  • Full-Mouth Reconstruction in Amelogenesis Imperfecta: A Case Report
    Amin A. Marghalani
    American Journal of Case Reports, 2026
    BACKGROUND Amelogenesis imperfecta is a rare condition with a genetic predisposition that impacts enamel production, mineralization, or maturation. This condition impacts the affected individual's dental aesthetics, functionality, and emotional health. A multidisciplinary approach is recommended for effective management and a positive prognosis for dental treatment. CASE REPORT This case involves a 27-year-old woman diagnosed with amelogenesis imperfecta, characterized by extensive enamel defects, carious lesions, partial tooth loss, and significant aesthetic issues. The patient expressed dissatisfaction with the yellowish hue, uneven morphology, and small dimensions of her teeth. A comprehensive assessment revealed extensive enamel pitting, exposed dentin on several teeth, faulty dental restorations, multiple interdental gaps, misaligned teeth, and a class II malocclusion with a disparity between centric relation and maximum intercuspation. A staged, multidisciplinary treatment strategy was implemented, beginning with preliminary periodontal therapy and risk management, followed by surgical crown lengthening and the extraction of impacted or retained teeth. The final phase consisted of restorative rehabilitation, including posterior porcelain-fused-to-metal crowns, anterior lithium disilicate crowns, and fixed partial dentures. This treatment protocol successfully addressed the patient's aesthetic, phonetic, and functional needs. CONCLUSIONS This case highlights the complex management of amelogenesis imperfecta and underscores the critical need for individualized, interdisciplinary therapeutic approaches. A comprehensive literature review supports preventive interventions in childhood, adhesive and interim restorations in adolescence, and full-coverage prostheses in adulthood as the main components of effective management. When combined with patient motivation and a systematic recall schedule, favorable long-term prognoses can be achieved.

    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.

    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.

    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.

    Introduction: Periodontal disease is the most prevalent oral condition worldwide, resulting from a prolonged inflammatory reaction triggered by the buildup of dental plaque. Many studies have concluded that there is a strong association between periodontal health and tooth restorations, as the periodontium must be healthy for the restoration to last. Aim: to evaluate the impact of fixed and removable dental prostheses on the periodontal health of abutment teeth. Methodology: -prospective cohort study of 112 abutment teeth collected from 34 patients who received a total of 47 fixed (81 abutments) and 14 removable (31 abutments) dental prostheses treated by senior dental students under supervision during the past two years. Patients were recalled for clinical and radiographic examinations to assess periodontal parameters of abutments, including pocket depth (PD), clinical attachment loss (CAL), presence of plaque, and bleeding on probing (BOP), and to evaluate fixed and removable prostheses. Results: Most of the prostheses were fixed (72.32 %), and most of them were bridges (60.71 %) located in the anterior region of the mouth (58.56 %). The study findings showed a significant increase (mean = 0.46 mm) in clinical attachment loss after prosthesis placement (p < 0.01), while no significant difference was observed in pocket depth (p = 0.062). Furthermore, there was a significant increase in plaque at the follow-up visit compared to the baseline visit (p < 0.01) for only the fixed dental prostheses. There was no significant difference between fixed and removable prostheses regarding their impact on the periodontal health of abutments. Conclusion: The study found that abutment teeth had increased clinical attachment loss after receiving dental prostheses, highlighting the need for regular maintenance and patient education to maintain periodontal health.

    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.
