[Periodontal diseases--a review on the association between maternal periodontitis and adverse pregnancy outcome]. / Parodontale Erkrankungen--Eine Übersicht über die Beziehung mütterlicher Parodontitis und negativer Schwangerschaftsergebnisse.

Several prospective clinical trials have indicated an association between maternal periodontal status and adverse pregnancy outcome, e.g., low birth weight, pre-term birth and pre-eclampsia. However, the translation of these findings into clinical care and decision making is still a matter of debate. Gynecologists and obstetricians are usually not very familiar with periodontal diseases and do not always consider this pathology in routine preconception counselling. This article outlines the clinical pictures of the most common periodontal diseases and thus helps the gynecologists to identify patients with periodontal diseases.

[The glandular odontogenic cyst--a rare entity]. / Glanduläre odontogene Zyste - eine seltene Entität.

In this short communication, the very rare glandular odontogenic cyst (GOC) is presented as an independent entity. The GOC is a jawbone cyst of the maxilla and mandible. The typical radiological and histopathological characteristics of the GOC are described. Furthermore, differential diagnoses, current treatment options and the recurrence rates of this of entity are discussed.

[An update: keratocystic odontogenic tumor--a cyst to a tumor]. / Update: Keratozystischer odontogener Tumor (KZOT)--Von der Zyste zum Tumor.

According to the 2005 WHO classification of head neck tumors the parakeratinized form of the odontogenic keratocyst (primordial cyst) is listed as benign odontogenic tumor and is classified as keratocystic odontogenic tumor (KCOT). In this short communication the surgical regimen as well as KCOT as an entity are discussed.

Radiographic assessment of a keratocystic odontogenic tumour using cone-beam computed tomography.

BACKGROUND: The keratocystic odontogenic tumour (KCOT), formerly known as the odontogenic keratocyst, is a benign intra-osseous odontogenic tumour. The KCOT is characterised by a potential for locally destructive behaviour and a relatively high recurrence rate. Most KCOT are incidentally discovered as well-defined unilocular or multilocular radiolucencies on routine panoramic radiographs. CASE REPORT: A 15-year-old boy was referred to dental care with a non-syndromic KCOT in the right angle of the mandible. Using cone-beam computed tomography (CBCT) as a diagnostic instrument for precise assessment of the KCOT, the exact location of the lesion was determined. TREATMENT: The cystic formation was enucleated without peripheral ostectomy. FOLLOW-UP: At post-operative follow-up after 3 and 6 months, the boy reported no pain and there was no residual swelling or fracture. Imaging was planned after 1 year to decide whether further surgical treatment is indicated. CONCLUSION: The CBCT is considered beneficial in cases of cystic formations to determine the localisation and borders of the lesion in all three dimensions.
