Periodontal therapy for hopeless mandibular anterior teeth: a retrospective case report with a multidisciplinary approach and a 20-year follow-up

Introduction: This case report presents the intentional periodontal maintenance of two periodontal hopeless lower central incisors with a multidisciplinary approach and 20-year follow-up. Case presentation: A 36-year-old male, in 2001, was diagnosed with aggressive periodontitis, gingival swelling, bleeding, and mandibular central incisors with mobility and poor prognosis. Following periodontal therapy (phase I), root canal treatment, and occlusal adjustment, #31 and #41 were gently extracted to remove the granulation tissues, calculus, and infected cementum from the root surface. Then, tetracycline-HCl was applied for 5 minutes on the root surfaces. The teeth were repositioned into the sockets and splinted with a lingual bar. At 3 months, the bar was removed, and a free gingival autogenous graft was done to improve the local keratinized tissue width. Mobility scores, pocket depths, and clinical attachment levels were recorded, and radiographs were taken at 1, 5, and 20 years. The 5-year follow-up showed that the teeth were clinically and radiographically in function. There was a reduction in probing depth and a gain in clinical attachment and radiographic alveolar bone levels. After 20 years, #41 was stable, but #31 had external root resorption, leading to a new treatment plan (dental implants) and extraction. Conclusion: The clinical result of this case was satisfactory for 20 years. Intentional periodontal maintenance of the teeth may be an alternative treatment, even considering the high level of complexity.

Introduction to the Diagnostics in Periodontology and Implant Dentistry issue.

Chronic inflammatory periodontal disease and its related condition, peri-implant disease, are highly prevalent globally and require accurate and speedy diagnosis. The focus of this volume dedicated to diagnostics is to cover modern enhancements in accuracy, simplicity and speed. An international assortment of experts has been tasked with reviewing defined areas of current best practice as well innovation in the field of periodontitis and peri-implantitis diagnostics. Periodontitis and peri-implantitis are irreversible, chronic, cumulative conditions propagated by bacteria and host factors, which involve soft and hard tissue changes, and these changes are measured in the diagnostic process. Clinically relevant modifications to the healthy state are detected using clinical, radiological and laboratory or point of care testing, and these testing approaches are critically reviewed at length in this state-of-the-art resume of periodontal diagnostics.

[Evaluation of the role of standardized periodontal probing training on the teaching of undergraduates using the Florida probe system].

PURPOSE: To evaluate the effect of standardized periodontal probing training on the teaching of periodontal clinical probing for undergraduates by using Florida probe system. METHODS: Twenty undergraduates who practiced in the Department of Periodontology of Changzhou Stomatological Hospital from May 2022 to November 2022 were selected as the study objects and randomly divided into two groups with 10 students in each group. The experimental group received standardized periodontal probing training, while the control group did not receive training. Two groups of students used the traditional probe and the Florida probe to probe the left and right half-mouth teeth of one patient. In addition, a periodontal specialist used Florida probe to conduct full oral examination of the same patient, and the results were compared with those of the two groups of students. SPSS 26.0 software package was used for statistical analysis of the obtained data. RESULTS: There was no significant difference of probing depth(PD) between undergraduates and periodontal specialist in the experimental group (P＞0.05), while there was significant difference in the control group (P＜0.05). In the control group, PD values in the anterior area were not statistically different from those of periodontal specialist (P＞0.05), while PD values in the posterior area were statistically different (P＜0.05). Both groups of patients reported that the Florida probe system was more comfortable. CONCLUSIONS: Standardized periodontal probing training is helpful to improve the clinical probing ability of undergraduates. The use of Florida probe system can not only evaluate the teaching effect, but also improve the comfort level of patients, which is worthy of further application in the teaching course of periodontal probing for undergraduates.

Assessing the article screening efficiency of artificial intelligence for Systematic Reviews.

