INTRODUCTION A triple antibiotic mixture of ciprofloxacin, metronidazole, and minocycline was used as an intracanal medicament in an attempt to disinfect the root canal system for revascularization of a tooth with a necrotic pulp. However, discoloration developed after applying the triple antibiotic mixture. METHODS Six weeks after a triple antibiotic paste had been applied to the root canal ...

Counterfactual thought and talk play a central role throughout science and in many areas of philosophy. Hence it’s not surprising that they have been extensively studied in a number fields: besides philosophy itself, linguistics, psychology, and computer science. In particular, much work has gone into developing a logic and a semantics for counterfactual conditionals, i.e. conditionals of the f...

Subungual melanoma with pigmentation beneath the nail that extends to involve the proximal nail fold is referred to as Hutchinson's sign. Black or brown subungual discoloration involving the proximal nail fold secondary to other etiologies has been referred to as pseudo-Hutchinson's sign. Three patients with nail discoloration and concurrent dyschromia of the proximal nail fold are described: a...

There is concern that bluish skin discoloration associated with ezogabine treatment could be permanent. We present a case of ezogabine-induced skin discoloration that resolved completely after discontinuation. A 55-year-old woman started ezogabine 400 mg three times a day at age 41. Bluish pigmentation over the toe nails, finger nails, around eyes and over and around lips was first noted after ...

The rise of causality and the attendant graph-theoretic modeling tools in the study of counterfactual reasoning has had resounding effects in many areas of cognitive science, but it has thus far not permeated the mainstream in linguistic theory to a comparable degree. In this paper I show that a version of the predominant framework for the formal semantic analysis of conditionals, Kratzer-style...

Tooth colour has esthetic importance since it is visible during speech and smile. It plays a major role in overall smile of an individual. This review discusses the various causes of tooth discoloration.

(See [2] for a basic de nition.) The TPP property for the triple (S, T, U) is invariant under permutations of the triple, that is, the permuted triples (S,U, T ), (T, S, U), (T,U, S), (U, S, T ), (U, T, S) all satisfy the TPP i (S, T, U) satis es the TPP, ([6], p. 45). We denote by =(G) the set of all TPP triples of G, and by =(G)/Sym3 the set of equivalence classes of =(G) under the equivalenc...

We present a new lexical resource for the study of preposition behavior, the Pattern Dictionary of English Prepositions (PDEP). This dictionary, which follows principles laid out in Hanks’ theory of norms and exploitations, is linked to 81,509 sentences for 304 prepositions, which have been made available under The Preposition Project (TPP). Notably, 47,285 sentences, initially untagged, provid...

Superficial transient discoloration of the dorsum of the tongue may be caused by some foods, beverages and drugs (such as iron salts, bismuth, chlorhexidine, lansoprazole, amoxicillin, clarithromycin). When such discoloration noticeably affects the posterior dorsum of the tongue with longer filiform papillae and stained dark brown or black, the term ‘black hairy tongue’ is used. Black tongue (l...
