A New Criteria to Assess Quality of Obturation in Primary Teeth: KEDOO Classification

AIM: The success of the pulpectomy depends on adequate access, cleaning, shaping, and good-quality obturation. Evaluating the quality of obturation is the major tool that determines the success of the procedure. The present study aimed to assess the quality of obturation in all the canals of primary teeth and suggest a new classification. MATERIALS AND METHODS: A total of 1,000 radiographs of the pulpectomy procedure performed in primary molars were evaluated. The quality of obturation was assessed for each canal using the criteria given by Coll and Sandrian. The prevalence of each obturation criterion in every canal was represented in the form of a percentage. RESULTS: It was observed that among the mandibular primary molars, most of the mesial canals were underfilled, and in the distal canal, most of the canals were overfilled. Among the maxillary primary molars, most of the mesial canals were overfilled, more distal canals were underfilled, and with respect to palatal canals, optimal obturation was seen. CONCLUSION: The pitfalls of the previous classification were revised, and a new classification for assessing the quality of obturation was proposed, which is arch, segment, and canal specific. CLINICAL SIGNIFICANCE: The new classification will give a more precise assessment for the evaluation of various techniques and materials used for pulpectomy in primary teeth.
