The amazing anatomy of Dental Plexus

As you probably are already aware of, the trigeminal nerve is quite a vast one. It itself has three major branches which innervate a vast region of the head, including such internal parts as the sinuses and dura mater, and, of course, big part of the upper digestion earns credit to the trigeminal nerve – including the muscles involved in chewing and swallowing as well as the sense of your gums and teeth.

All of this is done via smaller branches which furthermore innervate their target structures. The dental plexus is one of those branches, which actually consist of two quite different parts (see the image below, precisely demonstrated by Anatomy Next).

Although they do innervate teeth, the superior branch comes from the maxillary nerve and the inferior branch originates from the mandibular nerve. The superior dental plexus arises from the infraorbital nerve in the infraorbital canal. This branch of nerves furthermore innervates superior molar, premolar, canine and incisor teeth together with gingiva surrounding them before the infraorbital nerve exits the canal via the infraorbital foramen and innervates the skin of the upper lip, cheek, nasal ala, lower eyelid and conjunctiva.

It is always worth remembering the close location of the maxillary sinus. Not only the nerves can be a common thing between the teeth and the maxillary sinus, but part of the dental infections can spread in the sinus as well.

The inferior dental plexus, however, arises from the mandibular branch of the trigeminal nerve as it travels through the mandibular canal on its way to become the mental nerve before giving a branch to the incisive teeth. It is worth noting though, that the gingiva is innerved via the inferior dental plexus just as it is with the upper dental plexus. The incisive branch, as the name suggests, innervates the incisors, and the inferior dental branches innervate the premolars and molars together with the canines.

Although the anatomy of teeth innervation might seem challenging to learn and remember, for me it is a piece of art. Such complex structures are amazing to explore and we really do hope that the illustrations and renders will make it easier for students out there as well.

3 Amazing Remedies to Alleviate Headaches

Headaches are a very common occurrence nowadays. They have become increasingly prevalent due to its established positive association with the many factors present in today’s urban lifestyle such as city’s photochemical smog, high cholesterol diets, and ubiquitously-present radio waves due to cell phones.

The instant need for gratification is understandable because headaches can be a real bummer! However, popping a pill every time you experience a headache might not be the best approach for a number of reasons. Pharmacological agents act as ligands for certain receptors in our body, to activate them and bring about the required effects. The repetitive use of drugs can induce a resistance in receptors against the drug, which means that after prolonged use, the same quantity of the drug won’t do the job anymore. Time to increase your dose! Additionally, there are also a bunch of uninvited side effects that come along with the therapeutic effect. You could avoid all of these effects by following these simple, effective and established botanical headache remedies.

1.     Cayenne

Cayenne is widely known to be a natural anti-inflammatory agent. The active compound in Cayenne that is responsible for the anti-inflammatory effect is called Capsaicin. Capsaicin disrupts the cascade of reactions that is required to produce pain. Hence by hindering one of the steps in the series of reactions, Capsaicin can eliminate pain. Here’s how you can make this magical potion to alleviate the pain:

Dissolve ¼ teaspoon of cayenne powder in 4 ounces of warm water. Use a cotton swab to stir it around, and apply the moist swab gently on the inside of your nostril. It will sting a little but that’s just a sign that it’s working! In no time, your headache will hopefully be no more.

2.     Almonds

How many of you have dads who are regular almond eaters? Almonds contain an enzyme called Salicin that is isolated and sold as an over-the-counter medication for pain relief. However, you can avoid the unwelcomed side effects of these medications by eating the nut whole. Natural foods always contain natural mediators that don’t let the effect of one compound exceed another to a harmful limit. The problem arises when we isolate the chemical and take it in its pure form. So, try eating a bunch of almonds the next time you come across an irritating headache.

3.     Feverfew

Through trial and research feverfew plant has proven to be a great natural therapeutic agent for headaches and even migraines! Migraines can be extremely painful. Feverfew contains a chemical substance Parthenolide which is an active ingredient against headaches. Headaches occur due to the vasoconstriction of our blood vessels that can cause nearby nerves to be pressed. This is the reason we experience pain, but because Parthenolide causes vasodilation, it can relax those tensed blood vessels once again. Thereby, restoring the healthy impulse transmission of your nerves and alleviate your headache. It’s like taking an aspirin minus the side effects! This is how you can use feverfew to prepare a relieving concoction for yourself:

Take an ounce of feverfew flowers (either fresh or dried) and add them to a pint of boiling water. Stir and let it boil for 10 minutes. This will slowly extract essential nutrients of feverfew flowers such as Parthenolide. Strain it, and drink half a cup twice a day.
