In 1973 Gow Gates reported new technique for mandibular anesthesia using extraoral Landmarks & deposition of the anesthetic solution on the condylar neck area.
According to his reports the success rate of anesthesia was higher than that of the conventional inferior alveolar nerve block technique.
Thls study was carried out to determine the effectiveness of local mandibular anesthesia, using the conventional inferior alveolar nerve block technique and newly devised the Gow Gates technique.
Author reviewed 124 patients, over the L4 year olds, were divided into 2 groups, 28 patients administered the conventional inferior alveolar nerve block, as control group and 96, experimental group was utilized the Gow Gates technique.
The following results were obtained;
1. Success rate of anesthesia In the conventional technique was 89.3%, while in the Gow Gates technique showed 92.7%.
2. Rate of positive blood aspiration In the conventional technique was 10.7%, the Gow Gates technique was 6.25%.
3. The onset of anesthesia In the Gow Gates technique was slower than In the conventional technique.
4. By using extraoral Landmarks, the anesthetic manipulation was much easter in the Gow Gates technique.
