BACKGROUND: Root canal therapy (RCT) and pulpotomy are two common treatment modalities for managing dental pulp infections, but their comparative effectiveness in terms of patient outcomes remains unclear. This root canal therapy (RCT) aimed to assess and compare patient outcomes between teeth treated with traditional RCT and pulpotomy. MATERIALS AND METHODS: In this single-center RCT, a total of 120 patients presenting with symptomatic dental pulp infections were randomly assigned to either the RCT group or the pulpotomy group...

AIM: This systematic review was conducted with the purpose of analyzing the effects of root-end sealers in endodontic re-treatment cases and comparing calcium-based sealers with sealers, which were resin-based. METHODOLOGY: We conducted this review based on the principles of Cochrane systematic type of studies and also based on guidelines of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). An exhaustive search was conducted across PubMed, Medline, and Embase databases for the studies, which were based on root end sealers in cases of endodontic re-treatments...

OBJECTIVE: examination of the influence of chemical composition changes on the ability of sealers to withstand a pull-out test. MATERIALS AND METHODS: Fifty distal or palatal canals of extracted teeth were prepared by Dc Taper files. The teeth were divided into five groups: AH Plus, BJM RCS, Total Fill BC,AH Plus Bioceramic and a group with Gutta Percha with no sealer added. Ten days after obturation, each cone was subjected to the "pull-out test" with the Shimadzo Universal Testing Machine until it was torn or removed from the canal...

Corona mortis (CM) is an anastomotic vessel between the inferior epigastric or external iliac vessels and the obturator or internal iliac vessels. The Latin meaning of it is 'crown of death' which corresponds to massive haemorrhage caused by injury to this vessel during surgery. The incidence of this vessel is around 50% in the hemipelvis. We are presenting an intraoperative video of a right laparoscopic totally extraperitoneal mesh hernioplasty demonstrating a CM artery in the right hemipelvis. Care was taken to prevent injury to this vessel...

INTRODUCTION: Pathological conditions such as internal root resorption (IRR) may complicate root canal filling. This study aimed to evaluate and compare the obturation quality by measuring the percentage of obturation volume (POV) in root canals with artificial IRR obturated with different materials and techniques using cone beam computed tomography (CBCT). METHODS: Forty single canal extracted mandibular premolars were decoronated to standardize their length to 14mm...

Speech is the most basic yet invaluable mode of expression for an individual. Alterations in speech can have vast effects on the psychological well-being of a person, hampering social interactions. Congenital or traumatic defects of the hard and soft palate result in velopharyngeal dysfunction, which often results in abnormal and aberrant speech. Apart from these, it is also a common outcome following surgical repair of cleft palate. Prosthodontic management of such cases with velopharyngeal obturators to improve speech and function is well documented and known to give optimal results...

Skeletal tuberculosis is a rare form of extrapulmonary tuberculosis. Due to non-specific clinical features, these cases are often diagnosed very late, ultimately affecting treatment outcomes. The present case is a very rare case of tuberculosis of the iliac bone and acetabulum with iliopsoas, obturator internus, and obturator externus abscesses in an Indian female. She reported pain in her right hip and a limp. It was a difficult diagnosis, especially due to the rare involvement of bones and muscles in the absence of any lesions in the lungs...

Locally recurrent rectal cancer (LRRC) involving the lateral pelvic sidewall requires a complex approach to maximize the likelihood of R0 resection, which is the only predictor of survival. The purpose of this report is to describe a novel technique to resect a localized lateral pelvic sidewall LRRC. A 63-year-old male patient was referred for a 15-mm LRRC near the right internal iliac vessels. Endoscopic ultrasound and magnetic resonance imaging excluded any involvement of the pelvic colon or residual rectum...

Cone beam computed tomography (CBCT) technology is increasingly utilized in the head and neck region and is valuable in treatment planning for cleft palate patients, potentially enabling the creation of 3D-printed obturators to assist with feeding and speech. This technical report investigates the feasibility of using data from a 360-degree CBCT scan to accurately produce a cleft palate obturator and assesses whether a lower-dose 180-degree CBCT scan can achieve a comparable result. A simulated cleft palate was crafted on a dehydrated human skull, which was then scanned using both 360-degree and 180-degree CBCT scanning protocols...

INTRODUCTION: The final step of irrigation has been considered to of increase the bonding strength of filling material to dentin. This study investigated the impact of three final-step irrigation methods on the endodontic sealer bond strength to dentin by using a micro push-out test. MATERIALS AND METHODS: Palatal roots of human maxillary molars were cleaned and shaped and randomly divided in six groups (n=15) according to the final-step irrigation method and the type of root canal sealer used...

Endodontic management of teeth afflicted with pulp canal obliteration faces a challenge due to the heightened risk of complications including excessive wear, perforation, and suboptimal chemomechanical preparation. This report aims to elucidate the clinical endodontic strategy employed in addressing pulp canal obliteration after a history of dental trauma and an associated periradicular lesion in an upper lateral incisor. A patient visited the dental emergency department with symptoms of apical swelling, acute persistent pain, and discoloration of tooth 22...

INTRODUCTION: The current study aimed to compare the quality of root canal obturation performed with cold lateral condensation with other obturation techniques. MATERIALS AND METHODS: Diverse Search was conducted using six electronic/academic databases following PICOS (i.e. population, intervention, control, outcomes, and study design) strategy: (P) Extracted mature permanent teeth; (I) Obturation techniques except for cold lateral condensation; (C) Cold lateral condensation tyechnique; (O) Quality of root canal obturation; and (S) In vitro studies assessing parameters using micro-computed tomography...

Background Removing gutta-percha manually can be a challenging task, especially when addressing densely packed root-filling material, particularly in cases where resin-based sealers are employed for obturation. The use of nickel-titanium (NiTi) rotary instruments not only effectively shapes the root canal but also efficiently removes the endodontic filling from the curved canal during retreatment. Hence, incorporating rotary NiTi instruments in retreatment cases can alleviate fatigue for both patients and operators...
