Panoramic radiographs are complementary exams to evaluate oral alterations in an early manner, these changes can be dental developmental anomalies, and post-eruption dental disorder. Aim: This study evaluated the findings in panoramic radiographs and correlated the variables of gender and dental location. Methods: A retrospective study was through the observation of 1.111 panoramic radiographs from the Radiology Department in Brazil. It was included patients from 5 to 79 years of age of both gender, and it classified the anomalies in shape, size, and number and post-eruption dental changes in and correlated with gender and location. Patients with syndromes were excluded from the sample. Results: The majority of the sample was composed of fameles 752 (67.7%), as to the frequency of dental developmental anomalies related lesions 684 cases (61.6%) and post-eruption dental disorder 567 (51.8%), in the radiographs. The most prevalent change was endodontic treatment (32.6%), followed by root dilaceration (25.9%), and included tooth (19.5%). The most prevailing alteration when correlated with the gender variables was the cyst root (p<0.01) in females, and orthodontic treatment (p=0.02) in males and the variable location in the mandible was root dilaceration, giroversion, impacted tooth, taurodontia, microdontia, and endodontic treatment (p<0.01). Conclusion: Our findings provide evidence that dental developmental anomalies e post-eruption dental disorder are frequent alterations in the population with particular characteristics of distribution by sex and location.

Introduction: Impaction is one of the most common tooth abnormalities which has multiple pathological consequences. The purpose of this study is to assess the prevalence of impacted and semi-impacted teeth and to determine the impaction angle of different teeth in patients referred to the maxillofacial radiology department of dental school, Mazandaran University of medical sciences in years 2013-2019.   Material and Methods: The panoramic radiographs of patients who were referred to oral and maxillofacial radiology department of Mazandaran dental school were observed. Impaction or semi-impaction angle of third molars were determined by Winter’s classification. Statistical analysis were conducted by using Chi-square test, Fisher’s exact test, Mann Whitney U test and Spearman correlation test (a= 0/05).   Results: 3200 panoramic radiographs were analyzed, and the prevalence of impaction, complete impaction and semi-impaction were calculated to be 25/8%, 3/7% and 23/6% respectively. The mesioangular impaction (48/3%) was the most prevalent kind of impaction. Statistically, age was correlated with the jaw involving tooth impaction (P=0/01), this correlation wasn’t observed about sex (P=0/161).    Conclusion: Impacted teeth were observed in approximately one third of the radiographs. Impaction was more common in the mandible and the most prevalent kind of impaction was determined to be the mesioangular impaction. As the impacted tooth can cause problems we conclude that they must be extracted at an early age.

Impacted Teeth

Introduction: Impacted teeth is complex anomaly of teeth eruption that requires a balanced approach not only in the differential diagnosis of its forms, but choice of rational methods of treatment. The aim: Optimization of the tactics of orthodontic-surgical treatment of patients with impacted teeth based on the development and implementation of computed tomographic indices (KT) and photometric indices (FM) of opening of surgical access (OSA) to crowns of impacted teeth Materials and methods: The results of treatment of 48 patients with delay of permanent teeth eruption have been analyzed. For an objective assessment of treatment results, a group of 24 (aged from 9 to 19 years old ) was formed. All 24 patients had typical clinical situation. Results: Orthodontic correction of patients envisaged, first of all, the elimination of obstacles in the way of teeth eruption, if necessary to provide space in dental arch and simultaneous treatment of associated bite malocclusions. Surgical exposure of impacted tooth crown was carried out and at the same time a triangular shaped guiding channel was formed, base of channel was at the impacted tooth and its angle finished into the dental arch. Precise dimensions and depth of the channel were preliminary planed on computed tomography slices with 3D reconstruction. Mean values of CT width (7,13±0,54mm), and length (6,42±0,78mm) of OSA and CT index (130,79±8,19%) of OSA to impacted teeth crowns were determined. Conclusion: To improve the quality of diagnosis and optimization of methodological approaches to treatment of patients with teeth impaction, we have proposed CT and FM OSA indices to the crowns of impacted teeth. The developed indices serve as specific reference points for optimization of diagnostic process, for reducing of probability of repeated surgical interventions and choosing the optimal path for instrumental orthodontic treatment of patients with impacted teeth

Osteolytic Lesions

The purpose of this article was to present a case report of 11–year old female patient with a large osteolytic mandibular lesion which healed after endodontic treatment. The patient was referred for radio diagnostics due to an incidental finding of a large osteolytic lesion of the area of the left lower first and second premolars in the panoramic radiograph taken before orthodontic treatment. CBCT was performed and the patient asked to have teeth 33-35 treated by endodontics before surgery. The patient missed the surgical appointment and when she reappeared several months later, the lesion showed signs of healing thus surgery were aborted. The presented case testifies to the observation that even large osteolytic lesions can heal after endodontic treatment without surgical approach.

Aim: To evaluate the periodontal status before and after orthodontic treatment and to analyze the confounding factors associated with it. Materials and Methods: The present retrospective study analyzed pre- and posttreatment records of a total of 60 patients. Intraoral digital photographs before and after the orthodontic treatment were used to measure the following three periodontal variables: (a) width of the keratinized gingiva, (b) gingival recession, and (c) the status of interdental papilla. The ImageJ 46 software imaging program was used to perform the required measurements. The clinical data were then analyzed in an association with the participants’ demographic data, the type of orthodontic tooth movement, and other confounding factors. The data obtained were manually entered into the statistical package and analyzed using a significance level set at P < .05. Descriptive statistics, paired t-tests, and Pearson’s correlation analysis were used to identify differences among the studied variables. Results: Among the 60 patients, the majority (66.7%) were females. Most cases of the treated malocclusion were Class II, and most patients underwent intrusion and retrusion movements. The width of keratinized gingiva increased for most sites of upper teeth. In contrast, the lower teeth showed a mix of improvement and compromised width of keratinized gingiva. As a measure of gingival recession, the difference of clinical crown height revealed the tendency toward a reduced clinical crown height for most sites. Upper left lateral incisors and canines showed significant values with regard to keratinized gingival width measurements and tooth movements such as extrusion and intrusion movements. Likewise, with regard to the clinical crown height, upper right central incisors showed significant differences when correlated with the interincisal angle, lower incisors to the mandibular plane, and upper incisors to the NA line. The upper lateral incisors also showed significant correlations to certain cephalometric measurements. Conclusions: The orthodontic treatment was found to exert a significantly positive impact on the surrounding periodontium, particularly in the upper canine areas. Likewise, various types of tooth movement were found to positively affect the periodontium.
