Coeliac disease and its implications on the oral health of children: A systematic review.

AIM: Apart from various typical gastrointestinal symptoms, coeliac disease may have its clinical manifestations in the oral cavity which is the entrance of the gastrointestinal tract. METHODS: A systematic review of literature was performed using the following databases: Medline, Scopus, EBSCOhost and Cochrane Library for Systematic Review. INCLUSION CRITERIA: observational or experimental original studies published in English with full text available between January 2000 and December 2022, regarding children and adolescents under the age of 20. Risk of bias was determined with the use of Risk Of Bias In Non-randomised Studies of Exposure. RESULTS: Thirty-four studies were included in the review. The analysis confirmed a higher prevalence of numerous oral manifestations in coeliac disease concerning both hard and soft tissues. Our study found the prevalence of dental enamel defects to be at the level of 17.9%-83.5% (P value <0.047) and recurrent aphthous stomatitis of 8.3%-69% (P value <0.039). CONCLUSION: Oral manifestations may precede gastrointestinal symptoms. Patients presenting such manifestations should be screened for coeliac disease. The cooperation of gastroenterologists and dentists could lead to an increased detectability of coeliac disease.

The association of maternal smoking and other sociobehavioral factors with dental caries in toddlers: A cross-sectional study.

Background: Severe early childhood caries (S-ECC) is a form of dental caries in toddlers, which can strongly affect general health and quality of life. Studies on factors that can contribute to the development of caries immediately after tooth eruption are sparse. The aim of this study was to assess the role of sociobehavioural factors and pre- and postnatal exposure to tobacco smoke in the aetiology of dental caries in children up to 3 years old. Methods: A cross-sectional study was conducted between 2011 and 2017 to assess oral health and teething in urban children 0-4 years of age. The number of teeth and surfaces with white spot lesions (d1,2), as well as decayed (d), missing (m), and filled (f) teeth classified according to ICDAS II was evaluated in a dental office setting. d1,2dmft and d1,2dmfs were calculated. Severe early childhood caries was diagnosed for d1,2dmfs > 0. Parents completed a self-administered questionnaire on socioeconomic factors, maternal health, course of pregnancy, child's perinatal parameters, hygiene and dietary practices, as well as maternal smoking during and after pregnancy. Data on children aged 12-36 months were collected and analysed statistically using the t-test, Spearman rank correlations and Poisson regression. Significance level was set at 0.05. Results: Dental caries was found in 46% of 496 children aged 12-36 months. Mean d1,2dmft and d1,2dmfs were 2.62 ± 3.88 and 4.46 ± 8.42, respectively. Tobacco smoking during and after pregnancy was reported by 8.9% and 24.8% of women, respectively. Spearman's rank correlation analysis confirmed a relationship between S-ECC and parental education, maternal smoking, bottle feeding, avoiding springy foods, number of meals, and the age of tooth brushing initiation. Pre- and postnatal exposure to tobacco smoke increased the risk of S-ECC especially in children in age 19-24 months. Maternal smoking was correlated with the level of education and dietary practices. Conclusion: Our study confirmed that prenatal smoking is associated with increased risk of severe-early childhood caries (S-ECC) while the association with post-natal smoking is also evident, the increase in risk is not statistically clear. Both maternal smoking and the child's tooth decay are associated with poor parental education and other improper oral health behaviours. The positive impact of quitting smoking on the oral health in children should be part of anti-smoking advice.

Developmental enamel defects and their relationship with caries in adolescents aged 18 years.

