What supply the gingival buccal tissue of premolars, canines and incisors:
a- Long buccal.
b- Inferior alveolar nerve.***
c- Superior alveolar nerve.
Mental nerve(branch of inferior alveolar) supply buccal gingivae of the mandibular anterior teeth and the premolars.
----------------------------
The inferior alveolar nerve is a branch of the mandibular nerve, which is the third branch (V3) of the fifth cranial pair, the trigeminal nerve).
Innervates the incisors, canines, premolars and lower molars.
It is subdivided into branches: mental nerve, incisor, buccal, temporal and lingual auricles.
The mental nerve innervates the skin of the chin, lower lip and buccal gum of the lower teeth.
The incisor nerve innervates teeth and gums of the lower anterior teeth.
The buccal nerve innervates the skin of the premolar and molar cheeks and gums.
The temporal auricular nerve innervates the parotid gland, tympanum, internal acoustic meatus, ear flag, and posterior part of the atm.
The lingual nerve innervates the tongue mucosa of all lower teeth, submandibular and sublingual glands, and mucosa of the buccal floor.
It is also responsible for the innervation of the vestibular periodontium of the premolar and anterior teeth.
In some cases the inferior alveolar nerve crosses the midline, innervating structures on the opposite side.

The cases of odontalgia are very frequent in the daily life of the dentist and, for this, he needs to have a mastery of the anesthetic technique, especially in the case of the lower teeth.
Lower alveolar nerve regional block is used to anesthetize all jaw teeth (hemi-arch), including oral tissues and tongue.
However, although there are several techniques, anesthesia of this nerve is complicated, causing failure for the vast majority of students who are starting the profession and making the daily work of professionals already difficult. Objective: To present a new methodology in which both the student and the dentist can perform training to achieve the success of lower alveolar nerve block anesthesia.
Methodology: In an acrylic jaw, we will place a bubble wrap, where only one bubble selected through an adhesive label will be placed on top of the mandibular foramen.
On top, we will put a modeling clay, hiding the entire branch of the jaw and part of the base. Direct Technique:
(1) place the index finger at the height of the trigonoretromolar;
(2) position the syringe in the contralateral region;
(3) With finger reference, insert the short needle releasing small amount of anesthetic.
After the procedure, remove the mass and check if the bubble wrap was perforated, ie the anesthetic was injected correctly.
Conclusion:
This model is a form of dynamic learning, where it is possible to train and increase the skills, dexterities and knowledge of the anatomical and functional aspects of this difficult art of anesthetizing the inferior alveolar nerve.
