Once defined, this can be broken down into knowledge, skills and attitudes that must be imbibed.The skills must include clinical information gathering, treatment planning and procedures. The trainers must also ask the simple question of the teaching methods to adopt and the assessment tasks to find out whether the residents have achieved the intended outcomes within the context of their future professional role. Once our educational outcomes are clearly specified, then the decisions about teaching methods, course content, educational cum infrastructural environment,and assessment procedures are made in the context of these learning outcomes. According to Chadwick in 2004, 'the ability to reflect on our own actions, articulate what makes a successful performer and the desireto continually improve on that performance is, an essence, what lies at the heart of professionalism itself'. This is food for thought!</p> http://wajo.oauife.edu.ng/index.php/wajo/article/view/81 Experiences, Expectations, Attitudes and Perception of Orthodontic Residents Towards Orthodontic Training Programme in Nigeria 2020-10-09T14:41:27+01:00 B.A Adesina wajo@gmail.com E.T Adebayo wajo@gmail.com <p>Background: The practice of orthodontics in Nigeria has witnessed gradual but steady development since its introduction over three decades ago. Despite significant increase in the number of orthodontic training institutions in Nigeria, there are relatively few orthodontists and even orthodontic residents in training for the population. This is to evaluate the experiences, expectations, attitudes and perception of Nigeria orthodontic residents towards their training.<br>Methods: This was a cross-sectional study conducted among Orthodontics residents at all the accredited Nigerian teaching hospitals. The instrument used was a self- administered, closed anonymous 46-items questionnaire. Data from the questionnaires were collated and entered into Microsoft Excel version 10, 2002 (Microsoft, Redmond, WA, USA) and processed using STATA software (StataCorp LLC, Texas, USA). Fischer's exact test was done where necessary. Statistical significance was set at p?0.05 and tests were two- sided.<br>Results: Out of 41 orthodontic residents in 9 accredited training institutions in Nigeria, 34 participated in the study, representing 82.9%. Most residents (79.4%) chose orthodontics because of the quest for knowledge while a few (2.9%) were mentor guided. Majority (41.2% and 44.1 %) expressed low level of satisfaction with the quality of residency training and the didactic teaching in the program respectively.<br>Conclusion: The study concluded that most of the identified factors affecting orthodontics residency training program in Nigeria are trainee, trainer and curriculum related and will require the dental faculty of the postgraduate colleges to proffer solutions.</p> 2020-10-09T00:00:00+01:00 Copyright (c) 2017 West African Journal of Orthodontics http://wajo.oauife.edu.ng/index.php/wajo/article/view/82 An Assessment of Awareness of Medical Doctors to Malocclusion and Orthodontic Services in a Nigerian Teaching Hospital. 2020-10-09T14:52:01+01:00 T.E Adeyemi wajo@gmail.com O.D. Otuyemi wajo@gmail.com C.O. Oguchi wajo@gmail.com <p>Background: The general health and well-being of individuals can be affected by the state of their oral health. Medical doctors may play an important role in early detection of orthodontic problems in critical areas including timely referral of malocclusion, thus preventing complications. This study assessed the level of awareness of medical doctors concerning malocclusion, orthodontic practitioners and orthodontic treatment services.<br>Methods: This cross-sectional study was conducted among 85 medical doctors in Aminu Kano Teaching Hospital, Kano (AKTH). Self-<br>administered questionnaires were developed and distributed for data collection while statistical Software Package for Social Sciences<br>(SPSS version 20) -Chicago was used for analysis. Statistical significance was set at p&lt;0.05.<br>Results: The sample population consisted of 83.5% male doctors and 16.5% female doctors with a mean age of 34.5±6.4years. Although, many of the doctors did not know that lip-sucking (61.2%) and thumb-sucking habit (48.2%) could adversely affect the front teeth alignment, most of them demonstrated good awareness concerning the orthodontic practitioners. Majority (69.4%) of the doctors were aware that orthodontic treatment services were being carried out in AKTH. Most male doctors did not know that the duration for orthodontic treatment was longer than most other dental procedures and this was statistically significant (p=0.025).<br>Conclusion: Majority of the doctors were aware of availability of orthodontists personnel and orthodontic services in AKTH.<br>However, more male doctors had adequate knowledge of the features of malocclusion whereas their female counterparts were more informed about the duration of orthodontic treatment (p&lt;0.05).</p> 2017-06-01T00:00:00+01:00 Copyright (c) 2017 West African Journal of Orthodontics http://wajo.oauife.edu.ng/index.php/wajo/article/view/85 Occlusal Characteristics of Orthodontic Patients Seen at a Tertiary Health Facility in Bamako, Mali. 2020-10-09T14:59:27+01:00 K.O Touré wajo@gmail.com B.

