| Abstract|| |
The ultimate goal in modern dentistry is to achieve white and pink esthetics. Optimal periodontal health without encroaching biologic width is the foundation upon which reconstruction of teeth is based. This case report presents the multidisciplinary management of an orthodontic patient who reported with fractured fused endodontically treated upper right anterior teeth with periapical lesion. Crown lengthening procedure with apically displaced flap was done to preserve the band of keratinized tissue and to gain access to the apex of the teeth. Apicoectomy and placement of tricalcium silicate (Biodentine) along with platelet-rich fibrin membrane was done. For better esthetic composite, veneer was given and orthodontic treatment continued. One-year examination showed uneventful healing and reduction of the periapical lesion. PRF membrane and Biodentine yielded good benefits for regeneration. Thus, multidisciplinary approach emphasizes the importance and beauty of collaboration between various specialties to provide the best quality of care to the patient.

| Introduction|| |
Esthetic considerations have influenced the management of dental maladies in varying degrees for many years. The ultimate goal in modern dentistry is to achieve white and pink esthetics. Maintaining periodontal health without violating biologic width is the foundation upon which reconstruction of teeth is based. The concept of biologic width emerges from the classic histologic study by Gargiulo et al., yielding an average dimension of 2.04 mm and is the natural seal that protects the alveolar bone from infection and disease.
Surgical crown lengthening increases the length of supragingival tooth structure for restorative or esthetic purposes by apically positioning the gingival margin, removing supporting bone, or both. Various techniques are available such as gingivectomy, displaced flap, and apically repositioned flap with or without resective osseous surgery, and orthodontic forced eruption with or without fibrotomy. The selection criteria for any technique depend on several factors such as esthetics, clinical crown to root ratio, root proximity, root morphology, furcation location, individual tooth position, collective tooth position, and the ability to restore the teeth. It has become an essential component of the esthetic armamentarium to intensify the appearance and retention of restorations placed within the esthetic zone.
The relationship between periodontium and pulp was first discovered by Simring and Goldberg in 1964. The success of both periodontal and endodontic therapy depends on halting disease process, whether they exist separately or as combined lesion. Apicoectomy with retrograde obturation is a commonly employed procedure to treat the periapical diseases. The main objective is to remove diseased tissue, debride the canal system, and reduce the spread of microorganism in the periradicular tissues, providing an environment conducive of regeneration of a normal periodontal apparatus.
Biodentine, a novel dentinal substitute used as an apical plug is composed of tricalcium silicate, calcium carbonate, calcium chloride, zirconium oxide, and water. The flowable consistency penetrates dentinal tubules, produces surface apatite crystals on contact with the phosphates available in tissue fluids, and helps in the mechanical properties at the interface by providing a good marginal seal.
Platelet-rich fibrin (PRF) described by Choukroun et al. is a second-generation platelet concentrate containing platelets and growth factors in the form of fibrin membranes prepared from the patient's own blood, free of any anticoagulant, or other artificial biochemical modifications. It is a powerful healing biomaterial with inherent regenerative capacity and used in various procedures such as the treatment of periodontal intrabony defects, furcation, sinus lift procedures, and in the field of tissue engineering as a scaffold for human periosteal cells.,,,
| Case Report|| |
A 19-year-old female participant reported to the Department of Periodontology, GDCRI Bangalore, with a fractured upper right anterior tooth at middle-third due to road traffic accident. She was under orthodontic treatment in the same institution for Class III malocclusion. On clinical examination, there was severe pain, inflamed gingiva, pus discharge, and tenderness on palpation. On radiographic examination, it was found to be an endodontically treated fused central and lateral incisors, showing periapical pathology. Gingival margins and attached gingiva level on right anterior teeth were at a lower level compared to the left side which was esthetically unacceptable [Figure 1]. Informed consent was obtained from the participant, and the use of her record for publication was explained. The surgical protocol included a routine medical and dental history followed by blood investigations.

Preparation of platelet-rich fibrin
The protocol proposed by Choukroun et al., for preparation of PRF was employed. Before surgical procedure, blood was collected from the antecubital vein by venipuncture in 10 mL sterile glass tubes without anticoagulant and centrifuged at 3000 rpm for 10 min. Centrifugation led to the formation of structured meshed fibrin in the center of the glass tube, between red blood corpuscles (RBCs) settled at the base and platelet-poor plasma (PPP) above meshed fibrin. RBCs at the base were removed from PRF using sterile tweezers and scissors followed by PPP removal. Remaining meshed fibrin was placed onto sterile gauze pieces and compressed, squeezing serum out of meshed PRF, and forming a stabilized fibrin membrane [Figure 2].
After proper isolation, area was anesthetized with 2% lignocaine hydrochloride with adrenaline. To preserve the band of keratinized gingiva and to gain access to periapical area, apically displaced flap for crown lengthening was planned. The surgical procedure included reflection of a full-thickness mucoperiosteal flap beyond mucogingival junction by sulcular incision and two vertical releasing incisions. Debridement of tissues at the periapical site was followed by irrigation with sterile saline solution. Apicoectomy was done and retrograde filling material Biodentine containing tricalcium silicate (Biodentine, Septodont, Saint-Maur-des-Fosses, France) was used [Figure 3].

Platelet-rich fibrin membrane was placed in the periapical osseous defect area, and flap was sutured. For the better esthetics, direct composite veneer was done to attain a natural color and form of the teeth, and orthodontic treatment was continued. The patient was followed up at 6 months [Figure 4] and at 12 months; the offending tooth was accepted both functionally and esthetically restoring the attached gingival level [Figure 5].

| Discussion|| |
The key to a successful outcome with long-term stability is the establishment of an accurate diagnosis and subsequent development of a comprehensive treatment plan. Using PRF membrane along with Biodentine yielded greater benefits. PRF membrane contains a tetramolecular structured leukocyte-PRF matrix having cytokines, platelets, and stem cells within it which acts as a biodegradable scaffold that guides epithelial cell to migrate to its surface. PRF releases growth factors for a period of 1 and 4 weeks from the cells involved in tissue regeneration. Singh et al. conducted a study to treat periapical lesions using PRF and concluded that PRF improves early wound closure, bone maturation, and the final esthetic result of the periodontal soft tissues.
Biodentine, a tricalcium silicate base material employed to repair root perforations, apexification, and as a retrograde filling material has a good marginal sealing ability and produces surface apatite crystals when in contact with the phosphates available in tissue fluids., Kokate and Pawar compared the microleakage of glass ionomer cement, mineral trioxide aggregate (MTA), and Biodentine when used as a retrograde filling material and found Biodentine exhibited the least microleakage when compared to other materials used. Sulthan et al. in their study evaluated the pH and calcium ion release of MTA and Biodentine when used as root-end fillings and found Biodentine presented alkaline pH and had ability to release calcium ions similar to that of MTA.
For better esthetics, soft-tissue management is very vital which is achieved here with apically displaced flap to gain access to apex of the fused teeth and to preserve the width of attached gingiva. Thus, multidisciplinary approach has become an integral part of everyday dentistry. This case report emphasized the importance and beauty of collaboration of work between periodontics, endodontics, and orthodontics specialties to treat and provide the best quality of care to the patient.
