Iv. Nosrat et Ca. Nosrat, REPARATIVE HARD-TISSUE FORMATION FOLLOWING CALCIUM HYDROXIDE APPLICATION AFTER PARTIAL PULPOTOMY IN CARIOUSLY EXPOSED PULPS OF PERMANENT TEETH, International endodontic journal, 31(3), 1998, pp. 221-226
In a prospective study, partial pulpotomy was performed on six permane
nt molars with deep carious lesions and pulpal involvement. The bleedi
ng pulp was irrigated with normal tap water until bleeding had stopped
and the exposed pulp was covered with calcium hydroxide followed by z
inc oxide eugenol, and finally covered with a semipermanent restoratio
n. All teeth showed hard tissue barrier formation, both clinically and
radiographically, within three months and were free from subjective a
nd objective symptoms through the observation period (average observat
ion period was 26 months). The patients also experienced the therapy p
ositively. These findings and those of others have helped gain more re
cognition for partial pulpotomy as a strong possible alternative thera
py when pulps are exposed by deep carious lesions and a bleeding pulp
is exposed during the excavation process. The rationale for this thera
py is to remove the infected and/or inflamed pulpal areas beneath the
carious lesion and disintegrated tissue. A rapid and simplified proced
ure would allow the general practitioner to perform this procedure whe
n necessary at dental clinics, without specialist facilities under con
ditions that avoid unnecessary contamination of the pulp.
