Mandibular Nerve Block - By Dr Saikat Saha Dr Saikat Saha
Mandibular nerve block techniques in short for Dental Surgeons. Mandibular nerve blocks are very important for all dental surgeons as it becomes a part and parcel of all dental and oral surgeons. This presentation will be useful for students of dentistry and doctors.
Local Anesthesia in childs , dentistry for adoleclsencehanimortezaeee
injection is the dental procedure that produces the greatest negative response in children.
Topical anesthetics are available in gel, liquid, ointment, and pressurized spray forms. However, the pleasant-tasting and quick-acting liquid, gel, or ointment preparations seem to be preferred by most dentists.
Ethyl aminobenzoate (benzocaine) liquid, ointment, or gel preparations are probably best suited for topical anesthesia in dentistry.
The mucosa at the site of the intended needle insertion is dried with gauze, and a small amount of the topical anesthetic agent is applied to the tissue with a cotton swab. Topical anesthesia usually produces an effect within 30 seconds, although keeping it in place between 2 and 3 minutes may provide the best results
The jet injection instrument is based on the principle that small quantities of liquids forced through very small openings under high pressure can penetrate the mucous membrane or skin without causing excessive tissue trauma.
Jet injection produces surface anesthesia instantly and is used instead of topical anesthetics by some dentists.
The method is quick and essentially painless; however the abruptness of the injection may produce momentary anxiety in the patient. This technique is also useful for obtaining gingival anesthesia before a rubber dam clamp is placed for isolation procedures
INFERIOR ALVEOLAR NERVE BLOCK (CONVENTIONAL MANDIBULAR BLOCK)
the mandibular foramen is situated at a level lower than the occlusal plane of the primary teeth of the pediatric patient. Therefore the injection must be made slightly lower and more posteriorly than for an adult patient.
An accepted technique is one in which the thumb is laid on the occlusal surface of the molar, with the tip of the thumb resting on the internal oblique ridge and the ball of the thumb resting in the retromolar fossa.
The barrel of the syringe should be directed on a plane between the two primary molars on the opposite side of the arch.
The depth of insertion averages about 15 mm but varies with the size of the mandible
Approximately 1 mL of the solution should be deposited around the inferior alveolar ne
Lingual nerve block
One can block the lingual nerve by bringing the syringe to the opposite side with the injection of a small quantity of the solution as the needle is withdrawn. If small amounts of anesthetic are injected during insertion and withdrawal of the needle for the inferior alveolar nerve block, the lingual nerve will invariably be anesthetized as well.
Long buccal nerve block
A small quantity of the solution may be deposited in the mucobuccal fold at a point distal and buccal to the last tooth
All facial mandibular gingival tissue on the side that has been injected will be anesthetized for operative procedures, with the possible exception of the tissue facial to the central and lateral incisors, which may receive innervation from ove

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

2. Inferior alveolar nerve block (IANB) is also known as the mandibular nerve
block.
Second most frequently used injection (after infiltration) in dentisty.
It has the highest percentage of clinical failures.
Useful technique in quadrant dentistry.
Administration of bilateral IANBs is rarely indicated in dental treatments as :
It produces discomfort, primarily from the lingual soft tissue anesthesia.
Patient feels unable to swallow.
Due to absence of all the sensations the patient is more like to self injure the
soft tissues.
A supplemental buccal nerve block is needed only when soft tissue anesthesia
in the buccal posterior region is necessary.
4. 1. Mandibular teeth to the midline.
2. Body of the mandible, inferior portion of the ramus
3. Buccal mucoperiosteum, mucus membrane anterior to mental
foramen (mental nerve).
4. Anterior two thirds of the tongue and the floor of the oral
cavity (lingual nerve).
5.Lingual soft tissues and periosteum (lingual nerve).
1. Procedures on multiple mandibular teeth in one quadrant
2. When buccal soft tissue anesthesia ( anterior to mental foramen) is necessary.
3. When lingual soft tissue anesthesia is necessary.
1. Infection or acute inflammation in the area of injection.
2. Patients who are more likely to bite their lip or tongue,like children or physically and mentally handicapped adult or child.
5. 1. A 25 gauge long needle is preferred.
