Service mix in general dental practices employing and not employing dental hygienists

Abstract Service mix studies conducted in Australia have indicated a low provision of periodontal services. The service mix in Australian general dental practices employing dental hygienists has not been studied. This study compares the service mix between 18 practices employing hygienists and 29 practices not employing hygienists in Adelaide. Practices employing hygienists tended to be larger group practices, with younger dentists seeing a younger set of patients. Practices employing dental hygienists provided a mean of 97.9 services to 57.2 patients over 2 days, significantly higher than the mean of 68.8 procedures to 39.1 patients in practices not employing dental hygienists. Comparing the % of procedures provided in treatment categories as a ratio of total procedures, practices employing dental hygienists provided significantly more periodontal procedures and less oral surgery, prosthetic and restorative procedures. Periodontally-related services accounted for an average of 37.7% of procedures in practices employing dental hygienists compared with 18.9% in practices not employing dental hygienists (p(0.05). Periodontal and preventive treatment of 50.7%) of patients in practices employing hygienists was delegated to a hygienist, and the level of delegation of periodontally-related procedures was 77.2%. Over 90% of procedures performed by hygienists were periodontally-related, with the removal of subgingival calculus accounting for 57.7% of all procedures provided by dental hygienists. In conclusion, practices employing hygienists had a more periodontally-orientated service mix, with hygienists acting to complement the services of dentists in the provision of periodontal services, rather than as a substitute for the dentist.     

Hygienist employment and the presence of periodontal notations in general dental practice patient records

Available data suggest that the provision of periodontal ly related services in general dental practices is low. However, studies indicate that the employment of dental hygienists is associated with increased provision. One method of measuring is by examination of notations in patient treatment records. As part of a project assessing the effectiveness of professional education in changing the provision of periodontal services, 2280 records, comprising 60 randomly selected records of dentate adult patients who had received a dental examination in the previous 6 months were audited in each of 38 practices, 13 of which employed hygienists. Entries of a periodontal nature were classified under 3 categories: diagnostic, preventive and treatment. The presence or absence of each item on each record was recorded. Diagnostic services were notated infrequently overall, but practices employing hygienists had a significantly lower number of records with no diagnostic notations. Preventive items were more frequently notated in practices employing hygienists. Treatment items were most frequently notated in both types of practices. Overall, 13 of the 23 items were recorded significantly more frequently in practices employing hygienists.     

Evaluating and influencing periodontal diagnostic and treatment behaviors in general practice

Providers' periodontal diagnostic and treatment behaviors were assessed in 34 practices in two North Carolina counties. Regularly attending patients had a low prevalence of gingival pocketing on index teeth, moderate attachment loss, and fairly prevalent bleeding and calculus. Treatment frequency and patient knowledge were generally adequate, but the notation of periodontal status in the patient record was insufficient. A continuing education intervention resulted in substantial and significant improvement in notation rates. Changes in rates with which services were provided, and changes in patient periodontal status were smaller and mixed. The study shows that continuing education can be effective in helping some but not all providers adopt needed, appropriate behaviors.     

Korean dental hygienists' knowledge and opinions about etiology and prevention of dental caries

Objectives: Because of their formal education Korean dental hygienists have the potential to be the primary source of information on caries prevention for patients and the general public, and inuence the use and adoption of caries preventive procedures. The purposes of this study were to determine the knowledge and opinions about caries etiology and prevention among Korean dental hygienists, and to describe associated factors. Methods: A pre-tested, 20-item questionnaire was mailed to 1120 dental hygienists selected by stratied d random sampling and allocated proportionately. A postcard reminder was sent to all dental hygienists after 1 week. Non-respondents were sent additional complete mailings after 3 and 7 weeks. The response rate was 77% (n=863). Results: Analysis of six factors thought to be related to knowledge about caries etiology and prevention showed that dental hygienists who were taught to provide oral health education and believe that it is desirable to practice oral health education during dental hygiene school and those employed in health centers were likely to be more knowledgeable about caries etiology and prevention than other hygienists (P < 0.05). In regression analysis of the perceived effectiveness of caries preventive procedures, hygienists who provided oral health education during their formal training tended to rate caries preventive procedures as being more effective than other dental hygienists (P < 0.05). Conclusions: Overall, the results of this study suggest that most dental hygienists do not have up-to-date information on the etiology and prevention of dental caries, mechanisms of action ofuoride e and effectiveness of preventive procedures. Efforts to increase the level of knowledge of Korean dental hygienists about caries prevention should focus on strategies to educate dental hygienists who have not been taught to provide oral health education, who do not have favorable opinions about the desirability of oral health education, and who had no experience with providing oral health education as part of their work, especially hygienists working in private clinics. Further, these efforts should include the revision of dental hygiene curricula and continuing education courses.     

