Reliability of a new test food to assess masticatory function Khoury-Ribas, Laura Ayuso Montero, Raúl Rovira Lastra, Bernat Peraire Ardèvol, Maria Martínez Gomis, Jordi Odontologia Masticació Aliments Propietats mecàniques Dentistry Mastication Food Mechanical properties Objective: This study assessed the reliability and validity of masticatory function assessment using a new test food, Optozeta. Design: Thirty-five adults participated in the cross-sectional clinical part of the study; ten of them performed a retest. They performed two free-style masticatory tests consisting of five trials of 20 cycles each chewing three pieces of Optosil or Optozeta placed in a latex bag. Optozeta was created by mixing 50% Optosil with 50% of Zetalabor. Masticatory performance, masticatory laterality and chewing rate were assessed. Reliability and construct validity were assessed using the intraclass correlation coefficient (ICC) and Spearman correlations, respectively. Results: Higher ICC values were observed for each aspect of masticatory function as assessed using Optozeta compared with Optosil. All the participants showed a lower median particle size value using Optozeta than Optosil. For each masticatory parameter, a high correlation was observed between using Optosil or Optozeta. Conclusions: Optozeta seems to have good construct validity and appears to be more reliable than Optosil as a test food to assess masticatory function. 2018-06-05T12:24:46Z 2018-12-09T06:10:20Z 2018-03 2018-06-05T12:24:46Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 0003-9969 https://hdl.handle.net/2445/122794 674804 29241026 eng Versió postprint del document publicat a: https://doi.org/10.1016/j.archoralbio.2017.12.006 Archives of Oral Biology, 2018, vol. 87, p. 1-6 https://doi.org/10.1016/j.archoralbio.2017.12.006 cc-by-nc-nd (c) Elsevier Ltd, 2017 http://creativecommons.org/licenses/by-nc-nd/3.0/es info:eu-repo/semantics/openAccess 6 p. application/pdf application/pdf Elsevier Ltd Articles publicats en revistes (Odontoestomatologia)
