Changes in the permanent upper central incisors (Hutchinsonian teeth) and in the permanent first molars (Moon, 1877, 1884; Pfluger, 1924) are two of the most important stigmata of late congenital syphilis. These stigmata are not seen until the second dentition, in the incisors after about 7 years of age and in the molars after the 6th year. In radiographs however, Stokes and Gardner (1923) demo...

A longitudinal complicated crown-root fracture of an unerupted permanent incisor following trauma to primary teeth is reported. The development of the affected permanent tooth was not disturbed during a follow-up period of six years. Traumatic injuries to primary teeth can be transmitted to the permanent dentition because of the close relationship between the apices of primary teeth and the dev...

Paradentalcyst(PC) is an “inflammatory cyst arising on the lateral aspect of a vital tooth as a result of an inflammatory process in the periodontal pocket”. Its prevalence varies from 1 to 5% in all odontogeniccysts,which accounts for its inclusion in the group of rare lesions. The most common site being distal &buccal aspect of partially or fully erupted mandibular 3rd molars, the present pap...

UNLABELLED Dentigerous cysts, also known as follicular cysts, are a relatively common pathology in our field. They are associated with unerupted or semi-erupted teeth and are usually not related to supernumerary teeth. OBJECTIVE To describe a dentigerous cyst case associated to a supernumerary tooth. CASE-REPORT A large-sized dentigerous cyst is described, associated with a supernumerary to...

BACKGROUND Many reports have indicated the treatment for permanent teeth with disturbed eruption due to the presence of supernumerary teeth. However, successful treatment for an unerupted maxillary incisor with severe rotation and another maxillary incisor with disturbed eruption by a supernumerary tooth is quite rare. CASE REPORT We treated a 7-year-old Japanese male with an unerupted and se...

OBJECTIVES Proper diagnosis and prevention of malocclusion are superior to treatment. Discrepancy between arch length and tooth size in mixed dentition period is a condition requiring timely diagnosis. Estimating the mesiodistal width of unerupted teeth according to the size of erupted ones can lead to earlier diagnosis of malocclusion. On the other hand, the best timing for serial extractions ...