A comparison of patients attending general dental practices employing or not employing dental hygienists

Previous studies have shown that dental practices employing dental hygienists provide a more periodontally oriented mix of dental services. Little is known about differences in the characteristics of patients who attend these practices, and whether these reflect the orientation of service delivery. In this study, a comparison was made between patients attending private general dental practices employing hygienists and patients attending practices without hygienists in Adelaide, South Australia. A questionnaire was mailed to 2391 patients, and valid responses were received from 632 patients attending 12 practices employing hygienists, and 1052 patients attending 22 practices not employing hygienists. Bivariate analysis of the responses comparing the two groups of patients was conducted using ANOVA for continuous variables and chi-square statistics for categorical variables. A multiple logistic regression model was developed to identify characteristics of patients attending practices with hygienists. Examination of significant (p<0.05) findings revealed that patients attending practices with hygienists had a higher socio-economic status, had a more preventive pattern of use of services, had better knowledge of periodontally related topics and it was more likely that the dental profession was their main source of information on these topics. These findings indicate that patient profiles do reflect the orientation of service delivery within dental practices and raise the question of whether the denial practice alters the patient's knowledge and behaviour or whether certain patients selectively seek care from practices with hygienists.     

Oral health in pregnancy: educational needs of dental professionals and office staff

Objective: Dental care during pregnancy is important for pregnant women and their children. Comprehensive guidelines for the provision of dental services for pregnant patients were published in 2006, but there is relatively little information about their use in actual practice. The aim of this study was to examine differences in knowledge and attitudes regarding dental care in pregnancy among dentists, dental hygienists, dental assistants, and nonclinical office staff. A secondary aim was to identify sources of influence on attitudes and knowledge regarding the guidelines. Methods: A survey was used to collect information from 766 employees of a Dental Care Organization based in Oregon; responses from 546 were included in the analyses reported here. Results: Statistically significant differences in knowledge were found among the professional‐role groups. Dentists and hygienists consistently answered more items correctly than did other respondents. Within all professional‐role groups, knowledge gaps existed and were most pronounced regarding provision of routine and emergency services. Positive perceptions of providing dental care during pregnancy were associated with higher knowledge scores (z = 4.16, P < 0.001). Conclusions: Updated dental education and continuing education for all dental office personnel are needed to promote the diffusion of current evidence‐based guidelines for dental care during pregnancy.     

Preventive Dentistry In Texas, Usa

This paper presents the results of a 1985 survey of 1000 Texas dentists regarding three major types of preventive measures--educational services, preventive procedures, and diagnostic services. The results show that among several given educational services, respondents tended most to instruct on correct brushing or flossing and tended least to counsel on diet. Among preventive procedures, most dentists removed plaque or calculus. A very small portion applied occlusal sealants on patients under the age of 15. As for diagnostic services, most performed oral cancer screening exams. Most performed dental X-rays, but many did not use leaded protection on their patients while taking X-rays. A large number did not check their patients' blood pressure. Income, attendance of continuing education programs, and number of dental hygienists were strong, positive predictors of provision of all three types of preventive measures. Dentists who practiced in more populous areas, or had practiced for fewer years, more likely provided patients with educational services and preventive procedures. Dentists delivered more preventive procedures if they attended more professional dental meetings. Dentists who worked more hours were more likely to provide educational services and preventive procedures. Patient load correlated negatively with dentists' delivery of preventive procedures.     

Adequacy of Oral Health Information for Patients with Diabetes

Objective: We investigated the perception of dental hygienists regarding their adequacy of providing diabetics with diabetes‐related oral health preventive education. Methods: A one‐page questionnaire printed on both sides was mailed to 2,237 licensed registered dental hygienists with a South Carolina (SC) mailing address. In addition to the dental hygienists' background and practice characteristics, their perception of adequacy for educating patients with diabetes on various diabetes‐related oral health topics and reasons for inadequate coverage of materials were queried in the survey. Results: After two follow‐up mailings, 995 completed and usable surveys were returned. An average of 93.6 percent of respondents indicated that they adequately covered topics of oral hygiene and general oral health issues. However, about 60 percent of respondents reported not covering all essential materials related to oral health when educating diabetic patients. The three most common reasons were: a) insufficient time (60.1 percent); b) patient disinterest (41.2 percent); and c) insufficient information on oral care and diabetes (39.7 percent). Respondents reporting insufficient information were less likely to adequately address the effect of periodontal disease on diabetes (P < 0.001), effect of uncontrolled diabetes on periodontal disease (P < 0.001), and dry mouth management (P = 0.03). Conclusion: This study indicates that SC dental hygienists do not routinely provide patient education on diabetes‐related oral health and healthy lifestyle topics. Lack of time, patient disinterest, and insufficient information were the three main reasons for respondents not covering these essentials. A practical method for improving dental hygienists' comprehensive service to patients with diabetes is to offer them more continuing education on diabetes and oral health to supplement their knowledge, skills, and confidence to educate this growing population.     

