The aim of this retrospective radiological study was to evaluate the variability of the mandibular anatomy in the presence and absence of teeth and to consider how it could influence implant planning. 187 mandibular CT DentaScans were selected from our department archive according to the inclusion criteria. The axial height, vertical height, angulation of the bone crest, and the bone available ...

Gingival fibromatosis (GF) is a heterogenous group of disorders characterized by progressive enlargement of the gingiva caused by an increase in submucosal connective tissue elements. This article presents a case report of a 14-year-old female patient with idiopathic gingival fibromatosis in the maxillary region with radiographic feature of congenitally missing maxillary permanent left lateral ...

The present study reports the treatment carried out in a patient with mandibular second premolar agenesis associated with early loss of a deciduous second molar, deep overbite, severe overjet and dentoalveolar bimaxillary protrusion, which led to lip incompetence and a convex facial profile. The main objectives of this treatment were: to eliminate the spaces in mandibular arch, correct overbite...

Pretreatment, end of treatment, IO-year postretention, and 20-year postretention records of 31 four premolar extraction cases were assessed to evaluate stability and relapse of mandibular anterior alignment. Crowding continued to increase during the loto 20-year postretention phase but to a lesser degree than from the end of retention to 10 years postretention. Only 10% of the cases were judged...

The aims of this study were to compare the maximum range of protrusion determined with a ruler with measurements made using a George Gauge (GG) and to validate the methods of measurement (ruler and GG) of the advancement established by mandibular protruding devices (MPDs), using cephalograms as the gold standard. The study comprised 77 patients (63 males, 14 females, mean age 54 years, range 31...

Bitewing radiographs have been one of the dentist’s chief diagnostic tools in the dental clinic. They increase detection of interproximal caries approximately two-fold when compared to clinical examination alone. To a much lesser extent, the bitewing may be used to diagnose occlusal caries. The dentist examining a bitewing radiograph will pay attention to the alveolar crests thus assessing peri...

Mandibular premolars usually have a single root and canal. Complex root canal system with atypical variations is a common finding among them. Failure to identify such a one can affect the prognosis of endodontic treatment. Apart from knowledge and sophisticated instruments, a good clinical expertise is required in identifying, tracing and treating such a root canal system. This case report is o...

Successful endodontic treatment depends on thorough knowledge in root canal morphology, appropriate assessment of pulp chamber floor, critical interpretation of radiograph, and on biomechanical preparation followed by three dimensional obturation of root canal system. The possibility of additional root /canal should be considered even in teeth a low frequency of abnormal root canal anatomy. Man...

A 17-year-old female presented with the chief complaint of inability to bite properly. Clinical examination revealed a Class II, division 1 malocclusion with an anterior open bite and mild maxillary and mandibular tooth-sizearch-length discrepancies (Fig. 1, Table 1). The patient’s initial contact upon closure was between the maxillary and mandibular first molars, leading to a complex open bite...

OBJECTIVE The purpose of this study was to determine the root canal anatomy of mandibular first premolar teeth in an Emirati subpopulation using a decalcification and clearing method. MATERIALS AND METHODS One hundred permanent mandibular first premolar teeth extracted for orthodontic purposes from an Emirati subpopulation from the United Arab Emirates were used for this study. They were subj...
