RESUMO

ABSTRACT Objective: To assess the relationship of ɑ and ß angles of maxillary impacted canines with maxillary lateral incisor root resorption. Material and Methods: For this, 40 patients (between 11 and 45 years) with impacted maxillary canines presenting to a private orthodontic clinic were evaluated.20% of the cases were male and 80% were female. The ɑ and ß angles were measured on panoramic radiographs to determine the angulation of impacted canine. CBCT scans had been taken by ProMax 3D CBCT system were used to examine lateral root reorption. The relationship between the size of ɑ and ß angles of impacted maxillary canines and root resorption in the adjacent maxillary lateral incisor was analyzed using SPSS version 22. Results: The mean size of ɑ and ß angles had no significant correlation with the presence/absence, location, or severity of root resorption in the adjacent lateral incisor or the buccolingual position of impacted canine. The ɑ and ß angles in impacted maxillary canines cannot be used to determine the incidence or severity of root resorption in the adjacent lateral incisor. Conclusion: No significant association between ɑ and ß angles and incidence or severity of root resorption in the adjacent lateral incisor was found.

RESUMO

Diabetes mellitus [DM] is caused by hyperglycemia, resulting from defective insulin secretion or function. It is widely believed that the antioxidant micronutrients obtained from plants afford significant protection against diseases like diabetes mellitus. Present study was aimed to examine the effects of Persian shallot [Allium hirtifolium Boiss] on FBS, HbA1c, insulin, Triiodothyronine [T3] and Thyroxine [T4] levels in type 1 diabetic rats. Thirty two male Wistar rats were divided into 4 groups of 8. The diabetic groups received 100 and 200 mg/kg Persian shallot extract, diabetic control and normal control received %0.9 saline for 30 days. At the end of treatments, fasting blood specimens were collected. The levels of FBS, HbA1c, insulin, T3 and T4 were measured. Our findings indicated that hydroalcoholic extract of Persian shallot significantly decreased serum levels of FBS and HbA1c in treated groups [in a dose dependent manner] [P<0.05]. The serum levels of insulin and T3 slightly increased by Persian shallot but the T4 serum level was declined. These beneficial effects of Persian shallot extracts in diabetic rats could probably be due to the antioxidant capacity of its phenolic and diallyl disulfide content
