Dietary intake in edentulous subjects with good and poor quality complete dentures.

Statement Of Problem: Previous studies in complete denture wearers evaluated the relationship between diet and measures of chewing, yet only isolated nutrient intake was considered. This limited information makes the assessment of overall diet quality and the planning of interventions difficult.

Purpose: This study investigated the relationship of complete denture quality to masticatory performance, perceived ability to chew, and diet quality as measured by the Healthy Eating Index (HEI), an overall diet quality index.

Readiness for orthognathic surgery: a survey of practitioner opinion.

The purpose of this study was to determine if a general consensus exists among orthodontists regarding the features of an adequate presurgical setup. A questionnaire was developed to assess the importance of 12 criteria for surgical readiness. Each criterion was rated on a 5-point scale (1 = Unimportant, 5 = Critical).

Psychological distress in childhood trauma survivors who abuse drugs.

The relationships between the level of childhood maltreatment and current psychological distress were examined in a community sample of 676 substance abusing men and women using a validated self-report instrument (the Childhood Trauma Questionnaire) designed to measure physical, emotional, and sexual abuse and physical and emotional neglect. Current levels of self-reported psychological distress/symptoms were measured using a 53-item Brief Symptom Inventory. Prevalence of early trauma ranged from 44% for emotional neglect to 65% for sexual abuse.

Severity, distribution, and correlates of occlusal tooth wear in a sample of Mexican-American and European-American adults.

Purpose: The objective of this study was to determine the severity, distribution, and correlates of tooth wear in a sample of Mexican-American and European-American adults drawn from a community-based longitudinal aging study on oral health.

Materials And Methods: The maxillary teeth of 71 subjects enrolled in a longitudinal aging study were assessed using a previously introduced five-point (0 to 4) ordinal scoring system in which each tooth is given a score describing the severity of wear. The tooth wear scores were compared with data concerning demographic factors, functional/parafunctional habits, soft drink consumption, and bite force measurements to determine specific correlates of tooth wear.

The current status of psychological assessment training in graduate and professional schools.

Test-based psychological assessment is threatened by the policies of managed care organizations; however, research has demonstrated that test-based psychological assessment is quite valuable and economically justified when conducted by well-trained psychologists. This surfaces the question of the current status of graduate training in test-based psychological assessment. Results of this study indicate that clinical and counseling students currently receive almost equivalent training in test-based assessment.

Oral function and diet quality in a community-based sample.

Overall diet quality indices, such as the Healthy Eating Index (HEI), are preferred for epidemiological studies, yet studies in dentistry have focused on isolated dietary components. This study investigated the influence of socio-demographic and masticatory variables (masticatory performance, bite force, number of posterior functional tooth units, TMJ disorder, and dentition status) on overall diet quality in a community-based sample (n = 731). Cross-sectional data were derived from clinical examinations, bite force recordings, masticatory performance measurements, and two 24-hour dietary recalls.

Determinants of masticatory performance in dentate adults.

Masticatory performance results from a complex interplay of direct and indirect effects, yet most studies employ univariate models. This study tested a multivariate model of masticatory performance for dentate subjects. Explanatory variables included number of functional tooth units, bite force, sex, age, masseter cross-sectional area, presence of temporomandibular disorders, and presence of diabetes mellitus.

Psychosocial predictors of satisfaction among orthognathic surgery patients.

This study assessed the usefulness of selected psychosocial tests and demographic measures in identifying satisfied versus dissatisfied patients who received orthognathic surgery. Data were collected prior to placement of orthodontic appliances, 1 to 2 weeks presurgery, and at 1 week, 8 weeks, 6 months, 12 months and and 2 years postsurgery. The Revised Symptom Checklist-90 (SCL-90-R) scales, the Eysenck Personality Inventory (EPI), the Sickness Impact Profile (SIP), and the Oral Health Status Questionnaire (OHSQ) were used as independent variables.

Positional change of the hyoid bone after bilateral sagittal split osteotomy with rigid and wire fixation.

The purpose of this study was to compare positional changes of the hyoid bone and the amount of postsurgical compensation in mandibular position in patients who received either wire or rigid fixation after surgery. Data were analyzed from 97 patients (25 males and 72 females) who were randomized to receive wire (43) or rigid (54) fixation after mandibular advancement surgery as part of a multicenter clinical trial. Radiographs were digitized before surgery (T2), immediately after surgery (T3), and 8 weeks (T4), 6 months (T5), 1 year (T6), and 2 years (T7) after surgery.

Is use of exogenous estrogen associated with temporomandibular signs and symptoms?

Background: Studies of historical data suggest a link between exogenous estrogen use and referral for treatment for temporomandibular disorders, or TMDs. The purpose of the authors' study was to determine the association between exogenous estrogen use and signs and symptoms of TMD assessed by direct physical examination in a randomly selected community sample of primarily postmenopausal women.

Methods: A calibrated clinical examiner examined a stratified random sample of 510 women aged 37 to 82 years using the Craniomandibular Index, or CMI.

Mandibular range of motion after bilateral sagittal split ramus osteotomy with wire osteosynthesis or rigid fixation.

Objectives: An analysis was conducted to compare mandibular range of motion among Class II patients treated with wire osteosynthesis or rigid internal fixation after surgical mandibular advancement.

Study Design: Patients randomly received wire osteosynthesis and 8 weeks of maxillomandibular fixation (n = 49) or rigid internal fixation (n = 78). Mandibular range of motion was measured 2 weeks before surgery and 8 weeks, 6 months, and 1, 2, and 5 years after surgery.