Randomly selected 1,611 individuals aged 18 years formed a nationally representative sample from all provinces of Poland. Developmental defects of the enamel (DDE) and caries were assessed using the modified DDE index, molar incisor hypomineralisation (MIH) Treatment Need Index (MIH-TNI), FDI and WHO criteria by 22 trained and calibrated dentists. T-test was used for comparing group means. A simple and multiple logistic regression tests were used to assess the relationship between DDE and caries severity expressed as DMFT (p < 0.05). The prevalence of DDE was 13.7%. Demarcated opacities (DEO) were the most frequent (9.65%); 4% had diffuse opacities (DIO) and 1.5% had hypoplasia. MIH was diagnosed in 0.6% patients. The prevalence of caries was 93.2%, with mean DMFT of 6.50 ± 4.22. The DMFT value was 7.52 ± 4.77 in the group of patients with demarcated opacities (DEO); 7.85 ± 4.74 with diffuse opacities (DIO) and 7.56 ± 4.57 with enamel hypoplasia, respectively. There was a significant relationship between caries severity and DDE (p < 0.001), DEO (p = 0.001) and DIO (p = 0.038), and between DDE and DMFT index (p < 0.001). The results obtained in the study proved the significant relationship between DDE and DMFT in 18-year-olds, the assessment of which was the aim of the study.

Prevalence, Etiology, and Types of Dental Trauma in Self-Assessment of 18-Year-Olds in Poland.

The aim of the study is to determine the occurrence and etiology of traumatic dental injuries of permanent teeth and to evaluate the relationship between diagnosed injuries and selected socio-economic indicators. In total, 1741 students aged 18 years, representing all the regions of Poland, took part in the survey. Questionnaires for monitoring studies were prepared in accordance with the criteria of the World Health Organization. Among the respondents, tooth trauma was reported by 18% of adolescents. The most common trauma occurred during other activities (e.g., playing) (64%). The most common direct cause of injury was a fall (43%) or a collision with an object or another person (36%). Risk of injury was increased by a low level of parents' education and poor financial situation of the family. Playing sports is important in the etiology of injuries. The incidence of injuries was highest in school, demonstrating the need for school education in injury prevention and first aid. Occurrence of injuries, their causes, therapy, and post-traumatic complications were similar in respondents of both genders, which can be explained by secularization trends. Risk of injury was increased by parents' low level of education and poor economic status. The research demonstrates the need for universal education on treatment of dental injuries.

Vitamin D Supplementation, Characteristics of Mastication, and Parent-Supervised Toothbrushing as Crucial Factors in the Prevention of Caries in 12- to 36-Month-Old Children.

Severe early childhood caries (S-ECC), defined as any sign of smooth-surface caries in a child younger than three years of age, remains a serious health issue. The aim of this study was to indicate oral health behaviours related to S-ECC. The study surveyed parents (socio-economic and medical factors, oral health behaviours) and clinically examined children including non-cavitated d1,2/cavitated d ≥ 3 lesions. %S-ECC, and caries indices (d1,2 d ≥ 3 mft and d1,2 d ≥ 3 mfs) were calculated. Spearman's correlation and simple and multiple logistic regression were used to assess the relationships between various factors and S-ECC. A total of 496 children were examined. S-ECC occurred in 44.8%: d1,2 d ≥ 3 mft = 2.62 ± 3.88, d1,2 d ≥ 3 mfs = 4.46 ± 8.42. S-ECC was correlated with socio-economic factors, vitamin D supplementation, breastfeeding and using formula after the 18th month, and toothbrushing. Supplementation of vitamin D and toothbrushing tended to decrease the odds of S-ECC (OR = 0.49 (0.27−0.87); p = 0.016, OR = 0.46 (0.24−0.86) p = 0.015, respectively). Feeding exclusively with formula was observed to increase the odds of S-ECC (OR = 2.20 (1.29−3.76); p = 0.004). Consuming > three snacks daily (OR = 1.39 (0.97−1.98); p = 0.072) and the reluctance to eat resilient foods (OR = 1.63 (1.05−2.51); p = 0.028) were nullified by the confounding factors. Vitamin D supplementation, mastication of resilient food, breastfeeding in the first six months of a baby's life, and parent-supervised toothbrushing are factors in the prevention of caries in toddlers. Breast- and bottle-feeding after the 18th month of life, the reluctance to eat solids, lack of vitamin D supplementation, hygienic neglect, and delay in introducing oral health behaviours may contribute to the development of caries in toddlers.

Screening for SARS-CoV-2 Infection in Students at the Medical University of Warsaw, Poland Between November 15 and December 10, 2021 Using a Single Lateral Flow Test, the Panbio™ COVID-19 Ag Rapid Test.

