Dentigerous cyst is the most common odontogenic cyst. It is characterized by a unilocular radiolucent lesion that encloses permanent tooth buds or, under certain circumstances, displaced tooth buds. Buccal bony expansion and a missing tooth is the most common clinical feature. Various treatment modalities have been mentioned in the literature for management of dentigerous cysts. This article presents a left mandibular dentigerous cyst in a 10-year-old boy. Marsupialization was the treatment of choice and a denturelike space maintainer was provided. Long-term follow-up revealed good healing of the bony lesion.How to cite this articleBhardwaj B, Sharma S, Chitlangia P, Agarwal P, Bhamboo A, Rastogi K.

“…In addition, odontogenic cysts in tooth roots are derived from the epithelium associated with the development of the dental apparatus. The three principal types are radicular, dentigerous, and keratocysts, and are distinguished by their morphogenesis (4).…”

A Spontaneous Mutation: Amelogenesis Imperfecta with Cysts in Rats

et al. 2003

Amelogenesis imperfecta (AI) is an inherited dental disease of enamel formation in humans, and there are various phenotypes due to the combination of enamel quality and quantity. We encountered four female IGS rats with spontaneous AI including odontogenic cysts in the incisor teeth. Histopathologically, in the incisors of the rats, the enamel organ was disorganized with the remaining enamel matrix residing within the enamel space. The expanding cysts derived from the enamel organ were formed in the periosteal connective tissue on the labial side. At the bottom of the tooth germs, the precursor cells of the epithelial root sheath were arranged regularly and the enamel organs were preserved to the same degree as those of normal rats. In the molar teeth of the affected rats an enamel matrix remained on the neck and crown of the erupted teeth; however, no abnormality was observed at the tooth root. Although an animal model of AI has been developed from mutants of the SHR-SP rat strain, the present cases represent another potential model of the disease because of the differences in the way the enamel matured and the odontogenic cyst formation in the incisors.

With the specific aim of the examination of tissue-damage and repair of surgically exposed pulp and periapical region in rat molar model, 14 female Sprague-Dawley rats were used. The coronal portion of lower first molars was surgically removed and the teeth remained untreated for 3 weeks prior to euthanasia of the animals.During this experimental period, all animals were injected with fluorochrome agents twice at the 12th and 19th days, in order to monitor formation of hard tissues in the exposed pulpal chamber and on the surfaces of cementum and alveolar bone. For histologic examination using microradiography and fluorescent and light microscopy, resin-embedded ground sections and serial decalcified sections were prepared. Observations revealed that: (1) over half of the surgically treated teeth gave rise to the formation of osteodentin so that the exposed pulp was partially covered; (2) the number of root canals filled with necrotic tissues was less than 25% of the total teeth examined, while the majority comprised vital granulation tissues and newly formed osteodentin, in certain cases with the appearance of odontoblastic cells aligning on the dentin wall; and (3) active deposition of cementum on the root apex and remodeling of alveolar bone were prominent in most of the treated teeth. The overall results support the contention that rat molar pulp has high potential activities for tissue-repair including hard tissue formation after pulpal exposure to the oral enviroment.
