About the statistics
The statistics show the scope of patient treatment in the public dental health service, dental health information on children and adolescents, and public dental health care expenses. In addition, the statistics show the number of FTEs in public and private dental health care.
The public dental health care
The counties are responsible for the public dental health care and for providing dental services for the inhabitants in the county, either by employees in the county or by dentists in private practice who have an agreement with the county.
Prioritised persons belong to one of the groups that have rights pursuant to the law on dental health. Group A consists of children aged 1-18 years and group B consists of mentally disabled persons above 18 years who do not live in an institution or receive home nursing. Group C1 consists of elderly, long-term ill and disabled persons living in institutions, and mentally disabled persons living in institutions. Elderly, long-term ill or disabled people must have lived in the institution for at least three months. Group C2 consists of elderly, long-term ill and disabled persons receiving home nursing. Included here are also mentally disabled people receiving home nursing. Group D consists of youth aged 19-20, with the exception of mentally disabled persons. Other groups that the county chooses to prioritise are referred to as group E . Examples of such patients are prison inmates and persons who receive treatment for substance abuse. Finally, group F consists of the rest of the adult population (not belonging to group A-E).
Under supervision by the public dental health care
The concept "under supervision by the public dental health care" is used about patients who belong to a prioritised group and who undergo a dental health care examination by a dentist or a dental nurse, receive dental treatment or training in preventive dental care, or are offered further examination or treatment. It follows that not all patients are treated/examined during one year.
DMFT (Decayed, Missing, Filled Teeth) expresses the number of teeth that have or have had the need for treatment, and has been lost due to illness.
D signifies the number of teeth with caries, the number of teeth that needs to be repaired at the time of examination as a consequence of caries. M signifies the number of lost teeth as a consequence of disease. F signifies the number of teeth that have been treated as a consequence of caries, often called "teeth with caries experience".
DMFT (with capital letters) signifies permanent teeth, while dmft (with small letters) signifies milk teeth.
Employed persons are persons between 15-74 years of age who performed work for pay or profit for at least one hour in the reference week, or who were temporarily absent from work because of illness, holidays etc. Conscripts are classified as employed persons. Persons engaged by government measures to promote employment are also included if they receive wages. This follows recommendations from the International Labour Organization, ILO.
The age is given in complete years at the end of the year.
If employed persons have more than one employment in the reference week, one is determined as the most important. Information on individuals’ work- and business related variables comes from the main employment.
Characteristics of individuals
Age is defined as years of age at year-end.
Characteristics related to employment
From 2015 onwards: Working hours are calculated using the number of hours per week that constitute a full-time position, the percentage of the position and the number of paid hours.
In a-ordningen occupational code is also delivered for employees in the central government. Previously, the position percentage for this group had to be calculated using statistical methods based on other sources of data.
From 2000-2014: Working hours is the scheduled working hours per week divided into three intervals: 1-19 hours per week, 20-29 hours, and 30 hours per week and above. For 90 per cent of the employed persons, information is obtained from the Ee-register. For those classified as employed persons on the basis of information from The Register of End of the Year Certificates (as one of the sources), the size of the annual income is used to calculate weekly hours of work. The working hours for self-employed persons are the average working hours per week, calculated on the basis of entrepreneurial income and information from the Labour Force Survey, LFS.
For employed persons in the Ee-register, the occupational code is supplied by the employer, or encoded from the occupational title. For other employed persons, the occupational distribution is estimated using statistical methods and other sources of data.
The information about the municipality of work and industry is obtained from the Central Register of Business Establishments and Enterprises (CRE) and uses information on the enterprise where people work. For self-employed who are not related to either an enterprise or an establishment, information on residency, education and the independent enterprise of family members are used to decide the necessary variables. The work place for seafarers and employees in the National defence is set equal to the municipality of residence.
Information about the sector is based on the institutional sector classification and is retrieved from the CRE.
In the classification of counties, there is a separate group for Oslo.
Name: Dental health care
Division for Health, care and social statistics
The statistics are presented on county level
Unrevised figures are published 15 th of March each year.
Preliminary figures are published 15 th of June each year.
Final figures are published as soon as the figures on municipal health and care statistics are final.
The collection of data, with the exception of the majority of personnel information and some population figures is done via KOSTRA once a year. The county dental officers fill in a form that is sent electronically to Statistics Norway.
Since the beginning of the 1970s, the Norwegian Board of Health has collected data about the dental health service. The collection of data from the county dental officers has been a part of KOSTRA (Municipality-State-Reporting) since it was implemented. As a result, Statistics Norway has collected data on dental health care services and the dental health of children since 2001. The collection includes information on scope, dental health results, personnel and finance data in the public dental health care. In addition, the statistics include information about personnel in the private dental health care.