BACKGROUND Education was significantly affected by the coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus. Online learning affects the quality of learning as well as the mental health status of students. Regular screening for COVID-19 may be crucial to provide practical classes during the pandemic. The present study aimed to analyze the usefulness of rapid antigen tests for on-campus COVID-19 screening in real-life conditions at a medical university in Poland. MATERIAL AND METHODS This screening study was carried out among students attending practical classes at the Medical University of Warsaw, Poland between November 15 and December 10, 2021, during which a series of rapid antigen tests (Panbio™ COVID-19 Ag Rapid Test Device, nasal) were performed by healthcare professionals (nurses). Out of 104 student groups selected for the study (n=1847 students), 423 individuals from 63 student groups were tested at least once (22.9% response rate). A total of 2295 samples were collected. RESULTS Among the participants, 3.4% (n=15) had positive test results. Out of 15 COVID-19 cases, 14 were vaccinated. At least 1 positive COVID-19 case was detected in 8 student groups. In 3 student groups, we observed ≥2 infections that occurred at intervals, which may suggest student-to-student SARS-CoV-2 transmission. CONCLUSIONS This study produced real-world data from a COVID-19 screening study and confirmed the usefulness of the rapid antigen test (Panbio™ COVID-19 Ag Rapid Test Device nasal) for on-campus COVID-19 screening prior to practical classes. Maintaining a high percentage of participants is crucial to ensuring the effectiveness of on-campus COVID-19 screening.

Premature Loss of Deciduous Teeth as a Symptom of Systemic Disease: A Narrative Literature Review.

BACKGROUND: Premature loss of primary teeth can occur as a consequence of dental trauma, neonatal tooth extraction, early childhood caries, or periodontal problems, or it can be a manifestation of systemic disease. This review aims to present systemic disorders that can lead to premature loss of deciduous teeth in children and to provide a comprehensive resource for clinical practice for both physicians and dentists. METHODS: This study is a narrative review of original studies and case reports published in English and Polish between 1957 and 2021 that was conducted by searching electronic scientific resources: PubMed, Google Scholar, Web of Science, and Science Direct. The schema of the qualification process is represented by a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). In total, 196 articles were identified; after provisional assessment of the titles and abstracts by two reviewers, 46 were found to be relevant to the topic, including 1 review, 16 original papers, and 27 case reports regarding systemic disease resulting in premature tooth loss. RESULTS: In this study, 16 systemic diseases were linked to premature primary tooth loss in children: Papillon-Lefèvre syndrome, mucocutaneous dyskeratosis, Coffin-Lowry syndrome, congenital adrenal hyperplasia, Langerhans cell histiocytosis, cherubism, hypophosphatasia, acatalasia, Chediak-Higashi syndrome, cyclic neutropenia, erythromelalgia, Down syndrome, Hajdu-Cheney syndrome, short bowel syndrome, leukocyte adhesion deficiency type 1 (LAD-1), and Wiedemann-Steiner syndrome (WSS).

Developmental Abnormalities of Teeth in Children With Nephrotic Syndrome.

INTRODUCTION: Treatment with glucocorticoids in children with nephrotic syndrome can be the cause of developmental disorders of the masticatory organ and bone or teeth abnormalities. The aim was to assess the frequency and type of dental abnormalities and the correlation of their occurrence with a dosage of glucocorticoids and treatment time in children with idiopathic nephrotic syndrome. METHODS: The study group consisted of 31 patients aged 5 to 17 diagnosed with idiopathic steroid-sensitive nephrotic syndrome and 33 overall healthy children. The studies included clinical evaluation of dentition, radiologic diagnostics, and statistical analysis. RESULTS: In the study group, 77.4% of patients were diagnosed with abnormalities in dental development. Tooth number disorders, presence of persistent deciduous teeth and impacted teeth, abnormal crown or root shape, developmental defects of enamel, pulp stones, and bone structure disorders were identified. Statistical analysis showed significant differences in the average treatment time of glucocorticoids in patients without and with tooth developmental abnormalities. CONCLUSIONS: Long-term use of glucocorticoids in children with nephrotic syndrome promotes the occurrence of developmental abnormalities of the teeth, calcification of the pulp, and disorders of bone tissue metabolism. For this reason, patients with steroid-sensitive nephrotic syndrome should be under the constant care of a dentist.

