It illustrates a typical recording of the blood flow as indicated by changes in the amplitude of the blood volume pulse (BVP) of the gingival papilla, recorded simultaneously with digital BVP and other physiological variables. The chapter describes the parameters in response to a standard physiological stress, such as the cold pressor test for 21 subjects. During cold pressor stimulation, apparent vasoconstriction of both papilla and finger is associated with decreased propagation time and increased crest time. This technique has been utilized to differentiate patients with oral disease, such as acute necrotizing ulcerative gingivitis or trench mouth from healthy controls. The chapter discusses monitoring of the circulation of the periodontal ligament by insertion of the probe through root canals.

Thus, this study by O'Neill et al provides a timely, well-controlled clinical trial of 2 procedures used to treat Class II Division 1 malocclusion. Consistent with the new philosophy of evidence-based dentistry, children were randomly assigned to the control (untreated), Fränkel, or Harvold groups. To minimize distracting influences of complexion, hair color and style, facial expression, etc, profile images were reduced to silhouettes. Panels of parents, art students, and dental students compared the attractiveness of pretreatment and posttreatment silhouettes with silhouettes of untreated controls produced over the same time period. Although the data suggest possible increases in attractiveness for the 2 treatment groups, the differences are not statistically significant, primarily because of the extremely high variances (SD 2) in all respondent groups. Although the reliability of the judgments is extremely high, the validity of the endpoints may be questioned. The visual analog scale was anchored with examples of very attractive, average, and very unattractive images selected by only 2 orthodontists. In agreement with other studies, the authors acknowledge that the physical bases of perceiving a face as attractive or unattractive differ widely among judges from orthodontic standards. 3 The issue is also complicated by the necessary assumption for parametric statistical analysis that the intervals on the visual analog scale are subjectively equal. From that assumption, the authors might have considered the use of stan

The type of treatment, number of assistants, and patient education methods appear to affect the total number of patients treated. The solution to efficient work space may be in an analysis of goals and the tailoring of the operatory and equipment to meet individually established requirements.

To avoid the possibility of interdisciplinary semantic confusion spoiling the honeymoon of behavi... more To avoid the possibility of interdisciplinary semantic confusion spoiling the honeymoon of behavioral science and dentistry, it is essential at the outset to define the terms "psychophysiology" and "oral cavity." Psychophysiology has been defined by Stern' as dealing with manipulation of behavioral events and recording of physiologic variables in contrast to physiologic psychology, which is the manipulation of physiologic variables and recording of behavioral events. As for the oral cavity, it seems reasonable that with the possible exception of the reproductive system, a portion or prototype of most all body systems may be found within the mouth or surrounding structures. Even the reproductive system, however, has been included by the psychiatrists. For example, one finds the nervous system, including somatic sensory and motor components and afferent and efferent autonomic representatives; portions of the respiratory and digestive system; the musculoskeletal system, affecting the temporomandibular joint, mastication, and occlusion; and, perhaps less specifically, the cardiovascular and endocrine systems, although in recent years both of these systems have been shown to be more directly involved in the pathophysiology of oral disease. It also follows that each of these systems is structured and functions in the healthy state in accordance with well-known biological principles included in the disciplines of anatomy, biochemistry, physiology and, in the diseased state, functions in accordance with the principles of pathology, bacteriology, immunology, and pharmacology. To the extent that these systems are influenced by the central nervous system, they will be affected by variations in the psychological status of the organism. The corollary follows that noxious environmental events, acting through the senses and the central nervous system, have as much potential to produce

Participants were non-elderly patients with major depressive disorder (MDD). We assessed subjective cognition using the Perceived Deficit Questionnaire for Depression (PDQ-D) and objective cognition using Face I and Face II tests of the Wechsler Memory Scale, 3rd edition and Digit Span and Matrix Reasoning tests of the Wechsler Intelligence Scale for Adults, 3rd edition. The discrepancy between objective and subjective cognition was estimated. Participants were 57 outpatients with MDD. PDQ-D scores were not correlated with composite neurocognitive test (NCT) z scores. Years of education significantly predicted composite NCT z scores, as did age. The 9-item Patient Health Questionnaire (PHQ-9) scores significantly predicted PDQ-D scores, as did antidepressant treatment. Age significantly predicted discrepancy scores, as did PHQ-9 scores. In conclusion, objective and subjective cognition in patients with MDD are not correlated. Age and education predict objective cognition. Depression. severity and antidepressant treatment predict subjective cognition. Age and depression severity may predict the discrepancy between objective and subjective cognition. Cognition is a generic term embracing the mental activities associated with thinking, learning, and memory 1. Cognitive dysfunction is common in depressed patients. While 'hot' cognitive dysfunction implies a cognitive bias toward negative information and a misinterpretation of social cues, 'cold' cognitive dysfunction is the functional impairment of information process in the absence of any emotional influence 2. Hot cognitive dysfunction is highly correlated with depression and may contribute to the perpetuation of negative emotional states in MDD 3. Depressed patients perform neurocognitive or cold cognitive tests poorer than healthy controls in many areas 4. In addition, they also have more cognitive complaints than non-depressed patients 5. Several lines of evidence have shown that neurocognitive and perceived cognitive dysfunction in depressed patients is associated with functional disability and adverse outcomes 6-8. Not only objective but also subjective cognition is of concern for depressed patients. Up to 81% of patients with MDD may have subjective cognitive dysfunction, e.g., memory or concentration complaints 8. As a diagnostic criterion for major depressive disorder, not only objectively but also subjectively diminished ability to think, as well as concentrate, or indecisiveness can be observed 9. Recent evidence suggests that subjective cognitive dysfunction more closely relates with functioning than an objective dysfunction 10. Subjective cognition in depressed patients remains unclear. Growing evidence has raised questions regarding the correlation between objective and subjective cognition 11, 12. While an earlier study did not find the correlation between subjective cognitive dysfunction and functional disability 13 , two recent studies found such an association 11, 14. Studies on the predictors of objective and subjective cognition, as well as their discrepancy, would be helpful to clarify the similarity and/or distinction between objective and subjective cognition in depressed patients. In this study, we proposed to: i) determine the correlation between objective and subjective cognition, ii) examine the socio-demographic and clinical correlates of objective or subjective cognition and iii) identify the predictors of discrepancy between objective and subjective cognition. Methods Participants in this study were a subgroup of those taking part in 'The Study of Cognitive Dysfunction in Asians with Depression' or CogDAD study 15.

