evaluation of enlarged follicles with unerupted teeth is always important because some changes may occur. one of the extremely rare conditions seen in dental follicles is multiple calcifying hyperplastic dental follicle. we report a case of multiple calcifying hyperplastic dental follicle. radiographs showed that mandibular third molars had a pericoronal radiolucent zone delineated by a well-de...

Tooth whitening is one of the most conservative procedures for increasing aesthetics patients, but effect bleaching on ceramic restorations has not been extensively studied.

OBJECTIVE The aim of this longitudinal study, comprising young adults without orthodontic treatment, was to assess spontaneous changes in lower dental arch alignment and dimensions. METHODS Twenty pairs of dental casts of the lower arch, obtained at different time intervals, were compared. Dental casts obtained at T1 (mean age = 20.25) and T2 (mean age = 31.2) were compared by means of paired...

Computer image monitoring was used for evaluation of dental arch changes. A new special device captured geometrically calibrated images permitting comparison of several different dental casts. In the first part of this study 792 sets of study casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: ca...
