INTRODUCTION: Complex patient diagnoses in dentistry require a multifaceted approach which combines interpretations of clinical observations with an in-depth understanding of patient history and presenting problems. The present study aims to elucidate the implications of ChatGPT (OpenAI) as a comprehensive diagnostic tool in the dental clinic through examining the chatbot's diagnostic performance on challenging patient cases retrieved from the literature. METHODS: Our study subjected ChatGPT3.5 and ChatGPT4 to descriptions of patient cases for diagnostic challenges retrieved from the literature. Sample means were compared using a two-tailed t-test, while sample proportions were compared using a two-tailed χ2 test. A p-value below the threshold of 0.05 was deemed statistically significant. RESULTS: When prompted to generate their own differential diagnoses, ChatGPT3.5 and ChatGPT4 achieved a diagnostic accuracy of 40% and 62%, respectively. When basing their diagnostic processes on a differential diagnosis retrieved from the literature, ChatGPT3.5 and ChatGPT4 achieved a diagnostic accuracy of 70% and 80%, respectively. CONCLUSION: ChatGPT displays an impressive capacity to correctly diagnose complex diagnostic challenges in the field of dentistry. Our study paints a promising potential for the chatbot to 1 day serve as a comprehensive diagnostic tool in the dental clinic.

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.

The performance of artificial intelligence language models in board-style dental knowledge assessment: A preliminary study on ChatGPT.

BACKGROUND: Although Chat Generative Pre-trained Transformer (ChatGPT) (OpenAI) may be an appealing educational resource for students, the chatbot responses can be subject to misinformation. This study was designed to evaluate the performance of ChatGPT on a board-style multiple-choice dental knowledge assessment to gauge its capacity to output accurate dental content and in turn the risk of misinformation associated with use of the chatbot as an educational resource by dental students. METHODS: ChatGPT3.5 and ChatGPT4 were asked questions obtained from 3 different sources: INBDE Bootcamp, ITDOnline, and a list of board-style questions provided by the Joint Commission on National Dental Examinations. Image-based questions were excluded, as ChatGPT only takes text-based inputs. The mean performance across 3 trials was reported for each model. RESULTS: ChatGPT3.5 and ChatGPT4 answered 61.3% and 76.9% of the questions correctly on average, respectively. A 2-tailed t test was used to compare 2 independent sample means, and a 2-tailed χ2 test was used to compare 2 sample proportions. A P value less than .05 was considered to be statistically significant. CONCLUSION: ChatGPT3.5 did not perform sufficiently well on the board-style knowledge assessment. ChatGPT4, however, displayed a competent ability to output accurate dental content. Future research should evaluate the proficiency of emerging models of ChatGPT in dentistry to assess its evolving role in dental education. PRACTICAL IMPLICATIONS: Although ChatGPT showed an impressive ability to output accurate dental content, our findings should encourage dental students to incorporate ChatGPT to supplement their existing learning program instead of using it as their primary learning resource.

The Effect of One-Step or Two-Step MTA Plug and Tooth Apical Width on Coronal Leakage in Open Apex Teeth.

INTRODUCTION: Mineral trioxide aggregate (MTA) has been suggested as an effective material for apical barrier, forming an effective seal against bacterial leakage in teeth with open apices. MTA needs moisture for setting; which can come from the apical region or a moist cotton pellet. This study was intended to compare bacterial leakage in one- and two-step MTA apical barrier technique in open apices with different diameters. MATERIALS AND METHODS: The root canals of 52 extracted human maxillary incisors were prepared and open apices in two different diameters of 1 and 1.4 mm were created. The samples put in experimental groups randomly. A 4-mm thickness of MTA was placed as apical barrier for both one- and two-step methods. In one-step groups (1.4 mm diameter; n=12 and 1 mm diameter; n=12), the samples were obturated immediately after placing MTA plug. For two-step groups (1.4 mm diameter; n=12 and 1 mm diameter; n=12), a moist cotton pellet was placed over the MTA plug for 3 days before root canal obturation. Four samples served as positive/negative control groups. After one week, microleakage was evaluated using bacterial penetration technique and results were statistically analyzed utilizing SPSS software and Chi-square test. RESULTS: In one-step technique 13 and in two-step technique 12 samples showed bacterial leakage. There was no statistically significant differences between two techniques (Chi square, P=1). The difference between the results related to 1 and 1.4 mm apical foramens was also not significant (P=1). Also 12 and 13 samples showed bacterial contamination in teeth with 1 mm and 1.4 mm apical foramens, respectively (P=1). CONCLUSION: It seems that leakage of MTA apical plug using one- and two-step technique is comparable; however, in vivo investigations are highly recommended for more accurate results.

Management of an extensive invasive root resorptive lesion with mineral trioxide aggregate: a case report.

External invasive resorption is an uncommon but aggressive type of external resorption. This report outlines the management of an advanced case of external invasive resorption with mineral trioxide aggregate (MTA). The clinical and radiographic follow-up after 60 months revealed a functional tooth with a stable periodontal condition and no evidence of any further resorption.

Biocompatibility and mineralization activity of fresh or set white mineral trioxide aggregate, biomimetic carbonated apatite, and synthetic hydroxyapatite.

INTRODUCTION: The purpose of this study was to evaluate the effect of apatite formation on tissue contact with white mineral trioxide aggregate (WMTA) and compare this apatite with a synthetic hydroxyapatite (SHAp) in subcutaneous connective tissue of rats. METHODS: Thirty-three Wistar rats were used in this study. Polyethylene tubes filled with WMTA, apatite formed by WMTA (BCAp), and an SHAp along with empty tubes were implanted into dorsal connective tissue of rats for 15, 30, and 60 days. Set MTA covered with BCAp (set MTA/BCAp) was implanted as well. The specimens were stained with hematoxylin and eosin and von Kossa and evaluated for inflammatory reactions and mineralization through a light microscope. RESULTS: All groups evoked a moderate chronic inflammatory reaction at 15 days, which subsided with time. No statistically significant difference was found among the groups (p >.05). BCAp did not stimulate mineralization. WMTA, SHAp, and set MTA/BCAp induced significantly more dystrophic calcification than BCAp (p < .05). WMTA and set MTA/BCAp stimulated the same amount of calcification (p >.05). CONCLUSIONS: Our results suggested a possible role of apatite formation on the mineralization induction characteristics of WMTA, which indicated a definite effect on biocompatibility. BCAp produced by WMTA differed from SHAp in mineralization activity.
