size.
The purpose of this study is to determine whether two tooth-colored glass ionomer materials are effective for load-bearing dental fillings.
The purpose of this study is to extend our knowledge concerning the clinical performance of two dental filling materials in molars. The study will compare two high-strength glass-ionomer filling materials. The investigators hypothesize that after two years (1) the clinical performance of both filling materials shows a similar survival rate, (2) the ChemFil Rock fillings show similar or higher incidence of fracture than Fuji IX GP fillings.
