Comparison of The Effectiveness of Intraligamentary and Mandibular Anesthesia on Mandibular Molar Teeth

Comparison of The Effectiveness of Intraligamentary and Mandibular Anesthesia on Mandibular Molar Teeth: A Randomized Clinical Study

This study aimed to compare the effects of mandibular and intraligamentary anesthesia techniques on pain scores during restorative treatment of permanent mandibular molars in pediatric patients. Additionally, comparing the anesthesia techniques in terms of injection pain, the success of anesthesia, postoperative complications, and the subjects' preference was planned.

This randomized, controlled, cross-over, single-blind, split-mouth study was conducted on 78 subjects aged 6 to 12 years. Subjects with enamel-dentin caries on the bilateral permanent mandibular molar were included.

Study Overview

• Status: Completed
• Conditions: Anesthesia, Local
• Intervention / Treatment: Procedure: Intraligamentary anaesthesia; Procedure: Mandibular anaesthesia

Detailed Description

First, the subjects who met the inclusion criteria in the study were included in 2 study groups according to age, gender, dental experience, DMFT / dmft values, and ICDAS II and radiographic evaluation criteria. Two different anesthesia techniques were applied to the right / left permanent first molar teeth of the patients included in the study, with an interval of one week. The subjects have been divided into two groups as 39 subjects were Group 1 received intraligamentary anesthesia in the first visit, and 39 subjects were Group 2 received mandibular anesthesia in the first session. The pain perception rates of the patients during the injection and treatment phases were recorded subjectively using a visual analog scale and Wong-Baker FACES pain rating scale. Heart rate and arterial oxygen saturation were determined as the physiological parameters. The quality of anesthesia and success were evaluated by the operation at the end of each visit. Complications (pain, raised teeth, hematoma, trauma due to lip/tongue bites, swelling, infection, and bleeding) were explained to the patients after anesthesia. They were asked to take note of the complications they encountered. Postoperative complications were recorded by calling the cases 1 day after the 1st and 2nd visits. At the end of the second visit, anesthesia preference of the patient was asked and recorded.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Intraligamentary Anaesthesia; Before the restorative treatment of mandibular first molar, SOPIRA® 30 gauge extra-short cartridge needle attached to the tip of the SOPIRA® Citoject (SOPIRA® Heraeus Kulzer, Hanau, Almanya) pressure injector will be inserted into the periodontal sulcus 1-2 mm until resistance. The needle will be at an angle of 30 degrees to the long axis of the tooth. As recommended by the manufacturer, a total of 0.36 ml (mesiobuccal and distobuccal) 4% articaine solution containing 1:100,000 epinephrine (Ultracaine DS forte cartridge, Sanofi-Aventis GmbH, Almanya) will be injected slowly over 42 seconds by pressing the dosing lever 3 times for each root. If the anaesthesia will be failed, we would use the 4-point IL injection by injecting the mesiolingual sulcus and distolingual sulcus with the same technique.	Procedure: Intraligamentary anaesthesia; one tooth anaesthesia by 2 or 4 points intraligamentary injection; Other Names: 2 or 4 points intraligamentary injection
ACTIVE_COMPARATOR: Mandibular Anaesthesia; Before the restorative treatment of mandibular first molar, inferior alveolar nerve block will be provided using the direct standard method. The 27 gauge needle of a 2ml disposable plastic syringe (Ayset, Adana, Turkey) enters from the intersection of the internal oblique edge and the midline of the pterygomandibular raphe, and 1 ml of 4% articaine solution containing1:100,000 epinephrine (Ultracaine DS Forte ampul, Sanofi-Aventis GmbH, Almanya) will be injected slowly in 60 seconds. 15 minutes after the injection the anaesthesia of the lip/tongue will be checked by probing the labial mucosa of the ipsilateral canine tooth.	Procedure: Mandibular anaesthesia; Inferior alveolar nerve block by direct standart method; Other Names: Inferior alveolar nerve block

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The measurements of dental pain using Visual Analogue Scale	Subjective pain perception scores during the intervention using Visual Analogue Scale containing Numeric Rating Scale (0-10, where 0 means no pain/best, 10 - worst possible pain)	Immediately after the working with a low-speed rotary instrument on dentin
The measurements of injection pain using Visual Analogue Scale	Subjective pain perception scores after the local anesthetic injection using Visual Analogue Scale containing Numeric Rating Scale (0-10, where 0 means no pain/best, 10 - worst possible pain)	Immediately after the local anaesthetic injection
Measurement of the pain perception during the dental procedures using Wong Baker FACES pain rating scale.	Subjective pain perception scores using Wong Baker Faces pain rating scale (Face 0: it does not hurt/best, Face 2: it hurts a little, Face 4: it hurts a little more, Face 6: it hurts more, Face 8: it hurts a lot, Face 10: it hurts a lot/worst)	Immediately after the working with a low-speed rotary instrument on dentin
Measurement of the injection pain of the local anesthesia using Wong Baker FACES pain rating scale.	Subjective pain perception scores using Wong Baker Faces pain rating scale (Face 0: it does not hurt/best, Face 2: it hurts a little, Face 4: it hurts a little more, Face 6: it hurts more, Face 8: it hurts a lot, Face 10: it hurts a lot/worst)	Immediately after the local anaesthetic injection

Change from baseline physiological parameters (arterial oxygen saturation and pulse rate) at the end of the working with a low-speed rotary instrument on dentin	Measurement of arterial oxygen saturation and pulse rate using a pulse oximeter	Baseline and immediately after the local anaesthetic injection
Practitioner's assessment of patient pain-related comfort	Practitioner's subjective records: cases who need additional mandibular anaesthesia, whose treatment is completed without a discomfort related to pain, who has a slight discomfort even though additional mandibular anaesthesia is not needed during the treatment	Immediately after the dental treatment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluate the correlation between two self reported objective pain scales	The correlation between the scores of Wong Baker Faces pain rating scale (Face 0: it does not hurt/best, Face 2: it hurts a little, Face 4: it hurts a little more, Face 6: it hurts more, Face 8: it hurts a lot, Face 10: it hurts a lot/worst) and Visual Analogue Scale for pain (0-10, where 0 means no pain/best, 10 - worst possible pain) recorded after the local anaesthetic injection in 6-12 years old patients. For the Wong Baker FACES pain rating scale, the maximum value (10) means "it hurt a lot" is the worst and the minimum value (0) means "it does not hurt" is the best outcome. For the Visual Analogue Scale for pain containing Numeric Rating Scale , while the minimum value (0) means "no pain" is the best outcome, the maximum value (10) means "worst possible pain" is the worst outcome.	Immediately after the local anaesthetic injection
