Comparative characterization and analysis of telomere length in stem cells derived from deciduous and permanent teeth
Conclusion: SHED and DPSCs displayed similar morphology, proliferation rates, and phenotypicfeatures. The relative telomere lengths were slightly shorter in DPSCs than SHED, but the valueswere not significantly different. Thus, SHED and DPSCs can be considered as recognized sourcesfor regenerative applications in dentistry.Key Words: Deciduous teeth, dental pulp, stem cells, telomere (Source: Dental Research Journal)

Effect of different mouthwashes on the shear bond strength and surface roughness of intraoral and heat ‑cured soft liners
Conclusion: SBS of either group of liners did not change in both mouthwashes; However, SBS ofheat ‑polymerized liner was higher than autopolymerized in all groups. Ginger extract‑containingmouthwash increased SR of autopolymerized liner used in this study; whereas, there were nosignificant changes in the heat ‑cured liner. According to this study, CHX can be used for thedisinfection of prosthesis lined with either type of liners.Key Words: Dentistry, dentures, mouthwashes (Source: Dental Research Journal)

A comparative evaluation of wear resistance of three types of artificial acrylic teeth after removing the glaze layer
This study aimed to compare the wear resistance of three types of artificial acrylic teeth before and after removing the glaze layer. Materials and Methods: This in vitro study compared three types of artificial acrylic teeth, namely, Finex (F), SR Orthotyp DCL (S), and Vita Physiodents (V) in six groups (n = 10). Half of the artificial teeth of each brand underwent 0.5 ‑mm buccal reduction to remove the glaze layer (groups FC, SC, and VC). The teeth were thermocycled and placed in a chewing simulator. The teeth with and without the glaze layer were weighed before and after the wear test. The data were analyzed using ANC...

Redefining aerosol in dentistry during COVID ‑19 pandemic
The corona virus malady 2019 (COVID-19) pandemic has rekindled the well established argument regarding the role of dental aerosol in transference of severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). Aerosols and droplets are generated amid innumerable dental procedures. With the commencement of the COVID ‑19 pandemic droplet, a review of the infection/disease control strategies for aerosols is required. We do not know where this pandemic is directed. We do not have conclusive evidence for an optimal management strategy. Every day brings in varying information, so recognizing the hazard created by aerosols wi...

An atypical case report of extensive mucormycotic osteomyelitis of maxilla as a consequence of post ‑COVID complication
Saprophytic molds such as Mucor, Rhizopus, and Absidia cause mucormycosis, a fungal infection.These saprophytic fungi are common in the environment and have a strong proclivity for invadingmajor blood arteries, causing tissue ischemia, necrosis, and infarction. They have been linked toimmunocompromised individuals with a history of diabetic ketoacidosis, corticosteroid medication,HIV infection, malignant lymphomas, and patients currently receiving and recovering from COVID ‑19treatment. The foregoing is the case of a 78 ‑year‑old COVID‑19 recovered male who presentedwith a primary complaint of upper tooth movement ...

Evaluation of Epstein –Barr virus expression in oral squamous cell carcinomas
Conclusion: EBV expression was observed in most of the OSCCs, especially in poorly differentiatedtumors. The pathogenesis of OSCCs may be related with EBV. OSCCs in buccal mucosa and floorof the mouth have more frequently of EBV expression. Future studies on the mechanisms of EBVand their role in OSCC are required with larger sample sizes.Key Words: Epstein –Barr virus, oral cancer, squamous cell carcinoma (Source: Dental Research Journal)

Effect of immersion in sodium hypochlorite on cyclic fatigue resistance of RaCe, HyFlex CM and XP ‑endo shaper files
This study assessed the effect of sodium hypochlorite on cyclic fatigue resistance of RaCe, HyFlex CM and XP ‑endo Shaper files. Materials and Methods: In this in vitro, experimental study, 90 RaCe, HyFlex CM and XP‑endo Shaper files (n = 30 of each) were divided into two groups (n = 45). Group 1 included 15 files of each rotary system, which were immersed in 37°C sodium hypochlorite (5.25%) for 5 min . Group 2 files were immersed in 37°C saline for 5 min. The files underwent cyclic fatigue testing using simulated root canals in which, the rotary files could freely rotate until fracture. Time of fracture was recorded...
