Human normal, periodontitis and overgrown gingival fibroblasts were assayed concerning proinflammatory cytokines secreting ability. Stimulating effect of gingival overgrowth-inducing drugs such as phenytoin, nifedipine or cyclosporine A and LPS on the secretion ability of each fibroblast specimen was also estimated. The supernatant of cultured medium was assayed cytokines by ELISA techniques. I...

Orthodontic therapy is known to be associated with the development of gingival recession. Several factors may be involved in the causal chain of this outcome, including anatomical and behavioral aspects. Among the anatomical aspects, the dimensions of the mandibular symphysis could play a predisposing role. This study evaluated the relationship between the mandibular symphysis dimensions prior ...

Discrepancy in the labial gingival margin of the maxillary incisors poses a major aesthetic problem. Orthodontic extrusion can improve the aesthetic problem caused by gingival margin levels before restoration. In these case reports, orthodontic extrusion was performed with palatal circumferential supracrestal fiberotomy for improving the discrepancy of the labial gingival margin. Two years post...

Gingival enlargement or gingival overgrowth is the abnormal growth of periodontal tissues. Drug induced gingival enlargement is one of the most common cause of enlarged gingiva. Drugs associated with gingival enlargement are divided in to three major groups namely anticonvulsants, immunosuppressant and calcium channel blockers [1]. Among the anticonvulsants, phenytoin is most commonly associate...

Having, during the past six years, had many opportunities of seeing cases in which symptoms of laryngeal trouble were present, and in which, on laryngoscopic examination, outgrowths in that part of the respiratory tract were found, I think that, without pretending to say anything new, I may still say a few words that are not altogether devoid of value. Deferring for the moment the consideration...

We consider a new family of factorial languages whose subword complexity grows as Θ(nα), where α is the only positive root of some transcendent equation. The asymptotic growth of the complexity function is studied with the use of analytical methods and in particular with a corollary of the Wiener-Pitt theorem. The factorial languages considered are also languages of arithmetic factors of infini...

Gingival fenestrations are an opening through unattached oral keratinized tissue. Gingival fenestrations have rarely been reported in the literature. However, these lesions may be more common than has been reported; lack of symptoms may inhibit patient awareness. The etiology of these lesions are clearly unknown. In this article, two cases of gingival fenestration due to poor oral hygiene in ad...

Gingival recession is the exposure of root surfaces due to apical migration of the gingival tissue margins. The principal objectives of treating a gingival recession are to achieve better esthetics and reduce hypersensitivity. The gingival biotype is an important modifying factor in the treatment of gingival recession. The purpose of this paper is to highlight the significance of changing the s...
