Abstract

Aim: The aim of this study was to compare the periodontal status of impacted canines after 5 years following completion of the combined surgical and orthodontic treatment. Materials and methods: We examined 20 labially impacted canines and 20 palatally impacted canines at 5 years after the end of treatment. We assessed the periodontal status of these teeth. Results: Different outcomes were found regarding the probing depth and the amount of keratinized gingiva in the two mentioned groups of teeth. Conclusions: The assessed periodontal indices may signal the appearance of a periodontal disease around the teeth that were surgically and orthodontically treated

Abstract

Introduction: The imaging method of cone beam is an improved, extremely accurate computed tomography applicable in the whole field of dentistry. Due to its ability to locate the exact position of the impacted teeth, CBCT software has an important role in the management of difficult cases of impacted third molar. In some situations, the lower third molar is quite near to the inferior alveolar nerve that the surgical extraction can present a high risk of post-operative sensitive impairs of the skin and mucosa of the lower lip and chin on the same side. Presentation of case series: Our study tried to assess the contribution of CBCT in the pre-operative evaluation and further treatment of patients with impacted third molars in mandibular bone with high risk of inferior alveolar nerve injury. The paper presents three clinical cases showing positive signs on standard OPG, which exhibit indicators of a potential contact between the inferior alveolar nerve and the impacted lower third molars. For an improved exploration Dental CT Scan, DICOM image acquisition program, and 3D reconstruction with a special software were used. Conclusions: The study showed that compared with panoramic radiography, CBCT improve the evaluation of the surgical risk and allow a more accurate planning of surgery.

Abstract

Introduction: Masses of the head and neck comprise a variety of benign and malignant tumors and tumor-like conditions, which may present diagnostic challenges to the surgeon and pathologist as well. Fine needle aspiration cytology is considered to be a valuable diagnostic tool used for preoperative evaluation of various masses in the head and neck region. However, its role is quite controversial for salivary gland tumour evaluation. This study was aimed to evaluate salivary gland fine-needle aspiration cytology for sensitivity, specificity and diagnostic accuracy in our medical center.

Material and method: The present study included 58 patients with different salivary gland lesions who underwent preoperative fine-needle aspiration procedure followed by surgical procedure and histological examination. The cytological findings were compared with the final histological diagnosis and concordance assessed.

Results: Of the 58 cases with salivary gland lesions, most of them involved parotid gland (72.41%), 91.38% were neoplasms and 8.62% were non-neoplastic lesions. Out of 53 neoplasms, 39 were benign and 14 were malignant salivary gland tumors. The sensitivity and a specificity of fine-needle aspiration cytology in differentiation malignancies from benign lesions was 100% and 97.73% respectively. In some situations cytological features could not provide correct tumor characterization.

Conclusions: Fine-needle aspiration cytology is a simple and reliable technique for preoperative evaluation of salivary gland tumors with a high sensitivity diagnosis of malignant tumors, but a lower tumor type characterization. Due to the minimally invasive nature of the technique, fine-needle aspiration cytology offers valuable information for planning of subsequent therapeutic management.

Abstract

Objective: Regeneration is defined as a reconstruction of a lost part of the body in such a way that the structure and function of the lost tissue are completely restored. The aim of this study is to compare the clinical outcomes of intrabony defects treatment using regenerative periodontal therapy with enamel matrix proteins (Emdogain, EMD) with a control group.

Methods: Ten patients with chronic periodontitis were included in this randomized, controlled clinical study. Two groups received conservative periodontal therapy. In the test group, different teeth received regenerative treatment with EMD. In the control group teeth received solely conservative periodontal therapy. Pocket depth probing (PD) and bone reduction (based on X rays) were registered at baseline and after eight months in both groups. In the control group

Results: Both groups showed a significant reduction of PD. The teeth treated with EMD showed a significant attachment gain. Within the test group, the radiographic examination of the teeth treated with EMD showed no significant change, whereas the teeth in the control group showed significant bone reduction.

Conclusions: Intrabony defects in teeth treaded with EMD exhibit a substantially higher gain in clinical attachment and defect filling. The use of EMD in dental practice can prevent further bone loss.

