Dental Students’ Experiences during the COVID‐19 Pandemic — A Cross‐Sectional Study from Norway

The purpose of this cross-sectional study was to map dental students’ experience of the study situation throughout the pandemic. All clinical dental students (year 3 to 5) at the Faculty of Medicine, Department of Clinical Dentistry (IKO), University of Bergen (UiB), Norway, were invited. Participation was anonymous and voluntary, and the response rate was 63%. Questions regarding stress-related factors were divided into three categories. In the category «Stressors/learning», a statistically significant difference was observed between both the genders (p = 0.001) and years of study (p = 0.028). Statistically significant differences between the genders were also observed in the category «Stressors/infection» (p = 0.008). Women were significantly more stressed due to lack of clinical skills (p = 0.048), not receiving as good theoretical teaching as before the pandemic (p = 0.016), and uncertain issues around the exams (p = 0.000). Fourth year students were significantly more stressed due to lack of clinical skills (p = 0.012), for not passing the clinic/skills courses due to lack of study progression (p = 0.005), and worries about not being a good enough dentist after graduation (p = 0.002). In conclusion, the pandemic had a major impact on dental students. The most prominent stressors in relation to the study situation were experienced by students from the fourth year and female students. Clinical and theoretical learning outcomes among students were regarded as worse than before the pandemic. The students preferred in presence lectures, but experienced digital asynchronous video lectures as a good alternative. The pandemic negatively affected the students’ social life. Dental schools should be aware that students have been exposed to increased distress and burden through the pandemic and should provide support for those in need.publishedVersio

Quality of life measured by OHIP-14 and GOHAI in elderly people from Bialystok, north-east Poland

BACKGROUND: The Oral Health Impact Profile-14 (OHIP-14) and the Geriatric/General Oral Health Assessment Index (GOHAI) have never been compared for a group of the same subjects in the Polish population. The aim of the study was to compare the OHIP-14 and GOHAI measures. METHODS: 178 independently living people over the age of 55 were included in the study. The GOHAI and OHIP-14 measures were used. Other variables included age, gender, self-ratings of oral general health, education, number of missing teeth, chewing problems and dry mouth. RESULTS: The mean age of respondents was 70.8 years. The internal reliability (Cronbach’s alpha) showed a high internal consistency for both measures. Spearman’s rank correlation coefficient between the GOHAI and OHIP-14 scores was 0.81. Using the additive method of creating scores, 1.1% of respondents had the GOHAI score of zero, indicating no impact from oral conditions, while 13.5% of them had an OHIP-14 score of zero. Dental status, partial dentures, chewing problems, dry mouth and self-rated oral health were significantly associated with the results of the GOHAI and the OHIP-14 (Kruskal–Wallis test, Mann–Whitney U test). The numbers of preserved and missing teeth significantly correlated with the GOHAI and the OHIP-14, while DMF was significantly associated with the GOHAI only. 6 individuals with discrepant results were revealed. After the exclusion of the abovementioned patients, the internal reliability (Cronbach’s alpha) still showed a high internal consistency, and the correlation between the GOHAI and OHIP-14 scores using Spearman’s rank-correlation coefficient increased to 0.87. This phenomenon was identified as a “fatigue effect”. CONCLUSIONS: There was a strong correlation between the GOHAI and the OHIP-14. Both instruments demonstrated good discriminant properties and helped capture the respondents’ oral health problems. The questionnaires should be randomly distributed to avoid the influence of “fatigue effect” on the results of a comparison of different measures

