I have been a full-time professor, coordinator of the Professional Master's Program in Radiology, and professor responsible for the Imaging I, II, and III courses at the São Leopoldo Mandic Faculty of Dentistry since 2010. I have experience in Dentistry, with an emphasis on Cone Beam Computed Tomography and Ultrasound, primarily in diagnostic imaging. I have developed two patents, one granted and one pending, and registered software.
EDUCATION
I hold a degree in Dentistry from the Pontifical Catholic University of Campinas (1996) and a doctorate in Dentistry (sub-area Radiology) from the São Leopoldo Mandic Center for Postgraduate Studies and Dental Research (2009). I have advanced training in Orofacial Doppler Ultrasound.
Facial Growth Patterns and Midpalatal Suture Maturation in Adults: A Retrospective CBCT-Based Observational Study Elizabety do Nascimento Silva, Nathalie Murielly Rolim de Abreu, Frederico Barbosa de Sousa, Francine Kuhl Panzarella, Rudyard dos Santos Oliveira Orthodontics and Craniofacial Research, 2026 Objective To investigate whether facial growth pattern is associated with the maturation stage of the midpalatal suture (MPS) in adults using cone‐beam computed tomography (CBCT). Materials and Methods This retrospective study reviewed 300 full‐skull CBCT scans acquired between January 2018 and May 2023, of which 120 met the eligibility criteria. Individuals aged 18 years or older were classified according to facial growth pattern (brachyfacial, mesofacial or dolichofacial) using Ricketts' VERT index. Age was categorised into < 30 and ≥ 30 years based on clinical evidence suggesting increased frequency of sutural fusion after the third decade of life. Exclusion criteria included craniofacial anomalies, syndromic conditions, systemic or hormonal disorders affecting skeletal growth, impacted teeth, previous maxillary surgery, trauma and inadequate image quality. MPS maturation was assessed using Angelieri's five‐stage classification (A–E). Two calibrated examiners independently evaluated all cephalometric and tomographic records. Ordinal multinomial logistic regression was applied to analyse associations between facial growth pattern, age, sex and MPS maturation stage. Results Facial growth pattern was significantly associated with MPS maturation stage (χ 2 = 20.65, p < 0.001), with dolichofacial individuals more frequently presenting earlier maturation stages (B or C). Age ( p = 0.297) and sex ( p = 0.870) were not significantly associated with MPS maturation in this adult sample. Reliability analysis demonstrated excellent intra‐ and inter‐examiner agreement (ICC = 0.95; κ = 0.98). Conclusion Facial growth pattern was associated with MPS maturation stage in adults and may function as an adjunctive diagnostic parameter. Dolichofacial individuals more frequently exhibited earlier stages of sutural maturation, whereas age and sex showed no significant association. Although facial pattern analysis should not replace CBCT evaluation, it may contribute to a more individualised, anatomy‐based diagnostic assessment. These findings should be interpreted cautiously due to the cross‐sectional design and specific population studied.
Postoperative Complications After Extraction of Impacted Mandibular Third Molars: A Clinical Observational Study On Dental Position And Risks Daniela Camila Nunes Miguel, Rudyard dos Santos Oliveira, Francine Kühl Panzarella Journal of International Society of Preventive and Community Dentistry, 2025 Aim: This study examined the associations between the position of impacted mandibular third molars and postoperative complications, with a focus on pain, swelling, and their associations with proximity to the mandibular canal. Methods: A retrospective cohort of 270 patients who underwent surgical extraction of mandibular third molars was analyzed. Preoperative panoramic radiographs were evaluated by three experienced surgeons to classify the tooth position (Winter classification) and proximity to the mandibular canal (Rood and Shehab classification). Postoperative complications (pain, swelling, trismus, paresthesia, hematoma, and hemorrhage) were assessed via standardized questionnaires and clinical records 7 days postoperatively. Data analysis included descriptive statistics and multinomial logistic regression. Results: Mesioangular and horizontal impactions were significantly associated with increased postoperative pain and swelling. Logistic regression indicated that the mesioangular position increased the odds of pain by 95% (odds ratio [OR] = 1.95) and swelling by 85% (OR = 1.85). The horizontal impact increased the odds of pain by 2.8 times (OR = 2.8) and swelling by 5.0 times (OR = 5.0). Tooth position was a significant predictor of postoperative complications (P = 0.007), whereas proximity to the mandibular canal, patient age, and the mandibular side were not. Root darkening emerged as a notable radiographic finding. Conclusions: The position of impacted mandibular third molars, particularly mesioangular and horizontal angulations, significantly influences postoperative pain and swelling. These findings highlight the importance of considering the tooth position in surgical planning to reduce complications. Although panoramic radiography is useful in resource-limited settings, cone-beam computed tomography is advised for complex cases or when vital structures are at risk.
Applicability of Willems method for age estimation in Brazilian children: performance of multiple linear regression and artificial neural network Letícia Tose Rocha, Mara Sampaio Ingold, Francine Kühl Panzarella, Bianca Marques Santiago, Rogério Nogueira de Oliveira, et al. Egyptian Journal of Forensic Sciences, 2022 Background Dental age estimation of children may be necessary in the clinical and forensic fields. In the former, it may contribute to the investigation of dental development and biological maturation. In the latter, dental age estimation may support the Court in several circumstances, such as adoption and unidentified bodies of deceased children. This study aimed to apply Willems method for dental age estimation of children from Southeastern Brazil. The second aim of the study was to test the performance of the method modeled with multiple linear regression (MLR) and artificial neural network (ANN). The sample consisted of 1000 panoramic radiographs of female (n = 500) and male (n = 500) Brazilian children. The individuals were evenly distributed through ten age intervals of 1 year from 6 to 15.99 years. Dental development was classified with the 7-teeth technique of Demirjian et al. (1973), followed by age calculation with Willems method (2001). The difference between chronological and estimated ages was quantified for the original Willems model and for the MLR and ANN models. Results For females and males, the overall difference found with Willems original model was 0.27 and 0.28, respectively. With MLR and ANN, the overall differences were 0.54 and 0.35, and 0.26 and 0.24, respectively. The ANN was able to reduce half of the mean error of female age predictions up to 100%. The same phenomenon occurred in 1/3 of the males. Despite the improvements of the ANN model to specific age groups, the original Willems model performed similar or better in 40% of the studied age intervals. All the models showed the worse age predictions in the interval between 15 and 15.99 years (p < 0.001). Conclusions Willems method remains optimal and applicable after 20 years since original development. The ANN model might be an option for future improvements (depending on sex and age interval).
