The group of nerves primarily responsible for sensation in the upper molar region is the branches of the maxillary nerve. The maxillary nerve is one of the three major branches of the trigeminal nerve (cranial nerve V) and innervates areas of the face, particularly the upper jaw. It supplies sensory innervation to the maxillary teeth, including the upper molars, as well as to the surrounding tissues such as the gums, cheeks, and nasal cavity.

Branches of the maxillary nerve, specifically the posterior superior alveolar nerve, provide the sensation in the upper molar region by supplying the molar teeth as well as the surrounding bone and soft tissue. Understanding this nerve's role is crucial in dentistry, particularly during procedures such as extractions or anesthesia, where accurate targeting of the nerve is necessary for effective pain management.

On the other hand, the mandibular nerve primarily serves the lower jaw, and its branches do not provide sensory information for the upper molars. The abducens nerve is responsible for innervating the lateral rectus muscle of the eye, which has no involvement in dental sensation. Lastly, the facial nerve is primarily responsible for motor functions in facial expressions and provides some sensory innervation but does not play a
