Due to its brittleness, there is a constant need to improve its mechanical properties. In this regard, in the research we started from the assumption that increasing the proportion of powder during the preparation of plaster improves its mechanical properties. The aim of this research wasto determine the significance of the change in the ratio of powder and liquid to the mechanical characteristics of plaster (compressive strength). Material and methods: Three types of plaster were used in the research: type 2, 3 and 4. For each type of plaster, three samples were made with different ratio of powder and amount of water (n = 9). After 24 hours, the samples were analyzed at the Faculty of Mechanical Engineering in Niš, on a universal testing machine. Results: Plaster type 2 showed the lowest values of compressive strength, and higher values of types 3 and 4, regardless of the ratio of plaster powder and water. As the powder content increased, the compressive strength of the samples increased. Conclusion: In order to improve the compressive strength, the proportion of powder in the liquid phase can be increased during the preparation of the material without visible changes in its structure.","PeriodicalId":39229,"journal":{"name":"Acta Stomatologica Naissi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71202582","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 extent of the atrophy may vary, involving the superficial skin extending upto the underlying bone. The clinical features of PRS include craniofacial, neurologic, ophthalmic and dermatological manifestations, which result in various functional and psychological problems. PRS and linear scleroderma belong to the same disease spectrum. There can be demarcating line between the normal and abnormal skin seen in PRS, termed as \"en coup de sabre\". PRS is most commonly seen in females and involves the left side of the face. Method: We hereby report a case of PRS in a young girl presenting with en coup de sabre appearance on the right side of face. Results: Microsurgical facial reconstruction of the affected side is known to be the gold standard method for correction of the facial symmetry. In our case, the patient is currently kept under long term follow up and cosmetic surgical treatment will be planned once the atrophy attains stability. Conclusion: The association of PRS with linear scleroderma may present difficulty in its diagnosis. Hence, careful recording of the history and clinical examination with appropriate investigations can aid in establishing the correct diagnosis.","PeriodicalId":39229,"journal":{"name":"Acta Stomatologica Naissi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71202602","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 etiology of orthodontic anomalies is multifactorial, complex and conditioned by numerous genetic and non-genetic factors: endogenous and exogenous. Prevention of orthodontic anomalies is possible if we have an insight into the most common etiological factors. Goal: To assess the frequency of individual etiological factors and assess the overall risk of orthodontic anomalies in children in suburban environments. Materials and methods: The research was conducted on 115 children, first grade elementary school pupils (28.68% of all 1st grade students), average age of 6.8 years, from 4 settlements around Novi Sad: Kisač, Kać, Veternik, and Futog. The research was conducted in the form of anonymous rounding surveys for parents with a preliminary explanation of the questions asked. The questions included etiological factors for the occurrence of orthodontic anomalies (diseases in pregnancy, childbirth, breastfeeding, supplementation and feeding, type of pacifier, position of the bottle when eating, bad habits, position when sleeping, position of arms when sleeping in relation to the jaw, pillow height, mouth breathing, orthodontic anomalies in parents). Results: Results indicate the following etiological factors as the most common: supplementary feeding and bottle feeding (in 41.74% of cases), breastfeeding from 0 to 6 months (40.87% of respondents) and mouth breathing (in 24.35% of children). In the examination of the total risk for orthodontic anomalies, low-risk was found in 95.65% of cases, medium-risk in 4.35% (in Kisac 9.38%, in Kać 2.94%, in Veternik 4.35%, in Futog 0% of children), while there were no high-risk respondents. Conclusion: Preventive measures should be aimed at educating mothers about the need and benefits of a natural way of breastfeeding and of using a spoon for supplementation and feeding.","PeriodicalId":39229,"journal":{"name":"Acta Stomatologica Naissi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71202251","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}

Method: The current article describes a rare occurrence of cement-ossifying fibroma affecting maxilla in a 44 year old female patient. Clinically, the lesion was painless and slow growing in nature. Computed tomography revealed a hypodense area in the right posterior maxilla measuring 19.07mm X 27.11mm. The lesion was surgically resected under general anesthesia and it was histopathologically confirmed to be cemento-ossifying fibroma. Results: Total enucleation/ resection of the osseous lesion must be timely ensured to prevent recurrence and also to achieve good prognosis which was done in the described case report. No recurrence was reported in the present case which had a follow up for 24 months.

Pollution is registered all the times, as well as after prosthetic treatment. BIOA created during prosthetic workcontains various bacteria, fungi and viruses from the patient's oral cavity. These microorganisms pose a real hazard to health workers and are a potential risk for infection. The most common pathogens include influenza viruses, herpes viruses, as well as pathogenic streptococci and staphylococci. Infectious diseases, biosynosis, acute toxic reactions, allergies, atopic diseases, conjunctivitis, contact dermatitis, infections of the respiratory system, and even some types of cancer, are possible manifestations of side effects of BIOA. Conclusion:BIOA poses a potential danger to contamination of air, work surfaces and objects in dental offices.
