(1) Background: When placing implants in the maxillary posterior region with insufficient alveolar bone, a maxillary sinus elevation is necessary. Autogenous bone, though biologically ideal, poses risks and discomfort due to donor site harvesting. Block-type autogenous tooth bone graft material, made from the patient's own extracted tooth, offers similar biological stability without these drawbacks. (2) Methods: This study observed the progress of 19 implant patients who were treated with maxillary sinus elevation procedures using block-type autogenous tooth bone graft material at the Daegu Catholic University Medical Center. Extracted teeth were processed into demineralized tooth block bone. After elevating the sinus membrane, implants and the tooth bone graft material were placed in the space, and the bony window was repositioned. Postoperative evaluations through clinical observation and radiographic imaging assessed sinus membrane elevation, alveolar bone height increase, and implant osseointegration. (3) Results: Results showed proportional increases in alveolar bone height to the graft material size, with long-term stability. No postoperative complications occurred, even with sinus membrane perforation, and implants remained stable. (4) Conclusions: The study concludes that maxillary sinus lifts using block-type autogenous tooth bone graft material provide excellent bone induction and biocompatibility, making this a highly beneficial method for both dentists and patients.

This study assessed AI-processed low-dose cone-beam computed tomography (CBCT) images for single-tooth diagnosis. Human-equivalent phantoms were used to evaluate CBCT image quality with a focus on the right mandibular first molar. Two CBCT machines were used for evaluation. The first CBCT machine was used for the experimental group, in which images were acquired using four protocols and enhanced with AI processing to improve quality. The other machine was used for the control group, where images were taken in one protocol without AI processing. The dose-area product (DAP) was measured for each protocol. Subjective clinical image quality was assessed twice by five dentists, with a 2-month interval in between, using 11 parameters and a six-point rating scale. Agreement and statistical significance were assessed with Fleiss' kappa coefficient and intra-class correlation coefficient. The AI-processed protocols exhibited lower DAP/field of view values than non-processed protocols, while demonstrating subjective clinical evaluation results comparable to those of non-processed protocols. The Fleiss' kappa coefficient value revealed statistical significance and substantial agreement. The intra-class correlation coefficient showed statistical significance and almost perfect agreement. These findings highlight the importance of minimizing radiation exposure while maintaining diagnostic quality as the usage of CBCT increases in single-tooth diagnosis.

Brazil's public healthcare system (SUS) offers specialized oral health services to Brazilians, but the productivity of specialists, such as Pediatric Dentists, has not been characterized. Therefore, the objective of this study was to characterize the outpatient dental procedures (ODPs) carried out by Pediatric Dentists within the SUS. An epidemiological study with an ecological, longitudinal, retrospective, and quantitative approach was conducted. The ODPs carried out by Pediatric Dentists within the SUS were characterized based on type of procedure, complexity level, and circumstance (urgent or elective). Data were analyzed using a descriptive and analytical approach, considering a significance level of 5%, as well as the impact of the COVID-19 pandemic (the 2020-2022 years were not included in secondary analyses). In the last 15 years, 29,234,972 ODPs were carried out by Pediatric Dentists within the SUS. Clinical procedures were the majority (55.4%), significantly more frequent than all other types of procedures (all p <0.05). Among these, restorative and periodontal procedures were the most common (30.7% and 21.0%, respectively). From 2008 to 2019, excluding COVID-19 pandemic years, the trend over the last 15 years was constant for all types of procedures (all p >0.05). In addition, low complexity ODPs were the majority (90.1%), significantly more frequent than medium (9.7%) and high complexity procedures (0.1%) (both p <0.05). At last, most ODPs were not characterized by circumstance in the outpatient production reports (96.9%). Therefore, it was possible to conclude that Pediatric Dentists carried out diverse ODPs within the SUS over the past 15 years, although there was a dominant pattern of type and complexity.

BACKGROUND
The advent of three-dimensional (3D) printing technology has revolutionized the field of dentistry, enabling the precise fabrication of dental implants. By utilizing 3D printing, dentists can devise implant plans prior to surgery and accurately translate them into clinical procedures, thereby eliminating the need for multiple surgical procedures, reducing surgical discomfort, and enhancing surgical efficiency. Furthermore, the utilization of digital 3D-printed implant guides facilitates immediate restoration by precisely translating preoperative implant design plans, enabling the preparation of temporary restorations preoperatively.
METHODS
This comprehensive study aimed to assess the postoperative oral health status of patients receiving personalized 3D-printed implants and investigate the advantages and disadvantages between the 3D-printed implant and conventional protocol. Additionally, variance analysis was employed to delve into the correlation between periodontal status and overall oral health. Comparisons of continuous paired parameters were made by -test.
RESULTS
The results of our study indicate a commendable one-year survival rate of over 94% for 3D-printed implants. This finding was corroborated by periodontal examinations and follow-up surveys using the Oral Health Impact Profile-14 (OHIP-14) questionnaire, revealing excellent postoperative oral health status among patients. Notably, OHIP-14 scores were significantly higher in patients with suboptimal periodontal health, suggesting a strong link between periodontal health and overall oral well-being. Moreover, we found that the operating time (14.41 ± 4.64 min) was less statistically significant than for the control group (31.76 ± 6.83 min).
CONCLUSION
In conclusion, personalized 3D-printed implant surgery has emerged as a reliable clinical option, offering a viable alternative to traditional implant methods. However, it is imperative to gather further evidence-based medical support through extended follow-up studies to validate its long-term efficacy and safety.

