A Traumatic Ulcer Caused by Accidental Lip Biting Following Topical Anesthesia: A Case Report.

Lip biting is a very common issue that dentists encounter, particularly with younger children following a dental procedure. Several studies have reported soft tissue injuries, specifically lip biting following dental treatment under local anesthesia, mostly with an inferior alveolar nerve block. However, such injury with topical anesthesia has never been reported in more than 20 years, and literature has not touched on it much. The next generation of dentists can use this case report as a reference when treating young children. Lip biting can be avoided with risk assessment and the right preventative measures; if it does occur, appropriate palliative care must be given to treat it. This case report presents a case of lip biting by a four-year-old child after undergoing a dental restorative procedure under topical anesthesia.

Comparative Evaluation of Dentinal Defects After Root Canal Preparation Using Various Nickel Titanium Files: An In Vitro Study.

AIM: This study set out to compare the damage done to dentin by three distinct titanium file brands - the Hyflex EDM, the ProTaper Next, and the Waveone Gold Nickel - in order to draw conclusions about which one is the most effective. MATERIALS AND METHODS: Forty-first premolars in the mandible with straight canals and single roots were instrumented using Hyflex EDM, Waveone Gold, and Protaper Next. Dentinal flaws after endodontic treatment were studied by sectioning specimens using a hard tissue microtome and analyzing them under a stereomicroscope. RESULTS: There was no discernible variation between the groups in the coronal third (p=0.312) or apical third (p=0.076). Hyflex EDM and Protaper Next differed significantly in the middle portion of the tape (p=0.016). The Hyflex EDM sample had the fewest cracks. There was no statistically significant difference between Hyflex EDM and Waveone Gold; however, Hyflex EDM had fewer fractures in the middle third of the sample than Waveone Gold did. CONCLUSION: Electric discharge machining (EDM) files made from Hyflex proved to be far superior to their Protaper Next and Waveone Gold counterparts as they induced the fewest cracks in the middle third of the root dentin.

Artificial Intelligence's Use in the Diagnosis of Mouth Ulcers: A Systematic Review.

Artificial intelligence (AI) has been cited as being helpful in the diagnosis of diseases, the prediction of prognoses, and the development of patient-specific therapeutic strategies. AI can help dentists, in particular, when they need to make important judgments quickly. It can eliminate human mistakes in making decisions, resulting in superior and consistent medical treatment while lowering the workload on dentists. The existing studies relevant to the study and application of AI in the diagnosis of various forms of mouth ulcers are reviewed in this work. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards were followed in the preparation of the review. There were no rule violations, with the significant exception of the use of a better search method that led to more accurate findings. Using search terms mainly such as AI, oral health, oral ulcers, oral herpes simplex, oral lichen planus, pemphigus vulgaris, recurrent aphthous ulcer (RAU), oral cancer, premalignant and malignant disorders, etc., a comprehensive search was carried out in the reliable sources of literature, namely PubMed, Scopus, Embase, Web of Science, Ovid, Global Health, and PsycINFO. For all papers, exhaustive searches were done using inclusion criteria as well as exclusion criteria between June 28, 2018, and June 28, 2023. An AI framework for the automatic categorization of oral ulcers from oral clinical photographs was developed by the authors, and it performed satisfactorily. The newly designed AI model works better than the current convolutional neural network image categorization techniques and shows a fair level of precision in the classification of oral ulcers. However, despite being useful for identifying oral ulcers, the suggested technique needs a broader set of data for validation and training purposes before being used in clinical settings. Automated OCSCC identification using a deep learning-based technique is a quick, harmless, affordable, and practical approach to evaluating the effectiveness of cancer treatment. The categorization and identification of RAU lesions through the use of non-intrusive oral pictures using the previously developed ResNet50 and YOLOV algorithms demonstrated better accuracy as well as adequate potential for the future, which could be helpful in clinical practice. Moreover, the most reliable projections for the likelihood of the presence or absence of RAU were made by the optimized neural network. The authors also discovered variables associated with RAU that might be used as input information to build artificial neural networks that anticipate RAU.

