Bleaching of nonvital teeth. A clinically relevant literature review.

Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia, 2010
Today, the bleaching of nonvital, discolored teeth is a low-risk routine treatment for improving esthetics. This review article focuses on the etiology of tooth discolorations, different treatment techniques, and risks of bleaching procedures. Some tooth discolorations in endodontically treated teeth are caused by dental treatments.

Touch thresholds of vital and nonvital human teeth

Experimental Neurology, 1975
Abstract Stewart (5) determined the touch thresholds of incisors in human subjects and found that the thresholds of the few pulpless teeth he examined did not differ significantly from those of the vital teeth. On the other hand, Loewenstein and Rathkamp (3) found that the thresholds for pulpless teeth were 57% higher than those of vital teeth, and ...

Bacterial invasion into dentinal tubules of human vital and nonvital teeth

Journal of Endodontics, 1995
The difference in resistance to bacterial invasion into the dentinal tubules between vital and nonvital teeth has not been determined. This study was conducted to clarify the effect of vital pulp on bacterial invasion into the dentinal tubules. The specimens were 19 intact pairs of bilateral upper third molars of 19 healthy, young adult male volunteers.

Composite Resin Interim Restorations for Broken-Down Nonvital Posterior Teeth

Journal of the American Dental Association, 1983
The fabrication of interim restorations using a retentive groove preparation design with a custom composite resin core material has been used in my private practice for more than ten years with gratifying results. In the past 2 1/2 years, more than 800 such restorations have been documented and placed at the University of Southern California School of ...

Apical closure of nonvital teeth

Oral Surgery, Oral Medicine, Oral Pathology, 1971
Abstract A study was undertaken to demonstrate the apical development that occurs following debridement and filling of the root canal with a calcium hydroxide—camphorated parachlorophenol paste. Microscopic sections indicated that treatment of the teeth had stimulated the formation of granulation tissue to repair the bone destruction and soft-tissue ...

Retention of posts in teeth with nonvital pulps

The Journal of Prosthetic Dentistry, 1983
The results of this study indicate that: 1. Cast posts without grooves are more retentive when cemented with zinc phosphate than with composite resin. 2. Cast posts with grooves in the posts and adjacent grooves in the teeth are more retentive than cast posts without grooves. 3.
