What is a Dilacerated tooth?
By definition, dilaceration is an abnormal angulation or bend in the root and less frequently, the crown of a tooth. Most cases are idiopathic and have no clinical feature [1]. In limited cases with recognized cause, injury was the first reason.
What causes Dilacerated?
The possible causes for dilaceration of a permanent tooth are traumatic dental injury to the primary predecessor, idiopathic developmental disturbance, a retained or ankylosed primary tooth, and the presence of supernumerary tooth or teeth.
What causes a curved root?
Curved roots (Dilaceration) This portion of the tooth is called the root, and this is the part of the tooth which is embedded into the jawbone. Sometimes these roots can develop sharps bends. It is thought that this occurs due to a trauma sustained during the tooth’s development.
What is supernumerary root?
Supernumerary roots are one of the development anomalies pertaining to the tooth root morphology. It is generally well known that the deciduous and permanent anterior teeth have a single root. Maxillary molars have three roots and mandibular molars have two roots.
How common is Microdontia?
Microdontia is a type of dental anomaly in which teeth are smaller in size than normal. This abnormality can occur in permanent teeth and primary teeth. According to epidemiological studies, the prevalence of microdontia ranges from 1.5 to 2% and occurs more frequently in females than males.
What causes long roots in teeth?
In Turner syndrome, which is caused by monosomy or the partial absence of the X chromosome, characteristic extra multiroots are seen in the mandibular premolars. In monogenic disorders, oculo-facio-cardio -dental (OFCD) syndrome is associated with extremely long roots.
Are curved tooth roots normal?
Prevention/ Treatment The slight curves shown on these molar teeth are normal curves. Extreme curvature of roots are known to be dilaceration.
How do you pull a curved root tooth?
Extracting an impacted tooth or a tooth with curved roots typically requires cutting through gum tissue to expose the tooth. It may also require removing portions of bone to free the tooth. Some teeth must be cut and removed in sections.
How is a curved root canal treated?
Use of flexible files
- Anti-curvature filing.
- Modifying cutting edges of the instrument by dulling the flute on outer surface of apical third and inner portion of middle third, which can be done by diamond file.
- Changing canal preparation techniques, i.e. use of crown-down technique.
Which of the following teeth most often exhibit supernumerary roots?
Supernumerary roots is a condition found in teeth when there may be a larger number of roots than expected. The most common teeth affected are mandibular (lower) canines, premolars, and molars, especially third molars.
Why did my tooth have 3 roots?
A rare dental trait that is more common in Asian and Native American populations – three-rooted molars – could have its origins in trysts with our archaic relatives, the Denisovans, according to new research.
How do I fix microdontia?
If veneers are not the best fit for you, dental crowns and dental bonding are two alternative solutions used in correcting microdontia. While crowns are known for covering teeth, they are great for disguising and protecting the small teeth in question.
What causes dilaceration at the root of a tooth?
Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth, but the criteria in the literature for recognizing root dilaceration vary.
Where to look for dilaceration of the maxilla?
Dilaceration can be seen in both the permanent and deciduous dentitions, and it is more commonly found in posterior teeth and in the maxilla. Periapical radiographs are the most appropriate way to diagnose the presence of root dilacerations.
What should I do if I have a dilacerated tooth?
Dilacerated tooth when presented as a problem, is usually difficult to treat especially when it involves the root. Root canal treatment on dilacerated tooth is very challenging and normally requires an endodontist to complete.
Can a missing tooth be a sign of dilaceration?
Most cases of radicular dilaceration are not recognized clinically. If the dilaceration is so pronounced that the tooth does not erupt, the only clinical indication of the defect is a missing tooth. If the defect is in the crown of an erupted tooth, it may be readily recognized as an angular distortion (Fig. 31-20 ).
