Periapical dental radiograph showing chronic periapical periodontitis on the root of the left maxillary second premolar. Note large restoration present in the tooth, which will have undergone pulpal necrosis at some point before the development of this lesion. Specialty: Endodontics [1] Complications
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain. One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament ...
In 1890, W.D. Miller, considered the father of oral microbiology, was the first to associate pulpal disease with the presence of bacteria. [11] This was confirmed by Kakehashi, who, in 1965, proved that bacteria were the cause of pulpal and periradicular disease in studies using animal models; pulpal exposures were initiated in both normal and germ-free rats, and while no pathologic changes ...

The blue arrow, in the middle, shows up to 80% bone loss on tooth No. 21, and clinically, this tooth exhibited gross mobility. Finally, the peach oval , to the left, highlights the aggressive nature with which periodontal disease generally affects mandibular incisors.
Overlying the bone is the gingival soft tissue, which is, on average, about 1 millimeter in thickness. [2] Because of this gingiva, the crown, which exists entirely outside of the surrounding bone, is somewhat obscured at the apical millimeter or so. Thus, crown and root can be used as anatomical terms, defining the actual parts of a tooth.
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
