BACKGROUND
Research on gender inequality is crucial as it unveils the pervasive disparities that persist across various domains, shedding light on societal imbalances and providing a foundation for informed policy-making.
AIM
To investigate gender differences in scientometric indices among faculty members in dental schools across Iran. This included overall data and speciality-specific data.
METHODS
The publication profiles of academic staff in all dental schools were examined using the Iranian Scientometric Information Database (ISID, http://isid.research.ac.ir). Variables analyzed were working field, academic degree, the total number of papers, papers per year, total number of citations, percentage of self-citation, h-index, g-index, citations per paper, gender, university type, number of years publishing, proportion of international papers, first-author papers, and corresponding-author papers. Mann-Whitney and Kruskal-Wallis nonparametric tests were used to analyze the relationship between background characteristics and scientometric indicators. The extracted data were analyzed using R v4.0.1.
RESULTS
The database included 1850 faculty members, of which about 60% (1104 of 1850) were women. Men (n = 746) had a higher number of papers (6583 vs. 6255) and citations (60410 vs. 39559) compared with women; 234 of the 376 faculty members with no papers were women. Almost half of the women (N = 517 of 1104) were in Type 2 universities, and nearly half of the men (N = 361 of the 746) were faculty members at Type 1 universities (Type 1 universities ranking higher than Type 2 and 3 universities). The medians of scientometric indices were higher in men, except for self-citation percentage (0 (IQR = 2) vs. 0 (IQR = 3), P = 0.083), international papers percentage (0 (IQR = 7.5) vs. 0 (IQR = 16.7), P<0.001). The proportion of corresponding-author papers was more than 62% higher in women (25 (IQR = 50) vs. 15.4 (IQR = 40), P<0.001). Men had a two-fold higher median h-index (2 (IQR = 4) vs. 1 (IQR = 3), P<0.001). Restorative dentistry and pediatric dentistry had the highest men-to-women ratios (1.5 for both). Dental materials and oral and maxillofacial surgery showed the lowest men-to-women ratios (0.42 and 0.5, respectively).
CONCLUSIONS
Women made up the majority of dental faculty members in Iran. Nevertheless, men showed better scientometric results in several significant indices. Having identified scientometric information reflecting differences across faculty members, further research is now needed to better understand the drivers of these differences.

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.

INTRODUCTION
Wet oral environment may have deleterious effects on performance of the composites due to influences of water sorption and solubility. The study evaluated the hydrolytic degradation caused because of water sorption and solubility of silorane and methacrylate-based dental composites.
METHODS
Ten disc samples (2 mm × 10 mm) were prepared. Samples were analyzed for water solubility and sorption according to ISO 4049:2000 regulations and tested for mass gain or loss following immersion in water or in artificial saliva at 1 day, 15 days, and 30 days period. Student's 't' test, repeated measures analysis of variance (ANOVA), and Tukey's post-hoc tests determined statistical significance of the experimental results with global significance set at P = 0.05.
RESULTS
Considerable sorption and solubility was observed with time in both materials on immersion. Silorane composites showed lower water sorption and solubility than methacrylate-based composite (MBC). Artificial saliva demonstrated higher sorption and solubility compared to distilled water.
CONCLUSION
Silorane composites display enhanced hydrolytic stability even after a month of immersion in contrast to conventional methacrylate-based composites (MBCs), making it a better alternative to MBC resins clinically.

Comparative Study
An Immunohistochemical and Histological Study of the Animal Periodontal Ligament During Orthodontic Force Application with Concomitant Application of Electric Current - An Animal Study.
INTRODUCTION
The application of direct current can have a significant impact on the rate of tooth movement and surrounding periodontal ligament collagen turnover. This study aims to provide insight into the optimal characteristics of applied current to achieve enhanced tissue response.
METHOD
Eighteen male Wistar rats were divided into three groups (I, II, and III). Split mouth design was used, and each side was allocated into an experimental group or control group. Experimental sides of groups I, II, and III received 20, 10, and 15 μA of current (15 min, twice daily for 3 days). Both the experimental and control groups receive an orthodontic force via the NiTi closed coil spring. The amount of tooth movement was determined daily. Immunohistochemistry slides were scored using the immunoreactive scoring (IRS) system for collagen types I and III. One-way Analysis of Variance (ANOVA) and Tukey post hoc test were used to analyse the rate of tooth movement, while Mann-Whitney test was used to analyse IRS distribution between control and experimental groups.
RESULTS
Compared with the control group, there was a statistically significant difference in tooth movement in all the experimental groups, with group 3 showing the maximum rate on days 2 and 3. This was supported by immunoreactive scores for both collagen types I and III.
CONCLUSIONS
After 72 hours, the expression of collagen types 1 and 3 increased significantly for group III. This finding was in harmony with the rate of tooth movement, which was maximum for group 3 (15 μA) as compared to other groups.

