Hyperdontia is the condition of having supernumerary teeth, or teeth that appear in addition to the regular number of teeth (32 in the average adult). They can appear in any area of the dental arch and can affect any dental organ .
Ovarian teratomas represent about a quarter of ovarian tumors and are typically noticed during middle age. [10] Testicular teratomas represent almost half of testicular cancers. [13] They can occur in both children and adults. [14] The term comes from the Greek word for "monster" [15] plus the "-oma" suffix used for tumors.
Autoimmune oophoritis can present with a wide variety of symptoms. It begins with the main symptom, which is amenorrhea , where there is an irregular or no menstrual period at all. Other symptoms are related to ovarian cysts , and more common ones are also listed below.
The ovarian fibroma, also fibroma, is a benign sex cord-stromal tumour. Ovarian fibromas represent 4% of all ovarian neoplasms. [ 1 ] They tend to occur mostly during perimenopause and postmenopause , the median age having been reported to be about 52 years, and they are rare in children . [ 1 ]
Ovarian germ cell tumors (OGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad, which accounts for about 2.6% of all ovarian malignancies. [1] There are four main types of OGCTs, namely dysgerminomas , yolk sac tumor , teratoma , and choriocarcinoma .
Dental anomalies are among the most recognizable features of ED, with common findings including hypodontia (missing teeth), oligodontia (absence of six or more teeth), and anodontia (complete absence of teeth). Teeth that are present often exhibit unusual shapes, such as conical or peg-like forms, particularly in the anterior regions of the mouth.
Teeth that are affected are primary mandibular molars followed by secondary premolars in the mandible and maxilla, however any teeth may be affected. [6] While no one race is primarily affected, those with conditions that affect bone hormone levels such as Paget's disease and acromegaly are more likely to develop hypercementosis.
As a tooth is forming, a force can move the tooth from its original position, leaving the rest of the tooth to form at an abnormal angle. Cysts or tumors adjacent to a tooth bud are forces known to cause dilaceration, as are primary (baby) teeth pushed upward by trauma into the gingiva where it moves the tooth bud of the permanent tooth.
