Radiolucent lesions seen on radiographs develop from both odontogenic and non-odontogenic structures. They characterize a broad spectrum of lesions (Avril et al., 2013) A sequential study of all the radiographic characteristics of the image helps ensure recognition and collection of all the information contained in the image and in turn improves the accuracy of interpretation. Analysis of any image should include: Step 1: Localize the anomaly Step 2: Assess the periphery and shape Step 3: Analyse the internal structure Step 4: Analyse the effects of the lesion on peripheral structures. A radiolucent lesion in the mandibular premolar region can have the following differential diagnosis; 1. Mental foramen: It is typically the anterior limit of the Inferior Alveolar Nerve.

Acute/Chronic apical periodontitis. 3. Periapical abscess: Small or large radiolucent area, ill-defined or diffused, may have cortical expansion in chronic situations. Associated tooth will have extensive caries or restoration involving or in close proximity to pulp space. Will have associated widening of the Periodontal Ligament Space. Pulp vitality tests are needed to confirm diagnosis. 4. Periapical granuloma: Well circumscribed, rounded (around apex). May have a thin radio-opaque border, tooth involved will most likely have deep carious lesion or restoration in close proximity to pulp space. Tooth will be non-vital. 5. Periapical cyst: Similar to a granuloma, the differentiation may not be possible unless other distinctiveness of a cyst, such as displacement of contiguous structures and expansion of the external cortical boundaries of the jaw, are seen. Lesions larger than 1 cm in diameter usually are radicular cysts. Other periapical radiolucencies to consider are an early stage of Periapical cemental dysplasia and an apical scar or a surgical defect because in such cases, normal bone may never fill in the defect completely. The patient’s history helps with the
Overall the patient had excellent homecare and was a Calculus Level One. There weren’t any risk factors discussed with this patient, but her concern about the throbbing in her upper jaw was addressed. Her general goal of the appointment was to keep her plaque score the same or lower since she was at 14%. She was a Periodontal Case Type Two based on the bleeding from probing, bone loss, and previous radiographs. The patient said she has been flossing more and is really trying to maintain her plaque score.
Mouth. Oropharynx absent of lesions and/ or exudates. Mucus membranes, gingivae pink and moist. Upper and lower teeth are present. Multiple fillings in good repair. Tongue pink and smooth. Protrudes midline. No abnormal movements/ tremor noted.
Osteosarcoma(OS) is a primary malignant tumor of bone which is characterized by the formation of osteoid tissue. Although it is the most common malignancy of long bones after multiple myeloma [2], it is a relatively rarer entity in the craniofacial region. About 6% of Oss arise in the jaws .The estimated incidence of the new cases of Jaw OS (JOS) per year is 0 .07 in 100,000. (1) The etiology of OS is unknown, but some risk factors such as a previous history of ionizing radiation, alkylating agent, retinoblastoma and benign bone lesions such as paget disease and fibro osseous dysplasia have been associated with the development of head and neck OS.(2-4) JOS occur with a peak in the third through fifth decades of life. The mean age is
An orofacial examination was performed to assess the structural and functional integrity of the oral mechanism. The exam did not reveal anything of clinical significance.
The images pictured above are bite-wing radiographic images. A bite-wing image includes the crown of maxillary and mandibular teeth, interproximal areas, and areas of the crestal bone, which is the coronal portion of the alveolar bone also known as the alveolar crest, on the same image. Bite-wing images usually are used to detect interproximal caries and for the detection of early carious lesions that are not clinically evident. Bite-wing radiographic images are also used to monitor the progression of dental caries, assessing existing restorations, and examining the alveolar crest levels between the teeth. The receptors appear to be placed correctly as they are parallel with the crown of the tooth, also both the first and second molars are
PA X-rays provide a visual of assessment of tooth and supporting bone structure, detect abnormalities in an area of teeth from the crown to where the root is anchored to the jaw. This is performed to find abnormalities in root structure and surrounding bone.
First studies looked for abnormalities within craniofacial structures using techniques and processing common in medical imaging such as cephalometry or computed tomography (CT). In [6] authors applied sophisticated volumetric analysis on magnetic resonance imaging (MRI) of the
Dentistry is a field of exactness and the upmost precision. Today, most dentist continue to use the limited 2D plaster models that only show the teeth and gums from a lateral position showing only the outside and the inside of the mouth. Plaster models tend to only show the visible, apparent problems that may be wrong with a patient but cannot effectively showcase the many other possibilities that may be causing a patient to have malocclusions and misalignments of the jaw. Cone beam computed tomography shows the roots of the teeth with precision while also displaying the bones in the head so that any anomaly can easily be noticed and allow for easier work. There have also been specific studies to determine how each person varies in their nasal passages and how this can cause certain problems in each case. Overall, Cone Beam Computed Tomography proves to be the best option for orthodontists to use because it accurately scans the facial structure and teeth allowing for the ultimate amount of precision by orthodontists when dealing with the amount of space teeth need to be moved and compare that with the forces particularly required to achieve a satisfactory product. With this being said, Cone Beam Computed Tomography should be pushed widespread into the field of Orthodontics so that in cases of great complexity patients with the proper health can be properly helped with their situations. This technology can successfully bring the accuracy into the field needed to deal
Odontogenic Keratocyst: it is an odontogenic developmental cyst lesion with unique microscopic appearance. It is usually multilocular and lateral periodontal cyst is not. This lesion is most often seen in the mandibular third molar, but lateral periodontal cyst is frequently located on the mandible in relation to the premolars and lateral incisors.
A year later in 1988 Gardner et al. [2] reported eight other cases and called the lesions glandular odontogenic cysts (GOCs) because there was a mucin structure in the cyst epithelium that
Dentigerous cyst is a common developmental odontogenic cyst, mostly seen in relation with impacted mandibular third molars and maxillary canines. Usually, they are asymptomatic and this delays the diagnosis. A combination of clinical, radiographic, and histopathological examination is necessary for arriving at the final diagnosis. Prompt diagnosis and treatment is mandatory to prevent dreadful

Salivary gland tumors are a morphologically diverse group of neoplasms, which may present considerable diagnostic and management challenges for the pathologist and surgeon. Salivary gland tumors are rare with an overall incidence in the western world of about 2.5 to 3.0 per 100,000 per year. About 80% of all lesions are benign; hence salivary malignancies are particularly rare, comprising less than 0.5% of all malignancies and about 5% of cancers in the head and neck. (1)
