Microgenia can be presented when there is inadequate bone depth at the apex of lower anteriors or the base of mandible and vice versa. Position
TransverseA transverse jaw position is known as Laterognathia. This term describes a lateral bite in the lower jaw  and is often associated with a unilateral crossbite at an early age  This can lead to bone development of an asymmetrical mandibular ramus resulting in asymmetry in the whole of the lower face. Treatment of laterognathism is either possible with orthodontic tooth movement or a surgical relocation of the lower jaw. VerticalOne of the ways in which a jaw can develop abnormally is in the vertical dimension. Abnormal growth can occur in the maxilla and the mandible. The jaw is usually loosely used to refer to the mandible (considered the lower jaw). However, the maxilla is also a jaw and should thus be referred to in this respect as well. The vertical jaw abnormalities relating to the mandible are in relation to excessive vertical growth and excessive horizontal growth, measured by the maxillary-mandibular plane angle (MMPA). The vertical jaw abnormalities relating to the maxilla are in relation to excessive downward displacement (EDD) and insufficient downward displacement (IDD). These terms used to previously be known as vertical maxillary excess and deficiency. This nomenclature changed because excess and deficiency typically refer to size. Whereas when assessing this clinically, one would measure the distance between the central incisors and the upper lip, which, in fact, denotes position rather than size.
Periodontal abscess—a localized, purulent infection involving a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket. Pericoronal abscess—a localized, purulent infection within the gum tissue surrounding the crown of a partially or fully erupted tooth. Usually associated with an acute episode of pericoronitis around a partially erupted and impacted mandibular third molar (lower wisdom tooth). combined periodontal/endodontic abscess

Treatment
An important factor is whether the involved tooth is to be extracted or retained. Although the pulp is usually still vital, a history of recurrent periodontal abscesses and significantly compromised periodontal support indicate that the prognosis for the tooth is poor and it should be removed. The initial management of a periodontal abscess involves pain relief and control of the infection. The pus needs to be drained, which helps both of these aims. If the tooth is to be removed, drainage will occur via the socket. Otherwise, if pus is already discharging from the periodontal pocket, this can be encouraged by gentle irrigation and scaling of the pocket whilst massaging the soft tissues. If this does not work, incision and drainage is required, as described in Dental abscess#Treatment. Antibiotics are of secondary importance to drainage, which if satisfactory renders antibiotics unnecessary. Antibiotics are generally reserved for severe infections, in which there is facial swelling, systemic upset and elevated temperature.
