Filter by:To evaluate the change of S. mutans and Lactobacillus spp. counts after all dental treatments were completed under general anesthesia and compare the groups in case of using probiotics and not using probiotics with the time for 6-months follow-up period.
Around 40 people will participate in the study. The study participants will be recruited from service homes in the City of Helsinki. The subjects will be randomized into two groups. One of the groups will receive daily photodynamic Lumoral treatment for 2 months in a home care unit according to a separate instruction manual. At the beginning of the study, all subjects will receive an oral cleaning and will also be provided with electric toothbrushes. In addition, residents and care home personnel will be instructed on daily tooth cleaning. During the study, all participants will undergo clinical measurements and an assessment of the oral inflammatory load. The samples will be stored for later analysis. In addition, residents or care home personnel answer questions about oral self-care. These measurements and examinations will be carried out at the start of the study and two months after the start of the study. After the end of the study, participants will continue to be treated according to their usual care and individual care plan.
The aim of the study is to evaluate the knowledge, attitude, and practice of a group of dental practitioners from Cairo and Riyadh regarding caries risk assessment and management.
This study aims to investigate consecutive biological changes in proximal contact tightness using digital force gauge and evaluate proximal contact location using cone beam computed tomography between class II direct composite restorations and adjacent teeth after using sectional matrix system and with different contact forming instruments.
Class II caries affects proximal surfaces of premolars and maintain their anatomical proximal contact of tooth, is important to avoid food impaction in the interdental area for protection of periodontium and occurrence of secondary carious lesion.Different types of Matrix band system are used to restore tooth cavities with missing proximal walls, including flat or pre-contoured bands, retainer-fixed circumferential systems, and sectional matrices, and either metal or plastic matrices which produces good contours and contacts for use with amalgam and can also be employed for insertion of composite resin.This study aimed at assessing the influence of different matricing techniques :either sectional matrix or circumferential matrix and the influence of operator experience on reproduction of optimum proximal contacts for posterior proximal resin composite restorations.
Isolation is essential for the successful placement of esthetic restoration to avoid any contamination of cavity with saliva ,secreation,and blood dental . This study is comparison of optradam and convetional rubberdam system.The aim of this study is to investigate which rubberdam system is better accepted by patients and dentists
There is limited data available on VITA AMBRIA glass ceramic , so this study is conducted to investigate the esthetic parameters of this new glass press system.
Of all the various pulpotomy medicaments that have been studied till to date, three agents have been selected for this study to compare their efficacy. CH being the control, MTA being one of the most recommended biomaterial and PRF that in addition to being a biomaterial is an autologous agent. Uptil now there have been no prospective trials using these three pulpotomy agents in mature permanent teeth with irreversible pulpitis in our part of the world and even the international studies that have been done utilized different methodologies with no unanimous conclusion. This is the reason that at present this treatment regime (pulpotomy) showing better perspectives cannot be presented with confidence as a predictable treatment option to the patients with irreversible pulpitis. By virtue of this study this challenge is being undertaken. Hypothesis: ALTERNATE HYPOTHESIS There is a difference between the efficacy of the PRF, MTA and CH when used as pulpotomy medicaments in mature permanent teeth with irreversible pulpitis NULL HPOTHESIS There is no difference in efficacy of the PRF, MTA and CH when used as pulpotomy medicaments in mature permanent teeth with irreversible pulpitis
the aim of present study is to evaluate clinically the fracture liability , marginal adaptation , and patient satisfaction of conservative versus conventional ceramic Onlays use e-max press to restore defective restored molar with old restoration or caries. with one or more cusp defect
Implant-supported restorations have become one of the best treatment options for patients with tooth loss, with predictable long-term success rates and clinical outcomes. Immediate implant placement means the implant is placed immediately after tooth extraction. It can significantly reduce treatment time because extraction socket healing and implant osseointegration occur simultaneously. Immediate implant placement has many benefits, reducing the overall treatment time, reducing the patient's surgical procedures, and reducing surgical trauma (no flap reversal). However, the treatment also has significant limitations, including the inability to predict the possibility of bone and soft tissue healing, and the possibility of subsequent unfavorable esthetic outcomes. However, the evidence regarding soft and hard tissue and aesthetic outcomes in patients treated with immediate implants in the aesthetic area remains inconclusive. As the aesthetic success of implant restorations is increasingly valued over implant survival, there are significant clinical benefits to addressing immediate implant bone tissue resorption and soft tissue deficiencies and improving the aesthetic outcome of immediate implant restorations. To address the potential health and aesthetic problems associated with soft and hard tissue deficiencies around dental implants, bone grafting in the jumping gap and soft tissue grafting procedures are often performed. According to literature, autologous soft tissue grafts have shown the best clinical and histological results in soft tissue regeneration techniques. However, it requires removal of tissue from the patient's donor area, which can add additional trauma. In contrast, gelatin sponges, currently commonly used as wound closure materials, are only hemostatic and rapidly absorbed postoperatively, and do not provide protection of hard and soft tissue augmentation. Collagen matrix has recently been introduced for keratinized gingival augmentation and has shown encouraging results in preclinical and clinical studies, but more information is needed to confirm its clinical efficacy. Mucograft® Seal is a porcine collagen matrix with a bilayer structure, a dense and slowly absorbing layer and a spongy layer that stabilizes blood clots and allows soft tissue cells to penetrate. Human gingival fibroblasts cultured on Mucograft® were demonstrated to have good proliferative properties and cell viability as scaffold material. In dog extraction sites, preliminary results suggest that the combination of Mucograft® and Bio-Oss Collagen may be an effective method for alveolar ridge preservation. Mucograft® Seal can be used in combination with Bio-Oss Collagen® for alveolar ridge preservation after tooth extraction. The research hypothesis is that the use of a collagen matrix to seal the wound in immediate implant placement in aesthetic area will reduce buccal bone resorption and increase the width and thickness of the soft tissue at the implant site. Therefore, we designed this comparative clinical trial in which patients accept immediate implant placement in aesthetic area. The implant is placed after tooth extraction, and bone graft material Bio-Oss Collagen® is placed in the jump gap, and the wound was closed by different means (collagen matrix or gelatin sponge randomly). The clinical examination, CBCT imaging and histological evaluations were performed to compare the differences in clinical efficacy of the two wound closure methods. The primary outcome is the buccal bone thickness change at the immediate implant site 4 months after surgery.
