Objectives: Cancers of the maxillary region are often treated surgically with a maxillectomy followed by rehabilitation involving surgical reconstruction or obturator insertion to improve functional outcomes. However, there is a lack of consensus regarding the specific indications for either rehabilitation method. The objective of this study was to identify unique functional domains for maxillectomy patients who underwent surgical reconstruction or obturator insertion post-op to provide standardized data that can inform selection of either method.

Background And Objectives: Older adults report unmet oral health care needs and barriers in access to care, due in part to provider attitudes and discomfort towards treating older patients. Our study asked: What is known from the literature about the use of undergraduate dentistry programmes to influence dental students' attitudes, perceptions and comfort towards treating geriatric patients? And how can interdisciplinary care facilitate the ability of dentists to work with geriatric patients?

Materials And Methods: A scoping review and stakeholder consultation followed established methodological guidelines. Four databases and two grey literature sources were searched.

Article Synopsis
  • Older adults face significant barriers to accessing oral healthcare, largely due to the reluctance of dental providers to offer geriatric care.
  • Consultations with dental students and faculty in Ontario highlighted various challenges, such as student anxiety and environmental constraints, as well as potential facilitators like supportive learning culture and increased exposure.
  • Overall, both students and faculty expressed support for implementing geriatric dentistry programs to enhance care accessibility, suggesting that pilot initiatives combining effective interventions could be advantageous.

Background: Glaucoma is a progressive optic nerve degenerative disease that often leads to blindness. Local inflammatory responses are implicated in the pathology of glaucoma. Although inflammatory episodes outside the CNS, such as those due to acute systemic infections, have been linked to central neurodegeneration, they do not appear to be relevant to glaucoma.

Optical coherence tomography (OCT) and polarized Raman spectroscopy (PRS) have been shown as useful methods for distinguishing sound enamel from carious lesions ex vivo. However, factors in the oral environment such as calculus, hypocalcification, and stain could lead to false-positive results. OCT and PRS were used to investigate extracted human teeth clinically examined for sound enamel, white spot lesion (WSL), calculus, hypocalcification, and stain to determine whether these factors would confound WSL detection with these optical methods.

A new fibre-optic coupled polarization-resolved Raman spectroscopic system was developed for simultaneous collection of orthogonally polarized Raman spectra in a single measurement. An application of detecting incipient dental caries based on changes observed in Raman polarization anisotropy was also demonstrated using the developed fibre-optic Raman spectroscopic system. The predicted reduction of polarization anisotropy in the Raman spectra of caries lesions was observed and the results were consistent with those reported previously with Raman microspectroscopy.

The demineralization of enamel that is associated with early caries formation affects the optical properties of the enamel. Polarized Raman spectroscopy and optical coherence tomography have been used to detect these changes and potentially offer a means to detect and monitor early caries development. The total optical attenuation coefficient as measured by optical coherence tomography and the polarization anisotropy of the Raman peak arising from the symmetric nu(1) vibration of PO4(3-) at approximately 959 cm(-1) have been demonstrated as being sensitive markers of early caries.

A new technique based on polarized Raman spectroscopy is demonstrated for detecting early dental caries on extracted human teeth. Sound tooth enamel exhibited strong Raman polarization anisotropy whereas early caries consistently showed a lower degree of Raman polarization anisotropy. In particular, for sound enamel, the Raman peak arising from the symmetric nu1 vibration of PO(4) (3-) at 959 cm(-1) is strongly polarized.

Early dental caries detection will facilitate implementation of nonsurgical methods for arresting caries progression and promoting tooth remineralization. We present a method that combines optical coherence tomography (OCT) and Raman spectroscopy to provide morphological information and biochemical specificity for detecting and characterizing incipient carious lesions found in extracted human teeth. OCT imaging of tooth samples demonstrated increased light backscattering intensity at sites of carious lesions as compared to the sound enamel.

Purpose: There have been anecdotal reports of low bond strength with autocured resin composite materials, particularly when light-cured bonding agents that combine primer and adhesive in a 1-bottle preparation are used. The objective of this study was to determine if the mode of polymerization of the bonding agent influences the strength of the attachment of autocured resin composite luting cements to dentin.

Methods: The shear bond strength of 2 resin luting cements, Calibra and RelyX ARC, polymerized by autocuring, in combination with 4 different bonding agents, Scotchbond Multipurpose Plus, Prime & Bond NT, IntegraBond and Single Bond, polymerized to bovine dentin by light-curing, autocuring or dual-curing, was determined.
