A Survey to Estimate the Prevalence of Tooth Loss and Denture Wearers in Subjects of Different Age Groups of South Coastal Karnataka Region

INTRODUCTION: Advancement in age brings into countless new health problems along with the exacerbation of existing ones. Dental awareness has led to decrease in edentulousness in elderly people. The reasons of tooth loss also differs in different age groups.AIM & OBJECTIVES: The objectives of this study were to estimate the prevalence of tooth loss and denture wearers in various age groups along with the evaluation of the reasons for tooth loss.MATERIALS & METHOD: This questionnaire based study was conducted in the patients visiting the department of Prosthodontics Crown and Bridge & Implantology. Subjects were interviewed and examined clinically by a single examiner. A representative convenience sample of 150 patients in age groups of 40-50, 50-60 and 60-70 years were included in the study. Descriptive statistics were applied and the Chi-square test was used to analyse the findings using SPSS version 17.0.RESULTS: Tooth loss was found to be maximum in age group of 60-70 years and almost 64% wore complete dentures. The patients in age group of 40-50 years had maximum percentage of natural teeth (60%). The poor periodontal support was the main cause of tooth loss in almost 74% patients in age group of 60-70 years. Caries was the predominant cause of tooth loss in age group of 40-50 years.CONCLUSION: Prevalence of tooth loss and denture wearers is maximum in bigger age groups. Loss of periodontal support is the main cause of tooth loss as age advances while caries being the major cause in young individuals

Utilization of Stem Cells in Dentistry: A Review

For centuries, scientists have known that certain animals can regenerate missing parts of their bodies. Humans actually share this ability with animals such as starfish which has the ability to regenerate lost arms and can grow an entire new limb. Researchers define stem cells as the clonogenic cells with the capability of self renewal and multi-lineage differentiation and also have the capabilities of generating complex tissues and various organs

Evaluation of Bleeding Disorders in Patients With Noonan Syndrome: A Systematic Review

Background: Noonan syndrome (NS) is an autosomal dominant genetic condition that has a number of clinical features, including bleeding diathesis and a number of hematological abnormalities including clotting factor deficiencies, von Willebrand disease and abnormal platelet count/function. Methods: We evaluated the frequency/types of bleeding disorders, and associated hematological laboratory findings, in patients with NS, using published data from 1965 to 2014. Results: Of 45 studies identified, 31 included data for 428 patients with NS. Of these patients, 43% had reported bleeding, 26% had no reported bleeding and no bleed data was reported for 31%. Most patients (90%) had bleeding-related laboratory test abnormalities, but only 194 (45%) had a confirmed diagnosis of a specific bleeding disorder. Abnormal laboratory tests included: prolonged prothrombin time, activated partial thromboplastin time, and other platelet-related disorders. Of the 194 patients with a confirmed diagnosis of a specific bleeding disorder, 153 (79%) had single clotting factor deficiencies, von Willebrand disease or platelet-related disorders, and 41 (21%) had multiple deficiencies including platelet-related disorders. Conclusion: As patients with NS can experience multiple bleeding disorders, including abnormal platelet function, clinical evaluations should be performed at diagnosis, after diagnosis, before any surgery is undertaken, and if patients become symptomatic

Propolis: A Wonder Bee Product and Its Pharmacological Potential in Dentistry

The use of natural products in the treatment of sickness has long been emphasised in the medical field. Today's biomedical applications employ a vast range of natural ingredients to treat a wide range of systemic disorders. Researchers have been interested in the natural product "propolis" because of its potential for use in bio-dental applications. Propolis is a non-toxic resinous material with therapeutic qualities like antibacterial, anticancer, antifungal, antiviral, and anti-inflammatory effects. The purpose of this research is to investigate the chemistry and characteristics of propolis in connection to its uses in dentistry and biomedicine. Furthermore, the present and prospective uses of propolis in biodental applications have been examined, along with its status and extent. This review gives the reader some insight into the potential use of propolis in contemporary dentistr

Implant envision for the dentist

Dental implants have revolutionized the field of dentistry. A presurgical treatment planning is required for the success of implants. For safe implant placement, full knowledge of the shape and quality of the implant site is a prerequisite To aid this, diagnostic imaging plays a vital role which implement a cohesive and comprehensive treatment plan for the implant team and the patient. Various modalities have been described in these articles which are intraoral radiography, cephalometric radiography, panoramic radiography, conventional tomography, computed tomography and magnetic resonance imaging .These examinations provide information regarding the locations of vital anatomic structures (mandibular canal, mental foramen, maxillary sinus, nasal sinus and incisive canal) that are to be taken care during implant placement

Performance analysis of a lithium-ion battery of an electric vehicle under various driving conditions

Conventional fuels are the primary source of pollution. Switching towards clean energy becomes increasingly necessary for sustainable development. Electric vehicles are the most suitable alternative for the future of the automobile industry. The battery, being the power source, is the critical element of electric vehicles. However, its charging and discharging rates have always been a question. The discharge rate depends upon various factors such as vehicle load, temperature gradient, surface inclination, terrain, tyre pressure, and vehicle speed. In this work, a 20 Ah, 13S-8P configured lithium-ion battery, developed specifically for a supermileage custom vehicle, is used for experimentation. The abovementioned factors have been analyzed to check the vehicle’s overall performance in different operating conditions, and their effects have been investigated against the battery’s discharge rate. It has been observed that the discharge rate remains unaffected by the considered temperature difference. However, overheating the battery results in thermal runaway, damaging and reducing its life. Increasing the number of brakes to 15, the impact on the discharge rate is marginal; however, if the number of brakes increases beyond 21, a doubling trend in voltage drops was observed. Thus, a smoother drive at a slow-varying velocity is preferred. Experiments for different load conditions and varying terrains show a rise in discharge with increasing load, low discharge for concrete, and the largest discharge for rocky terrain

Inflammatory hyperplasia: From diagnosis to treatment

Gingival enlargement, the currently accepted terminology for an increase in the size of the gingiva, is a common feature of gingival disease. Local and systemic factors influence the gingival conditions of the patient. These factors results in a spectrum of diseases that can be developmental, reactive and inflammatory to neoplastic. In this article, the history, etiology, clinical and histopathological features, treatment strategies and preventive protocol of inflammatory hyperplasia are discussed
