Filter by:Research question For patients in a need for anterior crown, does the use of Milled BioHPP PEEK copings veneered with CAD/CAM composite resin offer better patient satisfaction, marginal adaptation and biocompatibility when compared Milled BioHPP PEEK copings veneered with manual layering? Statement of the problem PEEK exhibits a unique modulus of elasticity close to human bone/dentine so it acts as a shock absorber with stress reducing effect. Moreover from a biologic point of view, PEEK is highly compatible with surrounding tissues and it has very promising surface properties . The use of peek in anterior area is limited due to its opaque nature and grayish color, this drawback has been overcome by the use of composite layering material . PEEK restorations can be veneered with manual or CAD/CAM techniques. Information is lacking regarding the influence of the veneering technique on the patient satisfaction , precision of fit and biocompatibility of these restorations which will in turn influence their performance in patient's satisfaction. Rationale To achieve high esthetics when using PEEK it must be veneered by esthetic material 3 . It is available to be used manually or to be milled by CAD/CAM. The manual veneering of the PEEK coping with composite might affect the marginal integrity and the surrounding gingival tissues leading to decrease in the patient satisfaction, while the CAD/CAM veneering technique is proposed to have better patient satisfaction , marginal adaptation and an excellent biocompatible effect on the surrounding tissue. The importance of this trial lies in providing an alternative solution to the manual veneering technique, which will, in-turn, provide better restoration longevity results Aim of the study: The aim of this study is to evaluate the patient satisfaction ,marginal adaptation and biocompatibility of milled BioHPP PEEK copings veneered with CAD/CAM composite resin and compare them to milled BioHPP PEEK copings veneered with manual layering. Null hypothesis: There is no difference in the patient satisfaction, marginal adaptation and biocompatibility between milled BioHPP PEEK copings veneered with CAD/CAM composite resin and milled BioHPP PEEK copings veneered with manual layering. Primary objective: - The Primary outcome: : patient satisfaction of the two groups will be assessed by rating score 0 unaccepted , 1 good , 2 excellent - Secondary outcome: Marginal adaptation of the two groups will be assessed using the modified Ryge criteria. - Tertiary outcome: Biocompatibility (Bleeding). Signs of inflammation and bleeding of the two groups will be recorded after clinical examination and probing using periodontal probe Trial design: - Randomized clinical trial Eligibility criteria: Inclusion criteria: All subjects are required to be: 1-From 18-50 years old, be able to read and sign the informed consent document. 2- Have no active periodontal or pulpal diseases, have teeth with good restorations 3- Psychologically and physically able to withstand conventional dental procedures 4- Patients in a need for anterior crown. 5- Able to return for follow-up examinations and evaluation Exclusion criteria 1. Patient less than 18 or more than 50 years 2. Patient with active resistant periodontal diseases 3. Patients with poor oral hygiene and uncooperative patients 4. Pregnant women 5. Patients in the growth stage with partially erupted teeth 6. Psychiatric problems or unrealistic expectations
This study evaluates the effectiveness of brushing and flossing sequence in the control of dental plaque and gingival inflammation.
Von Willebrand disease (VWD) is the most common inherent bleeding disorder resulting in prolonged bleeding time. Gingival bleeding is a frequently reported symptom of VWD. However, gingival bleeding is also known as a leading symptom of plaque-induced gingivitis and untreated periodontal disease. Gingival bleeding in VWD patients may be triggered by gingival inflammation and not a genuine symptom. Thus, this study evaluates whether type 2 and 3 VWD determines an increased susceptibility to gingival bleeding in response to the oral biofilm.
Background: The actual literature is consistent in considering potential negative effects of sub-gingival prosthetic margins on the periodontal health, but no research has focused the attention on the type of prosthetic margin designs. Hence, the aim of the present study is to evaluate if a horizontal finishing line (deep chamfer preparation) may have a different influence on periodontal soft tissue in comparison with a vertical finishing line (feather edge preparation). Methods: A prospective randomized controlled double blind clinical trial with one single operator and three experienced examiners was performed. One hundred and six crowns were prepared with horizontal tooth preparation while ninety-four with vertical tooth preparation. All the margins were positioned within the periodontal sulcus, at 0.5mm sub-gingivally and all the all-ceramic restorations were cemented with resin cement. Periodontal Probing Depth (PPD), Plaque Index (PI), Gingival Index (GI) and Gingival Bleeding on Probing (BOP) were recorded prior to tooth preparation and twelve month after crown cementation. Also, at 12 months follow-up, the gingival margin position was related to the crown margin position.
