BACKGROUND: The Oral Behaviors checklist (OBC) is a valid 21-item instrument quantifying the self-reported frequency of oral behaviors. An Italian version (OBC-It) has been released recently. Anxiety and oral behaviors are known to be associated in individuals with orofacial pain due to temporomandibular disorders (TMD). However, information about this relationship in pain-free individuals is still limited. OBJECTIVES: The aim of this study was to test the reliability of the OBC-It and its reduced version (OBC-It 6), focusing on tooth clenching related wake time oral behaviors, and the effect of patient instructions on reliability...

The aim of this study was to test the reliability of a method to measure the masticatory performance of complete denture wearers employing a colour-mixing ability test and assessment by visual and electronic colourimetric analysis. A sample of 75 subjects was selected from patients who received new conventional complete dentures. Masticatory tests were performed using a two-colour chewing gum that was masticated for 5, 10, 20, 30 and 50 chewing cycles, performed in a random order. The mixing level of the two colours of the chewed gum was assessed visually by two independent raters based on a 5-point ordinal scale...

No consensus has been reached regarding the best occlusal scheme for making complete dentures. Thus, the purpose of this systematic review was to compare bilateral balanced occlusion (BBO) with other occlusal schemes (canine guidance, lingualized occlusion, and zero degree) in complete dentures. The schemes were compared in terms of quality of life/satisfaction and masticatory performance. Two independent reviewers performed a comprehensive search of studies published in or before October 2017 using the PubMed/MEDLINE, Scopus, and Cochrane Library databases...

Tooth loss, decreased mass and strength of the masticatory muscles leading to difficulty in chewing have been suggested as important determinants of eating and nutrition in the elderly. To compensate for the loss of teeth, in particular, a majority of the elderly rely on dental prosthesis for chewing. Chewing function is indeed an important aspect of oral health, and therefore, oral rehabilitation procedures should aim to restore or maintain adequate function. However, even if the possibilities to anatomically restore lost teeth and occlusion have never been better; conventional rehabilitation procedures may still fail to optimally restore oral functions...

There is little evidence about sensation in individuals with diabetes mellitus (DM) in the dental research field. We investigated whether pain thresholds (PTs) differ between individuals with and without DM (non-DM; NDM). To this end, we assessed whether PTs obtained from the oral cavity, hands, and feet differed from each other and across groups, and whether PTs differed for the three current frequencies used for testing (2000 Hz, 250 Hz, and 5 Hz). PT measurements were obtained from the oral mucosa and the tips of the fingers and toes of 56 volunteers, including 21 individuals with DM (12 men and 9 women, average age: 72...
