Summary
This study investigated the effectiveness of injecting Prilocaine-fenylpressin below the mylohyoid muscle for dental anesthesia. Partial anesthesia of the mylohyoid nerve was achieved in 21% of participants, suggesting a sensory role in mandibular molars.
Area of Science:
- Dentistry
- Anesthesiology
- Neuroscience
Background:
- The mylohyoid nerve's role in dental anesthesia is not fully understood.
- Effective anesthesia of the mylohyoid nerve is crucial for certain dental procedures.
Purpose of the Study:
- To evaluate the efficacy of a specific injection technique for mylohyoid nerve anesthesia.
- To determine the success rate of achieving anesthesia via this method.
Main Methods:
- 1.8 ml of 3% Prilocaine-fenylpressin was injected beneath the mylohyoid muscle in voluntary dental students.
- Injection site was immediately behind the distal root of the first molar.
- Anesthesia of the mylohyoid nerve was the target outcome.
Main Results:
- Partial anesthesia of the mylohyoid nerve was achieved in 21% of the subjects.
- This suggests the mylohyoid nerve may possess sensory functions for the first mandibular molar.
Conclusions:
- The investigated injection technique shows limited success for complete mylohyoid nerve anesthesia.
- Further research is needed to confirm the sensory innervation of the first mandibular molar by the mylohyoid nerve.
