PURPOSE: To clarify whether trigeminal somatosensory function will be changed after orthodontic treatment as well as after orthognathic surgery. METHODS: A series of 20 @entity1 with a mean age of 20.9  1.74 years were recruited. Thermal quantitative sensory tests were conducted before orthodontic treatment (T0), before orthognathic surgery (T1), 2 months after orthognathic surgery (T2), and 6 months after orthognathic surgery (T3). The @entity5032 ( @entity5032 ), @entity158 threshold (CPT), warm detection threshold (WDT) and @entity158 ( @entity158 ) were determined. SPSS 16.0 software package was used for statistical analysis. RESULTS: There were significant differences with lower threshold (higher sensitivity) in V2L (P=0.006) and V2R (P=0.017) for WDT at T1 compared to T0. A significantly higher threshold (lower sensitivity) was detected for @entity5032 in V2L (P=0.028) at T1 compared to T0. A significantly higher threshold (lower sensitivity) was detected for @entity158 in V2R (P=0.028) and V3R (P=0.017) at T1 compared to T0. There were significant differences with higher threshold (lower sensitivity) V3L (P=0.024) for WDT at T3 compared to T0. A significantly lower threshold (higher sensitivity) was detected for CPT in V2R (P=0.036), @entity69338 (P=0.012) and V3R (P=0.044) at T3 compared to T0. There were significant differences with higher threshold (lower sensitivity) in V2L (P=0.009), V2R (P=0.034), @entity69338 (P=0.032) and V3R (P=0.001) for @entity158 at T3 compared to T0.Numbness was reported most frequently at T2 (93.33%), but this symptom tended to decrease with time (T3-20%). @entity16043 's exact test showed that there was no significant difference at T2(P=0.303) and T3(P=0.530) between participates who underwent genioplasty or not. CONCLUSIONS: The results indicated that thermal somatosensory function was altered after initial orthodontic treatment and orthognathic surgery. However, partial recovery of thermal sensory function can be expected in the majority of @entity1 .
