Florid cemento-osseous dysplasia: A case report.

Cemento-osseous dysplasia is non-neoplastic, reactive fibro-osseous lesions that affect the tooth-bearing areas of the jaws. Osseous dysplasia is further divided into three subtypes: Periapical osseous dysplasia, focal osseous dysplasia, and florid osseous dysplasia. We hereby, present a case of florid cemento-osseous dysplasia occurring in a 40-year old dentulous Indian woman. The patient presented with lesions involving the mandibular right and left quadrant.

Postoperative maxillary cyst.

Cysts of the oral cavity are among the most commonly encountered biopsy specimen in histopathology. Shear categorized the cysts associated with maxillary antrum under four subheadings - mucocoele, retention cyst, pseudocyst, and postoperative maxillary cyst (PMC). PMC is also known as surgical ciliated cyst, postoperative paranasal cyst, or respiratory implantation cyst. Although it constitutes 20% of oral cysts in Japan, it is quite rare in the other parts of the world. Herewith, we report a case of a 65-year-old female who presented with the complaint of palatal swelling and having a history of maxillary sinus surgery 30 years ago.

Prevalence of Ponticulus Posticus on Lateral Cephalometric Radiographs, its Association with Cervicogenic Headache and a Review of Literature.

OBJECTIVES: The aim of this study was to calculate the prevalence of ponticulus posticus (a small bony bridge on the dorsal aspect of the atlas on lateral digital cephalometric radiographs) and classify it into a complete ring or an incomplete ring. The study also investigated its association with the presence or absence of cervicogenic headache in the examined population; a literature review of ponticulus posticus is also presented. METHODS: The presence and types of ponticuli posticus were investigated on 500 digital lateral cephalograms and the same patients were questioned for a history of cervicogenic headache. RESULTS: In 500 patients, 79 ponticulus posticus (34 complete and 45 incomplete) were identified on the lateral cephalograms; therefore, the prevalence was 15.8%. The distribution of the type of ponticulus posticus was 13.1% in males and 17.9% in females in the studied sample. The overall prevalence of cervicogenic headache was 6% in the studied sample with a significant association between cervicogenic headache and type of ponticulus posticus. CONCLUSIONS: The study shows that ponticulus posticus is not a rare finding and its association with unexplainable headache, neck pain, and other symptoms as well as its importance and implications during management of cervical spine surgical procedures, especially those requiring lateral mass screw placements in the atlas, imply that radiologists and dentists in general should closely inspect the vertebral region on a lateral cephalogram.
