RESUMEN

OBJECTIVE: The objective of this study was to systematically review the literature regarding the effect of root coverage procedures on tooth survival and periodontal outcomes. DATA SOURCES: A systematic search of the literature was performed according to the PRISMA guidelines. A PICO-based search strategy was performed in six databases. Eligibility criteria included studies comparing tooth survival and periodontal outcomes of teeth treated with root coverage procedures versus teeth that had no treatment. The search resulted in 3,646 articles; 212 articles were downloaded for review, and six articles (three studies) were included. Only a single study reported on tooth survival and found no difference between teeth that underwent root coverage procedures versus those that did not. Although the surgeries described in each study were mostly successful in reducing recession and increasing keratinized gingiva, teeth which did not undergo surgery did not seem to have a clinically significant change in recession. The study with the longest follow-up (18 to 35 years) showed an average increase in recession of 0.5 ± 0.9 mm and a decrease in keratinized tissue of 0.3 ± 0.8 mm in the control group. CONCLUSION: This systematic review highlights the need for randomized controlled trials to assess the influence of root coverage surgeries on tooth longevity in order to better inform evidence-based practice. When compared to no surgical intervention, there is presently no evidence to suggest that root coverage surgeries increase tooth longevity. Furthermore, the amount of recession does not appear to increase a clinically significant amount over time without surgical intervention in the presence of proper maintenance and home care.

RESUMEN

BACKGROUND: The present retrospective study was aimed to assess the long-term clinical performance of dental implants in a cohort study of 4247 patients. METHODS: A longitudinal observational cohort study was done on all implants performed by a single periodontist from July 1995 to April 2019. The main outcome variables of this study were implant failure and marginal bone level around implants. RESULTS: The study participants received a total of 10 871 implants with a mean of 2.56 implants per patient. The cohort was followed-up to 22.2 years (mean = 4.5 ± 4.2). Among the 4247 patients of the current study, 140 patients (3.3%) experienced a combined total of 178 implant failures. According to life table analysis, at the implant level the cumulative survival rate at 3, 5, 10, and 15 years was 98.9%, 98.5%, 96.8%, and 94.0%, respectively while at patient level was 97.4%, 96.7%, 92.5%, and 86% at 3, 5, 10, and 15 years. Patients with multiple units were at a greater risk for having an implant failure. Baseline bone level was 0.09 ± 0.28 mm while at 8-10 years the mean bone level was 0.49 ± 0.74 mm. The incidence of peri-implant mucositis at the implant level was 9.4% at 2-3 years, 9.3% at 4-5 years, 12.1% at 6-7 years, and 11.9% at 8-10 years. The incidence of peri-implantitis was 2%, 2.6%, 3.2%, and 7.1% at 2-3, 4-5, 6-7, and 8-10 years, respectively. Cigarette smoking and diabetes mellitus were positively correlated with implant failure. CONCLUSIONS: Though the results are promising and encouraging in terms of survival and bone level over time, it is important to emphasize the potential risk factors and consider them prior to dental implant placement.

RESUMEN

OBJECTIVES: The spread of COVID-19 has posed significant challenges for dental professionals worldwide. The aims of the present study were twofold: (i) to study the attitudes, emotional responses, and worries among the dental personnel; and (ii) to look for the ability of dental personnel to experience posttraumatic self-growth as a result of the distress caused by the pandemic. METHOD AND MATERIALS: A cross-sectional online survey using an anonymous questionnaire was performed simultaneously in Israel, Canada, and France during the initial lockdown period. RESULTS: Israeli dental practitioners were less worried about their physical health, mental health, or relationships with family and friends than their Canadian and French counterparts. The Canadian dental practitioners were most committed and most willing to treat their patients, as well as most concerned about not being able to treat patients in the same personal way as before the lockdown. French dental practitioners showed the highest level of fear to treat patients. There were no differences in dental practitioners' levels of anxiety, depression, or posttraumatic growth among the countries. Dental practitioners' posttraumatic growth was significantly associated with worries regarding their physical health. CONCLUSION: Responses of dental personnel to the COVID-19 pandemic varied worldwide. Despite the differences, evidence exists that some of the dental practitioners' worries and concerns are associated with psychologic growth as a result of the pandemic. Better understanding and acknowledgment of dental personnel's worries and concerns can facilitate growth and enable positive functioning under the continuous situation of uncertainty.

