4 Introduction The 2009 Adult Dental Health Survey (ADHS) is the fifth in a series of national dental surveys that have been carried out every decade since The main purpose of these surveys has been to get a picture of the dental health of the adult population and how this has changed over time. The 2009 survey was commissioned by the NHS Information Centre for health and social care and was conducted on behalf of the Department of Health in England, the Welsh Assembly Health Department, and the Department of Health, Social Services and Public Safety in Northern Ireland. The survey was carried out in England, Wales, and Northern Ireland only: Scotland did not participate in the 2009 survey. Northern Ireland has participated in all of the ADH surveys since This report draws together the key clinical, behavioural and attitudinal dental estimates for Northern Ireland from the 2009 survey and also comments where possible on trends between 1979 and The overall sample size for the 2009 survey was 13,400 households, of which 750 were in Northern Ireland. Data collection for the survey took place between October 2009 and April 2010, and the final overall household interview response rate was 60 per cent. In Northern Ireland the household response rate was 69 per cent and a total of 719 individuals (including dentate and edentate adults) were interviewed. Of the dentate adults that were interviewed (n = 662) a total of 481 consented to the dental examination (consent rate 73 per cent) and 432 adults were actually examined (final examination conversion rate 65 per cent). The majority of Tables referenced in the subsections below can be viewed in the specific reports for the overall findings (for England, Wales and Northern Ireland). For example, in the section below on Function and Health the estimates for the rate of total tooth loss in Northern Ireland can be seen in Table in Oral health and function: a report from the Adult Dental Health Survey A compendium of additional tables are also presented in this report; while some estimates in these tables will be presented herein, there will be no discussion of these data by the variables with which they are crosstabulated including age, sex and socio-economic classification of the household. These additional tables are to be found at the back of the report. Full background and methodological details for the survey, can be found in Foundation report: Adult Dental Health Survey A glossary of all clinical terms can also be found in this report.

5 1 Oral health and function The proportion of adults who have retained some of their natural teeth is an important indicator of the oral health of a population. The majority of Tables referenced in the subsections below can be found in Oral health and function: a report from the Adult Dental Health Survey Natural Teeth In 2009, 93 per cent of all adults in Northern Ireland were dentate and 7 per cent were edentate. (Table and Table 1.1.1) Ninety-eight per cent of dentate adults had natural teeth in both arches, 1 per cent had teeth in the upper arch only and 1 per cent had teeth in the lower arch only. (Table 1.1.3) Number of natural teeth The average number of natural teeth of dentate adults in Northern Ireland is The majority of dentate adults in Northern Ireland (52 per cent) had between 27 and 32 teeth. (Table and Table 1.2.1) Eighty-five per cent of dentate adults in Northern Ireland have 21 or more natural teeth. (Table 1.2.2) Dentate adults in Northern Ireland had an average of 15.8 sound and untreated teeth and 15.7 sound, untreated teeth and roots (Tables and 1.2.4) Thirty-nine per cent of dentate adults in Northern Ireland have 18 or more sound and untreated teeth and 39 per cent have 18 or more sound and untreated teeth and roots. (Tables and 1.2.6) Periodontal health Fifteen per cent of dentate adults were classed as periodontally healthy (pocketing and loss of attachment less than 4mm) and had no calculus or bleeding; 41 per cent were periodontally healthy but had calculus and/or bleeding; and 44 per cent of dentate adults had loss of attachment and pocketing of 4mm or more. (Table 1.3.1) Excellent oral health Seven per cent of dentate adults had excellent oral health that is had 21 or more teeth, 18 or more sound and untreated teeth, no active decay at any site, no periodontal pocketing or loss of attachment above 4mm, and no plaque or calculus. (Table 1.4.1) Trends In 1979, 33 per cent of all adults in Northern Ireland were edentate, this fell to 18 per cent in 1988, 12 per cent in 1998 and 7 per cent in (Table ) Seventy-four per cent of adults aged 75 and over were edentate in 1979, this increased to 78 per cent in 1988, but fell to 60 per cent in In 2009, 50 per cent of adults aged 75 and over were edentate. (Table ) In 1979, dentate adults in Northern Ireland had 21.9 teeth on average; this increased to 25.1 in (Table ) Copyright 2011, The Health and Social Care Information Centre.

