BACKGROUND
Orthodontic treatment often spans several months or even years, which can be burdensome for patients. Biomodulation techniques have emerged as potential strategies to expedite orthodontic tooth movement.
MATERIALS AND METHODS
A randomized clinical trial was conducted with a sample of 60 orthodontic patients, aged 12-30 years, requiring fixed appliance therapy. Patients were randomly assigned to either the biomodulation group ( = 30) or the control group ( = 30). The biomodulation group received low-level laser therapy (LLLT) along with traditional orthodontic treatment, while the control group received conventional orthodontic treatment without LLLT. Treatment duration, pain perception, and orthodontic tooth movement were assessed during the study period.
RESULTS
The results demonstrated a significant reduction in treatment duration in the biomodulation group compared to the control group. The biomodulation group exhibited a 30% reduction in overall treatment time, with an average treatment duration of 8.4 months, while the control group required an average of 12 months ( < 0.001). Pain perception during orthodontic adjustments was lower in the biomodulation group. Additionally, biomodulation was associated with a statistically significant increase in the rate of tooth movement, as evidenced by a 20% reduction in the time required to achieve desired tooth alignment ( < 0.01).
CONCLUSION
Biomodulation through low-level laser therapy represents a promising adjunct to traditional orthodontic treatment, significantly accelerating tooth movement and reducing treatment duration.

AIM
The current study was conducted with the aim of evaluating the retention protocol followed by orthodontists in India.
MATERIAL AND METHODS
A cross-sectional web-based questionnaire survey was carried out to evaluate the retention protocol. To determine the sample size, a pilot study was carried out, and the final sample arrived was 250 subjects. The current study's inclusion criteria took into account those who had finished their BDS&MDS (Orthodontist).
RESULTS
The data were statistically examined when the surveys were received and completed. The choice for fixed retainers was 67.4%. Retainer wear time preferences ranged widely, with 60% preferring 12-18 hours. The initial post-retention check appointment was planned by the majority of orthodontists (47.6%) within the next three months. Recall appointments for retention checks were only planned by the majority of orthodontists (56.3%) once every three months. Regular involvement by patients at their retention check appointments was (38%).
CONCLUSION
The most commonly used and preferred type of retainer is fixed retainer, and dentist preferences range around 12-18 hours of wear time. Furthermore, the duration of the retainer wear preferred by most orthodontists/dentists is 10 months to 2 years.

To compare the effectiveness of various modes of oral health education in visually impaired children. A total of 100 students aged 8-15 years were included. The children were divided randomly into four groups. Children in Group I received oral hygiene instructions through Braille pamphlets. In Group II, children received instructions through nonvisual desktop access (NVDA). For children in Group III, both Braille and NVDA were used to deliver the instructions. Children included in Group IV served as controls, who did not receive any information in any form for the study period. After oral examination to record plaque and OHI-S scores, a questionnaire was given to the children to assess their knowledge scores. The same questionnaire was repeated after 1 month to reassess the knowledge score in different groups. Chi-square test, Wilcoxon test, and analysis tests were used. The mean plaque scores among the control group children at the follow-up were significantly higher (2.5 ± 0.64) than any other group. Similarly, the control group had higher mean oral hygiene simplified scores (1.75 ± 1.32) than the Braille (1.12 ± 0.65), NVDA (0.85 ± 1.38), and Braille + NVDA (0.2 ± 0.64) groups at follow-up. With regards to the mean total knowledge score, the control group scored the least (2.16 ± 1.46), while the Braille, NVDA, and Braille + NVDA groups scored 3.16 ± 1.43, 4.52 ± 1.12, and 6.36 ± 0.52, respectively. Combination of Braille and NVDA was found to be effective in educating and motivating visually impaired children regarding maintenance of oral hygiene.

BACKGROUND
Preterm birth is a heterogeneous condition with multiple underlying causes, and periodontal diseases are one of them. Approximately 900000 preterm births are reported in Pakistan each year. Oral infections such as periodontitis during pregnancy are associated with adverse pregnancy outcomes such as low birth weight and preterm births. However, different studies have reported contradictory findings. We conducted a cross-sectional study to assess the association of preterm birth with oral infection in pregnancy.
METHODS
We conducted a cross-sectional analytical study on 400 postpartum pregnant women in Khyber Teaching Hospital, Peshawar. Only women within the age bracket of 18‒40 years were recruited. Data were collected by an interview-based structured questionnaire. The extent and severity index were used to assess the periodontal health of participants. Frequency tables were generated, and the chi-squared test was used to determine associations between different categorical variables.
RESULTS
The mean age of the participants was 25.8±4.9 years. Approximately 87.5% of the women had generalized periodontitis. Approximately 68% of mothers had moderate severity of periodontitis. The extent index showed no notable difference between the preterm and full-term birth groups. In contrast, the severity index displayed a statistically significant difference between the preterm and full-term birth groups.
CONCLUSION
The majority of women had generalized periodontitis. The severity index demonstrated a significant association between maternal periodontitis and preterm births. There was no association between the age of mothers and preterm births. Complications in pregnancy were not associated with preterm births.

