Want to Know About Types of Teeth and Their Functioning?

Teeth help us to break, chew and digest the food particles, teeth play an important role in speech, giving smile and impact our overall health. Humans have two sets of teeth, one is primary and the other is permanent ones. Teeth begin developing in uterus, or during pregnancy. A set of 20 “milk teeth” will be there until the age of six. In the second set, humans develop 32 permanent teeth which consist of four different types. Each type of tooth has its own shape and performs a different work. Incisors, canines, premolars and molars are the four types of teeth.

The incisors are located in the front and the center of the mouth. Eight teeth (two sets of four teeth i.e., 4 in the upper and the 4 in the lower jaws) that have horizontal and sharp edges are used for biting and cutting of the food particles.

The canines are located on each side to the incisors. Four canine teeth are there which is also known as cuspids and one in each quadrant of the upper and lower jaw. These are the sharpest, stronger and larger and are used for ripping,tearing, shredding and piercing motions.

The premolars are also known as bicuspids and are located behind the canine teeth. Total eight premolars are there. Two premolar teeth are there behind each side of the canine teeth in the upper and lower jaw. These are used for chewing and grinding of food.

The molars a type of teeth with a flattened surface are used for final chewing, crushing and grinding food before swallowing. Most of the chewing occurs in the back of the jaw by the molar teeth. Three molars in each quadrant of the jaw, with a combined total of 12 are present in humans. The molars have numbered names according to their location: first molars are adjacent to second premolars towards the back of the mouth, with second and third molars following consecutively. The third molars are often called the wisdom teeth. read more…

Porcelain Filling Dentistry and Their Benefits

Porcelain filling filling in dentistry aims to restore and the natural look and fill the deficit of teeth.

Porcelain filling even advantageous over composite fillings, and are durable, stronger and natural looking. Earlier, porcelain filling was used only for front teeth but now this is used almost in all the areas of preparing the fillings like inlays, outlays and crowns. This filling uses advanced technologies, which makes the resin harden the surface of the teeth so that they look natural and healthy.

This treatment is similar to the traditional filling methods and requires at least two visits to the dentists to get ready for the filling. Porcelain is a glass material composed of oxygen and the silicon and these are better than composite because teeth don’t get stained, or you don’t have any dis-coloration problems as is in case composite filling.

How the treatment is done?
As it takes at least two visits to the dentist in first visit the dentist will drill the area which is infected with cavities then takes the impressions of teeth and then fills it with temporary fillings so that you will be comfortable for second visit. Now the impressions that is taken will be sent to the lab by the dentist to get the customized porcelain fillings. After the dentist receives the fillings he/she will bond the fillings on your teeth where drilling is done on the second visit. This is how the treatment is carried out.

Benefits of porcelain fillings
Both porcelain and composite fillings bring benefits to the patients. But porcelain filling has added advantages when compared to composite fillings. Some of them are:

  • These filling is more durable when compared to all other cavity fillings – nearly 30 years that no other cavity fillings can replace this fillings in this point. All other fillings last 7-10 years.
  • Porcelain fillings bond the teeth easily and get strengthened as it doesn’t require more tooth structure to be removed.
  • They give a more natural look than all other fillings do and don’t make you appear as if you have fillings in your mouth. With this, you fill have a great look and smile with your teeth.
  • This fillings don’t get stained or discolored as composite fillings.

With these major advantages, over all other fillings, you can opt for porcelain fillings compared to all other fillings today even if the filling is costlier when compared to metal fillings. They will save the money in future if you invest some more now. So, you don’t have to worry with this filling as they give you long term benefits.

Zoom Advanced Power Teeth Whitening Treatment

Zoom power whitening is a process of bleaching the dis-colored enamel and dentin. This treatment is mostly used for the complete makeover of the teeth.

Reasons for zoom power whitening:
The major reasons for the treatment are:

  • Dis-coloration of teeth due to eating and drinking habits
  • Smoking is one more factor that leads to zoom power whitening
  • Aging may also cause the teeth dis-coloration
  • Chewing of tobacco
  • Anti-biotics and excessive usage of fluoride may cause tooth dis-coloration
  • Consumption of alcohol also leads to zoom power whitening

How zoom power whitening is performed?
Zoom power whitening can be done in only one visit and it takes only couple of hours to complete the treatment. It is simple method. Dentist first covers gums and lips leaving the teeth. Now, zoom hydrogen peroxide whitening gel is applied along with the zoom light. This will penetrate through the teeth and removes stains and dis-coloration. After zoom light is activated the gel remains their for 15 minutes. At last fluoride paste-gel is applied for teeth. It is less sensitive method than other teeth whitening methods and it is also a painless treatment.

