“…Inferior alveolar nerve block is the technique most frequently used for local anesthesia when performing restorative and surgical procedures in the mandible 8 ; however, the approximate failure rate of these procedures ranges from 5 to 15% 31 or 15 to 20% according to Kaufman 14 (1984), reaching even higher percentages in pulpal anesthesia 6,32 .…”

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.

“…11,12 For experienced operators high success rates have been achieved 14 but for inexperienced operators high failure rates have been reported. 15 This is likely to be due to difficulties with appropriate visualisation and alignment of the extraoral reference planes and the intraoral puncture points, which have been described as 'impossible' by some authors. 16,17 Zandi et al describe a device that facilitates the Gow-Gates technique to unfamiliar practitioners to achieve higher success rates.…”

Background:Since introduced by Gow-Gates GA in 1973, Gow-Gates mandibular nerve block (GMNB) has played an important role in the area of dental local anesthesia. However, compared to the conventional inferior alveolar nerve block (IANB), this technique seems to fail to attract the attentions of general practitioners in South Korea. The aim of this study was to prove the clinical real value, mainly the anesthetic efficacy, of GMNB in minor oral surgery.Methods: The study group comprised 40 patients (15 males and 25 females) who were randomly allocated to receive GMNB or IANB for extraction of third molars. Both techniques utilized two 1.8 ml dental cartridges of 2% lidocaine including 1：100,000 epinephrine for each patient. Pulpal and gingival tissue anesthesia of mandibular premolars and molars were recorded at 0, 15 and 40 minutes after administration of local anesthetics using both an electric pulp tester and a sharp dental explorer.Results: The success rates of pulpal and gingival tissue anesthesia in the IANB group were not significantly different from the GMNB group in overall efficacy. Patient's and operator's satisfaction ratings were also not significantly different between two groups. Interestingly, the injection pain of GMNB group was significantly lower than that of IANB group.Conclusion: This study demonstrated that the anesthetic efficacy of pulpal and gingival tissue of GMNB was not inferior to that of IANB. The GMNB could be a good alternative of the IANB in most of minor oral surgical procedures. (JKDSA 2011; 11: 16～21)

Design and development of a device for facilitation of Gow-Gates mandibular block and evaluation of its efficacy

Abstract: We concluded that our device facilitates the Gow-Gates technique and increases its success rate irrespective of the gender of the patient, the side of the mandible being injected, and the experience of the administrator who uses the instrument.
