Thus, the difference in the mode of nutritional intake is expected to affect the oral environment, but this has not yet been fully clarified. The purpose of this study was to investigate, in tube-fed patients, changes in the oral moisture and the counts of microorganisms in saliva and tongue coating, which occur after oral ingestion resumption. Methods: Study participants were 7 tube-fed inpatients of the Niigata University Medical and Dental Hospital (72.7±8.5 years old) who received dysphagia rehabilitation at the Unit of Dysphagia Rehabilitation until oral ingestion resumption. Their oral health, swallowing, and nutrition status, oral mucosal moisture, amount of unstimulated saliva and the counts of microorganisms (total microorganisms, streptococci, Candida) in saliva and tongue coating were investigated and compared before and after the recommencement of oral intake. Results: Tongue coating, choking, oral mucosal moisture and amount of unstimulated saliva were improved significantly after resumption of oral ingestion. The other investigated parameters did not significantly change, except for the streptococci in tongue coating, which significantly increased 1 week after oral ingestion recommencement, but decreased thereafter. Conclusion: After oral intake resumption, oral mucosal moisture and amount of unstimulated saliva were improved. However, because of a transitory increase in the counts of streptococci with oral ingestion recommencement, it is important to appropriately manage oral hygiene in these patients, according to the changes in their intraoral microbiota. 3 25 2016 79 88 TODENTJ-10-79 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2015-4-8 2016-1-28 2016-2-11 2016-3-25 https://creativecommons.org/licenses/by/4.0/legalcode 10.2174/1874210601610010079 1553506425 https://opendentistryjournal.com/VOLUME/10/PAGE/79/ https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-79/TODENTJ-10-79.xml Dysphagia Langmore S.E. 13 69 1998 10.1007/PL00009559 Langmore SE, Terpenning MS, Schork A, et al.
