Aim:The present investigation was undertaken to compare the tissue dissolving
ability of adult and young intact human pulp tissues using different sodium
hypochlorite concentrations.
Materials and methods: A total of 72 intact human pulps extirpated during routine
RCT from two age groups (36 adult and 36 young pulps) were experimented with.
Each group was divided into 4 equal subgroups of nine pulps each (n=9). Extirpated
pulps were placed separately in glass test tubes and submerged in the specified body
warm sodium hypochlorite solutions of different concentrations namely, 2.6%, 1.3%,
and 0.7%. The fourth subgroup of pulps was submerged in distilled water to act as a
control. Closed test tubes were then subjected to ultrasonic agitation until complete
dissolution occurred. Time lapse until pulp tissue dissolution was recorded and
results were statistically analyzed. Results: Distilled water was not able to dissolve
any of the tested pulp tissues. All the experimented sodium hypochlorite
concentrations dissolved pulp specimens completely. Time needed ranged from a
minimum of 2.67±1 minutes in young pulp specimens at 2.6% cone. to a maximum
of9.67 ±3.7l minutes in adult pulp specimens at 0.7% cone. An inverse relation was
found between sodium hypochlorite concentrations and the time needed for complete
pulpal dissolution both in adult and young pulps. Young pulps dissolved in less time
as compared to adult pulps. The difference was found to be statistically significant.
Recommendation: Within the limits of this study it is recommended to use a 2.6%
concentration of sodium hypochlorite for the adult pulps and 1.3% for the deciduous
teeth during cleaning and shaping to affect complete pulp tissue dissolution in 3
minutes for the former and 4 minutes for the later cases. |
