    With the advancement of technology and scientific development, the survival of children undergoing cancer treatment has increased significantly. However, treatment sequelae can manifest even y ears after the end of therapy. Objective: To evaluate the dental pulp vitality of patients with head and neck parameningeal rhabdomyosarcoma and rhinopharyngeal carcinoma who received radiotherapy for local control of the neoplasia. Methodology: Fifteen pa tients were admitted to the study group and thirty patients to the control group. A total of 494 anterior teeth were analyzed. To assess the pulp vitality, use the pulse oximeter apparatus adapted for dental use (which has a sensor "Y"), it being possible to position the buccal and lingual or tongue of the dental element. The pulp sensitivity test was performed by cooling the dental surface, using the refrigerant gas applied with cotton swab to the tooth surface. Results: Student's t test (alpha = 0.05) was used to analyze the mean% SpO2 of the teeth of the study (N = 158) and control (N = 336) groups. The average oxygen saturation obtained in the teeth of the study group was 86.06%, and 90.05% in the control group. Demonstrating a statistically significant difference between groups (p <0.0001). Pearson's correlation test with 0.05 alpha adjustment was used to assess the correlation between the results obtained with pulse oximetry and the degree of sensitivity. The results demonstrate a negative correlation (r = 0.8525; p <0.0001) between the mean% SpO2 and the degree of sensitivity reported by the patients. Conclusions: The levels of pulp oxygenation saturation in irradiated patients were lower when compared to the control group. There seems to be a relatio nship between pulp oxygenation and tooth sensitivity. The lower the oxygen rate, the greater the sensitivity.

    AIM: To assess the interference of nail polish on the reading of peripheral oxygen saturation in patients with chronic obstructive pulmonary disease on the step exercise. METHODS: In this study, there was the inclusion of patients with chronic obstructive pulmonary disease, current non-smokers, of both sexes. Four different colours of nail polish were used in the present study (base, light pink, red and brown), randomly distributed among the fingers of the right hand, with the corresponding fingers on the opposite hand being controls. Saturation was measured at rest, with and without the polish, and also during the 4th, 5th and 6th minutes of the exercise programme. RESULTS: The experimental universe included 42 patients with ages of 62.9±8.7 years. In the exercise considered, the red colour reduced it in the fourth minute of the exercise (p=0.047). In contrast, the brown colour reduced saturation at rest and also during the course of exercise (p=0.01). CONCLUSION: In patients with chronic obstructive pulmonary disease, the red and brown colours interfered with the reading of the peripheral oxygen saturation during exercise. This study is registered at the Brazilian Register of Clinical Trials (Registro Brasileiro de Ensaios Clínicos) under No. RBR-9vc722.
