Objective: To investigate by behavioral methods the relationship between emotional stress
and pain during experimental tooth movement in rats. Materials and Methods: Sixteen male …

Aim: To test whether orofacial mechanical and thermal hypersensitivities occur in rats during
orthodontic tooth movement (OTM). Methods: Sprague-Dawley rats (140 to 160 g) were …

Aims: To evaluate the transient effects of orthodontic treatment on the mechanical detection
threshold (MDT) and mechanical pain threshold (MPT) of the buccal attached gingiva and …

The mechanism of orthodontic pain and discomfort is poorly understood partly because of
the limited number of animal behavioral models for pain assessment. This study aimed to …

(ie orthodontic pain) and changes in dental occlusion. Clinical realms and research …

This study was carried out to evaluate pain in rats by monitoring their facial expressions
following experimental tooth movement. Male Sprague‐Dawley rats were divided into the …

Aims: To investigate how trait anxiety and stress jointly affect the sensory and jaw motor
responses to a tonic orofacial nociceptive stimulus. Methods: Orthodontic separators were …
