Autologous platelet-rich derivatives along with alloplastic bone substitute in the management of complex perio-endo cases

Expert consensus on the diagnosis and therapy of endo-periodontal lesions

Endo-periodontal lesions (EPLs) involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms, including unique anatomical and microbiological characteristics and multiple contributing factors. This etiological complexity leads to difficulties in determining patient prognosis, posing great challenges in clinical practice. Furthermore, EPL-affected teeth require multidisciplinary therapy, including periodontal therapy, endodontic therapy and others, but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy. By compiling the most recent findings on the etiology, pathogenesis, clinical characteristics, diagnosis, therapy, and prognosis of EPL-affected teeth, this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

Autologous Concentrate Growth Factor for the Treatment of Endo-Perio Lesion - A Case Report

INTRODUCTION

The success of a combined periodontal and endodontic lesion depends on the elimination of both these disease processes. In the case of a combined endo-perio lesion, endodontic therapy results in healing of the endodontic component of involvement, while the prognosis of teeth would finally depend on the healing of the periodontal structure.

TREATMENT

This case report evaluates the efficacy of autologous fibrin glue and bone graft, that is, sticky bone in the management of bone defects associated with endo-perio lesion. The endo-perio lesion is first treated endodontically, followed by periodontal therapy. Conclusion: The patient was kept on follow-up for 9 months, and satisfactory results in terms of bone fill and reduction in pocket depth were obtained.

TAKEAWAY LESSONS

The sticky bone enhances regeneration in treatment of endo-perio lesions.

Platelet-rich fibrin and titanium-prepared platelet-rich fibrin in endoperio lesion management

Endo-perio lesions involve a variety of therapy choices that will lead to the best possible elimination of infection. Various therapy approaches have been investigated for curing of patients affected by endo-perio abnormalities. One of the second-generation platelet derivatives is plasma enriched with platelet (PRP).They may aid in the healing of wounds. Enhanced with platelets cells and several growth factors, platelet-rich fibrin (PRF) promotes repair and healing and regeneration of tissue at the periapical area. Platelet cell and leukocyte cell enriched fibrin, prepared in conjunction with titanium (T-PRF), is analogous to fibrin made using the traditional PRF process.The current study was undertaken to compare PRF against T-PRF in the therapy of endo-perio abnormalities using the basic information that was available.280 patients of all sexes between the ages of 18 years and 58 years make up the study's participants. They were divided into two categories. In category I study participants PRF was employed to fill the defect created due to pathology and in category II patients, a T-PRF was used, accompanied by suturing. The one walled, two walled, and three-wall walled infrabony abnormalities were quantified on the digital images acquired using the grid. After three months and six months, the probing periodontal pocket depth in mm and level of attachment (RAL) in mm were measured. In category one, mean change at 3 months was 3.21mm accounting for 33.79% change in PPD. On the other hand mean change at 6 months was 3.61mm accounting for 43.79% change in PPD. When there was evaluation in study participants in category two then it was observed that mean change at 3 months was 2.02mm accounting for 34.79% change in PPD. On the other hand mean change at 6 months was 3.62 mm accounting for 44.79% change in PPD. There was reduction of depth of periodontal pocket at both 3 months follow up and 6 months follow in both categories; however there was no statistical significant variation observed between the two categories regarding decrease in the depth of periodontal pocket on analysis of intergroup variations. It was concluded that there was increase in periodontal attachment and decrease in depth of periodontal pocket in both PRF and T-PRF however there was no statistical substantial variation observed between the two categories regarding increase in the attachment level or decrease in depth of periodontal when intergroup variations between PRF and T-PRF were considered.

