Effect of injection site pre-cooling on pain perception in patients attending a dental camp at Life Line Express: A split mouth interventional study

Abstract

Background and aimTo determine the effect of pre-cooling injection site on pain perception in patients attending a dental camp at lifeline express, Habibganj.MethodsA split mouth interventional study assessed the effect of pre cooling the injection site in patients (n=33) requiring bilateral buccal infiltration prior to extraction. One side of the patient’s mouth received the intervention after the injection site was pre cooled with ice for 3 minutes along with topical Lidocaine, while the other mouth side of the same patient received only topical Lidocaine and served as control group. A structured proforma assessed the demographic characteristics and risk factors that influence pain perception in patients. Mann-Whitney U tests and Wicoxon rank sum test were used for statistical analysis. Statistical significance was defined at P<0.05.ResultsThe results revealed a significant difference in pain perception between control and intervention group as assessed using both Heft-Parker Visual Analog Scale (median score 3.0 and 1.0) and Sound Eye Motor scale (median score=1.0 and 0.0) (P<0.01). For both the scales the assessed and self reported variables Gender, Location, Chief Complaint, Region and Arch were found to be statistically significant.ConclusionPre cooling injection site reduced pain perception in patients.

Audiovisual Distraction: A Pricking Pain Reduction Modality among Ladies Receiving Intraoral Injections

“…This also augments our intra-group observation suggesting that older age group might have higher pain threshold. This result is similar to study conducted by Bahaduria et al 17 , who revealed great reduction in the elderly age group.…”

“…The results of the present study are in line with the split mouth interventional study conducted by Bhadauria et al 17 They used pre-cooling agent to distract mind of 33 adult patients to determine its effect during buccal infiltration. Three minutes application of ice was applied on one side of the mouth (in place of audiovisual aid in the present study) and topical anesthesia was applied on the other half.…”

Effect of precooling on pain during local anesthesia administration in children: a systematic review

“…After removal of the duplicate articles, a total of 1178 records were screened for title and abstract. Full texts of 10 potentially relevant papers were evaluated, of which 4 were excluded [13,[15][16][17] (Reasons for exclusion is provided in Table 1). Consequently, 6 studies were included in this final systematic review [8,[18][19][20][21][22].…”

Comparison of Pain Perceived by Patients Undergoing Intra Oral Local Anesthesia Using Different Needle Gauges

“…This was the same in the study by Kaur et al 7 and Janani and Kumar 15 where no significant differences were found between pain scores for men and women receiving dental anesthesia. However another study shows that gender has an important role to play in pain perception with women more likely to experience more pain with the same stimulus than men 16 .…”
