Assessing the Recordkeeping Quality at the School of Dental Sciences, Universiti Sains Malaysia.

INTRODUCTION:  Dental records are an essential part of dental practice. The quality of dental recordkeeping is paramount in ensuring the delivery of high-quality dental care and is also important for medico-legal reasons. Should there be any dispute or need for review, detailed and well-maintained records can provide evidence of the care provided and the decision-making process. OBJECTIVE: The study aimed to assess the quality of dental recordkeeping and dental charting practice at the dental clinic School of Dental Sciences. METHODS: The study was conducted in a retrospective manner reviewing dental records of patients treated by specialists, dental officers, and postgraduate and undergraduate students at the Hospital Universiti Sains Malaysia over a five-year period. Eight key components of clinical dental records i.e. date of charting, legibility on the odontogram, no blank on the odontogram, whether any mistakes have been strikethrough and initials, medical history, dental history, investigation, and treatment plan were assessed. A modified CRABEL scoring system was used to assess the quality of data retrieved from dental records. RESULTS: The study involved the analysis of 324 case files. Among these, 90 files obtained scores ranging from 60% to 80%, with 7.7% attributed to undergraduates, 9.6% to dental officers, 6.8% to postgraduates, and 3.7% to specialists. The remaining 234 files achieved scores between 80% and 100%, with a breakdown of 17% from undergraduates, 15.4% from dental officers, 18.2% from postgraduates, and 21.3% from specialists. CONCLUSION:  Even though the overall quality of recordkeeping in this study is good, with most records achieving a CRABEL score of 80% and above, it's important to acknowledge that ideally, each component assessed should achieve a perfect score of 100%, as it will reflect the practitioners's work.

Unlocking the Potential: Investigating Dental Practitioners' Willingness to Embrace Artificial Intelligence in Dental Practice.

BACKGROUND: Artificial intelligence (AI) holds significant promise for transforming healthcare delivery, including dentistry. However, the successful integration of AI into dental practice necessitates an understanding of dental professionals' perspectives, attitudes, and readiness to adopt AI technology. This study aimed to explore dental professionals' perceptions, attitudes, and practices regarding AI adoption in dentistry. METHODS: This cross-sectional study was conducted among 256 dental professionals using an online questionnaire. Participants were assessed for familiarity with AI technology, perceived barriers to adoption, attitudes towards AI, current usage patterns, and factors influencing adoption decisions. Data are analysed using descriptive statistics, including frequencies, percentages, means, and standard deviations. Inferential statistics, such as chi-square tests and regression analysis, were employed to examine associations between variables and identify predictors of AI adoption in dentistry. RESULTS: The study surveyed 256 dental professionals from various regions across India, primarily aged 30 to 50 years (mean age: 42.6), with a nearly equal gender split (male: 48.4%, female: 51.6%) and high educational attainment (67.8% with master's or doctoral degrees). Private practices were predominant (56.3%). The diagnostic algorithms and treatment planning software were well known (77.3% and 70.3% familiarity, respectively). Technical concerns (average score: 3.82 ± 0.68) were the main barriers to AI adoption, followed by financial considerations (average score: 3.45 ± 0.72), ethical and legal issues (average score: 3.21 ± 0.65), and organizational factors (average score: 3.67 ± 0.71). Despite these concerns, most participants had positive attitudes towards AI (70.3% agreed). Current usage varied, with diagnostic support and administrative tasks being the most common (44.5% and 82.8% usage, respectively). Perceived utility (average score: 4.12 ± 0.75) and ease of use (average score: 3.98 ± 0.69) significantly influenced adoption, as identified by regression analysis (perceived utility: ß = 0.342, p < 0.001; ease of use: ß = 0.267, p = 0.005). CONCLUSION: This study provides valuable insights into AI adoption in dentistry, highlighting the multifaceted nature of barriers and facilitators that influence dental professionals' adoption decisions. Strategies to promote AI adoption should address practical considerations, ethical concerns, and educational needs to facilitate the integration of AI technology into dental practices.

