Modelling of simply supported circular diaphragm for touch mode capacitive sensors

This paper describes the power series solution for modelling of the simply supported circular diaphragm deflection under uniform load. The parameters such as touch point pressure and touch radius are defined. Moreover, these parameters are also computed by the algorithm proposed in the paper. Therefore, the power series solution can be applied for touch mode operation

Oral myiasis in a cerebral palsy patient: a case report

Myiasis is a rare condition caused by the invasion of tissues by the larvae of flies, mainly from the order of Diptera. Many cases of myiasis involving various human organs have been reported. Oral Myiasis is very rare in healthy persons. It occurs mainly in the tropics and is usually associated with inadequate personal and public hygiene; sometimes accompanied by poor manual dexterity. We present a case of oral myiasis in a mentally retarded, 13- year-old boy suffering with cerebral palsy. The diagnosis was based on the characteristic clinical features and the visualization of wriggling larvae. Large numbers of larvae were found in the gingival sulcus. Treatment consisted of manual removal of the larvae, one by one, with the help of turpentine oil and clinical forceps, local debridement of the labial gingival and oral hygiene practice. Healing was uneventful, with resolution of the condition

Role of radiology in central hemangioma of jaws

Central hemangioma, a bone destructive lesion, is a benign tumor. Hemangiomas of jaws are rare entity and produ- ces many different radiographic images. Radiographic differential diagnosis includes osteosarcoma, fibrous dysplasia, central giant cell granuloma, ameloblastoma, odontogenic myxoma, multiple myeloma, dentigerous cyst and aneurysmal bone cyst. Since it involves proliferation of blood vessels so aspiration or biopsy of such lesions can lead to severe hemorrhage which can turn out to be lethal. We stress on the importance of radiology in the timely diagnosis of such lesions which can prevent the disaster not only to the patient but also to oral surgeon in legal and professional aspects

Primary intraosseous carcinoma of mandible: an update on review of literature with a case report

Primary intraosseous carcinoma (PIOC) is a rare malignant neoplasm of the jaws which is locally aggressive with quite poor prognosis. Overall and disease free survival is poor with almost 50% patients failing within first 2 years of follow up and reason can be attributed to the delayed diagnosis. But knowledge of the clinical, radiographic and histopathologic features of PIOC allows accurate and early diagnosis of the lesion so that an early and appropriate treatment can be instituted for better prognosis. Here a typical case of PIOC of the mandible is presented and an attempt is made to discuss all possible differential diagnosis and an update on review of literature is presented. Our case highlights that radiographic examination is one of the most effective methods for detecting early lesions of PIOCs

Reimplantation: clinical Implications and outcome of dry storage of avulsed teeth

Reimplantation refers to the insertion and temporary fixation of completely or partially avulsed teeth that have resulted from traumatic injury. Reimplantation of an avulsed tooth depends on certain clinical conditions like phy- siological status of periodontal ligament (PDL), the stage of root development and the length of extra oral time. Depending on the patient’s age, retention of the permanent incisor can maintain the aesthetic appearance, occlusal function and alveolar ridge height. Though the risk of progressive replacement resorption and subsequent tooth loss is high after a long dry storage, reimplantation makes a provision for an aesthetically acceptable permanent prosthesis at a later age. This article presents management of two cases with avulsed permanent incisors that were stored in dry conditions for seven hours and three days respectivel

Significance of pre-treatment panoramic radiographic assessment of edentulous patients-A survey

Objectives: The present study was undertaken to review the significance of pre-treatment panoramic radiographic assessment of edentulous patients, in the dental patient population of Haryana, India. Study Design: In this study a total of 525 completely edentulous patients were selected randomly. A panoramic radiograph was taken using Panoramic machine (Rotagraph plus) and all the radiographs were evaluated by 2 oral radiology specialists for the following clinically significant radiographic findings: retained root fragments, embedded teeth, radiolucencies, radiopacities and location of the mental foramen at the crest of the residual alveolar ridge. The data were analyzed using the chi square test. Results: A total of 245 radiographic findings were seen in 168 (32%) patients. Out of total 525 cases 16.4% (n=86) patients had submucosal or intrabony root stumps, 4.8% (n=25) had embedded teeth, 2.5% (n=13) had radiolucencies, 9.9% (n=52) had radiopacities and 1.7% (n=9) had mental foramen at the crest of the residual alveolar ridge. Conclusion: The results of this study suggest that Routine radiographic examination of completely edentulous patients is critical before construction of complete denture. © Medicina Oral S. L

Prevalence of traumatic dental injuries and role of incisal overjet and inadequate lip coverage as risk factors among 4-15 years old government school children in Baddi-Barotiwala area, Himachal Pradesh, India

Objective: To assess the prevalence of traumatic dental injuries (TDI) in school children in Baddi- Barotiwala, Himachal Pradesh, India. Methods: A cross-sectional survey was carried out in Government schools among 1059 government school children aged 4- 15 years. The study was conducted from October 2009 to March 2010 during the school hours. The demographic detail was carried on a structured questionnaire. The data regarding the traumatic injuries was recorded using modified Ellis' classification. Results: Prevalence of TDI was found to be 4.15%. 95.45% of the injuries were to the maxillary anterior teeth. Maxillary central incisor was the most common tooth to be affected due to trauma (54.5%). Enamel with dentin fracture with pulp exposure was the main type of TDI (43.1%). The majority of TDIs were untreated (97.7%). Falls (54.5%) were found to be the main cause. Over jet over 3 mm and inadequate lip coverage were found to be important contributing factors for TDIs. Conclusion: The present study revealed a relatively low prevalence of dental trauma, but still this figure represents a large number of children. Therefore, educational programs are to be initiated for the community regarding causes, prevention and treatment of traumatic dental injuries. It is crucial to generate considerable efforts to implement health promotion strategies to reverse the observed trends and to provide treatment to TDIs to prevent their biologic and psychological consequences. © Medicina Oral S.

Papillon Lefevre syndrome: bridge between Dermatologist and Dentist

Papillon-Lefevre syndrome is a rare autosomal recessively inherited condition which shows features common to both dentistry and dermatology. This disease is characterized by palmoplantar hyperkeratosis and severe periodon- titis. Therefore both the dentist and the dermatologist should be aware of the same because an early diagnosis of the syndrome can help to preserve the teeth by early institution of treatment, using a multidisciplinary approach. Here we present a case report of Papillon-Lefevre syndrome, along with a comprehensive review of the etiology, pathology, clinical features, differential diagnosis and management of the condition

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.
