Dentifrice abrasiveness and brushing time may increase color change (∆E) and surface roughness (∆Ra) of resin composites. This study aimed to evaluate the effect of mechanical brushing time of dentifrices with different abrasiveness on ∆E and ∆Ra of nanofilled (Z350, 3M ESPE) and nanohybrid (Tetric N-Ceram, Ivoclar Vivadent) resin composites. Sixteen specimens (12 mm diameter x 2 mm thick) were...

Toothbrushing is fundamental to oral hygiene. Children differ in manual dexterity and their grip on toothbrushes. We videotaped toothbrushing sessions and observed the grip type, duration of brushing, and brushing technique used among 100 children aged 8-12 years. We then investigated the association between grip type and plaque removal, using plaque scores obtained at various time points. We f...

OBJECTIVE To determine the proportional distribution of endobronchial tuberculosis (EBTB) subtypes and to evaluate the types of bronchoscopic diagnostic procedures that can prove granulomatous inflammation. METHODS This was a retrospective study of 18 HIV-negative patients with biopsy-proven EBTB treated between 2010 and 2014. RESULTS The most common EBTB subtypes, as classified by the bron...

airway remodelling is characterized by the thickening and reorganization of the airways seen in mustard  lung patients. mustard lung is the  general description  for  the  chronic obstructive  pulmonary  disease induced  by  sulfur  mustard(sm). pulmonary  disease was diagnosed as the most important  disorder in individuals that had been exposed to sulfur mustard. sulfur mustard is a chemical w...

background: coverage of the bronchial stumps (bss) with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. there is no evidence for the application of human amnion allograft for prevention of air leak from the bs. the comparison of the amniotic membrane (am) and pleural patch for bs healing after lobectomy in dogs was our aim in this study. mate...

The use of toothbrushes has significantly improved oral hygiene. However, if brushing of the teeth is not done judiciously, it could result in severe trauma to the soft tissues of the oral cavity. This is particularly true in the young age group, since children tend to be very playful while brushing their teeth. This article describes the case report of a child who sustained a penetrating injur...
