Journal Of Oral Research, 2015
Objective: To determine the effectiveness of warming anesthetic solutions on pain produced during the administration of anesthesia in maxillary dental infiltration technique. Material and Methods: A double-blind cross-over clinical study was designed. Fifty-six volunteer students (mean age 23.1±2.71 years) of the Dental School at Universidad Austral de Chile (Valdivia, Chile) participated in the study. Subjects were given 0.9ml of 2% lidocaine with 1:100.000 epinephrine (Alphacaine®; Nova DFL-Brazil) by two punctions at buccal vestibule of lateral incisor. Warm anesthesia at 42°C (107.6°F) was administered in a hemi-arch; and after one week anesthesia at room temperature (21°C; 69.8°F) and at a standardized speed was administered at the contralateral side. The intensity of pain felt during injection was registered and compared using visual analog scale (VAS) of 100mm (Wilcoxon test p<0.05). Results: The use of anesthesia at room temperature caused a VAS-pain intensity of 34.2±16.6mm, and anesthesia at 42°C a VAS-pain intensity of 15.7±17.4mm (p<0.0001). Conclusion: The use of anesthesia at 42°C resulted in a significantly lower pain intensity perception during injection compared with the use of anesthesia at room temperature during maxillary infiltration technique.

The purpose of this study is to determine the effectiveness of warming anesthesia on the control of the pain produced during the administration of dental anesthesia injection and to analyze the role of Transient Receptor Potential Vanilloid-1 nociceptor channels in this effect. A double-blind, split-mouth randomized clinical trial was designed. Seventy-two volunteer students (22.1±2.45 years old; 51 men) from the School of Dentistry at the Universidad Austral de Chile (Valdivia, Chile) participated. They were each administered 0.9 mL of lidocaine HCl 2% with epinephrine 1:100,000 (Alphacaine) using two injections in the buccal vestibule at the level of the upper lateral incisor teeth. Anesthesia was administered in a hemiarch at 42°C (107.6°F) and after 1 week, anesthesia was administered by randomized sequence on the contralateral side at room temperature (21°C-69.8°F) at a standardized speed. The intensity of pain perceived during the injection was compared using a 100 mm visual a...

Background. This study assessed the effect of cooling the soft tissue site on the perception of pain in children undergoing local anesthesia for routine dental procedures. Methods. One hundred children, 6‒14 years of age, were assigned to either of the two study groups, i.e., group 1 (infiltration) and group 2 (block anesthesia). One side of the arch served as the test side, where an ice pretreatment (IP) of the soft tissue of the injection site was carried out using a tube of ice for one minute, whereas the opposite side served as the control, where no ice pretreatment (WIP) was carried out. This was followed by the gradual injection of local anesthetic solution. The children’s pain perception was assessed by VAS, WB-FPRS and SEM scales. The data were analyzed statistically. Results. WBS, VAS and SEM scores were significantly different between the WIP and IP in both groups, indicating that ice was effective in reducing the pain perception in children. Intergroup comparison revealed...

Objectives The present study evaluates the efficacy of warm local anesthetic (37°C) administration and injections of local anesthetics at room temperature (21°C) in reducing pain during injections in children undergoing dental procedures. Materials and methods Enrolled for this split-mouth randomized clinical study were 100 children aged 5-8 years. Within the random crossover design selected for the study, each patient was randomly assigned to receive either a body or room temperature local anesthesia in the first session and the other local anesthesia on the second session. During the injection, the Wong-Baker Faces Pain Rating Scale was used as a subjective measure of discomfort, and heart rate as an objective measure. The Face, Legs, Arms, Cry, and Consolability (FLACC) scale was used to record the child's pain, based on the perception of the dental assistant. The data were analyzed using a Wilcoxon sign rank test and a paired t test. Results Based on the score of the Wong-Baker Faces Pain Rating Scale, the FLACC scale, and heart rate, the sensation of pain during dental injection in both girls and boys is statistically significantly lower at body temperature than at room temperature (p < 0.05). Conclusions It was determined that the application of local anesthetic at body temperature reduces dental injection pain significantly when compared with local anesthetics administered at room temperature. Clinical relevance The successful management of dental injection pain is an important issue during dental procedures in children. Accordingly, warming the local anesthesia prior to use in children can be recommended to clinicians.

