Pdl Lab Report

The author concluded that with regular periodontal maintenance, removal of root surface accretion for better periodontal tissue attachment was more important than any surgical procedures.

New attachment apparatus forms in infrabony defects through differential tissue response, increasing functional periodontal support. This functional periodontal support results in reduced pocket probing depths, reduced crestal bone loss, increased bone level, and increased clinical attachment levels (Trombelli, et al., 1997. P. 367). In one case study, treatment sites revealed a minimal mean bone level gain, and demonstrated an increased bone level from the baseline with regeneration of periodontal ligament and cementum in a span of 56 days (Vercellotti et al, 2005. P. 546-547). Although not all constructive surgery is eventful, osseous surgery proves to support the dentition and overall oral

Impregum was used for the second impression and was sent to the lab for a bruxZir crown. This material had also been used for years by Dr. Spencer due to its flexibility and pleasant taste. Dr. Spencer had tried different products in the past, however, he found these specific materials to be more effective. The bruxZir crown is a more esthetic choice and was selected for this specific patient based on grinding habits. The other procedure I observed was a porcelain-fused-to-metal (PFM) crown placement using Cavidry, Carboxylate cement, and Durelon. Cavidry is a cleaning agent used for rapid drying, degreasing, and cleaning the area before a crown placement. Carboxylate cement and Durelon are mixed together to create a cement that is the most effective for porcelain-fused-to-metal crowns or gold crowns. The Carboxylate cements and Durelon were selected by the dentist due to its desirable retention of restorations, easy to use, and is inexpensive. The dentist also selected the PFM crown because it is a noble metal that is least likely to break. The office manager explained that a specific crown is selected based on insurance, esthetic purposes, and according to patient’s oral habits.

Within the limitations of the present study, it can be concluded that stronger, more durable material (10v/v% Chitosan modified glass ionomer cement) could be selected for posterior occlusal restorations, while higher fluoride releasing material (50v/v% Chitosan modified glass ionomer cement) could be selected for individuals with high caries risk and in areas subjected to less stress.

The immediate placement of implants into sites with the presence of infection has become an increasingly common procedure. Data from studies that have been published in the past two decades seem to suggest implant survival rates that are equivalent to implants that are placed in native, healthy osseous tissue.(3) While it is not known exactly why the rates are equivalent, some explanations can be proposed. First, when a tooth exhibiting signs of infection is removed, most of the source of that infection is also removed. In some cases, granulation tissue associated with the lesion is also removed with the root of the offending tooth. Any remaining or residual infection is subsequently removed with curettage and irrigation of the socket. Additionally,

compared prefabricated titanium posts with fiber reinforced posts. For luting procedures a self-adhesive resin had been used. The study contained a detailed and organized study design where baseline criteria such as amount of cavity walls remaining, minimum apical root canal seal, and degree of tooth mobility were well-established. The authors also recorded another factors such as, number of proximal contacts, amount of attrition, post length within the root canal, and antagonistic contacts. After follow up and compares for these two type of posts (87 posts) had been completed, no failures were founded during follow-up period up to 3 years. Though the study determined that the post material had no effect on success rate, they added that the results should be interpreted with caution because this is a study of short period of time and different outcomes may be obtained in longer term trials.

The teeth are embedded into the bone of the maxilla or the mandible. The biologic width is a protective seal existing around the teeth to protect the alveolar bone against bacterial infection (Rajendran et al., 2014). ‘The biological width is defined as the dimension of the soft tissue, which is attached to the portion of the tooth coronal to the crest of the alveolar bone (Nugula, et al. 2012)’. Gargiulo et al. (1961) described the dimensions and relationship of the dentogingival junction in humans. Based on his

Using composite resins, glass ionomer cements or compomers In the restoration of cervical zones, shown that marginal leakage was strong on the gingival margin found in cementum or dentin than on occlusal margin found in enamel(18)

Dental implants have evolved immensely over the past 20 years. However, the concept of a tooth replacement implant is not new. From the existence of societies, the importance of beauty and retaining of one’s teeth have been of upmost importance. Having a full set of nice teeth has been essential in appearance and the main contributor to being perceived attractive. This is because a person’s smile is one of the first things other people notice. The idea of permanently being able to replace teeth has been a desire of civilizations since the earliest days. Archaeological evidence shows that man has been trying to overcome periodontal problems and tooth loss for thousands of years. Fortnightly, our modern-day methods of dental implantation are much more successful and painless than the attempts from 4,000 years ago.

Dentin is the bone-like connective tissue of the middle layer of a tooth that is found to play an important role in the structure and integrity of teeth. Dentinogenesis is the process of forming dentin during tooth development. The cells responsible for this process are called odontoblast. These odontoblast cells are differentiated ectomesenchymal cells at the basal membrane of the inner enamel epithelium. These cells grow and secrete a collagenous matrix called the predentin that is later mineralised with hydroxyapatite crystals. Many proteins interact with the collagenous matrix in the mineralization process. As the odontoblasts continue to grow longer and deeper into the pulp cavity,

The differences with respect to soft tissue composition, organization, and attachment between the gingiva and the root surface on one side and between the peri-implant mucosa and the implant surface on the other make the conditions for PD measurements around teeth and implants not fully

The second approach for treatment of periodontitis is the surgical approach that, involves the flap surgery (reduction of periodontal pocket) which permits access for deep cleaning of the root surface, deletion of diseased tissue, and repositioning and shaping of the bones, gum, and tissue supporting the teeth. In some cases of sever bone loss, it may be tried to encourage regrowth and restoration of bone tissue that has been lost through the disease progression by procedure called bone grafting. Guided tissue regeneration is a more advanced technique that may be used along with bone grafting.

Purpose: To study and meta-analyze the effectiveness by means of clinical attachment level, probing depth reduction, bleeding, suppuration and recession of PRP for periodontal intrabony defects on randomized clinical trials (RCT)
