Active clinical trials for "Dental Caries"

Matching the color of resin composite utilized in anterior teeth is believed to be one of the most challenging tasks a dentist has to face in daily practice. The color of the teeth is primary influenced by dentin; on the other hand, enamel has a major influence on the color perception in terms of lightness. In the layering concept, the missing dental tissues are substituted in increments with resin composite of the exact shade as the dental tissue. A translucent composite resin is applied over a more opaque composite resin to achieve a depth perception similar to that of the natural teeth. Which indicates that the visible color is the consequence of diffuse reflectance from the internal dentin or opaque material layer through the external translucent layer. There are numerous elements that make the color matching problematic. These problems arise from the point that color matching rely on many different chromatic properties related to the teeth and resin composite; those include hue, chroma and value; translucency, opalescence and fluorescence; light diffusion and transmission; and luster and texture of the surface. To reach the ideal esthetics, restorative material should mimic the natural tooth in the previously mentioned properties, in addition of having a long time color stability. Massive efforts were achieved over the years to improve the esthetic properties of dental resin composite restorative materials. Recently, a single shade structurally colored universal composite (Omnichroma, Tokuyama Dental) intended for use with most direct restorative clinical cases was introduced in the market. Its manufacturer claimed that it exhibits color change toward the color of the surrounding hard dental tissues. Thus, it has the advantages of improving the esthetic appearance of the restoration, decrease dependence on shade-matching procedures, decrease the number of shade guide tabs, and counteract for color mismatches to some degree. Up till now no studies assessed the color match of Omnichroma resin composite in anterior teeth cavities clinically. Thus, the aim of this clinical trial was to investigate if the single shade structurally colored universal resin composite (OMNICHROMA) will modify its shade to match the tooth structure shade in anterior teeth cavities.

Aimed to be done in the planned thesis to evaluate the dental and periodontal health of patients with newly diagnosed JIA and healthy-periodontal problems with cytokines from saliva and oxidative stress markers non-invasively, and thus, to determine the markers' evaluability in terms of markers in determining the state of inflammation among individuals with and without the disease.

Vital pulp therapy (VPT) is a general term for multiple procedures (indirect pulp cap, direct pulp cap and pulpotomy) all directed toward preserving pulp vitality and enable complete root development in immature teeth. The aim of this study is to evaluate the clinical, radiographic and histologic (if any teeth later are doomed for extraction for orthodontic or other reasons) success rate of VPT on treating cariously exposed permanent teeth with developmental defects of enamel. This will be a a prospective case series study including children between 6-16 years old having tooth with enamel hypomineralization defect with deep caries, restorable teeth , and no signs of infection. The teeth will be followed up both clinically and radiographically for 1 year after treatment. It is expected that the teeth will maintain vitality with resolution of symptoms (if present) and completion of root development in immature teeth after vital pulp therapy.

A cohort of newborns was recruited for the Iowa Fluoride Study from 1992-95 to assess the complex relationships among fluoride intakes, fluoride exposures, dental fluorosis, and dental caries. Detailed questionnaires were sent every 1.5-6 months concerning water sources, fluoride exposures, dietary intakes, etc. Standardized dental exams were conducted at ~ages 5, 9, 13, 17, and 23. At about age 5, participants were invited to join the offshoot Iowa Bone Development Study. Bone densitometry assessments were conducted at ages 5, 8, 11, 13, 15, 17, 19, and 23. These included Dual-energy X-ray Absorptiometry (DXA) of hip, lumbar spine, and whole body from age 5; peripheral Quantitative Computed Tomography (pQCT) of the radius and tibia from age 11; and Multi-Detector Computed Tomography (MDCT) of the tibia from age 19. Physical activity and other factors also were assessed longitudinally.

This is a RCT that will compare the clinical and radiographic success of pulpotomies on primary molars between the traditional technique (Formocresol/ZOE) and the new technique with Biodentine. 180 pulpotomies (90 in each group) will be followed for a period of 12 months.

AIM: To evaluate influence of two methods to avoid saliva contamination on the survival rate of atraumatic restorations in primary molars. 232 children, aged between 6-7 years, of both genders, were selected having one primary molar with a proximal dentine lesion. The children were randomly divided into two groups: a control group with class II ART restoration made using cotton rolls and an experimental group using rubber dam. The restorations were made and they were followed up every six months. After two years, the results were compilated and analyzed.

The purpose of this study is to evaluate the therapeutic benefit of Curodont Repair for the treatment of early approximal carious lesions compared to no treatment.

This study assessed the clinical performance of a resin-modified glass ionomer cement containing different concentrations of chlorhexidine digluconate and doxycycline hyclate.

This study aimed to evaluate the clinical performance of a novel vitro-ceramic biomaterial (Biosilicate®) as treatment of caries-affected dentin in posterior resin restorations. A total of 94 restorations of 66 participants were selected and assigned at random into four groups: 1 (Biosilicate / Two-step etch and rinse system), 2 (Control / Two-step etch and rinse system), 3 (Biosilicate / Two-step self-etching system) and 4 (Control / Two-step self-etching system). Two operators carried out the adhesive protocols and restored the cavities with a nano-hybrid resin composite (IPS Empress, Ivoclar) using the incremental technique. Participants were recalled at one week, 6, 12 and 18 months for clinical evaluation performed by two blinders and calibrated examiners according FDI criteria.

The purpose of this study is to compare esthetic, functional and biological properties of two restoration materials used to fill cavities. One material is called "Filtek™ Supreme" which is a traditional tooth colored resin composite that is placed in the cavity in layers and hardened with UV light. The second material is called "SonicFill™ 2," which is a bulk fill composite that uses an ultrasonic hand piece to change the material from a solid into a liquid in order to place it into the cavity. This material can be placed in the cavity in 1 layer, and is hardened using UV light. Both materials have been FDA approved as non-significant risk devices for filling cavities. In each subject, one tooth with a cavity will be randomly selected to receive one filling material, and a second tooth with a cavity will be randomly selected to receive the second material. The fillings will be observed over a two year period to determine clinical acceptability.
