Objective: The aim of the study was to evaluate patterns of caries experience in a representative sample of Lithuanians, aged 65-74.

Methods: This cross-sectional study included 301 participants (response rate 54%). Information was obtained from a clinical examination (caries experience, stimulated salivary flow rates and oral hygiene levels) and a questionnaire.

Clinical performance of 3 endodontic sealers.

Objective: Calcium hydroxide is used in endodontics as an interappointment dressing. Its inclusion in salicylate resin or zinc oxide-eugenol-based sealers for filling root canals also may lead to a better treatment outcome. The purpose of the present study was to compare the clinical/radiographic treatment outcome of 3 sealers, 2 of which contain calcium hydroxide.

Caries in populations--a theoretical, causal approach.

The focus of this paper is caries in populations. Caries is assessed as a phenomenon and as it occurs in populations. It is observed that in recent literature the notion of causation of caries is restricted to the biological process on the tooth surface.

Thoroughly modern worries: the relationship of worries about modernity to reported symptoms, health and medical care utilization.

Objective: There is now greater public concern about how features of modern life pose threats to personal health. In two studies, we investigated the relationship between individuals' worries about modernity affecting health to symptom reports, perceptions of health and health care utilization.

Methods: In the first study, 526 University students completed a questionnaire measuring modern health worries (MHW), symptom reports and health perceptions.

Is the observed association between periodontitis and atherosclerosis causal?

Most of the documentation of possible causal links between periodontitis and atherosclerosis-related diseases appears indirect or circumstantial. There is, however, an increasing number of both experimental and longitudinal epidemiological studies which seem to support a causal relationship. A critical evaluation of the epidemiological data available might therefore be appropriate.

Influence of coronal restorations on the periapical health of endodontically treated teeth.

The purpose of the study was to evaluate a possible relationship between the quality of the coronal restoration, the root canal obturation and the periapical status of endodontically treated teeth. Full mouth series of radiographs from randomly selected patient charts at the Dental Faculty, University of Oslo were examined. A total of 1001 endodontically treated teeth restored with a permanent restoration were evaluated independently by two examiners.

Isolation of Enterococcus faecalis in previously root-filled canals in a Lithuanian population.

The occurrence of Enterococcus faecalis in root canals of previously root filled teeth with apical periodontitis requiring retreatment was studied in Lithuanian patients. Twenty-five asymptomatic teeth were included in the study. Avoiding contamination microbiological samples were taken from the canals before and after preparation and irrigation with sodium hypochlorite and EDTA.

Oral health behavior and attitudes of adults in Lithuania.

In Lithuania, the oral health system is currently in transition and systematic data are needed for public oral health care planning. The objectives of this study were (i) to describe the self-assessment of oral health status in Lithuanian adults, the oral hygiene practices, and dental visiting habits; (ii) to assess the attitudes towards teeth and oral health, dental care and oral health services; (iii) to determine whether oral health attitudes and behavior are affected by socio-economic factors; and (iv) to analyse the association between self-care practices and use of oral health services. The study comprised random samples of 35-44-year-olds (n = 381) and 65-74-year-olds (n = 302).

The concept of disease: ethical challenges and relevance to dentistry and dental education.

Modern medicine and dentistry face fundamental ethical challenges. To treat or not to treat, that is the question! Can these challenges be met with a rigorous and consistent concept of disease? This is the key question of this article and the ensuing debate is of fundamental importance in the teaching of ethics to medical and dental students. The investigation of traditional concepts of disease reveals that they are flawed and do not withstand ethical challenges.

Prevalence and determinants of periodontal disease in Portuguese adults: results from a multifactorial approach.

The purpose of the present investigation was to study prevalence of periodontal disease among 30 to 39-years-old from Oporto in the north of Portugal. In addition, an attempt was made to elucidate possible periodontal disease determinants in this population. A random sample consisting of a total of 322 individuals was drawn based on electoral lists.

Autosomal dominant cone-rod dystrophy due to a missense mutation (R838C) in the guanylate cyclase 2D gene (GUCY2D) with preserved rod function in one branch of the family.

We present the clinical and molecular genetic features of a large multi-generation Norwegian family with dominant cone-rod dystrophy. Ophthalmological evaluation including electroretinography showed cone dysfunction in younger patients, with rod dysfunction becoming apparent at more advanced stages of the disease. In one branch of the family, cone degeneration remained the only manifestation despite advancing age.

Effects of psychological defense on processing of neutral stimuli indicated by event-related potentials (ERPs).

