OBJECTIVE
This study aimed to examine changes in physical symptom severity, functional status, supportive care needs, and related factors in oral cavity cancer patients during 6 months after beginning radiation therapy (RT) or concurrent chemotherapy and radiation therapy (CCRT).
METHODS
A
OBJECTIVE
The aim of the study was to evaluate the influence of different posts and types of cementation on the fracture load and fracture mode of crowned, endodontically treated premolars with class II cavities in an ex vivo setting.
METHODS
Forty-eight single-rooted human premolars were
The aim of this in vitro study was to compare quasistatic and cyclic fatigue dentin bond strength of modern adhesive systems representing different generations. One hundred and fifty cavities were made in discs of freshly extracted human third molars and filled with direct resin composite
This study was designed to determine whether the mechanical cyclic stressing that occurs during normal mastication contributes to margin breakdown of dental amalgam restorations. The method used appears to duplicate the mechanical stresses developed in vivo during mastication, as the result of tooth
Carbohydrate (CHO) mouth rinse has been shown to improve endurance performance and maintain the central drive of contracting muscles. Salt (NaCl) mouth rinse solution, often used in dentistry to desensitise the oral cavity to pain, could also activate cortical areas of the brain. Hence, the
This study evaluated the microleakage of resin-modified glass ionomer, flowable compomer and flowable resin composite restorations on a Class V cavity of simulated advanced root caries under a flexural load cycling condition. Thirty-six non-carious human maxillary premolars were mounted in
This in vitro study evaluated the marginal microleakage of composite inlays luted with 3 different cement systems. The null hypothesis was that the luting materials would not influence dye penetration, showing the same degree of microleakage. Thirty-six sound molars were selected,
OBJECTIVE
The purpose of this study was to evaluate the effects of filler level on the fatigue impact resistance of resin composite.
METHODS
A series of experimental composite materials was prepared by incorporating a silanized quartz filler (3-5 microns in size) into a light-cured resin matrix of
Radiation-related caries (RRC) is a disease with a high potential for destruction of the dentition, which impairs quality of life in head-and-neck (HN) cancer (HNC) patients who undergo radiotherapy. In light of the recently described "clustering of oral symptoms theory," the present
Background: This study aims to compare the percentage of dentin removed, instrumentation efficacy, root canal filling and load at fracture between contracted endodontic cavities, and traditional endodontic cavities on root canal therapy
The effect of pre-treatment of composite inlays on bonding performance between a resin composite inlay and a luting composite has not been fully studied. The aim of the present study was to evaluate the influence of three different pre-treatment modes on fatigue bond strength and marginal
We studied predictors of the closure of tuberculosis infiltrate decay cavities (DC) in the affected regions in patients with infiltrative lung tuberculosis (ILT) by clinical examination. X-ray laboratory and psychological methods 103 patients were under observation for 12 months and received
A 74-year-old woman was admitted to our hospital with the complaint of general fatigue. Chest X-ray revealed multiple thin-walled cavities in both lung fields. Cystadenocarcinoma in the liver and secondary lung cancer were diagnosed on the basis of chest X-ray, abdominal CT, and lung biopsy. She
Women diagnosed with stage III or IV ovarian cancer typically are treated with surgery followed by chemotherapy. Intraperitoneal (IP) chemotherapy, the direct administration of chemotherapy into the IP cavity, has been explored as a viable treatment option for some women with advanced ovarian
OBJECTIVE
To determine whether there is an optimal level of pressure support ventilation (PSV) for recovery from acute diaphragmatic fatigue.
METHODS
Prospective laboratory trial.
METHODS
Experimental laboratory.
METHODS
Twenty healthy adult New Zealand White rabbits.