Assessment of Frontal Sinus Volume and Cranial Base Length Based on Different Vertical Skeletal Patterns: A Cone Beam Computed Tomographic Study.

Introduction Evaluating craniofacial growth is an essential component of orthodontic treatment, and it is assessed by examining the cranial base. The anterior cranial base is regarded as a stable structure, and the frontal sinus is also recognised as a contributing component in the formation of the cranial base. The frontal sinus, a cavity present in the frontal bone, displays variation in both size and shape and has an impact on the overall structure of the skull and face. This study aims to evaluate the impact of vertical skeletal pattern and gender on the volume of the frontal sinus. Materials and methodology In this study, 90 cone beam computed tomography (CBCT) scans from the record's section were included, comprising 46 males (55.44%) and 44 females (48.88%) aged 20 to 35 undergoing orthodontic treatment. The assessment involved evaluating vertical skeletal patterns using a lateral cephalogram derived from the CBCT scans, and volumetric analysis of the frontal sinus was conducted using Dolphin Imaging software (version 11.9; Dolphin Imaging and Management Solutions, Chatsworth, California). Statistical analysis was performed on the collected data using SPSS software, version 20.0 (IBM Corp., Armonk, NY). Pearson correlation, a one-way ANOVA test to determine any statistically significant differences between the means of both frontal sinus volume and cranial base length groups individually and an independent t-test to compare the sample means between the frontal sinus volume and cranial base length groups were performed. Results: A non-significant association was observed between frontal sinus volume and cranial base length in skeletal open bite (p = 0.73) and skeletal deep bite (p = 0.12) between males and females, which implies there is no substantial association between frontal sinus volume (p = 0.08) and cranial base length (p = 0.41) in the different vertical skeletal patterns.  Conclusion: Frontal sinus volume was similar in subjects with a skeletal open bite and a deep bite. Males and females did not show a difference in frontal sinus volume. Hence, it was concluded that frontal sinus volume and anterior cranial base cannot be used as parameters to predict vertical malocclusions.

Conservative Management of Maxillary and Mandibular Fractures in a Pediatric Patient With a Modified Open Cap Splint: A Case Report.

Pediatric maxillofacial fractures, which are not very prevalent, account for around 5% of all face injuries. Children under the age of 13 are more susceptible to craniofacial injuries because they have a larger cerebral mass-to-body ratio than adults. The fracture pattern in children does not resemble that of adults, due to which the treatment of pediatric fractures differs from that of adults and can pose substantial difficulties to the pediatric dentist due to many factors, including the complex anatomy of the developing jaw. In this case report, a 5-year-old male patient presented with an injury to the upper and lower jaw. A case was managed with a conservative approach by using a modified open cap splint. A radiographic investigation, including CT brain and face, was done, which revealed the mandibular symphyseal fracture, bilateral condyle, and right Lefort II fracture. A modified open cap splint was fabricated and fixed with circummandibular and circumzygomatic wiring under general anesthesia. After two months, the fractured site showed good healing on orthopantomography (OPG), and satisfactory occlusion was achieved. The patient was kept on monthly follow-ups for up to five months. Treatment guidelines for pediatric maxillary and mandibular fractures are different from those for adults in that most pediatric cases are managed by a conservative approach. Cap splints are a versatile treatment option for juvenile mandibular fractures because they can be used to restore function and aesthetics with minimal morbidity, do not impede jaw growth or the development of dentition, and can be applied to patients of a wider range of ages.

