Class IIClass IIMaterial: TPH and ProBondTitle: A Two-year Clinical Evaluation of

TPH/Variglass VLC for restoration of Class II Carious Lesions in Permanent Teeth.

Principle Investigators: Dr. Gerard Kugel, Dr. Ronald Perry, and Dr. Charles Habib

Type of Restorations: Class II2 Year results: 28 Patients; 29 Restorations; (% alpha—highest

rating): Retention (100%), Sensitivity (100%), Color Stability (100%), Marginal Leakage (100%), Marginal Integrity (97%), Secondary Caries (100%), Surface texture (100%), Proximal Contact (100%).

Average Wear Values: 1-yr. (0 to 24µm, n=24; 25 to 49µm, n=6, 50 to 74µm, n=2), 2-yr (0 to 24µm, n=18; 25 to 49µm, n=5, 50 to 74µm, n=2, >75µm, n=1)

Summary: Analysis for wear over the 2-year period resulted in an average of 10.3 m. No post-operative sensitivity was observed. Excellent clinical performance was observed in the study, with all restorations being clinically acceptable. TPH restorations showed satisfactory values in all categories, demonstrating clinical efficacy as a restoration material over the period of the study.

a Posterior and Anterior Composite Restorative Material

Principle Investigators: Drs. Makoto Suzuki and Donald F. Davidson

Type of Restorations: Class I, II & IV4-year Results: 26 Patients, 78 restorations (63 Class I & II; 15 Class

IV); (% alpha—highest rating): Retention (100%), Anatomical Form (100%), Sensitivity (100%), Color Match (100%), Marginal Integrity (67%), Marginal Discoloration (89%),Secondary Caries (97%), Occlusal Wear (89%), Surface texture (89%), Axial Contour (100%) Fracture Resistance (100%).

Average Wear Values: 4-yr. (10 to 19µm, n=1; 20 to 29µm, n=0; 30 to 39µm, n=15; 40 to 49µm, n=29; 50 to 59µm, n=16; 60 to 69µm, n=2). Average general occlusal wear from baseline was found to be 43 m.

Summary: Excellent color stability, maintenance of anatomical form and interproximal contact has been invariably observed. There were no bulk fractures or dislodgment of the restorations. Based on 4 year recalls, TPH performed exceptionally well clinically and the average occlusal wear was well within that allowed by the ADA relative to composite resin restoratives on posterior dentition.