Implications of ChatGPT in Public Health Dentistry: A Systematic Review.

An artificial intelligence (AI) program called ChatGPT that generates text in response to typed commands has proven to be highly popular, as evidenced by the fact that OpenAI makes it available online. The goal of the present investigation was to investigate ChatGPT's potential applications as an outstanding instance of large language models (LLMs) in the fields of public dental health schooling, writing for academic use, research in public dental health, and clinical practice in public dental health based on the available data. Importantly, the goals of the current review included locating any drawbacks and issues that might be connected to using ChatGPT in the previously mentioned contexts in healthcare settings. Using search phrases including chatGPT, implications, artificial intelligence (AI), public health dentistry, public health, practice in public health dentistry, education in public health dentistry, academic writing in public health dentistry, etc., a thorough search was carried out on the Pubmed database, the Embase database, the Ovid database, the Global Health database, PsycINFO, and the Web of Science. The dates of publication were not restricted. Systematic searches were carried out for all publications according to inclusion and exclusion criteria between March 31, 2018, and March 31, 2023. Eighty-four papers were obtained through a literature search using search terms. Sixteen similar and duplicate papers were excluded and 68 distinct articles were initially selected. Thirty-three articles were excluded after reviewing abstracts and titles. Thirty-five papers were selected, for which full text was managed. Four extra papers were found manually from references. Thirty-nine articles with full texts were eligible for the study. Eighteen inadequate articles are excluded from the final 21 studies that were finally selected for systemic review. According to previously published studies, ChatGPT has demonstrated its effectiveness in helping scholars with the authoring of scientific research and dental studies. If the right structures are created, ChatGPT can offer suitable responses and more time to concentrate on the phase of experimentation for scientists. Risks include prejudice in the training data, undervaluing human skills, the possibility of fraud in science, as well as legal and reproducibility concerns. It was concluded that practice considering ChatGPT's potential significance, the research's uniqueness, and the premise-the activity of the human brain-remains. While there is no question about the superiority of incorporating ChatGPT into the practice of public health dentistry, it does not, in any way, take the place of a dentist since clinical practice involves more than just making diagnoses; it also involves relating to clinical findings and providing individualized patient care. Even though AI can be useful in a number of ways, a dentist must ultimately make the decision because dentistry is a field that involves several disciplines.

The Efficacy of the Three Types of Plaque Control Methods During Fixed Orthodontic Treatment: A Randomized Controlled Trial.

BACKGROUND: When intraoral orthodontic devices are used, it becomes significantly more difficult to remove plaque effectively. Dentists and orthodontic specialists can come up with more effective preventive strategies while patients are undergoing fixed orthodontic work if they have a deeper understanding of the present scenario. In addition, individuals will become more aware of the importance of good dental hygiene habits as a result of this. OBJECTIVE: To assess and compare the effectiveness of a manual toothbrush, machine-driven toothbrush, and conventional mechanical toothbrush coupled with mouth rinse in removing plaque and maintaining gingival health in patients undergoing fixed orthodontic treatment. METHODS AND MATERIALS: In this research, a total of 222 individuals who met the eligibility and exclusion requirements were randomly selected and offered their written consent. There were a total of 74 participants for each of the three different categories. Category A used a physically driven toothbrush. Category B used a motorized toothbrush. Category C used a physically driven toothbrush together with mouthwash containing 0.2% chlorhexidine gluconate. All study participants were assessed at baseline, one-month follow-up, and two-month follow-up to document the preliminary information, including that of the modified papillary bleeding index (MPBI) by Muhlemann, plaque index (PI) introduced by Silness and Loe, and gingival index (GI) introduced by Loe and Silness. RESULTS: In this study, the mean PI scores at the one-month and two-month follow-ups were minimum in Category C, while it was maximum in Category A at the two-month follow-up. The mean GI scores at the two-month follow-up were minimum in Category C, while it was maximum in Category A at the two-month follow-up. The mean MPBI scores at the two-month follow-up were minimum in Category C, while it was maximum in Category A. It was observed that participants in this trial who only used a typical mechanical brush experienced an increase in PI and GI scores after one and two months of follow-up. At the one-month and two-month follow-ups, it was noted that the values of PI, GI, and MPBI significantly decreased in the study participants using automated toothbrushes as well as in study participants using manual toothbrushes in conjunction with chlorhexidine mouthwash as compared to baseline values. However, when the three categories were compared, it was found that the research participants utilizing both a manual toothbrush and 0.2% chlorhexidine experienced the highest decreases in PI, GI, and MPBI values. CONCLUSION: The reduction in the scores of PI, GI, and MPBI was maximum in orthodontic patients after two months when they apply manual toothbrushing along with 0.2% chlorhexidine.

