“…Qualitative indicators (articulating paper and articulating silk) can measure only the location and number of tooth contacts while quantitative indicators (electro-optic and resistive techniques such as T-scan) can measure the time and force characteristics of tooth/teeth contact [17]- [19].…”

Occlusal force has the main role in determining the teeth health in general and determining the chewing, muscle and TMJ function. The objective of this study was to find if there was any relation between the preferred chewing side and the force, measured by T-scan III system. The total number of 90 (46 female and 44 male) dental students was included in this study. They were asked whether their preferred chewing side was right, left or both. Afterwards, the occlusal forces in habitual occlusion, using T-Scan III Electronic device (IP-CO position mode, MA-mode, MA sensitivity setting) were measured. The data were presented as Mean ± SD. Spearman correlation was used to find the correlation between the occlusal force and chewing side. Differences in P < 0.05 were considered significant. There were 90 subjects (46 female and 44 male) mean age 23.3 (SD ± 2.2 years) included in the study. The preferred chewing side of 42 subjects was the right side, 24 of them preferred the left side and the other 24 preferred both sides as the chewing side. Occlusal force was higher in the preferred chewing side (P < 0.05) but using Spearman correlation, there was no statistical significance of occlusal force between the groups, the left side (r = −0.143, P > 0.05) and the right side (r = 0.143, P > 0.05) according to the preferred chewing side. In this study, the relation between the preferred chewing side and occlusal force was found.

“…Excessive load on the masticatory system due to occlusal instability eventually gives rise to temporomandibular damage. The influence of occlusion on the onset of TMD is debated, and still a source of controversy [10][11][12][13][14]. A detailed, exhaustive study of these factors will help in furthering the knowledge of the possible existence of the association.…”

Introduction: This systematic literature review was performed to establish the mechanism, methodology, characteristics, clinical application and opportunities of the T-Scan III System as a diagnostic tool for digital occlusal analysis in different fields of dentistry, precisely in orthodontics. Methods: Searching of electronic databases, using MEDLINE and PubMed, hand searching of relevant key journals, and screening of reference lists of included studies with no language restriction was performed. Publications providing statistically examined data were included for systematic review. Results: Twenty potentially relevant Randomized Controlled Trials (RCTs) were identified. Only ten met the inclusion criteria. The literature demonstrates that using digital occlusal analysis with T-Scan III System in orthodontics has significant advantage with regard to the capability of measuring occlusal parameters in static positions and during dynamic of the mandible. Conclusion: Within the scope of this systematic review, there is evidence to support that T-Scan system is rapid and accurate in identifying the distribution of the tooth contacts and it shows great promise as a clinical diagnostic screening device for occlusion and for improving the occlusion after various dental treatments. Additional clinical studies are required to advance the indication filed of this system. Importance of using digital occlusal T-Scan analysis in orthodontics deserves further investigation.

“…The hardware comprised of a recording handle (which holds the recording sensor) that is connected to the computer through a USB port. Held securely within the recording handle is a ''sensor support'', which keeps the 100 lm thick recording sensor properly extended flat within the mouth, during all intraoral recording procedures (Koos et al, 2012).…”

a b s t r a c tIntroduction: Recently, some published studies show there is a multifactorial origin for Temporomandibular Disorders, but the dental occlusion's contribution to the development of Temporomandibular Disorders, and how it may influence the adaptive capacity of the Stomatognathic system, it's still unclear. The aim of this study is to evaluate the correlation between the Occlusion Time and Temporomandibular Disorders. Methods: A total of 54 patients were enrolled in the study (24 males and 30 females, mean age 27.94 ± 8.21 years). The TMD group (8 males and 10 females) consisted of subjects who presented with at least 1 of the following signs of Temporomandibular Disorders: Temporomandibular Joint sounds (clicking or crepitation), Temporomandibular Joint locking episodes, limited mandibular opening, painful limitation of mandibular movements, pain to palpation of the Temporomandibular Joint or of the masticatory muscles. The control group (16 males and 20 females) presented as free from Temporomandibular Disorders. The T-Scan III computerized occlusal analysis system was to record the subjects' Occlusion. Times during eight mandibular opening-closing movements. Results: The two-ways ANOVA test analyzed the variations for group and sex, showing that the TMD group mean Occlusion Time (0.64 ± 0.21 s) was statistically significantly longer than the control group mean Occlusion Time (0.45 ± 0.17 s) (p < 0.001). Significant differences were also found for gender where the mean OT of female subjects was longer than males one with statistical significance (p-value < 0.01). Conclusions: The computerized analysis of the Occlusion Time in patients affected by TMJ problems has to be carefully considered as adjunctive instrumental device.