By assessing visual ergonomics and usability, researchers can develop user-friendly instruments that enhance dental professionals' workflow and efficiency. However, despite its promise, integrating eye tracking in dentistry is not without challenges. Technical limitations, data analysis complexities, and ethical considerations require careful attention to ensure this technology's ethical and responsible use. In conclusion, this narrative review highlights the growing significance of eye-tracking technology in dentistry. Its applications span dental education, clinical practice, and patient care, holding immense potential to revolutionize how dental procedures are conducted, evaluated, and experienced. Nevertheless, further research and collaboration between dental professionals and eye-tracking experts are necessary to unlock the technology's benefits and ensure its seamless integration into dental practices.

Magneto-dynamic tool for full arch immediate loading in post-traumatic restoration with narrow implants: A case report.

New surgical techniques using narrow, tilted implants positioned through a magneto-dynamic tool in guided surgery for a Toronto restoration. A 69-year-old woman wanted fixed rehabilitation to replace her removable complete dentures. A cone-beam computed tomography showed significant bone resorption in both the maxillary and mandibular regions. The plan was to load the entire upper arch with six implants immediately, while removable partial dentures were recommended for the lower jaw. The guided surgery project was aligned with the new dentures, and the laboratory created a printed cast with dental implant analogues in planned positions. A metal-reinforced denture was constructed, and surgery was performed to place six narrow implants using the magneto-dynamic instrument. The denture was directly screwed onto multi-unit abutments. Final rehabilitation was completed after 6 months. Narrow implants can be a good option for fixed, full-arch rehabilitations. Further research is needed to confirm these findings on a larger scale.

A Comparative Assessment of Dental Caries Experience in Relation to Nutritional Status among 6-12-year-old School-going Children and Those with Congenital Heart Disease in Bhubaneswar City.

Aim: To assess the dental caries experience in relation to nutritional status among 6-12- year-old school-going children and those with congenital heart disease in Bhubaneswar city. Materials and methods: A cross-sectional study was conducted among 6-12-year-old healthy school-going children and those with congenital heart disease for a period of 6 months (October 2019-March 2020) in Bhubaneswar, India. Type III clinical examination was carried out as per American Dental Association (ADA) specifications using plane mouth mirrors and community periodontal index (CPI) probes. Clinical oral examination and measurement of the weight and height of the child were performed by a single examiner. Data was analyzed using Statistical Package for the Social Sciences (SPSS) version 21.0. Results: The overall mean decayed missing filled primary teeth surfaces (dmfs) in primary dentition was higher (5.93 ± 10.224) in subjects with congenital heart disease (CHD) (group I) than in healthy controls (3.41 ± 6.192). The overall mean decayed missing filled permanent teeth surfaces (DMFS) in permanent dentition was 0.33 ± 1.105 in subjects with CHD (group I) and 0.24 ± 0.714 in group II. In group I, the majority of them (58.9%) were underweight, followed by 41.1% who were a healthy weight. However, in group II, 47.9% of the study subjects were healthy weight, 26.1% were underweight, 14.4% were obese, and 11.7% were overweight. Conclusion: This study concluded that children with CHD have a higher dental caries experience and poor nutritional status as compared to healthy school-going children.

Microbiological Evaluation of Herbal Extracts against Candida albicans in Early Childhood Caries Patients: An In Vitro Study.

Purpose: The current literature proposes a probable role of Candida albicans (C. albicans) in its etiopathogenesis in early childhood caries (ECC). This study aimed to isolate C. albicans species in children with and without ECC and compare the antifungal efficacy of neem, miswak, cinnamon, clove, stevia, and ketoconazole. This study also aimed to assess and compare salivary pH in children with and without ECC. Materials and methods: A total of 60 children were included in the study, who were divided into two groups-group I (children with ECC) and group II (children without ECC). Plaque samples were collected and streaked on Sabouraud dextrose agar (SDA). C. albicans isolates were evaluated, and their susceptibility to herbal agents was tested and compared. Saliva samples were collected, and salivary pH was tested and compared. Results: The presence of C. albicans was significantly higher in group I (76.7%) as compared to group II (23.3%). The mean zone of inhibition for neem was 4.9 mm, whereas, for miswak, it was 4.5 mm; for cinnamon, 9.3 mm; for clove, 3.8 mm; for stevia, 10.9 mm; and for ketoconazole it was 21.09 mm. The mean salivary pH for group I was 6.7, and that for group II was 7.3. Conclusion: Candida albicans (C. albicans) carriage in children with ECC was significantly higher than in children without ECC. All herbal agents showed significant antifungal activity, with stevia showing the highest activity. The average salivary pH of children without ECC was slightly higher than that of children with ECC.

