BackgroundOver one third of reproductive age women in the US are obese. Pregnancy is a strong risk factor for obesity, with excess weight gain as the greatest predictor of long term obesity. The majority of pregnant women gain more weight than recommended by the Institute of Medicine guidelines. The objective of this study was to understand prenatal care providers’ perspectives on weight gain during pregnancy.MethodsSemi-structured qualitative interviews of 10 prenatal care providers (three family physicians, three obstetricians, and four nurse midwives) at a University Hospital in the Midwest, that included the ranking of important prenatal issues, and open-ended questions addressing: 1) general perceptions; 2) approach with patients; and 3) clinical care challenges.ResultsProviders felt that appropriate weight gain during pregnancy was not a high priority. Many providers waited until patients had gained excess weight before addressing the issue, were not familiar with established guidelines, and lacked resources for patients. Providers also believed that their counseling had low impact on patients, avoided counseling due to sensitivity of the topic, and believed that patients were more influenced by other factors, such as their family, habits, and culture.ConclusionsBoth providers and patients may benefit from increased awareness of the morbidity of excess weight gain during pregnancy. Practice-level policies that support the monitoring and management of weight gain during pregnancy could also improve care. Research that further investigates the barriers to appropriate weight gain is warranted.

“…The major shades for the first age group were all found to have higher values in their respective hue groups, in accordance with Vitapan's classical shade guide, as opposed to the second and third age groups, which tended to have lower values for the major shades across the four hue groups. The most common shade values for this shade guide were discovered to be A1, A2, A3, B2, C1, D2, and D3 [ 13 , 18 , 19 ]. The current investigation also discovered secondary dentine deposition, which has been documented in the literature and results in teeth turning darker and more reddish with age.…”

BackgroundIt is essential for dentists and technicians to work together to fabricate and create restorations that are a "perfect" shade match for a particular person. Thus, the Vitapan 3D-Master tooth shade system (Vita Zahnfabrik, Germany) was created and put into use in order to improve the accuracy of shade-selection operations. The objective was to visually assess the color of the maxillary anterior teeth in male and female subjects from various age groups in Uttar Pradesh, India. Materials and methodsThere were 150 patients in total, and they were divided equally into three groups of 50: Group I, which included patients aged 18 to 30; Group II, which included patients aged 31 to 40; and Group III, which included patients aged 41 to 50. Ceiling-mounted fluorescent lighting fixtures with PHILIPS 65 D tubes (OSRAM GmbH, Germany) were installed. Three medical experts provided their opinions as part of this research. The maxillary central incisor was placed next to tabs of various shades, and the doctors' final assessment was based solely on the central one-third of the face. From each of the two sample sets, a total of 30 patients were selected. Once the crown had been made from the prepared tooth of the patient, it was colored according to two shade guidelines (Vita Classic and Vita 3D Master). The three clinicians matched the shade of the manufactured crown with visual shade guides. For shade matching, a modified United States Public Health Service (USPHS) standard was employed. ResultsThe Chi-square test was used to compare categorical variables across groups. According to the Vitapan Classic shade guide, 26% of Group I participants matched the first Hue group (A1), 14% of Group II participants matched the first Hue group (A3), and 20% of Group III participants matched the second Hue group (B2). Master shade guide for Vita 3D 26% of Group I participants matched with the second value group (2M2), 18% of Group II participants matched with the third value group (3L 1.5), and 24.5% of Group III participants matched with the third value group (3M2). Eighty percent of people who were matched to Alpha scored for crowns made using the Vita 3D Master shade guide, while 94.1% of people who were matched to Charlie scored for crowns made using the Vitapan Classic shade guide in a comparison of the two shade guides. ConclusionThe majority of the shades obtained from the Vita 3D master shade guide were found to be 1M1 and 2M1 in the younger patients, 2M1 and 2M2 in the second age group, and 3L 1.5, 3M2 in the older age group. In contrast, the Vitapan Classic shade guide revealed A1, A2, A3, B2, C1, D2, and D3 as the predominant shades.
