Tooth Color as a Predictor of Oral Health‐Related Quality of Life in Young Adults

PURPOSE: Smiling plays an important role in social interaction. The purpose of this research was to explore the extent to which objective parameters of color of one's own teeth affected the social and emotional dimensions of young adults' lives. MATERIALS AND METHODS: The sample included 134 subjects- students of the University of Rijeka, Croatia (65% female) aged 19 to 28 years (median 21). All subjects had six intact maxillary anterior teeth without restorations or severe malocclusions and healthy gingiva with no signs of inflammation. Tooth color was assessed intraorally using a spectrophotometer. Lightness, chroma, and translucency of the right maxillary central incisors (the reference teeth) were calculated and used for analysis. Subjects reported dimensions of their oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP), Orofacial Esthetic Scale (OES), and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Linear relationships between elements of tooth color and OHRQoL were explored using Pearson correlations. Multiple linear regression, while controlling for the influence of age and gender, was also calculated. ANOVA with a Tukey post hoc test was employed to test whether nonlinear relationships existed between OHRQoL and categories of color elements. RESULTS: Dental self-confidence, esthetic concerns, orofacial appearance, social impact and psychological impact were not related to lightness, chroma, or translucency of the subjects' teeth. Neither linear nor nonlinear relationships were detected between those aspects. Satisfaction with smile esthetics was only related to translucency where subjects with moderate translucency were least likely to be satisfied (p = 0.033). Women tended to report greater psychosocial impacts than men (p < 0.05), regardless of their tooth color. CONCLUSION: According to the results of this study objective, measurable, quantitative parameters of tooth color did not accurately predict psychosocial dimensions of OHRQoL in dentate young adults

Green criminology and crimes of the economy: theory, research and praxis

This paper describes several key developments and dimensions in the field of ‘green criminology’ and discusses some of the relevant debates and controversies arising. It then outlines overlaps and connections with other areas of work within critical criminology. The central focus of the paper is on crimes of the economy as they affect the environment and a substantive, illustrative case study is provided on environmental crimes and harms associated with the oil industry. The paper concludes with some critical observations on where directions in theory, policy and practice may need to turn in a post-growth world
