تأثير الحاجز المطاطي في قيمة أكسجة اللب السني للأرحاء المؤقتة

Background& Objective: 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.

Materials & Methods: 40 intact lower first primary molar from 31 healthy male child, 4-8 years old, without any systemic disorder, and systemic saturation more than 95% were studied.

Values of pulpal saturation of these teeth; measuring with ear probe without rubber dam isolation were compared with values of saturation of the same teeth using rubber dam isolation; depending on T-student test (P<0.05).

Results: statistical study revealed no significant differences between pulpal oxygenation mean values before and after rubber dam isolation of the lower first primary molar.

As the mean value without isolation was 87.55% ± 2.124, and 87.53% ± 2.148 with the rubber dam.

Conclusion: dental pulp PO technique is a simple pulpal test, don't need rubber dam application, though; it still in need of researches and development.