OBJECTIVE
This study aimed to assess undergraduate dental students' communication skills in relation to patient sociodemographic factors using a three-perspective approach; the student, the patient, and the clinical instructor perspective.
MATERIALS AND METHODS
A cross-sectional study was conducted using validated modified-communication tools; Patient Communication Assessment Instruments (PCAI), Student Communication Assessment Instruments (SCAI), and Clinical Communication Assessment Instruments (CCAI). Moreover, 176 undergraduate clinical year students were recruited in this study whereby each student was assessed by a clinical instructor, a patient, and self-evaluation.
RESULTS
The clinical communication skills domains were not significantly influenced by patient sociodemographic factors, including sex, educational background, and the number of visits (p > .05). However, this study revealed a statistically significant difference in the domain of "caring and respectful" of the SCAI between the low- and middle-income groups.
CONCLUSIONS
Overall, most of the patient sociodemographic factors did not affect clinical communication skills. However, patient income groups played a significant role in one of the communication domains.

BACKGROUND
Minimizing muscle strain and reducing the risk of musculoskeletal disorders associated with intraoral scanner (IOS) usage require ergonomic awareness, device selection, and workplace adjustments in dental practice. This preliminary clinical study aimed to simulate intraoral scanning tasks using wired and wireless IOSs and assess muscle activation and fatigue for both types.
MATERIALS AND METHODS
Fourteen participants performed intraoral scanning tasks using wired and wireless IOSs (i700; MEDIT), with weights of 280 g and 328 g, respectively. The same computer system and software conditions were maintained for both groups (N = 14 per IOS group). Electrodes were placed on arm, neck, and shoulder muscles, and maximal voluntary contraction (MVC) was measured. Surface electromyography (EMG) was performed during the simulation, and EMG values were normalized using MVC. The root mean square EMG (%MVC) and muscle fatigue (%) values were calculated. Statistical comparisons were performed using the Mann-Whitney U and Friedman tests, with the Bonferroni adjustment for multiple comparisons (α = 0.05).
RESULTS
Arm (flexor digitorum superficialis) and neck muscles (left sternocleidomastoid and left splenius capitis) showed significantly higher EMG values with wireless IOS (P < 0.05). The neck (left sternocleidomastoid and right levator scapulae) and shoulder muscles (right trapezius descendens) demonstrated significantly higher muscle fatigue with wireless IOS (P < 0.05).
CONCLUSIONS
The consecutive use of heavier wireless IOS may increase the risk of muscle activation and fatigue in certain muscles, which may have clinical implications for dentists in terms of ergonomics and musculoskeletal health.

OBJECTIVES
Segmentation of anatomical structures on dento-maxillo-facial (DMF) computed tomography (CT) or cone beam computed tomography (CBCT) scans is increasingly needed in digital dentistry. The main aim of this research was to propose and evaluate a novel open source tool called DentalSegmentator for fully automatic segmentation of five anatomical structures on DMF CT and CBCT scans: maxilla/upper skull, mandible, upper teeth, lower teeth, and the mandibular canal.
METHODS
A retrospective sample of 470 CT and CBCT scans was used as a training/validation set. The performance and generalizability of the tool was evaluated by comparing segmentations provided by experts and automatic segmentations in two hold-out test datasets: an internal dataset of 133 CT and CBCT scans acquired before orthognathic surgery and an external dataset of 123 CBCT scans randomly sampled from routine examinations in 5 institutions.
RESULTS
The mean overall results in the internal test dataset (n = 133) were a Dice similarity coefficient (DSC) of 92.2 ± 6.3 % and a normalised surface distance (NSD) of 98.2 ± 2.2 %. The mean overall results on the external test dataset (n = 123) were a DSC of 94.2 ± 7.4 % and a NSD of 98.4 ± 3.6 %.
CONCLUSIONS
The results obtained from this highly diverse dataset demonstrate that this tool can provide fully automatic and robust multiclass segmentation for DMF CT and CBCT scans. To encourage the clinical deployment of DentalSegmentator, the pre-trained nnU-Net model has been made publicly available along with an extension for the 3D Slicer software.
CLINICAL SIGNIFICANCE
DentalSegmentator open source 3D Slicer extension provides a free, robust, and easy-to-use approach to obtaining patient-specific three-dimensional models from CT and CBCT scans. These models serve various purposes in a digital dentistry workflow, such as visualization, treatment planning, intervention, and follow-up.

