“…No significant statistical correlation was found between the levels of body SaO 2 levels and heart rate on the patient's index finger and teeth (r=-0.02; p=0.85). This finding is in line with previous investigations (17,19,26).…”

“…In the present study, 68 patients with a mean age of 26 years showed mean baseline pulp SaO 2 of 85.1% in maxillary central incisors. This result is in line with some previous studies (17,18) that showed similar pulp SaO 2 levels in this same tooth group. Conversely, in other investigations (18,19), pulp SaO 2 levels of 91.29% and 79.3% were reported.…”

“…The limitations associated with the subjective nature of thermal and electric pulp sensibility tests have stimulated studies with pulse oximetry, a technique that is capable of detecting changes in dental pulp status. Studies involving pulse oximetry in endodontics have shown that this is a promising resource with potential use in clinical practice, as it is non-invasive, easy and simple to apply, and yields objective measures (11,12,13,(16)(17)(18)(19)(20). However, there is a scarcity of studies on pulp response in teeth subjected to bleaching.…”

The present study assessed oxygen saturation (SaO2) levels before, during, and after at-home bleaching treatment in the pulps of healthy maxillary central incisors. SaO2 levels were measured in 136 healthy maxillary central incisors using a pulse oximeter. The bleaching protocol consisted of 10% carbamide peroxide gel placed in individual trays and used for four hours daily for 14 days. SaO2 levels were assessed before bleaching (T0), immediately after the first session (T1), on the 7th day of treatment (T2), on the 15th day (the day following the last session) (T3), and 30 days after completion of the bleaching protocol (T4). Data were statistically analyzed using generalized estimating equations (GEE), Student’s t test (p<0.05) and Pearson’s correlation. Mean pulp SaO2 levels were 85.1% at T0, 84.9% at T1, 84.7% at T2, 84.3% at T3, and 85.0% at T4. Gradual reductions in SaO2 levels were observed, with significant differences (p<0.001) during the course of home bleaching treatment. However, 30 days after the end of the bleaching protocol, SaO2 levels returned to baseline levels. Home bleaching caused a reversible transient decrease in SaO2 levels in the pulps.

“…The mean baseline pulp SaO 2 level in this sample of 120 healthy maxillary central incisors was 84.76%. This value is higher than the 81.25% reported by Stella, et al 25 (2015) in an analysis of 110 maxillary central incisors, and similar to the 84.80% reported by Bargrizan, et al 26 (2016) in a sample of 190 healthy central incisors. Oxygen saturation values higher than those of this study (92.60%) were measured in maxillary incisors by Kataoka, et al 18 (2016).…”

Effect of dental bleaching on pulp oxygen saturation in maxillary central incisors - a randomized clinical trial

et al. 2019

Objective To assess pulp oxygen saturation levels (SaO 2 ) in maxillary central incisors after dental bleaching. Materials and Methods 80 participants (160 teeth) were randomly allocated to four groups: G1 In-office bleaching with two applications of 35% hydrogen peroxide (HP) (20 minutes), followed by at-home bleaching with 10% carbamide peroxide (CP) (2 hours/day for 16 days); G2 - Same protocol as G1, plus desensitizing toothpaste; G3 - In-office bleaching with 35% HP and one application of placebo gel (20 minutes), followed by at-home bleaching with 10% CP (2 hours/day for 16 days); and G4 - Same protocol as G3, plus desensitizing toothpaste. Pulp SaO 2 levels were measured before (T0) and immediately after (T1) in-office bleaching; on the 5 th (T2), 8 th (T3), 12 th (T4), and 16 th days of at-home bleaching (T5); and on the 7 th (T6) and 30 th (T7) days. Mean (SD) pulp SaO 2 levels were compared within groups by generalized estimating equations (GEE) and Student’s t-test (P<0.05). Results Mean pulp SaO 2 at T0 was 84.29% in G1, 84.38% in G2, 84.79% in G3, and 85.83% in G4. At T1, these values decreased to 81.96%, 82.06%, 82.19%, and 81.15% in G1, G2, G3, and G4 respectively, with significant difference in G4 (P<0.05). During home bleaching, pulp SaO 2 levels varied in all groups, with 86.55%, 86.60%, 85.71%, and 87.15% means at T7 for G1, G2, G3, and G4, respectively; G2 presented significant difference (P<0.05). Conclusions Pulp SaO 2 level in maxillary central incisors was similar at baseline, reducing immediately after in-office bleaching, regardless of using desensitizing toothpaste and increasing at 30 days after dental bleaching.
