The permanent maxillary central incisor is the widest tooth mesiodistally in comparison to any other anterior tooth. It is larger than the neighboring lateral incisor and is usually not as convex on its labial surface. As a result, the central incisor appears to be more rectangular or square in shape.
Symptoms of holoprosencephaly range from mild (no facial/organ defects, anosmia, or only a single central incisor) to severe . The symptoms are dependent upon the classification type. [3] There are four classifications of holoprosencephaly, as well as a mild "microform" variant. Gross pathology specimen from a case of alobar holoprosencephaly
Having ruled out serious injuries, a full trauma, dental and medical history is undertaken. This will include understanding if the patient is currently having symptoms, has a history of dental trauma, and their tetanus status. [8] Following a complete history, a clinical examination is then undertaken. Extra-oral examination includes:
There are several signs and symptoms associated with the eruption of primary teeth. It is a process that begins with the eruption of the mandibular central incisors at the age of 6 months. A common symptom among young children is a mild rise of temperature, however this is not necessarily classified as a fever.
Level 1 radiographic examination for suspected macrodontia, however, should only be done after considering the patient's medical records (positive medical history of congenital syndromic conditions related to genetic disorders), the clinical signs and symptoms (the enlarged tooth shape/size), as well as the risk/benefits of exposure to harmful ...
Dilaceration is a developmental disturbance in shape of teeth. It refers to an angulation, or a sharp bend or curve, in the root or crown of a formed tooth.This disturbance is more likely to affect the maxillary incisors and occurs in permanent dentition. [1]
Microdontia is a condition in which one or more teeth appear smaller than normal. In the generalized form, all teeth are involved. In the localized form, only a few teeth are involved. The most common teeth affected are the upper lateral incisors and third molars.
Arguably the main observation to carry out in a patient to assess maxillary excess or deficiency is the upper incisor/gum show when at rest and smiling. In other words, the relationship between the upper lip and upper central incisors when at rest and smiling. [41] Ensure the patient's head posture is correct and the lips are at rest to ...
