To determine the oxygen saturation levels (SaO2) of the pulp of permanent molars of adult patients who will need to perform direct pulp capping due to pulpal caries exposure, through pulse oximeter evaluation before and after treatment with MTA or glass bioactive 45S5.

Inclusion Criteria

Patient volunteering to participate in the study, in the age group of 18 to 40 years. Presence of upper and lower permanent molars and premolars with carious lesion. Patient with no history of night pain or spontaneous pain. Pulpal sensitivity to cold test with positive response. Radiographic examination showing deep caries with an image suggestive of proximity to the pulp chamber without signs of periapical pathology. Systemically healthy patient. Patient should have the first, second or third premolar or molar contralateral to the tooth that will be performed sound CPD, as it will be considered the control.

Exclusion Criteria

Presence of pain.Teeth affected by trauma. Teeth with color changes; teeth with periodontal changes pocket more than 3mm; mobility and gingival edema; presence of pain on apical palpation; vertical and horizontal percussion; and teeth with pulp necrosis. Teeth with extreme persistent pain in response to pulp sensitivity test with cold and exposure to iatrogenic pulp.

Primary Outcome Measures

Name	Time	Method
It will be the evaluation of the blood oxygen saturation rate (SaO2) arterial and pulp and the response to the cold sensitivity test (TSF) before direct pulp capping (CPD), and at intervals of 1, 3, 6, 12 and 18 months after CPD in two groups (A Bioactive Glass 45S5 and B MTA). Data including pain (percussion / spontaneous / night) after treatment, tooth sensitivity, radiographic signs of periapical pathology, and dentinal bridge formation will be evaluated. Teeth that remain asymptomatic with a positive response to sensitivity tests and / or saturation of pulp oxygen considered normal and / or radiographic evidence of formation of hard tissue bridges without radiographic signs of periapical pathology will be considered successful.
