Assessment of Pulpal Oxygen Saturation in Caries-free and Carious Maxillary Primary Central Incisors Using a Customized Dental Pulse Oximeter.

Introduction: Pulpal status is best determined by assessing the pulp vitality, which proves to be important yet sceptical with the use of conventional thermal and electrical testing methods. The use of pulse oximetry helps to arrive at a definitive diagnosis by detecting the pulpal oxygen saturation.

Aim: To assess and compare the pulpal oxygen saturation in caries-free and carious maxillary primary central incisors using a customized dental pulse oximeter sensor probe.

Evaluation of Embrace WetBond and Helioseal-F sealant retention with and without a Self-etch adhesive: A 12 month follow-up.

Background: Pit and fissures on the young permanent tooth are ideal in harbouring dental plaque and calculus. Hence it is important to provide a preventive agent to protect against dental caries. Aim: To evaluate the retention of two different pit and fissure sealants with and without a self-etch adhesive in the first permanent molars for a period of one year.
