Diagnostic performance of the visual caries classification of International Caries Detection and Assessment System II versus conventional radiography for the detection of occlusal carious lesions in primary molars Jayachandra Reddy Bhumireddy, S V. S. G. Nirmala, Sreekanth Kumar Mallineni, Sivakumar Nuvvula SRM Journal of Research in Dental Sciences 2019 10(3):117-121 Objective: The aim of the present study was to evaluate the accuracy in the diagnosis of the occlusal caries lesion using the International Caries Detection and Assessment System II (ICDAS II) and conventional bitewing radiographs in primary molars. Materials and Methods: A total of 35 children was selected randomly and recruited for visual ICDAS II and conventional bitewing radiographic examination by two independent trained examiners. Two hundred and fifty-four teeth were examined at D1 (enamel caries lesions) and D3 (dentine caries lesions) thresholds. Results: Sensitivity and specificity at D1 for ICDAS II was 100%, whereas it was 2.97% and 100%, respectively, for bitewing radiographs. At D3 threshold, sensitivity and specificity of ICDAS II was 94.55% and 96.45%, whereas it was 60.0% and 98.99% respectively for bitewing radiographs. Conclusion: ICDAS II is better than conventional bitewing radiographs in detecting carious lesions that confined to enamel, and both are equally effective in the detection of dentinal carious lesions.

Analysis of prognostic factors and patterns of failure in patients of oropharyngeal squamous cell carcinoma treated by definitive radiotherapy in a tertiary care cancer center of Northern India Sankalp Singh, Nishant Lohia, Sharad Bhatnagar, Pankaj Kumar Sahu, Manoj Prashar, Sundaram Viswanath, Subramananiam Anand, S Harish, Gaurav Trivedi SRM Journal of Research in Dental Sciences 2019 10(3):122-129 Background: The incidence of oropharyngeal carcinoma is increasing despite decline in the incidence of head and neck cancers of other sites. Functional organ preservation with minimal toxicity and better survival is the management goal in oropharyngeal cancers (OPCs). Morbidity of surgery favors radiotherapy as primary modality in OPCs. Here, we have reviewed and analyzed various prognostic factors and results of conventional radiotherapy in patients treated at our institute with two-dimensional planning. Materials and Methods: The records of 70 patients who were treated radically with radiotherapy with or without concurrent chemotherapy from January 2014 to May 2018 were analyzed in our institute. Results: The median age was 61.5 years with male:female ratio of 6:1. History of tobacco use was present in 83%. Stage IVA comprised the bulk with 63% of cases. Eighty-one percent of the patients received concurrent cisplatin. Median disease-free survival at 1 and 5 years was 71.4% and 54.3%, respectively. Median overall survival at 1 and 5 years was 74.3% and 60%, respectively. Conclusion: Varied patient-related, tumor-related, and treatment-related factors determine the clinical severity and tumor stage and help in predicting survival in oropharyngeal carcinoma.

Patterns of dental problems and time gap in utilization of dental services by patients visiting a dental college in North Kerala Kuldeep Singh Shekhawat, Praveen Dinatius, T Vanishree, CB Thasneem SRM Journal of Research in Dental Sciences 2019 10(3):130-134 Introduction: Access to dental services is generally regarded as a necessary condition for achieving population-level oral health and well-being. Oral diseases are largely preventable by regular home oral care and preventive dental visits which help in the early detection and treatment of oral diseases. Aim: The objective was to assess the patterns of dental problems and time gap in utilizing dental services. Materials and Methods: A retrospective study was conducted on outpatients who visited Century Dental College, Kasaragod, Kerala, for duration of 6 months from July 2017 to December 2017. The data were collected from medical records from the outpatient department. Descriptive statistics were used to analyze the data. Results: A total of 2593 cases were analyzed. The mean age was 35.66 ± 13.2 years. The most common dental problem reported was decayed teeth (29.3%) followed by dental pain (23.5%) and deposits on teeth (14.4%). Only 3.98% of the patients visited immediately the next day as soon as they noticed black discoloration and/or informed about their decayed tooth. Males reportedly approached the college more than females for most of the chief complaints except for replacement of missing teeth. Conclusions: The most common dental problem reported was decayed teeth followed by dental pain and deposits on teeth. Only 3.77% of the patients reported for a routine dental checkup. Twelve percent of patients reported immediately the next day after experiencing dental pain. Most of the participants visit a dentist only if they had a problem.

