OBJECTIVE The present study was designed to test the null hypothesis that there is no significant difference in debridement quality promoted by 3 nickel-titanium (NiTi) rotary systems. STUDY DESIGN Sixty-seven vital mandibular molars that were prospectively collected in vivo were used. The teeth were extracted and then pulp tissue fixed by 10% formalin. The use of different NiTi rotary system...

PURPOSE Meniscal debridement with an arthroscopic radiofrequency (RF) wand versus an arthroscopic shaver and their comparative effects on menisci and underlying articular cartilage were studied. METHODS When repair is not feasible, degenerative or post-traumatic meniscal tears often need debridement. Six fresh bovine knees were harvested, the tibial plateau was dissected free from the femoral...

Odontogenic cutaneous sinus tracts (OCSTs) are generally primarily misdiagnosed and inappropriately treated by virtue of their rarity and the absence of dental symptoms. Accurate diagnosis and treatment and the elimination of the source of infection can reduce the incidence of complications and relieve the pain of the patient.In this case report, we present the case of an 11-year-old patient wi...

Glide path is a procedure that precedes mechanical instrumentation of the root canals. It defined as used to expand or create smooth tunnel from coronal part canal its physiological terminus. performed using small sized hand files specially designed NiTi instruments. An adequately created glide extends life rotary instruments, enables better and chemical debridement easier preservation original...

introduction: periodontal diseases are considered as some of the most common reasons of teeth loss, which occur due to the aggregation of microbial plaque and other precipitations on the dental surfaces . in this study, the scaling effect using manual tools, ultrasonic machine and erbium-doped yttrium aluminum garnet (er:yag)laser on the connection of the human gums connective tissue cells on t...

Background: The key reason for failure of an endodontic treatment is incomplete debridement and sterilization because of complex root canal system anatomy which makes elimination of micro-organisms difficult. In spite of the chemical and mechanical debridement of root canals, studies have reported that some microbes like Enterococcus faecalis thrive in periapical lesions, triggering a failure o...

root morphological and distribution responses of signal grass (brachiaria decumbens) to long-term cattle grazing were examined in a tropical pasture in malaysia. the treatments were no grazing by cattle and grazing at a moderate stocking density (2.7 animal unit/ha) under rotational grazing for 33 years. the method consists of taking soil core using a soil corer to a depth of 30 cm and extracti...

background: multi drug resistant (mdr) pseudomonas and acinetobacter species are defined as resistant to at least three classes of antibiotics. most studies have demonstrated that mdr gram negative infections convey increased mortality and morbidity. case: an 11-year –old girl was admitted to pediatric burns unit with burn injury of approximately 68% total body surface area (tbsa). discussion: ...
