Background:Inferior alveolar nerve block (IANB) is a technique of dental anesthesia, used to produce anesthesia of the mandibular teeth, gingivae of the mandible and lower lip. The conventional IANB is the most commonly used the nerve block technique for achieving local anesthesia for mandibular surgical procedures. In certain cases, however, this nerve block fails, even when performed by the most experienced clinician. Therefore, it would be advantageous to find an alternative simple technique.Aim and Objective:The objective of this study is to find an alternative inferior alveolar nerve block that has a higher success rate than other routine techniques. To this purpose, a simple painless inferior alveolar nerve block was designed to anesthetize the inferior alveolar nerve.Materials and Methods:This study was conducted in Oral surgery department of Vinayaka Mission's dental college Salem from May 2009 to May 2011. Five hundred patients between the age of 20 years and 65 years who required extraction of teeth in mandible were included in the study. Out of 500 patients 270 were males and 230 were females. The effectiveness of the IANB was evaluated by using a sharp dental explorer in the regions innervated by the inferior alveolar, lingual, and buccal nerves after 3, 5, and 7 min, respectively.Conclusion:This study concludes that inferior alveolar nerve block is an appropriate alternative nerve block to anesthetize inferior alveolar nerve due to its several advantages.
Background and Objectives:The objective of this study is to evaluate the intraoral high tuberocity maxillary nerve block technique in zygoma and arch fracture reduction and fixation.Study and Design:This study was carried out at Arvind Multi-Specialty Hospital, Namakkal, Tamil Nadu on seven male patients with zygomatic bone and arch fracture.Materials and Methods:Intraoral high tuberocity maxillary nerve block administered in seven patients for management of isolated zygomatic bone and arch fracture. Lidocaine 2% measuring 4 mL with 1:80000 adrenaline anesthetic solutions was used to anesthetize maxillary nerve through a 3.2 cm length and 24G, needle. The following parameters were evaluated namely onset of anesthesia, nerve block duration, outcome of treatment and Patient's comfort.Results:The blocks were effective and patients were comfortable without pain during initial stage of surgery, but in latter stages two patients had mild to moderate pain. Duration of block varied from 60 to 90 min while onset varied from 3 to 10 min. There were vascular punctures in three patients, however, without hematoma.Conclusions:The maxillary nerve block is a good alternative option in selective cases of zygomatic bone fracture reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
