Morphometrical Study

Background: Mental foramen is situated in the anterolateral aspect of the body of the mandible. It lies below either the interval between the premolar teeth or the second premolar tooth, midway between the upper and lower borders of the body of the mandible. It transmits mental nerves, arteries, and veins. The mental nerve is a branch of the inferior alveolar nerve which supplies sensation to the lower lip, labial mucosa, lower canines, and premolars. The most useful injection for anaesthetizing the mandibular teeth is the inferior alveolar nerve block. To anaesthetize the anterior teeth including canines and premolars it is better to inject the anesthetic solution adjacent to the mental foramen instead of giving inferior alveolar nerve block. Aim: To Study the Morphological and Morphometrical Study of Mental Foramen in Dry Adult Human Mandible and Its Clinical Relevance in dental practice. Materials and methods: A total of 100 numbers of dry adult mandibles of unknown sex with complete dentition and intact alveolar sockets collected from the Department of Anatomy, Meenakshi Medical College Hospital and Research Centre, were used for this study. The shape, size, location, number of the mental foramen, direction of opening of mental foramen was measured on both sides of the mandible by using a vernier caliper. Results: The most frequent position of mental foramen was in line with the apex of the 2nd premolar (right side 86.1% and left side 84.75%). The second common position was between 1st and 2nd premolar (Right side 5.2% and Left side 5.85%). The shape of the mental foramen was oval in 63.3% and rounded in 36.7% respectively. The direction of opening of mental foramen in most of the mandible was posterosuperior. The mean distance from mental foramen to symphysis menti, lower border of the mandible, and posterior ramus of the mandible was 26.67mm, 11.76 mm, and 62.95mm respectively. The mean measurement of the angle of the mandible was 128°. Conclusion: Knowledge about the Morphometric measurement of mental foramen is important during various surgical dental procedures.

Background: It is important to control the pain associated with root canal treatment (RCT) in endodontic. Pain accompanying fear and anxiety due to endodontic treatment can be reduced by anesthetic techniques. The present study aims to compare the effect of articaine versus lidocaine local anesthesia for inferior alveolar nerve block (IANB) and long buccal nerve block on pain during RCT. METHODS: Twenty patients diagnosed with symptomatic irreversible pulpitis of mandibular posterior tooth were selected. The patients randomly received either cartridge of lidocaine or articaine using IANB and long buccal nerve block. The patients were randomly divided into two groups of ten. Group 1: patients received IANB and long buccal nerve block 2% lidocaine with 1:100000 epinephrine. Group 2: patients received IANB and long buccal nerve block with 4% articaine with 1:100000 epinephrine. Before the Injection, the patient received all information about the visual analysis scale (VAS). Pain was evaluated using VAS scale in numberic value 1 to 10 number. The pain was evaluated at three different stages: before administration of LA, after immediate access opening, and after immediate obturation procedure. Data were analyzed using various suitable statistical tests. RESULT: The mean value of efcacy of pain before administration of local anesthesia (LA) was 8.50 ± 0.97 for lidocaine and 8.30 ± 0.48 for articaine had no signicant difference. A signicant difference was observed at two different duration after immediate access opening and after immediate obturation where articaine has a lower mean value 3.60 ± 1.08 and 1.60 ± 0.17 respectively (P>0.05) as compared to the mean value of lidocaine 4.10 ± 1.10 and 1.60 ± 0.17 respectively Conclusion: Within the limitations of the study, in cases of symptomatic irreversible pulpitis articaine 4% did not alleviate pain much and showed better anesthetic efcacy than 2% lidocaine with IANB and long buccal nerve block.