Knowledge and Attitude of Polish Dental Healthcare Professionals during the COVID-19 Pandemic.

OBJECTIVES: This study analyzed Polish dentists' knowledge of the SARS-CoV-2 virus and the main problems in their work during the early phase of the pandemic. METHODS: Dentists responded to an online anonymous survey consisting of 57 questions relating to socio-demographics, knowledge about COVID-19, and office procedures. The obtained data were analyzed using basic descriptive statistics, significance of dependencies and Chi square and Mann-Whitney tests; p < 0.05. RESULTS: Ultimately, responses from 730 dentists were included. The mean age was 43.62 ± 11.57. Almost 3/4 of the respondents followed the information on COVID-19. A total of 95.5% had knowledge about COVID-19. Genetic testing was the basic test according to 69.2%. Further, 56.0% were concerned about the pandemic, and 23.6% were significantly anxious. In addition, 42.1% considered a risk of infection with the SARS-CoV-2 in the workplace as very high. A total of 84.0% admitted patients performing a triage and using personal protective equipment (PPE). Further, 44.5% planned to become vaccinated. Continuing the work during the pandemic was strongly correlated with age, sector, and location and duration of work. CONCLUSIONS: Most Polish dentists follow the information on the COVID-19 protocol and have sufficient knowledge about COVID-19. Dentists are concerned and anxious about the situation. The vast majority admitted patients during the pandemic and use PPE. Only almost half plan to be vaccinated.

Protective Factors for Early Childhood Caries in 3-Year-Old Children in Poland.

Background: Early childhood caries (ECC) remains highly prevalent in preschool children worldwide. Dental caries affects every second 3-year-olds in Poland. The aim of the study was to assess protective factors for ECC in 3-year-olds. Methods: A cross-sectional survey was conducted in 2017 among 3-year-olds attending kindergartens in all 16 provinces of Poland. The questionnaire included socioeconomic factors, and oral health behaviors. Decayed, missing due to caries and filled teeth and surfaces were assessed. Caries indices (dmft and dmfs), percentage of caries-free and severe ECC (S-ECC) were calculated. The Student's t-test, Spearman correlation, univariate and multivariate logistic regression (the odds ratios (OR) and adjusted odds ratios (AOR): confounding factors: socioeconomic conditions, oral health behaviors) were performed; p < 0.05. Results: A total of 1,638 children were included. ECC was confirmed in 41.1%; S-ECC in 23.4%. The dmft index was 1.85 ± 3.14, dmfs = 2.99 ± 6.56. Spearman correlation [socioeconomic factors, especially mother's education (r = -0.148, p < 0.001) and family's economic status (r = -0.071, p = 0.004)], despite were statistically significant, indicate very weak relationships with dmft index. After 12th month of life not giving any beverages before bedtime and at night, but water or unsweetened milk only, healthy snacking (sandwiches, fresh fruit), or water on a daily basis decreases the probability of caries development (for S-ECC: OR = 0.37, AOR = 0.47, AOR2 = 0.37; p < 0.01), even if inappropriate dietary behaviors or hygiene practices were simultaneously present. Brushing of a child's teeth twice a day lowered the odds of caries (for S-ECC: OR = 0.78, p = 0.031; AOR = 0.81, p = 0.081; AOR2 = 0.84, p = 0.131), but this effect was less intense when inappropriate dietary behaviors were accounted for. Children of parents with good self-assessment of their teeth were more often caries-free (61.4 vs. 42.9%; p = 0.006) and had lower dmft indices (1.67 vs. 2.93; p = 0.002). Conclusions: Preventing a child after 12th month of life from getting any beverages before bedtime, water or unsweetened milk only, sandwiches and fresh fruit as snacks, or water given to on a daily basis, tooth brushing twice a day decrease the odds of caries in 3-year-olds. Diet appears to have primary significance in the etiology of ECC, since tooth brushing can only partly attenuate the impact of inappropriate dietary behaviors on dental caries. Children are more often caries-free and have lower severity of caries if their parents' dentition is self-assessed as healthy.

