This review defines commonly used laboratory tests, including complete blood count (CBC), coagulation tests, hemoglobin A1c (HbA1c), liver function tests, immunological assays, and microbiological and virological evaluations. Each test provides valuable insights into patient health, aiding in the detection of conditions such as anemia, diabetes, and liver disease, which can complicate dental procedures. By adopting an evidence-based, personalized approach to patient care, dental professionals can enhance safety and treatment success. This article underscores the necessity of integrating laboratory assessments into routine dental practice, promoting a holistic understanding of patient health and improving overall treatment outcomes.

Progress in Dentin-Derived Bone Graft Materials: A New Xenogeneic Dentin-Derived Material with Retained Organic Component Allows for Broader and Easier Application.

The optimal repair of rigid mineralized tissues, such as bone, in cases of fracture, surgical resection, or prosthetic placement, is a complex process often necessitating the use of bone graft materials. Autogenous bone from the patient is generally the gold standard in terms of outcomes but also has disadvantages, which have resulted in extensive research in the field of tissue engineering to develop better and more convenient alternatives. In the dental field, several initiatives have demonstrated that the dentin material derived from extracted teeth produces excellent results in terms of repairing bone defects and supporting dental implants. Dentin is acellular and thus, in contrast to autogenous bone, cannot provide osteoblasts or other cellular elements to the grafted region, but it does contain growth and differentiation factors, and has other properties that make it an impressive material for bone repair. In this review, the beneficial properties of dentin and the ways it interacts with the host bone are described in the context of bone graft materials. Autogenous tooth material has limitations, particularly in terms of the need for tooth extraction and the limited amount available, which currently restrict its use to particular dental procedures. The development of a xenograft dentin-derived material, which retains the properties of autogenous dentin, is described. Such a material could potentially enable the use of dentin-derived material more widely, particularly in orthopedic indications where its properties may be advantageous.

The effect of Vitamin K antagonists as anticoagulants on bleeding in patients post-dental procedures

Background: Individuals undergoing continuous treatment and taking vitamin K antagonist (VKA) and other anticoagulant medications are at a higher risk of experiencing bleeding complications during and after dental surgery procedures. Objective: To determine the effect of vitamin K antagonists in post-dental procedure patients by exploring existing literature on managing patients on vitamin K antagonist therapy as anticoagulants. Methods: This research utilized a literature review based on a database search of studies published between 2019-2024. The literature search used strategies with the terms “Tooth extraction bleeding,” “Odontectomy bleeding,” “Vitamin K Antagonist,” and “Anticoagulant,” utilizing databases such as PubMed, Science Direct, and SCOPUS related to the research topic and meeting eligibility criteria. The studies were then reviewed, summarized, and conclusions were drawn using tables to reveal all data regarding study characteristics and results. Results: Patients using anticoagulants are categorized as high risk for bleeding when undergoing invasive dentistry procedures. VKA is the most commonly used anticoagulant to prevent blood clotting. The consumption of VKA does not significantly affect bleeding post-procedure. Dental procedures can be performed on patients taking anticoagulants without discontinuing the therapy. Conclusion: Based on several studies from various literature sources, it can be concluded that dental procedures in patients taking vitamin K antagonist anticoagulants can still be performed without the risk of bleeding complications with proper local hemostatic measures and perioperative management.

Assessing Tramadol Hydrochloride as an Alternative to Lignocaine Hydrochloride in Dental Implant Procedures: A Randomized Trial.

To evaluate tramadol hydrochloride, an atypical opioid with potential analgesic properties, as a viable alternative to lignocaine hydrochloride in supraperiosteal anesthesia for dental implants. A split-mouth, double-blind, randomized controlled trial was conducted in patients requiring maxillary dental implants. Patients meeting inclusion criteria received either 5% tramadol hydrochloride with adrenaline or 2% lignocaine hydrochloride with adrenaline via supraperiosteal infiltration. Onset, duration of anesthesia, visual analog scale (VAS) pain scores, and adverse effects were recorded. Forty patients were included, with a mean age of 39.35 years, 62.5% male. No significant differences were observed in VAS pain scores between tramadol (2.08 ± 1.328) and lignocaine (2.05 ± 1.260) groups (p = 0.931). Onset of anesthesia showed no significant difference between the tramadol (128.00 ± 18.207 seconds) and lignocaine (128.30 ± 18.287 seconds) groups (p = 0.736). The duration of anesthesia was comparable between tramadol (59 ± 12.092 minutes) and lignocaine (59.90 ± 11.705 minutes) groups (p = 0.0736). Adverse effects included nausea in two tramadol and one lignocaine patient. Tramadol hydrochloride demonstrated comparable local anesthetic efficacy to lignocaine hydrochloride in dental implant surgery Clinical significance: Both drugs provided effective pain control with similar onset and duration of anesthesia. Tramadol may offer an alternative for patients with lignocaine contraindications, although further studies are warranted to validate its safety and efficacy in dental procedures.

