Bacterial colonies, foreign bodies or other artifacts in tonsil specimens are identified as incidental findings. Actinomyces are relatively often encountered on histological examination of tonsils. Actinomyces israeli and Actinomyces naeslundi are the most frequently isolated pathogenic Actinomycetes. They are Gram positive, anaerobic, non acid fast, branching, filamentous and slow growing bact...

The nasopalatine cyst is the most common epithelial and nonodontogenic cyst of the maxilla. The cyst originates from epithelial remnants from the nasopalatine duct. The cells may be activated spontaneously during life or are eventually stimulated by the irritating action of various agents (infection, etc.). It is different from a radicular cyst. The definite diagnosis should be based on clinica...

Actinomycosis is a rare anaerobic bacterial infection typically caused by Actinomyces israelii. Although part of normal flora in the oral cavity, and respiratory and digestive tracts, A israelii can give rise to pathologic infections most commonly reported in the oral cavity from odontogenic causes. We present a rare case of invasive actinomycosis presenting with extensive midface destruction i...

Odontomas are categorised into mixed odontogenic tumor that originates ecto-mesenchymally and made up of mineralised tissue. Hamartoma is the most frequent benign tumour with an aetiology. It distinguished by its sluggish growth lack aggression. "Erupted odontomas" those erupt oral cavity uncommon. They usually noticed in regular radiography can be caused a variety factors, including trauma, ge...

We report the simultaneous rehabilitation of an edentulous patient with a hybrid (zygomatic and conventional implants) all-on-four implant-supported prosthesis for the maxilla and a standard (conventional implants) all-on-four implant-supported prosthesis for the mandible. The transfer impression was made with a multifunctional guide and the upper and lower prostheses were placed 24h postoperat...

a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...

introduction juvenile ossifying fibroma is a benign, bone-forming neoplasm with aggressive local growth that is distinguished from other fibro-osseous lesions primarily by its age of onset, clinical presentation and aggressive behavior. although a benign entity, juvenile ossifying fibroma is known to be locally aggressive and has a high tendency to recur. two distinctive microscopic patterns ha...