6 In 1979,13 per cent of dentate adults had 18 or more sound and untreated teeth; this increased to 39 per cent in (Table ) On average dentate adults in Northern Ireland had 11.4 sound and untreated teeth in 1979; this increased to 15.8 in (Table ) 2 Disease and related disorders The current distribution of obvious dental caries (decay), periodontal (gum) disease and tooth wear in Northern Ireland is presented along with some trends over time. The majority of Tables referenced in the subsections below can be found in Disease and related disorders: a report from the Adult Dental Health Survey Caries In Northern Ireland, 28 per cent of dentate adults had carious teeth (crowns and roots) in (Table 2.1.1) Dentate adults had a mean number of 0.7 carious teeth (crown and roots). (Table 2.1.3) Adults with at least one carious tooth had a mean number of 2.4 carious teeth. (Table 2.1.4) Twenty-seven per cent of dentate adults had primary or secondary caries. (Table 2.1.6) Amongst dentate adults, 20 cent had primary caries. Of these adults 12 per cent had one tooth with primary decay; 4 per cent had two teeth with primary decay; and 4 per cent had three or more teeth with primary decay. (Tables and ) Five per cent of dentate adults in Northern Ireland had secondary caries. Of these adults 3 per cent had one tooth with secondary decay, and 1 per cent had two or more teeth with secondary decay. (Tables and ) Five per cent of dentate adults had roots with active decay. (Table ) Periodontal condition Sixty-four per cent of dentate adults had bleeding; 38 per cent had pocketing of 4mm or more; 4 per cent had pocketing of 6mm or more. (Table and Table 2.2.1) Sixty-one per cent of dentate adults aged 55 years and over had loss of attachment (LOA) of 4mm or more; 16 per cent had LOA of 6mm or more; and 2 per cent had LOA of 9mm or more. (Table 2.2.5) Tooth wear Eighty-eight per cent of dentate adults had some wear in their anterior teeth; 15 per cent had some moderate wear; and 2 per cent had some severe wear on their anterior teeth. (Table 2.3.1) Trends Forty-eight per cent of dentate adults in Northern Ireland had periodontal pocketing of 4mm or more in 1998; this had fallen to 38 per cent in (Table ) Copyright 2011, The Health and Social Care Information Centre.

7 In 1998, 4 per cent of dentate adults in Northern Ireland had periodontal pocketing of 6mm or more; this remained unchanged in (Table ) Seventy-three per cent of dentate adults had wear on their anterior teeth in 1998, compared with 88 per cent in 2009; 9 per cent of dentate adults had moderate wear on their anterior teeth in 1998 compared with 15 per cent in 2009; and 1 per cent of dentate adults had severe wear on their anterior teeth in 1998 compared with 2 per cent in (Table ) 3 Urgent conditions Urgent conditions including dental pain, open dental pulps and oral sepsis, and untreated teeth with extensive decay, are an important and sometimes dominant factor in dental behaviour, and the prevalence and distribution of these conditions needs to be measured alongside estimates of the current state of adult dental health. The majority of Tables referenced in the subsections below can be found in Urgent conditions: a report from the Adult Dental health Survey Pain Nine per cent of dentate adults in Northern Ireland reported feeling current pain related to their teeth. (Table 3.1.1) Seventy-five per cent of dentate adults reported never or hardly ever feeling dental pain in the previous 12 months; 18 per cent reported feeling dental pain occasionally; and 7 per cent reported feeling dental pain fairly or very often. (Table 3.1.4) PUFA is a recently developed index of clinical consequences of untreated dental caries. It provides a measure of badly diseased and broken down teeth which have been attacked by dental decay and are causing significant problems in need of early attention. PUFA relates to open pulp, ulceration, fistula and abscess. Six per cent of dentate adults had at least one PUFA symptom. Three per cent of dentate adults had open pulp, 1 per cent had ulceration and 2 per cent had a fistula or abscess. (Table 3.2.1) Condition of teeth Ten per cent of dentate adults had one or more teeth with unrestorable caries. (Table 3.3.1) Urgent conditions Overall, 78 per cent of dentate adults had no urgent conditions; 15 per cent of had one urgent problem; 4 per cent had two urgent conditions; 2 per cent had three urgent conditions; and less than half of one per cent had four urgent conditions. (Table 3.4.1) 4 Complexity and maintenance The estimates presented below focus on the oral health of people in Northern Ireland by measuring the extent of the accumulated effects of restorative treatment and where these effects fall in the population. The majority of Tables referenced in the subsections below can Copyright 2011, The Health and Social Care Information Centre. All Rights Reserved. 7

