To build jQuery, you need to have the latest Node.js/npm and git 1.7 or later. Earlier versions might work, but are not supported. For Windows, you have to download and install git and Node.js. OS X users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js. Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Easy-peasy. Special builds can be created that exclude subsets of jQuery functionality. This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used. For example, an app that only used JSONP for $.ajax() and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules. Any module may be excluded except for core, and selector. To exclude a module, pass its path relative to the src folder (without the .js extension). Some example modules that can be excluded are: Note: Excluding Sizzle will also exclude all jQuery selector extensions (such as effects/animatedSelector and css/hiddenVisibleSelectors). The build process shows a message for each dependent module it excludes or includes. As an option, you can set the module name for jQuery's AMD definition. By default, it is set to "jquery", which plays nicely with plugins and third-party libraries, but there may be cases where you'd like to change this. Simply set the "amd" option: For questions or requests regarding custom builds, please start a thread on the Developing jQuery Core section of the forum. Due to the combinatorics and custom nature of these builds, they are not regularly tested in jQuery's unit test process. The non-Sizzle selector engine currently does not pass unit tests because it is missing too much essential functionality.

Crowns and Bridges

Home Crowns and Bridges


A crown, sometimes known as dental cap, is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth.

Crowns are indicated to:

  • Replace existing crowns which have failed.
  • Restore the form, function and appearance of badly broken down, wornor fractured teeth, where other simpler forms of restorations are unsuitable or have been found to fail clinically.
  • Improve the aesthetics of unsightly teeth which cannot be managed by simpler cosmetic and restorative procedures.
  • Maintain the structural stability and reduce the risk of fractures of extensively restored teeth including those which have been endodontically
  • Restore the visible portion of a single dental implant.

dental crown is a fixed prosthetic “cap” that fits over a damaged tooth and restores it to its normal appearance and function. It can be molded from several different materials, including ceramics, porcelain-and-metal, gold, and resin

To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth. To restore an already broken tooth or a tooth that has been severely worn down. To cover and support a tooth with a large filling when there isn’t a lot of tooth left.

Typically, dental crowns tend to last between five and 15 years, with some crowns even lasting up to 25 or 30 years.
