The use of digital texture image analysis in determining the masticatory efficiency outcome

Abstract

The mixture level of gum samples consisting of two colours can be assessed visually, using the electronic colorimetric method, employing digital image processing techniques and specially designed software. The study investigates the possibility of an alternative method called “digital texture image analysis” (DTIA) to assess improvement of masticatory efficiency in denture wearers. The objectives were i) to evaluate whether DTIA discriminates changes in the colour mixing ability within a group over time; ii) to determine whether DTIA can be used to detect improvement in chewing ability; iii) to select the most appropriate DTIA feature that sufficiently describes masticatory efficiency in CDs wearers. The study was designed as an intra-individual evaluation of masticatory efficiency, which was assessed in participants with new dentures in three follow-up times. A set of four texture features was used in the current study. Uniformity, Contrast, Homogeneity and Entropy of the obtained chewing-gum samples were correlated to the degree of gum comminution. A statistically significant difference in masticatory efficiency was observed based on the values of the analysed DTIA variables of gum samples—Uniformity, Contrast, Homogeneity, and Entropy—have changed in the participants during the observation period. The improvement of the masticatory function in relation to the mixing ability of two-coloured chewing gum could be traced by monitoring changes in the values of DTIA variables. The most increasement of masticatory efficiency was observed by monitoring DTIA parameters such as contrast, and homogeneity.

Subjective and Objective Assessment of Chewing Performance in Older Adults with Different Dental Occlusion

“…Chewing ability can be assessed either subjectively, as a self-reported individual perception and satisfaction with mastication (using questionnaires and interviews), or objectively, based on different clinical chewing tests where changes of natural food or artificially produced test specimens are evaluated [ 6 ]. Simpler, faster, and more hygienic method for the analysis of changes among chewed test food particle size is the computer-assisted image processing [ 7 , 8 , 9 ]. Subjective patient-reported outcome measures (PROMs), which are extremely important in evidence-based dentistry, include validated questionnaires or interviews for evaluation of a self-perceived masticatory function from the patient's perspective, some of them taking into account only the domain of chewing, while others include social and psychological factors [ 10 , 11 ].…”

Chewing efficiency and contact area discrepancies in Angle's class I and II malocclusion: A comparative study

“…Using the Hubba-Bubba Tape chewing gum and by the ViewGum Software, Halazonetis et al ( Halazonetis, Schimmel et al, 2013 ) and Chawisa et al ( Chawisa Thangjittiporn, 2021 ) reported respectively 0.144 ± 0.082 and 0.051 ± 0.024. Lemić et al ( Milić Lemić, Rajković et al, 2021 ) reported, also, near values (0.063 ± 0.025) with Five Tape sugarless chewing gum.…”

“…The variance of hue serves as a measure for the level of color mixture, indicating better color mixing and improved chewing efficiency when the hue variance is lower. ( Milic, Rajkovic et al, 2021 ).…”

Is the Number of Appointments for Complete Denture Fabrication Reduced with CAD-CAM? A Literature Review

“…This first sweep was conducted automatically by the application of search filters and identification of exclusion terms in the advanced search interface of PubMed. After an initial screening from both scholars, 24 additional articles were excluded, including seven reviews or surveys [12,19,[34][35][36][37][38], seven describing workflows that required preexisting dentures [39][40][41][42][43][44][45], one not referring to digital workflows in clinical practice [46], four analyzing material properties [47][48][49][50] and five laboratory studies [51][52][53][54][55]. Next, 10 articles were eligible for full text analysis, of which one was excluded because of insufficient classification between CDs and overdentures [56], and one because it was a technique presentation accompanied with clinical pictures without any presentation of the cases [57]).…”