8 be found in Complexity and maintenance: a report from the Adult Dental Health Survey Fillings and Crowns Ninety-one per cent of dentate adults had one or more fillings (crown and root surfaces). (Table 4.1.1) Adults with at least one filling had 8.7 filled teeth and 19.8 filled surfaces on average. The ratio of filled surfaces per filled tooth was 2.2. (Table 4.1.2) Thirty-one per cent of dentate adults in Northern Ireland had one or more crowns. (Table 4.1.5) Adults with crowns had 2.5 crowns on average. (Table 4.1.7) Restored teeth and surfaces In 2009, 92 per cent of dentate adults in Northern Ireland had one or more restored teeth. (Table 4.2.1) These adults had, on average, 9.7 restored teeth and 24.1 restored surfaces. (Table 4.2.) Five per cent of adults with one or more restored teeth had restorations with secondary decay (including roots); 21 per cent had unsound restorations (including roots). (Table 4.2.6) Denture use Overall, 80 per cent of all adults had natural teeth only; 13 per cent had natural teeth and dentures; 7 per cent were edentate with dentures; and less than half of one per cent were edentate with no dentures. (Table 4.4.1) Ninety-one per cent of dentate adults had natural teeth only; 6 per cent had a partial denture in one arch; 1 per cent had partial dentures in both arches; 1 per cent had a complete denture in one arch and a partial denture in the other arch; and 2 per cent had a complete denture in one arch only. (Table 4.4.2) Six per cent of dentate adults had at least one dental bridge. (Table 4.4.3) One per cent of dentate adults had at least one dental implant. (Table 4.4.5) Complexity In order to establish the complexity of dental treatment required eight indicators have been identified reflecting previous treatment or current disease. Four of the criteria are related to disease, three to existing restorative treatment load and one to reported problems impacting on daily life. During the oral examination each ADHS respondent was given a score based on these indicators. Individually none of these may present a particular clinical challenge, but in combination they may. In 2009, 41 per cent of dentate adults had a complexity score of zero; 25 per cent had a complexity score of one; 15 per cent had a complexity score of two; 12 per cent had a complexity score of three; 5 per cent had a complexity score of four; and 3 per cent had a complexity score of five or more.