Polish School Nurses’ Attitudes and Knowledge towards Topical Fluoride Treatment

Cilj: Željelo se procijeniti mišljenje školskih medicinskih sestara u Poljskoj o topikalnoj primjeni fluorida te njihovo znanje o sigurnosti toga kemijskog spoja. Metoda: U presječnom istraživanju s pomoću anketnog upitnika sudjelovale su 164 školske medicinske sestre. Anketa je obuhvaćala raniju izobrazbu o prevenciji karijesa, mjere poduzete u školama kako bi se prevenirao karijes, suradnju s doktorima dentalne medicine, mišljenje o topikalnoj primjeni fluorida te znanja sestara o njihovoj sigurnosti. Rezultati: Oralno zdravlje bilo je uvršteno u dužnost 93,9 % sestara, a 81,7 % provodilo je lokalnu primjenu fluorida. U izobrazbi o oralnoj problematici nikada nije sudjelovalo njih 52,1 %. Sestre iz gradova češće su sudjelovale i održavale predavanja o prevenciji karijesa i o fluoridima od svojih kolegica u manjim gradovima (p = 0,033 i 0,021 – hi-kvadrat test). Sestre su imale pozitivno stajalište o učinkovitosti i sigurnosti topikalne primjene fluorida. Samo je polovina ispitanica znala za moguću toksičnu dozu, a jedna petina nije znala kolika je koncentracija fluora u gelu. Ta su znanja bila statistički važna, ovisno o razini izobrazbe pojedine sestre (p = 0,019 – Kruskal-Wallisov test). One s niskom razinom znanja nisu bile svjesne moguće štetnosti fluorida te su imale negativno stajalište o učinkovitosti programa fluoridacije u školama. Zaključak: Školske medicinske sestre u Poljskoj imale su pozitivno mišljenje o topikalnoj primjeni fluorida. No, ima manjkavosti u njihovu znanju pa im je potrebna institucionalizirana izobrazba.Aim: The aim of this study was to evaluate the Polish school nurses’ opinion on the topical fluoride treatment and their knowledge about fluoride safety. Material and methods: A cross-sectional study with the use of a self-administered questionnaire was conducted on 164 school nurses. The questionnaire concerned previous training in caries prevention, action taken at schools with regard to caries prevention, cooperation with dentists, opinion on the topical fluoride application program and nurses’ knowledge about fluoride safety. Results: 93.9% of nurses included oral health in their duties and 81.7% accomplished the topical fluoride treatment. 52.1% never attended any training concerning dental issues. Nurses from cities and villages more often than those from towns provided lectures on caries prevention and fluoride topical applications (respectively p= 0.033 and p=0.021, chi2 test). The nurses had a positive opinion on the effectiveness and safety of topical fluoride application. Only a half of respondents knew the fluoride probable toxic dose and one fifth of them did not know the concentration of fluoride in gel. The knowledge was statistically dependent on the level of nurses’ education (p=0.019, Kruskal-Wallis test). Nurses with a low level of knowledge were not aware of a potential harm effect of fluoride and they had negative opinion about the effectiveness of fluoride program at school. Conclusion: Polish school nurses had a positive opinion on topical fluoride treatment. However, there are gaps in their knowledge and the institutional training is needed

Smoking Prevalence, Attitudes and Behavior among Dental Students in Poland and Italy

The aim of the study was to perform preliminary research to compare the smoking prevalence, attitudes and behavior between dentistry students in two universities in Europe using the standardized Global Health Professions Student Survey (GHPSS) questionnaire. This was cross-sectional carried out among dentistry students from the Medical University in Bialystok, Poland and Sapienza University of Rome, Italy. There were 582 participants; 282 were Italians, 202 were smokers and 42% were Italians. The response rate was 79.9% of Italian students and 79.6% of Polish students. The prevalence of smoking was significantly higher among Italian students (42% vs. 28.0%). Attitudes and behaviour of smokers and non-smokers differed statistically. Polish and Italian dental students presented statistically different behavior regarding the time to smoke the first cigarette, the willingness to stop smoking and trying to stop smoking in the last year. The multiple logistic regression analysis revealed that two independent variables, exposure to second-hand smoke (SHS) both at home and in public places (OR = 3.26 and OR = 5.9, respectively), showed a significantly higher occurrence of smoking. There is a high use of tobacco among dental students, which is particularly high in Italian dental students. Students realizes the positive perception of their own tobacco counsellor role in a dental setting. Dental students should be role models to their peers and patients.publishedVersio

Targeted proteomics in a population-based study identifies serum PECAM-1 and TRIM21 as inflammation markers for periodontitis

Objectives Periodontitis (PD) can cause systematic inflammation and is associated with various metabolic processes in the body. However, robust serum markers for these relationships are still lacking. This study aims to identify novel circulating inflammation-related proteins associated with PD using targeted proteomics. Materials and methods We used population-based, cross-sectional data from 619 participants of the Polish Longitudinal University Study (Bialystok PLUS). Mean pocket probing depth (mPPD) and proportion of bleeding on probing (pBOP) served as exposure variables. Fifty-two inflammation-related proteins were measured using the Olink Target 96 Cardiovascular III and the Olink Target 96 Immune Response panels. Associations between periodontal measures and proteins were tested using covariate-adjusted linear regression models. Results At a false discovery rate of < 0.05, we identified associations of mPPD and pBOP with platelet-endothelial cell adhesion molecule-1 (PECAM-1) and tripartite motif–containing protein 21 (TRIM21). Conclusion This study revealed novel associations between PD and serum levels of PECAM-1 and TRIM21. Our results suggest that these proteins might be affected by molecular processes that take place in the inflamed periodontium. Clinical relevance Novel associations of PECAM-1 and TRIM21 with PD indicate promising serum markers for understanding the disease’s pathophysiological processes and call for further biomedical investigations

The role of Polish school nurses in the oral health promotion for 7-19 year-old children and adolescents