Introduction Dental caries is a worldwide disease affecting children and older populations. There are multiple interventions to treat dental caries that could be sometimes hard to deliver, due to the general status of patients such as insufficient cooperation or medically compromising conditions. Therefore, another alternative to control dental caries is being used and has been recently introduced and approved by the Saudi FDA which is silver diamine fluoride (SDF). Objectives This study aimed to investigate the level of knowledge, attitudes, and practices about the use of SDF among dentists in Riyadh, Saudi Arabia. Materials and methods This cross-sectional study was conducted using pretested, an online digitally designed questionnaire sent to 500 Saudi Commission for Health Specialties (SCFHS) registered dentists working in the following specialties: general practitioners, interns, restorative, family, pediatric, and public health dentists who are working in public and private hospitals and clinics. One-way ANOVA was used to determine the comparison of participants' knowledge and Practice with three variables (participants' specialty, place of work, and years of experience), while Chi-square was used for the comparison of respondent's attitudes about the use of SDF and the above same variables. Result A total of 265 responses were received (response rate is 53%). The majority of the respondents were general practitioners and interns 144 (54.3%). Over 50% of dentists believed that they were very informed about SDF. The mean score of knowledge and practices of SDF of participants was found below average 49.13 (19.81) and 43 (26.12), respectively. Correlation of the mean score knowledge and practicing SDF with the type of specialty showed that pediatric dentists had statically significant (P<0.05) higher mean of knowledge 66.94 (SD=17.64) and practicing of SDF 61.93 (22.12) as compared to other specialties, while no statistically significant differences were found among the groups in the overall knowledge and practices based on years of experience and workplace. Attitudes were correlated with the three above variables (specialty, years of experience, and place of work) and showed that pediatric dentists had the highest satisfaction with the results of SDF (85.3%) and were more willing to recommend using it to others (91.2%) as compared to the other groups(P<0.05). No statistically significant differences were found with respect to the later variables. Conclusion The findings of this study showed that irrespective of the positive attitude of participants towards SDF, pediatric dentists were found to have higher knowledge and use SDF more than other dentists in different specialties. Furthermore, they showed higher satisfaction with its use. Years of experience and workplace had no effect on the level of knowledge or practice among participants.

Oral health is high on the global agenda following the adoption of the 2022 global strategy on oral health at the 75th World Health Assembly. Given the global burden of oral disease, workforce development to achieve universal health coverage [UHC] is crucial to respond to population needs within the non-communicable disease agenda. The aim of this paper is to present an overview of the oral health workforce [OHWF] globally in relation to key contextual factors. Data from the National Health Workforce Accounts and a survey of World Health Organization [WHO] member states were integrated for analysis, together with country-level data on population and income status. Data are presented using the WHO categorisation of global regions and income status categories established by the World Bank. Workforce densities for key OHWF categories were examined. Multiple regression was used to model workforce density and contextual influences. Challenges and possible solutions were examined by country income status. There are approximately 3.30 dentists per 10,000 population globally, and a combined OHWF [dentists, dental assistants/therapists and dental prosthetic technicians] of 5.31 per 10,000. Marked regional inequalities are evident, most notably between WHO European and African regions; yet both make greater use of skill mix than other regions. When adjusted by region, 'country income status' and 'population urbanization' are strong predictors of the workforce density of dentists and even more so for the combined OHWF. Maldistribution of the workforce [urban/rural] was considered a particular workforce challenge globally and especially for lower-income countries. Strengthening oral health policy was considered most important for the future. The global distribution of dentists, and the OHWF generally, is inequitable, with variable and limited use of skill mix. Creative workforce development is required to achieve the global oral health agenda and work towards equity using innovative models of care, supported by effective governance and integrated policies.

INTRODUCTION
Stress and burnout rank among the foremost dentistry-related concerns. Understanding stress and burnout among Palestinian dentists is crucial for developing targeted interventions and support systems. The study aimed to assess stress levels among dentists in Palestine, identify factors contributing to stress, and determine the relationship between stress and burnout in this professional group.
METHOD
ology: A cross-sectional study was conducted, employing a self-administered questionnaire to gather data from 271 dentists from March to June 2023. The Maslach burnout inventory was utilized to measure burnout across emotional exhaustion, depersonalization, and reduced personal accomplishment dimensions, while the 10-item perceived stress scale was employed to measure stress levels.
RESULTS
The findings revealed that 81% of Palestinian dentists reported experiencing moderate to high levels of stress. Emotional exhaustion was a prominent aspect of burnout, with 48% of participants reporting high levels. The multivariate linear regression analysis demonstrated a significant association between stress scores and female participants (p = 0.001), daily sleeping hours (p = 0.016), as well as emotional exhaustion and personal accomplishment burnout subscales (p ≤ 0.001 for both).
CONCLUSION
The study revealed high-stress levels among Palestinian dentists, which were associated with sex and daily sleep hours. Furthermore, burnout was prevalent among dentists, particularly in terms of emotional exhaustion and personal accomplishment, which were strongly associated with increased stress levels. The results underscore the need for targeted interventions and support mechanisms tailored to factors facing dentists, especially among females and those who receive inadequate sleep. The relationship between burnout and stress levels highlights the intricate connection between these phenomena.