Dental Sealant Usage in Virginia

This trend study reports the results of a survey designed to determine usage of dental sealants in Virginia. A total of 2,434 general dentists, dental hygienists, and pedodontists were sent questionnaires regarding usage, technics, products, educational experience, and public interest in dental sealants. Increases in the provision of sealant coverage and in public interest for this preventive measure were noted. Approximately three-fourths of general dentists and dental hygienists working in a general or pedodontic practice are offering sealants to their patients. Pedodontists are the largest group of providers, with nearly 100 percent of pedodontists applying sealants. Recent graduates are applying sealants more often than earlier graduates. Preference for Delton clear color, light-cured material was shown. In general, a lack of professional knowledge about sealants continues to exist. Professional organizations and academic institutions may want to plan additional continuing education offerings for practitioners and to consider increased dental education instruction for students.

Rantanen M, Johansson K, Honkala E, Leino‐Kilpi H, Saarinen M, Salanterä S. Dental patient education: A survey from the perspective of dental hygienists. Abstract: Objectives: The aim of this study was to describe the current patient education practices of dental hygienists by exploring their views concerning their skills and knowledge related to patient education and by determining the implementation of patient education in their work, with regard to both method and content. Methods: The target group consisted of 416 dental hygienists (n = 222, 53%) The research strategy used was a survey. The material was gathered using questionnaire. Results: According to the dental hygienists, their skills and knowledge about patient education were good. However, the implementation of education was not in line with these assessments. The content of the education given focused mostly on the functional dimension. Little use was made of various educational methods, and the dental hygienists felt that they were not in good enough command of the methods. The patient’s expectations and learning were not assessed systematically. The education provided and the assessment of the need for education often focused on the professional him/herself and the standpoint of the patient empowerment was disregarded. Conclusions: These results lay the foundation for additional research aimed at developing the patient education given by these professionals and making it support the empowerment of each patient.     

The working practices and job satisfaction of dental hygienists in New Zealand

OBJECTIVES: To describe the current working practices and level of job satisfaction of dental hygienists in New Zealand. METHODS: Postal survey of all dental hygienists on the New Zealand Dental Council's database. An initial mailing was followed by a 3-week follow-up. Information was sought on respondents' demographic characteristics, current occupation and working practice, history of career breaks, continuing education and career satisfaction. RESULTS: 213 responses were received (73.2%); 90.6% were currently working as hygienists, mostly in private practice. Many worked part time, particularly those with children. Almost 50% of respondents had taken at least one career break, most frequently for childrearing. The mean time taken in career breaks was 3.6 years. Overall, dental hygienists reported high levels of satisfaction with their careers and their income. Older hygienists had higher career satisfaction scores. Most respondents were actively involved in continuing education. Almost half were interested in expanding the range of procedures they perform. Over one-third plan to retire within the next 10 years. CONCLUSIONS: While many hygienists take career breaks and work part time, most have a high level of career satisfaction, actively participate in continuing education, and are satisfied with their remuneration.     

Utilizing dental hygienists to undertake dental examination and referral in residential aged care facilities

