Maxillary unicystic ameloblastoma: A review of the literature

The term unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a jaw cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth. Although the histology suggests that cystic ameloblastomas follow a biologically low-grade course, recent evidence suggests that they may often behave clinically as aggressive tumors. This is supported by the high incidence of cortical perforation, tooth resorption, increase in lesion size, bony destruction, and a high rate of recurrence after simple enucleation. Here, the authors present a case report on unicystic variant of ameloblastoma in the maxilla. An attempt has been made to emphasize that it can involve the maxillary jaw, which is rarely affected and could be more aggressive than previously thought. A literature review on the topic has been added along with the case report. It is important to remember that a proper and timely diagnosis of the character and extent of a UA (with a thorough histopathologic examination of the entire specimen) can help in the overall long-term well-being of the patient.

Silver Binding Nucleolar Organizer Regions Dots in Oral Leukoplakia with Epithelial Dysplasia and Oral Squamous Cell Carcinoma: An In Vivo Study

Silver binding nucleolar organizer regions (AgNOR) in normal oral mucosa (NOM), oral leukoplakia with epithelial dysplasia (ED), and oral squamous cell carcinoma (OSCC) were studied. The mean AgNOR count per nucleus increased from NOM to ED to OSCC. Tissue showing ED in oral leukoplakia and OSCC cases showed higher counts, wider scatter, and smaller size of AgNOR dots in the nuclei. The study seems to suggest that time method has some potential in distinguishing between NOM and oral leukoplakia with ED and OSCC. Studies of larger numbers are needed to arrive at more substantial conclusions.

An unusual case of compound odontome associated with maxillary impacted central incisor.

Odontomas are the most common type of odontogenic tumor occurring within the jaws and are frequently associated with the retained deciduous teeth interfering with the eruption of permanent teeth. Compound odontomas are usually diagnosed in the anterior portion of the jaws and resemble tooth-like structure. These are usually asymptomatic. Complex odontomas are normally diagnosed in the posterior part of the jaws and consist of a disorganized mass with no morphologic resemblance to a tooth. The present case report of a 16-year-old female is a typical case of compound odontoma in the maxillary anterior region associated with retained deciduous incisor, which also resulted in failure of eruption of the permanent maxillary right central incisor. An intraoral periapical radiograph revealed the presence of a radio-opaque tooth-like structure in the apical region of retained deciduous incisor and an impacted permanent right central incisor whose path of eruption was impeded by the structure. Treatment included the surgical removal of the lesion followed by orthodontic extrusion of the impacted incisor. Follow-up was done for one 1 year and no recurrence was seen.

A Comparative Evaluation of Efficacy of Different Obturation Techniques used in Root Canal Treatment of Anterior Teeth: An in vitro Study.

ABSTRACT Aim: This study was undertaken to evaluate the percentage of gutta-percha-filled area (PGFA) using microscopic analysis of the cross-sections in the apical third of root canals when filled either with Thermafil technique, Warm Vertical Condensation technique and Cold Lateral Condensation technique without using sealers. Materials and methods: Sixty single rooted extracted per-manent teeth were collected. After crown amputation, the teeth were randomly divided into three experimental groups of 20 specimens each. Group I–Thermafil obturation technique, group II–warm vertical condensation obturation technique and group III–cold lateral condensation obturation technique. Obturation was performed by specific techniques without using sealers. After obturation, the teeth were cross-sectioned horizontally at 2 to 3 mm from apex with the help of double sided diamond disk. Sections were digitally photographed and measured under Stereomicroscope at magnification of 50×. Using a KS 100 imaging system the area of canals and the gutta-percha was recorded, also the percentage of gutta-percha filled area (PGFA) was calculated. The observations thus ob-tained were subjected to statistical analysis using ANOVA and student ‘t’ test. Results: Maximum group difference was observed between groups I and III (3.558 ± 0.138) while minimum difference was observed between groups I and II (1.223 ± 0.137). Thus, all the between group differences were statistically significant. Conclusion: This study supports the belief that the Thermafil Obturation technique produces significantly higher percentage of gutta-percha filled area (PGFA) than the warm vertical condensation technique or cold lateral condensation technique.

A study of lip prints and its reliability as a forensic tool.

Introduction: Lip prints, like fingerprints, are unique to an individual and can be easily recorded. Therefore, we compared direct and indirect lip print patterns in males and females of different age groups, studied the inter- and intraobserver bias in recording the data, and observed any changes in the lip print patterns over a period of time, thereby, assessing the reliability of lip prints as a forensic tool. Materials and Methods: Fifty females and 50 males in the age group of 15 to 35 years were selected for the study. Lips with any deformity or scars were not included. Lip prints were registered by direct and indirect methods and transferred to a preformed registration sheet. Direct method of lip print registration was repeated after a six-month interval. All the recorded data were analyzed statistically. Results: The predominant patterns were vertical and branched. More females showed the branched pattern and males revealed an equal prevalence of vertical and reticular patterns. There was an interobserver agreement, which was 95%, and there was no change in the lip prints over time. Indirect registration of lip prints correlated with direct method prints. Conclusion: Lip prints can be used as a reliable forensic tool, considering the consistency of lip prints over time and the accurate correlation of indirect prints to direct prints.

Antifungal efficacy of herbs

Candida carriage was reported to be common in oral cancer patients, with C. albicans being the predominant species. The prevalence of diseases caused by Candida species have been found to increase in recent years. AIM The aim of our study was to find the antifungal activities at MIC of selected fifteen plant leaves extracts prepared in three different solutions (methanol and ethanol) against the opportunistic pathogen Candida albicans isolated from oral cavity infections. It may also help the clinician to treat the patient not only for the particular lesion that is present, but also to treat the infection by Candida albicans so as to reduce its potential to malignant transformation. Material n methods: Leaves extract of selected plant prepared in methanolic and eethanolic solution have been chosen for the investigation of in vitro antifungal activity which acts as expectorant and not having toxic properties on humans while for comparison or control, antifungal drugs have been taken. Results showed that Candida albicans shows most sensitivity towards the standard antibiotic cotrimoazol but very less towards other drugs like Fluconazole, minocycline, erythromycin respectively which indicated Candida albicans shows some resistance character towards drugs while the herbal extracts of Lawsonia inermis, Withania somnifer, Curcuma longa, Cymbopogon citrates and Zingiber officinale gives the best inhibitory effect and they have the potential to control growth of Candida albicans.

Counteracting Bioterrorism: A Challenge to India

Bioterrorism is a potential public health threat to India. The impact of a biological attack to our nation could be devastating. Most biological warfare agents do not produce symptoms for many hours or several days, so Indians exposed to a contagious biological warfare agent could easily spread the agent to thousands before symptoms manifest. The dental profession could potentially play a significant role in the emergency response to a major bioterrorism attack. This article provides a brief overview of the threat from biological weapons, its consequences, clinical presentation of diseases and state of preparedness in India as a response to this potentially catastrophic danger.
