“…In the present study CBCT were used for diagnosis, preoperative evaluation of the mandibular radicular cyst, and its relation to adjacent anatomical structures. This was following a study performed by Shweel M. et al in 2013 (21) who concluded that CBCT was very helpful in good preoperative planning and preparation as it helped in deciding the best approach for lesion enucleation and the incisions were precise to include the lesions.…”

INTRODUCTION: piezosurgery device was originally developed for the atraumatic cutting of bone as it produces microvibrations and specific ultrasound frequency (25-29 kHz). This new ultrasonic cutting method will be an alternative to conventional methods of oral surgery. OBJECTIVES: This study compares the use of piezosurgery and conventional technique in mandibular radicular cyst enucleation and this was estimated by clinical and radiographic analysis. MATERIALS AND METHODS: This study was conducted on fourteen patients selected from the Outpatient Clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Alexandria University. Patients with radicular cyst in jaw region were diagnosed clinically and radiographically. The patients were randomly divided into two groups, seven patients were treated using piezosurgery and other seven patients were treated using conventional surgical procedures. Intraoperative and postoperative evaluation was carried out to monitor soft tissue damage, manipulation complexity, pain, infection and tissue dehiscence at 1 st , 2 nd , 7 th day and after one month postoperatively. The bone healing and bone density was determined radiographically after 3 and 6 months postoperatively using Cone Beam Computed tomography. RESULTS: no soft tissue damage or manipulation complexities were observed in both groups, less bleeding was observed intraoperatively in piezosurgery group. Healing was uneventful with no signs of dehiscence in piezosurgery group with lower pain score than in control group. There was a significant decrease in the surface area of the bone defect in the piezosurgery group compared to control group along the follow up period. The improvement in the bone density was greater in the piezosurgery group than in the control group, with percent of difference 33.42% on the 3 rd month and 63.84% on the 6 th month. CONCLUSIONS: Piezosurgery is effective in cyst enucleation as it accelerates bone healing and reduces intraoperative and postoperative complications.

“…We agree with Huumonen et al [ 30 ] and Cohenca et al [ 31 ] when they say that the CBCT image allows in-depth observation of a determined region, eliminating overlapping and so avoiding one of the main limitations of X-rays, the lack of depth. CBCT also offers advantages over Multislice Computed Tomography, including lower radiation emissions, lower cost, and greater accuracy in detecting thinning and/or perforation of the buccal plate and tooth displacement [ 32 ]. However it should be noted that CBCT presents the disadvantage of not being indicated for soft tissue analysis.…”

“…Imaging is an essential part of preparation for most surgical procedures [ 18 ]. Preoperative examination of odontogenic lesions prevents complications in surgery and functional deterioration after surgery and reduces surgical stress [ 32 , 36 ]. In surgical planning for a dentigerous cyst, it may be necessary to measure the lesion from different angles [ 28 ], requiring more advanced radiological imaging.…”

Diagnosis and preoperative planning are critical in the execution of any surgical procedure. Panoramic radiography is a routine method used in dentistry to assist clinical diagnosis; however, with this technique 3D anatomical structures are compressed into 2D images, resulting in overlapping of structures which are of interest in the diagnosis. In this study we report the case of a patient who presented with a dentigerous cyst of expressive dimensions in the body of the mandible region. The surgery was planned and executed after observing the margins of the lesion by Cone Beam Computed Tomography (CBCT). We conclude that CBCT is a precise method to help diagnosis; it provides greater accuracy in surgical treatment planning through 3D image display, allowing more effective results.

“…Several intraoral and extra oral radiographic techniques such as periapical, occlusal, and panoramic views were available but these techniques have several limitations including two-dimensional image of three dimensional subject, insufficient visualization, superimposition, and distortion, which lead to underestimated assessment of the lesion. Recently the introduction of CBCT scan solves the drawbacks of the old radiological methods (15) . In this study, comparing the radiographic data to intraoperative findings of the lesions showed that CBCT was an effective method in radiographic diagnostic assessment of the cyst and cystic like lesions.…”

Background: Preoperative radiographical assessment of the maxillofacial lesions is of a great importance in guiding the surgeon during surgical procedure in reducing post-operative complications. This study highlighted the application of CBCT scan in the assessment of maxillofacial cystic and cystic like lesions as a part of advanced radiology Materials and methods: A total of 20 patients (15 males and 5 females) participated in this prospective study. CBCT scan (Kodak 9500 CBCT) with (DICOM) software utilized to perform scanning to all patients in order to assess lesion extension, morphological features and it's relation to the adjacent vital structures. Results: In this study, the total cystic and cystic like lesions involving the maxilla and mandible were (20) lesions. Statistical analysis of the collected data showed no significant differences between the radiographical records and surgical findings regarding diagnostic accuracy of the lesions. Conclusion: The validity of the CBCT in the assessment of maxillofacial cystic and cystic like lesions was similar to the surgical findings regarding lesion extension, expansion, perforation of buccal/or lingual plates, and relation to the adjacent vital structures.
