Evaluating the Sealing Performance of Endodontic Sealers: Insights Into Achieving Complete Sealing.

Background The importance of achieving optimal sealing in endodontic procedures cannot be overstated, as it directly influences the success and durability of root canal treatments. The objective of this research was to measure and identify the sealing ability of endodontic sealers by evaluating their adhesion to root canal dentin and the extent to which they achieve a complete seal. Methods A total of 60 extracted lower premolar teeth were randomly divided into three groups of 20 samples each.

Comparative Assessment of Working Length Determination: Apex Locators versus Endomotor with Built-in Apex Locator in Single-Rooted Permanent Teeth.

Aim: To compare the effectiveness of Apex Locators and Endomotor with built-in Apex Locators for determining the working length in root canal treatment.

Methods: A total of 120 patients were randomly assigned to three groups: Group 1 (Root ZX Mini Apex Locator), Group 2 (Minipex Apex Locator), and Group 3 (Endopilot Endomotor with built-in Apex Locator). Working length was determined using respective devices, followed by canal preparation and radiographic confirmation with a master cone.

Salivary α-amylase as a stress biomarker in mentally and physically disabled individuals during COVID-19 times.

Background: Stress is faced by every individual in their day-to-day life activities. During pandemic, most people have experienced multiple episodes of depression, anxiety, and insomnia. Several medical and dental problems are reported with stress and the fastest and easiest way to study and investigate is through body fluids, mainly saliva.

Life span of Neoendo Flex and ProTaper Next rotary files with reciprocating motion in single-rooted teeth.

Background: Cleaning and shaping represent a vital step in the endodontic procedure. In routine endodontic therapy, the fracture of nickel-titanium (NiTi) instruments is a procedural problem creating a major obstacle to therapy.

Aim: This study examines the life span of one Neoendo Flex and ProTaper Next (PTN) rotary file using reciprocating motion and compares the time required by both file systems for canal preparation.

Assessment of various endodontic instrumentation systems on the amount of apically extruded bacteria - An study.

Aim: The objective of this study was to assess the effect of different endodontic instrumentation systems on the amount of apically extruded bacteria.

Materials And Methods: One hundred and twenty freshly extracted human mandibular premolars with single canal were collected. Endodontic access cavities were prepared and then contaminated with an suspension (ATCC 29212).

Clinical and radiographic assessment of periapical pathology in single versus multivisit root canal treatment: An study.

Objective: The objective of the study was to compare and evaluate the clinical and radiographic outcome of single- versus multivisit endodontic treatment in teeth with periapical pathology at the end of 1, 3, and 6 months.

Materials And Methods: Sixty single- and multi-rooted teeth indicated for root canal treatment with periapical pathology were included in the study. The teeth were assigned randomly into two groups Group I and Group II ( = 30 each), which were further subdivided into subgroup IA, subgroup IB and subgroup IIA, subgroup IIB ( = 15 each), respectively.

A Rare Case of Vanishing Lung Syndrome.

Vanishing lung syndrome (VLS) is a rare radiological syndrome in which the lungs appear to be disappearing on X-ray. It is a chronic, progressive condition usually affecting young male smokers and is characterised by giant emphysematous bullae, which commonly develop in the upper lobes. We describe here a rare case of 60-year-old male patient who had a history of chronic smoking for 30 years.

Osteoblastic and osteoclastic metastases in a single vertebra-a rare presentation.

Malignancies may produce bony metastases which may be osteoclastic or osteoblastic. Vertebrae are a common site for bony metastases. Prostatic adenocarcinoma is an important source of vertebral metastases that are mainly osteoblastic in nature.
