Unveiling the ChatGPT phenomenon: Evaluating the consistency and accuracy of endodontic question answers.

AIM: Chatbot Generative Pre-trained Transformer (ChatGPT) is a generative artificial intelligence (AI) software based on large language models (LLMs), designed to simulate human conversations and generate novel content based on the training data it has been exposed to. The aim of this study was to evaluate the consistency and accuracy of ChatGPT-generated answers to clinical questions in endodontics, compared to answers provided by human experts. METHODOLOGY: Ninety-one dichotomous (yes/no) questions were designed and categorized into three levels of difficulty. Twenty questions were randomly selected from each difficulty level. Sixty answers were generated by ChatGPT for each question. Two endodontic experts independently answered the 60 questions. Statistical analysis was performed using the SPSS program to calculate the consistency and accuracy of the answers generated by ChatGPT compared to the experts. Confidence intervals (95%) and standard deviations were used to estimate variability. RESULTS: The answers generated by ChatGPT showed high consistency (85.44%). No significant differences in consistency were found based on question difficulty. In terms of answer accuracy, ChatGPT achieved an average accuracy of 57.33%. However, significant differences in accuracy were observed based on question difficulty, with lower accuracy for easier questions. CONCLUSIONS: Currently, ChatGPT is not capable of replacing dentists in clinical decision-making. As ChatGPT's performance improves through deep learning, it is expected to become more useful and effective in the field of endodontics. However, careful attention and ongoing evaluation are needed to ensure its accuracy, reliability and safety in endodontics.

Using a Virtual Patient via an Artificial Intelligence Chatbot to Develop Dental Students' Diagnostic Skills.

Knowing how to diagnose effectively and efficiently is a fundamental skill that a good dental professional should acquire. If students perform a greater number of clinical cases, they will improve their performance with patients. In this sense, virtual patients with artificial intelligence offer a controlled, stimulating, and safe environment for students. To assess student satisfaction after interaction with an artificially intelligent chatbot that recreates a virtual patient, a descriptive cross-sectional study was carried out in which a virtual patient was created with artificial intelligence in the form of a chatbot and presented to fourth and fifth year dental students. After several weeks interacting with the AI, they were given a survey to find out their assessment. A total of 193 students participated. A large majority of the students were satisfied with the interaction (mean 4.36), the fifth year students rated the interaction better and showed higher satisfaction values. The students who reached a correct diagnosis rated this technology more positively. Our research suggests that the incorporation of this technology in dental curricula would be positively valued by students and would also ensure their training and adaptation to new technological developments.

Knowledge, Attitudes, and Practices among Dental Practitioners Regarding Antibiotic Prescriptions for Pregnant and Breastfeeding Women in the Dominican Republic.

In this study, we aimed to explore the trends among dentists in the Dominican Republic of providing antibiotic prescriptions to pregnant/breastfeeding dental patients. A survey was conducted among 98 dentists, using a self-administered questionnaire, about their knowledge and attitudes regarding antibiotic usage in pregnant/lactating women and the translation of these into practice. The majority of the survey population were female dentists (63.3%) aged 45-54 years. A chi-square test showed statistically significant differences in the knowledge sources between older and younger dentists, with a minority having chosen scientific literature as a source (p-value of 0.04). There were statistically significant associations between gender and certain attitudes and practice-based questions, with p-values of 0.04 and 0.01, respectively. The Spearman's correlation test showed a statistically significant correlation between knowledge and attitude (p-value 0.001), whereas no correlation was found with practice (p-value 0.23). A multiple response analysis showed that the majority of the respondents chose the second and third trimester for antibiotic prescriptions for acute conditions such as cellulitis, periodontal abscess, and pericoronitis. Most dentists had sufficient knowledge about antibiotic usage in pregnant/lactating women, but it did not translate into practice, and a certain proportion of the participants followed incongruent drug prescription. These findings can be used to focus on judicious antibiotic usage by dentists in the Dominican Republic.

Trends in Antibiotic Self-Medication for Dental Pathologies among Patients in the Dominican Republic: A Cross-Sectional Study.

