AIM This research was conducted to study the effect of school-based caries prevention program on the crowding in the early permanent dentition. STUDY DESIGN upper and lower arch crowding was compared between 78 subjects who had received a successful caries prevention programme and 94 control subjects. MATERIALS AND METHODS A study model was taken for each of the subjects. From these models ...

The purpose of this study was to produce an estimated equation for the prediction of unerupted cuspids and bicuspids for the Saudi population. In this study, dental casts of 65 Saudi subjects (37 males and 28 females) were used. The subjects' age ranged from 18 to 25 years. The mesiodistal width of all permanent teeth was measured. The data was subjected to regression analysis. Results showed t...

Presently available methods used to predict the mesiodistal widths of unerupted canines and premolars in the mixed dentition provide an estimate for the widths of one canine and two premolars which must be either doubled for the prediction of the six tooth widths on both sides of the arch, or which must be computed separately for each side of the arch. The purpose of this study was to develop, ...

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...

INTRODUCTION Adequate tooth-size ratios are required to ensure the satisfactory outcome of orthodontic treatment. Consequently, various methods of measuring tooth-size ratios have been developed being the Bolton ratio the most commonly accepted, known and used one. This ratio depending directly on mesiodistal tooth size has been associated with different ethnic backgrounds. Some authors suggest...

  In this study two groups of dental study models were selected to evaluate the relationship between the tooth size, arch dimensions , and dental crowding. The first group consisting of 56 pairs of dental study models (28 males and 28 females) with normal occlusion ( without dental crowding) ranging in  age from 16 to 20 years, were selected among 4445 students from Kerman by multi stage rando...

BACKGROUND/AIM To assess the possibility of the eruption of the lower third molar on the basis of the measured parameters: retromolar space, mesiodistal crown width of a molar and the third molar angulation. METHODS The investigation included 104 patients both sexes (43 boys, and 61 girls), 16 to 25 years old (mean age, 18 years). It was performed using the orthopanthomographic radiographs an...

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...