Postoperative acute psychological complications following dental procedures under general anesthesia in uncooperative children

BackgroundTo ensure comprehensive dental treatment under general anesthesia(GA) is a viable option, postoperative complications must be minimized. This study investigates the incidence and determinants of acute psychological complications following comprehensive dental treatment under general anesthesia in uncooperative children.Materials and methodsThis study included 71 healthy children aged 5 to 10 years who exhibited uncooperative behavior during dental examinations. All participants received parental consent. Data was collected using a checklist encompassing demographic information, treatment details, physical complications, and psychological complications. The Modified Child Dental Anxiety Scale faces version (MCDASf) questionnaire was administered pre-operatively and five days post-operatively.ResultsThe first day exhibited the most pronounced physical and psychological complications. While the most physical complications had diminished by the fifth day, the psychological effects remained permanent. Tooth extraction was associated with a statistically significant impact on fear of being left alone(P < 0.001), unspecified fear (P = 0.001), nyctophobia (P = 0.001), and excessive crying(P < 0.001).ConclusionPsychological complications persisted for a longer period compared to physical complications. The number of extracted teeth under GA had a significant influence on children’s fear.

Evaluation of Injectate Distribution of the Middle Mental Nerve Block Within the Mandibular Canal in a Cadaveric Canine Model.

Awareness among veterinarians has increased regarding the need for comprehensive pain relief, but many companion animal veterinarians do not administer regional analgesia pre-emptively during dental procedures. The middle mental nerve (MMN) block desensitizes the ipsilateral mandibular incisor and canine teeth as well as soft tissues rostral to the delivery site. There is little published information on the efficacy of the MMN block in dogs. The objective of this study was to determine injectate distribution within the mandibular canal using a radiopaque contrast media/methylene blue solution. Half a milliliter of solution was injected within the opening of the middle mental foramen using a standard hypodermic syringe and a 25G x 25 mm needle. The course of the injectate was traced both via computed tomography (CT) and, in some cadavers, gross dissection. Post-treatment CT revealed that in 90% of the cases, the contrast diffused at least as far caudally as the mesial root of the third premolar tooth. The injectate was not identified within the canal of 5% of cadaveric mandibles examined. Although the solution used diffused caudally within the mandibular canal when injected using recommended clinical techniques, this may not completely represent the extent of clinical effects experienced in live patients. This technique also confirmed that the needle does not need to be advanced into the mandibular canal to achieve adequate diffusion to at least the mesial root of the third premolar tooth.

Cost estimation of preventive dental hygiene care using Time-Driven Activity-Based Costing (TDABC)

Objectives: This study used Time-Driven Activity-Based Costing (TDABC) to measure the value of preventive dental hygiene care and offering a more practical and adaptable cost management method than compared to traditional cost accounting approaches.. Methods: A descriptive survey was conducted using 164 questionnaires collected from dental hygienists actively involved in preventive dental care. The cost data related to labor, materials, and overheads, were anlyzed using detailed classifications of procedures such as scaling, fluoride application, and sealant application. Results: The total allocated cost of 10,163,355 South Korean Won (KRW) was divided by the total working time of the dental clinic (23,520 min), providing a unit cost of 432 KRW/min. Among the three preventive dental care procedures, scaling had the highest total activity cost of 5,867,243 KRW. Conclusions: This study provides valuable evidence for the implementation of an appropriate fee system for preventive dental care performed by dental hygienists. Therefore, this study contributes to the establishment of a fair and rational reimbursement structure.

