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...

This report describes the nonsurgical treatment of a patient with skeletal Class II protrusion and severe crowding. A 20-year-old woman presented with the chief complaint of lip protrusion and crowding. To correct the Class II relationship, severe crowding, and lip protrusion, distal movement of the maxillary first molars using indirect miniscrew anchorage and nickel-titanium coil springs, alon...

The maxillary first premolar may present large number of anatomic variations. The clinician should be aware of the configuration of the pulp system. Maxillary first premolars usually have two canals. The incidence of three canals in these teeth is quite rare. This case report presents the diagnosis and clinical management of a maxillary first premolar with two distinct canals in the apical thir...

In our orthodontic practice we have seen a recent spurt of increasing numbers of young adults who desire cost effective, non surgical correction of Class II malocclusion and accept dental camouflage as a treatment option to mask the skeletal discrepancy. When planning the treatment in such cases the orthodontist often faces the dilemma whether to extract 2 maxillary premolars or 2 maxillary and...

OBJECTIVE To determine the internal root morphology of the maxillary first premolar in Kenyans of African descent. DESIGN In vitro descriptive cross-sectional study. SETTING School of Dental Sciences, University of Nairobi. SUBJECTS One hundred and fifty five extracted maxillary first premolars obtained from patients aged between 13-30 years attending dental clinics within Nairobi. RESU...

Bi-maxillary protrusion is a condition with protrusive and proclined upper lower incisors the patient not able to close lips without strain. The presented case reported chief complaint of forwardly placed teeth, skeletal class II malocclusion, Angle’s I malocclusion incisors. treatment was performed extraction all first premolars retraction under absolute anchorage. about 3 mm 3.5 achieved resp...

PURPOSE The objective of this study was to assess the pattern of permanent teeth present in a self-selected sample of 17 female and 35 male patients with ectodermal dysplasia presenting for treatment with dental implants. METHODS Mean age of sample: 18.7 years, age range: 5.9 to 60.9 years. Panoramic radiographs were examined independently by two investigators to determine the permanent teeth...
