Dentigerous cysts are the most common developmental odontogenic cysts of the jaw, which usually occur in the second and third decade of life. It is most frequently associated with impacted mandibular third molar teeth and impacted canines. Bilateral/multiple dentigerous cysts are rare and typically associated with developmental syndromes. Non-syndromic dentigerous cyst occurring bilaterally or involving both arches at the same time is very rare. Here, we discuss the review of literature with a case of unusual occurrence of non-syndromic bi-maxillary dentigerous cysts in a child...

INTRODUCTION: Ibuprofen sodium dihydrate, a new formulation of ibuprofen, was introduced with the claim of faster onset of analgesia. Most of the data on this new ibuprofen formulation are drawn from studies using the oral surgery model. Because this model differs significantly from the endodontic pain model, we conducted a study comparing ibuprofen sodium dihydrate with conventional ibuprofen acid in endodontic pain patients. METHODS: This randomized, double-masked study recruited subjects experiencing moderate to severe pain from a tooth diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis (n = 41)...

The pathogenesis of odontogenic infection is polymicrobial, consisting of various facultative and strict anaerobes. The dominant isolates are strictly anaerobic gram-negative rods and gram-positive cocci. The periapical infection is the most common form of odontogenic infection. Although odontogenic infections are usually confined to the alveolar ridge vicinity, they can spread into deep fascial spaces. Cavernous sinus thrombosis, brain abscess, airway obstruction, and mediastinitis are possible complications of dental infections...

BACKGROUND: Expression of various cellular/molecular factors change during the course of tumor formation from odontogenic tissues of the tooth germ. Evaluation of these factors can help provide a better perception of the tumorigenesis and biologic behavior of odontogenic tumors (OTs). Syndecan-1 is a heparan sulfate proteoglycan which has not been extensively investigated in these lesions. The objective of the present study was to assess the immunohistochemical expression of CD138 in adenomatoid odontogenic tumor (AOT), ameloblastic fibroma (AF) and odontogenic myxoma (OM) and to compare it with ameloblastoma and keratocystic odontogenic tumor (KCOT)...

Odontogenic orbital abscess is a rare but well-documented complication of sinusitis and infections spreading from dental apical lesion. We report a case of orbital abscess with periorbital cellulitis, in a 35-year-old man with positive recent dental history of a periapical dental infection arising from the second upper left premolar spread into maxillary sinus. The patient has shown facial edema, ocular pain, ophthalmoplegia, proptosis, and initial visual symptoms. A surgical intervention to drain the abscess and a revision of the dental lesion and maxillary sinus were required...

Odontogenic myxomas are rare odontogenic tumors of jaw characterised by accumulation of mucoid ground substance with little collagen. Peripheral odontogenic myxoma (POM) is extra-osseous variant of odontogenic myxomas, occurring solely in the soft tissue covering the tooth bearing portion of jaws. POM is exceedingly rare, less than 10 cases have been published till date. A case of POM is reported here in a 27-year female which was provisionally diagnosed as pyogenic granuloma.

The glandular odontogenic cyst (GOC), though rare, has now become a well known entity. The frequency of GOC ranges from 0.012% to 1.3% of all jaw cysts and its worldwide prevalence is 0.17%. The GOC's microscopic features have been well documented, and are also included in the list of World Health Organization. We report a case of GOC presenting as a unilocular osteodestructive lesion of anterior mandible in a 28-year female. The diagnosis was made on the basis of characteristic histological findings.

Fibrous growths in the gingiva with the histopathological presence of calcifications are a common occurrence in the oral cavity. These lesions can be neoplastic in nature with either odontogenic or non odontogenic origin or they can be reactive lesions. This is a case report of an unusual presentation of peripheral ossifying fibroma , unusual because of its abnormally large size with review of literature.

INTRODUCTION: The integrity of the palatal mucosa can be lost due to congenital, pathological, and iatrogenic conditions. Various surgical techniques have been suggested for the closure of palatal defects. The aim of the current study is to present the free buccal fat pad graft as a novel technique to repair the soft-tissue defects at the palate. PATIENTS AND METHODS: During a 2-year period, the free fat tissue graft harvested from the buccal fat pad (BFP) (FBFG) and used to reconstruct five soft-tissue defects of the palate in five patients (2 women, 3 men; mean age, 34 years; range, 22-58 years)...

Vacuolar H(+) -ATPases (V-ATPases) are ubiquitous multisubunit proton pumps responsible for organellar pH maintenance. Mutations in the a3 subunit of V-ATPases cause autosomal recessive osteopetrosis; a rare disease due to impaired bone resorption. Patients with osteopetrosis also display dental anomalies, such as enamel defects; however, it is not clear whether these enamel abnormalities are a direct consequence of the a3 mutations. We investigated enamel mineralization, spatiotemporal expression of enamel matrix proteins and the a3 protein during tooth development using an osteopetrotic mouse model with a R740S point mutation in the V-ATPase a3 subunit...

INTRODUCTION: Poly(lactic-co-glycolic acid) (PLGA) has been extensively explored in the tissue engineering field with good biocompatibility and biodegradability. PLGA microspheres' injectable potency makes it highly desirable in dentin-pulp complex regeneration. Therefore, we investigated the cell adhesion, proliferation, odontogenic differentiation, and matrix mineralization of human dental pulp cells (HDPCs) on a PLGA microsphere scaffold. We hypothesized that this scaffold might be suitable for dentin-pulp complex regeneration...

Mandibular swellings may occur as a result of many benign lesions of odontogenic or non-odontogenic origin. Ameloblastomas are benign tumours of odontogenic origin, whose importance lies in its potential to grow into enormous size with resulting bone deformity, it is a slow-growing, persistent, and locally aggressive neoplasm. The unicystic ameloblastoma (UA) represents an ameloblastoma variant, presenting as a cyst clinically and radiographically, but showing typical ameloblastomatous epithelium lining histologically...

A 10 yr old intact female German shepherd dog presented with a large peripheral odontogenic fibroma and malignant melanoma on her lower jaw. The tumor was resected with a unilateral subtotal rostral hemimandibulectomy. After the mandible was removed, it was devitalized intraoperatively by freezing it in liquid nitrogen. It was subsequently reimplanted. New bone tissue formed in the gap between the frozen bone and the host bone. The regenerated bone contained osteocytes, osteoblasts, and blood vessels. The cosmetic appearance of the dog was preserved...

Tumors of the pediatric facial skeleton represent a major challenge in clinical practice because they can lead to functional impairment, facial deformation, and long-term disfigurement. Their treatment often requires a multidisciplinary approach, and radiologists play a pivotal role in the diagnosis and management of these lesions. Although rare, pediatric tumors arising in the facial bones comprise a wide spectrum of benign and malignant lesions of osteogenic, fibrogenic, hematopoietic, neurogenic, or epithelial origin...

Two cases of calcifying cystic odontogenic tumor (CCOT) of the dental follicle in an impacted third molar without clinical and radiological evidence are reported during routine histopathological examination. In both the cases left mandibular third molar was mesioangularly impacted with pericoronal radiolucency of less than 2.5 mm, which was not indicative of any pathology. As a routine protocol (which is not practiced widely) of our institution, dental follicles associated with extracted molars were sent for histopathological examination...

INTRODUCTION: Odontogenic foci can rarely cause intracranial infection. Hematogenous spread is considered to be the most important pathophysiological mechanism of intracranial infection of odontogenic origin. To investigate the oral origin of intracranial infections, oral surgeons should understand the underlying mechanisms by which oral bacteria spread to the central nervous system. However, there have been very few reports of intracranial infection resulting from odontogenic infection...