OBJECTIVES: Artificial intelligence (AI) tools utilizing machine learning (ML) have gained increasing utility in medicine and academia as a means of enhancing efficiency. ASReview is one such AI program designed to streamline the systematic review process through the automated prioritization of relevant articles for screening. This study examined the screening efficiency of ASReview when conducting systematic reviews and the potential factors that could influence its efficiency. METHODS: Six distinct topics within the field of periodontics were searched in PubMed and Web of Science to obtain articles for screening within ASReview. Through a "training" process, relevant and irrelevant articles were manually incorporated to develop "prior knowledge" and facilitate ML optimization. Screening was then conducted following ASReview's algorithmically-generated relevance rankings. Screening efficiency was evaluated based on the normalized number of articles not requiring detailed review and on the total time expenditure. RESULTS: Across the six topics, an average of 60.2 % of articles did not warrant extensive screening, given that all relevant articles were discovered within the first 39.8 % of publication reviewed. No significant variations in efficiencies were observed with differing methods of assembling prior knowledge articles or via modifications in article ratios and numbers. CONCLUSIONS: On average, ASReview conferred a 60.2 % improvement in screening efficiency, largely attributed to its dynamic ML capabilities. While advanced technologies like ASReview promise enhanced efficiencies, the accurate human discernment of article relevancy and quality remains indispensable when training these AI tools. CLINICAL SIGNIFICANCE: Using ASReview has the potential to save approximately 60 % of time and effort required for screening articles.

Diagnostic measures for monitoring and follow-up in periodontology and implant dentistry.

This review discusses the role of diagnostic measures in the lifelong management of periodontal disease and peri-implant complications. After active treatment, these conditions require regular monitoring of the supporting structures of teeth and dental implants to assess bone and soft tissue health over time. Several clinical measures have been developed for the routine assessment of periodontal and peri-implant tissues, including periodontal and peri-implant probing, bleeding on probing, intraoral radiography, biomarker analysis, and microbiological testing. This review highlights the evolution of diagnostic practices, integrating traditional methods with emerging technologies such as resonance frequency analysis and ultrasound imaging to provide a holistic view of peri-implant health assessment. In addition to objective measurements, patient risk factors are considered. The goals of periodontal and peri-implant maintenance are to control disease activity and stabilize tissues through supportive care, which includes diagnostic measures at follow-up visits. This enables clinicians to monitor treatment outcomes, assess health status, and detect recurrence or progression early through routine evaluation, allowing additional interventions, including adjustment of supportive therapy intervals, to further improve and maintain periodontal and peri-implant stability over time.

BSP Implementation of prevention and treatment of peri-implant diseases - The EFP S3 level clinical practice guideline.

OBJECTIVES: to adapt the supranational European Federation of Periodontology (EFP) Prevention and Treatment of Peri-implant Diseases - The EFP S3 Level Clinical Practice Guideline for UK healthcare environment, taking into account a broad range of views from stakeholders and patients. SOURCES: This UK version, based on the supranational EFP guideline [1] published in the Journal of Clinical Periodontology, was developed using S3-level methodology, combining assessment of formal evidence from 13 systematic reviews with a moderated consensus process of a representative group of stakeholders, and accounts for health equality, environmental factors and clinical effectiveness. It encompasses 55 clinical recommendations for the Prevention and Treatment of Peri-implant Diseases, based on the classification for periodontal and peri­implant diseases and conditions [2]. METHODOLOGY: The UK version was developed from the source guideline using a formal process called the GRADE ADOLOPMENT framework. This framework allows for adoption (unmodified acceptance), adaptation (acceptance with modifications) and the de novo development of clinical recommendations. Using this framework, following the S3-process, the underlying evidence was updated and a representative guideline group of 111 delegates from 26 stakeholder organisations was assembled into four working groups. Following the formal S3-process, all clinical recommendations were formally assessed for their applicability to the UK and adoloped accordingly. RESULTS AND CONCLUSION: Using the ADOLOPMENT protocol, a UK version of the EFP S3-level clinical practice guideline for the Prevention and Treatment of Peri-implant Diseases was developed. This guideline delivers evidence- and consensus-based clinical recommendations of direct relevance to the UK healthcare community including the public. CLINICAL SIGNIFICANCE: The S3-level-guidelines combine evaluation of formal evidence, grading of recommendations and synthesis with clinical expertise of a broad range of stakeholders. The international S3-level-guideline was implemented for direct clinical applicability in the UK healthcare system, facilitating a consistent, interdisciplinary, evidence-based approach with public involvement for the prevention and treatment of peri­implant diseases.

The PocketPerio application significantly increases the accuracy of diagnosing periodontal conditions in didactic and chairside settings.

