Item Case Report of a Pleomorphic Adenoma of Ear Lobule(Wolters Kluwer Medknow Publications, 2024) Meena R.N.; Jain R.; Khanna R.; Srivastava V.K.Pleomorphic adenoma (PA) is the most common benign tumor which affects both major and minor salivary glands. The parotid gland is affected most of the time. Among the minor salivary glands, the palate is the most affected site, followed by lips, cheeks, gingiva, floor of the mouth, and tongue. PA of the auricle is very rare and even if they do so, they mostly arise from the external auditory canal. In this report, we present a case of PA of the ear lobule. � 2024 Indian Journal of Otology.Item Geochemistry of Palaeoproterozoic Kajrahat Limestone, Vindhyan Supergroup, central India: insights into depositional conditions and sources of rare earth elements(Springer Nature, 2024) Singh A.; Singh B.P.; Kanhaiya S.; Quasim M.A.; Patra A.; Singh S.; Srivastava V.K.The Lower Vindhyan (Semri) Group substantially consists of unmetamorphosed and undeformed sedimentary sequences of Palaeoproterozoic age. A detailed geochemical study has been carried out to infer the paleoenvironment and the source of REEs for the Palaeoproterozoic Kajrahat Limestone, Vindhyan Supergroup, Central India. This study investigates the geochemical composition of major, trace and rare earth elements (REEs). The studied limestones, have a high percentage of CaO (ranging from 30.87 to 48.59) implies that calcite was the primary mineral phase in these carbonates. SiO2 is second most abundant major oxide. Sr is dominant trace element showing a negative correlation with CaO. All trace elements exhibit depletion with respect to Post-Archean Australian Shale (PAAS). The PAAS-normalized REE pattern of studied limestone has a relatively uniform pattern, with slightly enriched LREE compared to HREE with negative Ce anomaly. Collectively, low concentration of U and U/Th, Ce/Ce* ratios clearly indicates an oxic depositional condition for the samples. The ?REE shows a positive correlation with SiO2, TiO2 and Al2O3 (r2 = 0.87, 0.84and 0.91 respectively) and a week positive correlation with CaO (r2 = 0.12) suggested that siliciclastic sediments also serve as a source for the REEs beside seawater. This, in turn, indicates that the deposition of this limestone occurred in a coastal/shallow marine environment with some contribution from continental part. � The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.Item Myth and reality of "theory-driven individualised practice" in Ayurveda: Mapping physicians� approaches using case-based scenarios(Forum for Medical Ethics Society, 2024) Chauhan M.; Srivastava V.K.; Patwardhan K.Background: The curricula of Ayurveda programmes emphasise various theoretical constructs such as Tridosha (three factors determining the state of health), Agnibala (digestive strength), Samprapti (patho�physiology), among others. It is often argued that practitioners follow an individualised approach based on these principles while treating patients. Yet, dependable data on their real�world influence is lacking. The aim of this study was to record the extent to which these constructs drive decision�making among Ayurveda practitioners and to examine whether these constructs determine individualisation of the interventions. Methods: We employed an emailed survey to record physicians� perceptions. Convenience sampling was chosen as the sampling method. Registered Ayurveda practitioners located across India with a minimum of five years of clinical experience were invited to participate. Five case�based scenarios depicting different clinical conditions were presented to the physicians. Questions that accompanied each case scenario asked the physicians to record clinical diagnoses, treatment plans, and the Ayurveda principles that determined their treatment. Results: A total of 141 physicians responded, from whom we received 152 responses as seven physicians responded to more than one scenario. The results suggest a significant lack of consensus among physicians regarding clinical diagnoses, interventions, and their understanding of pathophysiology in the given clinical scenarios. Many conflicting opinions were also noted. Conclusion: Theoretical constructs do not appear to determine either prescriptions or individualisation uniformly. Two ethical questions arise: �Is this situation due to an inherently weak theoretical framework of Ayurveda?� and �How can one justify spending hundreds of hours teaching these theories?�. � Indian Journal of Medical Ethics 2024.Item Peripheral giant cell granuloma in a child with ectrodactyly-ectodermal dysplasia-cleft lip/palate syndrome: a case report(BioMed Central Ltd, 2024) Kumar A.; Srivastava V.K.; Sonal S.; Bhati V.Background: Ectrodactyly-ectodermal dysplasia-cleft lip/palate (EEC) syndrome mainly affects ectodermal and mesodermal tissues. It is usually manifested as split hands and feet, ectodermal dysplasia, and orofacial clefting, along with other signs and symptoms. A multidisciplinary approach to treatment is required, in which dentists play an important role in identifying and treating various oral conditions that may be genetically linked to or may be the result of EEC syndrome. Case presentation: The present case describes the oral condition of a young child suffering from EEC syndrome and presenting with peripheral giant cell granuloma (PGCG) in the mandibular anterior region. After obtaining a thorough medical and family history and a clinical examination, the lesion was surgically excised under local anesthesia. The patient was followed up at periodic intervals for the next twenty