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.

Sorrow Of The Dentist by Ayam Chhatkuli

And now, something slightly different than what you would expect from Meddy Bear. We are here to prove that doctors also have an artistic side to them.

We present to you a poem written by one of our fans, Ayam Chhatkuli from Nepal.

Enjoy!

 

 

 

 

Sorrow of the dentist

Before I joined the med school

the focus of my sight was different

I used to see a whole human

All I see now is the teeth with calculus and stain.

 

When I see an old man walking

all I remember is a complete denture

I’m fed up with my prostho work

help me God I surrender

 

The man has a class I fracture

46 got a root stump

A life with no joy and rupture

Is equal to a dump

 

I come to encounter mainly 2 sorts of patients

Few are philosophical

And many are hysterical

 

People actually are very unhygienic

They bath with Quatar soap and have a Jean Patou’s spray

But use a single brush for 6 months

and walk with a grossly decayed tooth till the next may

 

Inside the heat of this mask

My beard failed to grow

Nose felt difficult to breath

Salivation decreased its flow

 

These days I dream of teeth

Good dreams angels appear as a canine

Bad dreams impacted lateral at age nine

She insists to describe her beauty

All I can see is her anterior cross-bite

with peg laterals

Falling in love for a dentist

is almost like winning the battles.

3 Ways Dentists can Optimize Postoperative Care

Our love for sweet desserts and late night hunger binges is an attribute of the first world lifestyle. Prolonged poor oral hygiene and unhealthy snacking habits often take a toll on our teeth. Did you know that carbonated cold beverages contain acids that literally erode our teeth? Sugary drinks cause tooth decay and accumulation of cavities in your mouth. Your teeth are basically exposed bones that protrude outside of your body.
Gulping down soft drinks that contain phosphoric acid, citric acid and tartaric acid erode away our teeth over time, starting from the outer most layer of teeth, the enamel. Fortunately, we have dentists, the unsung heroes of our time. They can save us from losing our teeth when you’d have thought there is no hope left.
Surgical dental intervention is the ultimate safety net for our consumer driven society. A dentist can help you save your teeth but only you can prevent oral diseases from occurring. Even after oral surgeries, success is partially dependent on the post operative care on the patient’s part. Here are some tips for dentists to execute post operative patient care just the right way.

Give reasons
Patients especially the young ones don’t like being told they’re supposed to brush twice a day, floss regularly, or to stay away from sweets, which makes it very important to voice out all the ‘whys’ behind the instructions. When a smoker is told exactly why they shouldn’t smoke post oral surgery for a prescribed length of time, it might not fully convey the importance of the instruction, unless you make it clear that smoking causes loss of the clot needed for healing. The more you prolong the healing process, the more pain they’d have to endure. This will help patients connect the dots and follow instructions better.

Post operative care instructions might actually reduce pain
It has been found that providing patients with an adequate understanding of postoperative preparatory information can help the patient set their expectations realistically, and consequently reduce their overall pain experience. Tell the patients the degree of pain they might experience, how long it would last, and how they can counter it. These instructions reinforce the patient’s belief that the pain is normal and helps the patient prepare for it. Nice way to alleviate pain, we’d say.

A hardcopy printout won’t suffice
Giving away written instructions equips the patient with the entire dos and don’ts of postoperative care that they can refer to from time to time. A written set of instructions lead to greater compliance on the patient’s part because, sometimes, verbal instruction just isn’t enough. Factors such as language barriers, age and anxiety can influence the patient’s ability to retain the information you have provided them verbally. However, the list of good post operative practices that you hand out to the patients might accidentally end up in the washing machine with the clothes or might get misplaced too. It’s always a good practice to go beyond the print out and email the postoperative care instructions to the patients. This way, they won’t lose it. In fact, 64% of Americans are attached to their smartphones. As a result, fewer interruptions and lesser patient dissatisfaction would occur.