The study aimed to determine the accuracy of diagnosing periodontal conditions using the developed web-based PocketPerio application and evaluate the user's perspective on the use of PocketPerio. First, 22 third-year dental students (DS3) diagnosed ten cases without PocketPerio (control) and with PocketPerio (test) during a mock examination. Then, 105 DS3, 13 fourth-year dental students (DS4), and 32 senior second-year International Standing Program students (ISP2) used PocketPerio chairside. Statistical analysis was performed using a non-parametric paired two-tailed test of significance with the Wilcoxon matched-pairs signed rank test. The null hypothesis that PocketPerio did not increase the accuracy of periodontal diagnoses was rejected at α < 0.01. Periodontal diagnoses made using PocketPerio correlated with those made by periodontics faculty ("gold standard") in all cases. During the mock examination, PocketPerio significantly increased the accuracy of periodontal diagnoses compared to the control (52.73 vs. 13.18%, respectively). Chairside, PocketPerio significantly increased the accuracy of primary (100 vs. 40.0%) and secondary (100 vs. 14.25%) periodontal diagnoses compared to the respective controls. Students regardless of their training year felt more confident in diagnosing periodontal conditions using PocketPerio than their current tools, provided positive feedback on its features, and suggested avenues for its further development.

Perceptions regarding the use of a three-dimensionally-printed manufactured educational simulator for periodontal treatment of intraosseous and interradicular lesions.

PURPOSE/OBJECTIVES: Treating intraosseous lesions (IOLs) and interradicular bone lesions (IRLs) is an extremely technical dental procedure in periodontics. Instrumentation of these lesions is often perceived as difficult by students and inexperienced dentists before they perform a certain number of procedures on patients in the clinic. The aim of this article is to evaluate a cost-effective three-dimensional (3D)-printed educational simulator for the periodontal treatment of IOLs/IRLs (including scaling, incisions and sutures). METHODS: The simulators were first developed digitally, and then manufactured using printable resins and specific materials; finally, they were assembled using different bonding systems. To evaluate the simulators, assessments were gathered from two target populations: undergraduate students and periodontics experts. These individuals tested the simulator and completed a cross-sectional questionnaire based on a Likert scale with comparative and pedagogical items scored from one to five. The purpose of the questionnaire was to compare our simulator to clinical reality (i.e., operation on human jaws) and to an animal simulator (i.e., simulation of porcine jaws). The results are expressed as the mean and standard deviation and were statistically analyzed with the Wilcoxon signed-rank test. RESULTS: Overall, the results were satisfactory for both groups of testers (4.70 and 4.61 out of five for students and experts, respectively, for global satisfaction). CONCLUSIONS: The overall educational relevance of the simulator designed herein highlights the fact that 3D-printed educational simulators could enable efficient cognitive-functional learning for clinical IOL/IRL treatment.

An Endodontology Icon Who Fostered an Appreciation for Pulpal Biology and Its Relevance to Restorative Dentistry and Periodontics: Dr. Kaare Langeland.

The impact of ground-breaking research on the dental pulp and its response to dental procedures, materials and associated diseases significantly influenced the evolution and scope of Endodontics, creating a science of Endodontology. While there were scattered studies in the early 20th century in this regard, the clarification and codification of these concepts took a major leap forward in the late 1950s due to the academic prowess and in-depth research endeavors of Dr. Kaare Langeland. The story begins during World War I in Norway.

Factors associated with the performance and achieving goals of specialized periodontal procedures in Brazilian dental specialties centers.

BACKGROUND: The Brazilian Dental Specialty Centers (CEO, in Portuguese) represent the strategy of the National Oral Health Policy to provide secondary-level dental care. They offer more complex procedures, such as the treatment of periodontitis. This study aims to investigate the factors associated with the performance and the achievement goals of specialized procedures and the achievement gols of periodontics in CEO. METHODOLOGY: Analytical and cross-sectional study using secondary data. The database of the second cycle of the External Evaluation of the National Program for Improving Access and Quality in CEO (PMAQ-CEO, in Portuguese), was utilized, which assessed 1,042 CEO on-site in 2018. The data were analyzed using multiple Poisson regression, estimating the prevalence ratio (PR) (p < 0.05). RESULTS: A third of the CEO (n = 305) performed all specialized procedures, with a higher prevalence observed in those with more than one bicarbonate jet prophylaxis unit (RP = 2.12; 95% CI: 1.160-3.881; p = 0.015) and when they had a higher percentage of specialist professionals (RP = 1.004; 95% CI: 1.002-1.006; p < 0.001). The periodontics goal was achieved by 617 (59.2%) CEO, with a higher prevalence among those who had a manager with supplementary training (PR = 1.21; 95% CI: 1.100-1.335; p < 0.001) and with a higher workload for the periodontist dentist (PR = 1.15; 95% CI: 1.103-1.201; p < 0,001). CONCLUSION: Although most CEOs do not perform allspecialized periodontics procedures, more than half achieved the established goals. The provision of specialized periodontics services in CEO and the achievement of goals are influenced by the quantity and professional qualifications, as well as the availability of equipment.

