Materials and Method: Stone casts were poured from irreversible hydrocolloid impressions of 100 adult Egyptian participants. These casts were used to measure the maximum mesiodistal width, maximum crown length and the width/length ratio for each maxillary anterior tooth. In addition, two frontal photographs were taken for each participant and the visible anterior teeth width, length and width/length ratio were measured. Finally, a sample with gummy smile was selected and the gingival display of the original image was digitally manipulated to create a series of five images with different gingival displays, then these images were subjected to assessment by 50 dentists and 50 laypersons using a numerical rating scale. Results: There was statistically significant difference between female and male group for all teeth width values and W/L ratio of lateral incisor and canine. There was no significant difference between dentists and laypersons perception except for the smile with -4 mm gingival display. Conclusion: Gender affects actual teeth width values as well as actual and apparent W/L ratios of lateral incisor and canine. Laypersons considered 0mm and -2mm gingival display the most attractive situation, on the other hand dentists considered 0 mm gingival display the most attractive one, while all participants agreed that 4mm gingival display is the least attractive one.}, keywords = {width-length ratio,teeth dimensions,gingival display,dental esthetics,SMILE}, url = {https://adjc.journals.ekb.eg/article_30094.html}, eprint = {https://adjc.journals.ekb.eg/article_30094_09a85a9dc5a3a3b8a070da478e4c7be9.pdf} } @article { author = {kamal, kamal and mohamed, mohamed and Alazazi, Magdi and AbdoAlwahab, Amr}, title = {Immunohistochemical differentiation of proliferative activity in Warthin's tumor & different types of adenoid cystic carcinoma (p53, PCNA & CD34)}, journal = {Advanced Dental Journal}, volume = {1}, number = {1}, pages = {11-20}, year = {2019}, publisher = {Cairo University, Faculty of Dentistry}, issn = {2636-302X}, eissn = {2636-3038}, doi = {10.21608/adjc.2019.6936.1006}, abstract = {Aim: To study the expression of p53, PCNA & CD34 and differentiate the proliferative activity and angiogenesis of Warthin’s tumor & different types of adenoid cystic carcinoma. Methods: Hematoxylin and Eosin (H&E) and immunohistochemical staining techniques were used to detect p53, PCNA & CD34 proteins in 20 cases of Warthin's tumor & different types of adenoid cystic carcinoma (solid, tubular & cribriform pattern). Evaluation of immunostaining was done using computer image analyzer system & all data were statistically analyzed. Results: There was a statistically significant difference (P<0.05) in means of expression of p53, PCNA & CD34 between Warthin's tumor & different types of adenoid cystic carcinoma. Conclusion: The expression of p53, PCNA & CD34 have been associated with aggressive tumor progression and thus has been implicated as a predictive and prognostic marker and could provide useful prognostic markers for proliferative activity and good prognostic indicators for recurrence rate of adenoid cystic carcinoma.}, keywords = {p53,PCNA,CD34,salivary gland}, url = {https://adjc.journals.ekb.eg/article_30108.html}, eprint = {https://adjc.journals.ekb.eg/article_30108_28b472e835b5907fe9dae541899d2b8e.pdf} } @article { author = {zain, mohamed and hakam, maha and Abo el fotouh, Adel}, title = {Validity of Peek Patient Specific Implant (PSI) Containing Autogenous Bone Graft For Maxillary Reconstruction Following Lesion Enucleation - A Pilot study}, journal = {Advanced Dental Journal}, volume = {1}, number = {1}, pages = {21-26}, year = {2019}, publisher = {Cairo University, Faculty of Dentistry}, issn = {2636-302X}, eissn = {2636-3038}, doi = {10.21608/adjc.2019.7710.1010}, abstract = {Aim: The aim of this study is to evaluate the clinical and radiographic outcomes of PEEK/ PSI containing autogenous bone graft after enucleation of unilateral maxillary lesion encroaching maxillary sinus. Subjects and Methods: This study was conducted on ten patients (4 males and 6 females) with unilateral maxillary cysts encroaching the maxillary sinus. The age of the patients ranged from 15 to 59 with a mean of 33.1 years. All cases underwent surgical enucleation followed by immediate grafting with autogenous bone/xenograft mix in a PEEK /PSI to reconstruct the alveolar process and the maxillary sinus floor. Results: the results of this study demonstrated that pain intensity score according to the Visual Analogue Scale for the ten patients revealed: a minimum of 6 and a maximum of 10 with a mean of 7.2 preoperatively and a minimum of 0 and a maximum of 4 with a mean value of 1.8 one week postoperatively. According to radiographic results, Case number 5 was excluded from the statistical analysis of the radiographic results, as the PSI and the graft were removed 1 month postoperatively. Immediate postoperative bone density for 9 patients revealed: a minimum of 203.81 HU and a maximum of 413.79 HU with a mean of 318.79 HU. 4 months postoperative bone density for 9 patients revealed: a minimum of 274.75 HU and a maximum of 487.14 HU with a mean of 369.43 HU. Conclusion:The statistical analysis of the bone density immediately and 4 months postoperatively is considered to be very statistically significant.}, keywords = {PEEK,PSI,autogenous bone graft,maxillary reconstruction,lesion enucleation}, url = {https://adjc.journals.ekb.eg/article_30109.html}, eprint = {https://adjc.journals.ekb.eg/article_30109_805723cd48c6286bdc8afece1e8b1ceb.pdf} } @article { author = {Ali, Hesham and galal, manar}, title = {Management of Anterior Young Permanent Teeth with Apical Periodontitis by Apexification: A Case Report}, journal = {Advanced Dental Journal}, volume = {1}, number = {1}, pages = {27-30}, year = {2019}, publisher = {Cairo University, Faculty of Dentistry}, issn = {2636-302X}, eissn = {2636-3038}, doi = {10.21608/adjc.2019.7042.1009}, abstract = {Aim: The purpose of this study is to describe the treatment of immature permanent incisors with apical periodontitis, based on the placement of an apical mineral trioxide aggregate (MTA) plug for apexification.  Materials and Methods: A 9 years old boy was referred to the restorative and dental material department at National Research Center in Egypt, with a chief complaint of recurrent abscess and pain associated with the fractured central incisors. The first visit was accomplished by using Sodium Hypochloride (NaOCL) irrigation and intra-canal medication with tri-antibiotic paste (TAP) without instrumentation. Follow-up was done up to 18 months using standardized digital radiographs Results: After 6 month, the patient was asymptomatic and the radiographic examination showed rounding of root ending and peri-apical tissue repair. Conclusion:  It was concluded that use of MTA as an apical plug in necrotized teeth with open apices is a valuable option and may replace long-term apexification, thus reducing the treatment time with regard to the healing of the periapical lesions and the apical closure.}, keywords = {Mineral trioxide aggregate (MTA),Apexification,Permanent immature tooth and tri-antibiotic paste (TAP)}, url = {https://adjc.journals.ekb.eg/article_30110.html}, eprint = {https://adjc.journals.ekb.eg/article_30110_b07d0a17d671d97cd0288fc9bfe1403b.pdf} }
