Abstract The role of lower third molars in lower incisor crowding is a debatable topic. Some believe the presence or eruption of lower third molars is associated with the crowding of mandibular incisors, others negate such association. Thirty-two newly debonded orthodontic patients, with ages ranging from 14-19 years, were randomly selected. No retainers were used for the lower dental arch. Removal of tight interproximal contacts of the lower anterior teeth was created and maintained by periodic abrasive stripping every 2-3 months, if needed. The cases were followed up for one year. Orthopantomographs (OPGs) and study casts were taken at debonding (post-treatment) and at the end of the one year follow up (post retention). Statistical analysis of the lower third molar conditions – erupted, unerupted, or missing with or without sufficient space for their eruption – versus re-crowding of lower incisors was evaluated using Fisher's Exact Test. The results of this pilot study revealed there was no significant correlation between the different conditions of the lower third molars versus lower anterior re-crowding in the absence of tight interproximal incisal contacts; however, a larger sample size is needed to verify such findings.

Orthodontic treatment, especially during the period of active growth, can significantly affect the development of the jaws and teeth. Treatment with extraction of molars is more complicated because the space that needs to be closed is larger than the premolar spaces and the time of treatment will be longer. However, in cases where we have a lack of space, teeth protrusion or dental asymmetry, and the extraction of permanent teeth is indicated, the damaged molars should be the first option for extraction when premolars are in better condition. The third molars in different ways are affected by orthodontic therapy. One of them is orthodontic treatment by applying the extraction of the third molars, this situation being widely explored. Extraction of third molar for orthodontic reasons is justified when it prevents the eruption of the second molar or otherwise affects the other teeth. The indications of extraction and selection of teeth to be removed depend on the specific aspects of malocclusion. Premolars are teeth that are usually extracted from orthodontic reasons, but this is not the rule and depends on individual treatment needs. The decision to correct the malocclusion with teeth extraction should be based on the ratio of the size of the dental arch with the size of the teeth, facial appearance and other factors arising from the diagnosis itself. Indications for extraction of the third molars during orthodontic treatment are: mandibular incisor crowding, if they in some way constitute a obstruction of orthodontic treatment as well as preparation for orthognathic surgery. The success of an orthodontic treatment involving the extraction of molars is directly related to the patient complaints and psychological profile, the absence of diseases and skeletal discrepancies, the professional experience as well as the fact whether the patient underwent previous orthodontic treatment with extraction. Patients with partially or completely non-erupted teeth are significantly more likely to have certain consequences: before, during or after the orthodontic treatment. Therefore, orthodontists need to raise patient awareness of these consequences in the context of orthodontic treatment.

<p><strong><em>Background:</em></strong><em> One of the most common inflammation disease in the oral cavity for the past few years is the aggressive form of periodontitis. Common signs of aggressive periodontitis is the mobility of teeth especially in incisive and first molars, and occuring mostly in young patient. Young patients whose losing her anterior teeth, are a real challenge for dentist and prosthodontist. Prosthodontist need to consider both functional and esthetic aspects. <strong>Objective:</strong> Rehabilitation of young adult patient with aggressive periodontitis by an interdisciplinary approach of orthodontist and prosthodontist. <strong>Case Description:</strong> A young woman, suffered from aggressive periodontitis with major complain of her teeth mobility, especially incisive and first molar in mandible. She had undergone periodontal treatment, but the result was failed. The anterior teeth in mandible need to be extracted, therefore patient wished not to be in edentulous state. As preliminary treatment, we choose immediate denture to replace the anterior mandible teeth. We faced difficulties in mandible, because her right canine weren’t in the proper dental arch. So we asked orthodontist to place fixed orthodontics in mandible, to get the canine back in the proper arch. We’ve chosen orthodontic treatment,because we didn’t want to extract the canine teeth. We evaluated in six months and after the canine back in the proper arch, we proceed to long span bridge in mandible as our definitive treatment. <strong>Conclusion:</strong> By not extracting the canine teeth, we got some advantages, especially patient psychically was happier with her own teeth. The collaboration with another dentistry field, provides us better treatment for patient. After treatment, patient had no complaints and was happy with her new smile.</em></p><p><strong><em>Keywords:</em></strong><em>  Prosthodontic rehabilitation, aggressive periodontitis, orthodontic treatment, esthetic</em><em>.</em></p><strong><em>Correspondence:</em></strong><em> Chaterina Diyah Nanik.

