. The eruption cyst is regarded as a soft tissue analogue of the dentigerous cyst, but is considered as a distinct clinical entity. It is defined as a cyst that lies superficial to the crown of an erupting tooth, and is lined by stratified squamous non-keratinizing epithelium. Clinically, it appears as a soft, often translucent swelling of the gingival mucosa overlying the crown of the involved...

The final shape of the molar tooth crown is thought to be regulated by the transient epithelial signaling centers in the cusp tips, the secondary enamel knots (SEKs), which are believed to disappear after initiation of the cusp growth. We investigated the developmental fate of the signaling center using the recently characterized Slit1 enamel knot marker as a lineage tracer during morphogenesis...

OBJECTIVES The aim of this study was to compare crown and soft tissue dimensions of single-tooth implant restorations following early implant placement and guided bone regeneration (GBR) with contralateral non-restored teeth. MATERIAL AND METHODS Twenty-seven patients treated by one and the same surgeon and prosthodontist to restore a single-tooth gap with a class I bone defect in the premaxi...

Q Several patients who had been receiving care at the same dental office recently transferred to our practice. Although their stories were slightly different, the results appeared to be the same. For example, 1 patient stated that she had seen a new dentist for her routine examination and cleaning, and the dentist found a cavity in her lower right molar as well as in several other teeth. After ...

this report describes a case of a 7 years old girl who suffered from complicated crown fracture of right mandibular central incisor because of a bicycle accident . for the tooth partial pulpotomy with calcium hydroxide, capping was performed in order to achieve apexogenesis and the tooth was restored with a double-seal of glass ionomer cement and composite resin. the patient was reviewed over 8...

this case report describes the treatment of two immature maxillary central incisors in a 7- year-old female patient. she suffered complicated crown fracture because of trauma, and the root formation was incomplete. white mineral trioxide aggregate (mta) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. follow-up ev...

objective: introduction of fiber-reinforced composites (frc) greatly enhanced the restoration of fractured anterior teeth. the purpose of this study was to assess the effect of fiber reinforcement on fracture resistance of incisal edge composite restorations of variable thicknesses. methods: forty extracted sound human maxillary incisors were divided into four groups of 10. incisal reduction wa...

This report describes the clinical procedures involved in the treatment of a complicated crown-root fracture in the maxillary left central incisor with a wide open apex of a 10-year-old male patient, due to fall from his own height. Post-trauma treatment comprised cervical pulpotomy and adhesive tooth fragment reattachment. After 1 year, clinical and radiograph examinations showed pulp necrosis...

Intentional replantation is in practice from past many years as a treatment option for pulpless teeth and also an effective treatment option for teeth which are difficult or impossible to treat using the conventional root canal therapy. The preservation of periodontal ligament vitality, the removal of all tissue debris and irritating substances from the root surface, establishment of a good api...

A dilated odontoma is an extremely rare developmental anomaly represented as a dilatation of the crown and root as a consequence of a deep, enamel-lined invagination and is considered a severe variant of dens invaginatus. An oval shape of the tooth lacking morphological characteristics of a crown or root implies that the invagination happened in the initial stages of morphodifferentiation. Spon...
