Objectives To assess the prevalence and determinants of xerostomia among adults and identify how many of the ones experiencing xerostomia have Sicca and Sjogren's syndromes. Materials and methods This cross-sectional study included 1405 35–74-year-old Lithuanians (51.7% response rate) from the five largest Lithuanian cities and 10 peri-urban and rural areas that were randomly selected from each of the 10 Lithuanian counties. Xerostomia was determined by the self-reported experience of dry mouth as "often" or "always". A dentist diagnosed Sicca syndrome by unstimulated whole sialometry and the Schirmer's test, and all cases were referred to a rheumatologist to confirm Sjogren's syndrome. Self-reported questionnaires collected data about the determinants. Results The prevalence of xerostomia was 8.0% (n = 112), Sicca syndrome was diagnosed for 8 participants (0.60%), and Sjogren's syndrome for 2 participants (0.14%), with this being the first time it was diagnosed. Experiencing xerostomia was associated with older age (OR 1.7, 95% CI 1.1–2.6), urban residence (OR 3.3, 95% CI 1.6–5.0), presence of systemic diseases (OR 2.5, 95% CI 1.4–3.3), and the use of alcohol (OR 0.6, 95% CI 0.4–0.9). The higher proportion of participants with Sicca syndrome involved females, of older age, having systemic diseases, and using medications. Conclusions The prevalence of xerostomia was 8.0% and the determinants of xerostomia were older age, urban residence, systemic diseases, and absence of using alcohol. In total, 0.6% of participants had Sicca syndrome, which was more prevalent among females, older subjects, those with systematic diseases, and those using medications. Sjogren's syndrome was diagnosed in 0.14% of participants. Clinical relevance Dental clinicians need to be trained to identify potential Sjogren's syndrome cases.
<b><i>Introduction:</i></b> Erosive tooth wear has a multifactorial origin, where multiple risks contribute to its initiation and subsequent progression. The prevalence of tooth wear varies among countries; therefore, national studies are needed to examine the prevalence of this condition and its associated determinants. <b><i>Materials and Methods:</i></b> A sample of this national study included a total of 1,397 adults (response rate of 52%). Severity and number of teeth with erosive tooth wear, caries experience (D<sub>3</sub>MFS), and fluorosis were assessed clinically. A self-reported questionnaire inquired about sociodemographics, oral health behavior, diet, and general health. Fluoride levels in drinking water at the recruitment areas were also recorded. Data were analyzed by bivariate and multivariate methods. <b><i>Results:</i></b> The prevalence of erosive tooth wear in enamel and dentin combined was 59% among 35- to 44-year-old, 75% among 45- to 54-year-old, 70% among 55- to 64-year-old, and 66% among 65- to 74-year-old males. The prevalence among females in the respective age groups was 44, 60, 63, and 59%. Erosive tooth wear in enamel was associated with a lower fluoride level (≤1 ppm) in the drinking water (OR 2.1, 95% CI 1.1–4.2). Erosive tooth wear in dentin was positively associated with male gender (OR 1.7, 95% CI 1.1–2.5), periurban/rural residency (OR 1.6, 95% CI 1.1–2.4), older age (OR 1.6, 95% CI 1.3–1.9), presence of reflux (OR 3.3, 95% CI 1.0–10.9), and negatively with higher D<sub>3</sub>MFS scores (OR 0.7, 95% CI 0.5–0.9). <b><i>Conclusions:</i></b> The prevalence of erosive tooth wear in enamel and dentin was relatively high in Lithuania; the erosive tooth wear in enamel and dentin combined was 52% among 35- to 44-year-olds, 68% among 45- to 54-year-olds, 67% among 55- to 64-year-olds, and 63% among 65- to 74-year-olds. Lower fluoride level in drinking water was associated with erosive tooth wear in enamel. Male gender, residency in periurban/rural areas, older age, and presence of acid reflux were associated with higher odds, while higher D<sub>3</sub>MFS scores were associated with lower odds for erosive tooth wear in dentin. These results can be used to plan dental public health prevention.