Introduction: This study was performed to investigate the effect of topical anesthesia on pain during needle penetration and infiltration injection as well as the effect of pain during injection on success rate of anesthesia in maxillary central incisors. Methods: In a crossover double-blind study, 25 volunteers randomly received either topical anesthesia or placebo before infiltration injection with prilocaine for their maxillary central incisors in 2 separate appointments. The pain after needle penetration and during injection was separately recorded. An electric pulp tester was used to evaluate the success of the anesthetic injection. Data were analyzed by McNemar, Wilcoxon, and c 2 tests. Results: Overall for 50 injections, 72% of the teeth had successful anesthesia. No significant difference was found between placebo and topical anesthetic groups for the pain of needle penetration as well as pain during injection (P > .05). The volunteers who reported moderate-to-severe pain during injection showed no significant difference in the success rate of anesthesia compared with those with no or mild pain during injections (P > .05). Conclusions: Use of topical anesthesia had no significant effect on pain during either needle penetration or injection. Pain during injection had no significant effect on the success of anesthesia.

Background: It is crucial to manage pain during both invasive and noninvasive dental procedures because discomfort may cause patients to refuse care or put off getting it altogether. As a result, it is imperative to develop techniques that lessen pain during injections in order to keep patients from skipping dental appointments. Pain is associated with both invasive and noninvasive dental operations, although it is more commonly associated with tooth extractions, surgeries, and other invasive procedures. The use of local anaesthetics is used to prevent and manage pain, and they are thought to be the safest and most effective medications available for these purposes. Aim: To evaluate the effect of cooled topical anesthetic gel on pain perception of pediatric dental patients during the administration of local anesthesia. Material and Method: In present split mouth clinical trail, 30 children between the ages of 6 and 10 year were enrolled. Uncooled topical anaesthetic was applied in one treatment session and cooled topical anaesthesia gel in the other session prior to the administration of local anesthesia. Lignocaine 2% gel was cooled and maintained at 40 C. A small sized topical anaesthetic gel was applied on tissue using a cotton pellet for 1 minute. Similarly in next treatment session uncooled anesthetic gel was applied on injection site. The procedure was followed by infiltration injection of 2% lidocaine with 1:80,000 adrenaline (LOX* 2% ADRENALINE) using a short 27-gauge needle (Dispovan). Visual analog scale (VAS) was used to evaluate the participants’ self-reports of injection pain. Children were asked to make a mark on the line that represented their level of perceived pain intensity, and the score was recorded after the treatment. Analysis of the data was carried out using SPSS version 20.0. In all the statistical tests used in this study the significant level was pre -set at P ≤ 0.05. Result: The mean visual analog score for uncooled anesthetic gel group were 63.12 ± 4.63 and statistically significant lower score in cooled anesthetic gel group 38.23 ± 5.53 group (p< 0.001) Conclusion: The results of the present study showed application of cooled topical anesthetic gel on injection site prior to the injection of local anesthetic agent did significantly reduce the pain perceived during administration of local anesthesia for routine dental procedures.

Objective: To evaluate the efficacy of pre-cooling and the use of higher gauged needles in reducing pain during local anesthetic infiltration. Material and Methods: We conducted a split-mouth randomized controlled trial among 70 patients who require bilateral maxillary local anesthetic (LA) injections for dental treatment. After applying the topical anesthetic, each participant received four local anesthetic injections, two on buccal and two palatal sides. At each visit, the participants received one buccal and one palatal infiltration based on the randomization. On the buccal aspect, participants received LA with a 26G needle injection on one side (control) and a 31G needle (test) on the contralateral side. On the Palatal aspect, participants either received LA with a 31G needle on one side (control). In contrast, the opposite side was preceded by topical ice application (iced cotton swab) before LA with a 31G needle (test). Both the visits were spaced with a gap of 7-10 days based on the participants' feasibility. Participants were asked to rate the pain on a visual analog scale independently for buccal and palatal LA injections. Results: On the Buccal aspect, the mean pain scores were 2.74 ± 1.26 and 2.11 ± 1.26 for control and test groups, respectively (p=0.002). On the Palatal aspect, the mean pain scores were 4.14 ± 1.49 and 4.3 ± 1.80 for control and test groups, respectively (p=0.295). Conclusion: Significant lower pain scores were reported with higher gauge needles (31G) when compared to traditional (26G) needles on the buccal aspect. No significant difference was seen with pre-cooling the injection site on the palatal aspect when used with higher gauged needles (31G).