Association of parental-reported vitamin D supplementation with dental caries of 3-year-old children in Poland: a cross-sectional study.

OBJECTIVE: The study aimed to assess the association between parental-reported vitamin D supplementation and caries in a national sample of 3-year-olds in Poland. MATERIALS AND METHODS: A total of 1900 children, representing all provinces of Poland, were invited. The questionnaires concerned vitamin D supplementation, socio-demographics, and oral health behaviours. Based on dental examination, caries scores (dmft/dmfs), prevalence of early childhood caries (ECC) and severe ECC (S-ECC) were calculated. The Spearman's correlation, linear regression and logistic regression were used to assess the association between various factors and caries (p < 0.05). RESULTS: A total of 1638 children were tested. Of this number, 99.1% infants were supplemented with vitamin D. Supplementation had been continued seasonally in 55.2% children. ECC/S-ECC prevalence were significantly lower in children receiving vitamin D (ECC 38.3% vs. 44.7%, OR = 0.77; S-ECC 20.5% vs. 27.1%, OR = 0.69; p < 0.05). Mean dmft/dmfs were lower in those with supplementation (1.54 ± 2.72 vs. 2.24 ± 3.55; 2.40 ± 5.56 vs. 3.72 ± 7.56, respectively; p < 0.001). After controlling for confounding factors, supplementation was not significantly associated with caries; only dt/ds were still associated. Maternal education, sweetened beverages before bedtime, bottle use were significantly associated with S-ECC. CONCLUSIONS: Lower caries prevalence was observed in those with vitamin D supplementation. The association between parental-reported vitamin D and ECC/S-ECC was not significant in Polish children. Decayed teeth and supplementation were still associated. Dietary habits can modify the association with caries. CLINICAL RELEVANCE: There may be an association between vitamin D supplementation and lower caries in children. Parents should supplement their children during periods of significant growth and development.

Clinical Effect of Two Fluoride Varnishes in Caries-Active Preschool Children: A Randomized Controlled Trial.

The prevention of dental caries in preschool children is a priority for dental services. The aim of the study was to investigate the caries-preventive effect of 2 fluoride varnishes in caries-active preschool children, and then compare the outcome with a non-varnish control group. After screening, 180 preschool children aged 36-71 months, with at least 1 noncavitated lesion, were enrolled and randomly allocated into 3 parallel groups, namely A: 1.5% ammonium fluoride varnish (Fluor Protector S), B: 5% NaF varnish (Duraphat), and C: professional tooth-cleaning. All children were recalled every third month for intervention and their parents were instructed to have them brush their teeth with a 1,000-ppm fluoride toothpaste twice daily. Caries were recorded at baseline and after 12 months by a calibrated examiner and the incidence was scored on noncavitated (d2) and cavitated (d3) level. We tested differences between the groups with the χ2 and two-sided t tests. One hundred and seventy-two children (95.6%) completed the trial and 56 (32.6%) and 35 (19.2%) developed new d2 and d3 lesions, respectively. Both varnishes reduced the incidence of caries compared with the control group, but there was no significant difference between group A and group B. Compared with group C, the relative risk for developing cavitated lesions was 0.39 (95% CI 0.22-0.62) in group A and 0.26 (95% CI 0.14-0.50) in group B. The total prevented fraction (Δd2d3mft) for group A and group B was 19.9 and 22.5% (p < 0.05), respectively. No adverse effects were observed or reported during the study period. In conclusion, the 2 fluoride varnishes demonstrated an equal capacity to reduce the incidence of caries in caries-active preschool children over a 12-month period in comparison with a control group.

Clinical study on resin composite and glass ionomer materials in II class restorations in permanent teeth.

