Summary Background Assessment of orthodontic treatment outcomes such as treatment duration in patients with hypodontia are lacking. Objectives To assess the overall treatment duration of cases of bilateral absent upper lateral incisors treated with either orthodontic space closure (SC) or space opening (SO). The secondary aim was to determine factors which influence overall treatment duration. Subjects and methods A retrospective cohort study was undertaken within the Orthodontic department at Kings College Hospital NHS Foundation Trust. Consecutively treated patients between 2008 and 2018 with bilateral absent upper lateral incisors were identified from clinic lists, clinical logbooks, and multidisciplinary clinics. All study data variables were collected by a single investigator using a pre-specified data collection sheet. Results In total, 52 cases were included, 29 in the SC group and 23 in the SO group. Overall non-extraction treatment was favoured (P = 0.001) with differences in restorations provided post-treatment evident (P = 0.01). Although not statistically significant, the mean overall orthodontic treatment duration was less in the SC group 25.7 months (SD 7.6) compared to the SO group 27.4 (SD 6.1). Overall treatment duration was reduced if treatment was carried out on an extraction basis (−7.02, 95% CI: −11.93, 2.11, P = 0.01) but increased as the amount of crowding in the lower arch increased (0.89, 95% CI: 0.08, 1.71, P = 0.03). Conclusions Within the study limitations, there is no difference in the overall treatment duration between both treatment approaches. Treatment duration is reduced in both SO or SC treatment plans if extractions are undertaken. The presence of lower arch crowding increases the duration of treatment.

Introduction: Due to the fundamental role of esthetics in the outcomes of dental treatments, especially in the anterior region (esthetic zone), the necessity of considering the matter of esthetics in clinical studies has become into focus in the current era. The aim of this study was the evaluation of esthetic outcomes of two treatment protocols in the treatment of congenital uni-lateral missing of maxillary lateral incisors as well as patient satisfaction from the treatment outcomes. Methods: in this study the sample size was 24 people (16 women and 8 men), These individuals sought dental treatment for replacement of the congenitally missing maxillary lateral incisor. Convenience sampling method was used and patients were divided into two groups regarding the kind of treatment they received. The two treatment protocols included: 1. Space closure by means of orthodontic treatment and then reshaping the canines; and 2. Space regaining by means of orthodontic treatment and replacing the lateral incisor with dental implants. Photographs of patients were acquired from the frontal view with retraction of the lips using digital cameras. Photographs were evaluated for Pink esthetic score. Results: No significant difference was detected between the two study groups in the evaluated factors in this study. Conclusion: The results of this study indicated that there is no significant difference in esthetic results in the two groups. Furthermore, both groups lead to similar results in patient satisfaction from treatment outcomes.

Abstract Objective: To investigate the influence of radiographic position of palatally impacted canines on the length of treatment for orthodontic alignment. Materials and Methods: Treatment records of 45 consecutive successfully treated patients (36 unilateral, 9 bilateral) with ectopic palatal canines treated with surgical exposure and orthodontic traction were analyzed. The sample was based on orthodontic referrals over a 3-year period in Kent and Canterbury Hospital, UK. The duration of treatment was related to radiographic parameters including the height of the impacted canine, angulation of the long axis to the upper midline, mesiodistal position of the canine tip relative to the midline and adjacent incisors, and the anteroposterior position of the canine root apex. Results: Using multiple stepwise regression analysis, the horizontal position of the canine crown relative to adjacent teeth and maxillary dental midline showed a statistically significant correlation with the duration of treatment (P =.042), explaining 7.7% of the overall variance. However, treatment duration was found to be independent of the initial canine angulation (P = .915), vertical height (P =.065), and position of the canine apex (P = .937). Conclusions: Accurate prediction of treatment duration for orthodontic alignment of palatally impacted maxillary canines is difficult. However, the mesiodistal position of the canine may be a useful predictor of treatment duration. (Angle Orthod. 2009:79;442–446.)

