2025
This video demonstrates the induction of orofacial neuropathic pain in a rat model by ligating the infraorbital nerve. This results in nerve damage and inflammation, causing abnormal pain signaling and mimicking chronic pain conditions, which can be used to study the orofacial pain assay.

We present a user-friendly, high-throughput operant system for the evaluation of pain behaviors in awake, conscious rodents. The Orofacial Pain Assessment Device (OPAD) can assess pain through a reward/conflict paradigm thus providing a more humane way of testing. This protocol will yield more clinically relevant and translational data from rodents.

A lengthening in meal duration represents orofacial nociceptive behavior in rodents similar to the guarding behavior of humans with orofacial pain. Eating is a behavior that requires no training or animal manipulation, requires cortical participation, and is not competing with other experimentally induced behaviors, distinguishing this assay from alternative reflex or operant measurements.
FAQs
These functions depend on coordinated activity among jaw muscles, teeth, mucosal tissues, glands, and sensory and motor nerves. The same integrated organization allows structures to contribute to related tasks while responding to changing functional demands. Examining these interactions helps biologists connect physical structures with the control of jaw movement, swallowing, sensation, and speech.
Growth and tissue remodeling change the relationships among craniofacial bones, muscles, teeth, and other tissues across development. These changes can influence how the system performs feeding, breathing, speech, and facial expression. For biology, following this developmental organization provides a basis for understanding normal craniofacial formation as well as congenital anomalies.
Sensory nerves provide information from orofacial tissues, while motor nerves help coordinate the muscles involved in movement and expression. Their interaction with bones, muscles, mucosal tissues, and glands supports activities such as jaw movement, swallowing, sensation, and facial expression. Studying these neural relationships is therefore relevant to research on facial pain and functional changes.
Research can examine how craniofacial structures develop, how jaw movement and swallowing are coordinated, and how tissue relationships support oral health. Investigators can also compare normal development with congenital anomalies or disease-related changes. This broad scope makes the orofacial complex useful for linking anatomy, development, tissue biology, and function within a single integrated system.
Dental and periodontal research can place affected teeth and supporting oral tissues within their wider biological setting. Because the system includes teeth, mucosal tissues, glands, blood vessels, muscles, and nerves, disease-related changes may be considered alongside surrounding structures and functions. This perspective supports investigation of oral health and the effects of tissue disruption on orofacial performance.
Understanding the relationships among its bones, muscles, teeth, mucosal tissues, glands, blood vessels, and nerves can guide research on replacing or repairing damaged tissues. The goal is not only to restore individual structures but also to consider how they contribute to coordinated function. This context is relevant to tissue regeneration and clinical approaches for restoring orofacial function.
