| Objectives: Clinical and radiographic evaluation of the premedicated direct pulp capping using formocresol (PDC) versus conventional direct pulp capping using calcium hydroxide (CDC) in human carious primary molars. Study design: A total of 120 vital primary molars with pinpoint exposure during caries
removal in 84 patients aged 4-5 years were selected. In the PDC group (n = 60), 20% Buckley’s formocresol solution, and in the CDC group (n = 60), calcium hydroxide powder were applied to the exposure sites
followed by placement of zinc oxide-eugenol base. Teeth were restored with preformed stainless steel crowns.
Clinical and radiographic evaluations of the treatment outcomes were performed at regular intervals of 6
and 12 months, respectively, for two years post-operatively. Results: The prevalence of spontaneous pain,
sensitivity on percussion, and fistula were significantly higher in the CDC group compared to the PDC
group (P < 0.05). The number of teeth exhibiting periapical/furcal radiolucency or external/internal root
resorption was also higher in the CDC group (P < 0.05). The clinical success rate of the PDC was 90% compared to the 61.7% of the CDC (P < 0.05). The radiographic success rates of the PDC and CDC groups
were 85% and 53.3%, respectively (P < 0.05). Conclusion: It seems formocresol premedicated direct pulp
capping could safely be used as a substitute for conventional direct pulp capping. |
