Bonded retainers best vacuum-formed retainers to maintain incisor alignment in maxilla and mandible after 12 months of retention: Study

Bonded retainers are best vacuum-formed retainers in maintaining alignment of incisors in the maxilla and mandible after 12 months of retention suggests a study published in the Orthodontics and Craniofacial Research.

A study compared the clinical effectiveness of V-bend bonded retainers (BR) versus vacuum-formed retainers (VFR) regarding their capacity to maintain treatment stability and survival rates after 12 months. Patients finishing orthodontic treatment were randomly allocated into two groups. The Bonded retainers group received maxillary and mandibular BRs in the lingual surfaces of the anterior teeth. The VFR group received VFRs right after fixed appliance removal. The patients were evaluated at four time points: at fixed appliances removal (T0), after 3 (T1), 6 (T2) and 12 months (T3). In each time-point digital models were obtained and analysed with the OrthoAnalyzer™ software. Treatment stability based on occlusal outcomes and retainers' survival rates were evaluated. Intergroup comparisons were performed using Mann–Whitney U-tests. The Kaplan–Meier survival plot and the log-rank test assessed the retainers' survival. Results: Both Bonded retainers and VFR groups included 25 patients. The groups were comparable regarding their baseline characteristics. Up to 6 months, both retainers were equally effective; however, after 12 months, Bonded retainers were more effective in maintaining the incisors' alignment in the maxilla and mandible than the VFRs. No differences were noticed in the intercanine and intermolar widths, overjet and overbite. There were no differences regarding the retainers' survivability in both arches. Bonded retainers were more effective in maintaining the alignment of the incisors in the maxilla and mandible compared to VFRs after 12 months. Both retainers presented the same survival rates after the same period.

'Details sought include Third-party info, hence exempted under RTI Act': NMC on RTI query on Faculty Gap in Medical Colleges

Image
New Delhi:  Stating that the details sought under the RTI includes third-party information, the National Medical Commission (NMC) has refused to disclose the names of the medical colleges that fell short on faculty counts and other teaching infrastructure. Recently activist Dr. KV Babu filed an application under the Right to Information Act seeking the details of the notices issued by the NMC Undergraduate Medical Education Board (UGMEB) to the medical colleges for deficiencies in Clinical Material and staff during the period from 01/01/2023 to 30/04/2024. He also sought to know the details of the fine imposed or the action taken by the NMC UG Board from 01/01/2023 to 30/04/2024. In response, the Apex medical regulatory body in India has said that the concerned information includes third party information. "Since the information sought by you, includes third party information, hence the same is exempted for as per Section 8(1) (j) of the Right to Information Act, 2005," th...

Zasocitinib therapy highly efficacious for treatment of severe plaque psoriasis: JAMA

Image
A recent study published in the Journal of American Medical Association revealed that Zasocitinib could be a breakthrough in the treatment of moderate to severe plaque psoriasis. Psoriasis is a chronic inflammatory skin condition characterized by red, scaly patches, affects millions throughout the globe. While several treatments exist, the demand for new, effective, and well-tolerated oral therapies remains high. Zasocitinib, a highly selective allosteric tyrosine kinase 2 (TYK2) inhibitor, emerges as a promising candidate to meet this need. This trial was conducted between August 2021 and September 2022 across 55 centers in the US and Canada and found that Zasocitinib not only significantly improved skin clearance in patients but also expressed a favorable safety and tolerability profile. The study enrolled a total of 287 participants aged between 18 and 70 years, each with a Psoriasis Area and Severity Index (PASI) score of 12 or greater, a Physician’s Global Assessment score of 3...

New wearable laser device may monitor brain blood flow to gauge stroke risk, reports research

Image
Researchers have developed a laser-based device that can be placed on the head to non-invasively monitor changes in brain blood flow and volume. The new device could one day help save lives by offering a direct and simple way to assess stroke risk based on physiological markers rather than indirect markers like lifestyle factors. Strokes occur when blood flow to the brain is blocked or reduced, causing debilitating brain cell damage. With about 15 million people worldwide affected by strokes each year, it is the second leading cause of death and a leading cause of long-term disability. “The lack of a cost-effective and scalable stroke risk assessment system complicates long-term stroke prevention because a physician can’t tell whether a patient’s risk is stable or worsening,” said research team member Simon Mahler, a postdoctoral scholar in Changhuei Yang’s laboratory at the California Institute of Technology. “This new method could help catch early signs of increased stroke risk, w...
