“…[16] The common oral premalignant lesions were understood regarding their grading (leukoplakia) and underlying vascular patterns (lichen planus) by suing this method. [17,18] FA gave a negative correlation with maturation of midpalatal suture, serving as postsurgical quantitative prognostic marker. [19] Thus, the method was adopted considered to have diagnostic implications and used in the context of dental imaging.…”

Aim: Aim of the study was to evaluate the difference in bone trabecular pattern in terms of fractal dimensions (FD), in edentulous and dentulous areas on contralateral sides of the same patient's radiograph. Methodology: A retrospective study using box counting method of fractal analysis was performed on pre-processed 97 digital orthopantomographs (OPGs), after subjecting to inclusion and exclusion criteria with the fractal three software. Results: The mean FD of dentulous and edentulous regions was 1.812 ± 0.085 and 1.728±0.105 (P < 0.005), respectively, calculated by paired sample tests. Higher age group (Group 3) had lower FD values than other two groups (P > 0.01). Female sex had lower FD values than males (P > 0.01). Conclusion: The tooth loss (edentulous state) is associated with low FD, compared to tooth bearing areas. The method can be used to as a quick tool, to evaluate and compare the bone quality when prosthetic treatments are to be planned.

“…Many studies have been carried out, trying to find quantifiable signs that could help us to evaluate the malignant capacity of OLs. FD has been the subject of many of these studies, applying such values to the study of pathological anatomy samples, as well as to photographs of the clinical lesion itself [ 31 , 32 , 33 ].…”

Background: Oral leukoplakia (OL) is considered one of the most common potentially malignant oral disorders (OPMD), with a verified increased risk of developing oral cancer. The identification of the dysplasia grade (low–high) is the only consolidated factor used to evaluate this risk. The objective of this study was to verify the role of the fractal dimension (FD) in assessing this dysplasia. Methods: To begin, 29 OL and 10 normal oral mucosa (NOM) biopsies were retrieved for FD analysis of the epithelial (dime) and the connective (dimc) tissue. Results: In the OL group, the median value of dime is higher (1.67, IQR = 0.12) than for the NOM group (1.56, IQR = 0.08), with statistically significant differences (Wilcoxon test, p = 0.0031). There were no differences in relation to dimc. Significant differences were observed between the non-dysplasia vs. high-grade (p = 0.0156) and low-grade vs. high-grade (p = 0.0049) groups. No significant differences were identified in relation to dimc for the different degrees of dysplasia. For a cut-off point of 1.44 of dime, a specificity of 96.6% was obtained, a sensitivity of 100%, and an AUC = 0.819 (p = 0.003). Conclusions: FD at the level of the epithelium may be used as a diagnostic tool in OL.

Introduction: Complex geometric structures can be quantified by fractal analysis by generating a fractal dimension (FD), thus it can also measure the complexity of mucosa such as oral leukoplakia and other potentially malignant disorders. Aim: The study was done to perform the fractal analysis (FA) of oral mucosa in Oral leukoplakia, and to calculate its fractal dimension. Materials and Methods: 10 patients with clinically and histopathologically confirmed oral leukoplakia are analyzed through FA using box counting method in both pre treated and post treated cases. Results: The present study shows difference between fractal dimension in pre treated and post Short Research Article
