Dental caries and the severity (depth) and area of erosions of tooth substance were studied in 11 bulimic subjects and 22 matched controls. Erosions were seen in 69% of the bulimics' teeth and in only 7% of the controls' (p less than 0.001). Depth of penetration was greater in the bulimics, extending even into the pulp, and the area of erosion was also larger. Scores for dental caries were high...

Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. The cause of dens invaginatus is still unknown and controversial. Some hypotheses suggested by authors are: local external forces, apical proliferation of ameloblast or local retardation, arresting of development and focal developmental stimuli. Th...

Maxillary dentigerous cysts although uncommon need to be considered in the differential diagnosis in children with painless facial swelling. We present a case of dentigerous cyst associated with maxillary deciduous canine and maxillary premolars manifesting as a unilateral swelling in canine region of the face. A ten-year-old boy came to oral and maxillofacial surgery unit with a painless left ...

This clinical report describes an interdisciplinary (oral surgery, orthodontics, and prosthodontics) approach for the coordinated treatment of a patient diagnosed with operated cleft palate and lip. On intra oral examination gingival cleft, missing maxillary left central and lateral incisors and maxillary right premolars and orthodontic malocclusion were present. The patients' specific esthetic...

This case illustrates orthopaedic treatment of a 12.1-year-old girl with class III malocclusion and maxillary deficiency. The patient was treated by a fixed tongue appliance in the upper jaw. First maxillary molars and premolars were banded and a hyrax was mounted on them in order to achieve lateral expansion. A fixed tongue appliance comprising of a few cribs was soldered to the anterior side ...

ment can be particularly challenging in adult patients. Although many appliances have been proposed for maxillary molar distalization in such cases,1,2 they generally require some degree of patient compliance, and their de sign causes anchorage loss due to the incorporation of occlusal rests or bands on the premolars. The introduction of skeletal anchorage has radically changed orthodontists’ a...

It is very important that the dentists have sufficient information about possible variations in the expected root canal configurations in order to achieve success in endodontic treatment. In addition to having adequate knowledge on the variations of the root canal anatomy, periapical radiographs from different angles, careful examination of the pulp chamber floor, and use of dental operation mi...

The hypodontia of a permanent tooth from a dental group represents a normal evolution in human dentition morphology. Nevertheless, the hypodontia of two teeth within a dental group is a rare developmental anomaly when not associated to a systemic syndrome. The aim of this study was to report two rare cases of four maxillary premolars hypodontia, not including the third molar, of two white women...

OBJECTIVE To compare single buccal articaine injection versus conventional lignocaine buccal and palatal injections for uncomplicated maxillary tooth extractions. STUDY DESIGN Single blinded randomized control trial. PLACE AND DURATION OF STUDY The outpatient department of Oral and Maxillofacial Surgery, Armed Forces Institute of Dentistry, Rawalpindi, from February to September 2011. MET...

To perform successful endodontic therapy, it is important to know the anatomy and morphology of the root canal system. Peculiarities with possible anatomic variations may lead to failure due to insufficient instrumentation and inadequate three-dimensional obturation of the root canal system.[1,2] Accurate radiographic examination using different horizontal angles is crucial for the endodontist ...