This treatment is completely safe and efficient but their would be a chance of minor problems like irritation and sensitivity but only 25% which is avoided by post treatment. This treatment is not recommended for the children under the age of 13 years, pregnancy and lactating women.

Evolution of Electronics : Strolls, Strides and Leaps

Electronics deals with electrical circuits that use active power devices like diodes & transistors and passive links to make the active components work. Electronics is credited with the fast transformation of technology and world in the industrial era. Electronics has evolved from a very premature and crude stage to a well advanced and sophisticated stage over the years. This development has been achieved in different stages over the years and not in a short span of time.

History
With the discovery of electricity, large scale production of electric power led to the emergence of the electronics. The early electronics consisted of simple applications like telegraphy and gramophone only. The invention of vacuum tubes benefited the electronic industry. This led to the invention of gadgets and instruments like radios and other important devices. Since those days, major changes have taken place in technology keeping them in track with the needs of the consumer and the industry.

Moore’s law
Moore’s law is based on the observation of the fact that the number of transistors in a dense electronic integrated circuit will become double in approximately every two years. The law has held its credibility over the years and the development of the electronic devices is in accordance with the law that Gordon E. Moore gave in 1965.

First generation – vacuum tubes
The first generation of the electronics developed during 1945-1955. This era was remarkable due to invention vacuum tubes.
These tubes achieved the control of current in vacuum by controlling the emission of electrons from filaments. Depending upon the method used to isolate electrons from the filament, they were called photo electrons, thermal electrons, etc. The vacuum tubes could be used as switches and amplifiers based on the application.

The vacuum tubes were classified based on the number of electrodes as follows:

  • Diodes
  • Triodes
  • Tetrode
  • Pentode

The structures were bulky and generated a lot of heat occasionally, which sometimes hindered the expected performance of the device. Therefore, bulky heat sinks had to be used. In addition to that they were prone to regular wear and tear. Therefore, they had to be replaced periodically. The problem of arcing between the electrodes was yet another problem. With the invention of transistors, the vacuum tubes became a thing of past.

Second generation- transistors
The second generation is marked with the invention and rise of transistors. With the benefits of small size, better heat dissipation capabilities, reliability and speed of operation, they took over the place of of vacuum tubes in electronics.
Transistors are basically semiconductor solid state devices having three terminals or regions doped in different concentrations. Emitter is used to provide the supply and collector is used to collect it. The base was responsible for the switching action of the transistor. Hence transistor can act in two modes viz as a switch or as an amplifier.

They were having a few minor drawbacks of heat resistant capabilities and their limitation to high frequency applications.

Third generation-integrated circuits
The third generation transistors led to the development and usage of Integrated Circuits (IC). An IC was generally fabricated by embedding a large number of transistors in a small place. Starting with small scale integration (SSI), the technology rose to the heights of Very-large-scale integration (VLSI, ULSI) and 3D-IC. It led to the inventions of multiple electronic innovations like microprocessors and micro-controllers, which revolutionized the field of computer manufacture.

  • SSI (Small Scale Integration) : 10s of logic gates or transistors. Eg: Plessei SL201
  • MSI (Medium Scale Integration) : 100s of transistors on a chip.
  • LSI (Large Scale Integration) : 1000s of transistors per chip
  • VLSI (Very Large Scale Integration) : 100s of 1000s of transistors on a single chip.
  • ULSI (Ultra Large Scale Integration) : more than one million transistors.
  • WSI (Wafer Scale Integration) : The entire silicon wafer is embedded with a very large integrated circuit on a single chip called “super-chip” primarily meant for parallel supercomputing.
  • SOC (System on chip): It is the fabrication of the entire circuitry required for a system on a single chip. Very complex and costly process and risky also.
  • 3D-IC (Three dimensional integrated circuit): The electronic components are arranged horizontally as well as vertically in different layers. The communication between the layers takes place through die signaling or through small wire links.

The invention of microprocessors and micro-controllers provided extra heights to the electronic industry with improved computers and automation.

Artificial intelligence – a step ahead
This technology is aimed at providing human like thinking capabilities to machinery. Micro-controllers are programmed directing the system to perform in a particular manner depending upon the feedback from the parameters. Artificial Intelligence aims at creating a machinery and electronics, which have the capability to take independent and situation based decisions and act accordingly as humans do creating a race for “Intelligent Machines”.

Artificial intelligence is based on the pillars of perception, reasoning, planning and learning. Research is going on to get a better grasp of the technology so that it could be used for the benefit of all.

The working Mechanism of the Power Steering

Power steering is an advanced version of the usual mechanical steering mechanism. It helps the driver in maximizing the steering effort put on the steering wheel. With an increased power, power steering mechanisms add extra sensitivity and the driver is able to make very precise turns with little effort. A power steering mechanism can use either hydraulics or electric actuators to do this.

