Now let us see what you mean by the term prognathism & something more about that. The word prognathism is derived from the Greek word pro, which means forward, & another word gnathos, which means jaw. This is a term which used to describe the positions of the mandible & maxilla & their relations to the skeletal base where either of the jaws is protruding out. In dentistry, this is assessed either clinically or radio-graphically in oral & maxillofacial surgery, & orthodontics.

Cephalometric analysis is the most accurate way of determining all the various types of prognathism as it includes the assessments of the skeletal base, the facial height, assessment of the soft tissue & the anterior dental angulations. In Maxillary prognathism it is the maxilla that protrudes, affecting the middle part of the face & is also a common feature seen in many people world over. Whereas in Mandibular prognathism, it is the mandible that protrudes which this affects the lower part of the face.

In Alveolar prognathism, the portion of the maxilla where the teeth are located is the part which protrudes, in the dental lining of the upper jaw. Prognathism can also be used to describe ways that the maxillary and mandibular dental arches can relate to one another. When there is either maxillary or alveolar prognathism or both, which causes an alignment of the maxillary incisors considerably front of the lower teeth, the condition is called an overbite, & when the reverse is the case, the condition is referred to as an under-bite.

Pain is the most common sign of any medical problem & to prevent that most of the time anesthesia may be regarded as a basis in the development of modern medical science. Dental pain or a toothache is one of the worst things anyone can experience.

There have been a lot of development of modern equipment & technical skills, & if there is just any one thing that most of the dentists have not been able to control, is the pain that presents itself in a many ways. In fact the nerve in the tooth, which is also called a pulp, has fibers that can transmit only the pain as a response to any kind of stimulus. Some people get very much scared visit a dentist, while some others do not. So here is where the anesthesia helps.

The use of local anesthesia for dental care is very much high world over, but it has certain risks which you may want to avoid. For most of the patients, local anesthesia is the choice to avoid even the sensation of the dental drill. The following choices may be considered & you can seek out the help of dentists who offer certain other alternatives to the usual nerve block with local anesthetics, for many reasons.

The standard inferior alveolar nerve block carries the risk of a permanent damage of the nerve to the inferior alveolar nerve, which could be prevented by some of the above following options. So this is all about dental anesthesia.

The modern dentist has an increasingly sophisticated arsenal available to aid patients in fighting tooth decay. One member of this arsenal, the dental sealant, has been available for 25 years continually undergoing refinements.

Due to the nature of the molars, intrinsically having numerous fissures and microscopic cups, they are far more difficult to clean and more susceptible to decay. And although increased widepsread public health measures to help combat decay such as fluoridation and vastly improved dental hygeine methods, molar decay remains a consistent threat to healthy teeth. Dental sealants were developed in the 1960s and 1970s to help combat this susceptibility.

Dental sealants are used to cover and close the small fissures and cups that harbour plaque and eventually decay. The application is usually performed by a dentist and involves painting a uniform layer of resinous plastic sealant on to the teeth. The compound used is very similar to that used to create “white” plastic fillings.

The plastic compound is then set by focusing blue spectrum natural light on it. Once cured, the plastic sealants form a thin, smooth, highly durable layer over the treated regions. Since the molar’s surface has been smoothed out, regular brushing becomes far more effective at removing plaque.

In spite of near continual use, and the many high stresses and strains applied to teeth through biting and chewing, the cured seal can last for upward of 5 years but should be inspected regularly for damage. In the event of damage to the sealant, a new layer of sealant can be applied over the corrupt areas.

Despite dental sealants being close to 100% effective in preventing decay in molars and it being an only moderately expensive treatment, it is estimated that fewer than 25% of the population have dental sealants.

Impacted teeth occur either because the path for their emergence is blocked, or because they have formed in the wrong position in the mouth. The eruption of teeth into mouth is not fully understood, but it is probably the result of rapid multiplication of the cells which from the tooth root, the pressure of which thrust the tooth through the overlying bone.

In cases of impaction, the problem is not usually one of failure within the developing tooth itself, but either of its position or of its relation to the other teeth nearby. Where there is crowding, that is, inadequate space in the mouth for all the teeth, the last teeth to erupt often have insufficient room, because the space available has all been taken by the teeth which have already emerged. Under these circumstances, the later erupting teeth may grow through, but out of line, or alternatively, they may be unable to emerge fully. When a tooth fails to erupt, either fully or partially, it is described as being impacted.

The cause of the crowding which leads to most impactions is not really understood, but it may arise as the result of the individual inheriting large teeth from one parent and small jaws from the other. It has also been suggested that there may be an evolutionary process in progress leading to a reduction in the size of the human jaw.

Sometimes, teeth are impacted as the result of their being formed in the in the wrong position. For example, upper canine teeth are sometimes too deeply placed, so that when they begin to erupt, they grow towards the alveolar bone [bordering the gum]. It is then not usually possible for them to erupt.

Impactions are comparatively uncommon in the milk teeth [called the deciduous dentition] because, as they are small, crowding is usually less. It is possible for any permanent tooth to become impacted, but impaction due to overcrowding most often affects wisdom teeth, the third molar, canines and premolars [situated in front of molar]. Impactions which are due to tooth development in incorrect positions affect upper canines more commonly than other teeth, and the problem often runs in families, showing that it inherited.

Taking care of our teeth is hygienic. Mouth is home to thousands of bacteria and if its not cleaned properly, you are prone to oral bacteria related diseases. Many people think brushing is enough, unfortunately experts believe you should visit a dentist at least twice a year to get the teeth professionally cleaned and check for repair works.
