The previous studies have shown alterations in the periodontium of both humans and animals. Our objective was the evaluation of collagens I, IV and V of the periodontium of Wistar rats exposed to noise rich in low frequency components. Materials and Methods: 5 groups (each with 10 animals) were exposed to continuous low frequency noise (LFN). The LFN, from previously recorded white noise, frequency filtered and amplified, was applied in growing periods of 1, 3, 5, 9 and 13 weeks, in order to characterize the alterations with exposure time. A control group of ten animals was kept in silence. These animals were used in groups of 2 as aged‑matched controls. After exposure, sections were obtained including teeth, alveolar bone and periodontium and observed after immunollabeling for collagens I, IV and V. Results: A significant increase in collagen I was observed in exposed groups (P < 0.001) (Kruskal‑Wallis test). Post‑hoc comparisons (Mann‑Whitney test with Bonferroni correction) showed an increase in collagen I in animals exposed for 3 weeks or more (P < 0.001). The same test was applied to collagen V where significant differences were found when comparing control and exposed groups (P ≤ 0.004). The t‑test for independent samples was applied to collagen type IV where no significant differences were found (P = 0.410), when comparing to the control group. Discussion: As in other organs, we can observe fibrosis and the newly formed collagen is likely to be “nonfunctional,” which could have clinical impact. Conclusion: Noise may constitute a new comorbidity for periodontal disease."Wolters KluwerRepositório ComumMendes, José JoãoOliveira, Pedro Miguel AntunesBrito, JoséÁguas, Artur Manuel Perez NevesMartins dos Santos, José António Mesquita2015-03-31T08:48:54Z2014-07-01T00:00:00Z2014-07-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.26/8170engBaltazar Mendes JJ, Oliveira PA, Brito J, Neves Águas AP, Martins dos Santos JM.