9 Trends In 1979, dentate adults in Northern Ireland had 8.4 restored and otherwise sound teeth on average; this increased to 8.9 in Utilising the revised 1998 criteria the average number of restored but otherwise sound teeth in 1998 was 9.0 in 2009 this had decreased to 8.4 teeth (age unadjusted). (Table ) In 1979, the average number of restored but otherwise sound teeth for adults aged 16 to 24 was 9.5 teeth compared with 3.9 in 2009 (age unadjusted). (Table ) 5 Preventive behaviour and risks to oral health Good oral hygiene helps prevent dental problems such as the accumulation of plaque and calculus, which contribute to the development of gum disease and tooth decay. Daily preventive care including brushing is essential and will help stop dental problems before they develop. The majority of Tables referenced in the subsections below can be found in Preventive behaviour and risks to oral health: a report from the Adult Dental Health Survey Oral hygiene Seventy-five per cent of dentate adults said that they cleaned their teeth twice a day or more and 22 per cent said that they did once a day. Three per cent of dentate adults said that they cleaned their teeth less than once a day and less than half of one per cent said they never cleaned their teeth. (Table and Table 5.1.1) Seventy-seven per cent of dentate adults in Northern Ireland used toothpaste with a fluoride content of ppm, 19 per cent used toothpaste with a fluoride content of ppm and 4 per cent used toothpaste with a fluoride content of 550ppm or less. (Table 5.1.3) Fifty-two per cent of dentate adults in Northern Ireland use a toothbrush and toothpaste and 48 per cent use other dental products. Thirty-one per cent of dentate adults reported using mouthwash, 14 per cent reported using an electric toothbrush and 17 per cent reported using dental floss. (Table 5.1.5) Overall, 77 per cent of dentate adults reported that they had been given advice on brushing their teeth from a member of a dental team. (Table 5.1.7) Risks to dental health In 2009, 25 per cent of all adults in Northern Ireland indicated that they smoke. Twenty-six per cent of dentate adults said that they were current smokers. (Tables and and Tables and 5.2.2) Over half of dentate adults in Northern Ireland (54 per cent) were classified as having a high sugar intake that is they consume cakes, puddings, biscuits, pastries, sweets, chocolate or fizzy drinks six times a week or more. (Table and Table 5.2.4) Visible plaque Fifty-one per cent of dentate adults in Northern Ireland had visible plaque. The average number of teeth with visible plaque amongst dentate adults was 4.0, and the average percentage of teeth with visible plaque was 16 per cent.

10 Sixty-six per cent of dentate adults in Northern Ireland had calculus and the average number of sextants with calculus was 1.8. (Table and Table ) Trends In 1988, 69 per cent of dentate adults in Northern Ireland said that they cleaned their teeth at least twice a day, this rose to 72 per cent in 1998 and to 75 per cent in In 1988, 22 per cent of dentate adults said that they cleaned their teeth once a day; this has remained constant. (Table ) Seventy-seven per cent of dentate adults in Northern Ireland used just an ordinary toothbrush and toothpaste to care for their teeth in 1988, this fell to 53 per cent in 1998 and to 52 per cent in Mouthwash was used by 13 per cent of dentate adults in 1988, this rose to 23 per cent in 1998 and 31 per cent in The use of dental floss increased from 8 per cent in 1988 to 24 per cent in 1998, but fell to 17 per cent in (Table ) Fifty-seven per cent of dentate adults reported receiving dental hygiene advice from a member of a dental team in 1998; in 2009 this had increased to 77 per cent. (Table ) In 1998, 66 per cent of dentate adults in Northern Ireland had visible plaque compared with 51 per cent in The mean number of teeth with visible plaque has decreased from 5.4 in 1998 to 4.0 in (Table ) The average percentage of teeth with visible plaque in 1998 was 22 per cent compared with 16 per cent in (Table ) 6 Service considerations This estimates presented below illustrate adults in Northern Ireland use of and interactions with all types of dental health services. The majority of Tables referenced in the subsections below can be found in Service considerations: a report from the Adult Dental Health Survey Dental attendance Sixty per cent of dentate adults in Northern Ireland reported attending the dentist for regular check-ups; 9 per cent reported attending occasionally; 29 per cent reported attending only when they had trouble with their teeth. Two per cent of adults said that they had never attended the dentist. (Table and Table 6.1.1) Fifty-four per cent of dentate adults reported attending the dentist at least every six months; 18 per cent said that they attended every year; 5 per cent said that they went every two years, 6 per cent reported attending less frequently than this; and 17 per cent reported only attending when they had trouble with their teeth. (Table 6.1.4) Overall, 77 per cent of dentate adults in Northern Ireland indicated that they attended the dentist at least every two years. (Table 6.1.5) Fifty-six per cent of dentate adults reported their current dental attendance was about the same as it was five years ago; 20 per cent reported they went more often; and 23 per cent reported they attended less often than they did five years ago. (Table 6.1.6) Fifty-nine per cent of dentate adults reported their last dental visit was six months prior to the survey interview; 15 per cent visited seven to twelve months prior to interview; and 10 per cent between 12 months and two years prior to interview.

