INTRODUCTION Vascular spongy intraosseous (intraosseous itself-IOA, intraligamentary-ILA, intraseptal-ISA) anesthesia, located in the supplemental section, take the larger place in dental practice [1]. Lalabonova et al. (2005) showed that in Bulgaria for 76% of dentists ILA has become a routine [2]. A survey of 800 from 2500 American endodontists found that about 95% of them use supplemental methods of anesthesia, mostly ILA-50%, and also intraosseous two-stage injection [3]. The popularity of

... pongy anesthesia contributed to the simplicity of it implementation, more than 2 times smaller dose and high efficiency in the absence of severe paresthesias of soft tissues [4-6]. Prevalence contributed to a new injection technique: pressure (multiplication) [1] and computer syringes (C-CLAD Systems) [7] , as well as a special needle [8]. Separation methods of local anesthesia on diffuse and vascular that we proposed [1,9] , is related to the safety of dental spongy anesthesia. Separation methods of local anesthesia and diffuse disease, proposed by us [1,9] , it is related to the safety of dental anesthesia spongy. Additional injections were in a section of classic diffuse with zero frequency of positive aspirations [10]. In addition to our research 61% of positive aspirations in the dental intraosseous anesthesia observed by other authors [11]. PURPOSE : To evaluate the systemic complications of dental spongy vascular injection based on publications and our records. ABSTRACT Separation of the methods of local anesthesia on diffuse and vascular that we proposed (Petrikas et al.), is related to the safety of dental spongy anesthesia. PURPOSE: To evaluate the systemic complications of dental spongy vascular injection based on publications and our records. Spongy anesthesia containing epinephrine, in each subject causes systemic reactions of the sympathetic or parasympathetic type, usually the first. There are significant changes in heart rate and systolic blood pressure. They do develop in the first minute, falling to fourth. They are not typical to classical anesthesia. Headache and tachycardia are specific symptoms of severe systemic reactions to spongy injection. Chest pain is another terrible symptom. After classic (293) and spongy (431) anesthesia it was analyzed 17/56 systemic complications, properly. Quantitatively, the complication to vascular (spongy) injection was more common. It is essential that the vegetative (sympathetic and parasympathetic) reactions were observed only after a spongy injection. All reactions-complications were mild, transient and reversible. However, the transformation of reactions in severe complications are possible, as was the case in the 70s.
