Las causasy consecuencias de la respiración oral
Las causas de la respiración oral pueden ir desde alergias crónicas hasta el retroceso de la mandíbula que produce la excesiva succión del pulgar, pasando por hipertrofia de las amígdalas, pólipos nasales, desviación del tabique nasal, o constricción de vías respiratorias superiores… Entre otras.
Consecuencias
Las consecuencias son variadas, y tienen un peligro más que considerable. Pasemos a verlas:
Bajo rendimiento: tener una falta de oxígeno y otros factores hormonales hacen que los niños padezcan sobrepeso, cansancio y por ende, muestren un bajo rendimiento, tanto físico como estudiantil.
Apnea del sueño: la apnea del sueño se trata de un desorden del descanso, que causa interrupciones en la respiración, además de muchas consecuencias de carácter negativo como es la alta presión arterial, problemas cardiovasculares y fatiga.
Mal aliento, enfermedad periodontal y caries dental: respirar por la boca causa que tengamos una menor humedad en la cavidad oral, o que facilita el desarrollo de bacterias y afectación por caries, enfermedad periodontal e inclusive mal aliento.
Postura alterada del cuello, la cabeza y el cuello: respirar por la boca trae consigo una posición más avanzada de la cabeza, lo que se convierte en una sobrecarga de los músculos de la espalda y el cuello.
Sistema inmune debilitado: la falta de oxigeno que se presenta en las personas que roncan debilita el sistema inmune, además de interrumpir los ciclos del sueño e interfiere en el crecimiento de la producción de hormonas.
Deformidad en la mandíbula: si el problema de respiración oral afecta al niño, puede terminar alterándose la estructura facial, lo que causaría apiñamiento dental, así como maloclusión, además de una barbilla pequeña y la alteración de la posición de la cabeza. Estos problemas necesitarán tratamiento por parte de un dentista u ortodoncista.
En caso de que tu hijo sufra de esta problemática, tendrás que acudir con él al odontopediatra de las Clínicas Propdental, a fin de valorarle y determinar cual es el tratamiento que más le conviene. Si por contra eres tú mismo quien padece esta problemática, dirígete a tu dentista de confianza de Propdental,

How Does A Dental Ultrasonic Scaler Work?
The purpose of using best ultrasonic scaler
is to facilitate the removal and elimination of agents which cause
inflammation to the teeth, plaque and its products, as well as calculus.
The term "calculus" is used to refer to a kind of dental plaque that
has hardened over time. This condition is caused by the consistent
accumulation of saliva on the plaque, and which may already be deposited
on the teeth. With the rough surface providing a favorable environment
for the increased formation of calculus, dental ultrasonic scalers make
for a viable choice of equipment fit for use in eliminating this
problem.
Scaling, when done professionally and thoroughly, ensures that the periodontium is free of harmful agents and disease. The periodontium is the mass of tissues which surround the teeth and provide support for the same. As a result of using these ultrasonic scalers effectively the teeth are maintained securely in the maxillary and mandibular bones, and which in turn helps to keep your teeth strong.
In performing its function the tip of the ultrasonic scalers vibrates following a pattern which depends on the power rating as well as the type. The water gets energy in the process of passing over the tip in order to provide cavitations and thus create an action similar to that of scouring.
Dental ultrasonic scalers work rapidly during the removal of calculus from the surfaces of the teeth. They do this via vibration actions ranging between twenty thousand and forty five thousand times per second. Most of the power, and consequently heat, for this device is focused at the tip, and which is effectively cooled using a jet of water. It is thus important to keep the scaling tip in motion over the teeth because of the heat that it generates. www.oyodental.com, as well as other professionals in the field, advises that no more than ten seconds should be spent on the same tooth. In addition to this, only a single ounce of pressure needs to be used. It is obviously important to provide and follow the stipulated guidelines and especially when it comes to people's health. For this reason, this procedure should only be carried out by professional dentists as any errors may even result in patients losing their teeth.
As a dental health professional looking for dental ultrasonic scaler, there is a wide variety of these available in the market, each with its benefits and drawbacks. They are available in different shapes, with some actually having interchangeable tips and thus providing added effectiveness at a lower price, this compared to a situation whereby you have to buy different devices for the different tips. There are also new variants which are able to carry their own supply of water. As a general rule though, finer action is experienced from devices with thinner tips.

How does a brushless electric dental micromotor work?
The article how does a brushless electric dental micro motor work?
explains how brushed motors work. In a typical DC motor, there are
permanent magnets on the outside and a spinning armature on the inside.
The permanent magnets are stationary, so they are called the stator. The
armature rotates, so it is called the rotor.
The armature contains an electromagnet. When you run electricity into this electromagnet, it creates a magnetic field in the armature that attracts and repels the magnets in the stator. So the armature spins through 180 degrees. To keep it spinning, you have to change the poles of the electromagnet. The brushes handle this change in polarity. They make contact with two spinning electrodes attached to the armature and flip the magnetic polarity of the electromagnet as it spins.
This setup works and is simple and cheap to manufacture, but it has a lot of problems:
The brushes eventually wear out.
Because the brushes are making/breaking connections, you get sparking and electrical noise.
The brushes limit the maximum speed of the motor.
Having the electromagnet in the center of the motor makes it harder to cool.
The use of brushes puts a limit on how many poles the armature can have.
With the advent of cheap computers and power transistors, it became possible to “turn the motor inside out” and eliminate the brushes. In a brushless DC motor (BLDC), you put the permanent magnets on the rotor and you move the electromagnets to the stator. Then you use a computer (connected to high-power transistors) to charge up the electromagnets as the shaft turns. This system has all sorts of advantages:
Because a computer controls the motor instead of mechanical brushes, it’s more precise. The computer can also factor the speed of the motor into the equation. This makes brushless motors more efficient.
There is no sparking and much less electrical noise.
There are no brushes to wear out.
With the electromagnets on the stator, they are very easy to cool.
You can have a lot of electromagnets on the stator for more precise control.
The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor.

