The effects of different levels of dietary sucrose on root caries subsequent to gingivectomy in conventional rats infected with Actinomyces viscosus M-100.

Three groups of weanling, Sprague-Dawley-derived rats were inoculated with Actinomyces viscosus M-100 and fed powdered diet containing either 67%, 5%, or 0% confectioner's sugar. Two further groups were fed diet containing 5% confectioner's sugar and inoculated with Streptococcus sobrinus 6715 or S. sobrinus 6715 plus A. viscosus M-100. The most coronal 1 mm of gingiva was removed from maxillary and mandibular right molar quadrants (gingivectomy), and the animals re-inoculated following gingivectomy. The animals were killed 64 days following gingivectomy, and the lingual surface of mandibular first molar roots was measured for exposed root-surface area and root caries. In the groups of rats infected with A. viscosus M-100, root caries area was significantly greater in the group fed diet containing 67% confectioner's sugar. Sucrose level did not significantly affect the amount of exposed lingual first molar root area regardless of whether the tooth had been subjected to a gingivectomy. In the groups of rats receiving diet containing 5% confectioner's sugar, there were no significant differences in root caries area or exposed root-surface area, regardless of the infection status of the animals. In the rat model presented here, a high level of dietary sucrose was a necessary condition for the initiation of root caries in the absence of other readily fermentable carbohydrates.

Sarcoidosis of the gingiva--a case report.

Involvement of oral tissues by sarcoidosis is uncommon. We present a case of sarcoidosis involving the gingivae of a 60-year-old woman. The patient presents with an 18-month history of localized areas of gingival redness and swelling. She also has a previous history of sarcoidosis.

Peripheral ameloblastoma: a case report.

Peripheral ameloblastoma is an uncommon pathological variant of the more usual intraosseous central ameloblastoma. It most typically presents as a localized soft tissue mass occurring in the tooth-bearing areas of the jaws and is often provisionally diagnosed as an epulis. In this paper, a 43-year-old male presented with a three-year history of a painful, slowly enlarging gingival swelling. There was no evidence of bony involvement on radiographs but it was revealed histologically to be a peripheral ameloblastoma. Treatment was by wide local excision, including a bony margin, and primary closure. Long-term follow-up is imperative owing to possible recurrence and malignant potential.
