The most important and difficult part of restorative dentistry is matching the teeth to their natural shade. The wrong colors have ruined many restorations. The goal at this stage is to create visually acceptable restorations and match the patient's existing dentition as closely as possible. The aim of the study was to determine the awareness of Saudi dentists towards the factors associated with failure in shade selection. The online questionnaire was constructed consisting of questions related to demographic data followed by questions including factors associated with failure in shade selection. Collected data were analyzed using SPSS version 22, where descriptive as well as inferential statistics were conducted. This study revealed that 60.4% of the dentists replied that patients consider changing the restoration when shading changes and the effect of knowledge of pigment colors 79% of the dentists admitted. The results conclude that 89% of the dentists accepted that knowledge of primary, secondary, and complementary colors is essential. More research showed that specialists had a deeper understanding of the factors behind tooth color selection compared to dental students, interns, and general dentists.

Background: Oral health knowledge is essential for establishing healthy behaviors. Aim: The purpose of the study was to determine and compare the basic oral health knowledge of 3-6th grade government primary school students and teachers in rural areas of Saudi Arabia. Methods: A cross-sectional study was conducted among government primary school students and teachers in a rural area (Thadig and Ad-Delam) of the Riyadh region of Saudi Arabia using validated, structured, close-ended and self-administered questionnaires. The questionnaire comprised demographic variables and 18 multiple-choice items. A convenience sampling methodology was employed to select the study sample. Results: A total of 1864 subjects from rural area government primary schools [students (N = 1538) and teachers (N = 326)] participated in this study. The majority of the students were females 841 (54.7%), Saudi nationals 1376 (89.5%), and studying in 5th grade 446 (29%). Most teacher participants were females, 199 (61.0%), and Saudi nationals, 326 (100.0%). Teachers (12.62 ± 2.36) demonstrated significantly higher overall mean knowledge scores compared to the students (9.63 ± 2.36) (p < 0.001). Females and non-Saudi students showed significantly higher mean knowledge scores compared to their counterparts. However, 4th standard students showed significantly lower mean knowledge scores compared to other graders. Female teachers (13.17 ± 2.25) demonstrated significantly higher overall oral health knowledge scores compared to male teachers (11.75 ± 2.26) (p < 0.001). Conclusion: Basic oral health knowledge was adequate among 3-6th grade government primary school students and teachers in rural areas of the Riyadh region.

Objective: This study aimed to assess and compare the knowledge and awareness of dental interns and general practitioners in Saudi Arabia about late mandibular incisor crowding. Materials and methods: This is a cross-sectional study which was conducted between June 2020 and July 2020 in Saudi Arabia and it observed dental practitioners. Results: A total of 275 subjects were included in this study; 172 (62.5%) were dental interns, 157 (57.1%) were females and 211 (76.7%) dentists were aged between 23-26 years. While most general practitioners and dental interns have heard about late mandibular incisors crowding, the majority continue to abstain from not recommending extraction of lower third molar as a means of prevention. Around half of the respondents, 134 (48.7%), claimed that the eruption of lower third molars is a possible causative factor. A greater percentage of general dental practitioners, 32 (31.1%) believed that there is a correlation between late mandibular incisors crowding and cases of relapse after an orthodontic treatment. Moreover, male participants were more knowledgeable of the fact that cases may worsen if not treated (P = 0.019). The knowledge of lower third molars eruption (P = 0.002) and unerupted/impacted lower third molars (P = 0.034) ability to cause late mandibular incisors crowding and the prophylactic extraction of the lower third molars (P = 0.009) were also significantly differed across the various age groups. Conclusion: Late mandibular incisor crowding is one of the main clinical issues in dental practice which has been subject to decreased awareness among dentists. Keywords:Dentists, knowledge, late mandibular incisor crowding, Saudi Arabia.

Traumatic dental injuries can significantly impact the appearance and the functions of the affected teeth and can induce significant damages to the surrounding structures within the oral cavity including both the soft and hard ones. This present literature review aimed to discuss the appropriate orthodontic management of dental traumatic events and to present evidence from previous studies in the literature. The search took place in the relevant databases l, such as PubMed, Web of Science, Scopus and Google Scholar to find the relevant articles that have previously discussed the topic to retrieve all the potentially related information that will help to formulate strong evidence. The literature review was focused on the orthodontic management considerations for patients that had dental traumas including crown and crown-root fractures, in addition to intrusion and extrusion luxation injuries. Overall, orthodontists should be able to deal with all the possible traumatic lesions as early as possible to avoid the development of any complications which might affect the prognosis of the affected teeth and the surrounding structures. Moreover, the evidence suggested that aforementioned lesions which was a period of at least three months should be recommended after applying the orthodontic treatment to early screen against any potential complications and maintain stabilization.