Evaluation of Less Invasive Sampling Tools for the Diagnosis of Cutaneous Leishmaniasis.

Background: Diagnosis of cutaneous leishmaniasis (CL) usually relies on invasive samples, but it is unclear whether more patient-friendly tools are good alternatives for diverse lesions when used with polymerase chain reaction (PCR). Methods: Patients with suspected CL were enrolled consecutively in a prospective diagnostic accuracy study. We compared dental broach, tape disc, and microbiopsy samples with PCR as index tests, using PCR with skin slit samples as reference test. Subsequently, we constructed a composite reference test including microscopy, the 3 index tests and skin slit PCR, and we compared these same tests with the composite reference test. We assessed diagnostic accuracy parameters with 95% confidence intervals for all comparisons. Results: Among 344 included patients, 282 (82.0%) had CL diagnosed, and 62 (18.0%) CL absence, by skin slit PCR. The sensitivity and specificity by PCR were 89.0% (95% confidence interval, 84.8%-92.1%) and 58.1% (45.7%-69.5%), respectively, for dental broach, 96.1% (93.2%-97.8%) and 27.4% (17.9%-39.6%) for tape disc, and 74.8% (66.3%-81.7%) and 72.7% (51.8%-86.8%) for microbiopsy. Several reference test-negative patients were consistently positive with the index tests. Using the composite reference test, dental broach, and skin slit had similar diagnostic performance. Discussion: Dental broach seems a less invasive but similarly accurate alternative to skin slit for diagnosing CL when using PCR. Tape discs lack specificity and seem unsuitable for CL diagnosis without cutoff. Reference tests for CL are problematic, since using a single reference test is likely to miss true cases, while composite reference tests are often biased and impractical as they require multiple tests.

Oral rehabilitation and associated quality of life following mandibular reconstruction with free fibula flap: a cross-sectional study.

Introduction: Mandibular reconstruction with the free fibula flap (FFF) has become a standardized procedure. The situation is different with oral rehabilitation, so the purpose of this study was to investigate the frequency of implant placement and prosthetic restoration. Additionally, the patients' situation, motivation, and treatment course were structurally assessed. Materials and methods: All cases between January 2013 and December 2018 that underwent mandibular reconstruction in our department with a free fibula flap and gave written informed consent to participate were interviewed with two structured questionnaires about their restoration and quality of life. Additionally, medical records, general information, status of implants and therapy, and metric analyses of the inserted implants were performed. Results: In total 59 patients were enrolled and analyzed in this monocentric study. Overall, oral rehabilitation was achieved in 23.7% at the time of investigation. In detail, implants were inserted in 37.3% of patients and showed an 83.3% survival of dental implants. Of these implanted patients, dental implants were successfully restored with a prosthetic restoration in 63.6. Within this subgroup, satisfaction with the postoperative aesthetic and functional result was 79.9% and with the oral rehabilitation process was 68.2%. Satisfaction with the implant-borne prosthesis was 87.5%, with non-oral-squamous-cell-carcinoma patients being statistically significantly more content with the handling (p=0.046) and care (p=0.031) of the prosthesis. Discussion: Despite the well-reconstructed bony structures, there is a need to increase the effort of achieving oral rehabilitation, especially looking at the patient's persistent motivation for the procedure.

Monowave vs. Polywave Light - Curing Units: Effect on Light Transmission of Composite without Alternative Photoinitiators.

