The study included a total of 699 students of different study\u0000 fields who underwent a dental examination, with 530 of them agreeing to an\u0000 assisted survey and 275 forgoing a periodontal assessment. The survey\u0000 consisted of six sections - basic information, socio-demographic data, oral\u0000 healthcare use and habits, risk factors, OH self-assessment and OHRQoL.\u0000 Clinical assessment was performed using the Decayed, Missing, Filled teeth\u0000 (DMFT) index; Gingival Index; Clinical Attachment Level; Community\u0000 Periodontal Index, and Plaque index.

Its\u0000 buffer capacity helps neutralise acidic products from food, drinks and\u0000 dental plaque. Saliva composition, quantitative and qualitative properties,\u0000 such as acidity, are associated with the occurrence of dental caries,\u0000 non-carious lesions and periodontitis. The aim of the study was to examine\u0000 the change in salivary acidity after taking carbonated mineral water and\u0000 sugar-sweetened carbonated soda in subjects aged 18 to 25 years. Materials\u0000 and method. The study research was conducted at the Dentistry Clinic of\u0000 Vojvodina on 30 adult subjects. Salivary acidity was measured with a digital\u0000 pH meter before, and 5, 10 and 20 minutes after taking 200 ml of carbonated\u0000 mineral water and 200 ml of sugar-sweetened carbonated soda. The obtained\u0000 results were statistically processed by mixed, combined analysis of\u0000 variance. Results. Consumption of carbonated mineral water and\u0000 sugar-sweetened carbonated soda led to a change in salivary acidity in the\u0000 examined time intervals. Carbonated mineral water reduced the salivary\u0000 acidity, and after 20 minutes the acidity recovers reaching levels close to\u0000 the initial pH value. After taking sugar-sweetened carbonated soda, the\u0000 salivary pH value dropped. It reached the lowest mean value 5 and 10 minutes\u0000 after taking the beverage, and then increased slightly without reaching the\u0000 initial value. In some subjects, the minimum value of the salivary pH\u0000 obtained was below the value considered critical for the occurrence of\u0000 enamel and dentin demineralisation. Conclusion. Carbonated mineral water and\u0000 sugar-sweetened carbonated soda affected the salivary pH value within a\u0000 period of 20 minutes after consumption. Consuming sugar-sweetened carbonated\u0000 soda can have adverse effects on oral health.","PeriodicalId":180624,"journal":{"name":"Serbian Dental Journal","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115055949","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 aim of this informative paper is to show the importance and\u0000 key role of atomic force microscopy, on one hand, in quantitative\u0000 determination of the physicochemical changes on the surfaces of dental\u0000 materials due to their exposure to acids and, on the other hand, in\u0000 quantification of changes in the physicochemical properties of the surfaces\u0000 of dental alloys after their processing and the consequences of the\u0000 processing itself on the quality and applicability of the same.

The width of the\u0000 mandibular alveolar ridge in the inter-canine region was 2 mm.

A retrospective analysis of data from the National\u0000 Health Account of the Institute of Public Health of Serbia, the regulations\u0000 of the Republic Health Insurance Fund, reports of the Ministry of Health as\u0000 well as laws and regulations related to the health sector was performed.\u0000 Results. The results of the analysis showed that the State health sector\u0000 represented the foundation of the health system in the Republic of Serbia in\u0000 the observed period. Of the total health financing, it was estimated that\u0000 about sixty percent were public financing schemes, and about forty percent\u0000 belonged to private schemes, with a large part of private schemes being\u0000 out-of-pocket payments. Conclusion. The general conclusion of the analysis\u0000 is that in the observed period, within the framework of the reform changes,\u0000 Serbia had a good system of exemption from participation, but that\u0000 out-of-pocket payments for certain health services and corrupt payments\u0000 represented a barrier to health care.","PeriodicalId":180624,"journal":{"name":"Serbian Dental Journal","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130243178","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}
