Does dental undergraduate education and postgraduate training enable intention to provide inhalation sedation in primary dental care? A path analytical exploration.

AIM: To examine how quality standards of dental undergraduate education, postgraduate training and qualifications together with confidence and barriers could be utilised to predict intention to provide inhalation sedation. METHODS: All 202 dentists working within primary dental care in NHS Highland were invited to participate. The measures in the questionnaire survey included demographic information, undergraduate education and postgraduate qualifications, current provision and access to sedation service, attitudes towards confidence, barriers and intention to provide inhalation sedation. A path analytical approach was employed to investigate the fit of collected data to the proposed mediational model. RESULTS: One hundred and nine dentists who completed the entire questionnaire participated (response rate of 54%). Seventy-six per cent of dentists reported receiving lectures in conscious sedation during their undergraduate education. Statistically significantly more Public Dental Service dentists compared with General Dental Service (GDS) dentists had postgraduate qualification and Continuing Professional Development training experience in conscious sedation. Only twenty-four per cent of the participants stated that they provided inhalation sedation to their patients. The findings indicated that PDS dentists had higher attitudinal scores towards inhalation sedation than GDS practitioners. The proposed model showed an excellent level of fit. A multigroup comparison test confirmed that the level of association between confidence in providing inhalation sedation and intention varied by group (GDS vs. PDS respondents). Public Dental Service respondents who showed extensive postgraduate training experience in inhalation sedation were more confident and likely to provide this service. CONCLUSION: The quality standards of dental undergraduate education, postgraduate qualifications and training together with improved confidence predicted primary care dentists' intention to provide inhalation sedation.

Assessing sedation need and managing referred dentally anxious patients: is there a role for the Index of Sedation Need?

AIM: To conduct an exploratory investigation of public dental service (PDS) practitioners' planned sedation modality using a structural equation modelling approach, in order to identify the explanatory value of using the Index of Sedation Need (IOSN), or its component parts, to predict sedation modality in patients referred with dental anxiety. METHODS: A convenience sample of patients referred to the PDS for dental anxiety management was invited to take part. The IOSN was completed for each patient (patient dental anxiety, medical and behavioural indicators and dental treatment complexity) as well as the American Society of Anesthesiologists Physical Status Classification System and the Case Mix Tool. The practitioners completed details of their planned sedation modality and identified normative dental treatment need. The data were entered onto an SPSS v21 database and subjected to frequency distributions, t-tests, correlation analysis and exploratory partial structural equation modelling (SEM). RESULTS: Ninety-five percent of patients were ranked as MDAS 3 or 4, indicating high dental anxiety; 69% had a medical condition, which might impact on dental treatment and 82% had a dental treatment need, which was classified as intermediate/complex according to the IOSN. Eighty-eight percent of the patients in accordance with the IOSN required sedation: 62% of patients were assessed as requiring intravenous sedation. The IOSN discriminated between patients who were assessed as requiring more complex sedation modalities and had a greater normative treatment need. The SEM showed that the patient dental anxiety (P <0.02) and dental treatment complexity (P <0.02) predicted planned sedation modality. Functional morbidity was less strong, as a predictor, and was significant at the ten percent level. CONCLUSIONS: The IOSN is a useful and valid assessment of sedation need and predicted sedation modality for patients referred with high dental anxiety states and secondly, that component parts of the IOSN add explanatory value in practitioners' choice of planned sedation modality.
