Sialosis, Gout Induced or Idiopathic? Case Report.

J Oral Maxillofac Surg

February 2017

Director, Salivary Gland Center; Associate Dean and Clinical Professor, Department of Oral and Maxillofacial Surgery, College of Dental Medicine, Salivary Gland Center, Columbia University College of Dental Medicine, New York, NY. Electronic address:

Sialosis is observed in relation to diabetes, alcoholism, and malnutrition. An assumed relation between gout and sialosis is probably based on confusion that originated from the therapeutic use of phenylbutazone for gout and the sialadenitis that the medication caused. This report describes a case of sialosis in a patient with a longstanding history of gout that was idiopathic in origin.

Modeling Social Capital as Dynamic Networks to Promote Access to Oral Healthcare.

Soc Cult Behav Model (2016)

January 2016

Department of Geography, University at Buffalo, The State University of New York, 105 Wilkeson Quad, Buffalo, NY 14261, USA.

Social capital, as comprised of human connections in social networks and their associated benefits, is closely related to the health of individuals, communities, and societies at large. For disadvantaged population groups such as older adults and racial/ethnic minorities, social capital may play a particularly critical role in mitigating the negative effects and reinforcing the positive effects on health. In this project, we model social capital as both cause and effect by simulating dynamic networks.

Simultaneous Bilateral Hypertrophies of the Parotid Gland and Masseter Muscle: Case Report.

J Oral Maxillofac Surg

January 2017

Director, Salivary Gland Center; Associate Dean and Clinical Professor, Department of Oral and Maxillofacial Surgery, Columbia University College of Dental Medicine, New York, NY. Electronic address:

Increased salivary demand can lead to enlarged parotid salivary glands, and increased activity of the masseter muscles can cause masseter hypertrophy. This report describes a most unusual case of simultaneous bilateral hypertrophies of the parotid gland and masseter muscle originating from the very extensive habit of chewing gum. An extensive literature review uncovered many cases of the independent existence of masseteric or parotid hypertrophy, but no example of the simultaneous occurrence of these 2 conditions.

Leukoplakia is the most common precursor lesion of oral squamous cell carcinoma (OSCC). Currently, the risk of progression to OSCC is assessed based on histopathologic examination alone. However, this method fails to identify the subset of microscopically innocuous leukoplakia that ultimately transforms to OSCC.

Tissue-engineered autologous grafts for facial bone reconstruction.

Sci Transl Med

June 2016

Department of Biomedical Engineering, Columbia University, 500 West 120th Street, New York, NY 10027, USA.

Facial deformities require precise reconstruction of the appearance and function of the original tissue. The current standard of care-the use of bone harvested from another region in the body-has major limitations, including pain and comorbidities associated with surgery. We have engineered one of the most geometrically complex facial bones by using autologous stromal/stem cells, native bovine bone matrix, and a perfusion bioreactor for the growth and transport of living grafts, without bone morphogenetic proteins.

Clinical Decisions: Determining When to Save or Remove an Ailing Implant.

Compend Contin Educ Dent

April 2016

Clinical Associate Professor, Department of Periodontics, Columbia University College of Dental Medicine, New York, New York.

The basis for the decision to either save or remove an ailing implant is multifactorial, and, as such, it has become one of the more controversial topics in the field of dental implantology. While bone lost to peri-implant disease can now be augmented with increasing predictability, the degree of success still varies depending on the size and configuration of the osseous defect. Concurrently, with the development of improved high-reverse torque instrumentation, minimally invasive techniques can be used to easily remove an implant that is malpositioned, causing an esthetic problem, or showing advanced bone loss.

Infection and Pulp Regeneration.

Dent J (Basel)

March 2016

Division of Endodontics, Columbia University College of Dental Medicine, 630 W. 168th St. PH7Stem #128, New York, NY 10032, USA.

The regeneration of the pulp-dentin complex has been a great challenge to both scientists and clinicians. Previous work has shown that the presence of prior infection may influence the characteristics of tissues formed in the root canal space after regenerative endodontic treatment. The formation of ectopic tissues such as periodontal ligament, bone, and cementum has been observed in the root canal space of immature necrotic teeth with apical periodontitis, while the regeneration of dentin and pulp has been identified in previously non-infected teeth.

The secondary cartilage of the mandibular condyle is unique as it undergoes endochondral ossification during growth and robustly remodels in response to changes in its mechanical loading environment. This cartilage is derived from mesenchymal progenitor cells that express markers of early osteoblast differentiation, namely alkaline phosphatase (ALP) and runt-related transcription factor 2 (Runx2). Interestingly, these progenitor cells then differentiate into cartilage with appropriate mechanical loading.

Article Synopsis
  • Obesity influences bone health through altered lipid metabolism and bone homeostasis.
  • In a study using mice, a high-fat diet with palmitic acid led to greater alveolar bone loss when exposed to the bacteria Porphyromonas gingivalis, compared to oleic acid or normal diets.
  • Elevated palmitic acid was linked to higher inflammation levels and decreased bone metabolism, emphasizing the role specific fatty acids play in bone health during periodontal disease.

Studies conducted over the past 25 years have focussed on the role of periodontitis, an inflammatory condition of microbial aetiology that destroys the tooth-supporting tissues, as a systemic inflammatory stressor that can act as an independent risk factor of atherosclerotic vascular disease (AVSD) and adverse pregnancy outcomes (APOs). It has been suggested that periodontitis-associated bacteraemias and systemic dissemination of inflammatory mediators produced in the periodontal tissues may result in systemic inflammation and endothelial dysfunction, and that bacteria of oral origin may translocate into the feto-placental unit. Epidemiological studies largely support an association between periodontitis and ASVD/APOs, independently of known confounders; indeed, periodontitis has been shown to confer statistically significantly elevated risk for clinical events associated with ASVD and APOs in multivariable adjustments.
