The Process of Dry Heat Sterilization Work

图片
Dry heart sterilization takes longer than steam sterilization due to the inefficiencies of heating air with a very low moisture content. Compared to steam sterilization, which requires a temperature around 121 degrees Celsius to be maintained for approximately 30 minutes, dry heat sterilization requires higher temperatures of around 180 degrees Celsius to be effective at neutralizing biological contaminants and their spores. For this reason, dry heat sterilization is most appropriate for medical devices which are heat resistant but susceptible to water damage which would make steam sterilization a poor choice. Hot air ovens are the most common setup for dry heat sterilization of tools composed of metal or glass. Vials containing biologic drugs such as vaccines are often sterilized using a dry heat method prior to filling to ensure they contain no microorganisms. How does Dry Heat Sterilization Work? Dry heat sterilization uses high temperatures to kill microorganisms...

Children's orthodontics and its role alongside pediatric dentistry

图片
Orthodontic treatment with orthodontics instruments and materials in young children is known as preventive orthodontics and can be started in children 6 or 7 years of age. At that age, teeth are developing and the jawbone is still growing, so some problems may be easier to treat. Not necessarily all problems seen by the pediatric dentist should be treated by preventive orthodontics. Two problems that require early intervention are cross-bite and overbite. A cross bite can cause the jaw to grow irregularly. The "protruding teeth" on the bites can be fractured more easily, i.e. the medical team can evaluate them to understand the real severity of the problems and how they will be in the long term. Alongside preventive orthodontics, interceptive orthodontics also actively acts on the part of pediatric dentistry to correct existing but identified occlusion problems at an early stage in an attempt to avoid incorrect craniofacial development in adults. Interceptive orth...

What should pay attention to when choosing endo motor

What should pay attention to when choosing endo motor Endodontic instrumentation has advanced significantly in recent years with a range of powered rotary and reciprocating systems that can make root canal treatment easier to perform. Endodontic electric motors with apex locator are a part of this advancement as they provide clinicians with the ability to use endodontic files with constant and precise torque suited to the canal being treated. Many of these systems offer programmable settings, automatic reverse functions designed to reduce file breakage, and some even feature integrated apex locators. Some electric dental handpiece systems can even be used for endodontics along with a full range of other functions.What should take into consideration when choosing endomotor motor? The following 6 factors you need pay attention to. 1. Rotation vs Reciprocation: Rotary vs Reciprocation Rotary endodontics was able to deliver great results with a lesser risk of complica...
