  2. Periapical periodontitis or apical periodontitis (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root, most commonly caused by bacterial invasion of the pulp of the tooth. It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis
  3. Periapical X-rays are useful for focusing on just one or two teeth. A panoramic X-ray is used to show the entire mouth in one image. It's taken from outside of your mouth and can help identify issues like cysts, jaw disorders, or bone irregularities.

Radiographs and CBCT are valuable diagnostic tools to help you determine the presence of a root fracture. Unfortunately, unless the fracture is wider than about .15 mm (the tip of a #15 endodontic file), it cannot be visualized on the CBCT scan. However, there are some strong associations between radiographic findings and the presence of a root.

Periapical Abscess. A periapical abscess is a collection of pus at the root of a tooth, usually caused by an infection that has spread from a tooth to the surrounding tissues. (See also Overview of Tooth Disorders .) The body attacks an infection with large numbers of white blood cells. Pus is the accumulation of these white blood cells, dead. Definition: A buccal bifurcation cyst is an uncommon inflammatory cyst of the mandibular molars.. Clinical Features: It is most commonly found in individuals under the age of 20. Clinically the lingual cusps may project higher than the buccal cusps of the associated tooth. Other names it is referred to as include a paradental cyst and mandibular infected buccal cyst The detection of periapical pathosis using periapical radiography and cone beam computed tomography - part 1: pre-operative status.

Find out more about periapical periodontitis and its causes, symptoms, and treatments. What Is Apical Periodontitis? Apical periodontitis refers to the inflammation of the periodontium — the tissue that surrounds your teeth. Apical means relating to the apex, so inflammation usually occurs around the tip — or apex — of the tooth's root Periapical tissues appear normal. The removal of caries or leaking restorations will usually relieve the symptoms. Irreversible pulpitis. The pulp is more severely affected and the inflammation is irreversible. Causes: Caries. Deep restorations. Pulp exposure. Any other direct or indirect insult to the pulp This point may vary from 0.5 to 2.5 mm from the radiographic apex and be difficult to determine clinically. Calcified canals reduce the clinician's tactile sense in identifying the constriction clinically, and reduced periapical sensitivity in older patients reduces the patient's response that would indicate penetration of the foramen Inferior alveolar nerve injury - slideshare.net jame

They are slightly more common in men and have an incidence peak between 30 and 60 years. They result from infectious processes (abscess or granuloma) caused by chronic apical periodontitis, usually associated with dental cavities1-5 PA radiolucencies identification made easy! Happy learning.. Periapical radiolucencies are most commonly odontogenic. Nonodontogenic radiolucencies tend to be not localized and span across the mandible or maxilla within the alveolus and sometimes extend inter-radicularly.The most common PA pathologies can be diagnosed based on the vitality responses from the teeth The prominent premaxillae can cause malocclusion. f236 Textbook of Dental Radiology The radiographic features are quite typical of this disease and the diagnosis is made by the radiographic findings. The typical radiographic appearance is bilaterally symmetrical increase in the density of the bone Conventional periapical radiographs are the commonly employed method for evaluating root canal morphology.13 A periapical radiograph provides a two-dimensional image of a three-dimensional object and hence there is always a chance of missing any important structure present in the third dimension

appointments. Periapical radiographs usually were exposed every 6-18 months. Success of treatment for the treated teeth was based on a combination of the clinical and radiographic findings. For a tooth to be considered clinically successful, the following criteria were ap-plied: (1) no gingival swelling or residual sinus tract; (2 of periapical healing.10 It may takes many months for Figure 5: Intraoral periapical radiograph showing large periapical lesions in relation with 31, 32 and 41 Figure 6: Working length determination Figure 7: Master cone selection Figure 8: Radiograph showing obturation of 31, 32 and 41. 12 months post-operative radiograph showing healing o Intraoral periapical (PA) radiography is the primary diagnostic and most commonly used method for measuring the remaining crestal bone height while screening for implant treatment in the posterior maxillary area. 1 A significant drawback of conventional PA radiographs, however, is that 3-dimensional (3D) objects (eg, tooth or ridge) are compressed and superimposed into 2-dimensional (2D. Especially periapical radiographs taken from different horizontal angles facilitate the diagnosis. In this control, the appearance of the nasopalatine canal cyst changes, while the radicular cyst continues to be located at the apex of the central incisors [2,6]. Incisive foramen larger than 6 mm may give the appearance of cysts [8] Principles of Endodontic Diagnosis. Proper examination and testing will lead to an accurate endodontic diagnosis, allowing clinicians to deliver appropriate treatment. Proper and accurate diagnosis is paramount for successful treatment in medicine and dentistry. In endodontics, an accurate diagnosis is imperative to identify the offending tooth.

Ehnevid H, Jansson LE, Lindskog SF, Blomlφf LB Garre's sclerosing osteomyelitis is a specific type of chronic osteomyelitis that mainly affects children and young adults. This disease entity is well-described in dental literature and is commonly associated with an odontogenic infection resulting from dental caries. This paper describes a case of Figure 2: A 50-year-old woman with osseous (cemento-osseous) dysplasia (OD/COD) and osteomyelitis. Panoramic (a) and periapical (b) radiographs show a mostly radiopaque OD/COD lesion accompanied by lamellar periosteal formation of new bone along the buccal surface of the mandible.The lesion can be seen opposite the mandibular left first molar in a standard occlusal radiograph of the mandible. Dens invaginatus (DI), also known as tooth within a tooth, is a rare dental malformation found in teeth where there is an infolding of enamel into dentine. The prevalence of condition is 0.3 - 10%, affecting more males than females. The condition is presented in two forms, coronal and radicular, with the coronal form being more common. DI is a malformation of teeth most likely resulting from.

Radiographic features of disease of Maxillary Sinus. The Maxillary Sinus is largest of all the Sinuses and is located in the maxilla. The air filled cavity is lined by pseudo stratified columnar epithelium. The Maxillary sinus is pyramidal in shape, Boundaries of Maxillary sinus are the Medial wall is formed by the lateral wall of nasal cavity. The radiograph should show clearly the apical and periapical structures of teeth and associated tissues. The relationship of the maxillary molars and premolars to the floor of the maxillary sinus can be examined, and radiographs may reveal recurrent caries or periapical radiolucencies associated with an established infection ( Figure 3 ) Stafne's defect is usually discovered by chance during routine dental radiography. Radiographically, it is a well-circumscribed, monolocular, round, radiolucent defect, 1-3 cm in size, usually between the inferior alveolar nerve and the inferior border of the posterior mandible between the molars and the angle of the jaw Nonetheless, awareness of the potential benefits of digital imaging generally and digital radiography specifically is increasing with each new technical innovation being introduced. It has been estimated that, by 2016, the proportion of digital dental imaging systems will double from the number estimated in 2009. [ 8] Next: Digital Technology OPG X-rays.
