Serving as the “anchor”, it is buried deep into the sockets of the jawbone in order to keep the tooth securely in place. Even though it is not visible to the naked eye, the root actually makes
The author concluded that with regular periodontal maintenance, removal of root surface accretion for better periodontal tissue attachment was more important than any surgical procedures.
Molars erupt at different times in life. The first set of molars usually erupts around 6–7 years of age. The second set of molars typically erupts around 11–13 years of age. The third set of molars usually erupts between the ages of 17–21. This set of molars is often referred to as wisdom teeth. Wisdom teeth often become impacted, but any molar or set of molars can become impacted.
WookHeo, Dong-SeokNahm, and Seung-HakBaek (2007)32performed study to compare the amount of anchorage loss of the maxillary posterior teeth and amountof retraction of the maxillary anterior teeth between en masse retraction and two-step retraction of the anterior teeth.30 female adult patients with Class I malocclusion and lip protrusion were included in the study. The sample was subdivided into group 1 (en masse retraction) and group 2 (two-step retraction). Lateral cephalograms were taken before (T1) and after treatment (T2). Nine skeletal and 10 anchorage variables were measured, and independent t-test was used for statistical analysis.The amount of horizontal retraction of the maxillary anterior teeth was not different between the two groups, there was mild labial movement of the root apices of the upper incisors in group 2 at T2. No significant difference in the degree of anchorage loss of the maxillary posterior teeth was observed between the two groups. Bodily and mesial movements of the upper molars occurred in both groups. A 4 mm of the retraction of the upper incisal edges resulted from 1 mm of anchorage loss in the upper molars in both groups.
The morphology of the root canal systems of mandibular molars may vary according to ethnic differences and origin, age, gender, and study design(2). The roots and morphology of mandibular molars present clinical complications that affect the success of endodontic therapy. Therefore, clinicians must be able to identify the root canal structure before or during a root canal treatment(3).
The growth of wisdom teeth is the last teeth development stage that children experience. It, however, comes with certain discomforts. Wisdom teeth are normally the lower and upper molars that children develop in stages. The first molars appear when the kids are about 6 years old, the second at the age of 12, while the third molars develop between 17-21 years old.
An impacted wisdom tooth is one that fails to completely rise through the gums -- the term is erupt. Wisdom teeth that only partially erupt can leave space for bacteria to enter around the tooth. Infection is a risk in these cases.
The extraction of third molars, also referred to as wisdom teeth is one of the most debated topics among dental professionals and accounts for a large portion of dental revenue. Just about everyone develops third molars and if they erupt into the oral cavity, they function as the most distal grinding teeth in the oral cavity. However it is very common for these teeth to develop in an irregular pattern also referred to as impaction. If this happens it is highly recommended that the patient have them removed before they cause pain or damage to the surrounding teeth. Other common reasons for extraction include symptoms of pathological findings as well as prevention of future problems further down the road. Due to the fact that there are many different issues that could potentially develop due to third molars it is
The absence of wisdom teeth, also known as third molar agenesis, is likely influenced by both genetic and environmental determinants. It is known that third molar crypts begin forming around age 3, calcification starts around age 7 and ends by age 16, and eruption can occur starting at 17 years of age.1 Manifestation of third molar agenesis is variable. Individuals may have uni or bilateral agenesis of one, two, three, or all four third molars.2 Agenesis in the upper jaw is 36% more common than lower jaw.2 Complications arise when the teeth are impacted which can cause infection, crowding of existing teeth, cavities both above and below the gum line, and other negative side effects.3 Removal of impacted third molars is a clinical method that is used to eliminate the associated risks.3 The degree to which genetic factors influence
Once the child has at least four permanent teeth in the mouth, the third and final treatment begins with a device used to accommodate the incoming adult teeth. This is a vital stage in our treatment process because as the adult teeth are forming, the gum tissue fibers are beginning to anchor these teeth in the mouth. When using this third phase of treatment, the Perfect Start System ensures the adult teeth erupt into their proper position and the natural fiber bundles are able to form, therefore locking them into the correct alignment. This method works to prevent any new erupting
Wisdom teeth are a third set of molars; they are large, extraneous, impacted teeth that sometimes have to come out. Around the tenth birthday the last set of molars begin forming. These teeth are the last set of teeth to come in and do not erupt until the ages of 17 and 25. Although, some individuals have them appear many years later. The nickname “wisdom teeth,” comes from the belief that people are wiser around these ages.
Your dentist may place a temporary crown over your tooth that will last for a few weeks while your permanent crown is custom made for you. Before the crown is put on, all the decayed enamel has to be removed. If your cavity is large, there may not be enough of it left to hold onto the crown. When that's the case, your dentist can insert a post into the root of your tooth. The crown then attaches to the post so it is held secure enough for you to eat normally. A crown is a cap made from porcelain, metal, or a combination of the two. If you choose a porcelain crown, it will blend in with your other teeth and not be noticeable. Porcelain is a good choice if you have a root canal in your front tooth. Metal might be a better choice for a molar since it is more durable and less likely to chip from the pressure of
The teeth are the hardest substances in the human body. They are built for biting, grinding and chewing, teeth are composed with most prominent inorganic minerals like calcium and phosphorus. Every tooth is embedded in a socket called gum and are made up of four different types of tissue: enamel, cementum, pulp and dentin. The enamel which is the hardest, white outer part of the tooth covers the crown which is placed above the gum. The cementum, coats the roots of the teeth firmly to the gums and jawbone. At the very centre between dentin and cementum, called pulp, where connective tissue, blood vessels and nerves are located. Dentin makes up most the tooth, guarding teeth from the wear and tear of chewing, protects against temperature changes and
Teething pain sometimes referred to as “ dentitio difficilis” is the commonest symptom associated with the eruption of primary dentition. Adults assume an infant is experiencing pain because they appear distressed, or because they believe the incisal edges of teeh cut through the alveolar bone and gingival during eruption. Pain may result from elevation of inflammatory mediators in the crevicular fluid and in tissue surrounding the erupting teeth, which stimulate nociceptive receptors.Local pain may be further exacerbated by rubbing or scratching the gingival tissues, by biting in to hard objects or by presence of pathology