Combined effects of estrogen and progesterone on the anterior cruciate ligament.

Previous studies from the authors' laboratory have established the presence of estrogen and progesterone receptors in the human anterior cruciate ligament. The purpose of the current study was to investigate the combined effects of 1beta-estradiol and progesterone on cell proliferation and procollagen synthesis of the human anterior cruciate ligament fibroblasts. Fibroblast proliferation and procollagen synthesis in response to logarithmic concentrations of 17beta-estradiol (0.

Comparison of MRI and radiographs in the evaluation of acromial morphology.

This study compared the accuracy of magnetic resonance imaging (MRI) grading of acromions using supraspinatus outlet view radiographs. Thirty-two consecutive patients (17 men and 15 women) treated for shoulder disorders were included in the study. Average patient age was 58.

Relationship between oral function and occlusal support in denture wearers.

Patients with removable partial dentures or complete dentures do not demonstrate masticatory function to the same level as patients with a full set of natural teeth. The purpose of this study was to characterize the relationship between reduction of masticatory function, in terms of masticatory performance and bite force, and the existence of remaining natural occlusal supports as assessed by the Eichner index. One hundred and eighteen removable partial denture and complete denture wearers were selected for analyses.

Association of salivary flow rates with maximal bite force.

Mean salivary secretion and bite force decrease with advancing age. Previous studies have shown that salivary flow rates are influenced by mastication. In the present study, we examined the relationship between salivary flow rates and maximal bite force in a community-based sample of men and women 35 years of age or older.

Patients' own reasons and patient-perceived recommendations for orthognathic surgery.

In an attempt to learn more about patients' decision-making processes, an analysis was performed to examine patients' reasons for undergoing orthognathic surgery and their understanding of the reasons surgery was recommended. Before surgery, 105 females and 38 males completed an open-ended questionnaire in which they listed their reasons for choosing orthognathic surgery and their perceptions of their orthodontists' recommendations. Three raters classified the responses into 7 categories: esthetics, psychosocial, functional, TMJ/pain, authority, prevention, and other.

Psychosocial predictors of high-risk patients undergoing orthognathic surgery.

The purpose of this analysis was to identify a set of predictor variables that are prospectively related to postsurgical outcomes. Specifically, psychosocial characteristics were sought to predict postsurgical outcomes. The 5 Revised Symptom Checklist-90 (SCL-90-R) scales, the neuroticism score of the Eysenck Personality Inventory (EPI), the psychosocial domain score from the Sickness Impact Profile (SIP), and 4 scales from the Oral Health Status Questionnaire (OHSQ) were used as the predictors.

Bilateral sagittal split osteotomy and temporomandibular disorders: rigid fixation versus wire fixation.

Objective: The effects of orthognathic surgery on temporomandibular disorders may be related to the surgical method that is used. Specifically, it has been suggested that the choice of stabilization technique may play a major role in the functional outcome of mandibular advancement surgery. The purpose of this study was to prospectively compare long-term (2 years) signs and symptoms of temporomandibular disorders after orthognathic surgery with bilateral sagittal split osteotomy in 127 patients randomized to receive rigid or wire fixation.

Effect of estrogen on cellular metabolism of the human anterior cruciate ligament.

Previous studies from this laboratory have established the presence of estrogen receptors in the human anterior cruciate ligament. The purpose of this study was to investigate the effects of 17 beta-estradiol on cell proliferation and procollagen levels, as an indicator of collagen synthesis, in the human anterior cruciate ligament fibroblasts. Fibroblast proliferation and procollagen synthesis in response to near log concentrations of 17 beta-estradiol (at 0.

Cervical flexion and extension radiographs in acutely injured patients.

Flexion and extension lateral radiographs of the cervical spine may suggest signs of ligamentous and soft tissue injuries in a potentially unstable spine. However, patients with acute injuries and severe pain and muscle spasms may not be able to move their necks effectively, severely compromising the diagnostic yield of the radiographs. In addition, there are reports of serious neurologic injuries occurring with the use of these radiographs in acutely injured patients.

Histories of childhood trauma and the effects on risky HIV behaviors in a sample of women drug users.

A cross-sectional study was conducted to examine the association between childhood trauma and current human immunodeficiency virus (HIV) risk behaviors of 181 active illicit-drug-using women in San Antonio, Texas. We found very few statistically significant associations, which could he explained by (a) childhood trauma subtypes not being mutually exclusive, (b) clustering of mild-to-severe forms of abuse. and (c) childhood trauma having an indirect, rather than direct, effect on HIV risk behavior.

Prevalence of childhood trauma in a community sample of substance-abusing women.

The purpose of this study was to estimate the prevalence of positive trauma histories in a community sample of intravenous drug using (IVDU) women for five subsets of childhood trauma (emotional abuse or neglect, physical abuse or neglect, and sexual abuse) and to compare demographic variables between the abused versus nonabused groups. Of the 181 women who completed the Childhood Trauma Questionnaire (CTQ), 109 (60.2%) were sexually abused, 100 (55.

Does chewing performance depend upon a specific masticatory pattern?

The purpose of this article is to review the literature concerning the ideal chewing pattern for best chewing performance. We conclude that at this time there is not one ideal chewing pattern which can be used clinically or in research to assess the health of the mastication apparatus nor to predict chewing performance. It is clear that human masticatory behaviour is one of the most complex human behaviours.
