The usefulness of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) (J. was examined for 162 delinquent boys in a state training school. Their base rates, patterns, and configurations on all the MMPI-A scales and subscales were determined and compared with those of the 805 nondeliquent male adolescents in the MMPI-A standardization sample and with the original MMPI patterns of 7,783 delinquents identified in a literature review. The most prominent clinical scales were 4, 6, and 9, and 49/94 was the most frequent 2-point code.The study confirmed 14 of 18 hypotheses for mean differences on the 38 MMPI-A validity, clinical, supplementary, and content scales, and also found significant mean differences on 33 of the other 51 MMPI-A scales and subscalcs, 13 of which were large enough to be clinically meaningful. Most of the MMPI-A patterns and configurations were consistent with the literature on male juvenile delinquents.The original Minnesota Multiphasic Personality Inventory (MMPI) (Hathaway & McKinley, 1943) has been used in the clinical assessment of juvenile delinquents for over 50 years.Comparing 101 delinquent with 85 nondelinquent girls. Capwell (1945) reported that the delinquents had significantly higher scores on

Purpose Removal of ceramic restorations and appliances can be time consuming, invasive, and inconvenient. Erbium lasers offer an alternative noninvasive method for debonding of ceramic appliances. This paper aims to provide a comprehensive review of current literature on the effectiveness of erbium lasers for removal of ceramic restorations and appliances from natural teeth and dental implants. Methods A comprehensive search of 7 databases, including Medline (Ovid), Embase, Dentistry and Oral Sciences Source (DOSS), Web of Science, Cochrane Library, and ProQuest Dissertations and Theses was performed. The inclusion and exclusion criteria were agreed prior to the literature search. Two reviewers independently screened the title and abstract. A third reviewer then broke the tie, if any. The selected articles then underwent full text review and the data was extracted. Results The search identified 4117 unique articles published through June 10, 2021. Studies were assessed and categorized based on the type of restoration/appliance, type of abutment, type of laser, laser settings, efficacy of debonding, and pulpal temperature rise. Thirty‐eight full‐text articles were reviewed for inclusion. Time for ceramic debonding varies depending on the type of restorations and materials. Removal of zirconia crowns from teeth and implant abutments requires a longer period of time compared to lithium disilicate crowns. Temperature increases were reported as 5.5 degrees or less. Laser setting and laser type affect the debonding time and the increase in temperature. Examinations of debonded ceramics demonstrated no known structural damages resulting from laser applications. Conclusions Erbium lasers are effective noninvasive tools to remove all ceramic restorations/appliances from natural teeth and implant abutments without causing harm to abutments. Laser‐assisted debonding should be considered as a viable alternative to rotary instrumentation for ceramic crowns; however, clinical studies of erbium‐assisted ceramic retrieval are needed.

Background Coined by Westreich and Greenland in 2013, Table 2 fallacy refers to the practice of reporting estimates of the primary exposure and adjustment covariates derived from a single model on the same table. This study seeks to describe the extent to which Table 2 fallacy is present in the oral health literature and provide recommendations on presenting findings from multivariable‐adjusted models and/or interpretation of adjustment covariate estimates that are not the primary exposure. Methods We conducted a scoping review in PubMed and Scopus of human observational studies published in 4 oral health journals (JDR‐CTR, CDOE, JPHD, BMC Oral Health) starting in 2013 until the end of 2018. The resulting articles were exported into Excel and were either included or excluded for full‐text review based on six criteria. After categorizing the articles, we exported and summarized the results in SAS. Results A total of 1358 articles were initially screened of which 937 articles were excluded based on title or abstract for being animal studies, systematic reviews or meta‐analysis, prediction models or descriptive studies. The remaining 421 articles were eligible for full text reviewed of which, 189 (45%) committed Table 2 fallacy. The prevalence of table 2 fallacy appears high in the oral health literature. Conclusions The problem of presenting multiple effect estimates derived from a single model in the same table is that it inadvertently encourages the reader to interpret all estimates the same way, often as total effects. Implications and recommendations are discussed.