Objective: The aim of this study was to compare the light transmission of monowave and polywave-curing devices by a bulk-fill composite containing only camphorquinone as a photoinitiator. Materials and methods: Three light-curing devices were used to cure bulk-fill composite QuiXfil: one monowave (Translux® Wave) and two polywave (VALO Cordless and Bluephase® PowerCure. The NIST-calibrated spectrometer (MARC Resin Calibrator, BlueLight Analytics Inc.) was used to measure the incident and transmitted light through a 2-mm composite specimen over 20 s. Light transmittance was calculated from the ratio of the amount of transmitted and incident light. For data analysis (ANOVA, α = 0.05), total irradiation of the entire spectrum, irradiation with wavelengths of 360-420 nm for the violet spectrum, and 420-540 nm for the blue spectrum were selected. Results: Monowave curing unit Translux® Wave had the lowest light transmission (13.78 ± 0.5%), similar to the violet light transmission of polywave devices (12.02 ± 0.94% and 13.81 ± 1.72% for Valo Cordless and Bluephase PowerCure, respectively). Blue light transmittance (32.15-23.70%) was more than twofold higher than for the wavelengths in the violet region of the spectrum (13.81-12.02%) for the two polywave devices. VALO Cordless showed the highest total and blue light transmission (p<0.001). There was no significant difference in the transmission of the violet part of the spectrum between VALO Cordless and Bluephase® PowerCure (p = 0.465). Conclusion: Within the limitations of this study, we could conclude that polywave curing devices can be used for the polymerization of the bulk-fill composite with camphorquinone as the sole photoinitiator.

The Effects of Grape Seed Oligomeric Proanthocyanidin and Nisin on Dental Pulp Stem Cells.

Objective: This study aimed to evaluate the biological effects of "proanthocyanidin" (PA), and "nisin" (Ni), on dental pulp stem cells (DPSCs) and LPS-induced DPSCs as well as their antimicrobial effects against S. aureus and E. coli. Materials and methods: After characterization of DPSCs, cytotoxicity of PA and Ni on DPSCs were evaluated using a water-soluble tetrazolium salt (WST-1). The cytokines and chemokines released by DPSCs and the expression levels of IL-6, IL-8, and TNF alpha were detected with human Cytokine Array C5 and enzyme-linked immunosorbent assay (ELISA), respectively. The antibacterial activities of PA and Ni were tested using the drop plate method. Results: PA at 75 µg/ml increased cell viability, decreased TNF-α expression of DPSCs, did not show any cytotoxic effects on LPS-induced DPSCs, and also showed a tendency to decrease TNF-α expression. PA at 75 µg/ml exhibited higher expressions of TIMP-2, OPG, IL-7, and IL-8 in LPS-induced DPSCs compared to DPSCs. Ni at 100 µg/ml decreased TNF-α expression in DPSCs with no cytotoxic effects. It provided increased cell viability and a downregulation trend of TNF-α expression in LPS-induced DPSCs. Both Ni and PA provided strong antibacterial effects against S. aureus. Ni at 200µg/ml had strong antibacterial effects against E. coli without affecting negatively the viability of both DPSCs and LPS-induced DPSCs and showed anti-inflammatory activity by decreasing TNF-α expression. PA provided strong antibacterial effects against E. coli at 200 µg/ml but affected DPSCs viability negatively. Conclusion: PA and Ni at specific concentrations exhibited immunomodulatory activity on DPSCs and LPS-induced DPSCs without any cytotoxic effects and strong antibacterial effects on S. aureus.

Comparison of Three Different Orthodontic Adhesives Bonded to Metallic and Ceramic Brackets: SEM and SEM/EDX Analysis (In Vitro Study).