Components of a hydraulic power steering mechanism

Rotary-Vane-Pump
The hydraulic power for the steering is provided by the rotary vane pump. This pump is run by a belt from the engine. It contains a number of vanes arranged around its axis. These vanes draw hydraulic fluid from the reservoir and force it through the outlet tube at high pressure. When the vehicle is traveling at high speeds, steering speed also should be more. To facilitate this, the vane pump is connected to the engine, when the engine spins at higher speeds so that the pump also works fast. To avoid too much pressure in the pump at high speeds, there is also a relieve valve in case too much of fluid is pumped to remove.

Rotary valve
The rotary valve is a device that channels hydraulic fluid into the steering gear. It controls the fluid flow that is directly involved in steering. The rotary valve is designed in such a way that it influences steering only when the driver is steering. Otherwise, the rotary valve performs no function. The input shaft from the steering wheel fits into the upper part of the rotary valve and it leads to the torsion bar.

Spool valve assembly
The spool valve assembly attaches to the driving shaft and it leads to the torsion bar. The spool valve is the component that lets hydraulic fluid to flow in specific levels to turn the steering gear. There are two kinds of valves, the inner valve and the outer valve.

Steering gear:
The steering gear receives the hydraulic fluid and rotates the pinion or the worm gear.

Working:
As the steering shaft is rotated, it turns the torsion bar in the rotary valve in the same direction. Since the rotary pump is already running, there is hydraulic fluid supply to the rotary valve. The inside of the rotary valve, that is, the spool valve assembly rotates in the same direction as that of the torsion bar letting hydraulic fluid pass through them in a single direction. This rotates the outer valve and the outer valve steers the steering gear. When the direction of steering is changed, the torsion bar turns in the opposite direction, making the hydraulic fluid flow in the opposite direction. When there is no steering, the outer valve remains closed, and there is no flow of hydraulic fluid into the spool assembly.

Know all About Enamel Shaping

Dental Implant LondonEnamel shaping is nothing but re-shaping the uneven teeth and the rough teeth to give them a better shape as the normal teeth. This is a simple procedure when compared to dental braces or crowns.

Enamel shaping can be done quickly and the results can be achieved in minutes. It is a comfortable procedure that any one can take. During enamel shaping only the small portion of the teeth which is rough or uneven is removed for re-construction to give a uniform shape. As simple the treatment, it is also cost effective.

Who needs enamel shaping?
Dental implants LondonPeople who have problems mentioned below require enamel shaping:

  • People with uneven teeth
  • Cracked or chipped teeth
  • Having flaws in the teeth surface
  • Overcrowding which is minor
  • People who have long teeth

How enamel shaping is done:
Marylebone dental practiceAs it is a simple process, it doesn’t take much time and results are obtained fast. Enamel shaping doesn’t cause pain. It is done in one sitting.

The dentist at first will check the condition of the teeth and polishes the teeth using some tools, removes the uneven surfaces of the teeth without giving anesthesia.

Enamel shaping is a permanent procedure and lasts for long time unless proper care is taken and regular dental check ups are made.

Dentist EalingSide effects of enamel shaping:
The procedure of doing enamel shaping is simple and long lasting, and doesn’t cause pain. As only some amount of enamel is removed from the teeth there are long term consequences caused by it. If more amount of enamel is removed from the teeth then the dentine gets exposed which may cause sensitivity problem. Generally only damaged or uneven part of the enamel is removed. So, there won’t be any problem with enamel shaping.

Benefits of enamel shaping along with dental bonding:
Along with enamel shaping you can get dental bonding if there are any holes and gaps in between your teeth. This is opposite to enamel shaping. Many dentists combine this procedure to give a perfect shape and flawless surface to your teeth. You may get the benefits of both the treatments at once.

Know about Open and Limited Slip Differential

It is important for you to know that not all the wheels of your car spin at the same speed when it is moving. This is because the inside of the wheels needs to travel a shorter distance than the outside wheels need to during the turning. This is so both in front as well as rear wheels.

Open slip differential
This poses a problem because the wheels that receive power from the engine and spin are designed to turn the same way. It is the differential (a set of gears) overcomes this problem by transferring torque to both the wheels and at the same time allowing them to rotate at different speeds. The differential commonly used in two wheel drive vehicles is open slip differential.

This design of enabling the wheels to spin at different speeds functions very well at surfaces which have good amount of traction, but in surfaces like ice or lose gravel, they have crucial disadvantages. Imagine one of the driving wheels of a vehicle moving over a patch of snow, and the others moving over a normal surface. In such a situation, the differential would direct all the torque towards the wheel that offers the least resistance, and in this case, the wheel is moving on snow. Thus, one of the wheels gets more torque than needed and this results in slippage. Getting back to normal movement in such cases would not be possible until both of the wheels start to get enough traction from the surface.