RESUMEN

BACKGROUND/AIM: Impact to the orofacial region, in particular teeth, is a frequent incident leading to injury in many sports and can result in health and economic costs for the injured individual. The majority of previous work has applied synthetic models such as plaster or stone, to form analogs of relevant structures to study the potential for impact-induced injury. Biomechanical studies that have applied tissue models (animal or human) for the purpose of determining the biomechanical measures associated with dental injury are rare. The aim of this study was to apply a simple ex vivo model based on swine dentition to ascertain which of a select list of measurable quantities associated with impact mechanics could predict luxation and fracture of teeth due to impact. METHODS: Mandibular central incisors of ex vivo swine dentitions were impacted using a linear drop tower with heights ranging from 1.20 m to 2.42 m. Seven mechanical predictors were assessed at impact and were then subjected to binary logistic regression techniques to determine which was the best predictor of luxations or fractures of the teeth. RESULTS: Of the seven mechanical predictors, (1) the velocity of the impacting body (R2  = 0.477), (2) a proxy measure for the change in kinetic energy of the impacting body (R2  = 0.586), and (3) the approximate energy absorbed by the tissue (R2  = 0.722) were found to be statistically significantly different (p < .05), offering the greatest specificity as indicated by receiver operator characteristics. Other measures that are frequently used in impact mechanics, including peak linear acceleration and velocity change, were not statistically significant predictors of tooth injury. CONCLUSION: Identifying mechanical predictors for dental injury of unprotected teeth provides a first step in understanding which aspects of an impact event attribute to dental injury and can lay the foundation for future studies that examine alteration in injury mechanics associated with protection devices.

RESUMEN

PURPOSE: Placement of dental implants adjacent to teeth with inflammation, such as periapical lesions, may have implications on the implant prognosis. The aim of this study was to systematically collect the available evidence regarding the influence of endodontic status of adjacent teeth on dental implant prognosis. MATERIALS AND METHODS: A systematic electronic search was conducted using the MEDLINE (PubMed), Embase, EBSCO, CINHAL, COCHRANE, and SCOPUS databases in August 2019. The search was further supplemented with a hand-search citation mining process. All types of studies that addressed the endodontic condition of the adjacent tooth and evaluated dental implant success or survival were analyzed and evaluated according to the PRISMA and NOS guidelines. RESULTS: Overall, seven human studies were included in the final analysis. Those included a total of 1,914 implants placed adjacent to teeth with periapical lesions or root canal treatments. Four studies included implants placed adjacent to teeth with periapical lesions (1,634 implants), and three studies included implants placed adjacent to teeth with root canal treatments (280 implants). Lower success rates of dental implants placed adjacent to teeth with periapical lesions or to endodontically treated teeth were reported; however, the results were inconsistent. CONCLUSION: There is some evidence to support an association between the endodontic condition of the adjacent tooth and the success of dental implants, but it is not enough to support a causative relationship. Nevertheless, clinicians should treat any active sources of infection and inflammation in adjacent teeth prior to insertion of dental implants.

RESUMEN

Periodontitis is a common disorder affecting >40% of adults in the United States. Globally, the severe form of the disease has a prevalence of 11%. In advanced cases, periodontitis leads to tooth loss and reduced quality of life. The aetiology of periodontitis is multifactorial. Subgingival dental biofilm elicits a host inflammatory and immune response, ultimately leading to irreversible destruction of the periodontium (i.e. alveolar bone and periodontal ligament) in a susceptible host. In order to successfully manage periodontitis, dental professionals must understand the pathogenesis, primary aetiology, risk factors, contributing factors and treatment protocols. Careful diagnosis, elimination of the causes and reduction of modifiable risk factors are paramount for successful prevention and treatment of periodontitis. Initial non-surgical periodontal therapy primarily consists of home care review and scaling and root planing. For residual sites with active periodontitis at periodontal re-evaluation, a contemporary regenerative or traditional resective surgical therapy can be utilised. Thereafter, periodontal maintenance therapy at a regular interval and long-term follow-ups are also crucial to the success of the treatment and long-term retention of teeth. The aim of this review is to provide current concepts of diagnosis, prevention and treatment of periodontitis. Both clinical and biological rationales will be discussed.

