ABSTRACT
Objective To compare the anesthetic effect of atocaine adrenaline injection and lidocaine injec -tion in wisdom tooth extraction .Methods 220 patients with wisdom teeth were selected as the research subjects . According to the random table method ,the patients were randomly divided into research group 110 cases ( a total of wisdom teeth 132,maxillary wisdom teeth 47,mandibular wisdom tooth 85) and the control group 110 cases(a total of wisdom teeth 129,maxillary wisdom teeth 51,mandibular wisdom tooth 78).The research group received atocaine adrenaline injection ,the control group received lidocaine hydrochloride injection .The effects of anesthesia ,VAS score and adverse reactions in the two groups were observed .Results The total effective rate of maxillary wisdom tooth anesthesia in the research group(100.00％) was significantly higher than that in the control group (90.20％),and the difference between the two groups was statistically significant (χ2 =6.358,P<0.05).The total effective rate of mandibular wisdom tooth anesthesia in the research group (100.00％) was significantly higher than that in the control group(92.31％),and the difference between the two groups was statistically significant (χ2 =6.788,P<0.05).The VAS score of maxillary wisdom tooth anesthesia in the research group [(2.57 ±0.65)points]was significantly lower than that in the control group [(2.87 ±0.63) points],and the difference between the two groups was statistically significant(t=2.319,P<0.05).In the control group,there was 1 case of hematoma caused by blood vessels ,and no complications occurred in the research group .Conclusion The anesthetic effects of articaine adrenaline injection in wisdom tooth extraction is better than lidocaine hydrochloride injection , without any complications , it is worthy of clinical promotion .
