Alveolar Ridge Preservation with A Free Gingival Graft in the Anterior Maxilla: Volumetric Evaluation in A Randomized Clinical Trial
(2015) Karaca, C.; Er, N.; Gulsahi, A.; Koseoglu, O. T.; 25682463
The aim of this study was to evaluate and compare the dimensional changes in maxillary extraction sockets that have healed spontaneously and those treated with free gingival grafts. Ten subjects with at least two maxillary anterior teeth scheduled for extraction were selected for this study. Two maxillary teeth were allocated randomly to either the test group or the control group. In the test group, the extraction socket was covered with a free gingival graft harvested from the palate, while in the control group the sockets healed spontaneously. Cone beam computed tomography (CBCT) scans were taken on the day of extraction and at 3 months postoperative. Soft tissue healing of the extraction sockets was assessed visually by clinical inspection. Hard tissue measurements were obtained from the CBCT scans. After 3 months of healing, the control sockets had lost height in the buccal and lingual crestal bones (-1.03 and 0.56 mm, respectively); however, the height in the buccal and lingual crestal bones was preserved at the test sites (+0.06 and +0.25 mm, respectively). This difference between the two groups was statistically significant (P < 0.05). In contrast, both the control and test groups lost width in the buccal and lingual crestal bones; the difference between the control and test groups was not statistically significant (P > 0.05). The authors propose that covering the orifice of the extraction socket with a free gingival graft can result in preservation of the alveolar bone height.
Assessment of Intraoral Image Artifacts Related to Photostimulable Phosphor Plates in A Dentomaxillofacial Radiology Department
(2016) Gulsahi, A.; Secgin, C. K.; 26856290; GRR-7726-2022
Objective: The aim of the present study was to evaluate the presence, frequency, and causes of artifacts in intraoral images obtained using photostimulable phosphor (PSP) plates. Materials and Methods: A total of 11,443 intraoral images, including 4291 periapical and 7152 bitewing images, acquired over a 6-month period as well as over a month 1-year after the initial imaging were evaluated by a single observer and image artifacts only related to the PSP system were recorded. Before the study, an experienced dentomaxillofacial radiologist and a research assistant assessed a set of image artifacts and agreed on the causes of these artifacts. All unidentified artifacts were reassessed by both researchers before the final decision. The data were analyzed using the statistical software SPSS 11.5. Results: The total number of images with one or more artifacts was 2344 (20.4%). Of these, 2008 were of adult patients and 336 were of pediatric patients. While movement of the phosphor plate in the disposable pocket was the most common cause of the observed image artifacts in the children, non-uniform image brightness was the most frequently observed artifact in the case of the adults. Conclusion: The percentage of images with artifacts in the 6(th) month was lower than that during the 1(st) month. More significantly, the lowest percentage was obtained 1-year after the initial imaging, owing to the increase in familiarity with the system. Understanding the reasons for the image artifacts and studying ways of preventing are of high clinical importance.
Comparison Of The Third Molar Maturity Index (I-3M) Between Left And Right Lower Third Molars To Assess The Age Of Majority: A Multi-Ethnic Study Sample
(2021) Angelakopoulos, N.; Galic, I.; Kis, H.C.; Jimenez, L. Gomez; Zolotenkova, G.; Balla, S. B.; Yusof, M. Y. P. Mohd; Selmanagic, A. Hadzic; Pandey, H.; Pereira, C. Palmela; Nobrega, J. B. M.; Hettiarachchi, K.; Mieke, S. M.; Kumagai, A.; Gulsahi, A.; Zelic, K.; Marinkovic, N.; Kelmendi, J.; Bianchi, I.; Vazquez, I. Soriano; Spinas, E.; Velezmoro-Montes, Y.W.; Oliveira-Santos, I.; De Luca, Stefano; Ribeiro, I. L. Arrais; Moukarzel, M.; Cameriere, R.; 34228192
The diagnostic accuracy of the I-3M to assess the legal age of 18 years has already been tested in several specific-population samples. The left lower third molar has been extensively used for discriminating between minors and adults. This research aimed to compare the usefulness of lower third molar maturity indexes, from both left and right side (I3ML and I3MR), in samples originating from four distinct continents in order to examine possible differences in their accuracy values. For this purpose, a sample of 10,181 orthopantomograms (OPGs), from Europe, Africa, Asia and America, was analysed and previously scored in other studies. The samples included healthy subjects with no systemic disorders with both third molars and clear depicted root apices. Wilcoxon Signed Rank test for left and right asymmetry did not show any significant differences. Data about sensitivity, specificity, predictive values, likelihood ratio and accuracy were pooled together and showed similar results for I3ML and I3MR, respectively. In addition, all these quantities were high when only the I3MR was considered to discriminate between adults and minors. The present referable database was the first to pool third molar measurements using panoramic radiographs of subjects coming from different continents. The results highlighted that both I3ML and I3MR are reliable indicators for assessing the legal age of 18 years old in those jurisdictions where this legal threshold has been set as the age of majority.
The Reliability of Cameriere's Method in Turkish Children: A Preliminary Report
(2015) Gulsahi, A.; Tirali, R. Ebru; Cehreli, S. Burcak; De Luca, S.; Ferrante, L.; Cameriere, R.; 0000-0001-6487-3984; 25704458; AAD-2907-2020
Dental age estimation in children is an important issue both legally and medically. Currently, however, there is a lack of contemporary dental age estimation standards for a Turkish population. This study assessed the accuracy of Cameriere's method by examining the panoramic radiographs of 573 healthy Turkish children between the ages of 8 and 15 years. Radiographs of the left permanent developing mandibular teeth, except wisdom teeth, were evaluated. All subjects were divided into 7 groups according to their chronological age. The Intra-class Correlation Coefficient was used to determine the intra-and inter-observer agreement error. A comparison of the distributions of estimation errors among age groups was performed using the Nemenyi test. There were no significant differences between inter-observer (p = 0.352), and intra-observer readings after 2 weeks (p = 0.275 and p = 0.273, respectively). The dental age was underestimated when using Cameriere's method with a mean difference of -0.35 years (-0.24 years for girls and -0.47 years for boys). The median values of the differences between dental and chronological age were -0.44 years in boys (range: -3.70, 4.06) and -0.21 years in girls (range: -2.74, 3.29). In addition, the differences between dental and chronological ages in the different age groups decreased with increasing chronological age. Results from the Nemenyi test implied that Cameriere's method is more accurate for girls than for boys in this cohort of a Turkish population. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
