Three-dimensional facial modeling software was used to generate facial models, which were sculpted using three-dimensional model sculpting software to simulate different nasal base, zygomatic bone, and upper lip prominence conditions. A total of 15 facial models were generated, divided into five groups (three models per group): Group A (normal nasolabial angle, normal nasal base, normal upper lip); Group B (increased nasolabial angle, normal nasal base, flattened upper lip); Group C (decreased nasolabial angle, normal nasal base, protruded upper lip); Group D (increased nasolabial angle, protruded nasal base, normal upper lip); Group E (decreased nasolabial angle, recessed nasal base, normal upper lip). Models 1, 2, and 3 in each group had normal, protruded, and flattened zygomatic bones, respectively (with Model 1 in Group A as the initial model). Forty-five-degree and ninety-degree profile images of the models were captured (30 images in total) and compiled into a questionnaire. Participants in the three study groups were selected as the most attractive and least attractive facial appearances based on the questionnaire and ratings of the lip prominence of the 45° and 90° profile images (0-10 points, where 0=very flat, 5=normal, and 10=very prominent). A one-sample t-test was used to compare the difference between model ratings and the median score of 5. &lt;b&gt;Results:&lt;/b&gt; Among the 30 images, the proportion of lip prominence ratings deviating from the median score of 5 was the highest among orthodontists [83% (25/30)], followed by orthodontic patients [67% (20/30)], and lowest among healthy adults [53% (16/30)]. At the 90° profile view, the scores given by orthodontists, orthodontic patients, and healthy adults for the initial model (5.07±0.79, 5.00±1.03, and 4.95±1.07, respectively) showed no statistically significant difference from 5 (&lt;i&gt;t=&lt;/i&gt;0.65, &lt;i&gt;P=&lt;/i&gt;0.521; &lt;i&gt;t=&lt;/i&gt;0.00, &lt;i&gt;P=&lt;/i&gt;1.000; &lt;i&gt;t=&lt;/i&gt;-0.42, &lt;i&gt;P=&lt;/i&gt;0.673).

Then, they were screened and divided into 3 parts. One part of dentin specimens was subjected to bacterial biofilms to prepare artificial carious dentin (ACD). They were further ground by 600-grit SiC paper for 0, 12, 24, 36, and 48 s, respectively to obtain 5 groups with different layers of ACD: ACD-0, 12, 24, 36, and 48 s. Sound dentin was used as the control group. To determine the preparation parameter for artificial caries-affected dentin (ACAD), the first part of specimens was used for bacterial visualization observation (&lt;i&gt;n&lt;/i&gt;=3) and demineralization analysis experiments (micro-CT, Raman spectroscopy, and surface micro-hardness analyses, &lt;i&gt;n&lt;/i&gt;=3). Another part of dentin specimens was allocated to 3 groups: control group (sound dentin), artificial caries-infected dentin group (ACD-0 s) and ACAD group (prepared according to the parameter determined by the experiments above). They were used for color tests (&lt;i&gt;n&lt;/i&gt;=10), Raman spectroscopy analysis (&lt;i&gt;n&lt;/i&gt;=6) and scanning electron microscope (SEM) observation (&lt;i&gt;n&lt;/i&gt;=1), thus comparing color, chemical composition and structure, and micro-morphology of 3 groups. The rest of dentin specimens were divided into 2 groups: sound dentin and ACAD (&lt;i&gt;n&lt;/i&gt;=6), which were bonded to composite resin with Single Bond Universal in a self-etch mode. Then, the bonding interface was measured using an electron probe micro-analyzer (EPMA). &lt;b&gt;Results:&lt;/b&gt; The depth of bacterial invasion for ACD-0 s was (142.4±25.8) μm. And obvious bacteria were observed in the dentin tubules for the ACD-12 s group. For micro-CT, the demineralization depth was (283.9±25.6) μm for ACD-0 s and (139.2±27.9) μm for ACD-36 s. The grey values in some regions of the dentin surface for ACD-48 s resembled those of sound dentin. For Raman spectroscopy, the peak ratio of phosphate to amide Ⅰ was significantly lower for ACD-24 s [4.2 (3.2,6.7)] than ACD-36 s [6.7 (6.0,7.7)] (&lt;i&gt;P&lt;/i&gt;&lt;0.05).

However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The \"Healthy China Action (2019-2030)\" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the \"Expert consensus: reducing free-sugar for caries prevention\", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world.
