Pulp capping: influence of the exposure site on pulp healing-histologic and radiographic study in dogs' pulp

Journal of Endodontics, 1981
Pulps of dogs' teeth were exposed buccally and occlusally and capped with calcium hydroxide powder. On the 22nd and 120th postoperative days the teeth were examined histologically and radiographically. Calcium hydroxide powder stimulated pulp healing and calcified bridge formation as early as 22 days for both exposure groups.

Experimental exposure of hamster pulp

Oral Surgery, Oral Medicine, Oral Pathology, 1956
Abstract A method of pulp exposure and treatment has been described, using hamsters to overcome some of the difficulties and objections met with in this type of experiment. The results have been evaluated histologically, and the findings compared with those of others who used larger-animal and human subjects.

Controlling In Vivo, Human Pulp Temperature Rise Caused by LED Curing Light Exposure.

Operative dentistry, 2019
OBJECTIVE The objective of this study was to evaluate the in vivo effectiveness of air spray to reduce pulp temperature rise during exposure of intact premolars to light emitted by a high-power LED light-curing unit (LCU).

Influence of Class V preparation on in vivo temperature rise in anesthetized human pulp during exposure to a Polywave® LED light curing unit.

Dental Materials, 2018
OBJECTIVE This in vivo study evaluated pulp temperature (PT) rise in human premolars having deep Class V preparations during exposure to a light curing unit (LCU) using selected exposure modes (EMs).

The effect of blood clotting on hamster pulp exposures

Oral Surgery, Oral Medicine, Oral Pathology, 1957
Abstract Under conditions and with methods previously described, blood clot alone did not give satisfactory results in the treatment of the cut surface of the pulp. Instead, the histologic evidence indicated severe degenerative changes. The function of “inert” capping material is discussed.

Pulpal response to different pulp capping methods after pulp exposure by air abrasion

Journal of Clinical Pediatric Dentistry, 2002
Air abrasion is regaining popularity especially in the area of pediatric dentistry due to its ease of use and its advantages. Due to the lost of tactile information, while using this technique, there is an increased risk for pulpal exposure. On the other hand, Ca(OH)2 medicament has been proven to induce dentin bridge formation, but an adequate sealing

Bacterial contamination as a factor in healing of pulp exposures

Oral Surgery, Oral Medicine, Oral Pathology, 1974
Abstract An in vivo technique is introduced that uses a rat model with caries produced by Streptococcus mutans on the tooth surface available to a standardized procedure for cavity preparation and restoration. Pulps exposed during removal of caries with this technique were more likely to be iatrogenically infected by the implantation of bacteria ...

Job—Exposure Matrices and Retrospective Exposure Assessment in the Pulp and Paper Industry

Applied Occupational and Environmental Hygiene, 1998
Abstract For the purpose of performing a case—control study, the information regarding the exposures of 30,000 pulp and paper workers was organized into 90 job-exposure matrices. Semiquantitative exposure estimates were assigned to each combination of job title and chemical or group of chemicals.

Outcomes and predictive factors of vital pulp therapy in a large-scale retrospective cohort study over 10 years

Scientific Reports
This cohort study evaluated the long-term success/survival of vital pulp therapies (VPTs) after carious pulp exposure in adult teeth. Additionally, factors influencing long-term success were identified.