The Defense Mechanism Test (DMT) is claimed to identify personnel with a high risk for accidents. A new explanation for why the DMT seems to predict performance when survival depends on split second decisions is proposed. Sixteen right-handed, adult male students were tested with the DMT and with an ERP paradigm (two sine wave tones, presented binaurally).

Dental caries in adult Lithuanians.

There are few data on the incidence of dental caries in Lithuanian adults. The aim of the present study was to describe caries and treatment experience among 35-44 and 65-74-year-olds, and to relate this to certain selected independent variables (gender, urban/rural residence, drinking water fluoride levels, and years of education). A total of 680 subjects selected based on a stratified random sampling procedure (response rate 52%) were examined by one examiner.

Variation in caries and treatment experience in 35-44-year-old Lithuanians.

Data summarising caries levels differ between countries and often conceal large variations. These differences may reflect variations at individual, group, social and other levels. Caries and treatment experience differences are found to be significantly related to a variety of clinical and non-clinical factors.

Does early intervention with a light mobilization program reduce long-term sick leave for low back pain?

Study Design: A controlled randomized clinical trial was performed.

Objective: To investigate the effect of a light mobilization program on the duration of sick leave for patients with subacute low back pain.

Summary Of Background Data: Early intervention with information, diagnostics, and light mobilization may be a cost-effective method for returning patients quickly to normal activity.

Apical periodontitis and related factors in an adult Lithuanian population.

Objectives: The objectives of this investigation were to study determinants of apical periodontitis among Lithuanians who were 35 to 44 years old and to study possible associations between apical periodontitis, relevant general diseases, and perceived general health.

Study Design: Information was collected from a randomly selected sample, consisting of 147 individuals from Vilnius, Lithuania. Aspects of oral and general health, health-related habits and attitudes, and social parameters were used as independent variables, with various aspects of apical periodontitis as the dependent variable.

A scoring system for subjective health complaints (SHC).

The aim of this study is to present a complete scoring system for subjective health complaints (SHC) as they are experienced by the lay population. The scoring system records the complaints, and does not map attributions or medical diagnoses. In all, 1,219 subjects (323 men, 896 women) from various occupations were tested with a scoring system, the SHC inventory, previously referred to as the Ursin Health Inventory (UHI).

Endodontic treatment and prevalence of apical periodontitis in an adult population of Vilnius, Lithuania.

Apical periodontitis is prevalent in many Western populations and is frequently detected in connection with inferior quality of endodontic treatment. However, information about endodontic conditions from eastern European countries is limited. The aim of the present investigation was to study the prevalence of apical periodontitis and the quality of endodontic treatment in 35-44-year-old Lithuanians.

Immunochemical characterization of assay for carboxyterminal telopeptide of human type I collagen: loss of antigenicity by treatment with cathepsin K.

The assay for the cross-linked carboxyterminal telopeptide of type I collagen (ICTP) has been shown to reflect increased type I collagen degradation in such pathological conditions as bone metastases and rheumatoid arthritis, but to be rather insensitive to the changes in physiological bone collagen turnover (e.g., induced by estrogen or bisphosphonate treatment).

Prevalence of apical periodontitis and results of endodontic treatment in an adult, Portuguese population.

The present epidemiological study is derived from a random sample of 322 residents of the Porto area, aged 30-39 years. Prevalence of apical periodontitis and results of endodontic treatment were evaluated from orthopantomograms, available from 179 of a total of 197 individuals attending for examination. The results indicated a prevalence of apical periodontitis in 27% of this population.

The time dimension in stress responses: relevance for survival and health.

Within the Cognitive Activation Theory of Stress (CATS), the stress response occurs whenever there is a discrepancy between what the organism is expecting, and what really exists. It affects the biochemistry of the brain, mobilizes resources, affects performance, and endocrine, vegetative, and immune systems. Initial positive feedback and feed-forward mechanisms are gradually changed by homeostatic mechanisms.

Has caries merely been postponed?

During the last 25 years there has been a substantial caries decline among children and adolescents in many Western societies. Recent epidemiologic data show a reduced caries prevalence also in young adult cohorts, indicating that the caries reduction is maintained into adulthood.

The CODE: a revised battery for coping and defense and its relations to subjective health.

A condensed test battery (the CODE) based on the Utrecht Coping List (UCL) and part of the Defense Mechanisms Inventory (DMI) has been developed to assess coping and defense in large population studies. It was tested for reliability and validity in students and back pain patients. Principal components factor analysis of the subscales of the UCL and DMI in the student sample revealed two coping clusters: "Instrumental mastery-oriented coping" and "Emotion-focused coping" and two defensive clusters: "Cognitive defense" and "Defensive hostility".
