Since the use of dental implants is continuously increasing, it is imperative for dental practitioners to understand the nature and treatment of peri-implant diseases. The purpose of this manuscript is to comprehensively review peri-implant diseases, their characteristics, as well as their non-surgical and surgical treatment. To that end, the current literature was searched and a narrative review was conducted. It is essential that the case definitions described in the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions are used to diagnose and classify peri-implant health, peri-implant mucositis and peri-implantitis. While recent epidemiologic studies on peri-implant diseases exist, there is great heterogeneity in the definition of these conditions. Several risk factors and indicators are reported in the literature, with smoking and diabetes being the most universally accepted. In peri-implant mucositis, non-surgical treatment seems to be sufficient. However, for the treatment of peri-implantitis, a surgical approach, which includes open-flap debridement, apically positioned flap and guided bone regeneration, is considered more appropriate. A great variety of adjuncts to mechanical treatment have been reported with controversial results. Finally, studies comparing results from different peri-implantitis treatments are warranted in randomized controlled clinical trials in order to provide stronger evidence-based approaches.
Cemental tear is defined as cementum fragment completely or partially detached from the root surface, and it has been associated with localized rapid periodontal breakdown. Although history of trauma and/or attrition may be risk factors, the etiopathology of cemental tear remains unknown. This case series aims to discuss the clinical, radiographic and histopathologic features of cemental tears to aid clinicians in making differential diagnosis. Three teeth from three patients presenting a periradicular lesion underwent an exploratory surgery to determine the cause and provide treatment. Soft and hard tissue biopsies were obtained from each lesion and forwarded for histopathologic evaluation. Two patients received a guided tissue regeneration (GTR) procedure, which allowed the tooth to be retained. One patient received an extraction with simultaneous guided bone regeneration (GBR) due to a hopeless prognosis of the tooth. The results after histopathologic evaluation yielded a final diagnosis of cemental tear for all three patients. Cemental tears may be overlooked, and therefore, they should be included in the differential diagnosis of periapical periodontitis, endodontic‐periodontal lesion and vertical root fracture (VRF).
Periodontal and peri-implant diseases are of rising concern due to their increasing prevalence, potential complications and financial consequences. Etiologic factors primarily are putative microorganisms while therapy involves mechanical debridement of the dental plaque biofilm. This treatment is performed non-surgically or surgically. Due to the diversity of periodontal and peri-implant diseases and conditions, practitioners seek adjuvants to improve therapeutic outcomes and limit the likelihood of residual or refractory disease. Antimicrobials may improve therapeutic success by altering the local pathogenic microflora and limiting the systemic spread of opportunistic infections. The use of antimicrobial adjuncts in dentistry is controversial, and there is a need to assess their validity in order to improve the success rates of periodontal and implant therapy whilst minimizing complications or adverse effects. This review aims to provide a summary of the current status of antimicrobial use for periodontal and peri-implant disease management. Adjunctive therapy may include systemic antibiotics, local antimicrobials, supra and subgingival antimicrobial irrigants, antimicrobial oral rinses, antiplaque and anti-calculus agents, photodynamic and laser therapies. Periodontal and peri-implant conditions are detailed, and adjunct antimicrobial options are summarized and their benefits are weighed against their potential side-effects. We proposed a standardized protocol for the adjunctive use of local and systemic antimicrobials in the management of periodontal or peri-implant diseases and conditions.
Despite many discoveries over the past 20 years regarding the etiopathogenesis of periodontal and peri-implant diseases, as well as significant advances in our understanding of microbial biofilms, the incidence of these pathologies continues to rise. For this reason, it was clear that other strategies were needed to eliminate biofilms. In this review, the literature database was searched for studies on locally delivered synthetic agents that exhibit anti-biofilm properties and their potential use in the treatment of two important oral diseases: periodontitis and peri-implantitis.
The use of biocompatible membranes in periodontal and oral surgery is an important part of regeneration. Over the years, several different membranes have been developed, ranging from non-resorbable membranes that have to be removed in a separate procedure, to collagen membranes that completely resorb on their own, thus avoiding the need for a second surgery. Autogenous membranes are becoming increasingly popular in more recent years. These membranes can be used with a great variety of techniques in the four main hard tissue regenerative procedures: guided tissue regeneration, alveolar ridge preservation, guided bone regeneration and sinus floor augmentation. A review of the literature was conducted in order to identify the most commonly used membranes in clinical practice, as well as the most promising ones for regeneration procedures in the future. The information provided in this review may serve as a guide to clinicians, in order to select the most applicable membrane for the clinical case treated as the correct choice of materials may be critical in the procedure’s success.