Abstract

Aim: The aim of this study was to perform a clinical and statistical research on permanent impacted canine patients among those with dental impaction referred to and treated at the Oral and Maxillo-Facial Surgery Clinic of Tîrgu Mureș, over a four years period (2009-2012). Materials and methods: The study included 858 patients having dental impaction, and upon clinical records, different parameters, like frequency, gender, age, quadrant involvement, patient residence, associated complications, referring specialist and type of treatment, related to canine impaction, were assessed. Results: The study revealed: about 10% frequency of canine impaction among dental impactions; more frequent in women, in the first quadrant (tooth 13); most cases diagnosed between the age of 10-19 years; patients under 20 were referred by an orthodontist, those over 20 by a dentist; surgical exposure was more often performed than odontectomy. Conclusions: Canine impaction is the second-most frequent dental impaction in dental arch after third molars; it occurs especially in women. Due to its important role, canine recovery within dental arch is a goal to be achieved, whenever possible. Therefore, diagnose and treatment of canine impaction requires an interdisciplinary approach (surgical and orthodontic)

Abstract

Background: Inserting dental implants in severely atrophied jawbones is a great challenge for the dental practitioner. There are an increasing number of patients who choose dental implantanchored prosthetic restorations despite compromised bone quality and quantity. There have been numerous attempts in adapting implant design for the atrophic crestal bone. One-piece, needle-type basal implant design is a typical design for these cases. These implants are inserted in the remaining compact bone located in the basal aspect of the jawbones. If high primary stability is achieved, these implants are used for immediate loading protocol. From many points of view, this technique is based on contradictory principles compared to classic implant surgery and loading protocols. The aim of this study was to investigate the long-term success of basal one-piece short-diameter dental implants used for immediate loading protocol.

Materials and methods: A total of 56 dental implants were included in this study. Peri-implant bone loss was measured on orthopantomographs. Bone resorption was measured in millimeters in the first 6 and 12 months of functional loading.

Results: There were no failing implants in this period; average bone resorption was 1.59 mm after 6 months of functional loading and 2.05 mm after 12 months. Bone resorption was slightly higher in the mandible than in the maxilla.

Conclusions: Immediate implant loading protocol might be an attractive solution for fixed fullarch restoration using short-diameter one-stage basal implants, but long-term effects require further investigations.

Abstract

Background: Dental implants are useful tools and represent a widely spread technique for oral rehabilitation. Their long standingness is highly influenced by the mechanical and geometrical properties of the surrounding osseous tissue in which they are placed. In some unsuccessful cases though, the dental implant is exposed to masticatory forces and other functional acts, and osseous tissue may resorb near its vicinity, leading to the dental implants loss. We investigated the strain distribution inside the fixating substrate, given certain stages of its deterioration near the dental implants.

Material and methods: For our investigations we used cilindro-conical screw-type dental which were submitted to vertical forces between 0-1000 N. The dental implants were fixed inside a plastic material used in photo-elastic measurements.

To evaluate the strain distribution inside the fixing substrate, we used a non-contact, experimental investigation tool, the Video Image Correlation (VIC-3D) optical system. This system allows the implementation in the dental implants optimisation from stress-strain state point of view.

Results: The strain field distribution inside the fixating substrate was measured at three different levels of the dental implant, when it was loaded alone and in the case when there were loaded two dental implants simultaneously.

Conclusions: The most stresses are concentrated in the neck-area of the dental implant. If there are loaded two or more dental implants simultaneously, the distance between them influences strain distribution. The measurements were conducted in vitro and do not represent the in vivo conditions, but serve further important facts regarding biomechanical properties of dental implants.

Abstract

Aim. The purpose of this study was to evaluate the morphological aspects of dental follicles associated with impacted teeth and the immunoexpression of Ki 67 and p53, in the remaining epithelium from impacted third molars and canines. Another aspect was to identify the transformation of the remaining epithelium within the odontogenic lesions.

Material and method. We included in the study a number of 100 dental follicles, of which only 62 met the inclusion criteria. The immunohistochemical reactions were carried out in the Immunohistochemistry Lab at the Department of Histology of the University of Medicine and Pharmacy of Târgu Mureş. We counted 100 cells from the remaining epithelial islands from which we determined the percentage of labeled cells for both markers. After this all data were subjected to a statistical analysis.

Results. Out of the 62 specimens 44 were from females and 28 from males. Positive results were obtained for the two markers but not for all cases. We have also found a positive correlation regarding the immunolabeling of the two markers (p=0.002 in canines, p=0.0001 in molars). Median values for ki67 were statistically significantly higher than the values for p53 for both types of dental follicles.

Conclusions. Both markers were expressed in the remaining epithelial islands. The stronger expression of Ki67 in the follicles of impacted molars can demonstrate the higher frequency of odontogenic cysts in this area.
