The C-shaped canal system is an anatomical variation mostly seen in mandibular second molars, although it can also occur in maxillary and other mandibular molars. Such variation in the root canal anatomy is uncommon in mandibular first premolars and very rare in mandibular second premolars. The C-shaped canal is so named for the cross-sectional morphology of the root and root canal. The main an...

AIM To analyse the anatomy of the root canal system of maxillary premolars with three distinct roots using high-resolution computed tomography (μCT). METHODOLOGY Ten three-rooted human maxillary premolars were scanned transversally from crown to apex at 42μm intervals using a high-resolution desktop μTC system (Skyscan 1072). The images were processed and analysed for the following features: ...

INTRODUCTION The aim of this in vitro study was to compare the effect of Gates-Glidden and Peeso reamer drills on residual dentin thickness during post space preparation in order to discover which method has minimum root structure damage. MATERIALS AND METHODS Thirty extracted human maxillary premolars with bifurcations at root middle were horizontally cut 15 mm coronal to the apical end afte...

INTRODUCTION In this study, we investigated tooth-wear patterns in adolescents with either normal occlusion or Class II Division 2 malocclusion. METHODS The sample consisted of dental casts from 165 subjects that were divided into 2 groups: 115 normal occlusion subjects (mean age, 14.3 years) and 50 complete Class II Division 2 subjects (mean age, 13.9 years). Dental wear was assessed by usin...

Introduction: Pulp stones or denticles are frequently found in the dental pulp. Denticles more often occur in molars than in premolars and incisive. Materials and Methods: The study was conducted at the University Dental Clinic Centre in Skopje “St. Panteleimon”. Were included random samples 150 patients aged between 20-60 years, or 3108 teeth, meanwhile using an appropriately designed survey q...

OBJECTIVES: To determine the number and configuration of canals in permanent maxillary premolars using Cone Beam Computed Tomography (CBCT) relationship between count patient gender northwest region Pakistan. METHODS: This cross-sectional observational study was conducted at Khyber College Dentistry (KCD) Peshawar, Data collected from July 1st to 30th December 2020, 133 patient’s CBCT scans wit...

Objective: To determine whether the missing canals in endodontically treated single-rooted teeth with two-canals are present either buccal or lingual/palatal for Turkish subpopulation. Methods: High-quality cone-beam computed tomography scans of 1297 belonging to 782 adults over age 18 were obtained from archive a dental clinic. Within this dataset, 129 had undergone endodontic treatment and po...

BACKGROUND Dental caries among children is one of the greatest challenges faced by dentists globally; especially that of susceptible surfaces like the Pit and fissures. Dental sealants have proved to be an effective way to prevent caries development. The Clinical success of any material depends upon its adhesion to tooth structure, resistance to wear and ability to withstand the masticatory or ...
