All of us wish to have a pleasing and beautiful facial appearance. However, it also depends on the orientation of the teeth. Having crooked teeth, crowded teeth, and gaps between teeth are the common dental problems seen among many people. Some people also face problems like underbite and lower bite with differences in sizes of jaws. Dental braces can solve all these problems. However, there are many different types of braces. Here is a comparison of clear and metal braces.

Metal braces are available in stainless steel, silver, or gold colors. So, one can easily see your braces from a distance. Where as, clear braces are transparent. They are not visible and people will not know that you are having braces for teeth-straightening. Clear braces are mostly made of ceramic material which blend with the appearance of the teeth. They are, therefore, more preferably chosen for cosmetic considerations.

It is also thought that metal braces take much less time when compared to the clear ceramic braces to straighten the teeth. The maintenance of ceramic braces is considered to be much simple. Though the ceramic clear braces are designed with ceramic material, the ties required for them are made of metal. Cleaning these metal tiles of clear braces is difficult. The other comparison is of durability. Metal braces are more durable than the ceramic clear braces. Coming to cost, the traditional metal braces are more inexpensive when compared to the clear braces. Hence, have a view on the comparison of clear and metal braces before opting one for your treatment.

Pros and Cons of Ceramic Dental Braces

Are you distressed of your crooked or crowded teeth? Then it is a necessity for you to have dental braces to correct them. Ceramic braces are one of the options of different types of braces. Here are some pros and cons of ceramic dental braces.

Ceramic braces, as the name suggests, are made of ceramic or porcelain. So they blend well with the color of the teeth. Hence, they cannot be noticed from distance and even in photographs. Unlike metal braces, there are even less chances of irritation for your gums with ceramic braces. So, they are more comfortable than metal braces. They even do not get stained and hence, they maintain a natural look throughout the teeth-straightening process.

However, ceramic braces have to be worn for a longer time than the conventional braces. The ceramic material is much stronger than the stainless steel braces. Also, it is harder than the enamel of the tooth and hence, the enamel may be damaged when teeth touch the brackets or when the brackets are removed from the teeth. Maintenance of ceramic braces is also difficult. As they are larger than the metal braces, they are harder to clean resulting in hygienic problems. Though they do not get stained, the clear elastic ties which are used to hold the arch wire to the bracket get stained. It is not possible to clean the stained ties. They only need to be replaced. Also, the ceramic material may chip or break as it is brittle. Hence, consider the pros and cons of ceramic dental braces when deciding to have dental braces.

Know About Database Vs Data Warehouse

Database used by the companies to organize, store, and retrieve large amounts of data easily. Online transaction processing (OLTP) is supported by traditional databases which includes insertions, deletions, updates and also supports information query requirements.

A data warehouse helps in collecting and managing of data which helps management in decision making. It preforms functions in three stages – staging, integration and access. It helps in easy retrieval and analysis of data. It provides clean, transformed and cataloged data.

The main difference between database and the data warehouse is that the database is designed to record the data and the data warehouse is designed to respond to analysis questions that are critical for the business. Application databases are On Line Transaction Processing (OLTP) systems where every transaction has to be recorded. Where as data warehouse is a database that is designed for facilitating querying and analysis.

Creation of a DW leads to a direct increase in quality of analysis as the table structures are simpler, standardized and de normalized.
