A RETROSPECTIVE EVALUATION OF OROFACIAL AIRWAY DIMENSIONS AFTER RAPID MAXILLARY EXPANSION
Author Name: P J Antony, Joby Paulose , Eldho Markose, Eldho T. Paul
Abstract: Objective: The purpose of the study was to assess the sagittal oro-pharyngeal airway dimensions after rapid maxillary expansion in Indian populations.
Materials and methods: Pre and posttreatment lateral cephalograms of 100patients treated with rapid maxillary expander were obtained. Cephalo metricvalues (pre and post expansion) of upper and lower air way spaces in sagittal dimension were recorded and compared.
Results: There was a significant increase in the sagittal dimension of the upper airway. However, no substantial difference was observed with respect to the sagittal dimension of lower airway.
Conclusion: Rapid maxillary expansion definitely improves the upper pharyngeal airway, but has limited influence on the lower pharyngeal airway.
Keywords: Rapid Maxillary expansion, oropharyngeal airway dimensions, lateral cephalograms
AUTOFLUORESCENCE SPECTROSCOPIC STUDY OF ORAL SQUAMOUS CELL CARCINOMA
Author Name: Murali CR , Saraswathi TR
Abstract: Background: The success of treatment of all forms of carcinoma to a great extend is influenced by the time interval between the genesis of the lesions, its diagnosis and adequate treatment. In spite of the better access to oral cavity majority of the malignancies are diagnosed at a late stage. In this context a noninvasive diagnostic technique is essential to diagnose at an early stage.
Objective: To analyse the differences in the fluorescence spectral characteristics of normal, clinically diagnosed benign, inflammatory and malignant lesions of the oral cavity. Comparing the spectroscopic ratios with the histological diagnosis and assessing its use as a non invasive diagnostic procedure.
Materials and Methods: Twenty patients having Oral cancer and five patients having inflammatory and benign gingival lesions formed the study group. Five apparently normal persons formed the control groups. The control group was selected from patients who came for other dental problems. The biopsy specimen obtained was divided into two parts ,one part was send for routine histopathological examination and other one was send for in vitro auto fluorescence spectroscopic study.
RESULTS: The averaged emission and excitation spectrum of oral squamous cell carcinoma was compared to normal mucosa at405nm and 420nm excitation. Based on the results two discriminating parameters DP1 and DP2 were introduced. DP1 >100 indicates normal tissues and DP1 < 100 indicates cancerous tissues. The results were plotted in a graph and a significant difference was found between normal and malignant tissues.
Conclusion: Fluorescence spectroscopy can be effectively used for diagnosing individuals affected with oral squamous cell carcinoma. However it is unable to differentiate the different grades of squamous cell carcinomas, as the sample size is very small

POSTS - HISTORY AND CONSIDERATIONS
Author Name: Sreegowri, Amarnath Shenoy, Romel Joseph, Prithviraj K
Abstract: The questions that arise during the restoration of a tooth are not new ones. The replacement of missing tooth structure has been practiced by various cultures for thousands of years. There are numerous references to the importance of healthy teeth in the Old Testament, much of which deals with the period antedating 1000 BC. No wonder than that man has made every effort to restore lost tooth structure. Talmud (AD 352-457) recorded the use of a supporting wire to secure the artificial tooth to the root. Later accounts by the Franks (AD 200-737)described the use of a wooden dowel placed in the root to provide an anchor for the artificial crown.

Author Name: Mayeesh Radhakrishna, Aiswarya CJ, Jassim KA
Abstract: premalignant condition, affecting the people of South East Asia . T h e understanding of the exact role of etiological agents like areca nut with respect to pathogenesis will help in the management and treatment modalities of this condition. This article provides an overview of the etiopathogenesis with emphasis on the recent concepts related to this chronic Premalignant Condition.

SECTIONAL COMPLETE DENTURES WITH DOWEL PINS FOR PROSTHETIC MANAGEMENT OF A MICROSTOMIA PATIENT
Author Name: Murali Karthik R, Sharmila Hussain , Padma Ariga , Anand
Abstract: This report describes a technique for fabrication of a Sectional complete denture for a patient with microstomia. The primary impressions were made by a tray less technique. Secondary impressions were made using a sectional special tray, and the final mandibular denture was fabricated by incorporating dowel pins which was easily inserted by the patient, ease in maintenance and low cost. This report describes a prosthetic treatment for a patient with microstomia.

“IT'S A NUMBER GAME”: ENDODONTIC THERAPY OF MAXILLARY FIRST MOLAR WITH SIX CANALS A CASE REPORT
Author Name: Navneet Kukreja, Abhishek Bansal, Devendra Chaudhary, Urvashi Kukreja, Jyothi Bansal, Narendra Kumar Gupta
Abstract: The aim of this article is to discuss the endodontic management of a maxillary first molar with six root canals and to emphasize the importance of having a thorough knowledge about the root canal anatomy. Nonsurgical endodontic therapy of a right maxillary first molar with three roots and six root canals was successfully performed. The canal morphology was diagnosed using a dental operating microscope and multiple angled IOPA. After good access preparations dental operating microscopes are excellent auxiliary clinical tool to locate the extra root canals.

BONE IS BOON: WHY NOT TO PRESERVE IT? ‒ A CASE REPORT
Author Name: Gupta NK, Devendra Chaudhary, Ravi Dwivedi, Amit Tandan, Manoj Upadhyay, Saurabh Uppal
Abstract: Various studies have mentioned that removal of all remaining natural teeth and the wearing of conventional complete dentures for a long time1, 2 generally results in alveolar bone loss . The major loss of alveolar bone results in compromised retention, stability and support for conventional complete denture. Therefore it is recommended to save the existing bone for successful present prostheses and in future. Conventional complete dentures have varying degree of success rate in terms of retention, stability and chewing efficiency. All these parameters are very much related to the quality and quantity of underlying bone, which is ultimate foundation for complete dentures. Root supported overdentures have been proven successful in the treatment of edentulism due to improved retention, stability and proprioceptive sensation. Several techniques have been described for the successful restoration of the edentulous mandible: this procedure is simple and uses relatively inexpensive equipment and material. The attachments incorporated in overdentures provide retention, minimizing possible movement along the path of insertion. This type of prosthesis is successful in patients with advanced ridge resorption, providing an excellent result at a reduced cost along with preservation of residual alveolar ridge.

FIBRE POSTS QUINT ESSENTIAL IN RESTORATIVE DENTISTRY ‒ A CASE SERIES
Author Name: Cindhuri IK, Anand Sherwood I
Abstract: Restoration of extensively damaged tooth is an important clinical procedure. The advent of post and core technique tobroken down tooth has produced predictable results. Currently available fibre posts feature best characteristics resulting in rehabilitation of an extensively damaged tooth. The final decision should be made after considering the restorability of the tooth. It is imperative to determine if there is an ideal clinical situation for the fibre post systems. This case series suggests the essentiality and clinical protocol for fibre post systems

Abstract: Tumors of jaw bones are among the most uncommon of all types of neoplasms. Osteosarcoma of jawbones represents a distinct group of lesions from the conventional type commonly occurring in long bones.
