INTRODUCTION: Prosthetic treatment with fixed constructions is an effective method for recovering severely destroyed teeth. The purpose of this study is to track the changes in the gingival tissues around teeth, which are prosthetically treated with different aesthetic crowns. MATERIALS AND METHODS: Eighty-two teeth were studied with 46 of them being restored with CAD/ CAM composite crowns and 36 with ready-made zirconia crowns. The assessment of the condition of the surrounding soft tissues was performed using the modified gingival index (MGI). RESULTS: Slight gingival inflammation of the severely destroyed natural teeth (MGI-1,25÷2,13) was reported, whereas after their restoration with crown constructions, healing processes and decreasing of the gingival index during the follow-up period occurred. The MGI, one year after placing the constructions, was 0÷1.44. CONCLUSION: CAD/CAM and ready-made zirconia crowns have excellent compatibility with surrounding soft tissues and do not disturb gingival health.
Prosthetic treatment with removable prosthesis is necessary in cases of genetic and hereditary diseases, multiple caries and severe traumas in order to restore effective chewing and speech function, to achieve acceptable appearance and to ensure unimpeded development of the oral structures and the whole organism. The purpose of the study is to investigate the use of removable prosthetic treatment in children in the daily practice of dentist in Bulgaria. Material and methods: A source of information is a specially designed questionnaire. 767 doctors from all over the country are subjected to the research. The results are statistically processed using the methods of variation, comparison and correlation analysis. Results: Of all respondents, only 0.4% indicated that they use/ or used total dentures in children, and 4.2% note that they are using partial prostheses as a means of restoring of the disturbances. Conclusion: Partial and total edentulism is a rare problem in young patients, which also determines the sporadic use of removable prostheses in daily practice by dental practitioners.
Introduction: Since the beginning of the last century until today, resilient resins have been used for the lining of partial and complete dentures with the aim to achieve more uniform distribution of masticatory pressure and to reduce the trauma of mucous membranes. The aim of this study was to investigate the knowledge and use of resilient denture lining materials (RDLMs) in clinical practice. Material and methods: The study was conducted among dental practitioners and dental technicians in 2016. A direct survey method was used, with a questionnaire containing 11 questions. Results: Over half (53.4%, n = 133) of the respondents do not use RDLMs in their practice. In the cases of retentive prosthetic field or prosthetic field with advanced atrophy, the respondents focus mainly on the surgical preparation of the prosthetic field and recommend the use of RDLMsif there are exostosis-related pain symptoms (≈41%, n = 103) or painful neurogenic points (≈ 44%, n = 105). One-third of the respondents prefer the use of long-term RDLMs, and 73% prefer to apply the indirect lining technique. Conclusion: The various types of RDLMs and their characteristics are well-known by the dental practitioners and dental technicians but rarely used, due to a number of unresolved related issues, such as ungluing of the resilient material from the denture base, appearance of an unpleasant odor, change in the color or texture of the material, etc. In our study, dental practitioners and dental technicians use RDLMsfor complete denture lining mainly in clinical cases with presented pain symptoms.
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.
