Local anaesthesia makes the patient and the dentist comfortable to do treatment with least amount of discomfort, but dental patient’s most frequent fear is of receiving local anaesthetic injections. The present study attempted to evaluate and compare patient’s perception to pain, pressure and discomfort induced by three types of injections (Infiltration, mental nerve block and inferior alveolar nerve block injection) for mandibular anaesthesia. Patients were asked to grade pain, pressure and discomfort associated with injection insertion on visual analog scale. Inferior alveolar nerve block was graded the most painful nerve block, while Infiltration was graded as the least painful. Patient’s perception to pressure and discomfort was highest for inferior alveolar nerve block and lowest to mental nerve block.
The present study compares the effectiveness of inferior alveolar nerve block and infiltration in the extraction of posterior mandibular teeth. 90 patients were divided into two groups. Group 1 included 45 patients and for each tooth, two injections (0.6 ml out of 1.8 ml of 2% lidocaine from one dental cartridge with 1:80000 adrenaline) were administered, one Local Anesthetic injection was given parallel to the long axis of the tooth in the depth of buccal sulcus with short needle and dental syringe. The second injection was delivered to the lingual vestibule of the mouth's floor to anaesthetize the soft and hard lingual tissue with short needle and dental syringe, whereas Group 2 included 45 patients and were given Inferior Alveolar Nerve Block (1.5 ml of 2% Lidocaine) and Long Buccal nerve Infiltration (0.3ml of 2% Lidocaine). In our study, we found 78% patients was pain free and 22% was feeling pain during tooth extraction in patients who were given infiltration, whereas patients in which Inferior alveolar nerve block was given, 89% patients was pain free and 11% were feeling pain during tooth extraction. 94% of males and 85% of females experienced no pain, whereas 6% of males and 15% of females felt pain during the extraction. The present study suggests that Infiltration can be used as an alternative approach to inferior alveolar nerve block during the extraction of Mandibular posterior teeth.
Aim of the present study is see the position of mental foramen on OPG in the local Punjabi population. This study was carried out on 305 digital panoramic radiographs of North Indian (Punjabi) population. Patients aged from 18 to 64 years were divided into 2 groups. Group A consisted of those patients between 18 and 40 years and Group B were between 41 and 64 years of age. On the right side, the most common shape of the metal foramina in Males and Females are (51.4%) and (39.2%) respectively. The most common horizontal location of MF on the right side was found to be accounting to be 54.3% and 45.5% in males and females respectively. The vertical location is variable on the right and left side and the location is In males, size was bit larger on left than right side and in females; it was almost same on both the sides.
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.