We evaluated the occlusion of patients receiving treatment at the University Hospital Center, National Center of Odonto-stomatology in Bamako. We observed the various orthodontic abnormalities in patients received at the Orthodontic department.<br>Results: The total study population comprised 432 patients, with 81% having Class I malocclusion, 6.9% in class<br>II division 1, 4.2% in class II division 2 and 7.9% in class III. In addition, 53.7% with maxillary protrusion and<br>55.6% spacing. Dental abnormalities were in lower proportions (less than 7%).<br>Conclusion: Dento-alveolar disproportion in form of spacing, was the main anomaly observed in the population surveyed, whether or not associated with other anomalies An epidemiological study is recommended to determine the prevalence of orthodontic malocclusions in the Malian population.</p> 2017-06-01T00:00:00+01:00 Copyright (c) 2017 West African Journal of Orthodontics http://wajo.oauife.edu.ng/index.php/wajo/article/view/86 Frequency and Pattern of Orthodontic Extractions: A 5 Year Review. 2020-10-09T15:12:25+01:00 O.O. daCosta wajo@gmail.com O.D. Umeh wajo@gmail.com O. Obilade wajo@gmail.com <p>Background: Orthodontic tooth extraction is defined as the removal of one or more permanent teeth excluding the third molars in the course of corrective orthodontics. The frequency of extraction has changed over the years with the evolution of new treatment mechanics. Aim: To determine the frequency and pattern of orthodontic extraction among orthodontic patients.<br>Methods: This was a retrospective descriptive study and the study sample comprised of 237 patients who had undergone or were undergoing orthodontic treatment in the Orthodontic Clinic of the Lagos University Teaching Hospital Idi-Araba Lagos Nigeria over a 5 year period. All relevant information required was obtained from the case file of these patients. Basic descriptive statistics, Chi-Square and Student's t-test were used for data analysis. Level of significance was set at P&lt; 0.05.<br>Results<br>A total of 237 orthodontic patients were recruited for the study; 78 males and 159 females. Angle's Class I malocclusion was the predominant molar relationship. An extraction prevalence of 53.2% was observed with a total of 340 permanent and 44 primary teeth extracted. The upper first premolar was the most frequently extracted tooth, accounting for 72.9% of all permanent teeth extracted (248 teeth), while the primary canine was the most frequently extracted primary tooth. The most common extraction pattern observed in this study was the extraction of all first premolars (28.6%), followed by the extraction of upper first premolars (16.7%). There was no statistically significant difference in the extraction prevalence between males and females (P=0.5).<br>Conclusion: There was high extraction prevalence in the current study when compared to the Caucasian studies, with the first premolars<br>being the most frequently extracted tooth.</p> 2020-10-09T00:00:00+01:00 Copyright (c) 2017 West African Journal of Orthodontics http://wajo.oauife.edu.ng/index.php/wajo/article/view/88 Comparison of Shear Bond Strength of an Orthodontic Adhesive with a Restorative Adhesive 2020-10-09T15:17:30+01:00 F.

Osafo wajo@gmail.com <p>Background: Bonding of orthodontic brackets to enamel surface using composite resins is a significant improvement in clinical orthodontics. Bond strength tests are categorized as tensile or shear bond strength. The objective of the study was to determine and compare shear bond strength of orthodontic adhesive with a proposed restorative adhesive.<br>Methods: Eighty extracted human premolar teeth from patients seeking orthodontic treatment were used. Teeth were divided into four major groups consisting of 1st and 2nd upper and lower premolar teeth. Enamel surface of each tooth was etched and bonded with the brackets using orthodontic and restorative adhesives and a light emitting diode device. Shear bond strength of adhesives were measured using MARK-10 testing machine. Adhesive remnant index (ARI) scores were also determined.<br>Mean bond strength values between groups of teeth were analyzed using One-way analysis of variance (ANOVA) and ARI data analysed using Chi square test.<br>Results: Shear bond strength values for 1st and 2nd of lower premolar teeth bonded with Resilience were 5.96 and 5.75MPa respectively. The<br>values for DenFil adhesive were 5.66 and 7.09 MPa respectively. Shear bond strength values for 1st and 2nd upper premolar teeth for Resilience were 6.22 and 7.67 MPa. For DenFil the values were 7.14 and 7.57MPa. There were no significant differences (p&gt;0.05) in the shear bond strength values of all groups of teeth for both adhesives.<br>Conclusion: Shear bond strength values of DenFil were comparable to Resilience. DenFil may be clinically acceptable as an orthodontic<br>adhesive.</p> 2017-06-01T00:00:00+01:00 Copyright (c) 2017 West African Journal of Orthodontics