The World Health Organisation has warned of the increase in antibiotic resistance, estimating that by 2050 it could become the leading cause of death worldwide. Several studies and literature reviews show a correlation between antibiotic use and bacterial resistance, with unnecessary broad-spectrum antibiotics, such as amoxicillin/clavulanic acid and azithromycin, being one of the main causative factors. An interview-based survey of 2160 participants was conducted to assess the prevalence in the practice of self-medication with antibiotics among dental patients in the Dominican Republic. A series of open-ended questions regarding self-medication and class of antibiotics were put to the patients. Over a third of the study population (39.7%) admitted to the practice of antibiotic self-medication. Most of the respondents (58.4%) who indulged in self-medication were females, and it was prevalent in the older adults between 32-42 years old (36%). There was a negative correlation between age and self-medication practice (p < 0.001) observed with point biserial correlation test. Binary logistic regression analysis found an odds ratio of 0.97 (p < 0.001). The most consumed antibiotics were amoxicillin/clavulanic acid (52%), amoxicillin (31.1%), and azithromycin (10.1%). It is imperative to educate patients about the harmful effects of self-medication and to stress the need for governments to implement stricter laws on non-prescription drug availability.

Oral Manifestations of COVID-19: Updated Systematic Review With Meta-Analysis.

There is increasing evidence for oral lesions and manifestations of COVID-19. The aim of this meta-analysis was to investigate the types of oral manifestations of COVID-19 and their prevalence. PubMed/Medline, Scopus, Web of Science, and Google Scholar databases were used to search for publications on oral manifestations in patients with PCR-confirmed COVID-19. A total of 310 records were selected, and 74 were included. Oral lesions in COVID-19 were classified according to their etiologies, including iatrogenic lesions caused by intubation and opportunistic infections. Of the included studies, 35 reported oral lesions probably caused by severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) infection. Meta-analysis of prevalence data on oral manifestations and aphthous lesions indicated high heterogeneity, while meta-analysis of xerostomia prevalence data revealed a pooled prevalence, with considerable heterogeneity. In conclusion, the meta-analysis yielded high heterogeneity between studies: oral lesions yielded a prevalence of 0.33 (95% CI 0.11-0.60), xerostomia lesions a prevalence of 0.44 (95% CI 0.36-0.52) and aphthous lesions 0.10 (95% CI 0.01-0.24). In addition, a gap in the evidence regarding the prevalence of oral lesions in COVID-19 was identified and the need for further observational studies focusing on this issue and on the causal relationships between oral lesions and COVID-19 was highlighted.

Antimicrobial Prescription Habits of Dentists Performing Dental Implant Treatments in Santo Domingo, Dominican Republic.

The use of antibiotics in implant treatments is controversial. The purpose of this research was to study the behaviors of Santo Domingo dentists who prescribe antimicrobials to patients for the placement of dental implants. A total of 99 dentists participated in the study. A share of 1.2% of dentists prescribed antimicrobials solely in the preoperative period, 8.6% after surgery, 44.4% before and after, 19.8% only in specific situations, and 25.9% did not prescribe at all. Amoxicillin was the predominant antimicrobial of choice. A cross-sectional, observational, survey-based study was conducted. The items studied were demographics, self-assessment of knowledge about antibiotics and when they are used, as well as their recommended dosage and duration, in healthy and non-allergic patients. Notable variability was found in the prescription behaviors of antimicrobials. Bridging gaps in knowledge on the subject could help to standardize prescription guidelines.

Evaluation of the Current Knowledge About Bacterial Endocarditis Prevention Among General Dentists in the City of Santo Domingo, Dominican Republic.

Infective endocarditis (IE) is a life-threatening disease caused by bacterial adherence to the lining of the heart and heart valve, and it can be caused by bacterial contamination of the bloodstream during invasive dental procedures. The American Heart Association (AHA) recommended guidelines for antibiotic prophylaxis in 2008 before invasive dental procedures; however, in the Dominican Republic, no official guidelines or regulations on this topic have been yet established. This study aimed to evaluate the current knowledge about bacterial endocarditis prevention among dentists in Santo Domingo. The study participants were dentists who attended a conference organized by Universidad Federico Henríquez y Carvajal (n = 95), of which 74 responded to the questionnaire survey. Seventy-eight percentage of the participants responded that an indication of antibiotics is recommended in cases of prophylaxis for IE. The prescription of antibiotics was applied to patients with prosthetic valves (78.4%), presented a history of previous IE (77%) among others. Among all the interventions in which the respondents would prescribe antibiotics, tooth extraction (70.7%) was the most frequent. Amoxicillin was the preferred drug choice (63.5%) and clindamycin was the antibiotic of choice in allergic patients (55.4%). Even though the choice of antibiotics were according to AHA guidelines (2008), majority of the dentists (58.82 and 55.4%) were not aware of the correct dosage and timing of administration of azithromycin and clindamycin in drugs in patients allergic to penicillin.