Purpose The assessment of the role of school nurses in the oral health education and counselling of children and adolescents aged 7–19 years. Methods A self-administered questionnaire was used to evaluate nurses’ practice in oral health education, previous training in caries prevention, collaboration with a dentist and self-assessment of knowledge. Data were analysed with the Chi square test. Results The study group consisted of 140 Polish school nurses. Respondents declared the following activities: dietary counselling (99.2%), oral hygiene education (92.8%), NHS-funded supervised fluoride prophylaxis (82.8%), and caries screenings (4.3%). 47.1% participated in training on caries prevention, 25.7% had a collaboration with a dentist. Nurses from schools located in towns less frequently provided oral hygiene education (p < 0.005) and dietary counselling, but more often had a collaboration with a dentist (p < 0.05). The youngest nurses were more confident about their knowledge (p < 0.05). There was an association between participation in training on caries prevention and positive opinion on a school-based fluoride prophylaxis (p < 0.01). Nurses who did not include dental topics in their practice worked mainly with pupils older than 15 years, had shorter experience (p < 0.05), secondary education, worked in urban areas and had no training on dental problems (p < 0.01). Conclusion Polish school nurses have potentially crucial roles in improving the oral health status in pupils through oral hygiene education, dietary counselling and fluoride prophylaxis included in their duties

Application of Cluster Analysis in Assessment of Dietary Habits of Secondary School Students

Maintenance of proper health and prevention of diseases of civilization are now significant public health problems. Nutrition is an important factor in the development of youth, as well as the current and future state of health. The aim of the study was to show the benefits of the application of cluster analysis to assess the dietary habits of high school students. The survey was carried out on 1,631 eighteen-year-old students in seven randomly selected secondary schools in Bialystok using a self-prepared anonymous questionnaire. An evaluation of the time of day meals were eaten and the number of meals consumed was made for the surveyed students. The cluster analysis allowed distinguishing characteristic structures of dietary habits in the observed population. Four clusters were identified, which were characterized by relative internal homogeneity and substantial variation in terms of the number of meals during the day and the time of their consumption. The most important characteristics of cluster 1 were cumulated food ration in 2 or 3 meals and long intervals between meals. Cluster 2 was characterized by eating the recommended number of 4 or 5 meals a day. In the 3rd cluster, students ate 3 meals a day with large intervals between them, and in the 4th they had four meals a day while maintaining proper intervals between them. In all clusters dietary mistakes occurred, but most of them were related to clusters 1 and 3. Cluster analysis allowed for the identification of major flaws in nutrition, which may include irregular eating and skipping meals, and indicated possible connections between eating patterns and disturbances of body weight in the examined population

The Use of Joinpoint Regression Analysis in the Mortality Study of Developmental Age Population in the Podlaskie Voivodeship, 2003–2012

The youngest population in society is recognized as that at the healthiest stage of life but is burdened by the occurrence of premature death that should be avoidable. There is a need to use adequate statistical methods in assessing the health status of the population of developmental age. The aim of the study was to analyze trends of mortality in children and adolescents by age and gender in the Podlaskie Voivodeship in the years 2003-2012 by joinpoint regression and to identify the causes of mortality. The mortality rate was analysed according to gender and the age groups: 0, 1-4, 5-9, 10-14 and 15-19 years in the Podlaskie Voivodeship. The data were obtained from the Central Statistical Office for the period 2003-2012. Differences in mortality levels between age and gender subgroups were obtained by the Wilcoxon signed-rank test. Join- point regression was used to analyze the trends in mortality. The nomenclature of ICD-10 was used to assess the causes of mortality of children and adolescents. In the Podlaskie Voivodeship in the years 2003-2012 in the 0-19-year-old age group, the highest proportion of deaths (42.4%) occurred during the first year of life. There were differences in mortality rates between boys (8.0/104) and girls (3.1/104) in the 15-19-year-old age group (p < 0.01), and also between the 1-14-year-old and 15-19-year-old age groups (p < 0.01), both among boys (2.1/104 vs. 8.0/104) and girls (1.5/104 vs. 3.1/104). Monotonous trends were shown regarding total mortality rates in infants. There was a drop in the mortality rate of infant girls (AAPC = 5.3%, p < 0.05) and boys (AAPC = 4.7%, p < 0.05). Changes in the direction of the total mortality rate trend were visible in the population of boys aged 1-14 years, in which, between 2003 and 2010, a significant reduction in mortality (AAPC = 9.5%) was observed, while in the years 2010-2012 the trend was not significant. No statistical evidence was found that mortality changed among girls in the 1-14-year-old and 15-19-year-old age groups. Deaths in infancy were due to perinatal conditions and congenital mal- formations. The main causes of mortality in the 1-19-year-old age group were external causes, mainly traffic accidents and intentional self-harm. Joinpoint regression indicated a uniform decrease of mortality in the years 2003-2012 except for boys from 1-14 years old, for whom the decreasing trend was for the years 2003-2010 with subsequent stabilization. The main problems are still infant deaths due to perinatal conditions, traffic accidents and intentional self-harm in boys in the 15-19-year-old age group
