    Adenomatoid hyperplasia of the oral cavity: a diagnostic dilemma
    (Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Bozkurt, Poyraz; Diş Hekimliği; Diş Hekimliği Fakültesi
    Purpose: This review study presents literature review and discusses the clinical significance of Adenomatoid Hyperplasia; a commonly misdiagnosed lesion. This rare entity has been seldom presented and is not well enough described in the literature. Methods: Only 15 reports with 95 cases could be attained during the online literature search using the keywords: Adenomatoid, Tumor, Hyperplasia, Minor salivary Glands. Results: Data revealed a tendency towards the male gender. Age distribution of patients did not reveal a tendency towards a specific age group but presented a peak incidence in the 4th and 5th decades. Location data revealed a tendency towards the palate, especially the hard palate. Most of the presented cases were asymptomatic and the most common initial diagnosis made was salivary gland tumor. Conclusion: Adenomatoid hyperplasia of the oral cavity may resemble a wide range of pathologies. In order to differentiate and to achieve a correct diagnosis, histological evaluation is fundamental.

    Brown tumor of the mandible as an ınitial presentation of hyperparathyroidism
    (Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Önder, Merve; Diş Hekimliği; Diş Hekimliği Fakültesi
    The paper presents a brown tumor case related to secondary hyperparathyroidism in an end stage kidney disease patient undergoing dialysis treatment. The interesting feature of the case is that the primary clinical presentation of the condition was a mild swelling in the attached gingiva of a mandibular molar tooth. Medical practitioners should be alert to the fact that some pathological conditions may have an initial presentation in the oral cavity. Thus, a thorough and careful examination of the oral mucosa with the accompanying dental radiographs of patients, should be noted and studied in all cases, where available.

    Investigation of water absorption and color change of ındirect composite resins
    (Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) İskender, Nur; Diş Hekimliği; Diş Hekimliği Fakültesi
    Purpose: Since conventional composite resins have some disadvantages such as polymerization shrinkage and secondary caries formation, indirect restorations are preferred in cases where tooth tissue loss is high. The aim of this study is to examine the water absorption and color change of indirect composite resins in different beverages. Materials & Methods: In the study, 40 specimens (10×2 mm) were arranged from each composite using three indirect (Signum Composite, Signum Ceramis and Gradia Plus) and one conventional (GrandioSO) composite resin. After the specimens were polished, they were used for water absorption and color change test. The water absorption test was performed through keeping them in water for 7 days as specified in ISO 4049:2009. Samples were kept in coffee, tea and distilled water for 7 days in order to examine color differences. The water absorption and color change values of the composite resins at the end of the 7th day were appraised using one-way analysis of variance (ANOVA) and Tukey’s test (p<0.05). Results: While there was no statistically considerable difference between the water absorption data of the indirect and traditional composite resin materials we used in the study (p>0.05). When the color changes of resin-containing composites in water, coffee and tea were examined, traditional composite resin (GrandioSO) showed statistically less color change than indirect composites in water, coffee and tea (p<0.05). Conclusion: Although indirect composite resins showed similar water absorption with conventional composite, they showed more color change than conventional composite. The highest color change in indirect composites was seen in coffee solution. Particle size of the indirect composites do not affect water absorption, but the decrease in particle size of composites shows less color change.

    Loose ıntra-articular body in the temporomandibular joint: case report of a successful conservative management
    (Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Del Rey, Yumi Chokyu; Diş Hekimliği; Diş Hekimliği Fakültesi
    Loose intra-articular bodies are a rare finding in the temporomandibular joint. Surgical removal of the loose bodies isoften described as the only treatment option; however, it presents possible postoperative complications. The aim of thispaper is to report the successful conservative management of a temporomandibular disorder associated with a singleloose intra-articular body. A 62-year-old woman presented with pain in the right temporomandibular joint andpre-auricular region, limited mouth opening and open-lock episodes. Panoramic radiography and cone-beam computedtomography exams revealed the presence of a single loose body located anterior to the right condyle. Magnetic resonanceimages showed bilateral anterior disc displacement without reduction. A non-invasive approach consisting of an occlusalsplint and low-level laser therapy associated with home-based physical therapy was performed for management ofclinical signs and symptoms. The patient was followed up for 2 years and presented significant pain reduction andimprovement in the range of mandibular movements. The combination of conservative therapies may be an alternativefor surgical intervention to control pain and improve mandibular function in patients with temporomandibulardysfunction associated with a loose body in the temporomandibular joint.

    The prevalance and radiographic evaluation of mandibular second premolar migration: a retrospective study
    (Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Kaya, İlhan; Diş Hekimliği; Diş Hekimliği Fakültesi
    Purpose:To investigate the prevalence and radiographic characteristics of migrated mandibular second premolars byusing panoramic radiography.Materials & Methods:The previously taken 27758 panoramic radiographs were evaluated regarding the determining theprevalence of mandibular second premolar migration. Thirty-six radiographs were excluded from the study due to notproviding the inclusion criteria. 27722 radiographs were evaluated retrospectively by the same operator. In the diagnosisof migrated teeth, radiographic features and demographic characteristics were recorded.Results:Nine migrated second premolar teeth were detected in the evaluation of all the radiographs (%0.03). The meanage of the cases was 37 years. All the migrated teeth were impacted, unilateral and the average distance between normaland migrated location was 41 mm. In most of migration case (in 6 case) absence of first permanent molar tooth wasobserved.Conclusion:It is concluded that, if the mandibular second premolar tooth are not located at physiologic position on thedental arch, a panoramic radiographic examination should be recommended to view all the jaws and related structures.Early detection of dental migration may be beneficial to prevent the possible further complications.

    Treatment management with long term follow-up in late-admitted traumatized permanent ıncisors: case series
    (Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Yüksel, Burcu Nihal; Diş Hekimliği; Diş Hekimliği Fakültesi
    Traumatic dental injuries are particularly common in school-age children and often occur in the anterior region. Process management of cases is possible with alternative treatments according to the root development levels. In this case series, it is aimed to present the treatment and 2-year follow-up of permanent anterior teeth with traumatic dental injuries. Case 1: 8-year-old patient, who had a bicycle accident 20 days ago, was diagnosed with extrusion of # 31. Due to late admission to the clinic was in the late period, no repositioning procedure was applied to the tooth. Regenerative endodontic treatment was done. During the radiological follow-up, the apex was closed in the 12th month; however, it was observed that obliteration started in the root canal at the 24th months. The case is still being followed up at regular intervals. Case 2: A 13-year-old patient, who had a traffic accident 3 days ago, was diagnosed with subluxation in #11, and a root fracture was detected in the apical third of #21. In #21, root canal treatment was applied to the coronal part of the fragments. After the diagnosis of pulp necrosis in #11 in the 2nd month of the follow-up period, root canal filling was applied. During the follow-up period, no pathology was detected and no granulation tissue was formed between the fragments in #21. In traumatic dental injuries, long-term follow-up, well-timed endodontic treatments and material selection play an important role in success. With regenerative endodontic treatment, successful results can be obtained even in treatments applied in the late period.
