Describe the path the trigeminal nerve takes and the type of neurons it contains.
The three branches of the trigeminal nerve (V1,V2,V3) converge in the trigeminal ganglion converge in Meckel’s cave. The trigeminal ganglion is ananlogous to the dorsal root ganglion of spinal cord. From the trigeminal ganglion a single thick root enters the brainstem at the level of the pons.
Motor fibers pass through the ganglion but their cell bodies are located within the pons (motor nucleus of the 5th nerve).
Opthalmic Branch (V1) (sensory only: genral somatic afferent) → superior orbital fissure Maxillary Branch (V2) (sensory only: genral somatic afferent) → foramen rotundum Mandibular Branch (V3) (sensory and motor: GSA and special visceral efferent) → foramen ovale
Motor neurons of V3 innervate
4 muscles of mastication (temporalis, masseter, medial and lateral pterygoid)
4 other muscles (tensor veli palatini, mylohyoid, anterior belly of the digastric, tensor tympani)
What can you do to NaOCl to make it more effective?
• Increase temperature • Perform continuous replenishment • Increase concentration • Use agitation • Increase time of contact • Use fresh solution So: Volume, T, time, concentration, agitation (PUI, sonic), fresh vs. old prepared solution
Does buffering hypochlorite make a difference in effectiveness? authors?
No. Buffering hypochlorite with bicarbonate renders the solution unstable with a decrease in shelf life to less than 1 week (Zehnder et al 2002). The antimicrobial efficacy of a fresh bicarbonate-buffered solution is only slightly higher or not elevated at all compared to that of a nonbuffered counterpart (Zehnder et al 2002)
