Construct Validity of the Orientation to Life Questionnaire in a General Adult Population in Norway and Its Association with Self-Reported General and Oral Health.

Objective: Individuals' Sense of Coherence (SOC) is measured with the Orientation to Life Questionnaire (OLQ-13). SOC reflects a person's orientation to life and ability to manage stress, which can impact health. The aim of the study was to test the reliability and construct validity of the OLQ-13, with self-reported general and oral health as criterion measures, in a Norwegian general adult population.

Changing from disease-centred to person-centred - Swedish dental hygienists' views on a theory-based behavioural intervention for improved oral hygiene among adolescents.

Objectives: To explore dental hygienists' (DHs') views on (i) a person-centred, theory-based, behavioural intervention for improving oral hygiene among adolescents and (ii) professional and organizational factors to consider in the implementation of such an intervention in daily dental practice.

Methods: Semi-structured interviews were conducted with 13 DHs who had applied the person-centred, theory-based, behavioural intervention directed at adolescents with poor oral hygiene in a field study within the Public Dental Service, Region Västra Götaland, Sweden. The interviews were audio-taped, transcribed verbatim and analysed using qualitative content analysis.

Long-term effects of motivational interviewing vs. traditional counseling on dog owners' adherence to veterinary dental home care: a three-year follow-up study.

Introduction: Periodontal disease is one of the most common health issues in dogs. However, disease is largely preventable by eliminating dental plaque, best achieved by daily tooth brushing. Unfortunately, owner adherence is low to the recommendation of daily tooth brushing in dogs.

The educational gradient in dental caries experience in Northern- Norway: a cross-sectional study from the seventh survey of the Tromsø study.

Background: Although, studies from Norway indicate a reduction in dental caries experience, in Northern-Norway this non-communicable oral condition is still prevalent. There is conflicting evidence of presence of social inequalities in dental caries in an adult population. Therefore, the aim of this study was to assess an association between educational level and dental caries experience in adults in urban Tromsø municipality, Northern-Norway, using The World Health Organization (WHO) Commission on Social Determinants of Health (CSDH) framework of health determinants.

Sense of coherence in a general adult population in Northern Norway and its associations with oral health.

Background: Sense of coherence (SOC) is a global orientation to life that may affect a person's way of acting and living within his or her life context, which can have an impact on general and oral health. The aims of this study were (i) to describe the distribution of SOC in a general adult population; (ii) to explore whether sociodemographic characteristics, oral health-related behaviours, self-reported oral health, and clinical oral status were associated with SOC; and (iii) to explore whether SOC was associated with self-reported oral health, controlling for sociodemographic characteristics, oral health-related behaviours, and oral clinical status.

Methods: This study was based on data from the cross-sectional population-based study Oral Health in Northern Norway (N = 1819 individuals, 923 women, mean age 47.

Oral health-related quality of life in 4-16-year-olds with and without juvenile idiopathic arthritis.

Background: Few studies have investigated oral health-related quality of life (OHRQoL) in young individuals with juvenile idiopathic arthritis (JIA). Aims were to investigate whether OHRQoL differs between children and adolescents with JIA compared to controls without JIA, while adjusting for socio-demographic-, behavioral- and oral health-related covariates. Furthermore, to explore whether socio-behavioral and oral health-related covariates of OHRQoL vary according to group affiliation and finally, specifically for individuals with JIA, to investigate whether disease-specific features associate with OHRQoL.

Relationship between periodontitis and risk of cardiovascular disease: Insights from the Tromsø Study.

Background: Few large-scale studies have investigated the association between periodontitis and cardiovascular risk estimated by risk assessment models; moreover, this association remains unexplored in never-smokers. We aimed to examine the relationship between periodontitis and cardiovascular risk in a Norwegian general population, with a focus on never-smokers and the impact of sex and age.

Methods: The present study included 2623 participants from the seventh survey of the Tromsø Study (Tromsø7, 2015-2016), aged 45-74 years, and without previous myocardial infarction or stroke.

Oral health related quality of life in long-term survivors of head and neck cancer compared to a general population from the seventh Tromsø study.

Background: Both the incidence and survival rate of head and neck cancer (HNC) is increasing, making quality of life of HNC survivors an important issue.

Methods: In this cross-sectional study we compared the oral health related quality of life (OHRQoL) of long-term HNC survivors to that of a general population cohort from the seventh survey of the Tromsø study with the Oral Impact on Daily Performances questionnaire. Comparisons were done with frequency analyses and cross tabulation.

A person-centred, theory-based, behavioural intervention programme for improved oral hygiene in adolescents: A randomized clinical field study.

Aim: To test the effectiveness of a person-centred and theory-based educational intervention to increase adolescents' adherence to adequate oral hygiene behaviour, that is, self-performed periodontal infection control.

Materials And Methods: Data were derived from a prospective, multi-centred, two-arm, quasi-randomized field study in which treatment was performed by dental hygienists (DHs) within the Public Dental Service, Västra Götaland, Sweden.

Results: Women had a higher prevalence of all self-reported and clinical signs of pain and dysfunction in the temporomandibular complex compared to men.

Oral health and use of dental services in different stages of adulthood in Norway: a cross sectional study.

Background: Socioeconomic status and oral health care habits may change throughout adult life. This calls for age-stratified analyses of oral health in the adult population to uncover differences that could be of importance for organizing adequate oral health care services. The aim of the present study was to describe self-reported oral health in different age groups in a general adult population in Norway, and to explore associations between self-reported oral health and age groups, sociodemographic factors, use of dental services, number of teeth and dental caries.

Caries experience among adults in core Sámi areas of Northern Norway.

Objectives: Dental caries is a major oral health problem among indigenous people worldwide, but knowledge on this issue among the indigenous Sámi people in Norway is scarce. The aim of the study was to describe dental caries experience in an adult population in core Sámi areas of Northern Norway and to assess the corresponding associations with socio-demographic, socioeconomic and oral health-related behavioural factors.

Methods: This cross-sectional study is based on data from the Dental Health in the North study (2033 participants aged 18-75 years).

Overcoming behavioral obstacles to prevent periodontal disease: Behavioral change techniques and self-performed periodontal infection control.

It is well established that periodontal infection control, by means of adequate oral hygiene such as daily toothbrushing and interdental cleaning, is essential for prevention of periodontal disease. Evidence suggests that oral health behavioral intervention is more effective if based on a theoretic framework that includes behavioral change techniques based on goals and planning and on feedback and monitoring. This review focuses on factors that influence behavioral changes in oral hygiene measures (both obstacles and facilitators) and a person-centered approach to treatment planning and communication with patients.
