Abstract: Background: Despite the high success rates reported with the use of a five minute application of formocresol it has been postulated that it may be applied for a lesser amount of time and still achieve equivalent results. Few studies have adequately addressed the effects of the medicament on permanent successors and exfoliation times. Furthermore, the effects of shorter application times on success rates have not been adequately reported. Objectives: To assess the clinical and radiographic outcomes of a one minute application of full strength Buckley’s formocresol with concurrent hemostasis using the medicated cotton pledget in human primary teeth. To evaluate the effect of this technique on their successors and to evaluate the exfoliation times in comparison to the contralateral non-pulpotomized tooth. Methods: Using a retrospective chart review, clinical and radiographic data were available for 557 primary molars in 320 patients. Descriptive statistics and regression analysis were used to assess outcomes. Results: 99.3% clinical and 89.8% radiographic success rates were obtained. Internal root resorption (4.85%) and pulp canal obliteration (1.97%) were the most frequently observed radiographic failures. Sixty-five and half percent exfoliated at the same time as their contra-lateral counterpart and 28.8% exfoliated earlier (p<0.001). There was no difference in the number of enamel defects of succedaneous teeth between treated and control teeth (p>0.05). Conclusions: Success rates for the modified technique are comparable to techniques that use the five-minute dilute or full strength solutions reported in the literature. The one minute technique had no clinical effect on exfoliation times or incidence of enamel defects on succedaneous teeth. The one minute full strength formocresol technique is an acceptable alternative to published traditional techniques.
