ABSTRACT
Among 500 C.T. scan of temporomandibular joint (T.M.J.), examined since 1982 by bilateral direct sagittal method (Department of Radiology, Pr. A. TREHEUX, C.H.U. Nancy-Brabois), the authors have retained 14 cases of patients with symptoms related to dysfunction of the T.M.J. cured by surgery (Department of Maxillo Facial Surgery, Pr. STRICKER, C.H.U. Nancy). These cases were chosen among hundred patients annually examined by C.T. scan, for various diseases (dysfunctions of the T.M.J., traumatisms, infections, inflammatory diseases...). These correlations between radiology and surgery about 26 T.M.J. (2 patients underwent surgery only on one side) were: an accuracy with surgical findings for 19 cases (76%); in 6 cases (23%), a meniscus anteriorly displaced, non detected by C.T. scan was found by surgery; 2 cases of meniscus perforations (one in the frontal plane, the other sagittal) were surgical findings; in 1 case, a displacement was under-valued by C.T. scan; in 3 cases, arthrosic changes (1 case of REITER syndroma) were characterized by C.T. scan. The authors emphasize the value and the limits of evaluation of the internal derangements of the T.M.J. with direct sagittal C.T.

The fluoride retention in enamel was determined in vivo comparing the short-term unsupervised use of amine fluoride- and monofluorophosphate-sodium fluoride-dentifrices. Acid-etch enamel biopsies in the double-blind study showed that the fluoride content in enamel was significantly higher following use of the amine fluoride dentifrice, 959 ppm F vs 330 ppm F. Both dissolution of the enamel, determined by the amount of phosphorus (33.9 micrograms vs 50.9 micrograms) and the depth of etch (6.2 microns vs 9.6 microns) were significantly reduced after use of the amine fluoride compared to the monofluorophosphate-sodium fluoride combination.
