Eating behaviour in childhood has been implicated in the development of dental caries and further affecting the body mass index of the child. The aim was to assess the Problematic Eating Behaviour (PEB) and its association with dental caries status of the child. Material and Methods: Parents of 150 children between 3-8 years of age were divided into 2 groups, Group A (3-5 years) and Group B (6-8 years). The parents completed the Children’s Eating Behaviour Questionnaire (CEBQ) & the child’s dental caries status was recorded. The collected data was subjected to statistical analysis using unpaired t test & Pearson’s correlation coefficient test. Results: The results showed that the dental caries status was significantly higher in younger age group (3-5 years) than older age group (6-8 years). Further evaluating the PEB using CEBQ, there was no significant relation found between PEB and dental caries in younger age group of children (3-5 years), but in the older age group (6-8 years) the Factor 4 Desire to Drink (p=0,274) and Factor 5 Satiety Responsiveness (p=0,291) were significantly associated to the dental caries. Conclusions: Eating behaviour can contribute to the development of caries and this has been successfully studied with the use of CEBQ in the present study.","PeriodicalId":161469,"journal":{"name":"Balkan Journal of Dental Medicine","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131317769","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 paper was to evaluate the oral health, oral hygiene awareness and assess the degree of contamination of toothbrushes among students attending Secondary Medical School. Material and Methods: Sixty students (32 boys, 28 girls; mean age ≅ 15,7±2,1) attending highschool were randomly selected for this study. Each student included in the study filled out a questionnaire regarding his/her life habits and oral hygiene. Clinical examinations were initiated in order to determine the DMFT, as well as the CIP, CIT, CIA and CPITN indexes, based of which the assessment of oral health status was performed. One stack of fiber was collected from each toothbrush used by the participantes in the study, and than prepared for further microbiological sampling. Results: Only 11% of the students had the awareness of potential sources of toothbrushes contamination. The average value of DMFT was 3,2 (%D = 22,5; %M = 4,96; %F = 72,5). A statistically significant difference in comparison of the CPITN index and subjects’ response to the professional plague removal in the last 12 months was identified (χ2 = 13,55; p= 0,033). Staphylococcus aureus, Streptococcus mutans, Micrococcus species and Streptococcus salivarius were most commonly present microorganisms. In most cases, G-positive bacilli or cocci were isolated, while the presence of Candidae albicans was identified in four samples. Conclusions: Raising the awareness of dental hygiene through the oral health education may improve better plaque control and subsequently the oral health. Handson training how to maintain the oral hygiene are not expensive and more over they are easy to be organized can be useful in oral heath promotion.","PeriodicalId":161469,"journal":{"name":"Balkan Journal of Dental Medicine","volume":"115 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134092368","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}

It has a complex composition with a wide range of effects, including antibacterial, antiviral, antifungal, antiflogistic, antioxidant, hepatoprotective, carcinostatic and immunomodulatory properties. It is often applied in the treatment of diseases involving the oral cavity and gums. The aim of this paper is to describe the therapeutic properties of propolis, chemical composition and its application in the oral cavity. Literature and systematic information on the composition and the effects of propolis on health were collected, with particular reference to the use in the treatment of oral cavity diseases. The chemical composition of propolis is very complex. The health impact depends on the biologically active components it contains. A particularly important application is in the treatment of diseases of the oral cavity. Studies show that propolis can help prevent dental caries and control gingivitis and plaque. It reduces halithosis (bad breath) and symptoms of periodontosis. It is also effective in fighting viruses. It can have significant application in orthodontics and restorative dentistry. A wide range of effects allows the multiple uses of propolis-based products. Recent research has been increasingly focused on diseases of the oral cavity. The development of novel propolis-based pharmaceutical forms could significantly reduce the use of antibiotics in conventional treatment of diseases of the oral cavity.","PeriodicalId":161469,"journal":{"name":"Balkan Journal of Dental Medicine","volume":"164 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114003355","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}

None of the participants had previous experience in rotary instrumentation. The periapical radiographs were taken with the use of the paralleling technique for standardization and were collected and evaluated by the investigator. After the root canal treatment was performed the students completed a questionnaire in order to evaluate their training on rotary instrumentation.Results: The overall incidence of instrument separation, apical perforation, root perforation, straightening and ledges was 0.8%, 4.4%, 2.3%, 5.5% and 29% respectively on root canal level. Ledges were detected more often in mandibular mesiobuccal canals. The frequency of root canals with an ‘acceptable’ filling was 68.4%, while overfilled and underfilled canals were found to be 8.6% and 16.2% respectively. The response rate was high (94.9%), 35% of the participants encountered no difficulty in the use of rotary instrumentation and 98.2% would use it again.Conclusions: The incidence of procedural errors was considerably low and the technical quality of the filled root canals was superior to that of similar studies.

An online base Medline was searched to determine relevant papers, using the combination of the following terms: “asthma”, “cystic fibrosis”, “caries”, “dental erosion”, and “oral health”. Oral health problems in children with chronic respiratory diseases (CRD) may be influenced by natural course of the disease, pharmacotherapy (inhalation therapy with bronchodilators and inhaled corticosteroids in asthmatic patients, systemic antibiotics and pancreatic enzyme replacement therapy in CF patients), medication administration technique and nutritional habits. Children with CRD may have higher prevalence of oral diseases. Patients and their parents, but also general paediatricians and pulmonologists, should be aware of importance of good oral health. Dental practitioners should be more informed about risk factors and specificities of oral health in these patients.
