Biologic preparation of diseased root surfaces. An in vitro study. 1987

D A Assad, and R M Dunlap, and S R Weinberg, and D R Ahl

The study evaluated the effect of 2% sodium desoxycholate combined with whole plasma from a single donor on gingival fibroblast attachment to diseased root surfaces. Twenty extracted periodontally involved teeth were cut into halves buccolingually and sterilized by moist heat under high pressure. The diseased root surface of each control half was rubbed with a sterile cotton pellet saturated with Dulbecco's phosphate-buffered saline (PBS). The diseased root surface of each experimental half was rubbed with a sterile cotton pellet saturated with 2% sodium desoxycholate and then rubbed with a pellet soaked in human plasma. The control and experimental halves were placed in separate petri dishes, and a fibroblast cell suspension was added to each dish. The mean number of attached cells per half tooth was calculated for each group. Tooth surfaces treated with PBS (controls) showed a mean of 307 +/- 63 attached cells for 17 tooth halves; the experimental treated surfaces exhibited a mean of 650 +/- 130 attached cells for 16 halves. The difference between these numbers was statistically significant (P less than 0.01). These findings suggest that the desoxycholate/plasma combination enhanced in vitro fibroblast attachment to diseased root surfaces.

D003840	Deoxycholic Acid	A bile acid formed by bacterial action from cholate. It is usually conjugated with glycine or taurine. Deoxycholic acid acts as a detergent to solubilize fats for intestinal absorption, is reabsorbed itself, and is used as a choleretic and detergent.

D014092	Tooth Root	The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.
