Validation of the French version of COHIP-SF-19 among 12-years children in New Caledonia.

BACKGROUND: Assessment of oral health-related quality of life is now associated to clinical indicators in epidemiological studies. This study aimed at validating the French Short Form of the Child Oral Health Impact Profile (COHIP-SF-19) and assessing the impacts of oral diseases among schoolchildren in New Caledonia (NC). METHODS: A sample of 12-years-old children (n = 971) was selected in 2019 in NC using a random, stratified, and clustered sampling technique. Children filled the French COHIP-SF-19 questionnaire. Information on sociodemographic characteristics, oral hygiene habits, perception of oral health problems were also collected through self-administered questionnaires or from the schools' database. Dental status (dental caries, gingival status, and dental functional units) was clinically recorded at school by four calibrated examiners. Cronbach's alpha and intraclass correlation coefficients (ICC) were calculated. Kruskal-Wallis tests and spearman correlations were used along with multilevel mixed models taking into account the cluster and examiner effects. A confirmatory factor analysis was conducted and sensitivity analyses were performed. RESULTS: Among the 693 children examined, 557 children were included. Oral diseases were frequent in the study population 40% had dental caries and 55% presented gingivitis. The COHIP scores ranged from 7 to 76 (57.9 ± 9.96) with 96.4% of the children having experienced oral health problems, 81.7% reporting functional impacts and 90.5% socio-emotional impacts. Overall, the French COHIP-SF-19 showed satisfactory psychometric characteristics. Internal consistency was high (Cronbach's alpha = 0.80) and reproducibility excellent (ICC = 0.9). Discriminant and concurrent validity were adequate. Indeed, children with less optimal social situation, impaired dental status, declaring severe dental problems or difficulties in accessing oral health care showed lower COHIP-SF-19 scores. Factor analyses suggested a four-component structure with identification of a new domain (self -image) and changes in the repartition of the items within the original domains. Sensitivity analyses showed similar results for children with partial or complete answers in the COHIP questionnaire. CONCLUSIONS: The French COHIP-SF-19 showed satisfactory psychometric characteristics and allowed to identify the high impacts of oral diseases in New Caledonian children, namely for socially deprived children.

Identifying people requiring special care dentistry: A scoping review.

AIMS: This scoping review aimed to document tools designed to identify persons requiring special care dentistry (SCD) and to provide a better understanding of the factors that justify adaptation in the provision of care. METHODS: A scoping review methodology was applied. An electronic search was performed in April 2021 using Pubmed and Embase. Additional tools were sought using hand searches and informal professional networking. RESULTS: Ten tools were identified that either predict the complexity of dental management or that retrospectively judge the complexity of care, of which two are as yet unpublished. Some had been developed for a specific population (e.g., patients with Alzheimer's disease, with learning disability, elderly persons) whilst others were applicable for any population (case mix tools). Factors considered included the patient's medical history, ability to cooperate, physical and cognitive autonomy, communication skills, anxiety, need for sedation, oral risk factors, ability to consent and the administrative burden for the dentist. CONCLUSION: Identifying persons requiring SCD is possible by looking at various factors that influence the provision of dental care. There may be need for adaptation of tools to local circumstances and to the intended usage of the tool at a health services, systems or policy level.

How Do Persons With Disabilities and/or Complex Health Conditions Perceive Oral Health? A Qualitative Study.

OBJECTIVES: This qualitative study aimed to explore the experience and perception of the mouth, oral health, functioning and the social environment amongst adults with disabilities and complex health conditions. METHODS: Purposive sampling using the maximum variation strategy was performed to select participants with a wide range of experiences in terms of demographics, disability and health conditions. Consent was sought, and semi-structured interviews were conducted, recorded and transcribed verbatim. Within the interpretivist tradition, a phenomenological approach was used to describe the lived, contextualised experience of people in relation to their mouths, as described by participants. Thematic analysis was undertaken. RESULTS: Eighteen participants with disabilities and complex health conditions were interviewed. Twelve individuals had an intellectual disability. Three main themes were identified: perception of the mouth and oral health; symptomatic perceptions and responses to oral health problems; and inter-relationships between the mouth, oral health and the socio-medical environment. The mouth had a central place in the lives of the participants, but its importance was only recognised when oral health problems interfered with daily life, function, social relationships, family life or autonomy. Certain social determinants of health were identified: social exclusion, financial insecurity, lack of autonomy, nutrition and negotiation of services. Oral problems were perceived as an additional burden to those with disabilities or complex health conditions. CONCLUSION: This study provided insight into the daily lives of adults with disabilities and complex health conditions. It helps to fill the gaps in the existing literature regarding the perceptions of the mouth and oral health, connecting oral function, general health and social environment for this population. TRIAL REGISTRATION: This study was registered into ClinicalTrials.gov (NCT04815434).