Hopcraft MS, Morgan MV, Satur JG, Wright FAC. Utilizing dental hygienists to undertake dental examination and referral in residential aged care facilities. Community Dent Oral Epidemiol 2011; 39: 378–384. © 2011 John Wiley & Sons A/S Abstract – Objective: The Australian population is ageing, and a growing proportion of elderly Australians are now living in residential aged care facilities (RACFs). These residents are commonly dependent on others for their daily oral hygiene care and often display high levels of plaque and calculus. With declining edentulism rates, periodontal disease is becoming more prevalent in this population. The aim of this study was to investigate the ability of a dental hygienist to undertake a dental examination for residents of aged care facilities, devise a periodontal and preventive treatment plan and refer patients appropriately to a dentist. Methods: A total of 510 residents from 31 Victorian RACFs were examined, with 275 dentate residents included in this study. Between May 2005 and June 2006, residents were examined by a single experienced dental epidemiologist and one of four dental hygienists using a plane mouth mirror and periodontal probe. Results: A total of 510 residents from 31 RACFs had a dental examination from a dentist and one of four dental hygienists. The treatment needs of residents examined were high, with nearly all of the 275 dentate residents requiring preventive and periodontal treatment, and three‐quarters requiring referral to a dentist for treatment. There was excellent agreement between the dentist and hygienists regarding the decision to refer residents to a dentist for treatment, with high sensitivity (99.6%) and specificity (82.9%). Only 8.0% of residents were referred by a hygienist to a dentist when the dentist considered that no referral was required. Conclusions: Dental hygienists have the skills and knowledge necessary for undertaking a dental examination for residents, correctly identifying the majority of residents who require a referral to a dentist. They are capable of formulating appropriate dental hygiene treatment plans for residents of aged care facilities. It is recommended that there should be greater utilization of hygienists in the provision of dental care to residents of aged care facilities, as a safe, efficient and effective use of health resources.     

Dental hygienists in Europe: trends towards harmonization of education and practice since 2003

Abstract: Aim: The aim of this study was to investigate the trends in dental hygienists’ education and regulation in the European Union (EU) and European Economic Area (EEA) to examine whether, since 2003, there has been harmonization in dental hygiene education. Methods: Information and data were obtained via piloted questionnaires and structured interviews with delegates from the International and European Dental Hygienists’ Federations and representatives of the Council of European Chief Dental Officers and by literature review. Results: In the EU/EEA, dental hygienists are legally recognized in 22 countries. Since 2003, there has been an increase in the number of Bachelor degree programmes and in autonomous practice. Entry to the profession is now exclusively via a Bachelor degree in five EU/EEA Member States and pending in two more. Ten Member States have adapted their degree programmes to the European Credit Transfer System. Two Member States combine education for dental hygienists and dental therapists. However, dental hygienists are not recognized by EU law and in five Members States, the introduction of the profession has been opposed by dental associations. Conclusions: For the reasons of wide variations in the standards of preventive care and periodontal therapies, the formal recognition of the dental hygiene profession by EU legislation and agreement on a pan‐European curriculum for dental hygiene education leading to defined professional competencies and learning outcomes is required. To achieve this, there is a need for a better collaboration between competent authorities including governments, universities and dental and dental hygienists’ associations.     

Recall intervals, dental hygienists and quality in child dental care

Abstract Decline in dental disease and the need to provide dental care efficiently suggest changes in clinical and administrative routines in public dental care provision for children. A field project in Norway demonstrated productivity gains after the introduction of individualized recall intervals and using dental hygienists to conduct recall examinations. The purpose of the present study was to assess changes in the quality of dental health outcome and changes in the quality of the process of dental care provision. Recall intervals were increased from a target of 12 months to 16 and 18 months in two districts. Dental hygienists undertook all recall examinations and referred to dentists those patients who required operative care. Bitewing radiographs were inspected for all 18-yr-olds who were examined in 1989, 1990 and 1991 (n=956) and for those who were examined before the changes were implemented in 1987 (n=300). For each child, approximal caries on 24 surfaces was scored according to a 4-point severity scale. Clinical records were examined to determine what treatment had been provided. For each year after the changes were implemented, the quality of health outcome was assessed by comparing the radiographic caries prevalence and the number of sound surfaces with 1987 data. Quality in the process of care provision was indicated by the treatment decisions for approximal caries and by the proportion of uninterpretable surfaces on radiographs for each study year. The mean number of sound surfaces increased over time. A declining proportion of sound surfaces was restored over the study period, and almost all caries lesions extending deep into dentine were restored. Radiographic quality improved during the project period. The overall finding was that the changes to clinical and administrative routines were not associated with major changes in the quality of care provided in the short run.     

Dental hygienists-independent practice and pain control services

Abstract – In 1990, 78 dental hygienists who were members of the Dutch Dental Hygiene Association and working in an independent practice received a questionnaire (response rate: 79%) about the administration of local anesthesia. The main aim of this study was to dertermine the need for this service prior to deep scaling. The results of the survey showed that the need to administer local anesthesia for this purpose is limited in spite of the large number of patients with periodontal problems treated in independent dental hygiene practices. In most circumstances the cooperation with the dentist is satisfactory. However, 83% of the respondents indicate a limitation in the pain control services.     

