Ecological Effect of Arginine Dentifrice on Oral Microbiota

Dental CariesOral Bacterial Infection1 more

caries-free (CF) individuals caries-active (CA) individuals (DMFT ≥ 6) will be recruited. Subjects will be instructed to brush their teeth twice daily for 3 min using Colgate® Sensitive Pro-Relief® toothpaste (containing 8% arginine and 1450 ppm NaF) for 2 weeks. Supra- and subgingival plaque, saliva, and in situ plaque samples will be collected before and after the treatment for laboratory analyses.

A Clinical Assessment of Glass Carbomer Cement

Dental Caries Class II

This study will evaluate the clinical performance of glass carbomer cement restorations in restoring proximal lesions in primary molars compared to that of resin modified glass ionomer cement and composite resin restorations. Teeth will be randomly assigned to one of the three restoration groups and the restorations will be evaluated clinically and radiographically every six months.

Intraoral Imaging at Clinical Crown Lengthening

Dental Caries of Root SurfaceSurgery

Crown lengthening surgery is done when a tooth needs to be fixed with a crown. Sometimes, not enough of the tooth sticks out above the gum to support a crown. This can happen when a tooth breaks off at the gum line, or when a crown or filling falls out of a tooth and there is decay underneath. To place a crown, the dentist needs to expose more of the tooth. This is done by removing some gum tissue or bone. After surgery, the area will heal in about three months. Then, making a crown can begin. This healing period often delays the delivery a final crown. This study is investing a way to make the final impression at the surgery to expedite the delivery of a final crown.

Clinical Performance of a Glass-ionomer Restorative System: A 6-year Evaluation

Dental Caries

The aim of this clinical trial was to compare the clinical performances of a glass ionomer restorative system with a micro hybrid resin based composite in class I and class II cavities. A total of 140 (80 class I and 60 class II) lesions in 59 patients were restored with a glass ionomer restorative system (Equia) or a micro hybrid composite(Gradia Direct). Restorations were evaluated at baseline and yearly during 6 years according to the modified-USPHS criteria. Data were analyzed with Cohcran's Q and McNemar's tests (p<0.05).

Clinical Performance Evaluation of a Glass-ionomer Restorative System Evaluation

Dental Caries

The aim of this clinical trial was to compare the clinical performances of a glass ionomer restorative system with a micro hybrid resin based composite in class I and class II cavities. A total of 140 (80 class I and 60 class II) lesions in 59 patients were restored with a glass ionomer restorative system (Equia) or a micro hybrid composite(Gradia Direct). Restorations were evaluated at baseline and yearly during 9 years according to the modified-USPHS criteria. Data were analyzed with Cohcran's Q and McNemar's tests (p<0.05).

The Proximal Contact Tightness and Location in Class II Composite Restorations

Tooth Decay

This study aims to investigate consecutive biological changes in proximal contact tightness using digital force gauge and evaluate proximal contact location using cone beam computed tomography between class II direct composite restorations and adjacent teeth after using sectional matrix system and with different contact forming instruments.

Clinical Performance of Composite Coronal Build -Up in Mutilated Primary Incisors: 3 Years Results...

Early Childhood CariesPediatric Disease2 more

Prospective single arm study was to evaluate the clinical success and/ or failure of resin-bonded composite coronal build-up retained by macro-retentive grooves for restoring mutilated primary maxillary incisors after 36 months. Design: Forty two primary incisors out of 14 children, aged 2-5years, treated in a private pediatric dental practice under general anesthesia and presented for follow-up after 6, 12, 18, 24 and 36 months included in the study. The parameters recorded at the baseline and at the follow-up intervals were: retention, colour match, the number and location of the decayed surfaces (recurrent caries), chipping /fracture of the restoration and loss of restoration (failure). Materials and Methods: A total of (14) pediatric patients aged from 2-5 years presented with mutilated primary anterior teeth due to caries or trauma and treated comprehensively under general anesthesia from June 2016 to June 2017 were enrolled in this study. A total of (42) decayed or traumatized primary anterior teeth were treated with composite coronal build-up based on the micro-mechanical adhesive procedure of composite resin in addition to macro mechanical retentive grooves created on the lateral sides of the cervical one third of the roots of treated teeth. The patients returned at the end of 6, 12, 18, 24 and 36 months and received clinical examinations. Another dentist (co-author) who did not attend the treatment evaluated the strip crowns clinically by modified United States Public Health Service (USPHS) criteria.

Clinical Evaluation of Extensive Direct Composite Restorations With Polyethylene Fiber

Dental Caries Extending Into Dentin

The aim of this clinical trial was to compare the clinical performances of composite resin restorations with/without the polyethylene fiber to the first permanent molar teeth with extensively carious pediatric patients. A total of 75 restorations with (FC; n=38)or without (C; n=37) fiber were placed in the first permanent molar teeth. Restorations were evaluated at baseline-6-12-18 months according to the modified-USPHS criteria. Data were analyzed with Chi-Square and Cochran's Q (p<0.05).
