The aims of this study were to investigate the prevalence and location of oral exostoses and the concurrence of buccal and palatal exostoses with tori.
With clinical inspection and palpation, 960 Thais were examined for the presence or absence of torus palatinus (TP), torus mandibularis (TM), and exostoses.
Of the 960 subjects studied, 26.9% exhibited exostoses. Exostoses were more common in the maxilla than in the mandible (5.1:1). In addition, most of the exostoses were located on the buccal aspect of the jaws. The prevalence of exostoses increased with age (P = .000). Exostoses were significantly more common in men than in women (62.4% vs 37.6%, P =.000). Exostoses were concurrent with TM more frequently than with TP (36.2% vs 20.6%). The highest concurrence of exostoses with tori was observed in subjects who had both TP and TM (42.6%).
The occurrence of exostoses is related to increasing age. TM and exostoses may share the same causative factors, and functional influences may contribute. Our findings lend support to the hypothesis that the etiology of exostoses involves an interplay of multifactorial genetic and environmental factors.
本研究旨在调查口腔外生骨疣的患病率及部位，以及颊侧和腭侧外生骨疣与隆突的并发情况。
通过临床检查和触诊，对960名泰国人进行了腭隆突（TP）、下颌隆突（TM）和外生骨疣的检查。
在960名研究对象中，26.9%有外生骨疣。外生骨疣在上颌比下颌更常见（5.1:1）。此外，大多数外生骨疣位于颌骨的颊侧。外生骨疣的患病率随年龄增长而增加（P = .000）。男性外生骨疣明显比女性更常见（62.4%对37.6%，P =.000）。外生骨疣与TM并发比与TP更频繁（36.2%对20.6%）。在同时患有TP和TM的受试者中，外生骨疣与隆突的并发率最高（42.6%）。
外生骨疣的发生与年龄增长有关。TM和外生骨疣可能有相同的致病因素，功能影响也可能起作用。我们的研究结果支持外生骨疣的病因涉及多因素遗传和环境因素相互作用的假说。