Objectives: To compare three different orthodontic adhesives (Transbond XT Light Cure Adhesive, Heliosit Orthodontic, Fuji Ortho LC) bonded to two types of orthodontic brackets: ceramic brackets (Fascination Roth 0.22) and metallic brackets (Topic Roth 0.22, Dentaurum). Materials and methods: The study was performed on 18 human teeth (6 for each adhesive). The prepared teeth were divided into three groups according to the examination time. Subsequently, they were observed after 1, 2 and 3 weeks following bonding. After the experimental procedure, the teeth samples were cut in half along the longitudinal axis in the vestibulo-oral direction, fixed with conductive carbon cement, placed in a high-vacuum evaporator and then coated with carbon. One half of each sample was observed under a Field-emission gun scanning electron microscope (FEG-SEM Hitachi SU 8030, Japan), while on the second half of the samples qualitative (X-ray line-scans) and semi-quantitative point X-ray energy dispersive analyses (EDX) were performed with Thermo Noran (USA) NSS System 7, equipped with Ultra Dry detector (30 mm2 window). Results: Transbond XT had an ideal bond with the enamel and the bracket base, with rare presence of microgaps and cracks in the enamel. Heliosit Orthodontic demonstrated a better bond relationship with the bracket base than the enamel, whereas in the latter the presence of microgaps in the bond was observed. The microphotographs of Fuji Ortho LC demonstrated many cracks inside the adhesive, and some of them continued to move forward into the enamel surface. Therefore, an impression of a very solid bond relationship with the enamel exists, with cracks being present in the enamel surface and never at the enamel-adhesive interface. Microgaps also appeared at the bracket-adhesive interface. Conclusion: Transbond XT is a highly filled composite resin and is an ideal orthodontic adhesive in each aspect examined, with an ideal enamel-adhesive and bracket-adhesive interface. Heliosit Orthodontic provides better bracket-adhesive interface compared to the enamel. Fuji Ortho LC as a solid resin-modified GIC provides a better enamel-adhesive interface, compared to the bracket base.

Early Childhood Oral Health Impact Scale: Psychometric Evaluation in Portuguese Preschoolers.

Objective: to contribute to the validation of the Early Childhood Oral Impact Scale (ECOHIS) by studying its psychometric properties when applied to a Portuguese preschool population. Methods: Cross-sectional study conducted with children aged between three and five-years-old. The non-probabilistic sample included two preschools in the municipality of Lisbon. Children who agreed to participate and whose guardians signed the informed consent were included. Data collection included a questionnaire, administered to the parents, and an intraoral examination of the children. The questionnaire included the Portuguese version of ECOHIS. The intraoral examination included the caries diagnosis according to the World Health Organization criteria. Discriminant validity compared the ECOHIS score between children with and without caries experience (Mann-Whitney U-test). Cohen's d was calculated to estimate the magnitude of the difference. Reliability analysis included Cronbach's α and test-retest. Construct validity was analyzed by the correlation between the ECOHIS score and dmft (Spearman's correlation). A significance level of 5% was used. Results: The sample included 104 children (mean age 4.1 years). ECOHIS values were significantly different between children with and without caries (p=0.004). The Cohen's d was 0.84. The Cronbach's was 0.78, with no significant increase in value when eliminating any of the items. The test-retest showed significant correlation (r=0.76; p=0.01). There was a significant correlation between the ECOHIS score and caries experience (r=0.28; p=0.004). Conclusion: The Portuguese version of the ECOHIS showed good psychometric properties, indicating that it is a reliable and valid tool to measure the impact of oral health in preschool children.

Occlusal Radiographs in a Turkish Pediatric Subpopulation.

