BACKGROUND: A number of studies have evaluated the Stabident (Fairfax Dental, Miami) intraosseous anesthesia technique. A second intraosseous technique--the X-tip system (X-tip Technologies, Lakewood, N.J.)--has been introduced, but no scientific studies have yet compared its effectiveness to that of the Stabident system. The authors undertook a study to compare the two systems' anesthetic outcomes in primary intraosseous injections in mandibular posterior teeth. METHODS: The authors, using a crossover design, randomly administered a primary Stabident intraosseous injection and a primary X-tip intraosseous injection, at two separate appointments, to 41 subjects. Subjects were asked if they perceived an increase in heart rate with the intraosseous injections. The research team blind-tested each subject's first molar, second molar and second premolar with a pulp tester at two-minute cycles for 60 minutes after the injection. Anesthesia was considered successful when two consecutive pulp tester readings of 80 were obtained. RESULTS:Anesthetic success rates for the Stabident technique and the X-tip technique, respectively, were 93 percent and 93 percent for the first molar; 95 percent and 95 percent for the second molar; and 81 percent and 83 percent for the second premolar, with no significant differences (P > .05) between the two techniques. For both intraosseous techniques, onset of pulpal anesthesia occurred within the first two minutes, but the duration of anesthesia declined steadily over the 60 minutes. Eighty-five percent of the subjects had a perceived increase in heart rate with the Stabident injection and 93 percent with the X-tip injection, with no significant differences (P > .05) between the techniques. CONCLUSIONS AND CLINICAL IMPLICATIONS: The two primary intraosseous injection techniques were similar regarding anesthetic success, onset, duration and perceived heart rate increases.
