The Serbian version of CFSS-DS questionnaire is reliable and valid psychometric instrument for evaluation of dental fear in Serbian children. Dental anxiety negatively affects dental attendance and oral health of the examined schoolchildren.
The children with skeletal class III have significantly shorter maxilla than those with skeletal class I.
There were no significant differences in the parameter values on the cranial base between the groups. There was a significant correlation of the main angle of the cranial base with the angles of sagital position of the jaws in the group 1 only.
Introduction. Dental caries and gingivitis are common in school children although they can be prevented through the health education and application of preventive measures. The aim of this study was to determine the prevalence of caries, gingivitis and orthodontic irregularities in school children and to assess the efficacy of health education program in relation to the plaque and gingivitis control as well as caries treatment. Material and Methods. This study included 56 second grade students with early mixed dentition and 56 seventh grade students with permanent dentition, from elementary school “Borislav Petrov Braca” in Pancevo. DMFT/dmft index, Plaque index (PI) according to Sillness-Löe, and the prevalence of gingivitis and orthodontic anomalies were determined by clinical examination. The Interventional Program included oral hygiene education and the application of prophylactic measures. At one and six months follow-ups, PI, gingival health and changes in DMFT/dmft structure were reexamined. Results. Gingivitis was recorded in 78.56% of II and 50% of VII grade students. In the II grade students, mean DMFT was 1.36±1.41, and dmft 5.07±2.66. In the VII grade students mean DMFT was 4.36±3.34. The most common orthodontic anomalies were narrow maxilla, deep bite and distal bite. After six months of conducting the Program, reduction of gingivitis and number of carious teeth in DMFT/dmft structure as well as oral hygiene improvement were achieved in both age groups. Conclusion. Oral hygiene, dental status and the prevalence of orthodontic anomalies in school children indicate the necessity to intensify preventive measures. Health education programs contribute to improvement of oral health and increase motivation for self-care in children
Background/Aim. A period of adolescence is characterized by turbulent emotional, physical and physiological changes. There are numerous risk factors that may endanger the oral health of adolescents as the influence of parents reduces whilst the influence of the environment and peers increases. Therefore, the main aim of the study was to determine the behavior of adolescents concerning oral health, using a new statistical method -artificial intelligence algorithms. Methods.In the first part of the survey, data on the behavior of adolescents related to oral health were collected. HU DBI (Hiroshima University Dental Behavioral Inventory) questionnaire was used, additionally expanded with three questions. The second part of the study included clinical examination. The research was conducted at the Faculty of Dentistry in Pancevo. The first and second grade students were selected for the observation unit. The total sample consisted of 374 students (128 males and 246 females). We applied special programming language called Python for parsing data, creating a database in digital form, processing data by standard statistical methods and through the SVD (Singular Value Decomposition) method.Results. The artificial intelligence algorithms clustered the respondents in two groups, based on their responses from the HU DBI questionnaire. Thus, the quality of the method and the need for analysis of this type in dental studies are demonstrated and proven.Conclusion. Based on the results obtained through artificial intelligence algorithms, we could conclude that respondents should be rather clustered into characteristic groups and analyzed, than to be divided and observed according to sex, as it is intuitive division. Apstrakt Uvod/Cilј. Period adolescencije karakterišu burne emocionalne, fizičke i fiziološke promene. Javlјaju se brojni faktori rizika koji mogu ugroziti oralno zdravlјe adolescenata jer se uticaj roditelјa smanjuje, a raste uticaj okoline i vršnjaka. Sledstveno, glavni cilј istraživanja bio je da se utvrdi ponašanje adolescenata u vezi oralnog zdravlјa, pri čemu je primenjena nova statistička metodaalgoritmi veštačke inteligencije. 4 Metod. U prvom delu istraživanja, prikuplјeni su podaci o ponašanju adolescenata u vezi sa oralnim zdravlјem. Korišćen je HU DBI upitnik Univerziteta u Hirošimi (Hiroshima University Dental Behavioral Inventory), koji je proširen sa tri pitanja. Drugi deo istraživanja obuhvatio je klinički pregled. Istraživanje je sprovedeno na Stomatološkom fakultetu u Pančevu. Za jedinicu posmatranja izabrani su učenici prvog i drugog razreda srednje škole. Veličina ukupnog uzorka bila je 374 ispitanika (128 ispitanika muškog pola i 246 ispitanika ženskog pola). Za analizu podataka, pravlјenje baze podataka u digitalnoj formi, obradu podataka standardnim statističkim metodama i SVD metodom (Singular Value Decomposition -dekompozicija na singularne vrednosti), korišćen je Piton (Python) program programskog jezika.Rezultati. Algoritmi veštačke inteligencije klasterifikovali su ispitanike u dve grupe, ...
