Surrounding gingival tissue may experience lymphadenopathy. The alveolar plate may exhibit crepitus when palpated. Complications
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. Causes
Dental cysts are usually caused due to root infection involving tooth decay. Untreated dental caries then allow bacteria to reach the level of the pulp, causing infection. The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots. The resulting pulpal necrosis causes proliferation of epithelial rests of Malassez which release toxins at the apex of the tooth. The bodys inflammatory response will attack the source of the toxins, leading to periapical inflammation. The many cells and proteins that rush to an area of infection create osmotic tension in the periapex which is the source of internal pressure increase at the cyst site. These lesions can grow large because they apply pressure over the bone, causing resorption. The toxins released by the breakdown of granulation tissue are one of the common causes of bone resorption. There are two schools of thought regarding cyst expansion.
Partial (minimal to moderate) improvement with monotherapy, augment with another of the first-line recommendations. Stage 2: Monotherapy with an alternative drug, then augmentation. Stage 3: Possible medication combinations—lithium plus Divalproex, lithium plus atypical, or Divalproex plus atypical. Stage 4: Combination of 2-3 mood stabilizers
Stage 5: Alternate monotherapy with oxcarbazepine, ziprasidone, or aripiprazole (all Level D). Stage 6: For nonresponse or intolerable side effects—clozapine for children or adolescents, or electroconvulsive therapy (ECT) for adolescents only. BPD II, manic or mixed, with psychosis
Stage 1: Same as BPD I without psychosis except for first-line treatment warrants a combination of mood stabilizer and an atypical antipsychotic. Stages 2–4: Varying combinations and augmentations. Stage 5: Alternate monotherapy (oxcarbazepine) plus an atypical antipsychotic. (Bipolar Disorder in Children and Adolescents, 2005). Prognosis
Chronic medication is often needed, with relapses of individuals reaching rates over 90% in those not following medication indications and almost to 40% in those complying with medication regimens in some studies. Compared to adults, a juvenile onset has in general a similar or worse course, although age of onset predicts the duration of the episodes more than the prognosis. A risk factor for a worse outcome is the existence of additional (comorbid) pathologies.Children with bipolar disorder are more likely to commit suicide than other children. Epidemiology
The prevalence of bipolar in youth is estimated at 2%. History
Descriptions of children with symptoms similar to contemporary concepts of mania date back to the 18th century.
