However, the biomechanics of tongue squeezing is still unclear. The aim of present study is to investigate the effect of the initial mechanical properties of gels on the change in tongue pressure production during squeezing and swallowing. As test sample, nine kinds of gels with three fracture force and three fracture strain were prepared. Tongue pressure during squeezing and swallowing gels was measured by using an ultra\u2010thin tongue pressure sensor with five measuring points attached on the hard palate in seven healthy participants, and analyzed at four phases; Initial squeeze, Middle squeeze, Last squeeze, and Swallowing. The maximal magnitude of tongue pressure was increased for gels with higher fracture force at most measuring points and was decreased for gels with higher fracture strain at some measuring points on the median line during Initial and Middle squeezing. However, no influence by fracture force and strain was found in magnitude during Last squeezing and Swallowing. The duration of tongue pressure increased for gels with higher force at most measuring points during Middle squeezing, although no influence by strain was found during each phase. The results clearly show how the initial fracture properties of gels influence on tongue pressure production during each phase of food oral processing, which clarified one aspect of squeezing with tongue, as the compensatory mastication.<\/jats:p>","DOI":"10.1111\/jtxs.12593","type":"journal-article","created":{"date-parts":[[2021,2,23]],"date-time":"2021-02-23T06:42:21Z","timestamp":1614062541000},"page":"303-313","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of fracture properties of gels on tongue pressure during different phases of squeezing and swallowing"],"prefix":"10.1111","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8823-4159","authenticated-orcid":false,"given":"Kazuhiro","family":"Murakami","sequence":"first","affiliation":[{"name":"Division of Comprehensive Prosthodontics Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"},{"name":"Department of Prosthodontics Gerodontology and Oral Rehabilitation, Graduate School of Dentistry, Osaka University  Suita Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshitsugu","family":"Tokuda","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics Gerodontology and Oral Rehabilitation, Graduate School of Dentistry, Osaka University  Suita Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8074-9016","authenticated-orcid":false,"given":"Kazuhiro","family":"Hori","sequence":"additional","affiliation":[{"name":"Division of Comprehensive Prosthodontics Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"},{"name":"Department of Prosthodontics Gerodontology and Oral Rehabilitation, Graduate School of Dentistry, Osaka University  Suita Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshitomo","family":"Minagi","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics Gerodontology and Oral Rehabilitation, Graduate School of Dentistry, Osaka University  Suita Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumiko","family":"Uehara","sequence":"additional","affiliation":[{"name":"Division of Comprehensive Prosthodontics Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3212-9365","authenticated-orcid":false,"given":"Jumpei","family":"Okawa","sequence":"additional","affiliation":[{"name":"Division of Comprehensive Prosthodontics Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sayaka","family":"Ishihara","sequence":"additional","affiliation":[{"name":"San\u2010Ei Gen F.F.I., Inc.
