Diagnosis And Management Of Nasopalatine Duct Cyst: A Report Of Two Cases And Literature Review, Feiyi Sun Dds, Harry Dym Dds

The New York State Dental Journal

The nasopalatine duct cyst (NPDC) is one of the most common non-odontogenic, non-neoplastic developmental cysts. It arises from the epithelial remnants of the nasopalatine duct within the incisive canal and crosses the midline of the anterior maxilla. Most cases are asymptomatic and either are discovered by chance on radiographs or present as a soft tissue swelling, pain, or drainage in the palate. The present study describes the diagnosis and surgical management of two NPDC cases at the Department of Oral and Maxillofacial Surgery at the Brooklyn Hospital Center.

Dentistry And The Law: How Does An ‘Assignment Of Benefits’ Work?, Dan Schulte Jd

The Journal of the Michigan Dental Association

The use of an assignment of benefits form in dental practice is explored in this article, with a focus on its potential benefits and limitations. This form allows patients to assign their dental plan benefits to the provider, enabling direct payment for services. However, its acceptance by dental plans varies and is often subject to state and federal regulations. While assignment of benefits offers a pathway to independent fee setting and potential billing for any balance exceeding benefits, legal and regulatory considerations must be addressed to fully implement this approach.

Space Maintenance In The Primary And Mixed Dentitions, Giovana Anovazzi Medeiros Dds, Msc, Phd, Chia-En Tsai Dds, James R. Boynton Dds, Ms

The Journal of the Michigan Dental Association

Primary teeth serve many critical functions in the growing child: they allow for proper chewing function for appropriate diet and nutrition, help in speech production and development, promote self-esteem, and importantly preserve space for eruption of the succedaneous permanent dentition. Premature loss of a primary molar can cause a loss of arch perimeter and negatively impact the normal eruption path of premolars. Space maintenance is an approach to minimize or prevent untoward consequences after unavoidable loss of a primary molar. Several types of space maintainers can be used to preserve arch length, including fixed unilateral space maintainers, such as the …

Evaluating Repeated Dental Emergency Visits Related To Third Molar Pathologies In An Urgent Dental Care Center, Armando U. Rivera Dds, Linda Rasubala Dds, Phd, Gilbert H. Schulenberg Dds, Changyong Feng Phd, Hans Malmstrom Dds, Yan-Fang Ren Dds, Mph, Phd

The New York State Dental Journal

Individuals with symptomatic third molar pathologies frequently seek dental care at emergency departments or urgent dental care centers. This is becoming a dental public health problem, when repeated dental emergency appointments are sought for treatment of symptomatic contralateral wisdom teeth. Body: We designed a retrospective review study of adults 18 years and older with an initial dental emergency visit related to third molar pathology at a single dental urgent care center, at the University of Rochester. Conclusion: A sub-optimal oral health is a predictor for future emergency dental visits, due to pathology of remaining third molars.
