The drugs have been shown to have a role in the regulation of bone cell function and as a result affecting the orthodontic tooth movements. The aim of this study was to determine the effect of Amitriptyline and Sertraline on the tooth movement, root resorption and alveolar bone remodeling after load application in dogs. \u0000Materials and Methods: In this experimental study, 9 male dogs were randomly divided into three groups, first group sertraline, second group Amitriptyline and the control group (normal saline). A nickel titanium spring (200 gr) was used between second premolar and canine after 1st premolar extraction. After 2 months, the reduction of distance between 2nd premolar and canine was measured. The percentages of root resorption and bone formation were determined. The data were analyzed using repeated measures analysis at significance level of 0.05. \u0000Results: In the three groups of amitriptyline, sertraline and control, the mean of teeth movement (p value = 0.483), external root resorption (p value = 0.608), total bone mineral density (p value = 0.078), bone formation percentage (p value = 0.616) and immature and lamellar bone formation (p value = 0.083), there was no statistical difference in any group and in premolar teeth \u0000Conclusions: The rate of tooth movement and the percentages of bone formation and root resorption in dogs decreased with systemic administration of amitriptyline and sertraline; although this reduction was not statistically significant in comparison with control group.

This study aimed to compare the accuracy of two periapical radiographic and digital biting techniques in assessing bone resorption in posterior teeth of patients with chronic periodontitis. \u0000Materials and Methods: This descriptive-analytical study was performed on 36 samples of interproximal surfaces of posterior teeth in patients with chronic periodontitis, candidate of flap surgery referring to the department of periodontitis, faculty of dentistry, Islamic Azad University of Isfahan (Khorasgan) in 2015. First two methods of imaging include periapical and digital bitewing were performed and the necessary distances were measured by a radiologist. Then, during surgery, and before the bone contour correction, the distance from the reference point to the alveolar bone shaft (gold standard) was measured by a Williams probe. Data were analyzed using Paired t-test.

The average difference of amount of bone resorption in bitewing was 0.2 ± 0.12 mm and there was no significant difference between estimated mean value (p value = 0.01). Average difference of amount of bone resorption in periapical to clinical method was 0.87 ± 0.26 it was significant difference (p value = 0.001). \u0000Conclusion: According to result, the use of bitewing radiography to determine the rate of bone resorption in posterior teeth is preferable to periapical radiography.","PeriodicalId":221865,"journal":{"name":"Journal of Isfahan Dental School","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126460025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These materials may remain on the tooth for a long time, and other areas of the tooth may decay. The purpose of this study was to present the best method for surface preparation a fissure sealant material (Icon) and composite restoration \u0000Materials and Methods: In this experimental laboratory study, 40 samples of composite restorative material were prepared in 4 groups of 10 discs of 6 mm in diameter and 2 mm in height. Total etch bonding agent was used in the first, second and third groups without surface preparation, with the use of drills and 37% phosphoric acid, and after drilling, respectively. In the fourth group, self-etch bonding agent was used after drilling. After that, Icon resin material was placed on the surface of the composite in a disc of 4 mm with height of 2mm in diameter and was cured. When the samples were thermocycled and incubated, their bonding strength was evaluated with Instron testing machine. Data were analyzed by one-way variance statistical ANOVA tests, Tukey test (p value < 0.05). \u0000Results: The mean value of bond strength of Icon to resin composite was significantly different among the 4 groups (p value < 0.05). The fourth group presented the greatest bond strength value while the third group had the lowest bond strength. \u0000Conclusion: When repairing fissure sealant, particularly Icon using resin composite, the best results of bond strength are achieved through surface roughening with drills and the application of self-etch bonding agents with a mild pH. Acidic etching agents (37% Phosphoric acid), however, have probably destructive effects on bond strength.","PeriodicalId":221865,"journal":{"name":"Journal of Isfahan Dental School","volume":"135 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124260222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
