Dental anomalies are the formative defects caused by genetic disturbances or environmental factors during tooth morphogenesis. Simultaneous occurrence of various multiple anomalies has been reported previously, particularly in cases of chromosomal abnormalities that often manifest with multisystem involvement. Very few cases of multiple anomalies have been documented in patients with no known g...

This study reviews rim excision as a treatment for canine acanthomatous ameloblastomas (CAA) in dogs with <3 mm of bone involvement. Removal of a canine tooth was involved in 47% of the cases; 33% cases involved the caudal dentition. Follow-up ranged from 3 months to 5 years. No evidence of recurrence was seen. Client satisfaction with cosmesis and the animal's ability to masticate was judged t...

The adenomatoid odontogenic tumor (AOT) is a benign, nonneoplastic (hamartomatous) lesion with a slow progressing growth. It occurs in both intraosseous and peripheral forms. This paper reports the case of a female aged 16 years who presented with a swelling in anterior maxilla; canine was missing, and a supernumerary tooth was present in the mid line. Radiology revealed a well-defined radioluc...

Duration of treatment is one of the main concerns of patients undergoing orthodontic treatment. Fixed orthodontic treatment lasts up to 2 to 3 years increasing the risk of external root resorption, periodontal problems and patient compliance [1]. Clinicians are constantly striving towards developing strategies to enhance the rate of orthodontic tooth movement. An increase in in-depth knowledge ...

We report a case of apical fenestration misdiagnosed as persistent apical periodontitis. The patient was a 55-year-old woman who presented with persistent tooth pain at the right maxillary canine, despite repeated root canal treatment by a general practitioner. When the patient visited Tokyo Dental College Suidobashi Hospital, a CT examination was performed and apical fenestration diagnosed. Th...

This study examined the effect of critical appraisal exercises on the quality of preclinical tooth preparation skills and the confidence level of undergraduate dental students at a dental college in India. Forty-two student volunteers were randomly divided into critical appraisal (CA; n=19) and control (C; n=23) groups. Both groups were given conventional lecture and video demonstration; the CA...

OBJECTIVES This study investigates coincidence of the most-prominent point and the mid-point on upper anterior teeth in relation to the use of straight-wire appliances. MATERIALS AND METHODS Alginate impressions of the upper jaw were obtained from forty Caucasian patients. Impressions were cast using hard dental stone. The teeth on each upper study model (canine to canine) were marked along t...

Congenital morphological dental alterations are related to the physiological phase of tooth development. Since the etiology of the dens invaginatus and supernumerary roots has yet to be fully determined, a rare presentation of dens invaginatus in a primary molar and a birooted deciduous maxillary canine were incidentally detected in routine radiographic examinations. Essential clinical consider...

conclusions based on the clinical and radiographic examinations, implant-tooth approximation (less than 1 mm or direct contact) is not related to pulp vitality of the tooth. further studies with larger sample sizes are necessary to confirm the results of the study. results among the 31 assessed implants and the adjacent intact teeth, 13 implants had direct contact and 18 implants had proximity ...

Mandibular canines are single rooted tooth with one root canal in general. Various literature reports that approximately 15% may have two canals or sometimes two roots. This paper reports a clinical case of mandibular canine with two roots and two canals.
