Objective: To determine whether orthodontically treated patients with cleft lip and palate (CLP) possess a different masticatory function than those of untreated patients with normal occlusion. Design: Occlusal contact area, occlusal force, as well as masseter and anterior temporal muscular activity were measured during maximum voluntary clenching (MVC) tests. Mandibular left and right lateral movements during mastication were also assessed. To further elucidate the nature of masticatory function, especially to determine the rate of abnormal jaw movement patterns, a parametric error index (EI) was set. Finally, masticatory efficiency was evaluated with a glucose sensitive measuring device. Participants: Fifteen patients with CLP who had previously completed the orthodontic treatments required to achieve an acceptable and more harmonious occlusion accepted to volunteer in this study along with 21 untreated patients who already possessed a normal occlusion. Results: Patients with CLP showed a significantly lower occlusal force, reduced occlusal contact area, and decreased masticatory efficiency as well as significantly higher EI value when compared with controls. However, there was no significant difference when analyzing muscle activity, although masticatory efficiency was significantly different between the 2 groups. Despite this result, the scores obtained by the patients with CLP in the masticatory efficiency tests were still in the normal range. Conclusions: Orthodontic treatment for adult patients with CLP provides a satisfactory result for the patients’ masticatory ability albeit significantly less ideal compared with untreated patients with normal occlusion.

BACKGROUND The proposed experimental design was done to determine if a relationship exists between the occlusal load applied and the size of the markings produced from tooth contact when dental articulating paper and T-Scan are interposed alternatively. OBJECTIVE Objective of this study was to compare the relationship between contact markings on an articulating paper and T Scan for an applied occlusal load. METHODS In this in vitro study, dentulous maxillary and mandibular dies were mounted on a metal jig,articulating paper, and T-Scan sensor were placed alternatively between the casts. Loads simulating occlusal loads began at 25N and incrementally continued upto 450N.The resultant markings (180 marks resulting from articulating paper and 138 marks of T-Scan) were photographed and the marks were analyzed using MOTIC image analysis and sketching. Descriptive statistical analysis was carried out with one-way analysis of variance (ANOVA), student t-test and Karl Pearson’s correlation coefficient method. RESULTS The size of an articulating paper mark may not be a reliable predictor of the actual load content within the occlusal contact. T-Scan gave more predictable results of actual load content within the occlusal contact. CONCLUSIONS Statistically interpretation of the data indicated that with articulating paper, the mark area increased non-linearly with increasing load and there was a false positive result. The characteristics of the paper mark appearance did not describe the amount of occlusal force present on a given tooth. The contact marking obtained using T Scan for an applied occlusal load indicated that the mark area increased with the increase in the load and gave more predictable results of actual load content within the occlusal contact.
