Treatment Outcome and Root Canal Preparation Techniques: 5-Year Follow-Up.

Objective: This study aims at comparing treatment outcome and tooth survival of root canal-filled teeth following manual vs rotary instrumentation techniques over a 5-year period.

Methods: This was a single-centre study conducted as a follow-up to a short-term parallel-arm randomised controlled noninferiority trial in which root canal treatment was performed on teeth using either rotary or manual instrumentation. Patients were monitored at post 6-month, 1-year, 4-year, and 5-year review periods by blinded evaluators.

Mercury hygiene and biomedical waste management practices among dental health-care personnel in public hospitals in Lagos State, Nigeria.

Background: Indiscriminate disposal of hospital wastes including mercury/amalgam wastes pose a serious threat to life and environment. There is a growing concern about biomedical waste (BMW) management among health care workers, however there are limited reports on BMW management by dental personnel in developing countries.

Objectives: This study investigated the level of knowledge of BMW, observance of proper mercury hygiene and BMW management practice among public dental personnel in Lagos State, Nigeria.

Managing the phase-down of amalgam amongst Nigerian dental professionals and students: A national survey.

Background: Amalgam is one of the most reliable dental restorative materials. Health and environmental concerns associated with the mercury content of amalgam have necessitated an amalgam phase-down in clinical practice.

Objectives: This study investigated the level of awareness and preparedness for the planned amalgam phase-down recommended by the Minamata Convention amongst Nigerian dental students and dentists.

Amalgam phase down: baseline data preceding implementation in Nigeria.

Objective: The Minimata Convention on mercury includes amalgam phase-down and eventual phase-out from dentistry. To aid its subsequent evaluation it is important to have baseline data of amalgam use in a locality prior to implementing a phase-down.

Methodology: Records of patients spanning 5 years from January 2011 to January 2016 were analysed to determine and the compare frequency of amalgam usage with other dental materials for carious teeth restorations in a Nigerian university teaching hospital.

Comparison of the incidence of flare-up and time efficiency in single visit root canal treatment employing either rotary or manual step-back canal preparatory technique.

Aim: This study aims to compare the incidence of flare-up and operating time in root canal treatments where rotary or manual step-back canal preparatory technique was employed.

Materials And Methods: A randomised study was conducted in a Nigerian Teaching Hospital. One hundred and twenty teeth belonging to 95 patients were randomised into two (Rotary and Manual) groups.