BACKGROUND: Glass ionomer cements (GIC) used for restoration of missing dental structures have high biocompatibility and remineralization potential. However, low mechanical resistance excludes their use for long-term restorations of extensive lesions, particularly on approximal surfaces in permanent dentition. GIC with increased viscosity have much better physical properties, which involves better bonding and wear resistance, so they can be considered as an alternative to composite resin materials. The aim of this study was to perform a clinical and radiological assessment of restorations in permanent teeth, made with an increased viscosity GIC - Equia Fil (Ivoclar Vivadent) with Equia Coat (Ivoclar Vivadent) and composite material - Tetric EvoCeram (Ivoclar Vivadent) in young patients. MATERIAL AND METHODS: A total of 100 cavities on approximal surfaces were filled with the composite material or GIC in 49 patients aged from 12.08 to 19.58 years. During control examinations, the condition of each restoration was assessed with criteria acc. to Hickel et al. Bitewing radiographs had been taken before fillings were placed and after 12 and 24 months. RESULTS: After two years of observations, two GIC restorations were replaced due to loss of retention and staining. The other 96 restorations were given a satisfactory grade. The clinical efficacy of Equia Fil after 24 months was assessed at 95.83%, the Tetric EvoCeram at 100%. The difference was not statistically significant (P=0.145). When GIC was used, there was a higher risk of marginal adaptation deterioration and the occurrence of staining and erosion. Radiographic efficacy of the Equia Fil material for cavity restoration after 24 months was assessed at 93.75%, for the Tetric EvoCeram material at 100%. Differences were not significant statistically (P=0.073). CONCLUSIONS: Tetric EvoCeram and Equia Fil used for the restoration of approximal lesions in premolars and permanent molars have similar efficacy in a 2-year period of observation. Key words:Dental restoration, permanent, composite resins, glass ionomer cements, clinical study.

Erosive Tooth Wear, Presence of Parafunctional Habits and Tooth Injuries-Occurrence in a Group of Children and Adolescents Exposed to Domestic Violence.

OBJECTIVES: To compare the prevalence of parafunctional habits, erosive tooth wear and occurrence of tooth injuries among children being under the care of Social Welfare Centre and children treated in the Department of Children's Dentistry of the Medical University of Warsaw. STUDY DESIGN: The study contains environmental and medical interviews, record-based analysis and clinical examination. Parafunctional habits were rated on the base of dental interviews and clinical examinations. The occlusal surfaces were evaluated by visual examination using modified tooth wear index (TWI). Tooth injuries were reported from a medical interview labeled using Andreasen classification. The consent of the bioethics committee and guardians of children participated in the study was obtained. RESULTS: The study involved 782 patients, including 404 children from dysfunctional families (average age 11,4 ± 3,7) and 378 from ordinary families-control group (8,53 ± 3,92). In the study group we observed higher prevalence of erosive tooth wear (44,66% vs 18,02% p=0,000), dental trauma (9,4% vs 3,44% p=0,001) and a presence of parafunctional habits (67,8% vs 20,4 % p=0,000). CONCLUSION: The occurrence of parafunctional habits, erosive tooth wear and tooth injuries may be an indicator of domestic violence and a component of maltreated child syndrome.

Comparative optimism about infection and recovery from COVID-19; Implications for adherence with lockdown advice.

BACKGROUND: Comparative optimism, the belief that negative events are more likely to happen to others rather than to oneself, is well established in health risk research. It is unknown, however, whether comparative optimism also permeates people's health expectations and potentially behaviour during the COVID-19 pandemic. OBJECTIVES: Data were collected through an international survey (N = 6485) exploring people's thoughts and psychosocial behaviours relating to COVID-19. This paper reports UK data on comparative optimism. In particular, we examine the belief that negative events surrounding risk and recovery from COVID-19 are perceived as more likely to happen to others rather than to oneself. METHODS: Using online snowball sampling through social media, anonymous UK survey data were collected from N = 645 adults during weeks 5-8 of the UK COVID-19 lockdown. The sample was normally distributed in terms of age and reflected the UK ethnic and disability profile. FINDINGS: Respondents demonstrated comparative optimism where they believed that as compared to others of the same age and gender, they were unlikely to experience a range of controllable (eg accidentally infect/ be infected) and uncontrollable (eg need hospitalization/ intensive care treatment if infected) COVID-19-related risks in the short term (P < .001). They were comparatively pessimistic (ie thinking they were more at risk than others for developing COVID-19-related infection or symptoms) when thinking about the next year. DISCUSSION: This is one of the first ever studies to report compelling comparative biases in UK adults' thinking about COVID-19.