Randomized Controlled Trial Comparative Study
AIM
This study aimed to compare the efficacy of subgingivally applied probiotics as an adjunct to scaling and root planing (SRP) vs SRP alone in patients with periodontitis.
MATERIALS AND METHODS
Patients diagnosed with periodontitis, with probing pocket depth (PPD) of 5-7 mm on at least two teeth on contralateral sites, were selected for the study and randomly allocated to the test group (n = 31) who underwent SRP along with subgingival application of probiotic paste and the control group (n = 31) who underwent only SRP. Clinical parameters were evaluated in both groups at baseline and after 12 weeks. The viability of probiotic bacteria was evaluated in the test group at baseline, day 4 and day 8.
RESULTS
All clinical parameters showed a statistically significant difference between baseline and 12 weeks on intragroup and intergroup comparison, with a greater improvement in the test group. Microbiological evaluation showed that the mean colony-forming units (CFUs) in the test group were 38.39 ± 7.76, 7.25 ± 2.72 and 1.57 ± 1.29 at baseline, day 4 and day 8, respectively. The mean CFUs significantly reduced with an increase in time from baseline to 8-day time interval.
CONCLUSION
It was seen that the probiotic bacteria remained viable in the periodontal pocket for up to 8 days after placement, but stable improvements were seen in all clinical parameters even at 12 weeks, indicating its prolonged efficacy. Thus, commercially available probiotics can prove to be an inexpensive method to treat periodontitis when combined with SRP.

BACKGROUND
Dental radiography is an integral part of intraoral evaluation. Children are often uncomfortable during the placement of film or sensor due to the impingement of the soft tissues. Thus, the perception of pain with three intraoral radiographic methods in children was evaluated using three subjective pain rating scales.
AIM
To evaluate the discomfort with three different techniques, that is, intraoral periapical (IOPA) radiograph, charge-coupled device (CCD), and photostimulable phosphor (PSP) luminescence (PSPL), using the Wong-Baker Faces Pain Rating Scale (WBFPRS), numerical rating scale, and visual analog scale (VAS).
MATERIALS AND METHODS
A sample of 35 children aged 6-12 years were divided into two groups: group 1 (6-8 years) and group 2 (9-12 years). For each child, simulations of the three radiological methods (IOPA, CCD, and PSPL) were performed. The meaning of each facial expression on the WBFPRS, VAS, and the numbers on the numerical rating scale was explained to each child before the procedure.
STATISTICAL ANALYSIS USED
A one-way analysis of variance (ANOVA) test and paired-samples t-test are used.
RESULTS
The results revealed that the CCD sensors elicited higher pain scores than those obtained with IOPA and PSPL, whereas the IOPA film showed the least pain score. Higher score values were obtained in group 1 than in group 2, indicating that children aged 6-8 years felt higher discomfort than the 9- to 12-year age group for the same procedure. This difference was statistically significant (P < 0.001).
CONCLUSION
It was concluded that conventional IOPA films were tolerated better by children when compared to PSP plates and CCD sensors.

