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 …

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 …

Objective To examine the reliability of bite force for evaluating orthodontic tooth movement-
induced pain in rats. Design Orthodontic tooth movement-induced pain was induced by …

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 …

We present simple method to assess dental pain in the awake rat. Using a sensitive strain
gauge we examined changes in bite strength and bite pattern in rats following dental injury …

Aims: To test the hypotheses that masseteric inflammation produces a reduction of mean
bite force and success rates and that classical anti-inflammatory agents prevent …

Introduction Pain-related behavior secondary to masticatory function can be assessed with
the rodent bite force model. A reduction of the bite force has been shown to be related to …

The aim of the experiment was to test the hypothesis that experimental pain in the masseter
muscle or temporomandibular joint (TMJ) would perturb the oral fine motor control, reflected …

Objective: To test the efficacy of an animal model of pain and stress and evaluate the effects
of celecoxib administered when orthodontic force is applied. Materials and Methods: A 20-g …
