Although bracket pools in the NCAA Men’s Basketball Tournament are a game, practice most players do not compete strategically. Instead, they more likely to choose brackets as though playing lottery. When faced with such unsophisticated opponents, game simplifies finance problem where you must an optimal portfolio of brackets. The that pay highest return modal which higher seeds always...

OBJECTIVE To evaluate the shear bond strength of precoated orthodontic brackets bonded with self-etching primer relative to that of noncoated conventionally-bonded brackets at two different time intervals. METHODS Twenty-one subjects were selected for randomized split-mouth bonding of two types of brackets to the maxillary arch. Half of the teeth had precoated brackets bonded using self-etchi...

Orthodontic treatment with fixed appliances is considered a risk factor for the development of white spot caries lesions (WSL). Traditionally, brackets are bonded to the buccal surfaces. Lingual brackets are developing rapidly and have become more readily available. Buccal surfaces are considered to be more caries prone than lingual surfaces. Furthermore, lingual brackets are shaped to fit the ...

We describe an p-mechanical (see funct-an/9405002 and quantph/9610016) brackets which generate quantum (commutator) and classic (Poisson) brackets in corresponding representations of the Heisenberg group. We do not use any kind of semiclassic approximation or limiting procedures for ~ → 0.

BACKGROUND Orthodontists are commonly faced with the decision of what to do with debonded or inaccurately positioned brackets. An economical option to this dilemma is to recycle the brackets. Many recycling methods have been proposed, but the optimal bond strength of these recycled brackets needs further evaluation. Objectives: To evaluate and compare the effect of three recycling methods: (i) ...

Amaç: Tonsillektomi cerrahisi, Kulak Burun Boğaz (KBB) pratiğinde en sık yapılan cerrahi işlemlerden biridir. Ameliyat sırasında cerrahın görüş alanını arttırmak için kullanılan ağız açacağı ve dil basacağı, hastanın dokusuna yüksek basınç uygulayarak çeşitli komplikasyonlara neden olabilir. Bu çalışmanın amacı, tonsillektomi erişkin hastalarda, esnasında basacağının üzerinde oluşturduğu basınc...

BACKGROUND The orthodontist seeks an archwire-bracket combination that has both good biocompatibility and low friction. Hence, the aim of this multicenter in vitro study was to evaluate and compare the frictional resistance generated between titanium (Ti), stainless steel (SS), ceramic and ceramic with metal insert (CMI) brackets with SS wires of varying dimensions in a specially designed appar...

INTRODUCTION The aim of this in-vitro study was to evaluate the frictional forces generated by various combinations of brackets and orthodontic wires by using an experimental model with 3 nonleveled brackets to gain a better understanding of the resistance to sliding during dental alignment and leveling. METHODS Two kinds of orthodontic brackets were tested: passive self-ligating brackets and...