Identifying Persons with Special Healthcare Needs in Dentistry-Development and Validation of the French Case Mix Tool.

Providing dental care for certain patient groups is complicated due to difficulties with cooperation, communication, health conditions, and social context, amongst others. The majority of dentists in France work within a public fee-per-item system. A new measure has been introduced providing a financial supplement to dentists for each episode of care for a patient with a severe disability. This supplement is justified by completion of the French Case Mix tool (FCM), a new measure designed to retrospectively identify episodes of dental care that have required adaptation and additional time or expertise. The aim of this study was to investigate the validity and psychometric properties of the FCM. The content validity of the tool was improved at each round of pilot development, involving 392 patient encounters. Test-retest data at 2 weeks for 12 fictional patient treatment episodes were collected from 51 dentists. This phase confirmed inter- and intra-dentist reproducibility, criterion validity, and interpretability. Retrospective analysis of 4814 treatment episodes nationally demonstrated high reliability, internal consistency, and construct validity. Overall, the FCM showed high validity and good psychometric properties. However, the impact of providing a financial supplement on improving access to care for persons with special needs has yet to be evaluated.

Comprehensive Dental Treatment under General Anesthesia Improves Mastication Capability in Children with Early Childhood Caries-A One-Year Follow-Up Study.

BACKGROUND: Using the granulometry of ready-to-swallow food boluses, this study investigated the evolution of masticatory capability of children with Early Childhood Caries (ECC) after comprehensive dental treatment under general anesthesia (GA). METHODS: Sixteen children with ECC were assessed before and over one year after dental treatment under GA, in comparison with 12 children with a Healthy Oral State (HOS). Oral health criteria, quality of life, body mass index, and frequency of orofacial dysfunctions were recorded. Masticatory kinematic parameters and median food bolus particle size (D50) at swallowing were assessed while masticating raw carrot (CAR), cheese (CHS), and breakfast cereals (CER). The impact of posterior teeth extractions was analyzed. RESULTS: Quality of life and orofacial functions improved after dental treatment. Chewing frequency for all three foods increased without reaching the values of children with HOS, while D50 values for CAR and CHS decreased. After one year, children with posterior teeth extractions exhibited higher D50 values for CAR and CHS than children with only conservative treatment. One third of children with ECC were overweight or obese. CONCLUSIONS: Comprehensive dental treatment improved children's mastication, and their BMI subsequently increased. Links between mastication and nutrition should be investigated further in children.

Natural food mastication capability in preschool children according to their oral condition: A preliminary study.

This study investigated, for the first time, the masticatory capability of preschool children using natural foods, and the impact of an early oral health alteration (early childhood caries: ECC) on the granulometry of ready-to-swallow food boluses. Thirteen children with ECC were compared to 13 preschool children with a healthy oral condition. Oral health criteria and NOT-S scores (Nordic Orofacial dysfunction Test-Screening) were recorded. For each child, number of masticatory cycles (Nc), chewing time (Ti), and frequency (Fq = Nc/Ti) were recorded during mastication of raw carrot (CAR), cheese (CHS) and breakfast cereals (CER) samples. Food boluses were collected by stopping children at their food-dependent individual swallowing threshold (Nc), and the median food bolus particle size value (D50) was calculated. Correlations were sought between oral health and masticatory criteria. In the ECC group, mean Fq values were significantly decreased for all three foods (p ≤ .001) and mean D50 values were significantly increased (p ≤ .001) compared to the control group (i.e., D50 CAR = 4,384 µm ± 929 vs. 2,960 µm ± 627). These alterations were related to the extent of ECC. The NOT-S mean global score was significantly increased in children with ECC (2.62 ± 1.37 vs. 1 ± 0.91 in the control group, p ≤ .01), due to "Mastication and swallowing" domain impairment. This study gives granulometric normative values for three foods in preschool children and shows the impact of ECC on D50 values. The progression of children's masticatory capability after dental treatment, and the impact of such modifications of sensory input on future eating habits should be explored.