The aim of the study was to assess the influence of flap designs (Envelope flap (EF) and Szmyd flap (SF)) for impacted mandibular third molar extraction, on periodontal pocket depth (PPD), clinical attachment loss (CAL) and bone levels (BL) of second molar. Sixty patients indicated for third molar extractions with healthy second molars were allocated into two groups: EF and SF (n = 30). Third molars were assessed for angulation, root patterns, depth of impactions and relation with ramus (Pell and Gregory classification). Extraction of third molars was performed and PPD, CAL and BL around second molars at 0, 3 and 6 month (mon) follow-ups (FU) were assessed clinically and radiographically. ANOVA, Chi-square and Fisher’s exact test were employed to compare periodontal factors between EF and SF groups, considering p ≤ 0.05 as significant. Sixty participants with a mean age of 23.22 ± 3.17 were included in the study. Based on angulation, the most common impaction in the EF and SF groups was mesio-angular (EF, 50%; SF, 36.7%). Buccal and distal PPD showed a significant increase (p < 0.001) in both EF and SF patients from baseline to 6 mon. EF patients showed significantly higher distal and buccal CAL (6.67 ± 0.18 mm; 6.91 ± 0.17 mm) and BL (7.64 ± 0.16 mm; 7.90 ± 0.15 mm) as compared to SF patients (CAL, 6.76 ± 0.26 mm; 6.91 ± 0.17 mm-BL, 7.42 ± 0.38 mm; 7.34 ± 0.34 mm) at 6 mon FU. SF showed better soft tissue attachment (PPD and CAL) and bone stability (less bone loss) around second molars compared to EF after third molar extractions regardless of the patient, tooth and operator factors.

Latar belakang: suatu kasus impaksi gigi dapat menyebabkan maloklusi, dan kelainan oklusi akan semakin bertambah dengan bertambahnya usia. Impaksi gigi kaninus merupakan gigi kedua setelah gigi molar ketiga yang berfrekuensi tinggi untuk mengalami impaksi, persentasenya sekitar 12%-15% dari populasi. Gigi supernumerary adalah gigi tambahan/berlebih, sehingga jumlah gigi yang terbentuk dalam rahang lebih banyak dari jumlah normal. Terjadinya impaksi gigi kaninus dan supernumerary secara bersamaan jarang terjadi. Tujuan: Menambah wawasan du bidang bedah mulut minor, terutama dalam menangani suatu kasus impaksi gigi kaninus dan supernumerary untuk perawatan orthodonti. Kasus dan Penanganan: Dilaporkan seorang apsien, wanita, berusia 38 tahun yang baru menyadari kelainan maloklusinya dengan keluhan gigi depannya bertambah maju akibat adanya impaksi gigi kaninus dan impaksi gigi supernumerary. Pasien dikonsulkan dari Bagian Orthodonti ke Bagian Bedah Mulut untuk penanganan impaksi gigi kaninus dan supernumerary dengan kemungkinan untuk mempertahankan gigi kaninus memulai pembedahan. Dengan berbagai pertimbangan, penderita pada akhirnya menjalani operasi pengambilan gigi kaninus dan gigi supernumerary di Bagian Bedah Mulut RSGM Prof. Soedomo. Langkah-langkah diagnosis, operasi dan berbagai kemungkinan komplikasi juga turut disertakan di dalam pembahasan. Kesimpulan: Pengambilan gigi kaninus dan gigi supernumerary yang terpendam merupakan pilihan perawatan jika tidak memungkinkan untuk dilakukan exposure pada impaksi gigi kaninus pada maksila. Background: Impacted canines is the second most impacted tooth after third molar impaction, approximately 12%-15% of the population present with impacted canines. A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. The incidence of an impacted canines as a sequent with a supernumerary tooth is very rare. Purpose: The aim of this case report is to add more information about a minor surgery due to canine and supernumerary tooth impaction for orthodontic treatment. Case and Management: We reported a case of a woman, 38 years old who have noticed a malocclution through the forwardness movement of her anterior teeth, due to the present of impacted canine and supernumerary. The patient consulted from orthodontic department to oral and maxillofacial department for further assessment, treatment and also the probability for surgical exposure of impacted canine. We have decided to do odontectomy for the impacted canine and supernumerary tooth as well at Oral and Maxillofacial department, Prof. Soedomo Hospital. The diagnosis process, exposure of impacted canine considerations are also discussed. Conclusion: the odontectomy for impacted canine and supernumerary teeth had performed as last options if there is impossible to do an exposure of an impacted canine.