CLAREAMENTO DENTAL DE CONSULTÓRIO: UMA REVISÃO DE LITERATURA

White teeth are considered ideal for an aesthetic smile. In this way, the search for teeth whitening became the most searched dental procedure for patients. For that, the technique of teeth whitening provides fast results and comfort for the patients. This work treats a narrative literature review that searches to describe techniques of teeth whitening in the clinic, with the bibliographical survey in the following databases BVS, MEDLINE e Google Scholar, in the years of 2014 to 2024. From the selected studies, it was evaluated that the success of the teeth whitening is related to the properties of the whitening agent to infiltrate the dental structure and at the time the substance acts. For this, the most common substances are the hydrogen peroxide and the carbamide peroxide, varying in concentrations according to the technique indicated by the dentist. The clinic's teeth whitening is a procedure safe and efficient and the main disadvantage is the sensibility, which can be treated with the use of methods of desensitizers and laser.

Assessment of parental attitude, knowledge and awareness towards preventive dentistry in south zone of Chhatrapati Sambhajinagar: A questionnaire based cross sectional survey

Introduction: Oral health is a pivotal aspect of overall well-being. In early childhood, primary teeth play a vital role in development of speech, chewing, maintaining proper spacing, and guiding the eruption of permanent teeth. Common oral conditions comprise dental caries, malocclusion, childhood caries, and trauma. Aim: The present study was conducted to assess paternal knowledge towards the forestallment of oral conditions and application of preventive dental procedures in children in South zone of Chhatrapati Sambhajinagar. Materials and Methods: A cross-sectional questionnaire was administered to parents of pediatric patients of age group 3 to12 years in South zone of Chhatrapati Sambhajinagar, Maharashtra, with a sample size of 270 participants. A structured questionnaire, comprising 14 questions in English, was developed, translated and back translated into the local language Marathi by experts to ensure better comprehension by the parents. The questionnaire was divided into two sections: the first focused on demographic information, while the second included 14 multiple-choice, close-ended questions. These questions included topics such as preventive treatments for dental caries, childhood caries, topical fluoride application, fluoridated toothpaste, pit and fissure sealants, habit-breaking dental appliances, malocclusion, mouth guards, and space maintainers. Additionally, the survey addressed harmful habits such as thumb-sucking, tongue-thrusting, and nail-biting. Result: 56.6% of parents sought dental care only after experiencing pain. Additionally, parents of paediatric patients have restricted knowledge about preventive dentistry. Conclusion: Parental knowledge about preventive dental procedures is limited, as is the utilization of these measures.

Comparative evaluation of anxiety levels among adult patients undergoing dental treatment in pediatric and conventional operatory: a randomised clinical trial

Background: Individuals of all ages often experience anxiety before undergoing dental procedures. Therefore, it's crucial for dentists to create a calming operatory environment with distraction techniques to help alleviate adult patient anxiety. This clinical trial evaluated adult patient anxiety in both conventional and pediatric operatory rooms. Methods: This prospective split-mouth randomized controlled clinical trial was 11 conducted between November 2023 and April 2024. Twenty-four adult patients (13 females and 11 12 males) with a mean age of 37±4.53 years participated in this study. Each participant (n=24) received 13 both conventional and pediatric operatory. Pre- and post-operative pulse rates and anxiety scores 14 were measured using a pulse oximeter and modified Corah’s dental anxiety scale, respectively, in both 15 operatory rooms. Results: The study found a statistically significant decrease in both pulse rate and anxiety scores post-operatively in both operatory settings (p&lt;0.05). However, the reduction in anxiety was more pronounced in the pediatric operatory compared to the conventional operatory (p=0.0433). Participants reported greater comfort and reduced anxiety in the pediatric setting, with 83% favoring its vibrant ambiance and 87% feeling less anxious after treatment in this environment. Conclusions: The vibrant environment of a pediatric dentistry operatory, featuring colorful walls, television, music, and other engaging elements can serve as a more effective for reducing anxiety compared to the plain and monotonous ambiance of the operatory.

The Effect of Music Distraction on Dental Anxiety During Invasive Dental Procedures in Children and Adults: A Meta-Analysis.

