Introduction. Poor oral health among elderly is most common dental problem nowadays, especially among the institutionalized persons.

Aim. To detect DMFT index among the institutionalized elderly.

Material and Method. Oral examination was made to make adequate evaluation. A total number of 70 subjects were evaluated. DMFT index has been detected only with dental mirror and probe, without using additional instruments and methods.

Results. Average value of DMFT index in our survey was 24.84 ± 4.56 (with Confidence interval from 23.77 to 25.89). M-component was dominant − 21.56 ± 7.79 (with Confidence interval from 15.74 to 23.38). D-component indicated by carious teeth and persistent roots had value 2.60 ± 3.54 (with Confidence interval from 1.77 to 3.42). Mean value of teeth with definitive fillings (F-component of DMFT index) was 0.34 ± 1.42 (with Confidence interval from 0.33 to 1.01).

Conclusion. DMFT index among the institutionalized elderly had one of the biggest values in the literature. M-component was dominant and indicator of the absence of many teeth. Therefore it is of great importance to prepare adequate protocol for oral health care among the institutionalized elderly.

examined under standardised conditions by a single qualified examiner; Plaque Index (PI), Modified Gingival Index (MGI) [ 10 ] and permanent decayed, missing, and filled teeth (DMFT) and primary dmft index were recorded. A questionnaire was distributed to all parents, including details regarding the children’s oral and dietary habits, and the parents’ level of education and oral habits [ 11 , 12 ]. All children and parents were educated and motivated with regard to the severity and prognosis of the dental aspects of haemophilia, and maintenance of good oral hygiene. The

results of our ab initio investigations with the particular emphasis put on the structural properties at high pressures and temperatures. We have used a LSDA+DMFT method [ 20 – 26 ] which merges the local spin density approximation (LSDA) with the dynamical mean-field theory (DMFT) [ 27 – 29 ] to account for the electronic correlations. This approach has been developed from the band structure and many-body communities have joined two of the most successful approaches of their respective fields. So far, LSDA+DMFT has been successfully employed to properly describe not


Objective: The study aimed to establish the mean DMFT of adults over the age of 20 years in Bulgaria. We also aimed to determine any association between demographic factors, such as age, gender, general health status etc, and dental caries.

Material and Methods: The study was conducted from 2006 to 2009. Data was collected from a randomly chosen representative sample of 1741 adults aged over 20 years, from 13 Bulgarian cities and villages. From these 1741 adults, 105 (6.03%) refused to complete the questionnaire. A total of 1636 (93.97%) were included in the survey, of which 766 (47%) lived in villages and small towns and 870 (53%) in the capital city Sofia and other cities. The average age of the sample was 39.6 years. 894 (54.6%) were male and 742 (45.4%) were female. Each participant completed a questionnaire about demographic and socio-demographic status. Afterwards, a clinical examination was carried out. Chi-square and one-way ANOVA were used to test for statistical significance of qualitative variables (p<0.05).

Results: For the whole study sample, mean DMFT was 17.8 (SD 7.98). There was a statistically significant association between DMFT and age. Women had higher DMFT values (18.6 ± 7.66)) than men (15.2 ± 7.91). There was a link between DMFT and general health too. People with excellent general health had DMFT 11.5 (SD 6.39), whereas people with bad general health had DMFT 21.4 (SD 8.16).

Conclusion: Mean DMFT score of adults in Bulgaria is 17.76 teeth. There is an association between some demographic factors and DMFT. Women, people with bad general health and older people have higher values of DMFT and need more care from dental health services.


Introduction. Dental caries is a serious problem affecting numerous populations around the world. During the last decade, there was a significant increase of its prevalence in many countries. Hence, the dental epidemiological status requires some further analysis.

Aim. This study was designed to assess the prevalence of dental caries among adults of various age and gender groups treated by dental students of English Division at the Chair and Department of Conservative Dentistry and Endodontics of the Medical University of Lublin.

Material and methods. The authors collected and analyzed the dental history of patients who had been treated at the university dental clinic in Lublin throughout 2013 and 2014.

Results and Conclusions. The mean DMFT index of examined group of patients increases with age and it tends to be higher in women than men. Class I dental caries according to Black’s classification was the most prevalent, followed by class II, class III, class V and class IV. Caries tends to affect molars and premolars most commonly. In addition, these teeth were most likely to be extracted and restored.


Background: Despite the availability of a variety of preventive and treatment modalities, caries in the early childhood remains a serious and prevalent disease worldwide.

The aim of this study was to assess the prevalence of early childhood caries (ECC) among 24 to 71-month old children who attended the Center for preschool education Banja Luka, Republic of Srpska, Bosnia and Herzegovina.

Material and Methods: This was a cross-sectional study. The whole sample included 297 children of both genders. Caries status of each child was recorded using the dmft index according to the WHO criteria.

Results: Two hundred ninety-seven children (138 girls and 159 boys) 24 to 71-month old were examined. The overall prevalence of dental caries was 64.65%. Only 23 (7.74%) children had their teeth restored.

Conclusions: ECC prevalence among 24 to 71-month old children who attended the Center for pre-school education in Banja Luka is very high, but the problem is even greater because most of those caries lesions are untreated.

classified to have carries [decayed, missing, filled-teeth (DMFT)=5.6] according to the World Health Organization (WHO) criteria, and 20 of them (aged between 19 to 26, mean age 21.95 ± 2.2) were caries- free (DMFT=0). Inclusion criteria for subjects with caries and without caries were as follows; no oral complains, good oral hygiene, absence of smoking and drinking habits, no systemic diseases, no drug abuse. Exclusion criteria was unwillingness to participate in the study. The subjects signed an informed consent form to participate in this study. Clinical Examination One


The prevalence of early childhood caries and its level varies. The present study was to establish the trends in dental caries and the impact of behavioural changes on the prevalence of caries in three-yearolds in Poland within a fifteen-year period. The results of a cross sectional survey carried out on 3439 three-year-olds in 2002, 2009, and 2017 using WHO criteria for dental caries (dmft, dmft=0, dmft≥4) and the results of a questionnaire filled by their parents with data on sociodemographics, oral hygiene and dietary habits, especially their sugar intake, were assessed. The dmft/dmfs index is applied to the primary dentition and is expressed as the total number of teeth/surfaces that are decayed, missing, or filled. The Cochran-Armitage test for trend was used to assess the fraction changes in time. The Pearson correlation coefficient was used to assess the changes in dmft trends and the correlations between behavioural changes, awareness levels, and the prevalence of caries. Within the fifteen-year period minimal changes in the prevalence of early childhood caries (15% down), dmft≥4 (11.4% down) and a lower dmft (36% down) were accompanied by a better parent awareness about the causes of caries and better oral hygiene routines. Sugary beverages were no longer drank at least once a day, however sweetened milk, cake, doughnuts, and sweet rolls were consumed more often. Being female, living in an urban area, having parents more aware about caries, consuming sugary beverages less frequently, brushing teeth twice a day, and using a fluoride toothpaste promoted lower early childhood caries. Gradually healthier teeth are linked to an increased awareness of the parents and healthier routines. A too frequent exposure to sugar promotes early childhood caries. Should the changes of dietary habits be insufficient, brushing teeth with fluoride toothpaste becomes crucial.
