The termresidual cystis used most often for retained radicular cyst from teeth that has been removed. Residual cysts are among most common cysts of the jaws. The location of all odontogenic cysts is usually intraosseous. The peripheral (extraosseous) presentations are rare. The peripheral presentation of residual cyst has never been reported in the literature. In this article, the role of CT in diagnosing an unusual peripheral presentation of a residual cyst is discussed.

Adenoid cystic carcinomas are deceptive malignancies that show slow growth and local invasion with recurrences seen many years after diagnosis. Upto 50% of these tumors occur in the intraoral minor salivary glands usually in the hard palate. Buccal mucosal tumors are relatively rare. We determined the incidence of buccal mucosal adenoid cystic carcinoma by reviewing the number of reported cases in the literature. This is the first article to analyze the occurrence of adenoid cystic carcinomas in the buccal mucosa through a review of 41 articles. Our review revealed 178 buccal mucosal adenoid cystic carcinomas among a total of 2,280 reported cases. We present a case of adenoid cystic carcinoma occurring in the left buccal mucosa of a 45-year-old female.

Hypoglossia-hypodactyly is a rare congenital anomaly affecting the tongue and the limbs. Hall in 1971 classified it under a complex group of disorders called oromandibular limb hypogenesis syndromes. It is an extremely rare condition with around 40 cases reported in the world literature. The cause of the syndrome is unknown. Some type of intrauterine trauma is the most widely accepted etiology. The characteristic features of the syndrome are hypoglossia, limb anomalies of variable degree, and micrognathia of the mandible. This unique case report of hypoglossia-hypodactyly was observed in a patient with normal mandible. In addition, patient also had pulmonary regurgitation. His parents and other siblings were normal. Positive prenatal history of maternal hyperthermia was obtained suspecting it to be the cause of the syndrome.

Ossifying fibromas form a part of the spectrum of fibro-osseous lesions of the jaws. They are rare, benign, nonaggressive tumors that are commonly seen in head and neck region. This paper presents the case of a 40-year-old female patient presented with minimal clinical symptoms, diagnosed to be suffering from aggressive form of ossifying fibroma of maxilla involving the maxillary sinus and ethmoid sinus. This paper emphasizes the importance of computed tomography in diagnosing such unapparent aggressive tumors.

This study was undertaken to determine the effect of smoking and diabetes mellitus individually and combined on the total antioxidant capacity (TAC) of saliva in type 2 diabetes mellitus. The study consisted of four groups, one control and three study groups, each with 20 subjects. Salivary and serum samples were collected from all the groups, which were further subjected to biochemical analysis. The observations of the study were subjected to statistical analysis using SPSS software version 12. The level of salivary TAC decreases secondary to diabetes mellitus and smoking. As the duration of diabetes mellitus increases, the level of total antioxidants decreases. Correlation of salivary TAC with Russell's index had a negative correlation. Smoking has a synergistic effect on diabetes mellitus in reducing the salivary total antioxidant level. Further research should be devoted to the possible benefits of supplementation with antioxidant supplements. Saliva is considered to be a representative of serum and salivary analysis is simple and noninvasive. From the clinical standpoint, it may be reasonable to conclude that salivary TAC can be a useful marker to assess the oxidative stress, as an indicator of progression of diabetes mellitus.
