RESUMO
OBJECTIVE: To evaluate the novel assessment of gingival contour volume measurement from digital impressions compared with traditional clinical indices (Modified Gingival Index and Bleeding Index) and oral microflora following a dental prophylaxis. METHODS: Following baseline examinations and full mouth digital impression using the LAVA™ Oral Chairside Scanner (COS), subjects had one maxillary quadrant and the contra-lateral mandibular quadrant randomly allocated to receive a complete dental prophylaxis. Subjects then brushed twice daily at home using a standard toothpaste. After 1, 2, 4, 6 and 12 weeks gingivitis examinations and digital impressions of the maxillary and mandibular arches were taken. RESULTS: Significant improvements in gingivitis for the prophylaxis versus no prophylaxis quadrants were observed up to six weeks using both the traditional gingivitis indices and the assessment of change in gingival contour volume from the digital impressions. CONCLUSION: The assessment of changes in gingival contour volume may be a promising technique for the objective and quantitative clinical evaluation of products or procedures used to treat gingivitis. The effects of a dental prophylaxis were demonstrated by both this novel measure and traditional clinical indices.

The time to resumption of driving after insertion of an implantable cardioverter-defibrillator (ICD) was evaluated in the Dual Chamber And VVI Implantable Defibrillator trial. Most patients were advised not to drive for 3 to 6 months after the ICD was implanted. Patients were surveyed at 3-, 6-, or 9-month intervals to characterize their driving habits, with 101 of 137 (73.7%), 98 of 146 (67.1%), and 79 of 135 (58.5%) responding. Of respondents, 82% recalled being told not to drive for a specified time after ICD implantation. These patients generally obeyed recommendations (association between recommended time and time of resumption, p <0.001) from medical personnel.

Previous studies have shown a poor correlation between health and quality-of-life assessments by patients, physicians, and nurses. Some have argued that patients are treated impersonally in clinical trials. Because one would expect that patient care would be compromised if this were the case, we used the Dual-chamber And VVI Implantable Defibrillator (DAVID) clinical trial setting to see if these assertions truly reflect the assessments of quality of life by health care professionals. Physicians, nurses, and patients in the DAVID trial had concordant assessments of the patients' perception of health status. The findings dispel assertions that patient concerns are not reliably assessed.
