[5]: 141 Low grade chronic periodontitis commonly occurs on either the wisdom tooth or the second molar, causing less obvious symptoms such as bad breath and bleeding from the gums. The teeth can also remain asymptomatic (pain free), even with disease. [7] The term asymptomatic means that the person has no symptoms.
Tooth eruption is a process in tooth development in which the teeth enter the mouth and become visible. It is currently believed that the periodontal ligament plays an important role in tooth eruption. The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months ...
A Mesio-impacted, partially erupted mandibular third molar, B Dental caries and periodontal defects associated with both the third and second molars, caused by food packing and poor access to oral hygiene methods, C Inflamed operculum covering partially erupted lower third molar, with accumulation of food debris and bacteria underneath, D The upper third molar has over-erupted due lack of ...
5.i Impeded eruption of teeth (apart from 3rd molars) due to crowding, displacement, the presence of supernumerary teeth, retained deciduous teeth, and any pathological cause 5.m Reverse overjet >3.5mm with reported masticatory and speech difficulties 5.p Defects of cleft lip and palate 5.s Submerged deciduous teeth
An impacted tooth is one that fails to erupt into the dental arch within the expected developmental window. Because impacted teeth do not erupt, they are retained throughout the individual's lifetime unless extracted or exposed surgically. Teeth may become impacted because of adjacent teeth, dense overlying bone, excessive soft tissue or a ...
Type II involves a greater eruption pattern, not complete, among the teeth distal to the most mesial affected tooth. It is difficult to diagnose between these two types of failure of eruption because 2nd molar does not erupt until a patient is 15 years of age. Plenty of times, patient's receive orthodontic care much before they turn 15 years old.
Enamel hypoplasia. Enamel hypoplasia is a defect of the teeth in which the enamel is deficient in quantity, [1] caused by defective enamel matrix formation during enamel development, as a result of inherited and acquired systemic condition (s). It can be identified as missing tooth structure and may manifest as pits or grooves in the crown of ...
The permanent mandibular molars are not considered to have any teeth that precede them. Despite being named molars, the deciduous molars are followed by permanent premolars. In the universal system of notation, the deciduous mandibular second molars are designated by a letter written in uppercase. The right deciduous mandibular second molar is ...
