BackgroundEffective pain control in Dentistry may be achieved by local anesthetic
techniques. The success of the anesthetic technique in mandibular structures
depends on the proximity of the needle tip to the mandibular foramen at the moment
of anesthetic injection into the pterygomandibular region. Two techniques are
available to reach the inferior alveolar nerve where it enters the mandibular
canal, namely indirect and direct; these techniques differ in the number of
movements required. Data demonstrate that the indirect technique is considered
ineffective in 15% of cases and the direct technique in 1329% of cases.ObjectiveObjective: The aim of this study was to describe an alternative technique for
inferior alveolar nerve block using several anatomical points for reference,
simplifying the procedure and enabling greater success and a more rapid learning
curve.Materials and MethodsA total of 193 mandibles (146 with permanent dentition and 47 with primary
dentition) from dry skulls were used to establish a relationship between the teeth
and the mandibular foramen. By using two wires, the first passing through the
mesiobuccal groove and middle point of the mesial slope of the distolingual cusp
of the primary second molar or permanent first molar (right side), and the second
following the oclusal plane (left side), a line can be achieved whose projection
coincides with the left mandibular foramen.ResultsThe obtained data showed correlation in 82.88% of cases using the permanent first
molar, and in 93.62% of cases using the primary second molar.ConclusionThis method is potentially effective for inferior alveolar nerve block, especially
in Pediatric Dentistry.