Objectives: Dental radiographs are a useful diagnostic aid in the oral health care and dental treatment of children. The most commonly used radiographs are periapical and panoramic radiographs. Occlusal radiographs are preferred in more specific cases. The aim of this study was to retrospectively evaluate the reasons for obtaining occlusal radiographs in pediatric patients. Material and methods: Occlusal radiographs of patients aged 1-13 years who attended the Pediatric Dentistry Clinic of Ondokuz Mayis University Faculty of Dentistry between 01 August 2015 and 01 August 2020 were retrospectively evaluated. Patients with syndromes and diseases that could cause cleft lip and palate and dental anomalies were not included in the study. The medical history of the 354 patients who were included in the study was provided by the automated system. Results: A total of 359 occlusal radiographs from these patients were analysed. The number of male patients included in the study was 208 and the number of female patients was 146. Occlusal radiographs of the maxilla of 312 patients were taken, of the mandible of 37 patients, and both the upper and lower jaws of 5 patients. It was found that occlusal radiographs were taken mostly for dental trauma in the permanent dentition (156), injuries in the primary dentition (68) and for the diagnosis of dental anomalies (57). Conclusions: Occlusal radiographs are taken for specific situations in pediatric dentistry and are particularly useful in the detection and diagnosis of primary and permanent tooth injuries.

Challenges and Solutions in Clinical Workflow for the Rehabilitation of Completely Edentulous Patients Through CAD/CAM Dentures: A Case Study.

In the field of removable prosthodontics, computer-aided design and computer-aided manufacturing (CAD/CAM) have become widely recognized. The traditional method, which uses heat-polymerized resins for injection or compression molding, necessitates up to five patient visits and laborious laboratory processes. A digital workflow combined with a CAD/CAM methodology can provide prompt prosthesis delivery for patients with time constraints. This article's goal is to outline the steps and the limitations in the fabrication of digital dentures as well as the challenges, limitations, and solutions developed while developing a clinical workflow for the rehabilitation of completely edentulous patients with the CAD/CAM System.

Prospective Evaluation of Dental Practitioners' Knowledge, Attitude, and Practice Toward Adult Dental Pain Management: A Cross-Sectional Multicenter Study.

Background Dental pain among adults is a prevalent concern impacting oral health and quality of life. Dental pain management presents a significant challenge for dental practitioners in effectively alleviating patient discomfort. Among the medications available, non-steroidal anti-inflammatory drugs (NSAIDs) are considered the most effective analgesics in dental care. While numerous studies have been conducted to assess the role of antibiotics in dental practice, there is a scarcity of studies specifically examining the prescription patterns of analgesics. The primary aim of this study was to evaluate the knowledge, attitudes, and practices of dental practitioners (DPs) in India concerning the management of adult dental pain. Method This survey utilized a computer-aided questionnaire-based approach. A total of 110 dentists, including 16 from metropolitan areas and 84 from non-metropolitan cities practicing at dental healthcare setups, clinics, and hospitals, were interviewed as part of the survey. The participants comprised dental professionals specializing in prosthodontics, endodontics, orthodontics, periodontics, oral surgery, pedodontics, and oral medicine. The study was conducted between September 2022 and January 2023. Results The primary reason patients seek dental consultation, as reported by 95% of dentists, is tooth cavities, followed by tooth sensitivity, post-root canal treatment, and pulpitis. All surveyed dentists prescribed NSAIDs to their patients for managing dental pain. Local anesthesia (LA) was the second choice for 75% of dentists, prescribed to 23% of their patients. The primary use of NSAIDs was for patients experiencing severe pain and to manage post-procedure pain. Eighty percent of DPs recognized ketorolac as a fast-acting molecule, providing immediate relief within 10-15 minutes. Overall, analysis indicated that 98% of DPs are satisfied and 67% are extremely satisfied with ketorolac among monotherapies for dental pain management due to its quick onset of action, fast pain relief, and usefulness in post-surgical pain management. Conclusion NSAIDs like ketorolac, diclofenac, and aceclofenac were the preferred prescriptions for overall dental pain management. Dental practitioners associated ketorolac with fast pain relief, quick onset of action, and effectiveness in post-surgical pain management, emphasizing its lasting effects. The insights from the study contribute to enhancing dental pain management strategies.

How to make full use of dental pulp stem cells: an optimized cell culture method based on explant technology.