I have a DMD (Doctor of Dental Medicine, Dentariae Medicinae Doctor), followed by a PhD (in psychology). In Germany I would be referred to as ‘Doctor Doctor’, and when I served as a professor in the Netherlands, I was called ‘Professor Doctor Doctor’. It did not matter whether I was a physician, surgeon, podiatrist, veterinarian, dentist, and/or psychologist. In several places in the two publications the authors take umbrage at the very idea that dentists should be called doctors. For example, in the article by Ibery et al., ‘Do surgeons wish to become doctors?’, the authors state, ‘dental surgeons in general dental practice, who also hold a bachelors degree, are now styling themselves Dr. We are uncertain as to the origin of this creeping doctorization’. To compound the insult, you separate doctors from dentists in your comparisons, rather than referring to them as physicians and dentists, who are both called doctor in the USA and elsewhere. Even that distinction would become blurred if the change being proposed by the Commonwealth of Massachusetts legislature to redesignate dentists as oral physicians comes to pass.

Twenty-two students were found who had ANUG at the time of matriculation, had a history of ANUG or contracted ANUG during their freshman year. This group smoked more than the unaffected group. The data also suggested that poor oral hygiene might be a factor in the disease. That there is a psychological fac tor in the disease is suggested by the greater number of withdrawals from col lege and the higher proportion of psy chology majors in the ANUG group than in the unaffected group.

In previous research, left-sided spinal pain was more frequent and associated with greater emotional distress and healthcare use than right-sided pain. We hypothesized therefore that patients with left-sided head pain might experience higher levels of distress or healthcare use than those with right-sided or bilateral pain. Medical record information was extracted for 477 randomly selected patients with migraine seen in 2011 in a tertiary headache clinic. This included demographic data, pain location, handedness, comorbid psychiatric diagnoses, medical and emergency department visits, and use of selected headache medications. Two hundred twenty-eight of four hundred seventy-seven (47.8%) patients reported lateralized pain, of which 107 (47.9%) patients were right sided compared with 65 (28.5%) left-sided patients (=0.001), while 56 (24.5%) reported unilateral pain with no side predominance. Contrary to expectations, with the...

METHODS Following the fabrication of splints thicker than those conventionally used, the effectiveness of this new procedure used by dentists was determined by comparing the self-reported frequency and intensity/severity of PTSD symptomatology during a seven-night pretreatment baseline period without the splint with a second seven-night period in which the modified splint was inserted. The scoring for the three dependent measures (sleep disruptions, headaches, and nightmares) was based on the frequencies on a scale from 0-7 multiplied by the intensity/severity on a scale of 1-10. RESULTS Compared with the pre-splint baseline period, the insertion of the thickened splint resulted in a highly significant reduction of sleep disruption, nocturnal headaches, and nightmares. A second seven-night control period without the splint was followed by a second seven-night period with the splint, reproducing the effectiveness of the first splinting period. CONCLUSION The results of this study provide the first systematic, documented proof of concept of the effectiveness of a modified splinting procedure in reducing key nocturnal symptoms in PTSD patients.

METHODS Following the fabrication of splints thicker than those conventionally used, the effectiveness of this new procedure used by dentists was determined by comparing the self-reported frequency and intensity/severity of PTSD symptomatology during a seven-night pretreatment baseline period without the splint with a second seven-night period in which the modified splint was inserted. The scoring for the three dependent measures (sleep disruptions, headaches, and nightmares) was based on the frequencies on a scale from 0-7 multiplied by the intensity/severity on a scale of 1-10. RESULTS Compared with the pre-splint baseline period, the insertion of the thickened splint resulted in a highly significant reduction of sleep disruption, nocturnal headaches, and nightmares. A second seven-night control period without the splint was followed by a second seven-night period with the splint, reproducing the effectiveness of the first splinting period. CONCLUSION The results of this study provide the first systematic, documented proof of concept of the effectiveness of a modified splinting procedure in reducing key nocturnal symptoms in PTSD patients.