Factors Associated with Early Childhood Caries in Polish Three-Year-Old Children.

PURPOSE: To assess the prevalence and associated factors with early childhood caries (ECC) in a Polish population. MATERIALS AND METHODS: A cross-sectional study was carried out involving 656 three-year-old preschool children of both sexes. Data were collected through oral examination of the children and a questionnaire self-reported by their parents. The questionnaire contained information on sociodemographic aspects, feeding and oral hygiene practices, dental care utilisation and dental health knowledge. Associations between ECC and caries-related factors were analysed with use of bivariate and multivariate logistic regression and Mann-Whitney U test. RESULTS: ECC was diagnosed in 64.0% children from the rural area and 46.6% from the urban one, more often in boys (57.7%) compared to girls (49.5%) and S-ECC in 37.1%, 24.2%, 31.5% and 27.5%, respectively. The associations between caries experience and living in a rural area, male sex, education level and oral health-related knowledge of a parent, tooth brushing frequency, nocturnal bottle-feeding and feeding with sweet beverages at the age over 12 months, consumption of sweetened within the first 2 years of age and drinking of sweet beverages once a week at bivariate level were found. In the final model of the logistic multivariate regression analysis, seven variables were associated with ECC experience. They revealed the probability in decreasing order: living in a rural area (odds ratios (OR) = 1.90); feeding the child during the first 2 years with sweetened food (OR = 1.77); nocturnal drinking of sweet beverages by the >12-month-old child (OR = 1.73); education level of parent (OR = 1.53); gender - male (OR = 1.48); nocturnal bottle-feeding of the over-12-month child (OR = 1.44); and frequency of tooth brushing (OR = 1.41). CONCLUSION: The most prominent risk factors for ECC were living in a rural area, consumption of sweetened foods within the first 2 years of age and nocturnal drinking of sweet beverages by the over 12-month-old child.

Self-Reported Oral Health Knowledge and Practices During Pregnancy and Their Social Determinants in Poland.

PURPOSE: To determine the effects of sociodemographic and pregnancy-related factors on oral health attitudes during pregnancy, as well as the main predictors of proper oral practices. MATERIALS AND METHODS: An electronic survey consisting of 47 (single or multiple-choice) questions was conducted in women up to 3 years after childbirth in 2017. Sociodemographic data, as well as information on the course of pregnancy and delivery, oral knowledge and basic behaviours during pregnancy were collected. The Chi-square test and Spearman's rank correlation coefficient were used for statistical analysis. Odds ratios were determined. A statistical significance level of 0.05 was used. RESULTS: A total of 2480 questionnaires completed by women aged between 13 and 45 years who were up to 3 years after delivery, were analysed. Correct answers to all questions regarding basic oral health and oral practices were obtained by 20.8% and 19.6% of respondents, respectively. Proper health behaviours were more strongly correlated with the level of knowledge (r = 0.155; odds ratio (OR) = 2.44; CI:1.93-3.07; p <0.001) and the use of dental care before pregnancy (r = 0.187; OR = 2.88; CI:2.29-3.63; p <0.001) rather than age (r = 0.144), good or very good financial status (r = 0.110), high level of education (r = 0.081), urban residence (r = 0.058) or occupational activity (r = 0.049). Attending dental visits depended on the conviction about their safety (r = 0.195; OR = 2.47; CI: 2.09-2.93; p <0.001) as well as gynaecologist's referral in the case of general conditions in pregnancy (r = 0.052) and the risk of premature birth (r = 0.053). No effects of other parameters associated with pregnancy or delivery were confirmed. CONCLUSION: Health attitudes during pregnancy are modified by sociodemographic factors. The main predictors of proper health behaviours include high level of knowledge on oral health and the use of dental care before conception. Furthermore, dental attendance among pregnant women depends on the awareness of the safety of dental visits and a gynaecologist referral in case of general condition and risk of premature birth.

