Influence of the Gingival Tissues on the Measured Saturation Level of the Dental Pulp Blood Flow

Summary/Abstract: Pulse oximetry is a method by which the oxygen saturation of the blood is measured. It is based on the specific absorption of red and infrared light from the hemoglobin. In dentistry, when teeth are tested by pulse oximeter, the oral mucosa could change the light signal entering the photodetector of the device. The aim of this study is to investigate the influence of the gingival tissues on the results when teeth are tested by pulse oximeter. To realise the goal, 44 teeth of 22 patients aged 23 – 29 years are examined. The teeth аre examined with pulse oximeter Contec CMS 60 D by positioning the diodes on the labial side of the teeth and on the photodetector from the oral. Two tests are conducted on each tooth. The first is by directly attaching the probe to the tooth. In the second test, the gingival tissues are isolated by condensation silicone.The following mean values ​​of saturation of the pulp are determined – in the group of direct examination of the teeth: 83% ± 1%; when the gingiva is isolated with silicone: 83% ± 1%. Analysis by SPSS v.19 show that there is no statistically significant difference between the measured saturation of the teeth in the two groups. Gingival tissues does not affect the results obtained and does not change the measured saturation levels of the dental pulp. Pulse oximetry can be used for vitality test of the teeth without the need for gingival tissues to be isolated.
