Evaluating periodontal probing depth and furcation involvement on the endodontic treatment of maxillary fourth premolar complicated crown-root fractures in 122 teeth.

Objective: This study aimed to evaluate the prognosis of root canal treatment (RCT) in dogs with complicated crown-root fractures (CCRFs) of the maxillary fourth premolar (PM4), focusing on the impact of periodontal probing depth (PPD) and furcation involvement on treatment outcomes.

Methods: The study analyzed 122 PM4 teeth affected by CCRF in dogs. The primary outcomes were the success rates of RCT, measured against PPD, and the degree of furcation involvement (stages F0, F1, and F2).

Oxidative Stress Is a Key Modulator in the Development of Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide, and scientific studies consistently report that NAFLD development can be accelerated by oxidative stress. Oxidative stress can induce the progression of NAFLD to NASH by stimulating Kupffer cells, hepatic stellate cells, and hepatocytes. Therefore, studies are underway to identify the role of antioxidants in the treatment of NAFLD.

Arthroscopic detection of medial meniscal injury with the use of a joint distractor in small-breed dogs.

The goal of the present study was to evaluate the diagnostic value of a joint distractor in arthroscopy in small-breed dogs. Sixty stifle joints, which were collected from thirty cadavers, were used in this study. To simulate different injuries, no medial meniscal tear, a full-thickness vertical longitudinal tear, a partial-thickness vertical longitudinal tear, full- and partial-thickness vertical longitudinal tears, or a peripheral detachment were created on the caudal horn of the medial meniscus of each stifle joint along with rupture of the cranial cruciate ligament.

Evaluation of a Veress needle for the fluid egress system of stifle arthroscopy in toy dog breeds.

Objectives: The aim of this study was to evaluate the use of a Veress needle as a fluid egress system for stifle arthroscopy in toy dog breeds.

Methods: Cadaveric canine stifle joints (n = 32) were prepared to induce an artificial intra-articular haemorrhagic effect, followed by stifle arthroscopy. The stifles were randomly assigned to one of three groups, and a fluid egress portal was established using a Veress needle (VN), a standard egress cannula (SE), or an intravenous catheter stylet (CS).

Total hip replacement in two dogs with unsuccessful femoral head ostectomy.

An English setter (case 1) and a Tibetan mastiff (case 2) presented with intermittent weight-bearing lameness on the right hind limb when trotting. The dogs had a history of femoral head and neck ostectomy (FHNO). Orthopedic examination revealed pain and crepitus on the right hip joint.

Using stable isotope analysis to discriminate gasoline on the basis of its origin.

Rationale: Leakage of gasoline and diesel from underground tanks has led to a severe environmental problem in many countries. Tracing the production origin of gasoline and diesel is required to enable the development of dispute resolution and appropriate remediation strategies for the oil-contaminated sites.

Methods: We investigated the bulk and compound-specific isotopic compositions of gasoline produced by four oil companies in South Korea: S-Oil, SK, GS and Hyundai.
