Many factors affect dental pulp pulse oximetry technique (PO), as recipient
signals may reflect not only pulpal blood flow, but also may mixed with signals of blood flow of the
periodontal or gingival tissues. To evaluate the effect of isolation of
the periodontal tissues apart from the
dental crown using rubber dam; during pulpal blood oxygenation of the deciduous molars.
Few researchers have made a comprehensive study of the morphology of the
root canals of the primary molars. Thorough knowledge in internal anatomy of the primary molars is
useful in reducing the problems of endodontic therapy arising due to the ana
tomical variation in root
canals, which are clinically difficult to be detected.
Exploration the root canals of primary molars with regard to its number, variations, and accessory canals
in the furcation region.
the complication of the internal anatomy of primary molars causing complication in
endodontic treatment so the results of this study suggest avoiding pulpectomy in primary molars where
ever possible.
Primary tooth crown shapes and dimensions are poorly
investigated in Arab Countries.
The aim of this study was to establish normative data on crown
morphological description and dimensions of primary molars for the
Syrian children.