To enable the rear and the front axle spin at different speeds, a differential is introduced in between them, in addition to the two right-left differentials already present. Thus, drive train binding is avoided. But there is still the problem caused by the nature of open differential. That is, the slippage caused by the differential putting extra torque on the wheel offering least resistance.

However, both four-wheel drive and all wheel drive, overcome such problems by other kinds of differentials or devices that prevent from slippage.

Limited slip differential
Limited slip differentials are very much like open differentials, in that they allow for wheels to spin at varying speeds. Limited slip differentials have a spring pack and a set of clutches. When the wheels move in a straight line, there is no real use of the clutch. When there is a requirement for one wheel to spin faster than the other, the clutches come into action. For the wheels to spin at varying speeds, they must first overpower the clutch. When in a snow patch, if on wheel tries to spin faster than the other, the clutch would try to disallow it. The physical strength of the spring and the friction induced by the clutch determine how much force is needed for the wheel to spin at differing speeds. In a condition like snow, the clutch would overpower differential rotation of any wheel, because there is not much pressure on the clutch and the spring. But in conditions like taking a turn, due to the traction offered by the surface, the wheels overcome he clutch and spin at different speeds.

The Working and Maintenance of a Glow-Plug

The glow plug is a device used for assisting the engine in starting by heating it. It is a pencil like structure which has a heating element at the tip. When it is electrified, the heating element, due to its high resistance gets heated up and starts glowing and hence the term glow plug. They resemble a spark plug in size and shape.

Working
When the engine is exposed to very cold temperatures or if the engine has cooled down due to idleness, starting it would take time because the walls of the cylinder and the cylinder heads would easily absorb the heat required for combustion. This is where the glow-plug comes to play.

The working of a diesel engine and the glow plug:
The diesel engine works by following a compression-ignition cycle. Unlike spark-ignition engines, the diesel engine ignites the fuel merely with the heat generated by pressurized air. At first, the suction stroke draws the air in, and then moves up and pressurizes it. While in the case of spark ignition (SI) engines, the compression ratio is about 6-10, the CI engine this ratio is about 16-20. At this point, fuel is injected in and due to high temperature and pressure, it burns further increasing the pressure. This forces the piston down and thus, rotation happens.

The glow-plug is placed in such a way that it can heat the engine and the surrounding areas. If the temperature if the ignition chamber is less than enough for ignition, it gets detected by sensors meant for this. The glow-plugs then switch on automatically and turn red-hot, thus heating up the chamber. When ignition temperature is achieved, the glow-plug switches off.

Types of glow-plugs:
Quick start pencil elements: This type of glow plugs are used in smaller, passenger vehicles where only less heating is needed for ignition. These reach about 1625 degrees Celsius in 30 seconds.

Slow-start pencil elements
These plugs are used in heavier vehicles which require more heating. They reach a temperature of about 2000 degrees in 30 seconds.

Issues faced by a glow plug
The common enemy of a glow plug is wear and tear. It is possible to start the engine with the glow plug on. But when the engine gets ignited, the plug also receives some heat in reverse. This reduces the life of the glow plug
Due to continuous heating, there is a possibility of oxidization. Platinum and iridium are usually used in order to overcome this.

Replacing
The replacement of a glow plug usually follows no schedule. It is usually done according the suggestions given in the manual. Generally, it is good to do it for every six months or for every 60,000 miles. One of the things hat has to be taken care of, while changing the glow-plug is to ensure that the glow plug is cooled down completely.

How to replace a glow plug
First, remove the valve cover and also any cover that covers the plug. Remove the connector, and remove the glow plug using a deep socket wrench. Now screw the new glow plug all the way and put back the connector. Remember, each vehicle has its own specifications about how to replace a glow-plug. It is always best to follow them.

Selecting a reputed service provider
This is the most important factor when trying to get your car serviced. The person at the local garage may be friendly, but may not be competent enough to service your car properly and he may quote you the rates that are too high. It is advisable to go to someone who has a network of garages and guarantees you with professional service levels.

Tire pressure
Check for your car’s tire pressure as this is one of the significant factors that affect your car’s mileage and hardly cost anything. It will not take more than five minutes to get it verified.

Tire rotation
Often tire rotation is a neglected part of your car service. You should change your tires after every 8000 km. Never try to save money by avoiding this, as this can be dangerous.

Oil and transmission checks
One of the most important things in maintaining your car is changing the oil and checking the performance of your transmission. You may check for the oil and transmission by your own. But it should be also checked by the professional as well. This helps in identifying the problems that you might have skipped.

When you decide to hand over your car for servicing, make sure that you know at least the basics of servicing and what to expect from that servicing.