INTRODUCTION
Measurement of dental caries is imperative for its prevention and control. The present study was conducted with the aim of developing a dental caries index that is reliable, reversible, and valid. A cross-sectional study was designed and conducted at the outreach dental clinics of a dental school in India.
METHODS AND MATERIAL
A total of 219 patients visiting outreach centres participated in the study. Patients attending outreach dental clinics aged 15 years and above, who were dentate and affected by dental caries, were included. Clinical examination was done under clinical conditions with dental chair lighting. Decayed Missing and Filled Teeth (DMFT) and Index of Caries Experience (ICE) were recorded using the visuo-tactile method according to the index criteria.
RESULTS
The relationship between the DMFT and ICE was determined. Results showed that the DMFT from ICE had good correlation. The decayed teeth index (DTI) score varied from decayed teeth (DT) according to age and sex. DTI was significantly higher for females than for males and higher among younger age groups than older ones, but DT did not exhibit the differences.
CONCLUSIONS
ICE is a new system in which the proviso is to measure the non-cavitated lesions and health of permanent dentition. DMFT and ICE have good correlation. DTI is more sensitive than the DT score.

Comparative Study Randomized Controlled Trial
AIMS
Compare the efficacy of 2% lidocaine with adrenaline (1:200,000) and 4% articaine with adrenaline (1:100,000) in inferior alveolar nerve block prior to extraction of bilateral teeth posterior to canine in interval of one week.
METHODS AND MATERIAL
Thirty-five patients were selected for the study. Patients were divided into two different groups: Group 1 - (2% lignocaine with adrenaline (1:200,000)) and Group 2 - (4% articaine with adrenaline (1:100,000)) solution. The study variables for each anaesthetic agent were: onset of action and depth of anaesthesia. A pulp tester was used to demonstrate quantitative values and a visual analogue scale (VAS) was used for qualitative evaluation of the two anaesthetic drugs in 2 min cycle for 10 min with respect to test canine. Anaesthesia was considered successful when pulp tester value 64 was achieved in 10 min for both the anaesthetic agent.
STATISTICAL ANALYSIS USED
The difference in the efficacy of lignocaine and articaine was analysed using Student's t test. Within group comparison of the response to the pulp vitality test and VAS over various time periods was analysed using repeated measures Analysis of Variance (ANOVA) with post-hoc Bonferroni test.
RESULTS
Data analysis showed statistical differences in onset and depth of anaesthesia between the two groups (P < 0.05).
CONCLUSIONS
4% Articaine with adrenaline (1:100,000) onset of action is faster and depth of anaesthesia is better compared to 2% lignocaine with adrenaline (1:200,000). Many previous studies reported onset of anaesthesia, but this study evaluates onset and depth of both the anaesthetic agent quantitatively and qualitatively.

BACKGROUND
Periodontitis and type 2 diabetes are chronic inflammatory diseases that increase inflammatory Interleukin-6 (IL-6) levels that induce the production of advanced glycation end products (AGEs) causing receptor activator of nuclear factor-kappa B ligand (RANKL) expression on osteoclasts, contributing to further alveolar bone destruction.
AIM
To assess the role and diagnostic potential of salivary IL-6 (SIL-6) in the detection and evaluation of chronic periodontitis (CP) and tooth loss in type 2 diabetes mellitus (T2DM).
MATERIALS AND METHODS
This cross-sectional study comprised 240 subjects aged 30-69 years with minimum of 15 natural teeth. Fasting, unstimulated whole saliva was collected, full-mouth intra-oral examination and periodontal evaluation were performed using PCP-UNC 15 probe and glycaemic (HbA1c) levels were analysed by high-performance liquid chromatography (HPLC) method. Subjects were categorised into four groups of 60 participants each: Group 1 (controls); Group 2 (CP); Group 3 (T2DM with CP); Group 4 (T2DM with CP and tooth loss). Salivary IL-6 levels were quantitatively assessed by enzyme-linked immune sorbent assay method.
RESULTS
Average SIL-6 levels were significantly elevated in Group 4 (T2DM with CP and tooth loss) (P = 0.001) and in severe periodontitis (P = 0.001). Karl Pearson Correlation found a significant association between average SIL-6 and average periodontal pocket depth (APPD) (r = 0.180), average clinical attachment loss ≥3 mm (ACAL3) (r = 0.289) and severity of periodontitis (r = 0.3228). The receiver operating characteristic (ROC) curve depicted an overall sensitivity of 53.3%, specificity of 68.6% and accuracy of 60% in the detection and assessment of CP in T2DM with tooth loss.
CONCLUSION
IL-6 in saliva is a valuable, non-invasive biomarker in the detection and evaluation of CP in T2DM with tooth loss.