Natural head posture changes after maxillomandibular procedures – A prospective study Thenmozhi Thirumavalavan, T Selvakumar, M Shanmuga Sundaram, T Guru Prasad, V B Krishna Kumar Raja SRM Journal of Research in Dental Sciences 2019 10(3):145-148 Purpose of the Study: The aim of this study is to evaluate the natural head posture changes in the individuals after orthognathic surgery assessed using cone-beam computed tomography (CBCT) scan. Materials and Methods: The study was conducted in the age group above 18 years who underwent mandibular advancement for the correction of the skeletal deformity. The difference was evaluated in cases with the help of CBCT scan which was taken preoperatively and 3 months postoperatively. The inclusion criteria were patients undergoing mandibular advancement with or without maxillary procedures. The CBCT scan was taken in a natural head position with lips in a relaxed position and without any other tongue movements like swallowing. The exclusion criteria include patients with pharyngeal pathology, syndromic conditions, and history of orthognathic surgery. The head posture was determined by measuring the craniocervical angle (CCA) before and after surgery to evaluate the changes. The study was divided among bilateral sagittal split osteotomy (BSSO) advancement cases and maxillomandibular procedures. The statistical analysis was done using a paired t-test. Results: The head posture changes present in mandibular advancement cases show a decrease in the angulation of CCA in both types. The P value of head posture in BSSO advancement cases was 0.25, and for maxillomandibular cases, it was 0.007. Conclusion: The study was concluded by showing a decrease in the angulation of the CCA after orthognathic surgery. This shows improvement in the facial profile and structural positions.

Role of collagen in oral and systemic diseases Amol Jain, Kshama Chandurkar, Rohit Jaiswal SRM Journal of Research in Dental Sciences 2019 10(3):149-153 Collagen has been studied appreciably by a massive variety of researchers since 20th century. It is the most important fibrous glycoprotein among the ground substances and forms the core component within the connective tissue structures such as tendons, cartilage, the organic matrix of bone, and cornea, and they retain the muscularity and firmness of these elements. It has triple helices architecture. The collagen family so far has identified 20 different forms. All types of collagens play a role by synthesizing fibers and network of microfibers present in the ground substance, basal lamina also remaining constituents of the matrix. In this review we discuss about the organisation and role of different collagen forms in various tissues. It presents the fundamental structure, synthesis and the different disorders or syndromes which occur due to the defects in the collagen biosynthesis.

Herpes simplex virus: A seed or sequelae to pemphigus? Sarita Yanduri, Anu Gokuldas, B Veerendra Kumar, S Suma, MG Madhura SRM Journal of Research in Dental Sciences 2019 10(3):154-157 Pemphigus vulgaris is a vesiculobullous lesion in which autoantibodies are produced against desmoglein-3 antigens. Despite having an autoimmune etiology, herpes simplex virus (HSV) is found to be an additional aggravating factor for this disease. Sometimes, there can be a coexistence between the two entities. Here, a unique case of a 65-year-old female patient who presented with the chief complaint of ulcers in the oral cavity for the past 2–3 months is discussed. Histopathologic and immunofluorescence investigations were suggestive of pemphigus, but the cytopathologic smears manifested characteristics indicative of HSV infection. The existence of a viral infection with the known case of pemphigus poses a potential difficulty in the classical treatment of the latter. This case report throws light on the interesting coexistence of these two disease processes, thus highlighting the pathogenesis and treatment plan which may have to be considered in such controversial cases.

Adenoid cystic carcinoma of palate: A rare case report Pratiksha Kumar, Sangeeta Wanjari, Hemani Sukhija, Anuradha Agarwal, Sukanta Sen, Sumanta Kumar Kolay SRM Journal of Research in Dental Sciences 2019 10(3):158-160 A 40-year-old female patient reported to the department with the complaint of a single growth and pain in the upper right back tooth region for 1 year. Intraoral examination revealed a single unilateral exophytic growth seen on the right upper pterygomandibular raphe region. Extraoral examination revealed no facial asymmetry and no evidence of lymphadenopathy. Histopathological examination revealed a hyperparakeratotic stratified squamous epithelium of variable thickness with broad and flattened rete ridges. Lesional tissue showed large sheets of cells surrounded by condensed collagen component. The lesional cells were basaloid in appearance with hyperchromatic nucleus predominately arranged in a cribriform pattern along with eosinophilic material. No evidence of perineural invasion was observed in serial sections. On the basis of these findings, the diagnosis of adenoid cystic carcinoma was established.
