Dentigerous Cyst associated with Impacted Maxillary Premolar: A Rare Site Occurrence and a Rare Coincidence.

A dentigerous cyst is a developmental odontogenic cyst occurring most commonly in the third molar region of mandible and maxilla and maxillary canine region followed by mandibular premolar areas. However, dentigerous cyst occurring in association with impacted maxillary premolars is a very rare presentation accounting for less than 0.5% of total dentigerous cyst cases. In the following case report, a dentigerous cyst was reported in maxillary premolar region in a nonsyndromic patient having one missing premolar and another malformed one associated with the dentigerous cyst.

Soft Tissue Applications of Er,Cr:YSGG Laser in Pediatric Dentistry.

Soft tissue laser, such as diode and Nd:YAG lasers were initially used in soft tissue lesions because of its increased success rate. It was because of the fact that these lasers were well-absorbed by chromophores, such as hemoglobin and melanin which are found abundant in the oral mucosa. The introduction of erbium family in 1990 comprising the Er:YAG and Er,Cr:YSGG lasers made the hard tissue laser a boon for dentistry. Erbium, chromium-doped yttrium, scandium, gallium and garnet (Er,Cr:YSGG) was introduced in 1997 for the surgical needs of clinical dentistry in general practice. The erbium belongs to the rare earth which is embedded in a host crystal. The actual lasing process takes place in the Er ion Er3+. Two host crystals consisting of yttrium, aluminum, and garnet (Y3A5O12) and yttrium, scandium, gallium, and garnet (Y3Sc2Ga3O12) are added to the erbium. The interest to use these hard tissue laser in the treatment of soft tissue lesion was because of the properties of these lasers which are well-absorbed by chromophore water apart from hydroxy appetite crystals. Erbium laser energy is absorbed by collagen, hydroxyapatite, and water components. It allows the laser to cut soft tissue, tooth structure, and bone. In the noncontact mode, the incision is scalpel-like, with very little hemostasis. In contact mode, it performs soft tissue sculpting with adequate hemostasis. The Er,Cr:YSGG is the world's most advanced dental laser, which is ideal all-tissue laser because all dental tissues contain water, for the multidisciplinary dentist who performs a broad spectrum of procedures. It delivers the highest level of clinician control, operating efficiency, flexibility in tip, and accessory selection. For optimal clinical results and patient comfort in hard and soft tissue procedures, the erbium lasers have set a new standard of clinical performance. The present case series aims to highlight the various soft tissue applications of Er,Cr:YSGG (Waterlase Biolase®, Biolase, Inc, San Clemente, California, USA) in pediatric patients.

Peripheral ossifying fibroma, some rare findings.

The peripheral ossifying fibroma (POF) is a benign reactive gingival overgrowth; it occurs mainly in the anterior portion of maxilla in young adults, predominantly among females. The present report describes a case of POF in a male patient, which relapsed ten years later and of the lesion showed superficial bone erosion on surgical excision.

Regenerative therapy as an adjunct to periapical surgery: a case report.

Large periapical defects may adversely affect the success rate of endodontic surgery. Use of regenerative therapy may enhance the prognosis of such teeth. A case of traumatized upper anterior teeth with infected radicular cyst and associated sinus tract reported to the dental hospital. A periradicular surgical procedure was performed to remove the nonhealing pathological tissue. To augment the repair a bioactive bone graft material was placed. Six months interim results showed positive outcome of application of graft. How to cite this article: Chaturvedy V, Chaturvedy S.