Introduction: Dental pulp stem cells from humans possess self-renewal and versatile differentiation abilities. These cells, known as DPSC, are promising for tissue engineering due to their outstanding biological characteristics and ease of access without significant donor site trauma. Existing methods for isolating DPSC mainly include enzyme digestion and explant techniques. Compared with the enzymatic digestion technique, the outgrowth method is less prone to cell damage and loss during the operation, which is essential for DPSC with fewer tissue sources. Methods: In order to maximize the amount of stem cells harvested while reducing the cost of DPSC culture, the feasibility of the optimized explant technique was evaluated in this experiment. Cell morphology, minimum cell emergence time, the total amount of cells harvested, cell survival, and proliferative and differentiation capacity of DPSC obtained with different numbers of explant attachments (A1-A5) were evaluated. Results: There was a reduction in the survival rate of the cells in groups A2-A5, and the amount of harvested DPSC decreased in A3-A5 groups, but the DPSC harvested in groups A1-A4 had similar proliferative and differentiation abilities. However, starting from group A5, the survival rate, proliferation and differentiation ability of DPSC decreased significantly, and the adipogenic trend of the cells became more apparent, indicating that the cells had begun to enter the senescence state. Discussion: The results of our study demonstrated that the DPSC obtained by the optimized explant method up to 4 times had reliable biological properties and is available for tissue engineering.

Associations of Serum Vitamin D With Dental Caries and Periodontitis: The HUNT Study.

OBJECTIVE: To study the relationships of serum 25-hydroxyvitamin D [25(OH)D] with dental caries and periodontitis in a general Norwegian adult population. METHODS: We analysed a subsample of 1605 participants from the Trøndelag Health Study (HUNT) in Norway that had serum 25(OH)D) levels measured in HUNT3 (2006-08) and oral health assessed in the HUNT4 Oral Health Study (2017-19). Negative binomial and Poisson regression models were used to estimate the ratios of means (RMs; for count oral outcomes) and prevalence ratios (PRs; for dichotomous oral outcomes). RESULTS: Serum 25(OH)D was inversely associated with the number of decayed teeth in a dose-response gradient (<30.0 nmol/L: RM 1.41, 95% CI 1.07-1.85; 30.0-49.9 nmol/L: 1.14, 0.98-1.32 and ≥75.0 nmol/L: 0.84, 0.67-1.04, as compared to the 50.0-74.9 nmol/L group, P for trend <.001). Each 25 nmol/L decrease in 25(OH)D level was associated with a 15% (RM 1.15, 95% CI 1.05-1.26) increase in the mean number of decayed teeth. Serum 25(OH)D <30.0 nmol/L was associated with a 35% higher prevalence of severe periodontitis (PR 1.35, 95% CI 1.00-1.83). No association was observed between 25(OH)D and the number of natural teeth. CONCLUSION: The present study suggested that serum 25(OH)D level had an inverse and dose-response association with the number of decayed teeth, and serum 25(OH)D <30 nmol/L was associated with a higher prevalence of severe periodontitis in this Norwegian adult population.

Tooth whitening: current status and prospects.

As a safe, effective, economical, and convenient technique, tooth whitening is one of the most popular treatments for improving tooth discoloration. This review summarizes the theoretical and recent research developments in the classification and mechanisms of tooth discoloration, as well as the principles, agents, effects, and side effects of tooth whitening techniques. The aim is to provide a basis for the clinical treatment of tooth whitening techniques and to suggest possible new ideas for further research. The accepted mechanism of whitening is the redox reaction of oxides in the whitening reagent, and the whitening effect is remarkable. However, side effects such as tooth sensitivity and irritation of gum and other oral soft tissues can still occur. It is recommended that more monitoring be carried out in the clinic to monitor these side effects, and care should be taken to protect the soft tissues in the mouth during office whitening procedures. Furthermore, there is a need to develop new additives or natural whitening products to reduce the occurrence of side effects.
