Ectopic third molar in the mandibular sigmoid notch: report of a case and literature review

Purpose: To evaluate the etiopathogenesis, clinical features and surgical approaches for removal of ectopic third molars in the mandible. Methods: We report a case of an impacted mandibular third molar dislocated on mandibular sigmoid notch. 20 cases of ectopic mandibular third molars reported in the English-language literature, identified from Pubmed and Medline databases are also reviewed. Results: Among the 20 article reported in the presented study, ectopic third molars were generally located in the condylar region. The common symptoms of the clinical examination were pain, trismus, swelling, temporomandibular joint syndroms or no symptoms. Conclusions: Ectopic third molar may be asymptomatic initially with clinical manifestations, later on as adjacent structures are affected. The surgical approach must be carefully planned for the aim of choosing the more conservative technique that produces the minimum trauma to patients

Comparison of the effects of rapid maxillary expansion and surgically assisted rapid maxillary expansion in the sagittal, vertical and transverse planes

Objective: The aim of this study was to evaluate and compare the effects of rapid maxillary expansion (RME) and surgically assisted RME (SARME) in the sagittal, vertical, and transverse planes. Study design: Orthodontic records of 28 patients were selected retrospectively and divided into two treatment groups. Group 1 comprised 14 patients (4 boys, 10 girls, mean age 14.2 ± 0.74 years) who had been treated with RME. Group 2 comprised 14 patients (4 boys, 10 girls, mean age 19.6 ± 2.73 years) who had been treated with SARME. Measurements were performed on lateral and posteroanterior cephalograms and dental casts obtained before (T0) and after (T1) expansion. Results: Statistically significant differences were found in soft tissue convexity angle, anterior face height, and upper nasal width in group 1, and in U1-NA length and posterior face height measurements in group 2 (P<.05). In both groups significant increases were found in interpremolar, intermolar, maxillary, and lower nasal widths and in anterior lower face height (P<.01). Statistically signifificant intergroup differences were found in the ANB angle (P<.05) and maxillary intercanine (P<.01) measurements. Conclusion: With both RME and SARME, successful expansion of maxillary dentoalveolar structures and nasal cavity and palatal widening were achieved. Sagittal plane effects of SARME were similar to those of RME on dental skeletal and airway measurements. © Medicina Oral

The use of platelet-rich fibrin (PRF) and PRF-mixed particulated autogenous bone graft in the treatment of bone defects: An experimental and histomorphometrical study

Background: Various materials and techniques have been developed to facilitate bone healing process and reduce its healing period. In recent studies, it is pointed out that, platelet-rich fibrin (PRF) which is derived autogenously from the own blood of the individuals, increase regeneration and accelerate the healing of the wound, due to the consisting various growing factors. The aim of the experimental study is to evaluate the efficiency of PRF and PRF/autogenous graft combination on bone healing in different time intervals. Materials and Methods: A total of 24 skeletally mature New Zealand rabbits were used. Animals were divided randomly into two groups. Two bone defects with a diameter 3, 3 mm were created on the right and left tibia in all group animals. Only particulate autogeneous bone graft, only PRF, combination of PRF and autogeneous bone graft and empty bone cavity, were performed to all animals. The animals in the first experimental group were sacrificed after 30 days. The animals in the second experimental group were sacrificed after 60 days from the operation. Histomorphometrical and statistical analysis was performed. The data were analyzed using Tukey test (P < 0.05 for osteoblast number, P < 0.01 for osteoclast and new bone area values). Results: Histomorphometrical analyzes showed that either PRF used alone or used in conjuction with autogenous bone graft, PRF accelerated the healing of the bone defects. There were statistically significant differences in osteoblast, osteoblast and new bone area values in PRF alone and autogenous graft with PRF than the other groups. Conclusion: Our preliminary result demonstrated that PRF increase new bone formation and has a positive effect on early bone healing

Comparison of psychosocial and aesthetic features of class III malocclusion after orthognathic surgery: Conventional approach versus surgery-first approach

The aim of this study is to investigate and compare the changes in psychosocial status, self-esteem, and quality of life in patients treated with conventional and SF approaches. 14 patients (mean age 23.04§3.36; 9 male and 5 female) who met the inclusion criteria were included in the SF group; 18 patients with class III malocclusion (mean age 29.27§3.78; 9 male and 9 female) were included in the COS group. In the research protocol, the first questionnaires were carried out 2 weeks before surgery (T0); second survey approximately 4 weeks after surgery (T1); and the third one was done to patients after the treatment was completed (debonding) (T2). In our study, Orthognathic Quality of Life Questionnaire (OQLQ), Pyschosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), Oral Health Impact Profile (OHIP-14), Beck Depression Inventory second edition (BDI-II) and Rosenberg Self-Esteem Scale (RSES), surveys were conducted. No statistically significant difference was observed in all of the PIDAQ parameters and most of the OQLQ parameters within the COS and SF groups (P>0.05). When the BDI II results were examined, different trends in scores were observed between the two groups, and this difference was found to be statistically significant (P<0.05). In the SF approach, progressive improvement was detected in the patients in terms of psychosocial and quality of life in the early period of treatment. The greater improvement in psychological and social characteristics in the SF approach compared to conventional orthognathic surgery may also be associated with a shorter treatment time.No sponso

Impacted tooth in mandibular fracture line: Treatment with closed reduction

Purpose: Most mandibular fractures occur because of blunt trauma. In some cases, the mandible can be weakened by the presence of an unerupted or impacted tooth. The fate of this tooth in the fracture line and its effects on bone healing remain an important outcome event

SEMENTO-OSSİFİYE FİBROMA: OLGU RAPORU [Cemento-Ossifying Fibroma: Case Report]

ÖZET Fibro-osseöz lezyonlar, kemiğin fibröz bağ dokusu ile yer değiştirmesi ile karakterize lezyonlardır. Semento-ossifiye fibroma, genellikle mandibulada ortaya çıkan benign fibro-osseöz bir lezyondur. On yedi yaşındaki bayan hasta mandibula sağ molar bölgesindeki ağrı ve şişlik şikayeti ile kliniğimize başvurdu. Klinik, radyografik ve histopatolojik bulgulara dayanarak semento-ossifiye fibroma tanısı konuldu. Anahtar kelimeler: Fibro-osseöz Lezyon, Semento-ossifiye Fibroma, Mandibula, Rekkürens ABSTRACT Fibro-osseous lesions are characterized by the replacement of bone by a benign connective tissue matrix. Cemento-ossifying fibroma is a benign fibro-osseous lesion that occurs mostly in mandible. A 17-year-old woman was referred to our clinic with a complaint of pain and swelling in the right molar region. Based on clinical, radiographic and histopathological evaluation the diagnosis was concluded as cemento-ossifying fibroma.
