•This literature deals with studies describes pertaining to pulpal morphology especially the variances of the root canal system in the palatal roots of maxillary molars.

• This research has approach to become more evident that the pulp canal space is complex and varied.  More techniques has been developed in radiographic, with multiple angles.

•It is an important issue paid to the fact that some maxillary molars possess two distinct palatal roots with its own root canal system.

•60 % of failure is attributed to incomplete obturation (missing canal). •Mesiodistal radiograph , buccolingual radiograph; and in a cross-section view of the palatal root demonstrates two separate canals.

•The clinical cases shown in figs. 5 to 7 demonstrate variations of palatal root morphology.

• Fig. 5 shows a maxillary molar that has a furcating canal in the palatal root with two separate foramina. Fig. 6 shows a maxillary first molar that was treated when the patient was 22 years of age .The palatal root demonstrates two separate canals in the palatal root. Fig. 7 depicts a maxillary molar with two palatal roots, each of which has its own canal.

Clinical  significance :

The practitioner should be aware of variations in the canal system of the palatal roots of maxillary molars so that they can be treated more effectively
