A qualitative analysis on participants' perspectives on oral implants.

BACKGROUND: Quantitative research methods provide clinicians with information about the effectiveness of interventions and determined causal-effect relationships, whereas qualitative research investigates other aspects of clinical implant practice, particularly the participants' perspectives and expectations. The aim of the qualitative study was to understand the experience of participants with immediate single molar implants. METHODS: In-depth, audiorecorded, semistructured interviews were conducted with 15 participants who had participated in a controlled clinical trial of immediate molar implants. Participants were aged 36-77 years. Nine participants received single implants in mandibular molar fresh extraction sockets while the remaining participants had their implants in healed sites. The interviews that assessed participants' perspectives of the pre-operative, operative, and postoperative phases of therapy were transcribed verbatim and analysed using inductive and content analysis. RESULTS: Participants took part in the clinical trial mainly because it offered oral implant therapy at a reduced cost. The affordability of implant treatment was the main factor in determining restorative options. Minimal differences were found between male and female participants of different age groups in terms of their perceptions of function and aesthetics. However, single molar implants did not have an impact on aesthetics and self-esteem. Participants' expectations regarding the longevity of oral implants were not realistic and their knowledge about future maintenance needs was not adequate. CONCLUSIONS: Using face-to-face verbal conversation more frequently may improve communication between clinicians and participants and minimize misunderstanding about the procedures of different treatment modalities. Special emphasis should be placed on understanding the importance of maintenance by spending more time with the participants to identify any future barriers to maintaining good outcomes of oral implants.

Patients' perspectives on zirconia and titanium implants with a novel distribution supporting maxillary and mandibular overdentures: a qualitative study.

OBJECTIVES: This qualitative study explored the perceptions of edentulous patients regarding their rehabilitation with maxillary and mandibular implant-supported overdentures employing a protocol that featured novel implant sites and distribution. MATERIAL AND METHODS: In-depth semi-structured interviews were conducted with 16 participants who have taken part in a randomized controlled trial. Each received implant overdentures supported by either titanium or zirconia one-piece implants. Participants received four implants in the maxilla and three implants in the mandible. The implant distribution was: in the maxilla, a mid-palatal implant, and three anterior implants in the incisor and first premolar regions; in the mandible, a mid-symphseal implant, and bilateral distal implants in the first molar region. All interviews were conducted by a researcher not involved with the clinical aspect of the randomized controlled trial and were transcribed verbatim and analyzed using a thematic inductive analysis approach. RESULTS: The perceived advantages of the treatment were functional improvement and increased social confidence. Cost was a significant barrier for edentulous patients seeking implant treatment. Previous experience with complete dentures, age and length of treatment was further factors that influenced decisions regarding prosthodontic rehabilitation. The novel implant protocol was acceptable to patients. CONCLUSIONS: Implant overdentures improve the quality of life of edentulous patients. Acceptance of dental implants may be increased by mitigating the cost of treatment. The mid-palatal implant site may be a potential alternative to extensive surgical procedures during the prosthodontic rehabilitation of atrophic maxillary ridges. The mandibular design offers patients the advantages of a removable prosthesis with increased retention.

Adults with intellectual disability: a mixed-methods investigation of their experiences of dental treatment under general anaesthetic.

