To determine if there are any significant differences between the prognoses of pulpectomies done on first and second primary molars of the upper and lower dental arch.
Material and methods
Study Design: The clinical study included 55 children who had undergone 86 pulpectomy treatments, 41 on the first molars and 45 on the second molars. The root canal filling material consisted of a paste based on Walkhoff formula, containing Kri-1, calcium hydroxide and meta-cresol formaldehyde. The same clinician carried out all pulpectomies.
After the analysis there were a total of 7 treatment failures (3 in the upper arch and 4 in the lower). Four of the 7 failures were first primary molars and three were second primary molars. Statistics: There were no significant differences in the prognoses of the different kinds of primary molars.
The anatomy of the primary molars changes considerably. Significant differences were not observed in the prognosis of different types of primary molars after pulpectomy.
