Anatomical features and color characteristics of teeth may affect the recipient
signals' nature during dental pulp oximetry, enamel tissue thickness may consider of the most important
factors. This clinical study aimd to evaluate the effect of enam
el tissue thickness of the upper premolar
crown on the accuracy of dental pulp oxygen saturation readings.
The results of this study indicate that there is a considerable effect of the dental tissue
thickness on the dental pulp oxygenation measurement. So; it is of important to find the suitable
adjustments on the PO apparatus, probe, or programs, in order to gain less effect of the anatomical
variances between teeth, and thus increasing pulse oximetry measurement accuracy.
Hypoxemia is defined as the condition of insufficient oxygen saturation of the blood. Hypoxemia considered as one of most dangerous problem encountered pulmonologists cardiologists and critical care nursing, it complicate the ICU stay of many childre
n every year with significant associated mortality, it causes more than two million deaths worldwide in children less than five years of age. The study aimed to identify the best pulse oximetry placement among three placements (thumb, big toe, and ear-lobe). The study was conducted in the department of intensive care, and incubators, in Obstetric and Pediatric Hospital, and Al-Assad Hospital in Lattakia city, the sample consisted of 70 children. The results revealed that both the thumb and toe sites has an equal sensitivity in detection of hypoxemia.