Background: Dental anxiety and odontophobia are common issues, leading to challenges with oral hygiene and dental health. Music distraction offers an effective and side effect-free solution to alleviate pain and increase the acceptability of dental treatments. Our meta-analysis aimed to assess the efficacy of music distraction in reducing patient anxiety during invasive dental procedures in children and adults. Methods: The PubMed, Web of Science, and Embase databases were searched for clinically controlled trials, using the keywords "music" and "dental anxiety". The main outcome measured was the anxiety score. A meta-analysis was conducted using a random-effects model to estimate the standardized mean differences (SMDs). The subgroup analyses were conducted based on age groups, music preferences, and music styles. The research protocol has been registered with PROSPERO (Registration ID: CRD42022357961). Results: A total of 24 controlled clinical trials involving 1830 participants met the inclusion criteria for the meta-analysis. Music distraction significantly reduced dental anxiety during invasive procedures under local anesthesia (SMD, -0.50; 95% CI, -0.80 to -0.21; p = 0.0009; I2 = 83%). Our subgroup analysis revealed that music distraction was more effective in adults (SMD, -0.51; p = 0.0007) than in children (SMD, -0.47; p = 0.13) in reducing dental anxiety. Regarding music selection, music chosen by the participant (SMD, -1.01; p = 0.008) demonstrated more anxiolytic effects than by the author (SMD, -0.24; p = 0.02). Regarding music styles, classical music (SMD, -0.69; p = 0.009) was associated with better anxiolytic effects in adults. Conclusions: Our meta-analysis supports the use of music to alleviate dental anxiety during invasive procedures. Listening to classical or customized music can serve as an effective adjunct to outpatient surgical care in dental clinics.

Augmented Reality in Dentistry: Enhancing Precision in Clinical Procedures—A Systematic Review

Background: Augmented reality (AR) enhances sensory perception by adding extra information, improving anatomical localization and simplifying treatment views. In dentistry, digital planning on bidimensional screens lacks real-time feedback, leading to potential errors. However, it is not clear if AR can improve the clinical treatment precision. The aim of this research is to evaluate if the use of AR-based instruments could improve dental procedure precision. Methods: This review covered studies from January 2018 to June 2023, focusing on AR in dentistry. The PICO question was “Does AR increase the precision of dental interventions compared to non-AR techniques?”. The systematic review was carried out on electronic databases, including Ovid MEDLINE, PubMed, and the Web of Science, with the following inclusion criteria: studies comparing the variation in the precision of interventions carried out with AR instruments and non-AR techniques. Results: Thirteen studies were included. Conclusions: The results of this systematic review demonstrate that AR enhances the precision of various dental procedures. The authors advise clinicians to use AR-based tools in order to improve the precision of their therapies.

The Role of Ibuprofen and Midazolam in Pediatric Dentistry: A Retrospective Study and Neurophysiological Considerations

Background: Managing anxiety and behavior during pediatric dental procedures is challenging. This study examines the effects of combining ibuprofen with midazolam sedation using both behavioral management and clinical hypnosis to improve patient cooperation and reduce post-treatment pain. Methods: A retrospective cohort study of 311 children (mean age 74.2 months, standard deviation (SD) = 24.7) was conducted. Patients received either midazolam with ibuprofen (n = 156) or midazolam only (n = 155). Behavior was assessed using the Venham Behavior Rating Scale and anxiety with the Dental Subscale of Children’s Fear Survey Schedule (CFSS-DS) and the Inventory of Stressful Situations (ISS) questionnaires. Statistical analyses included Mann–Whitney U tests and correlation analyses. Results: Ibuprofen did not significantly improve behavior during procedures (drinking phase 0.61, SD 1.31, p = 0.13; before treatment 0.25, SD 0.93, p = 0.53, anesthesia 1.21, SD 1.55, p = 0.29; after treatment 0.51, SD 1.22, p = 0.68), indicating that pharmacological pain management alone is insufficient to address behavioral challenges. Ibuprofen significantly reduced post-treatment pain, with 7.2% of cases reporting pain in the non-ibuprofen group compared to none in the ibuprofen group (p &lt; 0.05). Conclusions: Ibuprofen had no effect on intraoperative behavior and only a limited effect on post-procedural pain, mainly for more invasive procedures. This study highlights the integration of sedation with behavioral strategies, such as clinical hypnosis, to manage anxiety and improve patient cooperation, aiming to enhance treatment outcomes using this integrative approach to pediatric dentistry. Further research is needed to optimize these strategies and verify them in a prospective setting.

