To emphasiase that there is possible two palatal roots in maxillary molar clinically & radiographs and compare with other reports
•N=15 patients who had endodontic treatment on 16 maxillary molars with two palatal roots., and 6 extracted teeth or slides, eight male patients and seven female patients .
- 15 patients who had a double palatal roots in maxillary teeth.
- the instruments are labeled R-L as MBu, MLi, DBu, DLi then radiograph was taken.
- Access opening square outline form was used. classify root morphology of maxillary molars with two palatal canals, then radiographs evaluated.
these reports have been tabulated for comparison (Table 1).
•Most highlighted Results:
1.The anatomy of the teeth studied had variations in length, curvature, and divergence of root morphology.
2. Classification of maxillary teeth with two palatal canals :
- Type I have two widely divergent palatal roots that are often long and tortuous
- type II maxillary molar (Figs. 6, 7, and 10) has four separate roots also but the roots are often shorter, run parallel, have buccal and lingual root morphology, and have blunt root apices.
3.Prognosis for treatment of these four rooted molars is important in success of RCT
It is hoped that this report will stimulate studies of larger numbers of similar types of anomalous root canal anatomy. Christie WH, Peikoff MD and Fogel HM
