The aim of the present study was to evaluate the need to distinguish between white and black patients when predicting the combined mesiodistal crown width of canines and premolars in Recife. A sample of 120 dental casts (60 from black and 60 from white patients) was selected from the archives of dental clinics in Recife. The mesiodistal crown width of the maxillary and mandibular canines and pr...

background and aims . a perfect endodontic treatment necessitates proper understanding of the morphology of canal and pulpal variations. this in vitro study was conducted to demonstrate the internal anatomy of mandibular canine teeth in an iranian population. materials and methods . the samples consisted of 100 extracted mandibular permanent canines. the roots of the teeth were molded in acryli...

The maxillary permanent canine acts as the corner stone of occlusion and plays a key role in smile design. Any morphological defect or eruption anomaly, affecting the maxillary permanent canine has a negative impact on the smile and facial esthetics of the person. The etiology of impacted maxillary permanent canine is multifactorial. Maxillary transverse discrepancies have been reported in 7 – ...

Background: The radiographic method for deter­mining the estimated age has advantage of being non-invasive and orthopantomogram images are digitally processed. Canines have a strong corre­la­tion with chronological good resistance large pulp space. This study aimed to determine difference in estimates using Kvaal on right left mandibular canines. Subjects Method: There were 80 ortho­pantomogram...

Anatomical variation in the number of roots and root canals can occur in any tooth. Aberrant morphology of the root canal system may hinder cleaning and shaping procedures, leading to failure of endodontic treatment. The aim of this paper is to show one an example of root canal anatomical variation. Mandibular canines usually have one root with a centrally located root canal; however, anatomica...

This study aimed to evaluate oral health-related quality of life (OHRQoL) in partially dentate subjects, presenting extreme tooth loss in posterior region with missing post-canines, comparing the use of conventional removable partial dentures (RPDs) and implant-supported RPDs. OHRQoL was measured using the Brazilian version of the Oral Health Impact Profile. Twelve subjects presenting maxillary...

OBJECTIVES The aims of the present study were to determine anterior and total tooth-width ratios in a representative Iranian sample in Tabriz city and compare them with the Bolton standards. STUDY DESIGN A total of 54 Iranian schoolchildren (12-14 years old) in Tabriz were examined. Alginate impressions were taken for subjects and poured by the dental stone. The mesiodistal widths of the teet...

STATEMENT OF PROBLEM When reconstructing the occlusal curvatures dentists often use a 4-inch radii arc as a rough standard based on Monson spherical theory. The use of an identical radius for the curve of Spee for all patients may not be appropriate because each patient is individually different. The validity of application of this theory in the Indian population and the present study has been ...
