Diagnoses and treatment proposals in periodontal treatment. A comparison between dentists, dental hygienists and undergraduate students.

The aim of this study is to find out how professionals in Swedish dental care perform diagnostic procedures in general. Is there a common ground between dentists and dental hygienists concerning sharing different job assignments in an effective way? Are the methods of treatment used in accordance with degree of severity of the disease and to what extent is proposed treatment in accordance with the National Guidelines? A questionnaire consisting of three different patient cases with periodontal disease was sent to 804 private practitioners, 809 dentists in Dental Public Service, 802 dental hygienists and 40 dental students on their final semester at the Dental School in Malmo. The questionnaire was completed by 1,103 respondents (47%). A majority of all practitioner groups (94%) found that a relatively healthy patient had disease, the risk for developing further disease was deemed none too low by 97%, but 91% wanted to give preventive care. A vast majority suggested more dental care to healthy patients as compared to patients with severe periodontal disease. In Conclusion the two groups, i.e. dentists and dental hygienists, did not to a sufficiently high degree share views on diagnosis and treatment, in order to optimize the resources in dentistry. The delivery of dental care was not in line with the severity of disease and too much attention was paid to the needs of relatively healthy persons. To change this pattern, the incentives in and structure of the national assurance system could be adapted. Furthermore, the knowledge basis for periodontal diagnosis and treatment needs, with special reference to the National Guidelines, should to a higher degree be shared by all caregivers.
