Karpitsaris Nikolaos is a postgraduate student, currently final year resident at the department of Orthodontics, Marmara University of Istanbul. He graduated from Aristotle university of Thessaloniki and worked in dental clinics in Greece and Germany as a general dentist before choosing the path of Orthodontics. He believes that a perfect smile is the prettiest thing you can wear. His main interests include lingual orthodontics, orthognathic surgeries and modern treatment modalities.

Statement of the Problem: In recent years, the percentage of adult orthodontic patients has arisen. Adult patients prefer lingual braces more than the labial ones due to esthetic reasons. Lingual appliances can be comparable with labial appliances.\r\n\r\nAim: Among patients receiving lingual and labial orthodontic treatment, we aim to investigate the: changes related to “oral health related quality of life”, changes related to “self-esteem” and oral impacts during treatment.\r\n\r\nCase: A pair of female adults (twins) were referred to our clinic with same chief complaints of minor crowding and unesthetic smile. They had no medical history. Examination revealed skeletal Class I relationship, normal profile and minor crowding in both arches. One of them underwent orthodontic treatment with buccal fixed orthodontic appliances. The other had orthodontic treatment with 2D lingual fixed orthodontic appliances.\r\n\r\nMaterials and Methods: Our case is based on questionnaires being delivered to the patient at every appointment. Three proven and valid questionnaires were delivered: Ohip-14, Rosenberg Self-Esteem Scale, VAS. Their answers were used to quantify the differences between the two different treatment modalities throughout treatment.\r\n\r\nResult: Esthetically pleasing and ideal dental and skeletal occlusion was achieved in both cases. The patient with the lingual treatment showed better response regarding his quality of life and psychology. \r\n\r\nConclusion: This case shows a successful orthodontic treatment plan in both methods, with the lingual treatment playing a truly important role in the patient’s everyday life and psychology.

Case Description: A 60-year-old partially dentate man presented with generalized moderate tooth wear affecting both arches due to a combination of chronic alcohol intake, diet related factors and parafunctional habit. The patient reported a history of increasing sensitivity to cold and wanted to improve overall dental appearance as they appeared clinically short. He had a shortened dental arch (SDA) in the upper arch with a minimally restored lower dentition, both exhibiting signs of interproximal and occlusal enamel wear with cervical abrasion. He had edge-to-edge class III occlusion with loss of occlusal vertical dimension (OVD) but there was sufficient freeway space and no dento-alveolar compensation due to relatively rapid rate of tooth wear. He had adequate inter-arch space for restoration replacement and a new OVD of 3mm was decided after articulation in retruded contact position. \r\n\r\nTreatment outcome: Direct composite build ups were carried out on upper and lower 4-4s and a hard-occlusal splint was made post-operatively. He was very satisfied with the overall aesthetics and immediate reduction in sensitivity. 3 weeks later, he had adjusted well to the new occlusion. \r\n\r\nDiscussion: The main aim of the treatment was to identify risk factors and introduce preventative regime tailored to patient’s need in order to prevent future caries and minimize further tooth wear. It is therefore important to review the patient every 6 months to monitor wear facets and review alcohol intake in order to increase the longevity of the restorations. Survival rate of these composites can be predicted as moderate to long term as 8 occluding unit allows a stable occlusion and sufficient enamel and clinical height gave maximum surface area for bonding which increases overall durability. Minimally invasive technique was the preferred choice over indirect restorations due to the patient having moderate wear only.

Introduction: Periapical inflammation develops as a response to the microbial flora of the pulp and the sub-products of the bacteria that infiltrate the periapical tissues and stimulate the immunological response of the host. Treatment options for the periapical lesions vary. The present case report refers to the treatment of a substantial periapical lesion on the upper jaw through conservative endodontic treatment. rnrnCase report: A 50-year old female patient with a non-significant medical history was referred to the Dental Department of Aristotle University of Thessaloniki. Her chief complaints were the persistent pain of the upper right central and lateral incisor region and swelling of the respective area. Clinical examination showed pain with percussion and palpation. The radiological examination revealed a large periapical lesion in the region of elements 11-12. The diagnosis was chronic apical periodontitis and endodontic treatment was decided to be performed on both upper right central and lateral incisor. The endodontic treatment of the upper right lateral incisor was performed in the postgraduate clinic of the Endodontics Department of Aristotle University of Thessaloniki. A combination of hand (k-files, Dentsply Maillefer) and rotary files (Mtwo, VDV Dental, Munich, Germany) was used. NaOCl 3.5% was used for irrigation and Ca(OH)2 paste was used between sessions. It is worth noting that endo aspirator was used with significant results, as purulent exudate was being drained for approximately 20 minutes. Obturation was performed with Gutta-Percha and AH26 sealer by lateral condensation technique. Recalls were conducted 1, 3, 6, and 12 months after the treatment that revealed healing of the periapical lesion. rnrnConclusion: The present case confirmed, along with previous reports, that even large periapical lesions can respond to conservative endodontic treatment of the correct therapeutic approach is followed.rn

Background: Segmental odontomaxillary dysplasia (SOD) is a rare nonhereditary, developmental disorder usually affecting the posterior maxilla. Clinical presentation consists of unilateral, painless expansion of the alveolar process with hypoplastic or missing premolar teeth in the affected region. rnrnPresenting problem: A 7-year old female was referred for assessment of a swelling in the upper right quadrant. Intra-oral examination revealed a firm bony swelling distal to upper right deciduous canine, as a result of buccal and palatal expansion of the maxillary alveolus only. Abnormal shaped deciduous molars were partially erupted and palatally displaced. The remaining dentition appeared normal.rnrnClinical management: Radiographic examination revealed mesial-distal separation of URD and URE with possible bone abnormality and missing upper right premolars. A cone beam CT scan was requested to exclude other causes of delayed eruption and provide baseline information. The patient was referred to the Paediatric Dentistry department, where a provisional diagnosis of SOD was made. Differential diagnoses include regional odontodysplasia and fibrous dysplasia (FD). SOD differs from FD in that the abnormality is restricted to the alveolus and odontogenic tissues. An incisional bone biopsy of the lesion confirmed the diagnosis of Segmental odontomaxillary dysplasia and continued monitoring of development is essential.rnrnDiscussion: Segmental odontomaxillary dysplasia is a rare condition, with less than 50 cases reported in English written literature. It usually presents in early childhood, due to the impeded or delayed eruption of the primary molars. The aetiology is unknown and future management will involve surgical, orthodontics and paediatric dentistry input with essential monitoring.
