Which film image is most useful in diagnosing periodontal disease?
Technical problems with radiographs The long cone paralleling technique is recommended for all periapical radiographs taken for periodontal diagnostic reasons, as it produces the most realistic image of the alveolar bone.
What are the radiographic signs of early periodontal disease?
In the event of clinical signs of periodontitis, probing pocket depths and/or recession, being encountered in a clinical examination, radiographic examination yields some information on: evident bone levels; evident patterns of bone loss, even or angular; tooth-root lengths, morphologies and topographies; and …
How are radiographs valuable in evaluating periodontal disease?
Radiographs are commonly used in the diagnosis of periodontal diseases. They can be used to assess bone loss and the pattern of loss as well as in the identification of other periodontally relevant features, such as overhanging restoration margins, calculus deposits and furcation lesions.
How do you treat periodontal disease in horses?
If a horse develops periodontal disease, a veterinary dentist will examine the teeth in case extraction or realignment is necessary. The extent of bone loss, if any, should be evaluated. If the horse has acute symptoms such as inflammation and bleeding, a course of antibiotics will be prescribed to combat infection.
How is the radiographic evidence of bone loss determined?
Radiographs are an indirect method for determining the amount of bone loss in periodontal disease; they image the amount of remaining bone rather than the amount lost. The amount of bone lost is estimated to be the difference between the physiologic bone level and the height of the remaining bone.
What radiographic technique is best when assessing the periodontal bone?
Periapical or bitewing radiographs are the most common types of radiographs used for evaluation of periodontal bone loss.
What causes periodontal disease in horses?
Periodontal disease is the leading cause of tooth loss in horses, especially in older horses, and it is primarily caused by food debris impacted between cheek teeth. For the most part, information about how to diagnose, treat and help horses heal with periodontal disease is available to equine practitioners.
What is periodontal disease in horses?
Periodontal disease refers to inflammation of the structures that support the tooth (including the gum, periodontal ligaments and the bone within which the tooth sits). Studies have shown that a third of all horses show evidence of periodontal disease – in older horses this percentage is much higher!
What radiographic features might you see in molar incisor pattern periodontitis?
Radiographic examination typically shows significant bilateral, symmetric bone loss in the permanent first molar and incisor regions. The bone loss often exhibits a vertical pattern in the first molar region and a horizontal pattern in the incisor region.
Which radiographs tend to be most accurate in the determination of bone loss?
Can horses get gum disease?
What is Eorth horse?
EORTH is a newly recognized pathology affecting both the incisors and canine teeth of the horses typically greater than 15 years of age. EORTH is characterized by internal and external resorption of dental structure sometimes associated with excessive production of cementum on the exterior of the tooth.
How do you test a horse for periodontal disease?
Once the horse is sedated and the head (including the eyes, sinuses, nostrils, lips and front teeth) have been examined a speculum (Gag) is applied. In order to identify periodontal disease the mouth must be thoroughly rinsed and a bright light, a mirror and probes used to examine around teeth.
This is the first step in periodontal disease, it is called gingivitis. As the gum becomes inflamed it will swell and bleed, which allows the bacteria to enter the horse’s blood stream and travel around the body, so periodontal disease can affect all areas of the body not just the horse teeth.
Is there a cure for equine odontoclastic tooth resorption and hypercementosis?
Equine odontoclastic tooth resorption and hypercementosis There is a particular form of periodontal disease about which little is known and for which there is currently no cure, this disease Equine odontoclastic tooth resorption and hypercementosis or EOTRH occurs in Australia and requires careful management.
What is a periodontal ligament in a horse’s mouth?
The periodontal ligament plays a very important role in the horse’s mouth, it is responsible for stabilising the tooth against the forces it experiences during chewing but also has the ability to detach and reattach, allowing the continuous eruption that occurs in horses teeth.
