Background: Accelerated orthodontic teeth movement are procedures carried out to increase the rate of tooth movement thereby reducing treatment time. There are numerous techniques currently available to accelerate orthodontic treatment time, but evidence is still needed to determine the degree to which orthodontists accept and practice accelerated orthodontics. The present study is aimed at assessing the knowledge of Orthodontists on the practice of accelerated orthodontics; as well as their willingness to adopt it as a treatment option for their patients., Methodology: Ethical approval was obtained before the commencement of the study. The study population comprised all orthodontists practicing in Nigeria. Questionnaires were administered physically to the orthodontists at their annual general meeting. E-mails were further used to distribute the questionnaire to the orthodontists who were absent from the annual meeting. The questionnaire obtained information on respondents' biodata, knowledge, attitude, and practice of accelerated orthodontic treatment procedures.Statistical analysis was performed using IBM SPSS software version 27. The level of significance was 0.05 for all statistical analysis., Results: The study participants comprised 60 respondents, with a mean age of 34.18 years and a male-to-female ratio of 1.3:1. A Majority of them were satisfied with treatment time/duration (61.7%), they had a good knowledge of accelerated orthodontics (83.3%) with piezocision (75%) and micro-osteoperforation (63.3%) being the most popular. All orthodontists were interested in accelerated orthodontics, if it offered up to 30% reduction in treatment time. Major limitations to the practice included unavailability of technique materials (50%), insufficient knowledge (41.7%) and cost (35%)., Conclusion: Most orthodontists did not routinely practice accelerated orthodontics despite adequate knowledge. They were willing to offer accelerated orthodontic treatment (AOT) if patients were willing to pay an additional fee. The less invasive methods were more accepted., Competing Interests: The Authors declare that no competing interest exists, (Copyright © 2024 by West African Journal of Medicine.)

Objectives: Temporary anchorage devices (TADs) are skeletal anchorage devices. They are minimally invasive and placed by the orthodontist to prevent unwanted tooth movement. This study evaluated the survival rate of orthodontic TADs at 6 months. This study also assessed the effect of age, gender, side, site, dental arch of placement, and length of the TADs on its survival rate., Materials and Methods: Ethical approval was obtained from the Health Research Ethics Committee of the hospital. The study sample comprised orthodontic patients who required the placement of TADs during treatment at a private dental facility in Lagos. Data for the study were obtained from the case files of the study subjects and included the subjects' age, gender, date of placement of the TADs, the site, side and arch of placement, the length of the TADs, and the survival rate of 6 months after placement., Results: We reviewed 90 placed TADs and observed a survival rate of 88.9%. Most TAD failures occurred in the first month of placement ( p = 001). There was no observable statistically significant effect of all other variables assessed (age, gender, arch, site, side, or implant length) on the survival rate of the TADs., Conclusions: The survival rate of TADs was high. Most TAD failures significantly occurred within one month of placement. There was no significant association between all other clinical variables and orthodontic mini-implant survival., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Orthodontic Science.)

Background: The effects of digit sucking on dentofacial structures has been widely studied, but its relationship with the function and/or shape of the palate has been negleted. A clinical observation of high palatal vault has been reportedly associated with digit sucking. However, the description has been made on the basis of subjective clinical observation rather than actual measurements. The aim of this study is to assess the effects of digit sucking habits on palatal dimensions of children with digit sucking habit; and compare the findings obtained to a control population., Method: Cross-sectional sucking behaviour data was collected on 250 school children aged 3 to 5 years using questionnaires completed by parents. Parameters including palatal widths, depth and heights were measured directly from the maxillary casts obtained from the children and palatal index was calculated. All values were compared using t-test., Results: Significant differences were seen in palatal depth, palatal width, palatal height and palatal index at the level of the maxillary primary first and second molars. No significant difference was observed for palatal index at the level of the maxillary primary canine., Conclusions: It was concluded that digit sucking may cause changes in palatal dimensions.

