Purpose: The study aimed to compare clinical and radiographic parameters of peri-implant site of laser-microgrooved implants with either laser-microgrooved or regular machined prosthetic abutment post 3 years of early loading.Method: Twenty edentulous sites of systemically and periodontally healthy individuals were allocated into two groups in this prospective, two-armed, randomized double-blinded clinical trial in 1:1 ratio, wherein each site received laser-microgrooved implants with either laser-microgrooved or machined prosthetic abutments. Outcome measures included full-mouth plaque (FMPS%) and bleeding score (FMBS%), site-specific plaque (SPS%) and bleeding score (SBS%), peri-implant sulcus depth (PISD mm), and mean crestal bone loss (MCBL mm) evaluated at baseline (6 weeks), 1 and 3 years post-early loading. Mean and standard deviation of all parameters were estimated, between groups and at different time points using independent and pairedt-test, respectively, Normality was checked using Kolmogorov–Smirnov test and Shapiro–Wilk test,Pvalue ≤ 0.05 was considered as statistically significant.Results: Three-year follow-up of test group showed statistically significant reduction in SPS, SBS, PISD (Pvalue ≤ 0.001). The MCBL reduced from 1.93 mm to 0.61 mm (Pvalue ≤ 0.001); in other words, a bone gain of 0.15 mm was obtained in the test group.Conclusion: Within the limitations of the present study, laser-microgrooved implants loaded with laser-microgrooved prosthetic abutments showed superior results clinically and radiographically when compared to loading with machined abutments.

Background: Dental root coverage, crucial in managing gingival recessions, traditionally utilizes subepithelial connective tissue grafts. However, this approach has limitations such as donor site morbidity and graft availability. Recent studies have introduced platelet-rich fibrin (PRF) as an alternative, leveraging its regenerative potential and growth factors. Despite the promise, comparative assessments between PRF and conventional grafts remain limited. This research probes whether PRF, when used beneath a modified Ruben's mixed flap, could provide comparable or superior dental root coverage than a subepithelial connective tissue graft. Material/Methods: We enrolled 30 patients exhibiting Miller's class I and II recession in this comparative case series. Patients were randomly assigned to receive either a connective tissue graft (15 patients) or a PRF matrix (15 patients), both covered by a modified Ruben's mixed flap.Results: Clinical parameters, including full mouth plaque scores, bleeding scores, probing sulcus depth, clinical attachment level, gingival position assessment, width, and thickness of attached gingiva, were assessed in both the control and test groups at baseline, 6 months, and 12 months post-surgery. Significant differences were observed at all intervals. At the 12-month mark, the control group (connective tissue graft) achieved 91% complete root coverage, while the test group (PRF matrix) achieved 86%. However, this difference was not statistically significant.Conclusions: The study outcomes suggest comparable gains in root coverage and attached gingiva between the connective tissue graft and PRF matrix groups. Thus, the results support our hypothesis that a subepithelial PRF matrix can serve as a viable alternative to a subepithelial connective tissue graft for treating dental root coverage.

Background: World Health Organization stated that “noise must be recognized as a major threat to human well-being.” The operating tools commonly used in dental clinics such as airotor, micro motor, sonic and ultrasonic scalers, compressor, suction generate potential noise which has hazardous effects on the dentist, dental assistants/technicians and also patients, resulting in both auditory and non-auditory effects. Aim: The aim of the present study is to assess the knowledge and Awareness of Noise Pollution Generated in Dental Care Facilities among Clinicians using a structured questionnaire in-order to sensitize the dental fraternity on the importance of preventing occupational hazards. Materials and Methods: Informed Consent was obtained from 100 voluntary dental professionals and information regarding their knowledge and awareness towards noise pollution in dental clinics was obtained by a self-made structured questionnaire comprising 22 questions. The Data was compiled and analysed with SPSS 22 software. Results: The study population consisted of 31 male and 69 female dentists, out of which 85% perceived noise in dental operatory as an occupational hazard in terms of annoyance factors like tinnitus, difficulty in focussing and headache. Only 57.1% of the subjects were aware of the Maximum permissible levels of noise in a dental set up. Around 74.3% of the subjects have taken measures for noise reduction in practice, most common among them is placing compressors outside the clinic (28%). Conclusion: In the era of digitalisation, we face numerous consequences in our workplace due to noise. This study has thrown insights on the general awareness levels of Noise induced Occupational Hazard among dentists which is not very satisfactory, and thus necessary steps need to be followed to combat such factors which may have long term effects like Tinnitus, Headache. Dentists at the least must avoid other noise producing hazardous activities and switch to noise free environments as much as possible.

