Effect of continuous ultrasonic irrigation on postoperative pain in mandibular molars with nonvital pulps: a randomized clinical trial

Abstract

A significant difference was observed between CUI and syringe irrigation on the first postoperative day following chemo-mechanical preparation. However, the benefit observed was not clinically relevant.

Association between dental anxiety and intraoperative pain during root canal treatment: a cross‐sectional study

“…Many studies have investigated post‐operative and intraoperative pain in patients undergoing root canal treatment (Sathorn et al , Segura‐Egea et al , Martín‐González et al , Alonso‐Ezpeleta et al , Middha et al , Gomes et al ), but few have analysed the relationship between anxiety and intraoperative endodontic pain (Maggirias & Locker , Watkins et al ). The present study is the first using multivariate logistic regression to analyse the correlation between dental anxiety and intraoperative pain, including age, gender, tooth type, endodontic diagnosis, medicaments intake and pre‐operative pain as possible confounding factors.…”

What's new for the clinician? Summaries of and excerpts from recently published papers

“…Postoperative pain is usually attributed to mechanical, chemical and microbial causes. 1 The bacterial flora is also primarily responsible for pulpal and periradicular diseases. Thus, eradication of bacterial population from the root canal or at least its significant reduction is essential for the successful management of endodontically involved teeth.…”

“…Thus, eradication of bacterial population from the root canal or at least its significant reduction is essential for the successful management of endodontically involved teeth. 1 Mechanical instrumentation techniques, in isolation, are incapable of rendering the root canals free of bacteria. The intricacies of the root canal system hinder its complete debridement as these areas are inaccessible to mechanical instrumentation and continue to harbour bacteria, necrotic tissue and debris.…”

“…Recent data from the International Diabetes Federation (IDF) estimates that 7 % of South Africans between the ages of 21 and 79 years have diabetes. 1 Based on the latest population estimates for South Africa, this means that 3.85 million South Africans in this age group may have diabetes. However, these statistics only shed light on the surface of a much deeper problem.…”

“…In 2010, the prevalence of type 2 diabetes in South Africa was estimated at 4.5 %. 1 Thus, a 155 % increase in six years! The majority of people with diabetes can be classified as having Type 1 or Type 2.…”
