Background An association between insufficient or irregular oral hygiene with the occurrence of dental caries, gingival/periodontal diseases, and consequently general diseases has been established. The null hypothesis that there is no difference in the oral health status among students in a preclinical medical program and those who went through a clinical medical program was tested. The main objective of the study was to analyze oral health risk factors (oral hygiene practices, attitudes, and behavior) as well as their impact on oral health by using convenience sampling. Material/Methods We investigated risk factors for oral health conditions by examining oral hygiene practices, attitudes, and behaviors among the students in the medical program of the University of Niš, collecting data using questionnaires. The study included 396 students of medicine, dentistry, pharmacy, and vocational studies. Participants filled out the anonymous questionnaire. Results In both groups, parents were mostly employed, with the representation of employed fathers significantly higher in student group 1 ( P <0.05), which is also the only statistically significant difference between the groups. In terms of oral hygiene practices, students were most often trained by parents (68.69%). A very high percentage of students brushed their teeth every day (97.22%), and 54.55% did this twice a day. Of the total number of students, 78.28% thought that it was necessary to use interdental brushes/floss/toothpick. The duration of teeth cleaning was 3 minutes in 39.39%, whereas 55.30% thought that it should be longer than 3 minutes. The most common brushing movements were combined movements and were used by 60.35% of all students. Of all students, 253 (63.89%) never smoked, 182 (49.96%) regularly went to the dentist, and 141 (35.61%) visited the dentist 6 months ago. The majority of students, 265 (66.92%), obtained the greatest amount of information about oral and tooth care from their dentist, which was the case in both age groups. Conclusions This study highlights oral health risk factors among students at the University of Niš. It is essential to determine their oral health knowledge, as it is of great significance both to patients and to students. Also, these students will be the major providers of health services and will be responsible for public oral health promotion. It could help in reformation of the oral health education program. The results of this research indicate that it is necessary to educate preclinical students to solve oral health issues.

SažetakUvod:Tretman bolesnika koji boluju od raka, u smislu hemoterapije i radioterapije, značajno je evoluirao od svog začetka. Obe terapije, naročito ako se koriste u kombinaciji, imaju veoma ozbiljan potencijal da dovedu do neželjenih efekata, koji narušavaju kvalitet života i potencijalno povećavaju mortalitet bolesnika obolelih od raka. Cilj rada:U ovom radu opisan je uticaj radioterapije i hemoterapije na oralna tkiva. Oralne komplikacije koje se posledično javljaju mogu se svrstati u sledeće kategorije: mukozsitis, kserostomija, gljivične, virusne i bakterijske infekcije, disgeuzija, disfagija, profuzno krvarenje, osteonekroza i mišićni trizmus. Zaključak:Budući da je potreban širok spektar preventivnih i kurativnih mera, pojavljuje se potreba za sastavljanjem posebnih timova za brigu o bolesnicima pre, tokom i nakon radioterapije i hemoterapije. Takav onkološki tim trebalo bi imati doktora stomatologije, specijalistu oralne medicine kao aktivnog člana. AbstractIntroduction: Cancer treatment, in terms of chemotherapy and radiotherapy has evolved significantly from its beginning. Both therapies, especially used in combination, had the potential to cause side effects, that potentially decrease in quality of life and lead to increased mortality rate in patients with cancer. The aim:of the study: The effects of radiotherapy and chemotherapy were described. The oral complications which consequently occurred could be classified into following categories: mucositis, oral dryness, fungal, viral and bacterial infections, disgeusia, disfagio, profuse bleeding, osteonecrosis and muscle trismus. Conclusion: Because of the wide range of preventive and curative measures, it is necessary to create a special team for caring of patients before, during and after radiotherapy and chemotherapy. In such case, dentist, oral medicine specialists should be an active member of oncology team.

Introduction: Under the concept of regenerative periodontal therapy, there are two approaches: the first is the passive regeneration conceptthat includes bone substituents and guided periodontal regeneration by using of biomembranes and the second concept of active regeneration that impliesthe use of growth factors. The aim of the passive regeneration, by using of bone matrix (bone substituens) has been stabilization and bone defects management, preventing epithelial tissue growth, as well as saving space for the new tissue regeneration. This concept implies the use of autogenous transplantats, xenografts, allografts, as well as alloplastic materials. The carriers for active tissue regeneration, growth factors -GF are biological mediators that regulate cellular processes and that is crucial for the tissue regeneration. Aim:Presentation ofmodern approaches to periodontal therapy thatare focused on the attachment regeneration and complete reconstruction of periodontal tissue. Conclusion: In the future, periodontal regenerative therapy with periodontalligament progenitor cells should encourage repopulation of the areas that have been affected by periodontal disease.
