Traditional culture-based techniques for assessing infection of the root canal system are difficult to use and prone to error. Real-time assessment of the microbial status of the root canal system using laser fluorescence would help address these limitations.. This study evaluated the performance of thin optical fibers of different diameters, with either plain or conically modified ends, connected to a KaVo KEY 3 laser with an inbuilt 655-nm laser fluorescence diagnostic system. Penetration was tested on sectioned extracted teeth. Fluorescence recordings were made ex vivo in the canals of extracted teeth with known periapical pathology. Several endodontic medicaments and irrigants were also tested for autofluorescence.. The fibers could reach the apical third of the root canal, unless the canals had distal curvatures greater than 15 degrees . Penetration was greater for conical than for plain fibers. Fluorescence readings were significantly higher in infected canals (range, 19-99) than in noninfected canals and sound radicular dentin (range, 2-8). Of the medicaments examined, only tetracycline-based medicaments gave false-positive fluorescence signals.. Fluorescence analysis of root canals with optical fiber probes has the potential for real-time assessment of the microbial status of the root canal system in clinical practice.

The TAE C14 has been evaluated as a diagnostic method of small bowel contamination in a group of patients operated for gastric disturbances. It has been compared with bacterial culture and bile salts chromatogrpahy of jejunum liquid and therapeutic response. 36 patients have been studied and divided in 3 groups: a) negative control: 8 subjects without pathology; b) positive control: 6 patients with intestinal resection and 1 with intestinal scleroderma, all of them with steatorrhea; c) gastric operated patients: 16 BII with and without vagotomy, 3 gastroenteroanastomosis and vagotomy, 1 superselective vagotomy and pyloroplasty and 1 B I, all the patients had steatorrhea, except one with BII. The period elapsed between the operation and the studies varied from 1 to 17 years (X: 4.9 +/- 4.1). The average value of steatorrhea was 23.9 +/- 10.2 g/24 hs. 100% of group b and 80% of group c had abnormal TAE C14. In 80% of the patients of the group c chromatogrpahy was performed and it agreed with TAE C14 in 80% of the studies. Bacteriology was positive in 100% of 18 studies, coinciding with TAE C14 in 70% patients. Therapeutic control of 100% of group c was positive in 90%.
