Predicting Group‐Based Trajectories of Oral Health‐Related Quality of Life From Late Adolescence to Early Adulthood Using K‐Means Clustering Algorithm
Most participants followed a favorable OHRQoL trajectory and were from higher socioeconomic backgrounds. These findings highlight the value of longitudinal, multi-measure approaches in identifying at-risk subgroups
Factors Associated With Dentists' Intent to Stay Long‐Term at Their Current Community Health Center
The study underscored the importance of dentists' autonomy and role in their intent to remain at CHCs. Factors typically associated with recruitment packages or length of time in clinical practice were not significantly associated with intent to stay. Distinguishing between recruitment and retention strategies is crucial for CHCs to fulfill their mission of ensuring equitable dental care access
Associations between longitudinal fluoride intakes from birth to age 23 and multi‐row detector computed tomography bone densitometry outcomes at age 23
Longitudinal fluoride intakes had little association with bone measures at age 23. As there were no adverse effects from fluoride intake on bone health in young adults, results support the continued use of fluorides, particularly community water fluoridation is the most cost-effective method of dental caries prevention
Dietary questions in caries risk assessment and their relationship to caries
Specific and focused questions on dietary practices are strongly associated with caries, and may be useful in improving caries risk assessments
Dental caries incidence and associated factors in young adults
The incidence of caries from age 17 to 23 in this study was low. This study suggests and reinforces the need to continue to advocate for caries preventive strategies such as fluoride use, encouraging milk intake, and reducing sugar-sweetened beverage intakes
Patterns of fluoride intake from 6 to 17 years of age: The Iowa Fluoride Study
Daily mean fluoride intakes from single and combined sources were relatively stable, while the intake of fluoride per kg bw decreased from 6 to 17 years of age. Fluoridated water was the major source of ingested fluoride, contributing over 50% of total daily intake at all ages
Prevalence of non‐cavitated lesions and progression, regression, and no change from age 9 to 23 years
Non-cavitated lesions were more prevalent at age 17 than at ages 9, 13, and 23. The high rates of regression compared to progression or no change suggest that many non-cavitated lesions do not progress to cavitated lesions and could be reversed; therefore, surgical intervention should not be the treatment of choice for incipient lesions
Identification of and Associations among Low, Middle, and High Body Composition Trajectories from Age 5- to 17-Years
Our objective was to identify sex-specific age 5- to 17-year body composition (body mass index (BMI), % body fat, fat mass index, fat-free mass index) trajectories, compare trajectories assigned using age 5 (AGE5) data to those assigned using all available (ALL) data, and compare BMI assignments to other body composition assignments. Cluster analysis was used to identify low, medium, and high trajectories from body composition measures obtained f…
Dental caries treatment completed under general anesthesia among American Indian children in a northern plains tribal community
A large number of AI children received dental treatment under GA; many did so multiple times. Given the high cost of this treatment, even modestly effective preventive strategies such as silver diamine fluoride could yield cost savings
Survival analysis of caries incidence in African‐American school‐aged children
There was a global/overall significant caries protective effect of water consumption during the school-age period of child development
Longitudinal associations between dental caries increment and risk factors in late childhood and adolescence
With the exception of brushing frequency, modifiable risk factors under study were not significantly associated with ADJCI. When possible, researchers should consider presenting multiple models if fit criteria cannot discern among a group of optimal models
Associations of fluoride intake with children's cortical bone mineral and strength measures at age 11
In this cohort of 11-year-old children, mostly living in optimally fluoridated areas, life-long fluoride intakes from combined sources were weakly associated with tibia and radius cortical pQCT measures
AIC identifies optimal representation of longitudinal dietary variables
The method presented here can be used by researchers performing statistical modeling in dental research. This method provides an alternative approach for assessing the propriety of variable representation to significance-based procedures, which could potentially lead to improved research in the dental community
The relationships between fluoride intake levels and fluorosis of late‐erupting permanent teeth
Our results clearly show that dental fluorosis prevalence is closely related to fluoride intake levels and that teeth have greater susceptibility to fluoride intake during certain age intervals
A novel staging system for caries severity in the primary dentition
Our new metric is useful for quantifying disease burden from caries for high-risk children
Timing of primary tooth emergence among U.S. racial and ethnic groups
Tooth emergence occurs at a younger age for AI children than it does for contemporary White or Black children in the United States
Examination criteria and calibration procedures for prevention trials of the E arly C hildhood C aries C ollaborating C enters
An experienced multidisciplinary and multi-institutional team was able to develop criteria and training materials to anticipate situations and field conditions the main trials would encounter. Examiners were successfully trained and (re)calibrated