This descriptive type of cross-sectional study of 72 cases of uterine rupture was conducted over 1 year (from September 2006 to August 2007) in the department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital, Bangladesh to evaluate the maternal outcome of different types of surgery, to assess the maternal mortality and maternal morbidity. All cases of ruptured uterus which were received & treated and did not die within 30 minutes of admission are included in the study. Data were collected by preformed data collection sheet. The results showed that the common age groups were between 20-30 years in 31(68.00%) cases. Among all ruptured cases, 6 cases (8.33%) were Primigravida, 52 cases (72.22%) were between gravida 2nd to 4th and 14 cases (19.44%) were gravida 5th or above. Among all cases, 66 cases (91.66%) required blood transfusion; Subtotal hysterectomy was done in 36 cases (50.00%), total hysterectomy in 4 cases (5.56%), and repair of the rent in 32 cases (44.44%). Associated operations were done along with repair or hysterectomy in 13 (18.05%) cases. Postoperative complications were found in 23 (31.94%) cases. The shortest stay was 8 days & the longest stay was 62 days. The hospital staying was about 2 weeks in 48(66.70%) cases. Among 10 death cases (13.90%) maximum patient died within first 5 hours. The causes of maternal death were due to septicemia, renal failure and shock in 20%, 30% and 50% respectfully. CBMJ 2016 January: Vol. 05 No. 01 P: 20-26

ABSTRACT Objective: To present a patient treated with submerging autotransplantation (SA) of an immature premolar and subsequent orthodontic space closure (OSC) and to report a 10-year follow-up result. Case and Method: A 10-year-old boy had multiple missing premolars with an asymmetric pattern (maxillary right first and second premolars, teeth 14 and 15; maxillary left second premolar, tooth 25; and mandibular right second premolar, tooth 45). After considering several treatment options, tooth 35 with immature root development underwent SA into the missing site of tooth 15 at a depth 5 mm below the occlusal plane and was stabilized with sutures to create a symmetric missing condition of the premolars in the four quadrants. Results: Three months after autotransplantation, spontaneous eruption of the transplanted tooth was observed. Nine months after autotransplantation, presence of the lamina dura of the transplanted tooth was confirmed with a periapical radiograph. Active orthodontic treatment was initiated to reduce lip protrusion by closing the missing spaces of teeth 14, 25, 35, and 45 and to correct dental midline deviation. After 33 months of active orthodontic treatment, Class I canine and molar relationships were obtained. During the 10-year follow-up, the pulp vitality of the transplanted tooth was maintained without any pathologic findings, including root resorption or pulp canal obliteration. Conclusions: In a patient with lip protrusion and multiple congenitally missing premolars with an asymmetric pattern, SA of one premolar from the normal quadrant into the quadrant missing two premolars with subsequent OSC of the missing sites of the other premolars can be an effective treatment modality.

ABSTRACT To treat morphological abnormalities, impaction, and severe malposition of the teeth, the lateral incisors are sometimes extracted, followed by orthodontic space closure. This procedure often requires special consideration, not only with regard to esthetics but also for functional issues. However, thus far, few reports that have performed a functional evaluation in such cases. The purpose of this article is to report the successful treatment of an adult patient with a Class II division 1 malocclusion who was treated with extraction of the upper lateral incisors. The female patient, aged 23 years and 6 months, had a chief complaint of maxillary incisal protrusion and crooked teeth. In this patient, the upper lateral incisors were extracted to fulfill the patient's strong request, followed by orthodontic treatment using edgewise appliances. A high-pull J-hook headgear on the lower dental arch was used to prevent further labial inclination of the lower incisors. The total active treatment period was 37 months. The resulting occlusion and a satisfactory facial profile were maintained during a 4-year retention period. Additionally, this treatment did not affect the stomatognathic functions as assessed by the following criteria: range of the incisal path or condylar motion during maximal open-close movement, protrusive excursion, lateral excursion, and the chewing test. In conclusion, extraction of the upper lateral incisors can be an effective treatment choice when the upper lateral incisors are dwarfed, are nonvital, or demonstrate severe malposition.

