What is a mandibular molar?
Anatomical terminology. The mandibular first molar or six-year molar is the tooth located distally (away from the midline of the face) from both the mandibular second premolars of the mouth but mesial (toward the midline of the face) from both mandibular second molars.
What causes molar Hypomin?
It is thought to be caused by a disturbance in tooth development around the time of birth or in the first few years of life. The cause of it is not fully understood although severe childhood illnesses, high fevers, or a traumatic birth period have all been suggested as possible causes.
What teeth are trifurcated?
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). Potential furcation defect on the mesial and distal aspects of the tooth.
Which teeth have 2 roots?
The premolars and back molar teeth (chewing teeth) have 2 or 3 roots, each containing either 1 or 2 root canals. The more roots a tooth has, the longer the treatment will take to complete.
Do molars hurt coming in?
Pain During Their Eruption The first front tooth is often the most sensitive, but molars coming in can also be painful for your child. Unlike an incisor, which can cut the gum more efficiently, a molar’s larger and duller surface area makes the process more uncomfortable for some children.
Is molar incisor Hypomineralization genetic?
Background: The etiology of molar-incisor hypomineralization (MIH) remains unknown. Studies indicate that it is multifactorial, and that genetic and environmental factors are involved.
Why do I have Mamelons on my teeth?
Why Do Teeth Have Mamelons? When an adult tooth forms underneath the gum tissue, there are three groups of cells that form the incisal edge of the tooth. This helps the tooth break through the gum tissue more easily. However, when the teeth erupt, some parents are concerned that the tooth appears to be damaged.
Can a molar have 4 roots?
The majority of human maxillary first molars is usually described as having three roots, but different morphologies were documented in several studies and case reports. One very rare and less investigated anatomical anomaly is the occurrence of four radicular structures in the upper first molars.
