Active clinical trials for "Stomatognathic Diseases"

The aim of this study was to evaluate the clinical performances of Edelweiss prefabricated veneers and direct resin composite restorations (Ceram-X Duo SphereTec) performed with U- veneer transparent templates used for anterior diastema closure and tooth reshaping over 3-year. The patient group consisted of individuals who applied for aesthetic complaints on their anterior teeth. 21 volunteer individuals without systemic disease were included in the study. Patients were randomly selected for each group. In Group 1; 38 teeth (10 patients) were restored with Edelweiss prefabricated veneers (Edelweiss Dentistry) in combination with Edelweiss nanohybrid resin composite (Edelweiss Dentistry) and Prime&Bond Universal (Dentsply Sirona) adhesive system. In Group 2; 36 teeth (11 patients) were restored with Ceram-X Duo SphereTec (Dentsply Sirona) resin composite in combination with U- veneer (Ultradent) transparent templates and Prime&Bond Universal adhesive systems. Properties of the restorations were evaluated at baseline, 6, 12, 24, and 36 months using Modified Ryge Criteria (USPHS Criteria). Data were evaluated using Chi-Square and Fisher's Exact tests (p=0.05).

Restoration of endodontically treated teeth requires a means to protect the cusps from the wedging forces of occlusion. When there is extensive loss of tooth structure, cuspal coverage is warranted. Usually this is in the form of indirect restoration. Traditionally, full coverage crowns have been used which would require further removal of sound tooth structure. Recently, adhesive alternatives have been introduced which allow for conservation of tooth structure. Different materials can be used for this purpose. The evidence on the long-term survival of these materials is scarce. This study aims to investigate the short and medium-long term survival rate of these prostheses.

The aim of this study is to compare the clinical performance of composite veneers performed in two different ways, indirect and direct methods over a period of 6-year. 30 volunteer patients without systemic diseases and who applied to Ege University School of Dentistry for the esthetic restoration of their anterior diastema (gap) were selected according to inclusion and exclusion criteria. The closure of 102 diastema was randomly performed with prefabricated composite resin veneers (n=15; indirect method- Componeer, Coltène, Altstätten, Switzerland) or direct composite resin veneers (n=15; direct method- Essentia, GC, Japan). These restorations were clinically evaluated at baseline, 1-2-6-year by two experienced and blind examiners according to modified Ryge criteria (USPHS criteria). Color match, marginal discoloration, anatomic form, marginal adaptation, secondary caries, surface roughness, retention, and polishing retention were evaluated for that purpose. Statistical analysis was performed with McNemar and Chi-square tests (p<0.05).

The current study (ORARAD II) will examine participants of the original cohort for a visit roughly 7 years after the start of RT. The primary outcomes will be the 7-year rate of dental caries, periodontal disease, tooth loss, osteoradionecrosis and salivary flow.

The purpose of this study is to measure the two-year rate of tooth loss in patients who have received external beam radiation therapy with curative intent for head and neck cancer. The study will also evaluate the sequelae of radiation therapy and oral complications that may occur as a result to receiving radiation therapy.

Oral health problems in school children are highly prevalent in Nepal. The investigators designed oral health counseling and promotion intervention in Kaski district of Nepal for six months. The study was conducted intervention covering dental check up, counseling, supporting with brush materials, toothpaste, and essentials. The investigators also trained school teachers to provide oral health education in school children and completed the endline data collection to assess the effect of intervention.

The goal of this project is to analyze the effectiveness of calculus and biofilm removal using area-specific hand scalers such as Mini Five® Gracey Curettes and Micro Mini Five® Gracey Curettes in periodontal pockets that are 5mm or greater. The data collected from this project will provide the evidence needed to support the use of modified hand scalers during non-surgical periodontal therapy for clinicians.

The purpose of this study is to evaluate the effectiveness of a preventive strategy in increasing return to follow up and recall appointments.

Investigation of bacterial adhesion and bactericide effect ex vivo on different implant restoration materials

Current radiologic imaging modalities used in dentistry provide information on the morphology of the hard tissues. Additional information on the density of bone has practical relevance, for example, in dental implant treatment planning, where local bone quality is a known strong predictor of successful implant osseointegration. The Dual-Energy Cone Beam Computed Tomography (DE-CBCT) device is designed to overcome limitations of traditional imaging and will provide assessment of jaw bone density in additional to morphological information. This clinical trial will examine the application of DE-CBCT to assess jaw bone density and compare Hounsfield units (HU) values with multidetector CT, an established standard for assessing BD.
