A systematic sample of 1010 cases was collected by the Dental Practice Board. The commonest type of treatment involved extraction of the first premolars followed by removable appliances. Treatment duration was on average 1·9 years, one-arch fixed appliances were started in an older age group and two-arch fixed appliance treatment took longer to complete than other appliance types. The best standard of treatment was achieved using upper and lower fixed appliances.

Relevant features of a sample of discontinued treatments were investigated, including status at the start and at the time of discontinuation. In a comparison between two discontinued groups, those patients who simply failed to return tended to have lower pretreatment PAR scores, and were more likely to have received non-extraction treatments in which removable appliances were employed. However, when discontinued treatments were compared to completed treatments undertaken in 1987/8, the completed cases were only reduced by two further PAR points.

OBJECTIVES: To determine the frequency of emergencies in patients with fixed and removable orthodontic appliances at tertiary care dental hospital. METHODOLOGY: A questionnaire was designed for this descriptive cross-sectional study to be filled by the clinician (L3/L4 FCPS resident) at the end of addressing every orthodontic emergency. Sampling was done under consecutive non-probability protocols. Descriptive statistics were applied to determine the frequency of different orthodontic emergencies, and Pearson’s chi-square test was applied to determine association of emergencies with gender and etiology of emergency (patient related vs operator related). Data was analyzed on SPSS version 20. RESULTS: A total of 175 patients reported with orthodontic emergencies. The sample comprised 38.3% males and 61.7% females. Most frequent orthodontic emergency reported was deboned brackets in fixed appliances, while the most common emergency in removable appliances was traumatic PNAM. A statistically significant association (Pearson’s Chi Square=4.74, Cramer’s V=0.165, p=0.029) was seen for removable and fixed appliance emergencies with males and females. CONCLUSION: Most frequent fixed appliance orthodontic emergencies were deboned brackets while for removable appliance emergencies were trauma due to PNAM. Emergencies with removable appliances were mostly due to the operator related factors, while in fixed appliances patient related factors were dominating.

Quad Helix

Combination quad helix and bite riser posterior for anterior crossbite treatment. Anterior crossbite treatment can be done with the appliances either by removable appliances or fixed appliances. One fixed appliance that can be used in the treatment of anterior crossbite is a quad helix with a combination of bite raiser posterior. It is the preferred appliance for correction of maxillary dental constriction in a preadolescent child. Quad helix is activated by widening the anterior or posterior helices. An 11-year-old female patient referred to the clinic with a problem of crowding teeth that affected her appearance. The diagnosis for her case was malocclusions dentoalveolar class I angle along with anterior crossbite 12 and 21, anterior crowding maxilla with convex face profile, shifted median line, and no TMJ disorder. The treatment plan used a quad helix and bite riser posterior followed by a fixed orthodontic treatment. The aim of this study was to correct the anterior crossbite using a combination of a quad helix and bite raiser posterior. The patient was treated using composite bite raiser posterior on the occlusal surface of 16.26, and quad helix soldered to bands and cemented on 16 and 26. The patient was instructed to get her teeth controlled every two week to activate quad helix. After 3 months of active treatment, anterior crossbite was corrected. The appliance was left passively in place for 3 months as retention. The study concluded that crossbite treatment with a combination of a quad helix and bite riser was effective in correcting anterior crossbite in adolescents.ABSTRAKPerawatan crossbite anterior dapat dilakukan dengan beberapa macam alat baik dengan alat lepasan ataupun alat cekat. Salah satu alat semi cekat yang dapat digunakan pada perawatan crossbite anterior adalah quad helix dengan kombinasi tanggul gigitan posterior. Quad helix merupakan alat yang dapat digunakan untuk konstriksi dental di maksila pada masa remaja. Seorang pasien anak perempuan berusia 11 tahun mengeluhkan keadaan giginya yang berjejal dan menganggu penampilannya. Diagnosis kasus adalah maloklusi dentoalveolar kelas I angle disertai crossbite gigi 12 dan 21, crowding anterior rahang atas dengan profil muka cembung, garis median tidak sesuai dan tidak disertai gangguan TMJ. Rencana perawatan menggunakan quad helix dan tanggul gigitan posterior kemudian dilanjutkan dengan perawatan ortodontik cekat. Tujuan artikel ini adalah menyajikan perawatan crossbite anterior dengan menggunakan kombinasi quad helix dan tanggul gigitan posterior. Pasien dirawat menggunakan tanggul gigitan komposit posterior pada permukaan oklusal gigi 16, 26 dan quad helix yang disolder pada molar band dan disementasi di molar band pada gigi 16 dan 26 kemudian pasien diinstruksikan untuk kontrol setiap dua minggu satu kali kunjungan untuk aktivasi quad helix. Setelah perawatan aktif 3 bulan crossbite anterior telah terkoreksi. Alat ditinggalkan di dalam mulut dalam keadaan pasif selama 3 bulan sebagai retensi. Dapat ditarik kesimpulan bahwa perawatan crossbite dengan kombinasi quad helix dan tanggul gigitan posterior efektif dalam mengoreksi  crossbite anterior pada remaja.