Several considerations When selecting dental air compressor
Sizing your compressor
To properly size a compressor, you need to know your air consumption and the capacity of the compressor. Consumption is usually determined by how many operatories are in use at a time. Capacity is the compressor output in cubic feet per minute (cfm), and can usually be found in product literature. As a rule of thumb, each chair needs approximately 2 cfm.
Dental compressor suppliers often simplify all this and just tell how many users a compressor will support. This is helpful, but you must check the duty cycle and actual flow to ensure you’re getting what you expect. Product literature may state pump displacement but not true capacity, which is a combination of actual volume output, duty cycle, and tank size.
Capacity and reliability are related because many compressors are designed with a limited “duty cycle” — the percentage of time a compressor can run without cooling off. For example, some dental compressors have a 30% duty cycle. This does not mean it can run three hours straight in a 10-hour day, but more like 18 minutes in an hour.
The key point is that two compressors may put out the same cfm, but the one with the lower duty cycle cannot run as much without reducing its service life. Duty cycle varies widely among compressors, so ask your supplier about it.
Air quality
Compressed air quality depends on the inlet air and what the compressor adds to it. Both oil-less and lubricated compressors are used in dentistry. Both require particulate filters to remove any airborne dirt and dust. With a lubricated compressor, the system must also include reliable coalescing filters to ensure patient safety.
Most dental compressor for sale include a dryer to remove moisture. The common types are desiccant and membrane. Both types use air to purge the saturated desiccant material or membranes. This reduces the air available chairside. When selecting, consider how much dried, compressed air is needed for the purge.
Sometimes, less is more
Dental compressors have “heads,” with each one housing one or more pistons. Some models employ a single head, while others use a multihead design. A common misunderstanding is that a machine with multiple heads has built-in backup. When a multihead compressor has a malfunctioning pump, it may not be able to continue running on another head.
Assuming equal quality in two machines, the machine with more moving parts has a greater chance of failure. Single-head machines, by necessity, are generally designed for longer life. They are designed for higher efficiency and greater duty cycle to take on a constant, more demanding workload that many multihead units simply cannot handle.
Not all compressors are created equal
Manufacturers make choices in design and materials to meet target price points, so quality varies widely. Following are some points to consider when comparing compressors.
Heads should be made of quality materials and designed to remove heat. Finned cylinders, large cooling fans, and filters are important features. Components should be designed to be serviced, not replaced. For example, antifriction coatings like Teflon are widely used to reduce piston wear.
Eventually, the coating wears off and the whole piston must be replaced. An alternative method is using replaceable Teflon guide sleeves and compression rings. These may last for years, and replacing them is simple and less expensive than installing an entire new piston or head assembly.
Other signs of quality include robust tubing and fittings, as well as good vibration isolation to prevent loose wires and fittings. With respect to safety, electrical connections should be neat and touch-proof. In addition, compressors used in dental offices should be clearly marked with full UL certification. Another safety item is the storage tank, which should be ASME certified.

La influencia de los alimentos en nuestra sonrisa
Alimentos buenos para la salud oral
Las elecciones que debemos hacer si queremos tener una buena salud bucodental pasan por el consumo de lácteos como la leche, el queso, el yogurt… Esto es debido a que la presencia de calcio en estos alimentos hace que nuestra dentadura se refuerce. Las aves de corral, otras carnes y los frutos secos también nos ayudan a aportarnos el fósforo necesario para conseguir proteger el esmalte de nuestra dentadura mediante el proceso de remineralización.
Los alimentos que cuentan con un alto contenido en agua también serán buenos para nosotros, ya no sólo para estimular la saliva, sino para diluir los azúcares: las manzanas, las peras o las verduras son algunos ejemplos. Si hablamos de bebidas, siempre será el agua nuestro líquido de elección, junto con la leche.
Alimentos dañinos para la salud oral
Existe una larga, muy larga lista de alimentos dañinos para nuestra dentadura, por lo que sólo nombraremos los más representativos: chucherías, galletas, así como las patatas fritas o los pasteles son algunos de los más perjudiciales. Esto es debido a que no sólo contienen un alto porcentaje de azúcar, sino que además son pegajosas, lo que hace que se enganchen a nuestra dentadura, facilitando enormemente el entorno propicio para las bacterias. Naturalmente esto no quiere decir que se tengan que eliminar por completo de la dieta, pero sí deberemos reducir el consumo o tratar de emplear medidas preventivas para que su efecto no sea tan negativo. Por ejemplo, usar una cañita para beber los refrescos es una buena opción.
Como vemos, los alimentos pegajosos y azucarados son los peores enemigos de una dentadura sana. Si los limitamos y nos decantamos por aquellos que presenten mayores beneficios para nuestros dientes estaremos haciéndole un enorme favor a la salud de nuestra sonrisa, lo cual irá acompañado de una mejoría en nuestra estética. Si tienes más información, consúltale a tu dentista de confianza de Propdental durante la próxima visita rutinaria.