2. Area of insertion : Mucous membrane on the medial side of
the ramus of the mandible, at the intersection of two lines-
• One horizontal representing the height of needle insertion
• The other vertical ,representing the antero-posterior plane
of injection.
3. Target area : inferior alveolar nerve as it passes downwards
to the mandibular foramen but before it enters into the
foramen.
4. Landmarks:
• Coronoid notch (greatest concavity on the anterior border
of the ramus)
• Pterygomandibular raphe (vertical portion )
• Occlusal plane of the mandibular posterior teeth
6. 1. Assume the correct position
• For a right IANB , 8 o’clock position facing the patient
• For a left IANB, 10 o’clock position facing in the same direction as the patient
2. Position the patient in a supine or a semisupine position. Open the
mouth wide to allow greater visibility and access
3. Three parameters must be considered during the administrations of
IANB:
• Height of injection
• Anteroposterior placement of the needle
• Depth of penetration
7. 1. Place the index finger or the thumb of your left hand in
the coronoid notch
2. An imaginary line extends posteriorly from the fingertip in
the coronoid notch to the deepest portion on the
Pterygomandibular raphe.
3. This imaginary line should be parallel to the occlusal plane
of the mandibular molar teeth and lies 6-10 mm above
the occlusal plane in most patients
1. It is three fourths of the anteroposterior
distance from the coronoid notch back to the
deepest part of the Pterygomandibular raphe
8. Prepare tissue at the injection site and place the
barrel of syringe in the corner of the mouth on
the contralateral side , usually corresponding the
premolars.
1. Slowly advance the needle until you
can feel a bony resistance
2. The average depth of penetration to
bony contact will be 20-25 mm,
approx. 2/3 or ¾ the length of the
long dental needle
3. Needle tip should be located slightly
superior to the mandibular foramen
9. 4. When the bone is contacted , withdraw approx. 1mm to prevent subperiosteal
injection.
5. Aspirate in two planes. If negative , slowly deposit 1.5ml of anesthetic over a
minimum of 60 seconds
6. Slowly withdraw the syringe , and when half of its length remains within the
tissues, reaspirate. If negative , deposit 0.2ml of the remaining solution to
anesthetize the lingual nerve
• In most patients this is not necessary as the LA from the IANB anesthetizes the lingual nerve
7. Withdraw the needle and make the needle safe.
10.
11. • Tingling or numbness of lower lip (anesthesia of mental nerve)
• Tingling or numbness of tongue (anesthesia of lingual nerve)
• Using an electrical pulp tester
• No pain is felt during dental therapy
The needle contacts the bone, preventing over insertion and complications
• Donot deposit local anesthesia if bone is not contacted
• Avoid pain by not contacting the bone too forcefully
12. One injection provides wide area of anesthesia (useful for quadrant dentistry
• Wide area of anesthesia not indicated for localised procedures
• Rate of inadequate anesthesia is 31%- 81%
• Intraoral landmarks not consistently reliable
• Chances of positive aspiration are 10% - 15%
• Lingual and lower lip anesthesia may sometimes lead to self inflicted soft tisse trauma
• Partial anesthesia where bifid inferior alveolar nerve and mandibular canals present
13. The most common causes of absent or incomplete IANB are :
1. Deposition of anesthetic too low , below the mandibular foramen
2. Deposition of anesthetic too far anteriorly (laterally) on the ramus
3. Accessory innervation to the mandibular teeth
• Several nerves provide the mandibular teeth with accessory innervation but
mylohyoid nerve acts as the prime candidate
• The Gow-Gates mandibular nerve block which blocks the mylohyoid nerve is not
associated with problems of accessory iinervation
4. Incomplete anesthesia of central and lateral incisor
• This is due to overlapping fibres of the contralateral inferior alveolar nerve
14. 1. HEMATOMA
• Swelling of tissues on the medial side of the
mandibular ramus after deposition of anesthetic
2. TRISMUS
• Muscle soreness or limited movement
• A slight degree of soreness when openening the
mandible is common
• More severe soreness is rare
3. TRANSIENT FACIAL NERVE PALSY
• Produced by deposition of local anesthesia into
the body of the parotid gland, blocking the VII
cranial nerve.
• Signs and symptoms include inability to close
the lower eyelid and drooping of upper lip on
the effected side