Fifty consecutive treatment case records were analysed for each of the years 1964, 1971, 1974, 1976 and 1978. The following variables were examined: sex distribution, age at start of treatment, extractions undertaken (if any), type of appliance used, completeness or incompleteness of treatment, treatment duration and one final category termed ‘other clinical procedures’ dealing with cephalometry, photography and surgery. The sex distribution fluctuated only slightly with a predominance of females throughout. The age of onset of treatment was fairly constant at around 12 years. Over the 15 years a rise in the number of non-extraction cases was noted and the number of patients treated by extraction only, fell. The use of fixed appliances increased steadily and in 1978 55 per cent of cases received some form of fixed appliance therapy. The mean number of incomplete cases was 17 per cent for all years with no rise latterly despite the use of more complex appliances. The treatment duration time showed a steady decrease over the 15 year period. Few referrals for oral surgery were made, although the use of pericision following rotation correction has increased.

ABSTRACT Objective:  To compare patients’ perceptions of fixed and removable appliance therapy for correction of anterior crossbite in the mixed dentition, with special reference to perceived pain, discomfort, and impairment of jaw function. Material and Methods:  Sixty-two patients with anterior crossbite and functional shift were recruited consecutively and randomized for treatment with fixed appliances (brackets and archwires) or removable appliances (acrylic plates and protruding springs). A questionnaire, previously found to be valid and reliable, was used for evaluation at the following time points: before appliance insertion, on the evening of the day of insertion, every day/evening for 7 days after insertion, and at the first and second scheduled appointments (after 4 and 8 weeks, respectively). Results:  Pain and discomfort intensity were higher for the first 3 days for the fixed appliance. Pain and discomfort scores overall peaked on day 2. Adverse effects on school and leisure activities were reported more frequently in the removable than in the fixed appliance group. The fixed appliance group reported more difficulty eating different kinds of hard and soft food, while the removable appliance group experienced more speech difficulties. No significant intergroup difference was found for self-estimated disturbance of appearance between the appliances. Conclusions:  The general levels of pain and discomfort were low to moderate in both groups. There were some statistically significant differences between the groups, but these were only minor and with minor clinical relevance. As both appliances were generally well accepted by the patients, either fixed or removable appliance therapy can be recommended.

The Four Thames Project to develop training in orthodontics for dental practice, offered 26 clinical attachments with Consultants, over a 2-year period (October 1984–1986). A course of tuition was provided centrally in four modules. The programme was evaluated using a postal questionnaire and personal interview of the course participants, and with a postal questionnaire of the participating Consultants. The results of the evaluation are discussed an effects on the orthodontics in the participants' practices and consultants' units are outlined. Those on the first 2-year programme changed the range of their orthodontic practice to include more use of fixed appliances and a reduction in the use of removable appliances and of treatment by extraction and observation alone.

Abstract Objectives Cervical component of thymus is noted more in children and young adults than in older age group. CT texture (lobules of soft tissue interspersed with fat), similarity with CT density of mediastinal thymus and continuity with mediastinal thymus on sagittal/coronal images, are given as the criteria for diagnosis of the cervical thymus. But CT densities of cervical and mediastinal components of the thymus may vary. The purpose of our study was to compare CT densities of cervical and mediastinal parts of the thymus, in cases where ultrasonography correlation was available. Methods We retrospectively identified 22 patients who had undergone CT between May 2015 and May 2017 and in whom ultrasonography (USG) correlation was available. CT densities of cervical and mediastinal components of thymus were measured. Results CT density of cervical thymus is lower than the CT density of mediastinal thymus by ~ 25 HU. There is a moderate positive correlation between CT densities of cervical and mediastinal parts of the thymus. CT densities of both cervical and mediastinal thymus were found to reduce with age, but the reduction was statistically significant only in the cervical thymus in this study. Conclusions CT densities of cervical and mediastinal components of the thymus may vary, with CT density of cervical thymus being lower. There is a positive correlation between CT densities of cervical and mediastinal parts of the thymus. CT density of cervical thymus reduces with age. Understanding these may help avoid confusion on CT and avoid the need for correlative USG, saving time and effort.

Abstract Background Coronavirus disease (COVID-19) is a respiratory syndrome with a variable degree of severity. Imaging is a vital component of disease monitoring and follow-up in coronavirus pulmonary syndromes. The study of temporal changes of CT findings of COVID-19 pneumonia can help in better understanding of disease pathogenesis and prediction of disease prognosis. In this study, we aim to determine the typical and atypical CT imaging features of COVID-19 and discuss the association of typical CT imaging features with the duration of the presenting complaint and patients’ age. Results The lesions showed unilateral distribution in 20% of cases and bilateral distribution in 80% of cases. The lesions involved the lower lung lobes in 30% of cases and showed diffuse involvement in 58.2% of cases. The lesions showed peripheral distribution in 74.5% of cases. The most common pattern was multifocal ground glass opacity found in 72.7% of cases. Atypical features like cavitation and pleural effusion can occur early in the disease course. There was significant association between increased number of the lesions, bilaterality, diffuse pattern of lung involvement and older age group (≥ 50 years old) and increased duration of presenting complaint (≥ 4 days). There was significant association between crazy-paving pattern and increased duration of presenting complaint. No significant association could be detected between any CT pattern and increased patient age. Conclusion The most common CT feature of COVID-19 was multifocal ground glass opacity. Atypical features like cavitation and pleural effusion can occur early in the course of the disease. Our cases showed more extensive lesions with bilateral and diffuse patterns of distribution in the older age group and with increased duration of presenting complaint. There was a significant association between crazy-paving pattern and increased duration of presenting complaint. No significant association could be detected between any CT pattern and increased patient age.

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)