The statistics provide information on counties and are used by organisations, researchers, media and the public in general. Furthermore, municipalities and counties, as well as government agencies such as the Ministry of Health and Care Services, the Directorate for Health and Social Affairs and the Norwegian Board of Health are important users of the statistics. The Norwegian Board of Health has the overall responsibility for the dental health care system, and uses the statistics in this work.
The Division for Labour Market Statistics in Statistics Norway publishes register-based employment statistics on all health and social work personnel. The information on personnel in private and public dental health care is based on the same data as the register-based employment statistics, called a-ordningen.

Lov om tannhelsetjenesten av 1. januar 1984 § 6-2, Statistikkloven av 16. juni 1989 § 2.2, samt Statistikklovens § 3-2 (Administrative registre)
The statistics cover public dental health care in Norway. Data concerning the scope of the public dental health care system, personnel and finance data, as well as children's dental health are collected. In addition, information about personnel in private dental health care is collected.
From 2015 onwards a new joint reporting solution called a-ordningen gathers the reporting from the employers to the Ee-register and some reports to the Tax Administration and Statistics Norway. The information on personnel in public and private dental health care is from 2015 onwards based on this new reporting solution. Employed persons are persons between 15-74 years of age who performed work for pay or profit for at least one hour in the reference week, or who were temporarily absent from work because of illness, holidays etc. Conscripts are classified as employed persons. Persons engaged by government measures to promote employment are also included if they receive wages. This follows recommendations from the International Labour Organization, ILO.
Statistics on the public dental health care system are mainly collected in KOSTRA form 43.
The total number of children aged 1-18 years and 3-18 years is taken from Statistics Norway's population statistics per 31.12. This also applies to youth aged 19-20 and the remaining adult population. This has been the procedure since 2001.
From 2007 onwards: the number of elderly, long-term ill and disabled people in home nursing per 31.12, and the number of elderly, long-term ill and disabled people in institutions is based on the IPLOS register. As of 2003: the number of elderly, long-term ill and disabled people in home nursing per 31.12 has been collected from the municipalities in KOSTRA form 6, while the number of elderly, long-term ill and disabled people in institutions has been collected from the municipalities in KOSTRA form 5.
From 2015 onwards: all information on personnel from public and private dental health care is collected from a-ordningen. Data on personnel not collected through registers include information concerning the number of dentist A man-years, and the number of vacancies in man-years per 31.12. These data are collected in KOSTRA form 43. Dentist A man-years are collected to keep track of the number of such man-years and are not part of any calculation of man-years in the statistics.
Register-based personnel information
The register based employment statistics was until the end of 2014 built on various public registers, the most important was the The Register of Employers and Employees, (Ee-register) produced by The Norwegian Labour and Welfare Organization (NAV). From 2015 onwards a new joint reporting solution called a-ordningen gathers the reporting from the employers to the Ee-register, produced by the Norwegian Labour and Welfare Administration, as well as some reports to the Tax Administration and Statistics Norway. A-ordningen is a coordinated digital collection of data on employment, income and tax deductions to the Tax Administration, the Norwegian Labour and Welfare Organization and Statistics Norway. This new joint collection provides Statistics Norway with information on wages and employed persons directly from a-meldingen, which is the electronic message containing all the information collected, rather than the multiple sources used until 2014. You can find more information about the new reporting at www.altinn.no/en/a-ordningen.
A-ordningen has replaced the Register of Employers and Employees and the Register of End of the Year Certificates (Register of Wage Sums). In addition to a-ordningen other registers provide additional information, the most important is the Register for Personal Tax Payers administered by the Directorate of Taxes, the Register of Conscripts from the Armed Forces Personnel and National Service Centre and The Central Coordinating Register for Legal Entities.
The registers mentioned above are still being used to assure the quality of the data, to consolidate the consistency between different data sources as well as choosing the right main job and to classify people as employed. A few additional registers are also being used for these purposes, where the ARENA-register produced by the Norwegian Labour and Welfare Organization is one example. It provides data on unemployed and people engaged in labour market projects.
This is a full count. It presents data on public dental health care in the counties, as well as on personnel in public and private dental health care.
Collection of data
The collection of data, with the exception of the majority of personnel information and some population figures (see 3.2), is done via KOSTRA once a year. The county dental officers fill in a form that is sent electronically to Statistics Norway. Statistics Norway carries out automated sum-controls and logical controls of the data reported in forms by the county dental officers. The controls are activated in the electronic forms as they are filled in and after they have been submitted. The data are compared with information submitted in previous years. The county dental officers are contacted if there is a lack of information, or when there are large discrepancies in the data on the basis of comparisons and evaluations. In such cases the county dental officers submit new data or give an explanation of the conditions related to the figures.
Register-based personnel information
A-ordningen: Statistics Norway receive monthly data from the Tax Administration Shared Services Agency (Etatens fellesforvaltning, EFF), a management entity of the Tax Administration, which administers a-ordningen on behalf of the three owner agencies; the Tax Administration, the Norwegian Labour and Welfare Organization and Statistics Norway.
