[Role of intraligamentous blocks in dentistry]

In more than 2,000 documented cases intraligamentous blocks were found to be an attractive and uncomplicated alternative to dental anesthesias available to date. Given adequate practice and used with discrimination, this patient-friendly method produces a fairly good local effect which is sufficient for all of the usual dental treatments requiring no more than 20 to 40 minutes. Most of them can be done without any appreciable wait and with no more than 0.2 to 0.5 ml of the anesthetic solution so that intraligamentous blocks are an excellent solution for problem patients, e.g. those with cardiac and circulatory instability, etc.