Risk factors for infectious endocarditis of prosthetic valves: a systematic review

Introduction: valve endocarditis is a major health challenge; its etiology is varied, and it can cause multiple complications or death.Objective: to identify risk factors for infective endocarditis in prosthetic valves. Methods: systematic and retrospective review of the available literature using records from Pubmed, Epistemonikos, Cochrane library, Uptodate.Results: in Argentina, from September 2013 to March 2016, 502 patients with infective endocarditis (IE) were studied in 48 medical centers. The majority were men (69,9 %) with a mean age of 60,7 years. The main risk factors were known underlying heart disease (45,36 %), diabetes (23,5 %), chronic renal failure (16,5 %), neoplastic disease (12,1 %) and history of previous IE (8,96 %). The most frequent predisposing events were endovascular (31,9 %) and dental (12,6 %) procedures. New causes of IE related to gastrointestinal pathologies were also identified.Conclusion: patients with IE have a high clinical risk profile and show increasing age over the decades. Staphylococcus aureus is the most frequent microorganism followed by Streptococcus viridans. The identification of independent predictors of in-hospital mortality continues to be a challenge due to the new agents that are identified or risk factors that are added over time; identifying them could help to establish behavioral modification strategies that lead to improved outcomes

Effect of Dexmedetomidine with or without Midazolam during procedural dental sedation in children: a randomized controlled clinical trial

BackgroundDental anxiety is a global problem in the realm of pediatric dentistry. The use of procedural sedation is recommended to avoid substandard or unsafe dental treatment in preschoolers. This study aimed to compare the effect sedation with Dexmedetomidine with or without Midazolam in terms of sedation level, analgesic effect and ease of treatment completion in preschool children.MethodsA triple blind randomized controlled clinical trial comprised 72 healthy uncooperative children, 4–6 years old, were randomly allocated into three groups of 24 patients each: Group I patients were sedated with nebulized 5 μg/kg Dexmedetomidine (DEX), Group II with nebulized 3 μg/kg DEX followed by nebulized 0.3 mg/kg Midazolam (MID), and Group III with nebulized 0.5 mg/kg MID. Along the session, the three regimens were assessed and compared during the sedation level (children responsiveness) using the Modified Observer’s Assessment of Alertness/Sedation Scale, the analgesic effect using the Face, Leg, Activity, Cry, Consolability scale and ease of treatment completion using a separate 5-point scale. Vital signs were recorded before and during sedation, until full recovery.ResultsA significant difference was detected regarding children responsiveness during operative procedure in favour of DEX in comparison to MID and DEX/MID groups (P = 0.045). Within the DEX group, a significant difference was recorded regarding children responsiveness at optimum sedation and during the operative procedure (P = 0.04). Although, the analgesic effects of sedative drugs showed no statistically significant difference among the study groups (P = 0.20), the ease of treatment completion was statistically higher in the DEX than MID and DEX/MID groups (P = 0.03).ConclusionDexmedetomidine provides a moderate level of sedation, that allowed better patient cooperation, and easy completion of performed dental procedures.

Impact of DBD Plasma Jet Treatment on the Enamel Surface of Primary Teeth.

The impact of cold atmospheric plasma (CAP) treatment on the enamel of twelve primary teeth (incisors, canines, and molars) collected from six children was examined in order to evaluate the possibility of using the CAP technique in dental applications. A radio-frequency dielectric barrier discharge (DBD) plasma jet operating at a voltage of 3.25 kV using a mixture of helium and oxygen as the working gas was used for the generation of plasma as part of the electro-technological method for the treatment of biological material. The plasma exposure time for the primary teeth was 5, 10, and 20 min. The properties of tooth enamel (color, contact angles, surface roughness, surface topography, elemental composition) were examined before (control) and after the plasma treatment. As shown by the results, the plasma treatment time is a key parameter that can induce desired features, such as whitening or improved wettability. However, with prolonged plasma treatment (20 min), the enamel surface may be permanently damaged. The cold-plasma-treated samples were characterized by a higher value of the brightness L* parameter and thus a lighter color, compared to the CAP-untreated teeth. It was also evidenced that the plasma treatment increased the hydrophilicity of tooth surfaces, and the contact angles effectively decreased with the time of the CAP treatment. The tooth surface also became much more heterogeneous and rough with much greater amplitudes in heights. The surface of the primary teeth after the CAP treatment lost its homogeneity, as evidenced by the SEM micrographs. The analysis of the elemental composition revealed only minor changes after the plasma process, which may suggest that the observed morphological changes in the enamel surface are mainly physical and are not a consequence of chemical reactions between the enamel and the reactive components of the cold plasma. Plasma treatment of teeth opens up new possibilities of using this method as an alternative to whitening or pre-treatment before other dental procedures.