Surgical treatment of endo-periodontal lesion - а case report

The interrelationship between periodontium and pulp makes the treatment of combined endo-periodontal lesions (EPL) more challenging. It involves successful elimination of both periodontal and endodontic lesion. The current case report represents the efficacy of regenerative potential of enamel matrix derivates (Emdogain®) in endo-periodontal lesion after successful endodontic treatment. A 39-year-old woman presented with EPL on a left first mandibular molar. After the initial 3 months of healing, the clinical examination showed that the furcation involvement still prevailed. A decision was made to use a regenerative procedure using Emdogain®. Fourteen months after the procedure, full periodontal regeneration can be seen on the X-ray. The results demonstrated the synergetic effect of the endodontic and periodontal therapy that changed the prognosis for the tooth.

Platelet-Rich Fibrin: A Viable Therapy for Endodontic-Periodontal Lesions? A Preliminary Assessment

Background and Objectives: The endodontic system and the periodontium are closely interrelated and the infection of both leads to the appearance of endodontic-periodontal lesions. Along with the endodontic and periodontal classic treatment, in most cases, there is a need for regenerative periodontal therapy for the repair of the damaged tissue. One material that stimulates bone healing is represented by platelet-rich fibrin (PRF). The aim of this study was to determine if the inclusion of PRF in the treatment protocol of endodontic-periodontal lesions is effective. Materials and Methods: This review was conducted according to the PRISMA guidelines. Four databases, MEDLINE (through PubMed), Scopus, Web of Science, and Google Scholar, were used in order to find all significant articles on the topic. Relevant keywords were used in different combinations. Results: The inclusion criteria were met by six studies, published between 2014 and 2020 and they were selected for the review. The use of PRF for the regenerative therapy of endodontic-periodontal lesions showed favorable outcomes in all of the studies included, with significant reductions in the probing depths. Conclusion: While platelet-rich fibrin may be beneficial, further research is needed.

Treatment of an Endo-Perio Lesion with Ozone Gas in a Patient with Aggressive Periodontitis: A Clinical Case Report and Literature Review

The pulp and periodontium have obvious relationships that have been described in many studies. Pulp infections may affect periodontal tissues and vice versa. Teeth with endo-perio lesions have a worse prognosis than isolated endodontic or periodontal lesions. Elimination of endodontic and periodontal infections is essential for successful treatment, so co-operation between endodontists and periodontists is necessary. In this clinical case, a 44-year-old male presented with primary periodontal disease with secondary endodontic involvement in his lower right canine because of aggressive periodontitis. There was 10 mm of clinical attachment loss and 8 mm periodontal pocket mesial from the tooth and bone radiolucency periapical and lateral from the root. Periodontal therapy was followed by endodontic treatment. Periodontal therapy included root scaling and planing, treatment of the periodontal pocket with ozone gas, systemic antibiotics, oral hygiene instructions, and chlorhexidine rinsing. Endodontic therapy included root canal instrumentation with rotary endodontic files, irrigation, root canal treatment with ozone gas, and obturation with lateral compaction. Radiographs at a 6-month follow-up appointment showed complete healing of the periapical lesion and alveolar bone lateral to the root. Using an interdisciplinary approach to treat endo-perio lesions provides favorable clinical outcomes. Ozone therapy is beneficial for the successful treatment of endo-perio lesions with narrow periodontal pockets in patients with aggressive periodontitis and poor prognosis.

B.P.F.C.® Bio-Plasma® with Pure Growth Factors (BioPlasma®) Used for the Treatment of a Persistent Great Periapical Lesion of an Endodontically Treated Tooth: A New Therapeutic Option

The aim of this case report was to evaluate the efficacy of a new platelet-rich plasma preparation and its regenerative capacity of bone periapical tissue for the treatment of a very compromised endodontic treated tooth, with a periapical lesion of 1.5 cm in diameter, using a pure platelet concentrate. This is made without the use of anticoagulant or any type of activator, e.g., bovine thrombin, calcium chloride. For this reason, it has been called "Pure"; it is the B.P.F.C.® Bio-Plasma® with Pure Growth Factors (BioPlasma®) designed and developed by Dr. Raffaello Viganò. The patient has read and signed a written consent form. The study protocol was approved by the Ethics Committee for Human Studies, University of Varese. X-ray at 2 and 6 months and 4 years after endodontic surgery demonstrated the success of the treatment.
