“…Numerous pediatric dental services require the administration of local anesthetic, which acts to decrease the sympathetic activation brought on by the dental operation. Local anesthetics are regarded as the foundation of pain control in children that need to undergo dental treatments such as extractions, pulpotomies, or pulpectomies [1].…”

BACKGROUND: Local anesthetics are the gold standard for pain control in dentistry. Most patients still view the “needle” as a source of anxiety and disruptive behavior rather than relief. The patient’s cooperation and comfort level will increase with the administration of painless local anesthetic injection using appropriate technique. The purpose of this study was to assess the patient cooperation and behavior after receiving local anesthesia injection and to compare patients’ acceptance and preference of needleless NumBee anesthetic delivery device to conventional dental syringe. MATERIALS AND METHODS: 30 non-fearful 6-8-year-olds who had never been to the dentist were selected for the study using a split-mouth design. They underwent a simple class I restoration on both mandibular permanent first molar teeth in two separated dental visits. The Frankl behavior rating scale was used to assess patient behavior following injection. Patients expressed their preference and acceptance of the used syringes by answering a questionnaire. RESULTS: After injection by either method, 25 patients had Frankl behavior rating score of 4. Patients that had a negative response with the traditional method, showed a score of 2, following NumBee injection (p=0.035). CONCLUSION: Patients accepted both methods, and NumBee may induce less fear, with minimum stinging and unpleasant taste.

ObjectivesThis study aimed to assess the effect of needle insertion angle on pain during labial infiltration anesthesia in the anterior maxillary region.Material and MethodsIn this parallel‐design randomized clinical trial, participants were randomly assigned to four groups for labial infiltration anesthesia of the anterior maxilla. Local anesthesia was performed with needle orientation parallel to the longitudinal axis of the tooth using a conventional syringe (Syringe‐0), needle at α angle with a conventional syringe (Syringe‐α), computer‐controlled local anesthetic delivery (CCLAD) device parallel to the longitudinal axis of the tooth (CCLAD‐0), and CCLAD at α angle (CCLAD‐α). The heart rate (HR), blood pressure (BP), and respiratory rate (RR) of participants were measured before needle insertion, immediately after needle insertion, and immediately after the injection by a vital signs monitor. The level of pain experienced by participants was quantified using a numerical rating scale (NRS). Data were analyzed by repeated‐measures ANOVA and regression models (α = 0.05).ResultsThirty‐six participants aged from 21 to 60 years, with a mean age of 35.36 years were recruited. The mean pain scores were 7.44, 4.67, 2.89, and 0.67 in groups Syringe‐0, Syringe‐α, CCLAD‐0, and CCLAD‐α, respectively (p < 0.001). Age and sex had no significant effect on pain scores (p = 0.914 and p = 0.702, respectively). The four groups had no significant difference in vital signs (p > 0.05).ConclusionsInjection at an α angle and the application of CCLAD can be used in clinical practice to decrease the pain experienced by participants during labial infiltration anesthesia of the anterior maxilla.Trial RegistrationIranian Registry of Clinical Trials: IRCT20230719058849N1.
