Sublingual epidermoid cyst: a case report
Of all the epidermoid cysts encountered throughout the body, only 7% occurs in the head and neck area, with the oral cavity accounting for only 1.6%. Intraorally this benign slow growing and painless entity is usually located in the submandibular, sublingual and submental region. They can cause symptoms of dysphagia and dyspnoea and have a malignant transformation potential. Surgical excision is the treatment of choice. Described here is a case of gigantic sublingual epidermoid cyst
Rhinolith
Rhinoliths are rare entities encountered in clinical practice. They are calcified masses found within the nasal cavity. Which lesions can be encountered incidentally upon a routine dental radiograph. This article reports a case of such an incidental finding of rhinolith on a dental radiograph
Optimization of sensitometric properties of blue and green light sensitive dental radiographic films employing an automatic processor
Background: Accurate film processing is of paramount importance in acquiring a good diagnostic radiograph. Radiographic films show variations in densities and contrast, with changes in processing conditions, and also film type, all of which are interdependent. Therefore, this research was conducted to recognize the effect of time and temperature variations of automatic processor on the sensitometric properties of blue and green light sensitive screen films. The study also aimed to note the effect on sensitometric properties when mismatch occurred when using between the screen and film belonging to different manufacturers. Materials and Methods: Sixty green light sensitive and 60 blue light sensitive spectrally matched screen film combinations were used in the study. However, the films and the intensifying screens employed belonged to different manufacturers. These films were exposed to five different exposure times and subsequently processed in an automatic processor, using two different protocols. Initially, at constant processing time of 2.5 min, five different processing temperatures were employed. Later, maintaining constant processing temperature of 35°C and five different processing times were engaged. Density, contrast and speed were calculated, using H and D curve. Results: Results revealed increasing density, contrast and speed values with increasing processing times and temperatures of both green and blue sensitive films. Conclusion: This investigation clearly establishes the possibility of obtaining optimal sensitometric properties, despite using intensifying screens and films of different manufacturers, if spectral match is ensured
Clinical audit in dentistry: From a concept to an initiation
Clinical audit is a quality improvement process that aims to improve patient care through a systematic review of care against explicit criteria. It is a cyclic and multidisciplinary process which involves a series of steps from planning the audit through measuring the performance to implementing and sustaining the change. Although audit contains some facets of research, it is essential to understand the difference between the two. Auditing can be done right from the record maintaining, diagnosis and treatment and postoperative evaluation and follow-up. The immense potential of clinical audit can be utilized only when open-mindedness and innovativeness are encouraged and evidence-based work culture is cultivated
A retrospective study of panoramic radiographs for zygomatic air cell defect in children
Background and Aim: The aim was to determine the prevalence of zygomatic air cell defect (ZACD) among children of Indian origin and also to determine the dominant form of ZACD.
Materials and Methods: One thousand six hundred and eighty-eight routine panoramic radiographs of subjects between 7 and 18 years, processed between January 2006 and January 2009 were screened, recorded and analyzed for ZACD.
Results: Of the 1688 panoramic radiographs examined, 768 were of males and 920 of females. The radiographs were divided into two groups, Group I comprising of subjects in the age 7-12 years and other Group II in the age range 13-18 years. ZACD was found in 50 subjects, accounting for prevalence of 2.96%. Other occurrences found were unilateral 38 cases, bilateral 12, unilocular 20 and multilocular 42 respectively.
Conclusion: This study described the prevalence and characteristics of ZACD among selected Indian children. It is essential to know and determine this variant of normal anatomy and differentiate it from pathologies
