Role of Ultrasonography in Oral Submucous Fibrosis

2018-11-24T17:26:48+00:00

Sonography was introduced in the medical field in early 1950's but it took few years for it to get entry in to dentistry.Recently some studies have shown that ultrasonography can be used as non- invasive imaging modality to assess the extent and severity of the fibrosis and vascularity across the mucous membrane.This review emphasizes the role of ultrasonography in diagnosing and predicting the prognosis of Oral Submucous fibrosis.

Brachytherapy – Principles and Practice

2018-11-30T17:26:19+00:00

Radiation Therapy is one of the potent treatment modality in treating various cancers importantly oral cancers. Cells in Oral Cancers are sensitive to radiation which dictates exploration of various modalities of radiation therapy. Brachytherapy is one such modality which has a proven history of efficacy and future that needs exploration. This review details the past, present and future of Brachytherapy.

A Comparison of Various Current Electronic Apex Locators to Determine the Working Length by Using the Clearing Technique

2018-11-16T17:16:58+00:00

Background: To evaluate the accuracy of Dentaport ZX, Woodpex Electronic Apex Locators in establishing the major foramen using clearing technique

Methods: Thirty Maxillary and Mandibular human extracted teeth with a single root straight canal were used and decoronation were done up to CEJ with a diamond disc, 15 samples of teeth from each group were embedded in a dentulous model and alginate was placed in it to stimulate periodontium . Working length estimation was done by “Woodpex, Dentaport ZX Electronic Apex Locators” – models placed in 5% Nitric acid for 24,48 and 72 hours, then transferred to ethanol solution of concentration(80,90,100%) and stored in 0.2% Methyl salicylate. Distance between tip of file and major foramen was measured by using image analysis and values were listed to statistical analysis. Statistical analysis was carried out by using tests of chi square test, kruskal wallis test, Z test to compare results between two groups. All the data was expressed as Mean ± SD and the difference of p≤ 0.05. Values obtained were analyzed by using image analysis software program

Result: Accuracy were 100% for the Denta port ZX compared to Wood pex in detecting major foramen

Conclusion: Accuracy of Dentaport ZX was higher compared to wood pex. Dentaport ZX located the major foramen with 100% accuracy within the range of 0.5mm.There is greater distance from the major foramen in woodpex group when compared to dentaport ZX.

Clinical and Histopathological Spectrum of Salivary Gland Lesions in A Tertiary Center

2018-11-16T17:26:27+00:00

Background: The objective of this study was to determine the clinical pattern and histopathological features of salivary gland lesions (SGL) in patients presenting to a tertiary hospital in Southwest Saudi Arabia.

Methods: A retrospective study was conducted in histopathology section of Department of Laboratory Medicine from January 2014 to February 2018 on tissue specimens from salivary gland lesions. The histopathological diagnosis was made according to World health organization classification (2017) based on light microscopy followed by special stains and immunohistochemistry wherever necessary.

Results: A total of 70 specimens were received in hospital during this period. These comprised of 8 inflammatory lesions and 62 tumors. Salivary gland tumors involved 29 males and 33 females, male: female ratio= 0.8:1 with mean age of 44.5 years. 46 (74.2%) were benign and 16 (25.8 %) were malignant. Parotid gland was involved in 47, submandibular gland in 4, sublingual gland in 3 and minor salivary glands in 8 cases.

Conclusions: Our study revealed that tumors are the commonest lesions in specimens of salivary gland masses with pleomorphic adenomas being the predominant tumor (51.6%) . Parotid was the most commonly involved gland with majority of the tumors being benign (82.9%). Submandibular gland was involved by benign lesions in 87.5 % cases out of which 50 % were inflammatory in nature . Sublingual and minor salivary glands were predominantly affected by malignant tumors constituting 70 % of cases.

Dentigerous Cyst with Cholesterol Clefts in the Mandible: A Rare Case Report

2018-11-16T17:32:53+00:00

Dentigerous cysts; are benign odontogenic cysts associated with crowns of impacted teeth. Cholestrol clefts are the microscopic cavities formed in these regions, which result in the formation of cholesterol crystals that accumulate in tissues. In this case, we present the enucleation and treatment of infected dentigerous cyst and the cholesterol clefts found in large volumes. A 58-year-old man with type 2 diabetes admitted to our clinic for routine check-ups. Radiologically, large radiolucency was observed around the number of impacted third tooth. Under general anesthesia, the lesion and associated lesion-related tooth were removed and sent for histopathological examination. Histopathological examination revealed a final diagnosis of infected dentigerous cyst and cholestrol cleft within the cyst lumen. Cholesterol cleft is an inflammatory reaction to cholesterol crystals deposition. Very few cases of cholesterol cleft occurring in the dentigerous cyst of the jaws were reported. Dentigerous cysts can reach large sizes without any finding. Therefore, the areas where the teeth are extracted or unerupted should be examined clinically and radiographically cautiously, in this way possible lesions should be treated before reaching big sizes.

Root-End Closure of Pulpally Involved Anterior Teeth Using Metapex: A Case Series

2018-11-16T17:35:57+00:00

Management of pulpally involved teeth with immature apices is a difficult task for the clinicians. Despite major advances in biomaterials and technologies, successful closure of root apex depends upon the accurate diagnosis and treatment planning. Apexification is defined as “a method to induce a calcific barrier in a root having an open apex or the continued root development of an incomplete root in teeth with necrotic pulp”. The present paper represents a case series of management of pulpally involved teeth with immature apices using Metapex (MetaBiomed Co., Ltd, Korea) as an apexification agent. In all the above cases successful closure of immature apices occurred though closure timings were different for all the cases.
