Cigarette smoking presents oral health professionals with a clinical and research conundrum: reduced periodontal vascular responsiveness to the oral biofilm accompanied by increased susceptibility to destructive periodontal diseases. This presents a significant problem, hampering diagnosis and complicating treatment planning. The aim of this review is to summarize contemporary hypotheses that help to explain mechanistically the phenomenon of a suppressed bleeding response to dysbiotic plaque in the periodontia of smokers. The influence of smoke exposure on angiogenesis, innate cell function, the production of inflammatory mediators including cytokines and proteases, tobacco-bacteria interactions, and potential genetic predisposition are discussed.

“…LDF is spatially limited (1 mm 3 ), and the unknown morphology of the vasculature affects probe placement and subsequently the accuracy of LDF output. LDF outputs are also negatively impacted by head movement of the patient and movement of the hand‐held probe by the operator 78. Contamination of signals from backscatered light on surrounding tissue and/or interference of ambient light together lead to non‐linear output in LDF measures that are difficult to interpret 20…”

Dentists regularly employ a variety of self‐report and sensory techniques to aid in the diagnosis and treatment of tooth‐related disease. Many of these techniques leverage principles borrowed from psychophysics, the quantitative measurement of the relationship between stimuli and evoked sensations, which falls under the larger umbrella of quantitative sensory testing (QST). However, most clinicians fail to meet the bar for what could be considered quantitative sensory testing, and instead focus on qualitative and dichotomous “yes/no” aspects of sensory experience. With our current subjective measurements for pain assessments, diagnosis and treatment of dental pain in young children and individuals (any age) with severe cognitive impairment rely extensively on third‐party observations. Consequently, the limitation of inadequate pain diagnosis can lead to poor pain management. In this review, it discusses mechanisms that underlie acute and chronic dental pain. It details the measurement of somatosensory responses and pulpal blood flow as objective measures of tooth health and pain. It proposes that bridging these varied methodologies will significantly improve diagnosis and treatment of orofacial pain and pathology. It concludes that improving the precision of sensory measurements could yield important improvements in diagnostic challenges in pulpal pathology for noncommunicative and cognitively impaired individuals.

“…13 -16 LDF measurements within the oral cavity differ depending on the anatomical site. 13 Microcirculation of the oral mucosa has not been previously studied in patients with PRP. In the present study, we investigated the association of the frequency of oral cavity lesions with oral microcirculatory dysfunction in patients with PRP in comparison with a healthy control group.…”

INTRODUCTION Primary Raynaud phenomenon (PRP) is the paroxysmal reversible vasoconstrictive reaction of the small vessel arteries and arterioles in response to stress or low temperatures, which cause limited pallor and subsequently cyanosis, as well as redness of the fingers and toes. 1 It can also affect the lips, auricles, nose, and tongue. 2-4 An RP attack may occur at irregular frequencies and lengths, from a single annual episode to multiple times a day, lasting a few minutes to a couple of hours. 5 Primary independent Raynaud phenomenon is not accompanied by an underlying disease, being the direct cause of paroxysmal vasospasm. Between attacks in patients with PRP, physical examination is usually within the normal limits. The incidence of PRP varies