11 Overall 84 per cent of dentate adults reported they last visited their dentist within the previous two years. (Tables and 6.1.8) Dental service Sixteen per cent of dentate adults received private dental care at their last completed course of dental treatment; 52 per cent paid for NHS care; and 29 per cent received free NHS dental care. Overall 81 per cent of dentate adults received either paid for or free NHS dental care. (Table 6.2.1) Thirty-nine per cent of dentate adults in Northern Ireland paid nothing towards the cost of their last course of dental treatment; 21 per cent paid between 1 and 20; 17 per cent paid between 21 and 50; 11 per cent between 51 and 100; 6 per cent paid between 101 and 200; 4 per cent paid between 201 and 500; and 2 per cent paid over 501. (Table 6.2.2) Nine per cent of dentate adults indicated that they had a dental insurance plan. (Table 6.2.3) Dentate adults who had NHS treatment at their last course of completed treatment were asked why they chose NHS treatment; 57 per cent cited affordability; 25 per cent cited location of the practice; 13 per cent reported it was because of the reputation of the dentist; and 7 per cent reported that their dentist only sees NHS patients. (Table 6.2.4) Dentate adults who had private dental care during their last course of dental treatment were asked why they chose private care. Fifty-three per cent of adults said they used private dental care because their NHS dentist had gone private; 36 per cent said they were unable to find an NHS dentist; 11 per cent cited location of practice; and 10 per cent cited better quality of care. (Table 6.2.5) Dentate adults that had private dental care during their last course of dental treatment were asked what would encourage them to use the NHS. Forty-six per cent said having an NHS dentist in their area would encourage them to access the NHS; 25 per cent said nothing would encourage them to use the NHS; and 18 per cent said they would access NHS dental care if it was in a more convenient location. (Table 6.2.6) Forty-eight per cent of dentate adults in Northern Ireland said that they did not attend the dentist in the last two years because they felt there was nothing wrong with their teeth and so they had no need to go. Being afraid to go to the dentist and not seeing the point in going was given as a reason for non-attendance by 25 per cent of dentate adults. Nineteen per cent of dentate adults said they had not been to the dentist in the last two years because of a previous bad experience. (Table 6.2.7) Treatment Fifty-five per cent of dentate adults in Northern Ireland completed their last course of treatment in one visit; 45 per cent of adults that needed more than one visit. (Table 6.3.1) Eighty-eight per cent of dentate adults in Northern Ireland had a check-up at their last course of treatment; 58 per cent had their teeth scaled and polished; 45 per cent had a tooth filled; and 41 per cent had an X-ray. Forty-two per cent of dentate adults received advice on looking after their teeth during their last course of treatment. (Table 6.3.4) Sixty-five per cent of dentate adults in Northern Ireland rated their last completed course of treatment as good or very good value for money; 18 per cent of adults rated Copyright 2011, The Health and Social Care Information Centre.

12 the cost of their last course of dental treatment as fair; and 17 per cent rated it is poor or very poor value for money. (Table 6.3.6) Ninety-one per cent of adults in Northern Ireland reported having a filling during the course of their lifetime; 82 per cent have had a tooth extracted (other than their wisdom teeth); 77 per cent have received a scale and polish; and 44 per cent have had a wisdom tooth extracted. (Table ) Dental practice Ninety-two per cent of adults in Northern Ireland had visited the dental practice before their most recent visit; for 8 per cent of adults their most recent visit to their dental practice had been their first one to that practice.