The Register of Employers and Employees: Statistics Norway received weekly files on changes that occurred which NAV reported to Ee-register, in addition to an annual total report. From 2015 onwards, the Ee-register is replaced by a-ordningen.
The Register of End of the Year Certificates: A provisional extraction from the register was made in March, which formed the basis of the figures in the statistics. From 2015 onwards, the register is replaced by a-ordningen.
The Register for Personal Tax Payers: All information about the tax reporting and settlement is available electronically. Statistics Norway obtains an annual sample of the data from the Tax Directorate.
The register of civil workers and conscripts: Statistics Norway received quarterly files from Armed Forces Personnel and National Service Centre and The Norwegian State Administration Database at Dillingøy until the end of 2014. From 2015 onwards, these files are received monthly.
The Central Coordinating Register for Legal Entities: Variables like municipality of work and industry are collected from these registers.
For the two most important registers for the production from 2015 onwards, the control and revision is done in the following way:
Controls are carried out at several stages:
- Rules of business in the reception at The Tax Administration Shared Services Agency (EFF)
- In the production system for wages and employment at Statistics Norway
Rules of business (controls) in the reception at EFF:
A number of rules of business (controls) are being run to detect errors/omissions in the submitted information, after a-meldingen is received by EFF. Small to medium sized legal entities with a declaration obligation receives a feedback in a short amount of time (less than a minute). The larger legal entities have to wait a little longer for the feedback. The feedbacks from EFF include all uncovered discrepancies, where in the submitted information the discrepancies take place and what rule of business has been broken.
Controls in the production structure of Statistics Norway:
A number of checks and automatic actions are taking place during the production, the purpose is to ensure the quality of the data for statistical purposes. We distinguish between three types of controls:
- Automatic checks and actions
- Reports (monitoring)
- Manual checks
Checks that aim to uncover defects and discrepancies that should be corrected are mostly aimed at the employments. Several controls have uncovered errors and missing values concerning the number of hours in a full-time position and the percentage position, combined with other features like whether a job is a main job or second job, the contractual working hours and the payment arrangements.
Many registered employments are removed (not considered active) during the production because wage of the employment relation has not been registered in the reference month. This could apply to seasonal workers who have not performed any work in the reference month (and therefore not been paid), and where a date of termination of employment (wrongly) has not been reported, or in cases where individuals have mistakenly been reported with an active employment (e.g. temporary staff who has not been working during the given period).
The Register for Personal Tax Payers:
For the Register for Personal Tax Payers, a number of controls by machines are being run. Firstly the sum of partial records should match the main records from the Tax reporting. Further on, outliers are investigated to decide whether they are logical in relation to the rest of the Tax reporting. Internal consistency controls are also carried out.
The Register of Health Care Personnel, administered by the Directorate of Health and Social Affairs. This register gives an overview of all health care personnel licensed to practise their profession. Statistics Norway receives the status per 1 October for personnel licensed to practise. The register only contains educations for which state authorisation is required, and therefore does not contain information about all health care educations. People with a health care education who have not applied for a licence are not included. The register may also include people who have been granted a Norwegian licence, but who have not necessarily practised their profession in Norway.
Register of Educational Attainment of the Population (NUDB)
Statistics Norway's register of education is a supplement to the Register of Health Care Personnel. This register gives an overview of the highest education completed for all individuals resident in Norway per 1 October in the year before the statistics are produced.
The statistics are similar to the statistics formerly published by the Norwegian Board of Health. The statistics are therefore comparable with statistics published in the annual reports for the public dental health care.
From 2015 onwards the register based employment statistics will be based on a new data source for employees. Until the end of 2014, the main data source was the Employees register, produced by the Norwegian Labour and Welfare Organization. With the transition to the new data source, we will obtain more precise figures on the number of employed persons.
From 2002 – 2015: The use of register-based information for personnel data on private dental health care in 2002 means that these data are collected and defined in a different way than before. The figures are therefore not comparable with previous figures. This also applies to the use of register-based information in public dental health care from 2003. This means that the data are collected and defined in a different way than before and that the figures are not fully comparable with previous figures.
Oslo reported adult users of the emergency dental office as "adult paying clients" until 2003. This was changed from 2004, and there is a break in the time series for adult paying clients between 2003 and 2004. This also has implications on other calculations where figures for adult paying clients are used.
The quality of the statistics depends on correct information being submitted by the respondents. The control routines mean that we can detect the most obvious errors (see point 3.6). In addition there may be errors in the work process, such as punching errors, code errors etc. The statistics on public dental health care are assumed to have few errors as the county dental officers are in contact with the individual dental practice that reports the information. Furthermore, the data go through thorough control and revision routines at Statistics Norway.
