Which teeth have trifurcated roots?
Maxillary teeth: trifurcated (mesiobuccal, distobuccal, palatal roots). Potential furcation defect on the mid-buccal, mesial, and distal aspects of the tooth. Maxillary first premolar: can be bifurcated (buccal and palatal roots).
What is dental furcation?
A furcation defect is a dental condition in which bone loss, which usually results from periodontal disease, affects the base of the root trunk of a tooth where two or more roots meet.
Why posterior teeth are extracted first?
Why are Maxillary Teeth Extracted before Mandibular teeth? It prevents any fall of enamel or restorative debris from falling into the extraction sockets of the lower arch.
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.
Where are furcations in teeth?
A furcation is the place where the roots of teeth fork or separate, taking different paths from one another.
How do you test for furcation?
Diagnosis of furcation involvement is based upon probing and radiographic findings. Although a straight periodontal probe may be used, detection of subgingival furcations is facilitated by the use of specially designed furcation probes (Nabers No I and No 2 probes).
How do you clean a furcation area?
The principle of sliding the brush on the tooth surface to clean the space called the furcation area applies here. As the brush gently enters the space and cannot go any further, press against the root and firmly wipe the plaque (germs and its sticky byproducts) off the root.
What is the most common tooth to be extracted?
The most commonly extracted tooth type in all age groups was the molars (60%), followed by premolars (30.8%) and anterior teeth (9.2%, Table 3).
Which teeth are the easiest to extract?
Most upper teeth are easy to get numb for an extraction. Most lower teeth are also easy except the back molars. The lower back molars are much more difficult to get numb because the bone is so thick around them that anesthetic has trouble soaking through and there are several different nerves that go to them.