The purpose of this prospective, randomized, double blind study was to compare the onset and duration periods of pulpal anesthesia using 2% lidocaine with 1:100,000 epinephrine, 4% articaine with 1:100,000 epinephrine and 4% articaine with 1:200,000 epinephrine in inferior alveolar nerve block (IANB). Thirty subjects received 1.8 mL of each of the three local anesthetic solutions in IANB. Onset and duration periods of pulpal anesthesia were determined using electric pulp stimulation. The mean time of onset of pulpal anesthesia was 8.7, 7.4 and 7.7 min and the mean duration of pulpal anesthesia was 61.8, 106.6 and 88.0 min for 2% lidocaine with 1:100,000 epinephrine, 4% articaine with 1:100,000 epinephrine and 4% articaine with 1:200,000 epinephrine, respectively. For onset, there was only a significant difference between 2% lidocaine with 1:100,000 epinephrine and 4% articaine with 1:100,000 epinephrine (p=0.037). For duration, there was significant difference for all the local anesthetic solutions (p≤0.05). In conclusion, 4% articaine with 1:100,000 epinephrine exhibited faster onset and also had longest duration of pulpal anesthesia in IANB.

Background: Ketorolac has advantages over other analgesics as a pre-anaesthetic medication. Considering this in mind, the present meta-analysis aims to identify the effect of oral ketorolac premedication on the anaesthetic efficacy of Inferior Alveolar Nerve Block (IANB) in patients with irreversible pulpitis. Methods: Full-texts of eligible studies were obtained from electronic databases. The extracted data was analysed using non-Cochrane mode in RevMan 5.0 software. Relative risk [95% CI] was calculated for the success of IANB. Results: Four studies were included for the final review. The success rate of IANB on 221 patients with relative risk of 1.87 [1.36, 2.56] was statistically significant favouring ketorolac. The mean difference for VAS in 171 patients was not statistically significant {-13.55 [-33.91, 6.82]}. Conclusion: Oral ketorolac can be successfully administered as a premedication before conventional inferior alveolar nerve block for endodontic treatment for irreversible pulpitis.

This article reviews research and author experience behind Intraligamentary Local Anaesthesia (ILA) and Infiltration Local Anaesthesia (IFA) with Inferior Alveolar Nerve Block (IANB). In particular, the use of ILA with 4% articaine is discussed as an effective anaesthetic technique to replace both IANB and IFA for the purpose of tooth extraction in the posterior mandible. ILA also avoids the possible complications associated with IANB. Other advantages and some shortfalls of the ILA technique are described in relation to primary dental care. The technique for achieving ILA is described. CPD/Clinical Relevance: The ILA technique with articaine is a simple, swift and effective alternative to IANB and IFA for extraction of posterior teeth in the mandible in primary dental care. ILA has fewer potential debilitating complications than IANB and is likely to be more effective than IFA.

Abstract Objective To compare the effectiveness and complications of intraligamentary anesthesia (ILA) with conventional inferior alveolar nerve block (IANB) during injection and dental treatment of mandibular posterior teeth. Materials and methods In this randomized, prospective clinical trial, 72 patients (39 males, 33 females), scheduled for dental treatment of mandibular posterior teeth, were randomly allocated to ILA group (n = 35) received ILA injection or IANB group (n = 37) received the conventional IANB. Our primary outcome was to assess pain and stress (discomfort) during the injection and dental treatment, using the numeric rating scale (NRS) from 0 to 10 (0 = no pain, 10= the worst pain imaginable), whereas recording 24-h postoperative complications was our secondary outcomes. Results Patients in ILA group reported significantly less pain during injection when compared with IANB group (p = 0.03), while pain during dental treatment was similar in both groups (p = 0.2). Patients in both groups also reported similar law values of discomfort during treatment (p = 0.7). Although no signs of nerve contact or any other postoperative complications were observed, five patients in IANB group (none in ILA group) reported temporary irritations. Conclusion This study showed equivalent effectiveness of both intraligamentary anesthesia and conventional inferior alveolar nerve block, for pain control during routine dental treatment of mandibular posterior teeth. Nevertheless, ILA showed significantly less pain during injection. No major postoperative complications in both groups were observed. Clinical relevance ILA could be considered as an effective alternative for routine dental treatment. Trial registration NCT04563351
