Metastasis to jaw bones from renal cell carcinoma as the sole primary source: Systematic review.

Renal cell carcinoma (RCC) has been known for its high propensity of metastasis to unusual locations, and jaw bones (JBs) are one among those sites. The literature has reported several studies analyzing metastatic tumors to the oral region, but very little research work has been published to date to analyze solely JB metastasis (JBM) via RCC. The goal of this study was to examine the published cases of metastasis to JBs from RCC as the sole primary source till date.

Self-driven micromotors loaded with photosensitive adhesives and their application in dentin sensitivity.

Dentin hypersensitivity is primarily caused by the exposure of dentinal tubules due to various factors, so the key to treatment is to effectively seal these exposed tubules. However, traditional dentinal tubule sealants used in clinical practice often fail to adhere securely to the tubule surface when exposed to external stimuli, resulting in a recurrence of sensitivity. In this study, we developed a silicon micromotor that moved autonomously and loaded with silver nanoparticles and a photosensitive adhesive for dentin sensitivity therapy.

Optimising titanium implant stability and infection resistance through iron nanoparticle coatings: A preclinical investigation.

Background: Attaining adequate osseointegration and mitigating infections are paramount issues in implantology, especially within dental and orthopaedic domains. Titanium implants have been utilised for their biocompatibility and mechanical strength; yet, problems such as peri‑implant infections and inadequate bone integration may undermine their efficacy. Coating titanium implants with iron nanoparticles (FeNp) has surfaced as a promising approach to improve osseointegration and antibacterial characteristics.

Altered Passive Eruption among Patients Visiting Dental Outpatient Department in a Tertiary Care Center: A Descriptive Cross-sectional Study.

Introduction: The eruption of teeth is considered to be a continuous phenomenon. Two types of eruption are possible namely, active and passive eruption. Failure in passive eruption (by the apical movement of gingiva from the enamel surface) generally results in a clinical condition known as altered passive eruption.

Comparative Evaluation of Serum Levels of Vitamin B12, Folic Acid, and ESR in Chronic Periodontitis Among Smokers, Gutkha Chewers, and Type 2 Diabetic Patients: A Cross-Sectional Study.

Aim: The purpose of this research is to determine the relationship between periodontal disease severity, cigarette smoking, gutka chewing, and type 2 diabetes mellitus by estimating, correlating, and comparing blood levels of vitamin B12, folic acid, and erythrocyte sedimentation rate (ESR) in patients with chronic periodontitis.

Methodology: A cross-sectional research study conducted at Rama Dental College Hospital and Research Centre in Kanpur involved 240 patients with chronic periodontitis, who also exhibited additional risk factors including smoking, gutkha chewing, and type-2 diabetes mellitus. Divided into four groups of 60 individuals each, the study aimed to estimate and correlate blood levels of vitamin B12, folic acid, and ESR.

Applications of robot-assisted UV disinfection in dentistry.

Maintaining a microbial-free environment in healthcare facilities is more widely recognized as an essential component of therapies to minimize transmission of viruses associated with healthcare sector. The global spread of COVID-19 and recent outbreaks have presented humanity with previously unheard-of challenges. The development of autonomous disinfection robots seems to be necessary given the urgent need for constant sterilization in the face of a labor shortage.

Systemic Factors Affecting Orthodontic Treatment Outcomes and Prognosis-Part 2.

This article explores the various challenges systemic conditions can pose before and during orthodontic treatment. Cardiovascular conditions like infective endocarditis require antibiotic prophylaxis before certain orthodontic procedures are started. Patients with bleeding disorders require special considerations in regards to viral infection risk and maintenance of excellent atraumatic oral hygiene.

Systemic Factors Affecting Orthodontic Treatment Outcomes and Prognosis - Part 1.

This article explores the intersection of various systemic conditions with orthodontic treatment. Renal diseases, including chronic kidney disease and renal transplant, present challenges such as delayed tooth eruption and gingival overgrowth, necessitating careful orthodontic planning and collaboration with physicians. Liver diseases, particularly hepatitis, heighten the risk of periodontal disease and mandate strict infection control measures during orthodontic procedures.

Alterations in internal threads of implant analog of different materials after multiple reuse.

The impact of multiple reuse on the alterations in internal threads of four different implant analogous composed of different materials (stainless steel (SS), aluminum (Al), titanium (Ti), and zirconia (Zr) by utilizing two die materials at different time durations is of interest to dentists. The spacing between the threads was measured using the impressions created for the interior threads of implant analogs, or replicas by stereomicroscope set to x50 at 0th, 3rd, 6th, 9th, and 12th interval. It was observed that there was decrease in distance between threads 1-2 as the increasing reuse at increasing time intervals in all implants analogs.

Electrically Evoked Stapedius Reflex Measurements in Cochlear Implantation and its Application in the Postoperative Fitting Process.

Measuring the electrically evoked stapedius reflex during the fitting of cochlear implants (CIs) provides a reliable estimation of maximum comfort levels, resulting in the programming of the CI with high hearing comfort and good speech understanding. Detection of the stapedius reflex and the required stimulation level on each implant channel is already being performed during surgery, whereby intraoperative stapedius reflexes are observed through the surgical microscope. Intraoperative stapedius reflex detection is both an indicator that the auditory nerve is responding to electrical stimulation up to the brainstem and a test for the ability to perform postoperative stapedius reflex measurements.
