PURPOSE The complex miniature architecture of dental burs and endodontic files makes precleaning and sterilization difficult. Devising a sterilization protocol for endodontic files and dental burs requires care, and some have suggested that these instruments be considered single-use devices. One purpose of this study was to determine the effectiveness of various sterilization techniques current...

Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. Additives can either accelerate the decomposition rate of ozone or have a stabilising effect of the ozone decay. By contro...

Tubal sterilization is an increasingly common method of contraception. Although pregnancy after sterilization is uncommon, it can occur and may be ectopic. It is widely believed that any pregnancies after tubal sterilization will generally occur during the first year or two year after the procedure. Surprisingly, failures are not limited to the first year or two, but continued to appear at each...

INTRODUCTION Female sterilization has long been the most popular method of family planning (FP) in Pakistan, and yet most public health experts feel it contributes little to controlling family size or to population welfare. We used Pakistan Demographic Health Survey (PDHS) data to understand the role female sterilization plays in the overall context of FP in Pakistan. METHODS We performed a s...

Complex of bismuth, an anti-inflammatory drug, was studied by EPR spectroscopy. The aim of this study was to determine concentrations and properties of free radicals formed during thermal sterilization of bismuth subgallate according to pharmacopoeia norms to optimize its sterilization process. Different temperatures (160°C, 170°C, and 180°C) and times (120 minutes, 60 minutes, and 30 minutes) ...

BACKGROUND AND OBJECTIVES The safety and efficacy of female hysteroscopic sterilization using the Essure system has been well documented. Given the marked differences in the execution of hysteroscopic and laparoscopic sterilization, the objective of this study was to assess the experience of pain postprocedure between the 2. Secondary end-points included postoperative pain medication, time to r...

BACKGROUND Steam sterilization is an essential part of infection prevention. The literature shows that sterilization of medical instruments containing channels is not trivial. Phaco hand pieces have a simple configuration: a device contains a channel with a constant radius. No literature was found indicating whether the sterilization conditions on the inner surface of a phaco hand piece are inf...

Copper NiTi wires were introduced by Sachdeva R and Miyasaki S in 1994. This latest innovation in the evolutionary scale gives us the opportunity of choosing the force level by choosing the temperature at which the wires will deliver its optimum force level. With so many advantages and their ability to return to their original form coupled with the high cost of copper NiTi many clinicians start...

Background As in other states of India, female sterilization is the most widely used contraceptive method in Kerala where women have higher levels of education compared to most other states in India. This paper describes the use and preferences of contraceptive methods among young married women in Trivandrum district, Kerala, India. Subjects and methods A community-based cross-sectional surve...

In the food industry field, heat sterilization, as a routine sterilization approach, is widely adopted. During such a process, the prepackaged foods in cans or pouches are put into a autoclave which is filled with the hot water or steam used as the medium of the thermal process. People can, under some particular requirements, have the appropriate control of the sterilization process by adjustin...