The willingness of US pediatric dentists to use atraumatic restorative treatment ( ART ) with their patients: A conjoint analysis
Although insurance coverage was the least important among the factors, being without insurance, being very young, and being uncooperative was the scenario where pediatric dentists most favored ART when making trade offs between different factors using the conjoint design
Prevalence and incidence of early childhood caries among A frican‐ A merican children in A labama
The majority of children developed caries during the 3-year follow-up, which is much higher than the 32 percent prevalence of caries among African-American children under age 6 years in National Health and Nutrition Examination Survey from 1999 to 2002
Patterns of complementary and alternative medicine ( CAM ) use among dental patients
A large proportion of dental patients reported use of CAM therapies. While CAM therapies and those who use them are diverse, given their widespread use, they clearly have potential impacts on the oral health of the public. Knowledge of the characteristics of dental patients who use CAM therapies is a first step in developing a broader understanding how CAM therapies and associated beliefs may affect oral health and public health programs
Factors associated with surface‐level caries incidence in children aged 9 to 13: The I owa Fluoride Study
D2+ F incidence on first molar occlusal surfaces in these young adolescents was associated with prior caries experience on other teeth as well as prior evidence of a D1 lesion on the occlusal surface. More frequent tooth brushing was protective of sound surfaces, and fluoride in home tap water was also protective, but significantly more so for adolescents in low-income families
Examiner reliability of fluorosis scoring: A comparison of photographic and clinical examination findings
Results suggest that interexaminer reliability is greater and fluorosis scores are higher when using photographic compared with clinical examinations
Dental caries in a cohort of very young American Indian children
Objectives: This paper reports the prevalence and severity of caries in a group of 16‐month‐old American Indian children. Methods: The study is an ongoing longitudinal study of risk factors for caries in children from a Northern Plains Tribal community. Children were examined for caries and risk factor data collected at approximately 1, 4, 8, 12, and 16 months of age. Surface‐specific caries data were collected and the presence of precavitated “w…
Factors associated with mutans streptococci among young WIC‐enrolled children
The presence of MS was associated with greater caries and plaque scores and with low maternal education and nonwhite racial background
The associations between dietary intakes from 36 to 60 months of age and primary dentition non‐cavitated caries and cavitated caries
The results suggest that different food and beverage categories are associated with being in the d1 group compared with the cavitated caries groups. More frequent toothbrushing, greater milk consumption at meals, and avoiding presweetened cereal consumption at meals might reduce the risk of developing non-cavitated caries
Engaging whiteness: How racial power gets reified in education
The central question addressed in this essay is how students engage in a class that focuses on the political and social power of whiteness. Specifically, it looks at how whiteness gets inscribed and reified in our education practices, even as we try to disrupt its normative influence. The essay is based upon an in-depth qualitative study of a graduate seminar dedicated to addressing diversity issues critically. We conclude that despite students' …
War and the Cultural Heritage of Iraq: A sadly mismanaged affair
The irony of the invasion and occupation of Iraq is that nations that believe they represent the acme of human progress have, by their own ignorance and incompetence, wreaked havoc in one of the oldest lands of human civilisation in response to a perceived threat that simply did not exist. With all the current rhetoric that the imposition of a Western model of reconstruction upon Iraq implies, it is useful to remind ourselves that Iraq has a cult…
Staging Stain Upon the Snow: Performance as a critical enfleshment of whiteness
Scholars in the emerging field of critical white studies maintain that as a result of the naturalization of whiteness, the vast majority of whites are blind to the power and privilege afforded by whiteness. This essay reflects on a production that attempted to put the spotlight on whiteness. Written from the points of view of the director and a performer, this essay reflects on the process of using reiterative stagings of Nathaniel Hawthorne's "T…
Foreign and domestic news content of Chinese television
A sample from 10 weeks of the major Chinese national television news program was content analyzed; 559 news stories were coded according to duration, topic category, position in the newscast, and geographic origin. The 189 international stories clustered at the end of the broadcast and were significantly shorter than domestic stories. A plurality of domestic stories was from the capital, Beijing, and covered different topics than those that origi…
Racial and Ethnic Disparities in Utilization of Dental Services Among Children in Iowa: The Latino Experience
Objectives. We sought to understand the role of Latino acculturation in dental care utilization in Iowa children. Methods. We used logistic regression to evaluate factors associated with having a previous-year dental check-up with 2005 Iowa Child and Family Household Health Survey data. We constructed models to examine the association with race/ethnicity and used chosen interview language to measure Latino acculturation. Results. After we control…