Oral Findings in Children, Adolescents and Adults with Tuberous Sclerosis Complex.

Objectives: Tuberous sclerosis complex (TSC) is a multisystem genetic disorder characterized by the development of benign tumors. The aim of the study was to assess the prevalence of oral lesions in patients with TSC and healthy individuals. Study design: The study included 120 patients aged 1.1 to 42.7 years: 60 patients with TSC and 60 controls. Clinical assessment of oral hygiene (Plaque Index-PLI), gingiva (Gingival Index-GI, Gingival Overgrowth Index-GOI), oral mucosa and dentition (caries, tooth wear, enamel defects) was performed. Statistical analysis was performed. Results: 40 patients with TSC received anticonvulsants. Neglected hygiene (PLI: 1.50±0.96 vs 0.92±0.72), gingival hyperplasia (50.0% vs.1.7%), gingivitis (80.7% vs. 53.4%), oral mucosal fibromas (10.0% vs. 0.0%), mucous membrane traumatic lesions (11.7% vs. 1.7%), enamel pits and hypoplasia of incisal borders (41.7% vs. 6.7%), tooth wear (35.0% vs. 11.7%) were more common in patients with TSC compared to controls; increased gingival hyperplasia was correlated with vigabatrin and levetiracetam treatment (r = 0.266 and 0.279, respectively), gingivitis was correlated with PLI (r= 0.635). Conclusions: Although gingival fibromas in TSC are independent of patient's age, young age, anticonvulsant therapy and local factors increase their severity. Enamel defects in TSC include pits, but also enamel loss on the incisal edges and tooth wear.

Polymorphism in the CAVI gene, salivary properties and dental caries.

Objectives: Carbonic anhydrase (CA) VI is supposed to take part in pH or buffering capacity regulation, which can influence the caries risk of an individual. Its expression in the saliva can be modified by single nucleotide polymorphism (SNP). The aim was to investigate SNP in the CA VI gene in relation to active dental caries and physiochemical properties of saliva.Materials and methods: One hundred and thirty participants aged 11-16 years were involved. Clinical examinations were carried out using standardized WHO criteria, DMFT/DMFS and white spot lesions score was evaluated. Saliva samples were examined for salivary properties and CA VI concentration. DNA evaluated in the investigation was extracted from the buccal smear. Three SNP within CAVI gene (rs2274327; rs2274328; rs2274333) were selected and genotyping was performed.Results: In the active caries group, the mean CAVI concentration was significantly lower than in caries free group (p = .014). No association between increased or decreased risk of caries and analysed SNPs was found. There were some significant relations concerning SNPs and salivary buffer capacity and flow rate in rs2274327 and rs2274328.Conclusions: Polymorphism in the CAVI gene can affect salivary properties but there is no direct connection with dental caries.

Excessive computer use as an oral health risk behaviour in 18-year-old youths from Poland: A cross-sectional study.

Background: Many studies have indicated that the excessive use of computers (more than 3 hr/d) might be associated with an unhealthy life-style. Aim: The aim of this study was to evaluate the relationship between excessive computer use with the condition of the teeth and periodontium and the oral health behaviour of 18-year-olds. Design: Cross-sectional studies, using a questionnaire, were carried out on 1,611 18-year-olds from Poland. The questionnaire contained questions about socioeconomic status and information about health-related behaviour. The condition of their teeth and gingivae were clinically assessed. Results: Excessive (>3 h/d) computer use was reported by 492 (31%) of participants, who had an increased frequency of unfilled cavities (1.97 vs. 2.27, p = .047) and a higher risk of oral hygiene neglect (e.g., using dental floss 41% vs. 34%, p = .009). Excessive computer use was also seen to be associated with poor dietary habits. Individuals who declared excessive computer use also had a higher risk of gingival bleeding (35% vs. 29%, p = .009). Conclusion: In the group studied, excessive computer use by adolescents constituted a risk factor for neglect of oral hygiene, poor dietary choices, and failure to benefit from oral health care. Therefore, these aspects should be included in the risk assessment of oral disease and incorporated into educational programs that promote a healthy lifestyle.
