BACKGROUND
Dental Unit Water Line (DUWL) deliver water to different handpieces in a dental unit. The water in DUWL circulates in a closed system, where it is taken from a container. The quality of dental water is of considerable importance since patients and dental staff are regularly exposed to water and aerosols generated from dental equipment. Output water from DUWLs may be a potential source of infection for both dental health care personnel and patients.
AIM
To assess the microbial contamination in the DUWL among dental clinics in Chennai.
MATERIALS AND METHODS
An in vitro study was conducted on 60 water samples from 20 dental clinics in Chennai in December 2019. Water samples were collected from three different sources of the Dental unit according to ADA guidelines. The collected samples were assessed for the presence of Aspergillus, Acinetobacter, Pseudomonas aeruginosa, and Legionella by agar plate method. The data were analysed using SPSS software version 20.
RESULTS
Legionella was the most prevalent microorganism with 70% prevalence in a three-way syringe and 50% in scaler and airotor, followed by Pseudomonas aeruginosa and Acinetobacter with 10% prevalence in scaler and airotor and Aspergillus with a prevalence of 10% in the three-way syringe.
CONCLUSION
Most of the dental units were contaminated with Aspergillus, Legionella, Pseudomonas aeruginosa and Acinetobacter which pose a serious threat to the patients as well as the dentists.

A smooth, red, oval, or rhomboid patch on the dorsal midline is the classic presentation of median rhomboid glossitis (MRG), a rare and benign lesion of the tongue. MRG is still not fully understood, which presents diagnostic hurdles and calls for additional clinical investigation. It is frequently associated with candidal infections. We describe a case of a 42-year-old man who initially appeared to have either mechanical irritation or thermal injury related to a painless patch on the dorsum surface of the tongue. We document a case of MRG that was consulted for a standard dental examination in this case report. This article also highlights a dentist's need to identify the lesion and provide appropriate education for the patient.

One of the most crucial tasks of pediatric dentists is to control children's negative behaviors. This study aimed to assess dental behavior and the associated risk factors among children aged 4-12. This cross-sectional study recruited healthy, unaffected children aged 4 to 12 years. Parents were interviewed regarding the sociodemographic details and characteristics of their children's dental visits. Two collaborative dentists examined the children for dental caries (DMFT/DMFT) and behavioral status (Frankl's behavior rating scale). This study included 439 children: 27.3% exhibited uncooperative behavior, and the mean DMFT/dmft was 8.46 ± 3.530. Uncooperative behavior significantly increased when the dental visit was scheduled as an emergency treatment ( = 0.134; Adjusted Odds Ratio (AOR): 1.530) and when there was an elevated DMFT/DMFT ratio ( < 0.001; AOR: 1.308). This study revealed a significant association between children's uncooperative behavior and their first dental visit, emphasizing the need for tailored strategies to address behavioral challenges when scheduling pediatric dental care. The proactive measures included controlling caries and avoiding emergencies.

Review
A scoping review was conducted to synthesize available evidence of knowledge, attitudes, and practices of dental practitioners in providing care to children in out-of-home care (OOHC). Scientific databases and the grey literature were searched: 855 studies were screened after removing duplicates; 800 studies were excluded based on the title and/or abstract, and the full text of 55 studies was reviewed, with 7 included in the analysis. These included three peer-reviewed articles regarding the knowledge, attitudes, and practices of dental practitioners in providing care to children in OOHC, as well as four guidelines. Dental practitioners had some knowledge of the high health care needs of OOHC children, but knowledge regarding when children entering care received dental assessment and about OOHC dental care pathways was low. Practices of dental practitioners were varied, most gave oral hygiene instructions, but there was inconsistency in practices regarding continuity of care following placement changes and failure to attend policies. There was more consensus with dental practitioner attitudes, with practitioners in private settings seeming to prefer not to treat children in OOHC. Three of the identified guidelines provided logistical information about OOHC and consent. The final guideline gave practical information on treating children with a background of adverse childhood events (ACEs), including children in OOHC. Further research and education is warranted to aid dental practitioners in providing care to children in OOHC.

(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.

The internal mechanisms of dental air turbine handpieces (DATHs) have become increasingly intricate over time. To enhance the operational reliability of dental procedures and guarantee patient safety, this study formulated temporal convolution network (TCN) prediction models with the functions of causality in time sequence, transmitting memory, learning, storing, and fast convergence for monitoring the health and diagnosing the rotor and collet failure of DATHs. A handpiece mimicking a dentist's hand load of 100 g was employed to repeatedly mill a glass porcelain block back and forth for cutting. An accelerometer was employed to capture vibration signals during free-running of unrestrained operation of the handpiece, aiming to discern the characteristic features of these vibrations. These data were then utilized to create a diagnostic health classification (DHC) for further developing a TCN, a 1D convolutional neural network (CNN), and long short-term memory (LSTM) prediction models. The three frameworks were used and compared for machine learning to establish DHC prediction models for the DATH. The experimental results indicate that, in terms of DHC predicted for the experimental dataset, the square categorical cross-entropy loss function error of the TCN framework was generally lower than that of the 1D CNN, which did not have a memory framework or the drawback of the vanishing gradient problem. In addition, the TCN framework outperformed the LSTM model, which required a longer history to provide sufficient diagnostic ability. Still, high accuracies were achieved both in the direction of feed-drive milling and in the gravity of the handpiece through vibration signals. In general, the failure classification prediction model could accurately predict the health and failure mode of the dental handpiece before the use of the DATH when an embedded sensor was available. Therefore, this model could prove to be a beneficial tool for predicting the deterioration patterns of real dental handpieces in their remaining useful life.

AIMS
To assess the oral health status and related factors among hearing impaired schoolchildren.
METHODS
A cross-sectional study among 115 hearing impaired schoolchildren enrolled at the School of the Deaf in Jordan. The World Health Organization (WHO) methodology and criteria were applied to collect data on caries, gingival bleeding. The WHO classification modified by Andreasen et al. was used to record traumatic dental injuries (TDIs). Sociodemographic data, oral health practices, and oral health related quality of life information were collected using a structured questionnaire.
RESULTS
The prevalence of caries among the study sample was 84.3%, the dominating component was untreated dental caries. Mean decayed, missing, filled primary teeth (dmft) was 8 in the primary dentition and 3.62 in the mixed dentition, mean Decayed, Missing, Filled permanent Teeth (DMFT) was 1.38 in the mixed dentition and 2.87 in the permanent. The overall mean of gingival bleeding percentage among the whole study sample was 70.38%. the prevalence of TDIs was of 11.3% and mostly caused by falls.
CONCLUSIONS
The prevalence of dental caries and caries experience, rate of gingival bleeding and dental trauma in children with hearing impaired individuals are high compared to figures observed in studies conducted among Jordanian schoolchildren with normal hearing. Dental diseases impact the quality of life of these individuals.

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.
