In a new study, it was found that with coverage of primary molars with sealants, these teeth are less prone to caries. The researchers also found that the sealants delay the need for restorative work on these teeth. Previous researches have focused on the benefits of sealants for permanent molar teeth; unfortunately, few studies have addressed their effects on the primary teeth. The present study which was conducted by Michael Hong and his colleagues shows that their findings provide the necessary evidence to support sealants in young children.

Introduction: Tooth extraction generates a certain level of stress and anxiety; furthermore, these factors can produce a sudden variation in blood pressure even in normotensive patients. This study aimed to determine the variation in blood pressure values and its relationship with the level of anxiety in patients undergoing dental extractions.
Methods: In total 110 adult patients, requiring simple dental extractions were selected and treated at the Surgery outpatient Clinic. Thus, the modified Corah questionnaire was applied to determine the level of anxiety and blood pressure control was performed by the auscultatory method, using a Riester © Duplex® 2.0 Stethoscope. The Riester exacta® aneroid sphygmomanometer, complying with the European standard EN1060, was used in the preoperative period, 5 minutes after the application of the local anesthetic and in the immediate postoperative period. Data were analyzed at a statistical confidence level of 95%.
Results: 98.2% (n = 108) showed a variation in blood pressure values between the pre- and postoperative time intervals, however, a significant variation occurred in the systolic pressure; the highest values were recorded in the immediate postoperative period. There was greater variability of blood pressure in patients with moderate to severe anxiety than in patients with mild anxiety. Patients from 50 – 60 years of age showed a higher variation in blood pressure values during the procedure.
Discussion: There was a significant variation in blood pressure during dental extractions in normotensive patients, and the level of anxiety shown by patients was related to the blood pressure values measured in this study.

Cementoblastoma is a benign, slow-growing odontogenic tumor. Its most common symptoms are pain and inflammation, but the patient can be asymptomatic as well. Radiographically it can be seen as a radiopaque mass attached to the affected tooth and the recommended treatment is its extraction along with the affected tooth. This case represents a cementoblastoma located in the right mandible first molar of a symptomatic female patient where a surgery to extract both, the lion and the tooth, was performed.