Evaluation of the Impact of Chlorhexidine Mouth Rinse on the Bond Strength of Polycarbonate Orthodontic Brackets: A Case-Control Study.

BACKGROUND: Shear bond analysis is the procedure used most frequently to gauge the tensile strength of adhesives incorporated in orthodontic treatments. In shear tensile strength analysis, pressure is placed as close as feasible to the interface between the orthodontic bracket and the surface of the tooth, parallel to the long axis of the tooth. Although numerous research on extracted teeth of human and bovine teeth have been conducted, there may still be variables such as pH, humidity, temperature, and others that could affect how these materials behave in the mouth cavity. The impact of chlorhexidine (CHX) on the binding capacity for non-metallic orthodontic brackets in vivo is not well understood. OBJECTIVE: The goal of the current study is to determine how mouth rinses containing 0.12% CHX affect the adhesive strength of polycarbonate orthodontic brackets. METHODS AND MATERIALS: Thirty-four patients were part of the test category, and they were instructed to wash their oral cavity for approximately 30 seconds using 20 ml of 0.12% CHX gluconate (Septodent). Thirty-four patients made up the control category and were instructed to wash their oral cavity for 30 seconds with a placebo mouthwash of a similar hue (20 ml). Both types of mouthwash were administered to the participants by an administrator who was not specifically involved in the trial and were kept in 120 ml labeled plastic bottles. The study participants were also kept unaware of the type of mouthwash. For the mouthwash utilized by study participants, a double-blinding technique was applied. RESULTS: Thirty-four patients were evaluated in the test category. Since the orthodontic bracket broke in two patients, therefore, 32 patients were evaluated in the control category. The mean value of the strength of the shear bond in the experimental category was 15.32 megapascal (Mpa). The SD value was 2.51. The mean value of the strength of the shear bond in the control subgroup was 15.63. On statistical analysis, the t-value was 0.47. The p-value was 0.671. The difference in findings of the strength of the shear bond was statistically non-significant. CONCLUSION: The results of this investigation allow us to draw the conclusion that the shear bond properties of polycarbonate orthodontic brackets are unaffected when treated with 0.12% CHX preceding the binding. The clinically meaningful adhesion strength was likewise attained by the polycarbonate orthodontic brackets.

Artificial intelligence in oral health surveillance among under-served communities.

A sizable percentage of the population in India still does not have easy access to dental facilities. Therefore, it is of interest to document the role of artificial intelligence (AI) in oral surveillance of underserved communities. Available data shows that AI makes it possible to screen, diagnose, track, prioritize, and monitor dental patients remotely via smart devices. As a result, dentists won't have to deal with simple situations that only require standard treatments; freeing them up to focus on more complicated cases. Additionally, this would allow dentists to reach a broader, more underprivileged population in difficult-to-reach places. AI fracture recognition and categorization performance has shown promise in preliminary testing. Methods for detecting aberrations are frequently employed in public health practise and research continues to be focused on them.

Detection of Human PapillomaVirus and its Association with Potentially Malignant Disorders and Oral Squamous Cell Carcinoma: A Retrospective Study.

