RESUMO
BACKGROUND/OBJECTIVES: Mineral trioxide aggregate (MTA) is widely recognized as one of the most biocompatible materials for perforation repairs during root canal treatment (RCT). Experimental evidence has consistently demonstrated MTA's superior sealing ability and biocompatibility compared to various dental materials, including amalgam, intermediate restorative material, zinc oxide eugenol cement, and resin-modified glass ionomer cement. This study aimed to assess the efficacy of MTA as a reparative material in iatrogenic furcal perforations during RCT. MATERIALS & METHODS: A descriptive cross-sectional study was conducted from May 18, 2021, to November 17, 2021, at the Department of Operative Dentistry, Nishtar Institute of Dentistry, Multan, Pakistan. Seventy-six patients aged 18-60 years, of both genders, who developed iatrogenic furcal perforations during procedures were included. Patients with fractures or endo-perio lesions identified during clinical and radiographic examinations were excluded. Isolation was achieved using a rubber dam. The perforation site was cleaned and irrigated with 1% sodium hypochlorite to control hemorrhage and enhance visualization. Following the manufacturer's recommendations, the perforation site was sealed with MTA mixed with sterile saline. RESULTS: The age range in this study was 18 to 60 years, with a mean age of 42.09 ± 9.69 years. Most patients (56.78%) were between 41-60 years old. Out of the 76 patients, 46 (60.53%) were male, and 30 (39.47%) were female, resulting in a male-to-female ratio of 1.5:1. The study found that MTA's efficacy as a reparative material in iatrogenic furcal perforations was observed in 61 (80.26%) patients. A 6-month follow-up revealed no periodontal ligament breakdown, demonstrating the efficacy of MTA as a reparative material in iatrogenic furcal perforations. CONCLUSION: This study concludes that the efficacy of MTA as a reparative material in iatrogenic furcal perforations is remarkable and significant.
RESUMO
OBJECTIVE: This literature research aimed to compare, contrast and quantify the innovations in the most commonly used dental biomaterials. METHODOLOGY: Original research articles based on experimental dental biomaterials published between 2007 and 2019 were retrieved and reviewed. A search of electronic databases, PubMed, Scopus, and Web of Science indexed dental/biomaterials journals, has been conducted. The inclusion criteria in this research were: synthesis of experimental dental materials, whereas commercial dental materials, review articles, and clinical trials (case reports) were excluded. RESULTS: It was found that the amount of publications related to dental subgingival implants, computer-aided modeling ceramics, aesthetic restorative materials, adhesives cements, ceramics, bioceramics, endodontic materials, bioactive scaffolds, stem cells, and guided-tissue membranes had increased significantly from 2007. At the same time, the number of publications related to dental cements, silver amalgam, and dental alloys has decreased. For characterization of dental materials it was noted that mechanical properties were tested mostly for restorative materials. On the other hand, biological properties were most assessed for dental subgingival implants and endodontic materials, however, physical properties predominantly for bioceramics. CONCLUSION: It is concluded that to meet clinical demands there was more focus on restorative materials that provided better aesthetics, including resin composites, adhesive resin composites (luting cements), zirconia, and other ceramics. The boost in laboratory and animal research related to bioceramics was attributed to their regenerative potential. This current literature study will help growing researchers to consider and judge the direction to which research might be guided in order to plan prospective research projects.
RESUMO
Replacement of the missing tooth with an implant has gained popularity among patients. The advent of periodontal tissue engineering has brought about a revolution not only in the field of periodontology but also in the field of implant dentistry at large. Currently, the development of a periodontal ligament (PDL) attachment around dental implants has now become an important new therapeutic tool to replace lost teeth. PDL houses various vital cells that are important in the dynamic relationship between the tooth and the bone. Thus, ligaplants are now an available option to improve the biological performance and to prolong the life of the prosthesis.