We compared the managing of prevention methods for SARS-CoV-2 infections in dental offices before and immediately after the COVID-19 pandemic. The purpose of this study was to find out the varieties of infection prevention methods used by dentists before and during the pandemic and compare them. We designed a digital transversal questionnaire with 15 closed questions that was sent to 150 dentists in Bucharest, Romania. We received = 112 valid answers during July-August 2021 from dentists of all age groups (25-60 years), with a sex ratio of 0.36, which agreed to anonymously participate in this study. The results showed an increase in types and amount of personal protection equipment (i.e., ocular/facial protection, supplemental gown, and upgrading the FFP1 masks to FFP2 or FFP3). Ocular protection showed statistical significance by gender but not by age group. Vaccination rate against SARS-CoV-2 was at 80% of the participant dentists at the time of the survey and had statistical significance. However, vaccination status of the patients did not alter dentists' protection protocol.

BACKGROUND
Fear and anxiety are common psychological responses to unpleasant stimuli, with dental fear being the fourth most prevalent type of fear or phobia. However, not all dental procedures cause the same level of anxiety, with dental surgery and tooth extraction being among the top five most frightening procedures in the field. Tooth extractions are also the most common surgical procedure in dental surgery. It is important to manage anxiety in the dental office by identifying the main factors.
METHODS
The study was conducted on a group of 250 patients. The survey technique and the Beliefs about Pain Control Questionnaire (BPCQ) were used in the study. Pain and stress intensity on a Visual Analog Scale (VAS) were measured in each patient before and after tooth extraction procedures.
RESULTS
Young women and people from small towns had the highest levels of anxiety. The factor causing the highest level of anxiety was fear of complications. Patients undergoing extraction of retained teeth were characterized by higher levels of anxiety.
CONCLUSIONS
Perioperative stress is strongly dependent on numerous factors. For patient comfort, it may be crucial for dentists to have knowledge about these factors and the ability to utilize them to reduce stress before and after tooth extractions.

Silver diamine fluoride (SDF) is a topical solution used for managing dental caries. The mixed-methods study consists of a quantitative study (questionnaire survey) and a qualitative study (in-depth interview) to explore the knowledge, attitudes, and practices towards SDF among dentists in Vietnam. A descriptive approach and a thematic approach were performed to analyze data, respectively. The questionnaire survey invited 436 licensed dentists registered for the national annual dental meeting and 226 dentists participated (response rate: 52%). Among them, 174 (77%, 174/226) dentists knew SDF, and 69 (40%, 69/174) dentists used SDF for caries management. Most of them considered SDF therapy as non-invasive (84%, 146/174) and simple (80%, 140/174). However, most of them expressed concern that SDF could discolor the tooth (74%, 128/174). Their most preferred teeth for SDF therapy were primary posterior teeth (92%, 160/174). The in-depth interview consulted 16 dentists to reach data saturation. They learned about SDF from outside curriculum resources as an effective anti-caries agent. They understood the advantages (simple, non-invasive, timesaving) and disadvantages (tooth discoloring, ammonia odor) of SDF. They used SDF to arrest caries in uncooperative children in the clinic and people living in rural areas in outreach services. Most dentists in Vietnam are supportive of SDF therapy, and they know its advantages and disadvantages for caries management. The results addressed the aim of the study to investigate Vietnamese dentists' perspectives towards SDF.

The aim of this study was to evaluate the level of knowledge of resident dentists and new graduates regarding the etiology, clinical diagnosis, and treatment of the main medical emergency conditions. The study included a sample of 152 new graduates and residents in the first, second, and third year of training in Prosthodontics and General Dentistry from the Faculty of Dental Medicine in Iasi, Romania. Their level of knowledge and the attitudes were assessed using a questionnaire with 24 questions, divided into four sections. The differences among groups were identified using the chi-square test ( < 0.05). A high level of knowledge was found among the three groups of subjects for the questions regarding the recognition of clinical signs in hypoglycemic crisis (88-100%), in anaphylactic shock (83.3-94.5%), and the treatment of angina pectoris (76.2-84.2%). In contrast, a low level of knowledge was found for the questions regarding pulse evaluation in the case of an emergency (26.3-35.7%), the parameters of normal breathing (28.9-43%), and the treatment of hypoglycemic crisis (27.8-44.8%). The study indicated that the dentists had a moderate understanding of dental office medical emergencies and preferred practical training over theoretical courses.

UNLABELLED
Differentiating orofacial odontogenic pain/disorders from pain/disorders associated with maxillary sinusitis is important to avoid unnecessary dentalprocedures and to properly refer patients to colleagues/dentists and vice versa.
AIM
To analyze the association between apical lesions and sinus changes and to evaluate the agreement between the diagnoses of an endodontist, a radiologist, an oral and maxillofacial surgeon, and an otolaryngologist.
MATERIALS AND METHOD
385 axial, coronal, and sagittal MSCT scans were selected using an image archiving andcommunication system (PACS). The examinations had been performed between 2018 and 2022.
RESULTS
Apical lesions were observed in 36.10% of sinusitis cases, 73.8% of unilateralsinusitis cases, 48.7% of sinus floor discontinuity cases, and 67.2% of cases in which endodontic treatment had been performed. Agreement between the diagnoses made by the endodontist and those made by the other investigators was high for most study variables (k > 0.60). The exceptions were mucosal thickening, for which agreement between the endodontist and the other investigators was intermediate (k=0.397), and the presence of periapicallesions (k=0.010), previous endodontic treatment (k=0.013), and mucosal thickness (k=0.024), for which agreement between endodontists and radiologists was low. Conclusions: There was an association between sinus changes and apical lesions.
