Two audits of the diagnosis of oral cancer and the two-week rule following referrals from primary care practitioners in Newcastle.

AIM: The aim of the two audits was to evaluate the success of the two-week rule in the oral and maxillofacial surgery (OMFS) department at the Newcastle General Hospital (NGH) and then subsequently in the oral surgery and oral medicine departments at Newcastle Dental Hospital (NDH). METHODS: All two-week referrals seen at the NGH over a one-year period were examined retrospectively. An identical subsequent audit was carried out at the NDH over a second one-year period, also retrospectively. RESULTS: In the initial audit at the NGH, a total of 63 two-week referrals were received during the one-year period analysed. Of these, 57 (90%) were seen within the appropriate time period, and 60 (95%) conformed to the Department of Health guidelines. Seven (11%) of the 63 referred patients were diagnosed with head and neck cancer, indicating a positive oncology detection rate of 11%.In the later audit at the NDH, 49 urgent referrals were assessed. Forty-three of the 49 referrals (88%) were seen within the appropriate time period and thirty-nine (80%) were compliant with the referring guidelines. Forty-five patients attended for assessment and the resultant positive oncology detection rate for these patients was 7%. In both audits, the patients diagnosed as having positive oncology results all had referrals that were compliant with the Department of Health guidelines. CONCLUSIONS: Both of these audits indicated that the national guide- lines for two-week referrals were usually appropriately followed in the two departments that were audited. However, in the future, further education of referring practitioners should ensure that these guidelines are followed better, making the service provided more efficient for all concerned.

Quantitative Light-induced Fluorescence-Digital as an oral hygiene evaluation tool to assess plaque accumulation and enamel demineralization in orthodontics.

OBJECTIVE: To assess the use of Quantitative Light-induced Fluorescence-Digital as an oral hygiene evaluation tool during orthodontic treatment. MATERIALS AND METHODS: In this prospective, randomized clinical trial, 33 patients undergoing fixed orthodontic appliance treatment were randomly allocated to receive oral hygiene reinforcement at four consecutive appointments using either white light (WL) or Quantitative Light-induced Fluorescence-Digital (QLF) images, taken with a device, as visual aids. Oral hygiene was recorded assessing the QLF images for demineralization, by fluorescence loss (ΔF), and plaque coverage (ΔR30). A debriefing questionnaire ascertained patient perspectives. RESULTS: There were no significant differences in demineralization (P  =  .56) or plaque accumulation (P  =  .82) between the WL and QLF groups from T0 to T4. There was no significant reduction in demineralization, ΔF, in the WL, or the QLF group from T0-T4 (P > .05); however, there was a significant reduction in ΔR30 plaque scores (P < .05). All the participants found being shown the images helpful, with 100% of the QLF group reflecting that it would be useful to have oral hygiene reinforcement for the full duration of treatment compared with 81% of the WL group (OR 2.3; P < .05). CONCLUSIONS: Quantitative Light-induced Fluorescence-Digital can be used to detect and monitor demineralization and plaque during orthodontics. Oral hygiene reinforcement at consecutive appointments using WL or QLF images as visual aids is effective in reducing plaque coverage. In terms of clinical benefits, QLF and WL images are of similar effectiveness; however, patients preferred the QLF images.
