Background: The posterior palatal seal (PPS) area plays a major role in retention of a maxillary denture. Many dentures have failed due to faulty recording of posterior palatal seal area. Hence, locating posterior palatal seal area is a critical step in complete denture fabrication. Various techniques have been described in the literature for locating the posterior border of maxillary complete denture. One of the most commonly used methods is the one that uses anatomical landmark like fovea palatine for locating the palatal seal area. However, many studies show a wide range of variation regarding position of fovea palatine with the vibrating line. Materials and Methods: A total of 200 subjects were selected for the study and clinical examination carried out to mark the vibrating line and fovea palatine. The location of vibrating line whether it is anterior to fovea palatine, on the fovea palatine or posterior to the fovea palatine in the different soft palate type(Class I, II or III) was recorded using the phonation method. Results: The vibrating line was located interiorly to the fovea palatine in 70%, 54% and 60% of the subjects with Class I, II and III soft palate. The vibrating line was located on the fovea palatine in22%, 40% and 36% of the subjects with Class I, II and III soft palate and posteriorly to the fovea palatine in 23%, 5% and 3% of the subjects with Class I, II and III soft palate respectively. Conclusion: The vibrating line was predominantly found to be anterior to the fovea palatine in all the soft palatal forms.
Introduction: Teeth play a significant part in the maintenance of a healthy personality and an affirmative self-image. Tooth loss is psychologically a very traumatizing and upsetting experience, and is considered to be a serious event in the life of a person, requiring significant psychological readjustment. Objective: Evaluate the prosthetic status and attitude of the patients towards replacement of the teeth among the patients visiting dental department, Noble Medical College and Teaching Hospital (NMCTH) Materials and Methods: A cross sectional study was conducted over a duration of 6 months to determine prosthetic status and attitude of the patients towards replacement of the teeth among all patients visiting Department of prosthodontics, NMCTH. The inclusion criteria was all patients with at least one missing tooth (excluding third molars) and subjects who gave consent for the study. All the Patients were provided with six close ended questionnaire followed by clinical examination by a well trained investigator. Result: The total number of participants was 297. Of them 157 were male and 140 were female. Most frequently encountered age group was 21-30 years Of these, 80.8% of individual were provided with proper information about replacement of teeth whereas 19.2 % were not. 70.7% individual said they will replace only when they find difficulty in their daily activities. 64.6 % of individual wanted to replace teeth for appearance, 20.5% for function and 14.8% for both appearance and function. 79.5 %stated financial problem and 18.2% stated lack of awareness regarding not replacement of teeth. Conclusion: The patients’ attitudes and demand towards the replacement of missing teeth might be different from the clinicians’ assessment. We consider factors such as the preservation of natural teeth and the maintenance of periodontal health as priority but patients tends to prioritize comfort in mastication and improvement of esthetics. Therefore, it is vital to investigate patients’ awareness, need and demand on prosthodontic treatment options.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