Objectives: The aims of this study were to (1) identify soft tissue cephalometric norms for horizontal lip position in an adult Nigerian population; (2) compare values for Nigerian males and females; and (3) compare Nigerian norms with established norms for Caucasians and other populations., Design: A cross-sectional descriptive study., Setting: Lagos University Teaching Hospital Dental Clinic, Idi-araba, Lagos, Nigeria., Participants: One hundred students (44 males and 56 females) of the College of Medicine, University of Lagos, aged 18-25 years, of Nigerian ancestry, with a normal class I occlusion and no facial asymmetry., Methodology: Lateral cephalometric radiographs of the subjects were taken in natural head position. Radiographs were manually traced and 11 soft tissue cephalometric parameters measured. These were derived from the Steiner, Ricketts, Burstone, Merrifield and Holdaway soft tissue analyses. Male and female values were compared using Student's t-test with a level of significance at P<0·05., Results: Statistically significant differences were observed between Nigerian males and females in eight of the variables studied, with males having more protrusive upper and lower lips than the females. Variables, which did not vary by sex, were soft tissue facial angle, nose prominence and soft tissue chin thickness. In addition, Nigerian norms were higher than norms reported by Steiner, Ricketts, Burstone and Holdaway for Caucasian populations, while the Z-angle was lower than the norm established by Merrifield., Conclusions: Gender-specific soft tissue norms for horizontal lip position should be used for orthodontic treatment planning in Nigerian subjects. Nigerians have more protrusive upper and lower lips compared to Caucasians.

Introduction: The practice of orthodontics is very young in South-South Nigeria and there is need for base line data for informed planning. This study was carried out to investigate the self-perception of malocclusion among Nigerian school children aged 12 to 18 years in order to compare their perception with that of an orthodontist and also to determine the influence of gender and age on self-perception., Materials and Methodology: A total of 612 randomly selected schoolchildren comprising 299 (48.9%) males and 313 (51.1%) females with a mean age of 15 + 2.0 years were included in the study, the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was the instrument used to measure the perception of malocclusion by both the school children and the orthodontist., Results: Majority of the students (82.5%) rated their teeth towards the more attractive end of the scale (Grades 1-4). Although self - perception was not found to be related to gender, older children (16-18 years) had an increased level of perception of need. Males and older children were found to be more in need of treatment by the orthodontist., Conclusions: A significant difference was found between the orthodontist's rating and the students' ratings of the attractiveness of their occlusions. Age and gender were not found to influence self- perceived orthodontic treatment need. Therefore, for effective orthodontic care, self- perception and not only professional assessment must be taken into consideration when formulating treatment plans to ensure patient satisfaction.

Aim: To determine the prevalence of oral habits and assess the effects of these habits on the occlusion in a group of Nigerian schoolchildren., Method: A cross-sectional study of 928 children aged 4-15 years from Eti -Osa local government area in Lagos, Nigeria. The sample population was selected from 2 private and 3 public schools., Results: Three hundred and sixteen children (34.1%) of total children examined, exhibited one form of oral habit or another. The most common habit observed was digit sucking which was observed in 17% of the children. Increased overjet was observed in 33% of the habit children. This was significantly higher than findings in children without the habit who recorded an increased overjet of 25.3%. Anterior open bite was observed in 12.5% of habit children and 3.1% of non-habit children. Statistically significant differences in the occurrence of upper incisor proclination, lower incisor retroclination and lip incompetence were also observed occurring more frequently in the oral habit group. Posterior crossbite was observed in 1.9% of the habit group and 1.5% of the non-habit group. This difference was not statistically significant., Conclusion: This study shows an increased prevalence of oral habits when compared to previous studies in this region. Increased overjet and anterior open bite were the most commonly occurring occlusal anomalies associated with oral habits. There is a need to reduce the occurrence of permanent occlusal deformation due to the persistent form of these habits through dental health education among Nigerian children.

