A qualitative investigation of specialist orthodontists in New Zealand: part 2. Orthodontists' working lives and work-life balance.

BACKGROUND: Orthodontics is the most widely practised form of specialist dentistry in New Zealand. To date, no known qualitative research has been published examining the work-life balance of practitioners. The aim of this study was to investigate the working lives and work-life balance of NZ orthodontists in order to generate an understanding of the reality of orthodontic specialist practice and its effects on orthodontists' professional and personal lives. METHODS: Semi-structured interviews were conducted involving 19 practising orthodontists (four females, 15 males; mean age 50 years) from throughout New Zealand and selected for maximum variation in the sample. Transcribed interviews were analysed for themes using an applied grounded theory approach. RESULTS: A core category of 'practising orthodontist' was derived, and related themes were grouped under the sub-categories of: (a) NZ orthodontic specialist practice; (b) NZ specialist orthodontists; and (c) Work-life balance. The present paper reports on the final sub-category. Themes emerging from the work-life sub-category were further divided into two sub-themes of 'work' and 'life'. Themes in the 'work' subgroup included time off, injuries and illness, regrets, personality traits, job stress and criticism, establishing a practice, peer support and contact, and success in orthodontics. Themes in the 'life' sub-group were personal development, family life, life balance and interests outside work, and financial security. CONCLUSIONS: This was the first qualitative investigation of the orthodontic profession in New Zealand. The findings provided a valuable insight into the working lives of New Zealand orthodontists and effects on their day-today lives. It will be revealing and interesting to observe how the modernisation of orthodontic practice will affect the work-life balance of New Zealand orthodontists in the future.

A qualitative investigation of specialist orthodontists in New Zealand. Part 1. Orthodontists and orthodontic practice.

BACKGROUND: Current knowledge of orthodontic practice is largely anecdotal and the lack of systematic knowledge can create barriers to better identifying the factors that make a successful orthodontist. The aim of this study was to investigate the routine practising lives of New Zealand orthodontists in order to generate an understanding of the reality of orthodontic specialist practice and its effects on their professional and personal lives. METHODS: Semi-structured interviews were conducted involving 19 practising orthodontists (four females, 15 males; mean age 50 years) throughout New Zealand.Transcribed interviews were analysed for themes using an applied grounded theory approach. RESULTS: A core category of 'practising orthodontists' was derived, and related themes were grouped under the sub-categories of: (a) NZ orthodontic specialist practice; (b) NZ specialist orthodontists; and (c) work-life balance. The present paper reports on the first two subcategories. Themes elucidated under the specialist practice sub-category included modernisation, changing social norms, practice arrangement, branch practice, staffing, competition, legislation, advertising, the future and the provision of orthodontics by non-specialists. Themes in the orthodontic specialist sub-category were prior experience, postgraduate training, recent graduates, reasons for specialising, generational differences, females in orthodontics, NZ and overseas practice, the ageing profession and the prospect of an orthodontist shortage. CONCLUSIONS: This investigation has shed light on orthodontists and the practice of orthodontics in New Zealand and determined aspects rarely discussed in the current or previous literature. It will be valuable to observe how orthodontists and orthodontic practice continue to evolve in response to changes in NZ society.

Factors influencing treatment time in orthodontic patients.

INTRODUCTION: The purpose of this retrospective study was to identify (and quantify the effect of) factors that influence orthodontic treatment time. METHOD: The sample consisted of 366 consecutive orthodontic patients (220 female, 146 male, aged 10-20 years, treated by 1 orthodontist) who completed treatment in a single stage with fixed appliances. Four categories of data (sociodemographic characteristics, malocclusion characteristics, treatment methods, and patient cooperation) were collected from treatment records and analyzed. RESULTS: Average treatment time was 23.5 months (range, 12-37; SD, 4.7). A multiple regression model explained 38% of the variance and identified 9 significant variables. Five were pretreatment characteristics: male sex, maxillary crowding of 3 mm or more, Class II molar relationships, proposed treatment plan involving extractions, and delayed extractions. The remaining variables (3 of which were associated with patient cooperation) were poor oral hygiene, poor elastic wear, bracket breakages, and brackets rebonded for repositioning. CONCLUSIONS: Orthodontic treatment time is influenced by a number of patient characteristics and clinical decisions. It is possible to predict estimated treatment time for a patient by using a small number of personal characteristics and treatment decisions.

Amelogenesis imperfecta--multidisciplinary management from eruption to adulthood. Review and case report.

Amelogenesis imperfecta (AI) is a group of hereditary conditions that affect enamel formation. It is associated with a high morbidity for the patients and may present major restorative and sometimes orthodontic challenges for the dental team. Early recognition followed by appropriate preventive and restorative care is essential in the successful management of AI. A multidisciplinary approach with careful planning from early childhood will maximise the treatment options available for the permanent dentition and optimise the final outcome. In this case, a team consisting of two paediatric dentists, an orthodontist, a restorative dentist, and an oral and maxillofacial surgeon were involved in the management of the patient over a 12-year period. Treatment included preventive advice, interim composite restorations, two phases of orthodontic treatment, orthognathic surgery and placement of cast crowns. The patient is extremely happy with the result.
