EVALUACIÓN CLÍNICA Y RADIOGRÁFICA DE UNA PASTA ACUOSA DE HIDRÓXIDO DE CALCIO - IODOFORMO EN EL TRATAMIENTO DE PIEZAS PRIMARIAS NECRÓTICAS (SEGUIMIENTO DE TRES MESES)

Aim: To evaluate the efficacy of a calcium hydroxide iodoform aqueous paste on the treatment of primary necrotic pieces (3 month follow-up). Materials and Methods: 28 dental pieces with pulp necrosis belonging to 25 children between 3 and 8 years old who attended the odonthologic clinic of the Catholic University of Cuenca and received pulpectomies through mechanical preparation with files and chemical treatment with sodium hypoclorite and were sealed with calcium hydroxide iodoform aqueous paste. Clinical radiographic controls of the variables: pain, fistula, mobility, and periapical and interrradicular radiodiolucency were carried out during 90 days. After 90 days all the pieces were asymptomatic, 93.1% had absence of tooth mobiity, 79.3% had no periapical lesion, 17 pieces were found to be subobturated. Conclusions: This sudy shows that the primary pieces with necrosis which underwent pulpectomy obturation treated with calcium hydroxide iodoform aqueous paste were succesful both clinically and radiographically after 90 days. This study should hbe extended and compared to other techniques
