Studies from Osaka University add new findings in the area of life sciences
2009 AUG 4 - (NewsRx.com) -- Fresh data on life sciences are presented in the report 'Increase of salivary flow rate along with improved occlusal force after the replacement of complete dentures.' According to recent research published in the journal Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics, "We hypothesized that improvement of occlusal force would cause an increase in salivary flow rate (SFR) even in elderly complete denture wearers. The purpose of this study was to examine the change of SFR after the replacement of complete dentures." "Subjects were 22 edentulous outpatients of the Osaka University Dental Clinic. Unstimulated whole saliva was collected for 5 minutes. Stimulated whole saliva was collected for 2 minutes. The maximal occlusal force was measured with pressure-sensitive sheets. All measurements were done before and after replacement of the dentures. The replacement of complete dentures improved maximal occlusal force and increased their stimulated and unstimulated SFR. Stimulated SFR was positively correlated with unstimulated SFR both before and after the replacement. Maximal occlusal force, stimulated SFR, and unstimulated SFR after the replacement were significantly correlated to the measurements before the replacement," wrote K. Matsuda and colleagues, Osaka University. The researchers concluded: "These results suggest that proper prosthetic treatment can increase not only maximal occlusal force but also salivary flow rate." Matsuda and colleagues published their study in Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics (Increase of salivary flow rate along with improved occlusal force after the replacement of complete dentures. Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics, 2009;108(2):211-5). For additional information, contact K.
