Inferior Alveolar Nerve Block Injection Pain Using a Computer-Controlled Local Anesthetic Device (CCLAD): A Prospective, Randomized Study

A Comparative Analysis of the Efficacy of Local Anesthetics and Systemic Anesthetics in the Red-Headed Versus Non-Red-Headed Patient Population: A Comprehensive Review

Researchers have found that individuals with red hair often require higher doses of anesthetic medications to achieve the same level of pain relief or sedation compared to people with other hair colors. This review investigates the effects of local and systemic anesthetics in individuals with red hair compared to the general population. Focusing on both local and systemic anesthesia, this research aims to elucidate any distinctive responses or complications among the red-haired demographic. Utilizing a systematic review approach, we analyzed a wide array of previous research papers published over the last two decades to gather relevant data. Our findings suggest that people with red hair may exhibit variations in their response to both local and systemic anesthesia compared to non-red-haired individuals, indicating the necessity for tailored anesthetic approaches in clinical settings. Previous studies have found that individuals with red hair, as well as those with the corresponding melanocortin-1 receptor (MC1R) mutations, exhibit a greater resistance to the effects of systemic and local anesthetics. This review provides valuable insights that could help healthcare professionals optimize anesthetic management and improve patient outcomes, particularly for those with red hair.

Patient discomfort and intensity of intraseptal anesthesia of computer-controlled articaine/epinephrine delivery for scaling and root planing

OBJECTIVES

The primary aim was to assess the pain during intraseptal anesthesia (ISA) administration, as well as during and after scaling and root planing (SRP). The secondary aims pertained to comparing the pain in different jaw regions and evaluating the factors affecting pain during ISA administration, during and after SRP.

MATERIAL AND METHODS

ISA was obtained with three different doses of 4% articaine with 1:100,000 epinephrine (4%Ar + Ep) in 360 patients. The pain levels were measured using the visual analogue scales (VAS) for pain intensity during ISA administration (VASa), during SRP (VASi), and after SRP (VASp). These findings were then correlated with periodontal parameters. Regression analysis was performed for pain during ISA, during and after SRP.

RESULTS

Anesthesia administration was painful in 80.8% of cases. VASa negatively correlated with pocket depth (PPD). VASi showed no dose-dependency, except in mandibular premolars. VASi negatively correlated with the clinical attachment level (CAL). VASp positively correlated with PPD and CAL. Positive bleeding on probing reduced the chance of pain during ISA administration. Longer anesthesia duration and wider anesthetic field (orally) increased the prospects of painless SRP.

CONCLUSIONS

No dose-dependent differences were found regarding patient discomfort and pain intensity of ISA delivery of 4%Ar + Ep for SRP.

CLINICAL RELEVANCE

The pain during ISA administration was mild and well tolerated regardless of the anesthetic dose. A lower intensity of pain during SRP can be expected in patients with greater CAL. Post-treatment pain can be anticipated after SRP in the regions with greater PPD and CAL.

The effect of pre-anesthesia with a needle-free system versus topical anesthesia on injection pain of the inferior alveolar nerve block: a randomized clinical trial

OBJECTIVE

The aim of this study was to compare the effectiveness of pain control between a needle-free system and topical anesthesia applied prior to inferior alveolar nerve block (IANB).

MATERIALS AND METHODS

The present study was designed as a randomized controlled cross-over clinical study on 60 children (aged 6 to 12 years) requiring dental treatment with IANB in bilateral mandibular molars. As pre-anesthesia, topical anesthesia (TA) was applied on one side and the Comfort-in™ injection system (CIS) on the other side in two separate sessions before IANB. The injection pain during IANB, at both the needle insertion and solution deposition phases, was analyzed using the Wong-Baker Faces Pain Rating Scale (PRS) and the Face, Legs, Activity, Cry, Consolability Scale (FLACC). The data were analyzed using the Wilcoxon signed-rank test, Spearman correlation, and Mann-Whitney U test.

RESULTS

There were statistically significant differences between TA and CIS in subjective and objective pain evaluations during both the needle insertion and solution deposition. The use of a needle-free system in pre-anesthesia yielded a significant decrease in subjective and objective pain scores (p < 0.001). No statistical difference was found between TA and CIS in terms of patient preference, but patient preference for CIS was significantly higher in older patients (p < 0.01).

CONCLUSIONS

It was determined that the use of a needle-free system in pre-anesthesia yielded a decrease in injection pain of IANB.

CLINICAL RELEVANCE

Pediatric dentists should be aware of the new injection system in order to decrease the level of injection pain.