Background There is no recent information about dental service utilization (DSU) among elderly in Lithuania. We examined DSU and its associated factors in Lithuanian early elderly based on the Andersen’s behavioural model. Methods The cross-sectional study conducted in 2017–2019 included a nationally representative stratified sample of 370 Lithuanian early elderly aged 65–74 years (response rate of 54.5%). Information on predisposing factors (age, sex, nationality and education), enabling factor (residence), need-based factors (status of teeth, oral pain or discomfort, and dry mouth), general health, personal health practices and perceived stress was obtained from a structured, self-administered questionnaire. Clinically-assessed need-based factors included number of missing teeth and dental treatment need. Multivariable Poisson regression with robust variance estimates was used. Results A total of 239 study participants (64.6%) reported a dental visit during the last year and 338 (91.4%) needed dental treatments. A higher level of education (adjusted prevalence ratio [aPR] = 1.21, 95% confidence interval [CI]:1.04–1.40), pain or discomfort in teeth/mouth (aPR = 1.35, 95%CI: 1.13–1.62) and lower number of missing teeth (aPR = 0.99, 95%CI: 0.98–1.00) were associated with DSU. Conclusions Even though majority of early elderly needed dental treatments, only two-thirds visited a dentist during the last year. Predisposing and need-based factors were significant predictors of having a dental visit in the last year. A national oral health program for Lithuanian elderly with the focus on regular preventive dental check-ups is needed. More studies, both quantitative and qualitative, are warranted to investigate in depth the barriers for DSU among elderly in Lithuania.
According to the World Health Organization (WHO) oral conditions may be determined by social, biological, behavioral, and psychosocial factors. The study assessed oral health status and its determinants associated with oral health conditions among adult residents in Vilnius, Lithuania. A total of 453 of 35–74-year-olds participated (response rate 63%). A self-reported questionnaire was administered. Dental caries experience (D3MFS score), periodontal probing depth (PPD), andnumber of missing teeth were assessed clinically. Data were analyzed using χ2 test, independent samples t-test, and multivariable linear regression. The mean (sd) of D3MFS scores was 67.3 (33.5), the mean (sd) number of teeth with PPD 4+ mm was 5.9 (5.3), prevalence of periodontitis was 33%, the mean (sd) number of missing teeth was 6.9 (6.8), and prevalence of total edentulism was 3.8%. Medication use was associated with all oral health conditions, while age was associated with caries experience, and missing teeth. Sugar-containing diet was associated with caries experience, and missing teeth, and smoking with caries experience and periodontal status. Systemic diseases were associated with periodontal status, while behavioral determinants, last dental visit, and use of fluoridated toothpaste were associated with missing teeth. Oral health status among adult Vilnius residents was poor. Oral conditions were associated with both biological and behavioral determinants. Oral health promotion should focus on modifying behavioral determinants.
Introduction: Genetic biomarkers have the potential to be used in personalised dentistry for improved prevention and decision-making in caries management. The amylase alpha 1 gene (AMY1) encodes salivary α-amylase and may be one such biomarker. We examined the association between AMY1 copy number variation (CNV) and dental caries experience in adults. Materials and Methods: A stratified random sample of 193 participants from the Lithuanian National Oral Health Survey (LNOHS) agreed to provide saliva samples and were included in this analysis (age 35–44 years; participation rate 43%). Information on socio-demographic and behavioural characteristics was taken from the LNHOS, which used the self-administered World Health Organisation (WHO) questionnaire. Data on fluoride levels in drinking water at the recruitment areas was recorded based on information provided by water suppliers. Dental caries experience was recorded at a surface level (smooth-surface and occlusal-surface decayed, missing, filled surfaces [D3MFS] score) by one trained and calibrated examiner using WHO criteria, and subsequently dichotomised for the statistical analyses. DNA extracted from saliva samples was used to investigate AMY1 CNV using the QX200 droplet digital PCR system. Bivariate and multivariable statistical analyses were employed. Results: When compared to participants with an AMY1 copy number (CN) of 2–3, higher odds of smooth-surface D3MFS >14 was observed for participants with a CN of 4–5 (OR 13.3, 95% CI 2.1–86.3), 6–9 (OR 7.0, 95% CI 1.4–34.1), and 10–16 (OR 5.8, 95% CI 1.2–32.2). Female sex was independently associated with a smooth-surface D3MFS >14 (OR 5.7, 95% CI 1.9–17.2). Conclusions: Our study demonstrated an association between AMY1 CNV and high smooth-surface caries experience. Studies with larger sample sizes are needed to validate this association.