Comparison of PathFile and ProFinder Systems to Create a Glide Path in Curved Root Canals.

OBJECTIVE: Root canal shaping is as important as irrigation and filling when attempting to obtain a high success rate in endodontic treatment. The creation of a glide path before the use of rotary instruments reduces the risk of posterior iatrogenic errors. The objective of the present study was to evaluate instrumentation time and root canal transport after using 2 different glide path rotary systems. METHODS: In total, 60 mesiobuccal root canals of mandibular molars, with curvature angles between 11° and 82°, were standardized to measure 15 mm. The specimens were divided into 2 groups, depending on their angles of curvature (11º-38º and 39º-82º), and further divided into 4 groups (n=15). Two groups were instrumented using the PathFile system and the other 2 using the ProFinder system. The angle and radius of curvature were measured at the most abrupt angle of curvature before and after instrumentation. Both measurements were analyzed and compared using AutoCAD software to determine canal transportation. Curvature angles were compared using Student's t test and the radii of curvature using the Wilcoxon test. The time for instrumentation was also evaluated using Student's t tests. RESULTS: There were no statistically significant differences between the two systems with respect to root canal transport (P>0.05); however, the ProFinder system took a longer time to create a glide path (P=0.004). CONCLUSION: Both systems were equally effective in creating a glide path; however, the PathFile system proved to be faster than the ProFinder system.

Instrumentación tridimensional de sistemas de conductos mediante el sistema self adjusting file (SAF). A propósito de un caso / Tridimensional instrumentation of root canal systems through self adjusting file (SAF). A case report

Algunas de las dificultades que nos encontramos en los retratamientos son la eliminación del material de obturación intraconducto y la presencia de dentina muy contaminada por microorganismos resistentes, en muchas ocasiones asociados en biofilms. En el caso que presentamos nos ayudamos en la última fase del retratamiento de un nuevo sistema que combina instrumentación e irrigación simultáneamente, cuya principal característica es la de adaptarse a la sección transversal de los conductos y de este modo permitir alcanzar áreas en las que la instrumentación rotatoria presenta grandes limitaciones. Facilitándonos, de este modo, la eliminación de cemento y gutapercha remanentes así como dentina contaminada, respetando la anatomía original. El caso ejemplifica esta técnica clínica sobre la que hemos realizado una discusión a partir de la literatura revisada. El diente tratado, un segundo molar inferior, presenta una periodontitis apical aguda producida por una subextensión del material obturador y una deficiente condensación del mismo. Su anatomía inusual formada por un único y amplio conducto es desobturada y desinfectada para proceder a su obturación termoplástica. La evolución del caso a los 6 meses indica una mejora de la sintomatología sin signos radiográficos que indiquen patología periapical (AU)

Some of the difficulties we can find in a retreatment are the removal of the filling material and the presence of intracanal dentin heavily contaminated with resistant organisms, often associated in biofilms. In this case report we help in the last phase of treatment that combines a new simultaneously instrumentation and irrigation system whose main characteristic is to adapt to the cross section of the canals and thus allow to reach areas in which the rotary instrumentation has great limitations. In retreatments, this system provide us thereby removing residual cement and gutta percha and most infected entin, respecting the original anatomy. The present case illustrates the clinical technique on which we have made a discussion from the literature reviewed. The treated tooth presents a acute apical periodontitis with a subextensión of the root canal treatment and a poor condensation. Its unusual anatomy consists of a single large canal which is desobturated and disinfected to proceed with thermoplastic seal. The evolution of the case at 6 months indicates an improvement of symptoms without radiographic signs of apical periodontitis (AU)
