Abstract:
OBJECTIVETo investigate different angle projection technique for clinical judgment of obturation quality of molars with multiple root canals.
METHODSEighty-seven maxillary first molars with second mesiobuccal canal (MB2) and 105 mandibular first molars were selected. The canals were instrumented by Ni-Ti rotary instruments and obturated with lateral condensation technique. To judge the obturation quality of the root canals, the radiograph was taken at a horizontal angles of 0 and 20 - 30 degrees from distal direction of the tooth after the treatment.
RESULTSFor maxillary first molars, periapical radiographs showed 23.0% of MB2. Distally angulated radiographs showed 81.6% of MB2. For mandibular first molars, periapical radiographs showed 38.1% of mesiobuccal and mesiolingual canals, and distally angulated radiographs showed 90.5% of two mesial root canals.
CONCLUSIONSMost buccal-lingual distributed root canals of the first molar can be shown more clearly by distally angulated radiographs.