Identifying common factors of functioning, participation and environment amongst adults requiring specialist oral health care using the International Classification of Functioning, disability and health.

INTRODUCTION: Persons unable to access oral health care in the conventional primary health care setting suffer from inequalities in oral health, particularly in terms of unmet dental need. The International Classification of Functioning, disability and health (ICF) is designed to look beyond medical diagnosis and to describe individuals or populations in terms of their ability to function and participate in a social environment. The objective of the study was to describe an adult population requiring specialist oral health care using the ICF and to identify common factors of functioning, participation and environmental context. METHOD: The ICF Checklist for Oral Health was completed for 246 participants from five specialist dental services in five countries (mean age 36 ±16.44 years; 16-92). 'Developmental disability' and 'Medically compromised' groups were identified (72% and 28%). RESULTS: Participants presented with oral disease (92%) and dysfunction (66% impaired chewing). 33 ICF items were affected in over 50% of participants in both groups. Impaired body functions included 'ingestion functions', 'energy and drive functions' and 'emotional functions'. Participation was restricted for "Acquiring, keeping and terminating a job", "Intimate relationships", "Handling stress and psychological demands", "Economic self-sufficiency", "Carrying out a daily routine", "Recreation and leisure", "Community life" and "Looking after one's health". In the environment domain, "Support and relationships" and "Attitudes" were rated as facilitators. Environmental barriers reported for over 25% of the whole group were related to "Services, systems and policies" including, health, social security, general support, transportation, and labour and employment. DISCUSSION AND PERSPECTIVES: Common aspects of functioning, participation and environment were found amongst a heterogeneous population of adults attending specialist dental services, alongside poor oral health and function. The ICF may be used to describe populations that suffer inequality in oral health in order to develop services that effectively target those in need of additional means.

Using the International Classification of Functioning, Disability and Health (ICF) to describe children referred to special care or paediatric dental services.

Children in dentistry are traditionally described in terms of medical diagnosis and prevalence of oral disease. This approach gives little information regarding a child's capacity to maintain oral health or regarding the social determinants of oral health. The biopsychosocial approach, embodied in the International Classification of Functioning, Disability and Health - Child and Youth version (ICF-CY) (WHO), provides a wider picture of a child's real-life experience, but practical tools for the application of this model are lacking. This article describes the preliminary empirical study necessary for development of such a tool - an ICF-CY Core Set for Oral Health. An ICF-CY questionnaire was used to identify the medical, functional, social and environmental context of 218 children and adolescents referred to special care or paediatric dental services in France, Sweden, Argentina and Ireland (mean age 8 years ± 3.6 yrs). International Classification of Disease (ICD-10) diagnoses included disorders of the nervous system (26.1%), Down syndrome (22.0%), mental retardation (17.0%), autistic disorders (16.1%), and dental anxiety alone (11.0%). The most frequently impaired items in the ICF Body functions domain were 'Intellectual functions', 'High-level cognitive functions', and 'Attention functions'. In the Activities and Participation domain, participation restriction was frequently reported for 25 items including 'Handling stress', 'Caring for body parts', 'Looking after one's health' and 'Speaking'. In the Environment domain, facilitating items included 'Support of friends', 'Attitude of friends' and 'Support of immediate family'. One item was reported as an environmental barrier - 'Societal attitudes'. The ICF-CY can be used to highlight common profiles of functioning, activities, participation and environment shared by children in relation to oral health, despite widely differing medical, social and geographical contexts. The results of this empirical study might be used to develop an ICF-CY Core Set for Oral Health - a holistic but practical tool for clinical and epidemiological use.
