Failure of eruption of primary teeth can be considered rare, especially in maxillary anterior teeth. The problem can be either mechanical obstruction of eruption or a failure of the eruption mechanism. This case report presents failure of eruption of the maxillary right deciduous central incisor in a 4-year-old girl. The unerupted primary tooth was removed surgically. The histological finding r...

The occurrence of supernumerary teeth is a relatively uncommon dental anomaly and it's rare for patients to have impacted fourth molars in all quadrant. Aim of this work is to describe the presence of bilateral fourth molars in the maxilla and the mandible in a young male patient aged 22 years came to our hospital with acute pericoronal infection around unerupted third inferior molars. Routine ...

The authors report a case of the traumatic bone cyst in left mandibular body 17-year-old girl. lesion was diagnosed radiographically as an accidental finding. radiographic characteristics unusual showing image involving unerupted third molar.

Intermittent tongue, lip and cheek forces influence precise tooth position, so we here examine the possibility that tissue remodelling driven by functional bite-force-induced jaw-strain accounts for tooth eruption. Notably, although a separate true 'eruptive force' is widely assumed, there is little direct evidence for such a force. We constructed a three dimensional finite element model from a...

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...

"Occult" or "hidden" caries refers to occlusal caries which is not diagnosed clinically because the occlusal surface appears ostensibly intact, and radiographs show radiolucencies in dentin. The prevalence of occult caries has been reported to range from 2.2% to over 50% of permanent molars. In spite of its relatively high prevalence, the etiology and pathogenesis of occult caries remain unclea...

The invasion of the mandible by oral squamous cell carcinoma has been firmly demonstrated by anatomical and histological studies. Although squamous cell carcinomas may induce resorption of the roots of standing teeth, there have been no reports of them also causing resorption of the crowns of teeth. A 73year-old patient presented with an invading buccal squamous cell carcinoma. Radiological inv...

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...

The eruption of the second molars may delay therapy and lengthen treatment time. To minimize excessive prolongation, principle resistance factor elimination was applied to unerupted lower molar through a surgical incision on occlusal gingival tissue. 3.7 successfully erupted easily bonded following month, allow archwires sequence.