Greater and Lesser Gorhic Roofs: A Study of the Crown-Post Roof and its Antecedents
Previous investigations point to France as the original source of crown-post construction. Structural behaviour of vaults under Romanesque roofs reveals the logic of the central post. The Gothic roof of northern Europe is defined and its impact upon England is illustrated, leading to conclusions which reinforce earlier deductions

Creswell's Use of the Theory of Dating by the Acuteness of the Pointed Arches in Early Muslim Architecture
Historians evolve theories to explain patterns of behavior. Eventually these theories become tools which are used to probe and to expand inquiry and elucidate phenomena. Such a tool well developed by nineteenthcentury historians of the medieval period was the theory that buildings could be dated by the shape of their arching. Creswell's contribution to this theory was to apply it to early Islamic architecture and, by its use, to derive or substan…

Austria in the Thirties: Culture and Politics
Patterns of Dietary Fluoride Supplement Use During Infancy
Group average use of fluoride supplements was fairly consistent over the 12 months; however, individual patterns varied substantially. Estimated actual mean daily fluoride intake when including days that supplements were not received was substantially less than the recommended 0.25 mg per day
A Pilot Study of Dental Students' Esthetic Perceptions of Computer‐generated Mild Dental Fluorosis Compared to Other Conditions
This approach allows fluorosis to be better compared with other oral conditions because the images are standardized. Additional research with this method is warranted, including more variations in conditions, more comparisons, and other study populations
Factors Related to Decisions to Extract or Retain At‐risk Teeth
For teeth at risk for extraction, cost, substantial periodontal disease, and several clinical factors were predictive of extraction
A Comparison of Sealant Placement Techniques and 12‐month Retention Rates
Although more research is needed to improve air-abrasion applications, it does not appear that air abrasion without acid etching offers a significant advantage over traditional sealant placement methods and, in fact, appears to be inferior to the acid-etch technique for use in public health settings
Patterns of Fluoride Intake from Birth to 36 Months
There is considerable variation in fluoride intake across ages and among individuals. Longitudinal studies may be necessary to fully understand the relationships between fluoride ingestion over time and development of fluorosis
Prevalence of Dental Fluorosis in the Primary Dentition
The results of this study show that primary tooth fluorosis is relatively uncommon, but is most frequently seen on the posterior teeth, particularly the primary second molars, which form at later stages of development. This finding suggests that primary tooth fluorosis is mostly a postnatal phenomenon, and is associated with higher water fluoride levels

Dental Caries in the Primary Dentition: Assessing Prevalence of Cavitated and Noncavitated Lesions
Despite some concern with reliability of diagnosing d1 lesions, it appears that the d1d2-3 criteria are informative and useful in assessing the primary dentition
Patterns of Fluoride Intake from 36 to 72 Months of Age
Daily mean fluoride intakes from single and combined sources are relatively stable from 36-72 months of age among these children

From Perinet to Jelinek: Viennese Theater in Its Political and Intellectual Context
In twenty essays, prefaced by a historical introduction, this volume surveys key features of the last two hundred years of theatre in what was the principal theatrical centre of central Europe until the First World War, relating key playwrights, plays, and institutional developments to the political and intellectual context that has helped shape them. The studies combine to give a picture of conservative and progressive movements in Viennese thea…
The Association Between Environmental Tobacco Smoke and Primary Tooth Caries
Environmental tobacco smoke was associated with an increased risk of caries among children
Seasonal Variation in Fluoride Intake: The Iowa Fluoride Study
Fluoride intake from beverages for children aged 12-72 months is slightly higher in the summer and increases with mean monthly temperature. Fluoride intake from supplements and dentifrice did not change significantly with either season or temperature
Primary Tooth Fluorosis and Amoxicillin Use During Infancy
Fluoride exposure was the sole predictor of primary tooth fluorosis in a multivariate model. However, bivariate results suggest that amoxicillin could play a contributing role in the development of primary tooth fluorosis, especially for children exposed to lower levels of fluoride. An investigation of the relationship between amoxicillin intake and fluorosis of permanent teeth is warranted
Patterns of Dietary Fluoride Supplement Use in Children from Birth to 96 Months of Age
Objective: This paper reports on fluoride supplement use from birth to age 96 months. Methods: As part of the Iowa Fluoride Study, questionnaires were mailed at 3 to 6– month intervals assessing use of supplements. Estimated fluoride intake from supplements was calculated as a daily fluoride intake in mg. Analyses include descriptive statistics of supplements use for individual periods, area-under-the-curve (AUC) for combined periods, and associa…
The Roles of Meal, Snack, and Daily Total Food and Beverage Exposures on Caries Experience in Young Children
Dietary methods used to investigate diet-caries relationships can influence the outcome. The cariogenicity of food, but not beverages, is associated with the timing of exposure
