The Solution ?

The Solution ?

Teach skills of:

1. Asking focused clinical questions,

2. Finding the strongest evidence,

3. Critical appraisal of the evidence and

4. Judgment regarding application of the evidence.

The aim is to promote lifelong learning skills.

Mini CAT Exercises: Examples

1) Format a focused (PICO) question: Example #1

Clinical Question The KaVo website states: “DIAGNOdent aids in the detections of caries. Even very small lesions are detected at the earliest stage, enabling you to protect and preserve the tooth substance.”

Assignment: Formulate a PICO question to help you find the best evidence about the accuracy of DIAGNOdent in detecting early dental caries. P: In adult dental patients… I: …how effective is DIAGNOdent… C: …compared to the gold standard histology… O: …in the detection of proximal dental caries limited to enamel?


UTHSCSA

Pick 2 articles or advertisements and write 2 PICO questions

Email the PICO Questions to Mabel Hernandez by Wed., Jan 11, 5:00 pm

2) Given a PICO question, select appropriate MeSH search terms:

Clinical Question The KaVo website states: “DIAGNOdent aids in the detections of caries. Even very small lesions are detected at the earliest stage, enabling you to protect and preserve the tooth substance.” PICO Question In dental patients how effective is DIAGNOdent compared to the gold standard histology in the detection of proximal dental caries limited to enamel?

What is the evidence that teaching Evidence Based Practice changes anything AND how should we teach it?

A systematic review 23 Studies Results:

Stand alone teaching of EBM improved knowledge but not

skills, attitudes, or behaviour.

Clinically integrated teaching improved knowledge, skills,

attitudes, and behaviour.

Conclusion: Teaching of evidence based medicine must be

moved from classrooms to clinical practice.

CAT OF THE MONTH

Clinical Quest ion: In a patient with a pronounced frenulum labii superioris, or lingual frenulum, does laser frenectomy provide a faster healing time and/or less pain when compared to conventional surgical frenectomy? Clinical Bot tom Line: Laser frenectomy results in significantly less postoperative pain and impairment of function compared to conventional surgical frenectomy. Best Evidence: Haytac MC, Ozcelik O. Evaluation of patient perceptions after frenectomy operations: a comparison of carbon dioxide laser and scalpel techniques. J Periodontol. 2006 Nov;77(11):1815-9. PMID: 17076605 Kara C: Evaluation of patient perceptions of frenectomy: A comparison of Nd:YAG laser and conventional techniques. Photomed Laser Surg. 2008 26(2):147-152, PMID: 18341414 Key Results: Postoperative pain scores in both studies were significantly lower at 1 and 7 days in patients treated with laser surgery. Eighty-five percent and 92.5% of patients in the conventional surgery group used analgesics during the first postoperative week compared to 33% and 5% of the laser surgery group in the two studies. Patient assessments of discomfort during eating and speaking were also lower in the laser groups. Comments on Evidence: Both studies were Randomized Clinical Trials completed in two different Turkish university clinics using two different laser instruments, the Smarty A10; DEKA, (Firenze Italy) and the Luxar Nova Pulse LX-20SP, (Bothell WA). Forty patients completed both studies and groups were treated the same, except for the intervention. The investigators aimed to create equivalent sizes of surgical wound in both groups. Subjects were asked to measure and report postoperative pain, postoperative discomfort in eating, and postoperative discomfort in speaking on visual analog scales at days 1 and 7. Applicabilit y or Significance: Subjects were females and males, all non-medicated and healthy, with good oral hygiene, ranging from 18-26 years of age. All had labial or lingual frena extending to the interdental papilla of the central incisors.
