An In-Vitro Assessment of Operator Accuracy and Inter-Operator Agreement in Recording Shade and Shade Characteristics.

Color assessment remains a challenging aspect of esthetic dentistry. This study aimed to evaluate inter-operator agreement and accuracy in assessing shade parameters and to investigate the effect of different clinical backgrounds of the operators under different lighting conditions. Three veneers with a single shade (VITA VM7, shade 2M2: VITA Zahnfabrik, Bad Säckingen) and different shade characteristics (lustre, translucency and opacity) were assessed by 24 operators with different backgrounds using natural and color-corrected light (Trueshade, Interempresas Media, S.L.U. - Grupo Nova Àgora, Spain). Shade assessment accuracy was only 5.5% using natural light and 9.7% using Trueshade. The majority of operators identified value and hue correctly, although chroma was mostly identified incorrectly. The most accurate assessments were recorded by technicians, and translucency was the characteristic to be least accurately recorded. Inter-operator agreement of shade was better with Trueshade compared without Trueshade, although group agreements of shade characteristics were higher without Trueshade for lustre and opacity, but not for translucency. Operators showed limited agreement and poor accuracy in assessing shade and shade characteristics and the clinical background had an effect on shade selection. Technicians were more reliable in shade assessment. Trueshade could be a promising tool to improve shade assessment outcomes.

Parental perception and acceptance of silver diamine fluoride treatment among Syrian refugees.

OBJECTIVE: Silver diamine fluoride (SDF) is an effective cariostatic agent, although staining associated with treatment is a significant impediment to its acceptability. BASIC RESEARCH DESIGN: A cross-sectional study of Syrian refugees to identify acceptance of SDF treatment. METHODS: Information was collected on: sociodemographics, medical/dental child history, dental status (dmft/DMFT), andperceptions of photographs of SDF-treated teeth. Associations between clinical findings and the acceptability were assessed. RESULTS: Of 258 parents or guardians, 37.8% accepted SDF treatment for their children. Acceptance was related to the location and type of teeth, being higher for primary than permanent teeth, and posterior than anterior teeth in both dentitions. Uncooperative behavior during previous dental treatment, the presence of dental discoloration, history of child dental pain, and number of filled teeth were all associated with better parental acceptance. Acceptance was also related to parental age, level of education, and their relation to the child. CONCLUSION: Parents' acceptance of SDF treatment is low. However, staining on posterior teeth was more acceptable than staining on anterior teeth and on primary more than permanent teeth.

Migrant and refugee Oral Health.

This issue contains two papers on the oral health of migrant people. The oral health of migrants, refugees, and asylum seekers is often worse than the general oral health of the host country's population (Crespo, 2019; Davidson et al., 2006). Poor oral health outcomes in migrants are due to a combination of upstream, psychosocial, and behavioral factors. Migrant communities might then have vital priorities that compete with oral health. Consequently, they may express lower needs and may not focus on oral health; all these factors lead to a higher risk of developing dental diseases. Lack of oral health services is commonly seen due to limited fi nancial resources or lack of dental providers in the vicinity of migrant communities or refugee camps. They face ad- ditional cultural and linguistic barriers in navigating the health care system of a new country.

Oral health status and risk determinants in adult Syrian refugees in Jordan.

OBJECTIVES: Lack of data regarding the oral health of Syrian refugees represents a crucial gap in the literature. This study aimed to investigate the oral health status of Syrian refugees and related socio and behavioral factors. BASIC RESEARCH DESIGN: Cross-sectional study from June to September 2019 at Zaatari refugee camp, Jordan. METHODS: An experienced, calibrated field investigator performed an oral clinical examination of 505 Syrian refugees (18-60 years) using the WHO criteria. DMFT, SiC, oral health indices and socio-demographic variables were recorded. RESULTS: A total of 264 males and 241 females were included. The prevalence of caries was 96.0%, of which 76.0% had 4-17 carious lesions. The mean number of decayed, missing and filled teeth was 5.76, 2.55 and 1.88 respectively. The mean DMFT score was 10.19 (100% had DMFT⟩0), SiC was 17.09, and the mean simplified Oral hygiene index score was 2.18. The most common chief complaint was pain (92.7%). Nearly half of the participants were smokers (45.7%). There was a negative association between level of education and oral health (P=0.011). Most participants did not brush their teeth regularly (87.5%). Females had better oral hygiene practices than males (P=0.015). CONCLUSIONS: Syrian refugees had a high prevalence of caries, high unmet dental treatment needs and poor oral hygiene practices. Preventive programs and focused interventions may reduce the burden of disease in this underprivileged population, on funding agencies and host countries as well.