Nanotechnology is a cutting-edge concept that is evolving manifolds in various fields of science and medicine and is by no means exceptional to dentistry. Nanotechnology is popularly known as the ‘science of the small’ that deals with particles of size 1-10nm. Methods like top-down or bottom-up approaches are used in manufacturing nanoparticles and nanorobots, catering to the needs of medical diagnostics and therapeutics. Nanorobotics advances medicine through miniaturization from microelectronics to nanoelectronics. Nanotechnology can be applied to all fields of dentistry such as to create nano implants, nano-drug delivery systems, nanocomposites and nano impression materials. Additionally, it helps in orthodontic tooth movement, alleviating hypersensitivity, and effective anesthesia. This paper highlights the various applications of nanotechnology in dentistry and also mentions the clinical trials performed to have a more focused approach to practicing nanodentistry. Apart from this the paper briefly explains the benefits of integrating artificial intelligence and nanotechnology for creating more personalized treatment options and also its role in Covid 19 vaccines.

Dielectric barrier discharge plasma treatment on implant surfaces allows for increased osseo-integration by way of improved cellular adhesion, proliferation and differentiation. The physicochemical properties including contact angle and hydrophilicity capacitate for additional benefits like immediate cell seeding thereby prolonging the time for native cells to migrate first, rather than bacterial inhabitation. The review is aimed at elaborating the literature on contact angle and hydrophilicity of implant surface with plasma treatment. A total of 32 articles were identified after digital search from databases like PubMed/ Medline, Elsevier, Cochrane Library. Bias analysis was performed using the RoB tool for animal interventional studies (SYRCLE’s RoB tool). The Bias analysis evaluating the contact angle and hydrophilicity showed that all the studies showed reduced contact angle and increased hydrophilicity. Thus all the studies show significant increase in contact angle thereby adding to the benefit of plasma treatment to be a major game changes in integration of biological implants.

Background and Objectives: The study aimed to compare the mean crestal bone level (CBL) and peri-implant soft tissue parameters in laser micro-grooved (LMG) platform switched implants and abutments (I&A) post 1 year of functional loading among non-diabetic and type II diabetic individuals. Materials and methods: Patients with an edentulous site having minimum bone height and width of ≥13 mm and ≥6 mm, respectively, were divided into two groups: (i) Non-diabetic-8 (control) and (ii) diabetic-8 (test). LMG Implants were placed and loaded immediately with a provisional prosthesis. Mean crestal bone level (MCBL) was evaluated radiographically at baseline and at 1 year. Peri-implant attachment level (PIAL) and relative position of the gingival margin (R-PGM) were recorded. Implant stability quotient (ISQ) level and implant survival rate (ISR) were evaluated at 1 year. Results: Early MCBL within the groups 1 year postloading was similar both mesially and distally (control—0.00 to 0.16 mm and 0.00 to 0.17 mm, respectively; test—0.00 to 0.21 mm and 0.00 to 0.22 mm, respectively) with statistical significance (p ≤ 0.003, p ≤ 0.001 and p ≤ 0.001, p ≤ 0.001, respectively). However, intergroup comparison showed no significant difference statistically in the MCBL in 1 year post functional loading. The peri-implant soft tissue parameters showed no significant difference between the groups. ISQ level between both groups did not reveal any significant changes (p ≤ 0.92), and ISR was 100%. Conclusions: LMG Implants resulted in minimal and comparable early crestal bone loss and soft tissue changes post 1 year of functional loading in moderately controlled diabetic and non-diabetic individuals, suggesting that this could be a reliable system for use in systemically compromised individuals.