ABSTRACT Objective: We aimed to investigate the prevalence, distribution, angular position, and depth of third molar impaction in a Turkish orthodontic patient population. Materials and Methods: We retrospectively reviewed the panoramic radiographs, intraoral photographs, and dental casts of 207 patients (62 men and 145 women; age 20-39 years) who had undergone orthodontic treatment at a university department of orthodontics for impacted third molars (ITMs). A comprehensive chart review of all subjects was conducted. Patient and treatment-related data were recorded in a digital database for comparative analysis. Results: The prevalence of ITMs was 54.1%, and no statistically significant gender differences were evident (61.3% in men and 51.0% in women; P = 0.23). The frequency of maxillary ITMs was 49.3% (148 of 300 teeth) while that of mandibular ITMs was 50.7% (152 of 300 teeth). The most frequently observed angulations of impaction were mesioangular for the mandible (65.1%), and distoangular for the maxilla (64.2%). Of all the ITMs analysed, 61% were partially buried in bone and 39% were completely buried. Conclusions: Third molar impaction was evident in 54.1% of a group of Turkish orthodontic patients aged 20-39 years, and there was no statistically significant gender bias. Mesioangular and distoangular inclinations were the most common in the mandible and the maxilla, respectively.

Category: Ankle, Ankle Arthritis Introduction/Purpose: Recent advances in arthroplasty for the hip and the knee have motivated modern foot and ankle research to perfect the implant and technique for the optimal total ankle replacement. Unlike in the hip where different approaches can be done with the same implants, the approach of a total ankle is intimately associated to the prosthetic design. The anterior and lateral approaches have pros and cons regarding their respective soft tissue complications, osteotomy necessity, orientation of the bone cut and gutter visualization. While both have been studied independently, very few reports have compared both in the same setting. We set out to quantify the PROs and re-operations of both groups. Methods: A prospective study was conducted from a single center between 2014 and 2018 including a total of 64 total ankles performed by one of four fellowship-trained foot and ankle surgeon. A baseline dataset of their demographic as well as baseline scores (AOS, AAS & SF-36) was documented as well as at the 6 months and yearly mark post-operatively. Re-operations were also reported and coded in the local database. The approach was determined by the surgeon’s practice preference and patients were referred to surgeons as part of a central intake. Patients were included when they had a primary TAR in the timeframe noted and had a complete dataset up to at least the one year outcome. This cohort comprised 27 anterior and 37 lateral with balanced demographic for age (95%CI 63-67 yo) and gender (47% F). The lateral group had higher COFAS type arthritis, longer intraoperative time and adjunct procedures. Results: Comparing the two groups, it was noted that the anterior group had superior SF-36 scores at the one-year post- operative mark on both the physical and mental components. The difference was statistically significant and greater than the MCID. Otherwise, the two groups had similar AOS and AAS post-operative scores that were not statistically different. A total of 8 patients had a reoperation, 7 were from the lateral cohort and 1 from the anterior approach group. The lateral group had 3 surgical debridement for deep infection/wound complication, 2 ankle gutter/HO debridement and 2 lateral hardware removal. The anterior group had one ankle gutter/ HO debridement. Two of the above patients had two re-operations and one had three. Conclusion: This prospective pilot study outlines the early results of lateral versus anterior total ankle replacements. The risk of deep infection requiring reoperation was higher in the lateral group and the SF-36 scores one year after surgery were inferior to the anterior group. The lateral cohort had however significantly more pre-operative peritalar disease which was not balanced and likely affected those results. Patient experience based on PROs (AAS, AOS) otherwise is comparable. Future studies with longer prospective data need to be considered to have the power to draw significant conclusions.

