Evaluation of Pain Following the Use of Different Single-file Glide Path Systems: A Randomized Clinical Trial

INTRODUCTION

This study aimed to evaluate postoperative pain intensity following glide-path preparation using the ProGlider (PG) and WaveOne Gold Glider (WOGG) systems in asymptomatic teeth with necrotic pulp and periapical lesions.

METHODS

In this randomized clinical trial (ClinicalTrials.gov ID: NCT05955742) maxillary and mandibular molars with asymptomatic apical periodontitis of 78 patients (age, 18-65 years) were included. The patients were randomly divided into 3 groups: control (n = 26), PG (n = 26), and WOGG (n = 26). All the systems were used according to the manufacturer's instructions, and all the root canal treatments were completed by a single operator within 2 sessions. Postoperative pain was assessed using a numerical rating scale at 6, 12, 18, 24, 48, and 72 hours. Analgesics administered and abscess formation were also recorded. Statistical analyses were performed using the Mann-Whitney U, Bonferroni Dunn, Friedman, Chi-square, and Fisher exact tests.

RESULTS

The postoperative pain at 12 and 18 hours was lower in the WOGG group than in the other groups (P < .05). The postoperative pain scores at 6 and 24 hours were higher among women than among men (P < .05). The highest postoperative pain scores were observed at 6 hours (P < .05).

CONCLUSIONS

The WOGG glide-path file system was associated with less postoperative pain than the other systems. Abscess formation and analgesic use were higher in the PG group than in the other groups. Postoperative pain was greater in women than in men.

Effect of intracanal cryotreated sodium hypochlorite on postoperative pain after root canal treatment - A randomized controlled clinical trial

Introduction

The postendodontic pain is caused by either microbial, mechanical, or chemical factors or combinations of these. The incidence of postoperative pain ranges from 1.4% to 53%. The management of postendodontic pain is a crucial factor for a successful practitioner. Cryotherapy is a new therapeutic option applied in sports medicine and surgery for the management of pain and for postoperative care.

Aim

The purpose of this study was to evaluate and to compare the effect of intracanal cryotreated sodium hypochlorite and room temperature sodium hypochlorite on postoperative pain after root canal treatment.

Materials and Methods

Sixty-four patients were selected according to inclusion criteria and baseline score was recorded. After obtaining consent, the access cavity was opened under local anesthesia. On the completion of cleaning and shaping, the patients were randomly divided into two groups: Group A: Normal Room temperature NaOCl and Group B: Cryotreated NaOCl (2°C-4°C), each of the canals further received 20 ml of the respective irrigants based on the groups allocated. The final rinse was done with saline, and canals were dried and obturated in the same appointment. Postoperative visual analogue scale pain levels were recorded at 6, 24, and 48 h over the phone.

Results

The data were analyzed using SPSS software. The results of the present study showed that cryotherapy group showed a statistically significant reduction in postoperative pain levels at all tested time intervals and reduced analgesic intake at 6 h postoperatively.

Conclusion

Cryotherapy could be used as an easy and cost-effective technique for controlling postendodontic pain in the day-to-day clinical practice.

Effect of calcium hydroxide mixed with lidocaine hydrochloride on postoperative pain in teeth with irreversible pulpitis and symptomatic apical periodontitis: a preliminary randomized controlled prospective clinical trial

OBJECTIVES

To investigate the effect of calcium hydroxide mixed with lidocaine HCl on postoperative spontaneous pain.

MATERIALS AND METHODS

Sixty patients having irreversible pulpitis and symptomatic apical periodontitis with a preoperative spontaneous pain and percussion pain which was more than 50 on a visual analogue scale (100 mm VAS) were included in this study. After the preparation of the root canals, the patients were randomly distributed into two groups according to the calcium hydroxide vehicle, control group (mixed with saline) and calcium hydroxide mixed with lidocaine HCl (n = 30). Postoperative spontaneous pain scores were recorded by a VAS every day for a week. Data were analysed using one-way analysis of variance, chi-squared test and Mann-Whitney U tests (p = 0.05).

RESULTS

The calcium hydroxide mixed with lidocaine HCl group resulted in significantly less pain compared with the calcium hydroxide mixed with saline group during days 1 to 4 (p < 0.05). There were no significant differences between the groups in terms of postoperative percussion pain levels (p > 0.05).

CONCLUSION

Within the limitations of this study, it can be concluded that the calcium hydroxide mixed with lidocaine HCl can be beneficial in reducing postoperative pain in teeth with irreversible pulpitis and symptomatic apical periodontitis.

CLINICAL RELEVANCE

The calcium hydroxide mixed with lidocaine HCl can be beneficial in reducing postoperative pain in teeth with irreversible pulpitis and symptomatic apical periodontitis.

Efficacy of Prophylactic use of Antibiotics to Avoid Flare up During Root Canal Treatment of Nonvital Teeth: A Randomized Clinical Trial

OBJECTIVES

Flare-up during root canal treatment of non vital teeth is a common clinical incident. The aim of the present study was to assess the effect of prophylactic use of antibiotics to avoid flare up during root canal treatment of the teeth having asymptomatic necrotic pulp.

MATERIALS AND METHODS

A randomized double blind clinical trial with parallel design was conducted on 100 subjects with asymptomatic non vital teeth. They were randomly divided into two groups. The first group (50 participants) was given two gram amoxicillin one hour before the first visit of root canal treatment; the second group (50 participants) did not receive any treatment (control group). In both groups, root canal treatment was performed in two visits. The flare up was assessed by the pain visual analogue scale and based on the swelling criteria. The data were processed and analyzed using SPSS statistical software 17. A p-value of 0.05 or less was considered statistically significant.

RESULTS

A total of 80% of participants in the experimental group had flare up while 12% of participants had flare up in the control group. Prophylactic Amoxicillin had no effect on inter-appointment flare up (p > 0.05). There was no relationship between flare up and patient's age, gender and tooth type (p > 0.05).

CONCLUSION

Prophylactic use of Amoxicillin in asymptomatic non vital teeth before root canal treatment had no effect on the incidence of flare-up.
