The aim of the present study was to examine the morphology of root canals in premolar teeth with completely formed root apices. The material consisted of 139 extracted premolar teeth, including 83 first premolars (59.7%) and 56 second premolars (40.3%). Maxillary teeth made up 64% of the material and mandibular teeth 36%. In order to measure the actual root canal length an endodontic instrument...

INTRODUCTION In this retrospective study, we compared the cephalometric effects, the dental-arch changes, and the efficiency of Class II treatment with the pendulum appliance, cervical headgear, or extraction of 2 maxillary premolars, all associated with fixed appliance therapy. METHODS The sample of 82 patients with Class II malocclusion was divided into 3 groups: group 1 patients (n = 22; t...

Hyperdontia or supernumerary teeth in both arches without any syndromic manifestation are extremely rare. Supernumerary teeth are commonly associated with Gardner's syndrome, cleft lip and palate, cleidocranial dysplasia and trichorhinopha-langeal syndrome. Five cases of non-syndromic multiple premolars of maxillary and mandibular arches in Indian patients are presented here. This case series r...

Over 40 years ago, Slagsvold and Bjercke developed a method of transplanting teeth with partly formed roots. After transplantation, root growth continues, and the teeth maintain their capacity for functional adaptation. Endodontic treatment is usually not necessary. The 3 main indications for autotransplantation of developing premolars are unevenly distributed multiple agenesis, agenesis of the...

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: knowledge about the internal anatomy of the root canal and apical foramen is a critical prerequisite for root canal therapy and is necessary for the success of endodontic treatment. this study aimed to determine the distance of apical foramen from the anatomical apex and apical constriction, evaluate the deviation of apical foramen from the anatomical apex and specify the most common...

Aim This study’s aim was to investigate the relationship between deep caries, with pulp necrosis of primary molars, and the pattern of eruption of the corresponding premolars. Methods A total of 126 children were followed up to the completion of premolar eruption over an 8-year period. Criteria for case selection included arch length adequacy and absence of abnormally large teeth. Primary molar...

Background and Aim: The aim of the present study was to determine the incidence of transmigrated maxillary and mandibular canine teeth and also of the other impacted teeth, apart from third molars, in a Turkish dental patients subpopulation. Materials and Methods: This was a retrospective study of 2900 panoramic radiographs (PRs) taken from patients who were referred to the Faculty of Dentistry...

OBJECTIVES The aim of the present study was to assess the relationship between the maxillary sinus floor and the maxillary posterior teeth root tips using dental cone-beam CT. METHODS A total of 87 right and 89 left maxillary sinus regions from 92 patients were examined using dental cone-beam CT. Images were analyzed by a specialist in oral and maxillofacial radiology. Perpendicular lines wer...
