“…The dental pulp is an oral tissue composed of multiple neural elements. In modern dentistry, local anesthesia of pulpal tissue during treatment has been proven to block the pathway of pain sensation (or transduction) ( 3 ). But, drug injection itself can intensify anxiety and fear, particularly in younger patients ( 4 ).…”

Objective: The purpose of this study was to investigate the pulpal effect of diode low-level laser therapy (LLLT) of 810 nm on the alleviation of pain in patients requiring dental procedures. Methods: The current study was a double-blind randomized clinical trial carried out on twenty participants. The electric pulp testing (EPT) was recorded at baseline. Patients were randomly divided into sham laser and laser group respectively receiving low-level laser with placebo and active probes. Low-level laser at 810 nm, 200 MW constant power, 30s irradiation time and energy dose of 6 J was used. The electric pulp testing (EPT) method was again adopted to assess the rate of induced anesthesia. Laser and sham laser treatments were carried out in two different sessions with a one-week interval to ensure avoiding the potential false placebo results. Data were analyzed in SSPS-24 using Chi-square test and t-test. The p-value was set at 0.05. Results: A low-level laser at 810 nm significantly alleviate EPT-induced pain compared to the pain before laser irradiation (P≤0.001). While the difference of EPT-induced pain before and after sham laser irradiation was not significant in control group (P>0.05). There was no correlation between the anesthetic effects of a laser application at 810 nm and other variables including age and gender (P>0.05). Conclusion: An 810 nm low-level laser is a powerful device for induced anesthesia applications in patients requiring dental procedures. It also lessens the patients’ fear of dental procedures.

“…Moreover, the local anesthesia which was applied using 2% lidocaine with epinephrine 1/80,000 in the present study could play an important role on the bleeding time. Chu et al demonstrated that the use of local anesthesia based on lidocaine and epinephrine decreases the pulpal blood flow and may protect the dental pulp by attenuating the increase in pulpal blood flow caused by tooth preparation [ 41 ]. Moreover, it is known that the infiltration anesthesia is used successfully in the maxillary teeth but is less effective in the mandibular molar regions due to the density of bone [ 42 ]; therefore, block anesthesia was used in the present study for the mandibular molar regions.…”

The Influence of Carious Lesion and Bleeding Time on the Success of Partial Pulpotomy in Permanent Molars with Irreversible Pulpitis: A Prospective Study

et al. 2023

This prospective study aimed to evaluate the success rate of partial pulpotomy using mineral trioxide aggregate (MTA), in permanent molars with symptomatic irreversible pulpitis. Moreover, this study aimed to investigate the effect of carious lesion depth and activity and bleeding time on the outcome of partial pulpotomy. Forty permanent molars with deep and extremely deep carious lesions clinically diagnosed with symptomatic irreversible pulpitis were included. The status of the carious lesion was evaluated clinically and radiographically to determine its activity (rapidly or slowly progressing) and depth (deep or extremely deep). A partial pulpotomy was performed and MTA was used. Clinical and radiographic analysis were performed at 3, 6 and 12 months. Chi-square analysis and Fisher’s exact test were used. Scanning electron microscope and energy dispersive X-rays were used to investigate the crystalline structures and their chemical composition onto MTA surfaces after immersion in several conditions. The partial pulpotomy was 88.9% successful, with no significant difference in outcome between deep and extremely deep carious lesions (p = 0.22) or between rapidly and slowly progressing lesions (p = 0.18). Nevertheless, all failed cases were associated with rapidly progressing lesions and extremely deep lesions. All failures occurred when the bleeding time was more than 3 min (p = 0.10). Different crystalline structures were detected on MTA surfaces, with higher calcium percentages in PBS conditions. Within the limitations of the present study, favorable results demonstrated that MTA might be recommended as a suitable agent for partial pulpotomy in permanent molars with irreversible pulpitis. The depth and activity of the carious lesion as well as the bleeding time are important factors in the success of partial pulpotomy treatment. The prolonged bleeding time and the extremely deep rapidly progressing caries could be related with the failure cases in partial pulpotomy treatment of irreversible pulpitis.

“…As mentioned earlier, the 1-per-mil tumescent solution may have shown unfavorable effect for the flap surgery; especially on the perforator-based skin flap. 6 It is believed that epinephrine causes vasoconstrictive effect, 11,12 and perhaps leads to flap necrosis, especially when the large flap is raised immediately after injection. 9 However, Atabey et al 13 contradictorily stated that the application of lidocaine with 1:400,000 and 1:800,000 epinephrine concentrations were found to be safe on the rats' skin flap and delaying raising time of the flaps appeared to not change the rate of flap necrosis.…”

The aim of the study is to compare the systematic injection patterned-technique of 1-permil tumescent solution versus the random patterned-technique. Several incidences of perforator flap necrosis have been encountered with tumescent technique. Among the possible causes, the most probable cause is the injury of perforator artery due to the multipassing needle injections. Thus, an evaluation regarding the needle injection pattern needs to be done in order to avoid necrotic flap incidence. A randomized controlled experimental study was conducted on both groins of 20 healthy Wistar stained-Rattus novergicus weighing 220 to 270 g. A comparison of a systematic injection pattern and a random injection pattern was performed. Three mL of 1-per-mil tumescent solution was injected subcutaneously before elevation of the islanded groin flap. Clarity of the operative field along with the size of the pedicle were recorded. The photos of survival area of the skin flap on postoperative day 7 were analyzed using Analyzing Digital Images. Totally bloodless operative field was observed in all subjects. Three out of 19 flaps in group A (15.78%) and 4 out of 18 flaps in group B (22.22%), were found to be necrotic, either total or partial. No significant difference (P. 0.05) was found between the injection technique groups, in terms of flap necrosis. Although the 1-per-mil tumescent technique is advantageous in a way that it provides a totally bloodless operative field, the systematic injection patterned-technique was not found to be more superior compared to the custom random patterned-multi-passing needle injection technique.
