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.
Background:Hypodontia is the developmental absence of one or more teeth from the dentition whereas acquired missing teeth are those lost due to carries, periodontal problem or dental trauma. Patients with congenitally missing teeth suffer aesthetic, functional and psychological morbidity to various degree through childhood, adolescence and adulthood. Greater understanding of the impact of hypodontia on patient's quality of life is very important. Oral health related quality of life (OHRQoL) is considered as an outcome measure to evaluate the consequences of edentulism and the available treatment options. Material and Methods:A cross-sectional comparative survey was carried out in the department of Prosthodontics, de'Montmorency College of Dentistry/Punjab Dental Hospital Lahore from 02/03/2010 to 01/09/2010. Total 80 partially dentate patients were studied which included 40 hypodontia patients and 40 patients with acquired missing teeth. All patients were given OHIP-14 questionnaire and responses were recorded on 5-point Likert scale. The mean scores of the two groups were calculated and compared using chi square test. Results:The total OHIP scores in hypodontia patients was more compared to that in patients with acquired missing teeth and difference was significant in the patient group with 4-5 missing teeth. Conclusion:As the missing teeth number increased, it was found that the OHRQoL in hypodontia patients was more impaired compared to the OHRQoL in patients with acquired missing teeth.
Background: Determining occlusal plane is challenging and difficult aspect during complete removable partial denture prosthesis rehabilitation. Numerous soft tissue landmarks like commissures of the mouth by Gillis in 1933, parotid papilla by P. F. Foley and G. H. Latta in 1985, height of the retromolar pad, the lateral borders of the tongue etc. had been proposed to assist clinician for determining the occlusal plane. No universally accepted reliable anatomical measurement has been proposed to assist in determining of occlusion plane for different ethnic groups in context to Nepal. Material & Methods: This cross-sectional study was conducted in the 60 dentate subjects visiting Nobel Medical College, Nepal, from February 2019 to July 2019. A customized occlusal plane relator was used to evaluate relative parallelism between occlusal plane and alatragal line with respect to different borders of tragus. All the data were collected and statistically analyzed. Results: Maxillary occlusal plane was found to be parallel with the line drawn from ala of the nose to the middle of tragus in 66.66%, followed by inferior border of tragus in 18.33% with the least parallelism in superior border of tragus 15%. Relationship of maxillary occlusal plane with alatragal line was not statistically significant among Aryans and Mongolian ethnicity Conclusion: This study showed line joining ala of the nose and middle border of tragus is parallel to maxillary occlusal plane. And no difference was found for Aryan & Mongolian ethnicity in relation to alatragal line and maxillary occlusal plane.
