Purpose: The purpose of this study was to evaluate the profile of pediatric oral lesions in northeastern Brazil.
Methods: Biopsy records of oral lesions were retrieved from patients aged zero to 18 years who were treated over 18 years in two university hospitals in northeastern Brazil. Routine pathological sections were re-examined and classified into six groups: (1) odontogenic and nonodontogenic cysts; (2) odontogenic tumors; (3) salivary gland pathology; (4) nonodontogenic tumors and tumor-like lesions; (5) bone pathology; and (6) miscellaneous.
Pemetrexed is a novel, multitargeted antifolate approved for the treatment of malignant pleural mesothelioma and non-small cell lung cancer. Although pemetrexed is a safe drug, some adverse effects such as myelosupression and cutaneous reactions are observed. Pemetrexed-induced eyelid edema is a rare side effect of pemetrexed treatment, and until this moment few cases were reported in the medical literature.

Methods: Forty bovine teeth were abraded with the air abrasion system Mach 4.1 for 10 and 15 seconds, employing conventional and sonic tips of 0.
Objectives: To evaluate the influence of the grain size coating and shaft angulation of ultrasonic and high-speed diamond burs on the dental cutting effectiveness.
Materials And Methods: For the grain size evaluation, cavities were prepared on 40 incisors using high-speed (1092 and 1093F KG Sorensen(®)) and ultrasonic tips (8.2142 and 6.
Unlabelled: Staphylococcus aureus strains can be disseminated during dental treatment and occasionally lead to contamination and infection of patients and dentists. THE OBJECTIVE of this study was to determine the frequency and compare the number of S. aureus colonies isolated from the nose, hands and tongue of students and patients, as well as from the clinical environment, before and after dental treatment.

Study Design: Cavities were randomly prepared in 160 specimens (noncarious and artificial carious dentin) by high-speed diamond tips (KG Sorensen 1013), air abrasion system (Prepstart, Danville Engineering), ultrasonic tip (CVDentus 8.3231-1), and ultrasonic tip associated with ultrasonic cavitation by water for 10 s.