Working practices and job satisfaction of Victorian dental hygienists

BACKGROUND: Increasing demand for dental services and a projected shortage in the oral health workforce in Victoria has focused attention on dental hygienists as one mechanism for increasing the supply of dental services. Understanding the dental hygienist workforce is essential in order to plan effectively for the future delivery of dental services in Victoria. METHODS: A postal survey of a random sample of Victorian dental hygienists was undertaken in 2006. Data on hygienists' demographic characteristics, current dental practice, history of career breaks, aspects of clinical practice and job satisfaction were collected. RESULTS: A response rate of 77 per cent was achieved. A total of 94.0 per cent of hygienists were currently working as a dental hygienist, working an average of 28.7 hours per week. Younger hygienists worked longer hours than their older colleagues. Career breaks were common, with 44.8 per cent reporting a career break of greater than one month, predominantly for child rearing, with a mean career break of 20.1 months. Hygienists reported a high level of satisfaction with most aspects of their employment. CONCLUSIONS: Victorian hygienists worked predominantly in private practices in metropolitan Melbourne, providing a range of preventive and periodontal services. Understanding the working patterns of dental hygienists is critical as hygienist numbers expand in the future, in order to undertake thorough evidence-based workforce planning.     

The effects of professional oral health care on patients in the subacute stage of emergent neurosurgical disorders

This study evaluated the effectiveness of professional oral health care (POHC) on patients who were in the subacute stage of neurosurgical disorders. Forty subjects (26 male, 14 female) with acute cerebrovascular disorders or neurotrauma were randomly divided into two groups. The intervention group (n = 21) received POHC treatment by dental hygienists, and the control group (n = 19) did not. To evaluate the change in oral health status of the subjects, an oral examination was carried out at baseline and four weeks later. For the subjects in the intervention group, periodontal condition, oral hygiene status, and oral function improved statistically significantly. The detection rate for methicillin‐resistant Staphylococcus aureus (MRSA) was statistically significantly lower in the intervention group than in the control group. These results suggest that POHC performed by dental hygienists in collaboration with nurses plays an important role in the promotion not only of oral health but also of general health.     

The relation of preventive dental behaviors to periodontal health status

Abstract Current recommendations for periodontal health maintenance emphasize toothbrushing, flossing and periodic dental checkups. The purposes of this study were to examine (1) the effects of these practices on periodontal health and (2) the relationships of demographic and socioeconomic variables with these behaviors and with periodontal health. Adults (n= 319) in the Detroit, Michigan tri-county area were asked how frequently they performed the 3 preventive behaviors. Levels of plaque, gingivitis, calculus, and periodontal attachment were then assessed during in-home dental examinations. There were no statistically significant differences in these health measures between those with acceptable and unacceptable brushing behavior. About 20% of the subjects reported acceptable flossing behavior, and these individuals had significantly less plaque and calculus than other participants. Over 3/4 of subjects reported having a dental checkup at least 1 × a year, and these persons were found to have significantly less plaque, gingivitis, and calculus compared to less frequent attenders. Acceptable brushing behavior was not associated with any particular demographic or socio-economic characteristic, while differences in acceptable flossing behavior were found among age groups. Frequencies of yearly dental checkups varied significantly within every demographic and socioeconomic characteristic.     

Caries preventive methods in child dental care reported by dental hygienists, Norway, 1995 and 2004

Dental hygienists are used as first-line personnel in child dental care in Norway, and have an increasing influence on the delivery of preventive dental services. The purpose of this study was to describe: (1) preventive methods reported by hygienists in child dental care in Norway and (2) changes in preventive care during the 9-year period 1995 to 2004. Questionnaires were sent to all dental hygienists in the public dental services in Norway in 1995 and 2004; 70% (199 of 286) were returned in 1995 and 71% (210 of 297) in 2004. The hygienists considered one-third of children to be at risk of caries and spent 45 min of preventive care on these children every 16th month, while the remaining children were given 15 min of prevention every 20th month. One-third of the hygienists provided fluoride varnish for all children and one-fourth placed sealants routinely. Ninety percent of the hygienists reported that all children were given information on diet, hygiene, and fluoride. Most of the preventive practices of dental hygienists reflected limited changes in the period 1995 to 2004. However, the hygienists had reduced the use of fluoride varnishes and less often recommended fluoride tablets. The majority of hygienists reported that they individualized clinical prevention, while individual oral health information was standardized and given to all children. The results indicate that in 2004 a preventive approach combining individual information for all with intensified clinical prevention for children considered at risk was followed in child dental care.