Aim: This study was carried out with the objective of recognizing the involvement of human papillomavirus (HPV) in conditions of oral squamous cell carcinoma (OSCC) and oral potentially malignant conditions and lesions. Materials and Methods: OSCC samples from thirty patients were collected and thirty paraffin-embedded, oral premalignant specimens were collected. It was decided to use as a negative control samples gingiva from healthy individuals who had no prior history of oral proliferative leukoplakia or OSCC. The samples were then processed using a paraffin-embedded tissue block method. Deoxyribonucleic acid will be extracted from the paraffin-embedded tumor sample of sixty case subjects and tested for the presence of HPV DNA using polymerase chain reaction. Results: In study Group 1, 24 samples were taken from males and 6 from females. In study Group 2, 26 cases were males and 4 were females. In Group 1, 16 cases of moderately differentiated and 14 cases of well differentiated each were present. No case of poorly differentiated were found. There was statistically no significant difference present between male and female when Group 1 and Group 2 was considered. In study Group 1, 0 samples had positive HPV DNA detection, whereas 30 samples had negative HPV DNA detection. In study Group 2, 0 samples had positive HPV DNA detection, whereas 30 samples had negative HPV expression. Conclusion: According to our findings, certain incidences of OSCC may be linked to HPV, however, this was not the case for all of the cancers.

A Cross-Sectional Assessment of Effects of Imprisonment Period on the Oral Health Status of Inmates in Ghaziabad, Delhi National Capital Region, India.

BACKGROUND: Incarcerated individuals usually exhibit high oral health needs than the average population. Several factors contribute to these needs both before incarceration and during the sentence itself. Inmates are a marginalized group, who are at a higher risk for a variety of medical, dental, and emotional disorders than the general population. The aim of the study was to assess of effects of the imprisonment period on the oral health status of inmates. MATERIAL AND METHODS: A total of 532 inmates with imprisonment up to three years, three to six years, and six to ten years were included in the study. Incidence and prevalence of dental caries, decayed, missing, filled teeth (DMFT) index, and periodontal and prosthetic status were evaluated in detail. RESULTS: Results showed that the prevalence of dental caries was relatively high among the convicts. It was found that 98.2% of the inmates had one or more teeth decayed. Additionally, 31.2% (pocket >4mm) of the inmates had poor periodontal status with 4.5% of the subjects having a loss of attachment score of 4-5mm or more. A total of 3.5% of the inmates had full dentures, either upper or lower arch. The relative need for full prosthesis was projected to be around 1.4% of the studied population. CONCLUSION: Within the limitations of the study, the authors found that dental healthcare delivered and received by the inmates is much below the acceptable limit. Additionally, the incidence of dental caries in inmates was unexpectedly higher with tooth decay in 98.2% of subjects. Hence, the need of the hour is to critically incorporate and reinforce our efforts with a special focus on the risk factors of oral health.

A Comparative Study to Evaluate the Anesthetic Efficacy of Buffered Versus Non-buffered 2% Lidocaine During Inferior Alveolar Nerve Block.

BACKGROUND: The study aimed to compare the clinical efficacy, safety, and acceptability of buffered lidocaine (8.4% sodium bicarbonate and 2% lidocaine with 1:80,000 adrenaline) versus non-buffered lidocaine (2% lidocaine with 1:80,000 adrenaline) during inferior alveolar nerve block. MATERIALS AND METHODS: Fifty patients who required bilateral extractions in a single arch were included in this study. One hundred extractions were carried out, and all of the patients had nerve blocks during the procedure. We also took note of the patient's pain level as measured on a visual analog scale, as well as the start of the action, duration of postoperative analgesia, and occurrence of any problems. The duration of anesthesia was assessed by the feeling of numbness and the first sign of pain. RESULT: All the patients in both study groups reported subjective numbness of the lips and tongue. The depth of anesthesia was evaluated by pain and comfort during the procedure with a visual analog scale and showed no significant difference between the two groups. The onset of action for the pterygomandibular nerve block was 1.240.31 minutes (buffered) and 1.710.51 minutes (non-buffered). When compared, the duration of anesthesia was 327.18102.98 minutes (buffered) and 129.0826.85 minutes (non-buffered). CONCLUSION: This study concludes that the buffered solution has a faster onset of action than the non-buffered solution. Both solutions exhibit similar intraoperative efficacy. The duration of postoperative anesthesia was prolonged with buffering. Buffering also reduced pain scores during the early postoperative period.