(Table 6.4.2) Trends In 1988, 42 per cent of dentate adults in Northern Ireland reported that they attended the dentist for a regular check up; this had risen to 51 per cent in 1998; and to 60 per cent in (Table ) Sixty-two per cent of dentate adults in 1998 received a scale and polish during their last course of treatment compared with 58 per cent in 2009; 41 per cent of adults had a tooth filled in 1998 compared with 45 per cent in (Table ) 7 Outcome and impact The subjective perceptions of respondents in relation to their general health, oral health and quality of life are important factors to understand, especially as they give a non-clinical indication of the potential demand for dental services and treatment. The majority of Tables referenced in the subsections below can be found in Outcome and impact: a report from the Adult Dental Health Survey Self-rated general and dental health Eighty-six per cent of dentate adults in Northern Ireland reported that they had good/very good general health and 74 per cent rated their dental health as being good/very good. (Table 7.1.2) Oral Health Impact Profile (OHIP-14) Twenty-five per cent of dentate adults reported experiencing physical pain occasionally or more often as a result of oral health conditions, and 17 per cent experienced psychological discomfort. Thirty-two per cent of dentate adults reported experiencing at least one problem concerning their oral health. (Table 7.2.6) Copyright 2011, The Health and Social Care Information Centre.

13 Oral Impact on Daily Performance (OIDP) Twenty-eight per cent of all dentate adults in Northern Ireland reported having difficulty with at least one item on the OIDP scale. Sixteen per cent of all dentate adults reported a degree of difficulty with eating because of oral health problems and 14 per cent reported difficulties when smiling or showing their teeth. (Table ) The vast majority (72 per cent) of dentate adults in Northern Ireland had no oral impacts as measured by the OIDP scale however, the mean total OIDP score was 3.9. Six per cent reported one problem; 7 per cent reported two problems; 8 per cent reported three problems; 4 per cent reported four problems; and 4 per cent reported five problems. (Table ) Of those dentate adults that reported a problem that impacted on their daily performance 22 per cent reported one problem; 24 per cent reported two problems; 27 per cent reported three problems; 13 per cent reported four problems; and 14 per cent reported five problems. The mean total score OIDP score was (Table ) Trends Fifty-four per cent of dentate adults reported no problems on the OHIP scale in 1998, compared with 68 per cent in (Table ) In 2009, a quarter (25 per cent) of dentate adults reported feeling physical pain occasionally or more often in the previous 12 months, this has fallen from 35 per cent in Twenty-three per cent of dentate adults in 1998 reported feeling psychological discomfort compared with 17 per cent in (Table ) 8 Access and barriers to care The estimates below illustrate the experience of adults in Northern Ireland in accessing NHS dental care and explores some of the barriers to access. In addition estimates of the levels of anxiety among adults in Northern Ireland, who have ever been to a dentist, are also presented. The majority of Tables referenced in the subsections below can be found in Access and barriers to care: a report from the Adult Dental Health Survey Access to care Sixty-four per cent of all adults in Northern Ireland had tried to make an NHS appointment in the last three years. (Table 8.1.1) Of those who tried to make an NHS appointment in the previous three years 91 per cent were successful and attended this appointment; a further 1 per cent successfully made an appointment but did not attend. Seven per cent were unable to make an appointment. (Table 8.1.4) Ninety-three per cent of adults in Northern Ireland who tried successfully made an NHS appointment for themselves in the previous three years already had an NHS dentist when they tried to make this appointment. Five per cent of adults were able to make an appointment with the first NHS dentist they tried; a small minority (between 1 per cent and 2 percent) had to make at least two (but in some cases more than five) visits or phone calls before they obtained an appointment.

15 Tables Presentation of data o o o o o Figures are rounded to the nearest whole value. This could have an impact on row or column percentages which may add to 99 per cent or 101 per cent. Where 0 per cent is shown in a table, this indicates that fewer than 0.5 per cent of people gave this answer. Instances where no answers for a particular response were given are indicated in the tables by '-'. A few respondents did not answer some questions. These no answers have been excluded from the analysis. Tables that describe the same population have slightly varying bases. The individual figures for unweighted sample sizes are rounded to the nearest 10 cases and may not add up to the figures shown in the totals. Small bases are associated with relatively high sampling errors and this affects the reliability of estimates. In general, percentage distribution is shown if the base is 30 or more.