four months, during which no recurrence of the lesion was observed. Conclusion: This report highlights the role of a dentist in the management of the oral conditions of patients suffering from EEC syndrome. � The Author(s) 2024.Item Prevalence of most caries-susceptible area on individual primary tooth surface: an observational study(MRE Press, 2024) Srivastava V.K.; Badnaware S.; Kumar A.; Khairnar M.; Chandel M.; Bhati V.; Gupta P.; Sonal S.; Ramasamy S.Due to multifactorial aetiology, tooth surfaces of primary dentition are more prone to dental caries and follow the specific pattern of dental caries which is difficult to control. The proper knowledge of caries-susceptible areas on individual primary teeth surfaces guides the clinician to take early preventive measures to stop the progression of dental caries. This study aims to find the prevalence of caries-susceptible areas on primary teeth surfaces in preschool children and the most commonly affected primary teeth. The study design adopted was a cross-sectional study. A total number of 3720 teeth of 186 preschool children were examined for initial pinpoint caries lesions using World Health Organization (WHO) caries detection criteria. 33 caries-susceptible areas were examined on individual primary tooth surfaces of preschool children who visited the Faculty of Dental Sciences. Each tooth surface was recorded separately and no radiographic examination was done. Obtained data was analysed keeping the level of significance at 5%. The overall prevalence of caries-susceptible area was found significantly higher in the maxillary teeth (Maxillary teeth: 41.7% vs. Mandible teeth: 30.7%; p <0.001) and anterior teeth (Anterior teeth: 43.7% vs. Posterior teeth: 28.4%; p < 0.001). The prevalence of caries-susceptible area on primary teeth on the right side when compared to left counterparts was similar (Right side-38.6% and left side-38.4%; p = 0.931). Area 2 was the most prevalent area on primary teeth surfaces and primary canine was more prevalent in caries-susceptible areas. � 2024 The Author(s). Published by MRE Press.Item Restoration of Complicated Crown-Root Fracture in a Primary Incisor with Fragment Reattachment(American Academy of Pediatric Dentistry, 2024) Gupta P.; Srivastava V.K.; Badnaware S.In traumatic dental injuries in children, due to a lack of maturity to cope with the situation, pain intolerance, amount of treatment procedure, and parental anxiety, simplified and non-invasive treatment procedures, such as biologic restorations, are useful. Using advanced adhesive material for fragment reattachment provides excellent esthetic results and a positive attitude from the patient and family. The purpose of this case report is to describe the biological restoration of a complicated crown-root fracture of a primary maxillary central incisor with the fragment reattachment technique. � 2024 American Academy of Pediatric Dentistry.

Despite being a vital part of systemic health, oral health is neglected in such a population. The present study aimed to determine the oral health status of blind individuals in north India and to identify the factors affecting it. Sixty-nine blind students from a local school for the visually impaired were included in the study. A questionnaire was used to record the basic demographic details and oral habits, followed by an oral examination by a single trained dentist to record dental caries, periodontal status and dental trauma. The prevalence of Dental caries was 63.8% (mean 1.43 � 1.61). Gingival bleeding on probing (BOP) was found in 60.9% of individuals. Dental trauma prevalence was 23.2%, and harmful oral habits were found in 31.9% of individuals. Individuals experiencing a toothache in the last year had a 1.784 times higher risk of dental caries than those who didn�t experience a toothache. Individuals having acquired blindness are 2.411 times more prone to dental trauma in comparison to those suffering from congenital blindness. Blind individuals have poor oral health. Toothache in the last one year is an important risk factor for dental caries in such individuals. Acquired blindness makes a person more susceptible to dental trauma than congenital blindness. � 2024 The Author(s).

(2001) reexamined Demirjian's technique. With these tables, dental age can be represented directly in years without the need for additional conversion tables. Using the prior data and a new study group, Willems G et al. (2010) created a common table for males and females to overcome cases of unknown gender and created a non-gender-specific method (Willems II method) that was not gender-specific. This study aims to evaluate the Willems I and Willems II methods for age estimation in a sample of the Varanasi region population. In this cross-sectional study, 432 samples (237 boys and 195 girls of age range 3�16 years) from the population of Varanasi region were evaluated to validate the Willems I and Willems II age estimation methods. A paired t-test was applied to determine the statistical significance between estimated dental age and chronological age. The Willems I method underestimated the dental age in boys by-0.27 � 0.80 years and in girls by-0.60 � 0.95 years. The Willems II method also underestimated the age by-0.57 � 0.86 years in boys and-0.38 � 0.93 years in girls. Pearson correlation revealed a strong positive association in both methods. The Willems I and Willems II methods are not exactly applicable, but the Willems I method is more relatable to the actual age of the boys sample and the Willems II method for the girls sample. � 2024, Indian Academy of Forensic Medicine.