Two cases of calcifying cystic odontogenic tumor (CCOT) of the dental follicle in an impacted third molar without clinical and radiological evidence are reported during routine histopathological examination. In both the cases left mandibular third molar was mesioangularly impacted with pericoronal radiolucency of less than 2.5 mm, which was not indicative of any pathology. As a routine protocol (which is not practiced widely) of our institution, dental follicles associated with extracted molars were sent for histopathological examination. Histopathological features were consistent with CCOT with pathognomonic ghost cell transformation of odontogenic epithelium. The patients were followed for one year with no recurrence. This paper emphasizes the importance of routine histopathological examination of dental follicles associated with asymptomatic impacted teeth without any clinical or radiographic evidence of follicular lesion.

Statement of the problem: restoring endodontically treated teeth (ETT) is one of the major treatments provided by a dentist. Glass fiber posts (GFP) showed good clinical performance during last few years.Aim of the study; to assess and compare the clinical as well as the radiographic performance of different types of ceramic crown systems used in restoration of maxillary anterior teeth over a cemented GFP and composite resin core.Materials and methods: 50 ETT with GFP were included in this study. These teeth were divided into four gropes (composite resin. Porcelain fused to metal (PFM), e. max and zirconia restorations). Both the clinical and radiographic assessments were done for the restoration at a period of one week, 3, 6, 9, and 12 months after composite build up and crown's cementations. All data were registered and analyzed by SPSS program using percentages and Kaplan-Meyer analysis. Fisher’s exact test was used for categorical values while log-rank test was used for descriptive statistical analysis.Results: the clinical assessment showed no changes in the one week, 3 and 6 months in the four groups. While during the 9 and 12 months, a movement of the crown margin under finger pressure was present in one case, loss or retention in 2 cases of zirconia, the periodontal status with violation of biological width was present in one case of PFM and finally the color changes were obvious in one case of PFM and 2 cases of composite restoration. All the restorations in the four groups had no radiographic changes in the one week and three-month assessments. While during six-month follow-up, a loosed of retention in one case of the zirconia crown was detected. At the 9 and 12 months, two cases showed recurrent caries at the cervical margin of the composite restoration, cases with periapical infection and other with loss of retention of the post were recorded in the PFM restoration.Conclusion: e. Max and zirconia all ceramic crowns showed better clinical and radiographic performance than the PFM and composite restorations over 12 months recall.

INTRODUCTION: Impaction may be defined as the failure of complete eruption into a normal functional position of one tooth within normal time due to lack of space in the dental arch, caused by obstruction by another tooth or development in an abnormal position.MATERIAL AND METHODS: A cross sectional descriptive study was conducted on 945 patients (males=591, females=354) aged between 18- 50 years of age who had mandibular third molars impacted. The difficulty index for mandibular third molar for angulation and depth was based on Winter’s classification (1926).RESULTS: The most common type of impaction seen was Mesio- angular with (32%) followed by horizontal 264 (27.8%), then followed by other types. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 23.0CONCLUSION: Impacted third molars are a common observation in routine dental practice. The impaction rate of third molars is higher as compared to other teeth in the dentition. The high prevalence found in the present study, with more than half of these Nepalese adult patients having at least one impacted third molar.
