A Dentigerous Cyst (DC) is the most common developmental odontogenic cyst that mostly happens in patients between 10 to 30 years of age. It is usually completely asymptomatic and is discovered on a routine radiographic examination or to evaluate the reason for an erupted tooth. Radiographically, this cyst usually presents a well-defined unilocular radiolucency attached to CEJ of an unerupted to...

External root resorption may occur as a consequence of trauma, orthodontic treatment, bacterial infection or incomplete sealing of the root canal system (bacterial re-infection), and lead to crater formation on the resorbed apex. This would deform the root apex surface, and cause loss of apical constriction. Depending on the extent of the resorptive process, different treatment regimens have be...

The optimal treatment for intruded permanent teeth has not yet been determined. The ideal treatment option is the one with the lowest probability of developing complications such as external root resorption and marginal bone loss. Each case should be considered individually, bearing in mind the severity of the intrusion, the stage of root development, and tooth mobility. Management of an intrud...

Background: Bone resorption due to tooth extraction leads unpredictable bone volume for future prosthetics. Crab shells were promoted as a solution prevent resorption, along with an effort reduce biological waste. Purpose: This study aimed analyze the expression of sialoprotein (BSP) and dentine matrix protein-1 (DMP1) in wound healing process tooth-extraction sockets after applying crab shell-...

Mineral trioxide aggregate (MTA) has shown potential as a repair material for perforations. This clinical case demonstrates that when MTA was used as a repair material for root perforation due to invasive cervical resorption, the tooth was well in function for 27 months. Both clinical and radiographic follow-up showed a stable condition without any probing defect, ongoing root resorption, or ap...

Invasive cervical root resorption frequently results in the loss of the affected tooth, which can come at a considerable functional and aesthetic cost to the patient. Many of these cases are now treated with implant replacement which involves further surgical and financial costs. Numerous papers reporting on cervical root resorption have looked at the possible aetiology of Multiple Idiopathic C...

Introduction: Inflammatory external root resorption in the permanent dentition is a dental complication, usually associated with inflammation of bacterial/endodontal origin. This case report describes nonsurgical root canal retreatment of a mandibular molar with inflammatory external root resorption (IERR) and open apex with calcium enriched mixture (CEM) cement. Case Report: Radiographically, ...

Root resorption (RR) is the loss of dental hard tissues as a result of clastic activities. Internal inflammatory root resorption (IRR) is a type of RR characterized by progressive loss of tooth substance starting from the root canal wall. IRR is usually asymptomatic, slowly progressing, and detectable upon routine radiographic examination or by the clinical sign of a ‘pink spot’ when the IRR in...

Since ideally effective tooth movement in orthodontics should occur without causing damage to the periodontal ligament (PDL), a new bracket with a ratchet-locking system, the 'Ratchet Bracket', was designed to produce tooth movement while maintaining blood circulation. To define the mechanism of the appliance, a histological study was carried out on four Beagle dogs (9 months old) and a clinica...

Pulp samples of 50 healthy human teeth with indication for extraction were examined to evaluate the role of apoptosis in pulp elimination during physiological root resorption. Two groups were formed: a test group (n=30) composed of pulp samples of primary teeth with physiological root resorption and a control group (n=20) composed of pulp samples of permanent maxillary third molars. Morphologic...