RESUMEN

INTRODUCTION: The novel bioresorbable polymer poly (lactide-co-glycolic acid) (PLGA) coated biphasic calcium phosphate material hardens into a stable and porous hard tissue scaffold when exposed to body fluids. The self-containable, stable bone graft material might be beneficial for facilitating Guided Bone Regeneration (GBR) around dental implants, especially for a defect with an absence of bony wall(s). The aim of this prospective case series was to evaluate the postsurgical implant survival and success where the in-situ hardening biphasic calcium phosphate material was used for GBR around dental implants. CASE SERIES: Ten patients received 13 implants with simultaneous bone augmentation. Dehiscence and/or fenestration type of bony defect was detected in nine surgical sites, and three surgical sites exhibited a suprabony defect. In nine out of the 13 implants, a membrane was used in conjunction with the bone grafting. Patients were evaluated at the day of the surgery as well as 2 weeks, and 1, 3, 6 and 12 months post-operatively. All post-surgical wounds were uneventfully healed. Radiographic bone levels showed stability over time with an average bone loss/remodeling of 0.19±0.6 mm (range: -0.5-1.5 mm) from implant placement to the last follow-up at 12 months. All implants survived after 12 months. CONCLUSIONS: Implant placement with simultaneous bone grafting using the in-situ hardening biphasic calcium phosphate material, was shown to be a viable and safe procedure with stable clinical and radiographic results over the follow-up period. Further long-term studies are warranted, however, the combination of the ease of handling and the favourable results are promising. This article is protected by copyright. All rights reserved.

RESUMEN

BACKGROUND/AIM: The shift in health care and technology calls for innovation through mobile applications as free educational resources for the masses. The International Association of Dental Traumatology (IADT) created ToothSOS, an app (software application for mobile devices) to provide dental trauma information for patients and professionals. The app contains information on the emergency management and prevention of dental injuries, as well as treatment guidelines for dental practitioners. The aim of this study was to assess public utilization of the ToothSOS app in the first 2 years since its launch. METHODS: The ToothSOS app was launched by the IADT in the first week of April 2018. Data regarding the number of downloads and usage of the app in the first 2 years (from April 2018 to May 2020) were collected and analyzed. RESULTS: The total number of ToothSOS downloads over the 2 years was 47 725. The number of downloads peaked in the first month when the app was initially released. Thereafter, the number of downloads decreased to an average of 1423 ± 363 downloads every month. Europe was the territory with the greatest number of downloads followed by the United States and Canada, Asia, Latin America and the Caribbean, and Africa, the Middle East, and India. CONCLUSIONS: Within as short a period as 2 years, the ToothSOS app continues to gain public interest. Further attempts and public campaigns should be made in order to increase the visibility of the app. Dental professionals should encourage patients and communities to use the app in order to increase awareness for the prevention and proper emergency management of traumatic dental injuries.

