The purpose of this study was to comparative study of Demirjian and Cameriere methods for dental age estimation of children aged 5-13 year in DELHI-NCR region. Settings and Design: The design of this study was a retrospective study of panoramic radiographs. Randomly 40 selected digital panoramic radiographs of children, both males and females in mixed dentition period (5-13 years), taken as part of diagnostic procedure, showing all seven left permanent teeth. Results: In comparison with the present study done on 5-13 year old children both DM and CM can be used for assessing CA. When comparing the estimated DA with the CA, DM overestimated the age and CM underestimated. But the value showed CM to be more accurate than DM as CM underestimated by 0.8667 years where as DM overestimated the age by 1.767. Conclusions: Cameriere method of dental age estimation is more accurate than Demirjian method for estimating the age among dental age estimation of children aged 5-13 year in DELHI-NCR region.

Vesiculobullous lesion are group of disorders clinically manifests as formation of blisters which can either be vesicles and bulla. They pose a diagnostic challenge due to their similar or polymorphic clinical signs and symptoms and histological limitations and unpredictable progress of the lesions. Molecular biology which deals with the study of biology at molecular level provides a link between clinical and histological presentations. Pemphigus group of diseases are characterized by auto antibodies directed against desmosomal proteins. Pemphigoid group of lesions is characterized by circulating IgG autoantibodies against either BP 230 (BPAg1) and BP 180 (BPAg2) basement membrane zone proteins. Dermatitis herpetiformis is characterized by granular IgA deposits in dermal papiila whereas LINEAR IgA bullous dermatosis is characterized by IgA antibodies against 97 kDa protein (LABD 97) AND 120 kDa proteins. In epidermolysis bullosa aquisita autoantibodies are directed against type VII collagen fibres which is different from dystrophic epidermolysis bullosa characterized by mutation in type VII collagen.

Introduction: Snoring which falls within the spectrum of sleep-related breathing disorders considered to be a common symptom of airway obstruction. Over the years, lateral cephalometric radiography has become one of the standard diagnostic tools to evaluate skeletal and soft tissue abnormalities contributing to obstruction, and have been the most common imaging method in evaluating patients with sleep-disordered breathing (SDB). Aim: To analyze the pharyngeal space in the retroglossal region and the region of hypopharynx at the level of epiglottis as well as its relation with the height and weight of the individuals. Materials And Methods: The study was conducted among 60 participants age 21-50 years and was equally divided into snorers and non-snorers. Lateral cephalogram was taken maintaining the exposure parameters and DIGORA software was used for soft tissue parameters. The parameters analyzed were an interincisal angle, angle of the mandible and height of the ramus. Results: Interincisal angle was found to be more among snorers as compared to non-snorers (p<.05), whereas the angle of the mandible and height of the ramus was found to be less among snorers as compared to non-snorers and was found to be statistically significant.

Background: Three dimensions (3D) modeling, printing, and manufacturing can help in personalized and customized surgical reconstruction of complex defects in the craniofacial region with precision by manipulating tissues based on the preoperative assessment, planning the shape of metal and alloplastic materials, and reduction in the total cost and time of the surgery.Aim: The present survey study aimed to assess the approach of treating surgeons towards the role of 3D printing in post-op rehabilitation of palatal bone loss by mucormycosis.Methods: One thousand eyes nose and throat (ENT) and maxillofacial surgeons were given a pre-formed structured survey questionnaire to be filled by subjects themselves for their view on the role of 3D printing for rehabilitation and reconstruction of palatal bone loss due to mucormycosis.Results: Efficacy of 3D printing to print the pneumatic sinus design and palatal contour helping to design accurate support with a lightweight prosthesis, 67.2% (n=672) subjects whereas, exact duplication of the excised tissue, 85.4% (n=854) subjects, to detect and duplicate undercuts, 58.4% (n=584) subjects, 3D printing can be helpful as the proper extension of impression 73.2% (n=732) subjects responded positively. For reconstruction of a lost palate by prosthesis 91.2% (n=912) of study participants, in making obturators using Titanium framework and Polyetheretherketone (PEEK) was given a positive response by 82.2% (n=822) subjects, to fabricate prosthesis obturator required in palatal perforation in case of mucormycosis was given a positive response by 88.1% (n=881) subjects, the role of 3D printing to overlay zygomatic implant prosthesis was responded positively by 68.9% (n=689) study subjects. Conclusion:The present survey study concludes that 3D printing is a reliable and accurate method for palatal reconstruction following bone destruction by mucormycosis as reported by the majority of ENT and maxillofacial surgeons.
