Mandibular kinetics is composed of a series of complex movements regarding opening and closing and latero-lateral movements. The procedure for registration of this trajectory is condylography. This procedure represents a diagnostic method for monitoring and registering the movements of the mandibular condyles. The analysis starts from the most distal position of the condyle to the maximum propulsive point and latero-lateral maximum extensions. The aim of this examination is to compare the trajectory of movement of the mandibular condyle in patients with symptoms of TMD, in the acute phase and the trajectory after the treatment and corrections of intermaxillary relations. Materials and methods. The examination was carried out in 20 (10 men and 10 women) patients of PHO Denta Estetika Team Skopje. The patients were complaining about pain, limitation of movements and crepitations in the temporomandibular joint as well as difficult mastication. Condylographic measurements were made with the Kavo Arcus Digma digital condylograph. The registration of the movements was done in two sessions, before and after the treatment. Results. There was no statistically significant difference in temporomandibular condyle movement angles before and after the treatment in patients with TMD. There was a statistically significant difference in the value of Bennett?s angle. Easier and more accurate movements of mandible were noticed in the patients after the treatment.","PeriodicalId":52984,"journal":{"name":"Stomatoloski glasnik Srbije","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135504860","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}

Sudden fracture of instruments without previous warning signs, which occurs due to cyclic and torsional fatigue, represents the biggest problem and one of the most difficult complications during endodontic therapy. The aim of this research was to check the influence of diameter of the instruments on the appearance of cyclic fatigue in simulated canals in full rotation. Material and Method. The study analyzed 24 ProTaper Universal instruments (12 instruments with a diameter of 25 and 12 instruments with a diameter of 30) and 24 ProTaper Next instruments (12 instruments with a diameter of 25 and 12 instruments with a diameter of 30). The instruments were tested in an artificial canal stuffed in a metal block at an angle of 45? and a corner radius of 5 mm. The operating time of each instrument until fracture was measured, and then the number of cycles to fracture (NCF) was calculated. The length of the fractured fragments (FL) was measured with a Vernier caliper. Results. The number of cycles to fracture was higher (p < 0.001) in instruments of the ProTaper Universal group of diameter 25 (367.83 ? 17.00) compared to instruments of diameter 30 (329.33 ? 12.86) of the same group. The number of cycles leading to the fracture in instruments of the ProTaper Next group of diameter 25 (1189.33 ? 18.97) was higher (p < 0.001) compared to instruments of the same group of diameter 30 (971.08 ? 15.26).

In addition to the advantages of glass ionomer cements that have led to their wide application, hybrid glass ionomer cements have been developed to overcome the shortcomings in mechanical resistance. The aim of the study was to perform an ultrastructural analysis of restorations made from conventional and hybrid glass ionomer cements after recommended finishing procedures and application of a protective coating. Materials and Methods. This study analyzed 30 samples of conventional glass ionomer cement Fuji IX? and 30 samples of hybrid glass ionomer cement EQUIA Forte HT Fil?. The samples were prepared in cylindrical molds and divided into the three groups. The first group of samples, after adaptation, was left untreated and served as a control group. The second group consisted of samples that were finished with a cylindrical diamond bur with water cooling. The samples in the third group were finished and protected with appropriate coatings (G-COAT PLUS? and EQUIA Forte Coat?). The samples were analyzed using scanning electron microscopy. Results. The finishing procedures of Fuji IX? samples significantly reduced crack width (t = 3.42, p < 0.005; Z = 3.25, p = 0.001). Similarly, the crack width in EQUIA Forte HT Fil? samples was also significantly smaller in treated samples (t = 4.78, p < 0.001; Z = 4.28, p < 0.001). Ultrastructural analysis of both materials showed the complete absence of cracks in finished samples protected by coatings. Conclusion. Finishing of conventional and hybrid glass ionomer cements results in a reduction in the number of cracks as well as a decrease in their widths, and the protective coatings completely cover remaining cracks.","PeriodicalId":52984,"journal":{"name":"Stomatoloski glasnik Srbije","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135504846","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}

The failure of marginal adaptation leads to marginal leakage, passage of bacteria, fluids, molecules or ions between enamel and sealant, creating possibility for development of dental caries below the sealant. The aim of this study was to assess and compare microleakage of resin based sealant after acid etching and Er: YAG laser treatment of enamel. Materials and Methods An in vitro study included 30 premolars and molars extracted for orthodontic purpose, without any structural anomalies, and divided in the two groups of 15 samples. Group I included teeth with fissures sealed using resin based sealant (Helioseal-F, Ivoclar Vivadent AG, Liechtenstein) after enamel etching with 37% phosphoric acid. Group II consisted of teeth where fissures were sealed with resin based sealant (Helioseal-F, Ivoclar Vivadent AG, Liechtenstein) after enamel etching with Er: YAG laser (Fotona Light Walker Laser). Results In the group I, 10 (66.67%) samples demonstrated level 0 microleakage, 2 (13. 33%) samples demonstrated level 1 microleakage and 3 (20%) samples demonstrated level 3 microleakage. In the second group, 10 (66.67%) samples demonstrated level 0 microleakage, 1 (6.67%) demonstrated level 1 microleakage, 2 (13.33%) samples demonstrated level 2 microleakage and 2 (13.33%) samples showed level 3 microleakage. Descriptive statistics for microleakage resulted with mean score=0.73 for the first and second group. There was no statistically significant difference in chosen technique for etching occlusal enamel (37% phosphoric acid or Er: YAG Laser radiation) p>0,05 (p=0,98), when placing fissure sealants.

The surgical procedure and healing of the wound result in scar formation, which impacts oral soft tissue aesthetics. The aim of this study was to evaluate the characteristics of a postsurgical scar after gingival recession treatment using the mucosal scarring index (MSI). Material and methods In accordance with the MSI, ten standardized and calibrated photographs of the postsurgical site, taken 3-6 months following the surgical procedure, were analyzed. That included the evaluation of six parameters: scar appearance, scar length, suture marks, contour, color, and overall appearance. 30 professionals divided into the three groups conducted the scar analysis: 10 dental students (S), 10 periodontology and oral medicine residents (SS) and 10 periodontal specialists (SP). Results the average MSI values showed the following results: S: 3.63 ± 2.71, SS: 3.63 ± 2.83 and SP: 3.12 ± 2.75. There was no difference between the MSI values obtained in the three groups (p=0.544). Conclusion Due to the similar MSI values among all the groups, a conclusion may be drawn that by the application of this index, the aesthetic evaluation of the postsurgical scar after the gingival recession treatment can be done in a fast and simple way.