Artificial intelligence in dental education: ChatGPT's performance on the periodontic in-service examination.

BACKGROUND: ChatGPT's (Chat Generative Pre-Trained Transformer) remarkable capacity to generate human-like output makes it an appealing learning tool for healthcare students worldwide. Nevertheless, the chatbot's responses may be subject to inaccuracies, putting forth an intense risk of misinformation. ChatGPT's capabilities should be examined in every corner of healthcare education, including dentistry and its specialties, to understand the potential of misinformation associated with the chatbot's use as a learning tool. Our investigation aims to explore ChatGPT's foundation of knowledge in the field of periodontology by evaluating the chatbot's performance on questions obtained from an in-service examination administered by the American Academy of Periodontology (AAP). METHODS: ChatGPT3.5 and ChatGPT4 were evaluated on 311 multiple-choice questions obtained from the 2023 in-service examination administered by the AAP. The dataset of in-service examination questions was accessed through Nova Southeastern University's Department of Periodontology. Our study excluded questions containing an image as ChatGPT does not accept image inputs. RESULTS: ChatGPT3.5 and ChatGPT4 answered 57.9% and 73.6% of in-service questions correctly on the 2023 Periodontics In-Service Written Examination, respectively. A two-tailed t test was incorporated to compare independent sample means, and sample proportions were compared using a two-tailed χ2 test. A p value below the threshold of 0.05 was deemed statistically significant. CONCLUSION: While ChatGPT4 showed a higher proficiency compared to ChatGPT3.5, both chatbot models leave considerable room for misinformation with their responses relating to periodontology. The findings of the study encourage residents to scrutinize the periodontic information generated by ChatGPT to account for the chatbot's current limitations.

Periodontists and stem cell-based therapy for alveolar bone regeneration: A national survey.

BACKGROUND: Stem cell-based therapy for bone regeneration has received attention in medical settings but has not yet been used in clinical practice for treating alveolar bone defects. The objectives of this study were to explore whether periodontists had heard about this approach, and if so how, how interested they were to learn about it, which attitudes and behavioral intentions they had related to using stem cell-based grafting, and what they would like to know before using this approach. METHODS: Anonymous survey data were collected from 481 members of the American Academy of Periodontology (response rate: 19.41%). RESULTS: Responses showed 35.3% had heard about stem cell-based therapy, mostly from publications (9.6%) and meetings (8.3%); 76.1% wanted to learn about it through in-person continuing education (CE) courses, 68.6% in online CE courses, and 57.1% from manuals; 73% considered this approach promising; and 54.9% preferred it to traditional approaches. It was important to them that it would result in more bone volume (93%), better bone quality (90.4%), and accelerated healing (83.2%). Also, 60.1% considered it likely/very likely that they would adopt this approach, 54% that patients would prefer it, and 62.1% that it would benefit their practice. When asked what they would like to know about this approach, information about short- and long-term outcomes, cost, and logistical considerations were most frequently named. CONCLUSIONS: These findings provide the basis to develop educational interventions for periodontists about this novel approach and inform future research activities aimed to translate this approach to clinical practice.

Importance of periodontal phenotype in periodontics and restorative dentistry: a systematic review.

BACKGROUND: Periodontal phenotype is regarded to be one of the key factors influencing the efficacy of restorative therapies in dental practice. The objective of the systematic review was to explore the importance of thin and thick periodontal phenotypes and how they affect the outcome of periodontal and restorative therapies by looking at a number of academic publications from various online databases. METHODS: Following the PRISMA guidelines (Preferred Reporting Items for Systematic Review standards), relevant data will be searched and retrieved from three significant scientific databases, including PubMed, EBSCO, and Scopus. The articles with full texts that matched the keywords and published in English between 2018 and 2023 were taken into consideration. RESULTS: The majorities of these articles were based on the type of periodontal phenotype and their impact on periodontal and restorative treatment outcomes were selected. The initial search yielded a total of 530 articles. Only 273 were relevant to the review's objectives, and these were considered for determining eligibility. Only 20 publications were eligible for analysis. CONCLUSION: Understanding these anatomical aspects of periodontal phenotype is crucial to both periodontology and restorative dentistry. The clinical outcome of restorative, prosthetic, orthodontic, surgical, and periodontal therapies is determined in large part by the periodontal phenotype, which also plays a significant role in clinical failure or success in dental treatments. TRIAL REGISTRATION: This study protocol registered with the International Prospective Register of Systematic Reviews (PROSPERO) dated 16th June 2023 with the registration ID CRD42023432568.