RESUMEN

BACKGROUND: Iatrogenic root perforations are an unfortunate accident that can occur during dental treatment and can lead to peri-radicular damage, poor treatment outcome and extraction of the tooth. The aim of this review was to analyse the occurrence and risk factors for root perforation. METHODS: A systematic search of the literature was conducted in CINAHL, Cochrane, EMBASE, Medline and SCOPUS in May 2019. Additional literature was identified through a hand search. Clinical studies enrolling adults with permanent dentition were included. Single case studies and case reports were excluded. Duplicate articles were removed, titles and abstracts were screened and studies were selected according to the inclusion criteria. Data were collected and reported in accordance with PRISMA guidelines. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Tools. RESULTS: A total of 916 articles were screened, from which 47 full-text articles were analysed and 22 articles were finally included in the study. The data were analysed qualitatively because meta-analysis could not be conducted owing to lack of heterogeneity among the studies. Most of the articles were retrospective cross-sectional studies on root canal treatments performed by undergraduate students. The occurrence of perforation ranged from 0.6% to 17.6%. Risk factors for perforation included experience of the practitioner, tooth type, and tooth morphology. The risk of bias in most of the studies included was assessed as low. CONCLUSIONS: This systematic review suggests a need for additional studies on the risk factors associated with iatrogenic root perforation as the current literature is insufficient. Educational efforts in dental schools should address the issue of perforations and provide more clinical experience prior to graduation in order to improve the clinical skills of graduates.

RESUMEN

At a time when access to health care and services for the global population is a concern due to the COVID-19 pandemic, health professionals and their teams are struggling to find a way to adapt their practices. Dental professional organizations and decision-makers are required to provide guidance in a rapidly evolving environment based on the current data, available research, and existing knowledge. Continuous progress in the information communication technology field and universal access to social communication platforms have allowed clinicians to creatively transcend some of the existing traditional barriers in clinical and technological workflows. The aim of this paper is to provide insight and propose future directions concerning the use of teledentistry for dental care in crisis situations such as the COVID-19 pandemic as well as the continuous implementation of teledentistry in noncrisis scenarios. This paper provides information to support the use of teledentistry as a promising avenue for dental professionals when possible, during and possibly beyond the outbreak.

RESUMEN

AIM: The aim of this study was to systematically review and analyse the difference in efficacy of stannous fluoride toothpaste formulations in comparison to other fluoridated toothpastes without stannous fluoride. MATERIALS AND METHODS: A systematic search of the literature was performed according to PRISMA guidelines. A search strategy was developed to answer the study question and was performed in PubMed-Medline databases. Inclusion criteria were randomised controlled clinical trials comparing stannous fluoride toothpaste formulations with other fluoridated toothpastes not containing stannous fluoride. RESULTS: The search in PubMed-Medline databases resulted in 384 articles; 23 articles were downloaded for review, 16 articles were included in the report and six could be used for meta-analysis. All studies were randomised controlled clinical trials that compared clinical outcomes between toothpastes with stannous fluoride combinations and toothpastes with only fluoride. The overall results of the 16 studies favoured the stannous fluoride formulations. However, in a meta-analysis of the randomised controlled clinical trials, it was demonstrated that stannous fluoride toothpaste formulations provided significantly better outcomes based on the Gingival Index (SMD -0.14, 95% CI -0.20, -0.07, P = 0.0001), but not the Modified Gingival Index (SMD -0.30, 95% CI -0.7, 0.09, P = 0.13). PRACTICAL IMPLICATIONS: The antibacterial properties of stannous seem to provide favourable results when formulated with a fluoridated toothpaste. This systematic review highlights the lack of homogenous research available to rigorously compare stannous fluoride toothpaste formulations with other fluoridated toothpastes without stannous fluoride.

RESUMEN

An edentulous posterior maxilla can present a challenge for placement of dental implants due to the proximity of the maxillary sinus. Sinus augmentation is a surgical bone grafting procedure aimed to increase the bone height for implant support. A number of sinus augmentation techniques have been presented and the outcomes show good implant success rates. In order to achieve the desirable outcomes, it is important to gain knowledge of the maxillary sinus anatomy and complete a thorough preoperative evaluation. Being aware of the location of vasculature, nerves, and the presence of septa will help reduce the risk of intraoperative and postoperative complications. This review provides a narrative clinical overview related to the anatomy, preoperative evaluation, contraindications, techniques, postoperative care, outcome measures, and complications of sinus augmentation procedures.