Patients’ Perception of using Robotics and Artificial Intelligence in Dentistry: A Cross-sectional Study

Introduction Robotics and Artificial Intelligence (R&amp;AI) are now playing a significant role in influencing the future of dentistry, owing to the fast advancements in technology. The use of AI in dentistry has already begun to enhance patient care and streamline operational efficiency. However, there has been limited research exploring how dental patients perceive the adoption of R&amp;AI. Objective To assess and evaluate the knowledge, concerns, and perceptions of patients agreeing to undergo treatment in its variable forms and procedures under R&amp;AI in order to gain insight into the public understanding of such advanced technologies. Methods This cross-sectional study was conducted at the dental teaching hospital of King Abdul Aziz University in Saudi Arabia from July 2023 to December 2023. The subjects were dental patients from an open network and the public community in different segments, with an alternate group of ages. A digital questionnaire from Google Surveys was used. Data was analyzed using IBM SPSS version 23 (IBM Corp., Armonk, N.Y., USA). Results This study evaluated the perceptions of 807 participants about R&amp;AI dental treatment. The majority, 78.3%, n = 632, reported having already encountered the term AI in dentistry; however, they had never encountered any AI-based treatment (91.9%, n = 742) and remained uninterested in seizing the opportunity (52.8%, n = 381). Around one-third of them also perceived strong disagreement with the dental performance of robotics alone (39.2%, n = 316), even if it was offered at a reduced cost compared to normal treatment (30.7%, n = 248). Conclusion The study's findings reveal that patients' perceptions of R&amp;AI-assisted dental procedures remain inconsistent. While the participants show a greater willingness to embrace the use of R&amp;AI in dental operations, their overall level of trust in R&amp;AI is only mediocre. Patients believe it is critical for a dentist to have control over the R&amp;AI application and take full responsibility for dental care.

Methods: A comprehensive literature search was performed on June 28, 2024, using Web of Science and SCOPUS databases, covering all available publications in selected categories from 2001 to present. Results: PRP use for hair restoration had both the greatest number of total publications among the investigated applications, whereas PRP use in dental procedures had the longest-standing history of publications. PRP use in hair restoration and facial rejuvenation had the greatest number of placebo-controlled and double-blinded randomized controlled trials; however, the impact of results may suffer from a lack of consistency in PRP preparation and outcome measurement between different studies. Conclusion: To effectively validate the utility of PRP across various medical interventions, careful consideration of methodology should be undertaken for future studies to ensure validity of results.

Evaluation of Ventilation Strategies to Mitigate Airborne Infection Risk in a Dental School: A Three-Dimensional CFD Analysis of Airflow Patterns and Ventilation Efficiency

Infection prevention and control is a crucial element in providing a safe environment for dental clinics and reducing airborne infections risks during dental procedures. In response to the prevailing COVID-19 situations, the clinical space in the dental school was operated with ventilation strategies, increasing air exchanges and incorporating supply and return air arrangement based on seating positions. This study evaluated airflow patterns to examine personal exposure to airborne infection risk under these strategies. The three-dimensional computational fluid dynamics technique using computational fluid dynamics (CFD) analysis was performed in 50 multi-units of the dental school of the university in Bangkok, Thailand. The results revealed substantial improvements in indoor ventilation. Improvement of airflow patterns and directions surpassed conventional design of the pre-existing building’s system and helped reduce airborne contaminant concentrations. The further discussion of occupant-based design in dental schools is needed to optimize ventilation systems and engineering controls concerning indoor airborne infections.
