Radiographic characteristics of impacted teeth: A retrospective study of 2199 radiograph Amin A. Marghalani, Arwa U. Alsaggaf, Abdullah Hazzazi, Anmar Dahlawi, Mohd. B. Badaoud, et al. Plos One, 2025 Objective To analyze the radiological characteristics of impacted teeth in the population of Makkah in Saudi Arabia. Methods A retrospective analysis was conducted on 2199 digital panoramic radiograph (OPG) scans collected from the database of the dental teaching hospital at Umm Al-Qura University, Makkah, KSA. Out of these, 1503 OPGs (749 males and 754 females) met the inclusion criteria, which required clear OPGs with high quality and good visibility of anatomic structures. The study included patients of both genders, aged between 13 and 70, with complete root formation of impacted teeth. Results The analysis of 1,503 patients’ radiographs revealed that 27.70% had impacted third molars, with mandibular molars being more commonly affected than maxillary molars. Additionally, other impacted teeth were observed, including maxillary canines, second premolars, second molars, and supernumerary teeth. Male patients had a slightly higher prevalence of impaction. The majority of impacted third molars were found in the age group of 18-30. The angulation and depth of impacted teeth differed between maxillary and mandibular arches. Most impacted mandibular third molars had a class I relation with the ramus. Conclusion The study provides valuable insights into impacted teeth in Makkah, Saudi Arabia. It highlights a significant occurrence of impacted third molars, as well as other teeth. These findings contribute to a better understanding of impacted teeth and provide important support for dental professionals in their efforts to improve patient outcomes.
Assessment of Removable Partial Denture Design Skills among Undergraduate Dental Students: A Cross-sectional Study Sarah Nassief, Rayan Sharka, Amin Marghalani, Amira Faramawy, Haitham A. Elsisi, et al. Open Dentistry Journal, 2025 Background There is a growing need for skilled dentists who can offer high-quality treatment for patients who need sophisticated Removable Partial Dentures (RPDs). Therefore, it is essential for undergraduate training programs to ensure that students have the requisite skills and competencies to meet this demand. Aim: This study was conducted to assess the skills of undergraduate dental students in producing clinically effective RPD designs. Materials and Methods A clinical scenario for a patient who required RPD was created. Over the period of two consecutive academic years, from 2022 to 2024, fourth- and sixth-year undergraduate students were invited to participate in the study. The students were instructed to draw the most appropriate design for the case. An answer sheet was prepared to guide the evaluation of the students’ skills in designing RPD frameworks. Descriptive and inferential statistical analyses were computed to assess the distribution of the RPD design scores, and the statistical significance was set at 0.05. The Mann–Whitney U test was used to compare score differences between groups. Results A total of 197 undergraduate dental students participated in this study. The descriptive analysis of the RPD design components demonstrated that the majority of students received excellent or satisfactory scores for most RPD design components, with the exception of indirect retention, major connectors, and matching the drawing with writing, where students received ratings that needed improvement, which were 15%, 10%, and 7%, respectively. Female students received higher overall scores than male students, with a statistically significant difference between the two groups (p < 0.001). Moreover, fourth-year students significantly outperformed sixth-year students in their overall scores (p = 0.007). Conclusion The undergraduate students were found to have the knowledge and fundamental skills necessary to create basic, clinically effective RPDs. However, students need to study RPD design principles consistently throughout their clinical years. This can be accomplished using contemporary pedagogies for instruction on removable prosthodontics.
The Influence of Impacted Mandibular Third Molar in Health-related Quality of Life Omair M. Bukhari, Shahad L. Alhassani, Sumayyah L. Alkhudhayri, Mariam R. Alharbi, Reem J. Alahmadi, et al. Open Dentistry Journal, 2025 Background Quality of Life (QoL) is defined as “a person's view of their status in life, shaped by the cultural and value systems surrounding them, along with their goals, expectations, standards, and worries.” The literature lacks information supporting the effect of impacted third molars on Oral Health-Related Quality of Life (OHRQoL). Impacted third molars could affect the function of mastication, which consequently affects quality of life. Aim This study aimed to evaluate the impact of impacted third molars on oral health quality using the Oral Health Impact Profile (OHIP-5) questionnaire. Materials and Methods A cross-sectional study was conducted to investigate the effect of impacted third molars on Oral Health-Related Quality of Life (OHRQoL). The participants were interviewed using an Arabic version of the Oral Health Impact Profile with five items (OHIP-5). Results In 148 participants aged 19 to 70 years, the Oral Health Impact Profile (OHIP) score indicates that participants with impacted teeth had higher scores than the control group (no impaction), with a statistically significant p-value of less than 0.05. This confirms the effect of third molar impaction on quality of life. Conclusions Impacted third molars significantly affect OHRQoL due to pain, infections, functional and aesthetic issues, psychological stress, economic pressures, and accessibility to care. Examining these factors is crucial for developing strategies to mitigate their negative effects. Proper management can enhance the well-being and quality of life of those impacted.
Vertical Marginal Discrepancy of a Monolithic Zirconia Crown with Different Cement Spaces Turki Alkhallagi, Meshari Alzahrani, Majed Ali Alkathiri, Ghadeer I. Basunbul, Amin Marghalani International Journal of Dentistry, 2023 The long-term clinical success of indirect restorations highly depends on their marginal integrity. The cement space is an element that might affect the marginal integrity, but it can be altered during the configuring of the computer-assisted designing/computer-aided manufacturing (CAD–CAM) restoration. However, there is controversy in the literature regarding the effect of the cement space on the precision of zirconia crown marginal adaptation. The aim of this study was to measure the vertical marginal discrepancies between different cement thickness settings for CAD–CAM monolithic zirconia restorations. Material and Methods. An artificial mandibular right molar tooth mounted on a typodont was prepared for a zirconia crown using the standard method. The study sample consisted of 30 zirconia crowns (Zenostar Zr Translucent Zirconia, Weiland Dental, Germany) milled using an (iMes-iCore) milling machine. Each group of 10 crowns was designed with 30–50 and 70 μm spacer thicknesses. The vertical marginal adaptation at the center of the four different planes (mesial, distal, buccal, and palatal) was measured under a microscope at 40x magnification. A one-way analysis of variance test was used for statistical analysis. Results. The mean of Group 30 was 27.45; of Group 50 was 22.22; and of Group 70 was 22.90. There was no statistically significant difference between the groups ( p ≥ 0.5 ). Conclusions. The increase in the cement space up to 70 μm did not influence the vertical marginal adaptation of the monolithic zirconia crowns.
