Clinical Survival of Indirect, Posterior Fiber-Reinforced Composite Fixed Dental Prosthesis: Up to 15 Years of Prospective Clinical Follow Up.

This prospective clinical study evaluated the survival of indirect, posterior fiber-reinforced composite fixed dental prosthesis (FRC FDP). Between June-1999 and June- 2000, 58 patients received 65 FCR FDPs made of unidirectional E-glass fibers (Vectris) veneered with resin composite (Signum) that were adhesively cemented (Variolink II). The evaluation protocol involved technical (chipping, debonding or fracture of tooth/restoration) and biological failures (caries, endodontic complications).

Clinical Performance of Posterior Microhybrid Resin Composite Restorations Applied Using Regular and High-Power Mode Polymerization Protocols According to USPHS and SQUACE Criteria: 10-Year Randomized Controlled Split-Mouth Trial.

Purpose: This randomized, split-mouth clinical study evaluated the marginal quality of direct class-I and class-II restorations made of microhybrid composite that were applied using two polymerization protocols and two marginal evaluation criteria.

Materials And Methods: A total of 50 patients (mean age: 33 years) received 100 direct class-I or class-II restorations in premolars or molars. Three calibrated operators made the restorations.

Rotary versus reciprocating shaping files in bacterial elimination from long oval canals.

A comparison of the abilities of rotary versus reciprocating files to eliminate viable Enterococcus faecalis populations from the long oval root canals of extracted human teeth. Fifty teeth were contaminated and randomly distributed into two groups (n = 25 each): BT-RaCe group and WaveOne group. Two microbial samples were obtained from each tooth before (S1) and after (S2) instrumentation.

Microbiological characterization and effect of resin composites in cervical lesions.

Background: Non carious cervical lesions associated to muscle hyperfunctions are increasing. Microhybrid resin composites are used to restore cervical abfractions. The purpose of this study was to investigate if resin composites modify tooth plaque, inducing an increment of cariogenic microflora and evaluate their effect, and , against .

Comparative analysis of SAF, Protaper Next and BT-Race in eliminating Enterococcus faecalis from long oval canals: An ex vivo study.

Comparison of the ability of newly designed rotary files to eliminate viable Enterococcus faecalis populations from long oval root canals of extracted human teeth to that of the self-adjusting file (SAF). One hundred caries-free, single-rooted, long oval teeth were contaminated with E. faecalis.