Background: Orthodontic space closure following premolar extraction may result in gingival cleft formation. This may contribute to orthodontic relapse due to reopening of extraction spaces. Purpose: 1) To see the effects gingival clefts have on relapse and opening of closed extraction spaces after orthodontic treatment. 2) To record any changes in cleft severity that may occur. 3) To evaluate any relationship between gingival phenotype and cleft severity. Methods: Subjects recruited from previous study in which gingival clefts were measured during space closure. The clinical measures included the occurrence and severity of clefts and their relationship to gingival phenotype. Results: Sites with a cleft (N=42) had 42.86% relapse and those without (N=19) had 36.84% relapse. Conclusions: As gingival cleft severity increases, the amount of relapse distance is likely to increase. Patients with a thick gingival phenotype who obtain gingival clefts in extraction sites during orthodontic treatment are more likely to have relapse post-treatment compared to sites which did not develop a gingival cleft.

Abstract Aim The aim of this study was to evaluate possible spontaneous space closure after extraction of first permanent molars in children and their eventual need for orthodontic treatment. Methods Twenty-seven children with at least one first permanent molar planned for extraction were enrolled in the study. The children were referred to the Department of Paediatric Dentistry, University of Oslo, between 2009 and 2017. All extracted teeth were severely affected by Molar Incisor Hypomineralisation and/or caries. The children and their parents had consented to extraction and follow-up. Data were analysed with SPSS 26. Results The age of the children was between 5.5 and 12.1 years (mean 8.7) at extraction. The mean follow-up time was 3.2 years (range 1.1–6.3). Sixteen children (59.3%) had all four molars extracted, five (18.5%) had three, five had two and one had one molar extracted. In the maxilla, the second permanent molar had erupted in the place of the first molar in all the children, and none of them needed orthodontic space closure. In the mandible, eight children (29.6%) needed orthodontic treatment to close the spaces after extraction. In three children, the second molar was not yet erupted and treatment need was not settled. Conclusion Extraction of severely affected first permanent molars before the eruption of the second molar is a treatment option causing little additional treatment in the majority of cases.

Abstract Objectives Adults with fixed orthodontic appliances are increasing nowadays. Compared with adolescents, adults present biological differences that might influence treatment duration. Therefore, the aim of the study was to compare duration of treatment with fixed appliances between adults and adolescents. Materials and methods Eight databases were searched up to September 2019 for randomized and non-randomized clinical studies comparing treatment duration with fixed appliances in adolescents and adult patients. After duplicate study selection, data extraction, and risk of bias assessment with the Cochrane ROBINS-I tool, random effects meta-analyses of mean differences (MD) and their 95% confidence intervals (CIs) were performed, followed by assessment of the quality of evidence with GRADE. Results A total of 11 unique studies (one prospective and 10 retrospective non-randomized) with 2969 adolescents and 1380 adult patients were finally included. Meta-analysis of 7 studies found no significant difference in the duration of comprehensive treatment with fixed appliances (MD = − 0.8 month; 95% CI = − 4.2 to 2.6 months; P = 0.65; I2 = 92%) between adults and adolescents. Similarly, both distalization of upper first molars with skeletal anchorage for class II correction and the retraction of canines into the premolar extraction spaces lasted similarly long among adults and adolescents. On the other hand, alignment of palatally displaced canines lasted considerably longer in adults compared to adolescents (1 study; MD = 3.8 months; 95% CI = 1.4 to 6.2 months; P = 0.002). The quality of evidence for the meta-analysis was low due to the inclusion of non-randomized studies with considerable risk of bias. Conclusions While existing evidence does not indicate a difference in the overall duration of treatment with fixed appliances between adults and adolescents, the alignment of palatally displaced canines lasted significantly longer in adults. However, our confidence in these estimates is low due to the risk of bias in the included studies. Trial registration PROSPERO: (CRD42019148169)
