RESUMO
La saliva, compuesta principalmente por 99% de agua y 1% de moléculas orgánicas e inorgánicas, mantiene un rango de pH de 6.0 a 7.5, pero puede verse alterada por ciertos factores. En este estudio se determinó la variación del pH salival, luego de la aplicación tópica manual en mucosa masticatoria y órganos dentarios con aceite de girasol ozonizado de 300 mEq/kgO2, en jóvenes estudiantes de entre 21 a 23 años, como agente de neutralización en los cambios de pH. Se realizó un estudio comparativo longitudinal en 13 sujetos después de su cepillado dental; se tomaron dos muestras en saliva estimulada con el test estandarizado Saliva-Check BUFFER (GC®EUROPE). La medición basal de pH fue 7.66 ± 0.09, cifra por encima del rango normal; después de la aplicación del aceite de girasol ozonizado (O3MX®300IP) el pH fue de 7.27 ± 0.19, estableciéndose una variación de 0.28 ± 0.48, t = 8.04, p < 0.05 (0.000). Este estudio revela una caída significativa en el pH salival después de aplicar aceite de girasol ozonizado, lo que sugiere su potencial como buffer del pH salival. Se necesitan más investigaciones para explorar las implicaciones clínicas para el manejo de la salud oral (AU)
Saliva, primarily composed of 99% water and 1% organic and inorganic molecules, typically maintains a pH range of 6.0 to 7.5 but can be influenced by various factors. This study aimed to assess the variation in salivary pH following manual topical application of 300 mEq/kgO2 ozonated sunflower oil to the masticatory mucosa and dental structures in young individuals aged 21 to 23 years, using it as a pH-neutralizing agent. A longitudinal comparative study was conducted on 13 subjects after dental brushing. Stimulated saliva samples were collected using the standardized Saliva-Check BUFFER Test (GC®EUROPE). An initial baseline pH measurement of 7.66 ± 0.09 was obtained, which was above the normal range. Following the application of ozonated sunflower oil (O3MX®300IP), the pH dropped to 7.27 ± 0.19, indicating a variation of 0.28 ± 0.48 (t = 8.04, p < 0.05 (0.000). In conclusion, this study reveals a significant decrease in salivary pH after applying ozonated sunflower oil, suggesting its potential as a salivary pH buffer. Further research is needed to explore the clinical implications for oral health management.(AU)

PURPOSE: Thus far, little attention has been paid to bariatric surgery (BS) in patients with severe obesity (SO) and cirrhosis with portal hypertension (PH). To address this knowledge gap, we systematically reviewed the available literature and evidence about BS in patients with SO and cirrhosis with PH. We inform on the perioperative and long-term outcomes of this intervention. MATERIALS AND METHODS: Articles were identified in MEDLINE, SCOPUS, LILACS, and SCIELO, and included if they analyzed SO patients with clinically significant PH and reported the characteristics and outcomes of BS. RESULTS: Six articles, including 32 patients, were included. The most frequent type of BS was sleeve gastrectomy performed in 27 patients. Perioperative transfusions were often not required, with only one case report describing the use of 1 unit of packed red blood cells post-operatively. Neither intraoperative nor post-op deaths were reported. All patients reported significant weight loss with improvements in comorbidities during the follow-up periods. Overall, 27 out of 29 patients had T2DM resolution, and 13 out of 23 had arterial hypertension resolution. One study reported improvements in the parameters of fibroscan. CONCLUSION: This systematic review described the outcomes of BS among patients with SO with cirrhosis and PH. Performing this kind of surgery among these patients appears safe and associated with acceptable perioperative and long-term outcomes. However, further studies are required to provide evidence-based, strong recommendations.