RESUMEN

Traumatic dental injuries (TDIs) of permanent teeth occur frequently in children and young adults. Crown fractures and luxations of these teeth are the most commonly occurring of all dental injuries. Proper diagnosis, treatment planning, and follow up are important for achieving a favorable outcome. Guidelines should assist dentists and patients in decision making and in providing the best care possible, both effectively and efficiently. The International Association of Dental Traumatology (IADT) has developed these Guidelines as a consensus statement after a comprehensive review of the dental literature and working group discussions. Experienced researchers and clinicians from various specialties and the general dentistry community were included in the working group. In cases where the published data did not appear conclusive, recommendations were based on the consensus opinions of the working group. They were then reviewed and approved by the members of the IADT Board of Directors. These Guidelines represent the best current evidence based on literature search and expert opinion. The primary goal of these Guidelines is to delineate an approach for the immediate or urgent care of TDIs. In this first article, the IADT Guidelines cover the management of fractures and luxations of permanent teeth. The IADT does not, and cannot, guarantee favorable outcomes from adherence to the Guidelines. However, the IADT believes that their application can maximize the probability of favorable outcomes.

RESUMEN

Biologic complications around dental implants may be categorized into peri-implant mucositis and peri-implantitis. Peri-implant mucositis is defined as reversible inflammation in the peri-implant mucosa without any apparent bone destruction. Peri-implantitis refers to inflammatory process that resulted in destruction of alveolar bone and attachment. Potential etiologic and contributing factors to both diseases are discussed in this review. By targeting and eliminating the etiologic factors nonsurgically as well as surgically, dental implants presenting with peri-implant diseases may be rescued, and then maintained with proper long-term peri-implant supportive therapy. Furthermore, clinical cases and their management are presented to demonstrate the available treatment options. Implant therapy should be carefully planned and executed with consideration of potential etiologic and contributing factors to developing biologic complications. During the initial consideration, patients should be informed of the potential biologic complications in dental implant therapy. Clinicians should monitor implants for any development or recurrence of peri-implant disease to ensure timely therapeutic intervention.

RESUMEN

Introduction Despite excellent reviews in the past several years, the use of antibiotics as prophylaxis for implant placement remains controversial.Aim To assess the literature on the efficacy of prophylactic antibiotics prescribed prior to and immediately following implant surgery (PIFS).Outcomes Whether administration of antibiotics reduced implant failure and post-operative complications.Design Databases searched were PubMed and Medline via Ovid (1946 to February 2018), Cochrane Library (Wiley) and Google Scholar.Materials and methods Quality assessment, meta-analysis with a forest plot and incorporated assessment of heterogeneity. A two-tailed paired t-test was performed, analysing differences in mean failure rates between groups.Results Fourteen publications were collected; 5,334 implants were placed with pre-operative antibiotics, 82 implants with antibiotics PIFS and 3,862 placed with no antibiotics. The overall risk ratio (RR) was 0.47 (95% CI 0.39-0.58), with the implant failure rates significantly affected by pre-operative intervention (Z = 7.00, P <0.00001). The number needed to treat (NNT) was 35 (95% CI 26.3-48.2). The difference between mean failure rates was statistically significant (P = 0.0335).Conclusion Administering prophylactic antibiotics reduced the risk of implant failures. Further investigations are recommended to establish a standardised protocol for the proper use of antibiotic regimen.

RESUMEN

Avulsion of permanent teeth is one of the most serious dental injuries. Prompt and correct emergency management is essential for attaining the best outcome after this injury. The International Association of Dental Traumatology (IADT) has developed these Guidelines as a consensus statement after a comprehensive review of the dental literature and working group discussions. It represents the current best evidence and practice based on that literature search and expert opinions. Experienced researchers and clinicians from various specialties and the general dentistry community were included in the working group. In cases where the published data did not appear conclusive, recommendations were based on consensus opinions or majority decisions of the working group. They were then reviewed and approved by the members of the IADT Board of Directors. The purpose of these Guidelines is to provide clinicians with the most widely accepted and scientifically plausible approaches for the immediate or urgent care of avulsed permanent teeth. The IADT does not, and cannot, guarantee favorable outcomes from adherence to the Guidelines. However, the IADT believes that their application can maximize the probability of favorable outcomes.