One hundred and four sickle cell anaemia patients aged 10-45 years and attending the out patients' clinic of the Lagos University Teaching Hospital as part of a routine check-up were seen. They were in a steady state of health. By means of a structured questionnaire the Biodata of each consecutive eligible patient was obtained and physical examination was carried out. Oral examination was done with emphasis on occlusal variables including Angle's Classification of occlusion, overjet, overbite, tooth: bone ratio, lip competence and skeletal pattern. Results showed that the majority of the patients 92 (88.5%) seen presented with Angle's Class 1 malocclusion. Increased overjet was observed in 50 (48.2%) of the sample population while an overbite depth of 2 was most frequently seen in these patients. Spacing in the anterior segment of the upper and lower arches was a fairly common occurrence, occurring in 51 (49.0%) and 39 (30.8%) of the patients seen respectively. Normal dental base relationship (Skeletal 1) was observed in 72 (69.2%) while lip incompetence was seen in 41 (39.4%) of the patients examined. Occlusal anomalies vary from mild to severe and may be attributable to hyperplastic maxillary bone and the resultant skeletal discrepancy.

An increased prevalence of the digit sucking habit among Nigerian children has been reported. Certain factors are believed to influence its occurrence. This study was carried out to assess these factors and determine possible correlation with the onset and persistence of the habit. The sample population consisted of 81 children--52 females and 29 males aged 3-16 years who were still actively digit sucking. Findings in this group were compared with a control group made up of 80 children aged 2-16 years who were not digit suckers and had no history of the habit. Results showed no correlation between mode of infant feeding and the digit sucking habit. The duration of breast-feeding was found to have a significant effect on the habit. About 79% of non-suckers had been breast-fed for more than 6 months while only 43.2% of digit suckers were breast-fed for the same duration. The digit sucking habit was observed more frequently in children with mothers in high cadre occupations (53.1%) compared to non-suckers (23.8%). More digit suckers (22.2%) than non-suckers (12.5%) were reported to have a history of pacifier use. Neither family size nor position of the child in the family had a significant effect on the occurrence of the habit. In addition, 48.1% of the sample population had siblings with the same habit compared to 16.2% of the controls. The identification of significant factors may be useful in targeting interventions in order to prevent consequences of the prolonged habit.

Digit (thumb or finger) sucking is the most common oral habit, frequently seen among young children. With an increase in the prevalence of the oral habit in Nigeria in recent years there should be an expected increase in the dentofacial effects of the habit. In this study 81 children, 29 males and 52 females aged 3-16 years were examined. Each child was still actively engaged in the digit sucking habit. Subjects were divided into 3 age groups--3-6 years, 7-10 years and 11 years and above. The dentofacial effects of the habit on each subject were assessed. Increased overjet was observed in 63-705 of the children in the different age groups while the occurrence of anterior open bite ranged from 33.3% to 80% declining in frequency with increase in age. Unilateral posterior crossbite was observed in 8.65 of children while no case of bilateral crossbite was observed. Lip incompetence occurred in 51.8% of children examined, occurring most frequently in the oldest age group. Class 2 skeletal pattern was observed in 22.2% of the sample population. Results show that malocclusion is a frequent result of digit sucking especially when prolonged. There is a need to increase social awareness of the detrimental effects of this habit and if necessary offer alternative non-nutritive sucking methods.

An epidemiological survey of 1,028 children, 544 females (52.9%) and 484 males (47.1%) was carried out in Kaduna Nigeria to assess the prevalence of malocclusion in the Northern part of Nigeria. The sample population aged 11-18 years were of Northern Nigeria origin and none had received previous orthodontic treatment. From the results, normal occlusion was seen in 12.2% children, Angle's Class I malocclusion in 84.0%, 1.7% had Angle's Class II while Angle's III was observed in 2.0%. No case of Angle's Class II div 2 was seen. A reduction in the prevalence of Angle's Class II div I was seen to occur with increasing age while an increase in Angle's III malocclusion was noted in the 17-18 years age group. Spacing of the upper anterior segment was observed to occur in 45.9% of children examined while spacing of the lower anterior segment was seen in 30%. Crowding of these segments occurred in 21.6% and 36.3% respectively of the sample population. Using Jackson's method (1962) Overbite I was found to occur in 69.5% of the children examined. Deep bite (Overbite 3) occurred in only 1.6% of those examined. An overjet values of 2-4 mm was the most prevalent occurring in 70.8% of the children. A low prevalence of bimaxilliary proclination was observed (3.7%).