OBJECTIVES: This study aimed to explore the experiences of dental care under general anaesthesia in adults with an intellectual disability. METHODS: The study used an explanatory mixed-methods design. In the initial quantitative phase of the study, a clinical audit of oral health services provided for adults with intellectual disabilities was carried out for individuals who underwent a general anaesthetic (GA) for dental treatment at Christchurch Hospital during a 5-year period. In a qualitative second phase, fifteen semi-structured interviews were carried out for 13 individuals with an intellectual disability to investigate the experience and perceptions of individuals with an intellectual disability (and caregivers and guardians) relating to their oral health care. RESULTS: The majority of the treated patients lived in care, and many had severe medical problems. Most had both restorative treatment and tooth extractions carried out under GA. Their major concern was anxiety associated with the dental visits. Support people/ guardians shared this concern, and played a vital role in helping to manage this anxiety. Many of the latter had difficulty identifying dental problems in their charges, and they often relied on detection of changes in the individual's behaviour or demeanour. The time spent waiting in waiting rooms for treatment was a frequently reported cause of stress. CONCLUSIONS: As a group, these individuals present challenges for the provision of oral health care, given their severe disability and medical conditions, and many require a high level of support for daily activities. When dental treatment is required, a GA is often necessary in order to carry it out. The management of anxiety was a key issue for the patient group and support people play a vital role in helping to manage this anxiety, and achieve a successful visit. There is potential to improve the service with a multidisciplinary approach to coordinate other health services during treatment episodes, reduced time spent in waiting rooms, and improved waiting room layout.

Reducing disease burden and health inequalities arising from chronic disease among indigenous children: an early childhood caries intervention in Aotearoa/New Zealand.

BACKGROUND: Maaori are the Indigenous people of New Zealand and do not enjoy the same oral health status as the non-Indigenous majority. To overcome oral health disparities, the life course approach affords a valid foundation on which to develop a process that will contribute to the protection of the oral health of young infants. The key to this process is the support that could be provided to the parents or care givers of Maaori infants during the pregnancy of the mother and the early years of the child. This study seeks to determine whether implementing a kaupapa Maaori (Maaori philosophical viewpoint) in an early childhood caries (ECC) intervention reduces dental disease burden among Maaori children. The intervention consists of four approaches to prevent early childhood caries: dental care provided during pregnancy, fluoride varnish application to the teeth of children, motivational interviewing, and anticipatory guidance. METHODS/DESIGN: The participants are Maaori women who are expecting a child and who reside within the Maaori tribal area of Waikato-Tainui.This randomised-control trial will be undertaken utilising the principles of kaupapa Maaori research, which encompasses Maaori leadership, Maaori relationships, Maaori customary practices, etiquette and protocol. Participants will be monitored through clinical and self-reported information collected throughout the ECC intervention. Self-report information will be collected in a baseline questionnaire during pregnancy and when children are aged 24 and 36 months. Clinical oral health data will be collected during standardised examinations at ages 24 and 36 months by calibrated dental professionals. All participants receive the ECC intervention benefits, with the intervention delayed by 24 months for participants who are randomised to the control-delayed arm. DISCUSSION: The development and evaluation of oral health interventions may produce evidence that supports the application of the principles of kaupapa Maaori research in the research processes. This study will assess an ECC intervention which could provide a meaningful approach for Maaori for the protection and maintenance of oral health for Maaori children and their family, thus reducing oral health disparities.

An exploratory study of pregnant women's knowledge of child oral health care in New Zealand.

BACKGROUND: To be maximally effective, oral health preventive strategies should start at birth. There appear to be few reports on pregnant women's knowledge of oral health care for their developing children. OBJECTIVES: This exploratory study assessed Dunedin expectant mothers' knowledge of the oral health care of their future children. METHODS: A questionnaire was developed to assess expectant mothers' knowledge of child oral health and appropriate prevention strategies. Three public Lead Maternity Carer (LMC) organisations and 30 private individual LMCs were asked to distribute the questionnaire to their clients attending appointments during a one-month period. Questions focused on the mother's knowledge of oral health practices for their future children, including oral hygiene and access to dental care. RESULTS: Fewer than half of the participants thought they had enough information about their child's oral health needs. One-quarter thought that toothbrushing should not start until after two years of age. The majority thought their child should not be seen by a dental professional until this age, while one-fifth did not think their child should be seen until four years old. Poorer child oral health knowledge was found in first-time mothers, younger women, those from low-SES groups, and those who were not New Zealand (NZ) Europeans. CONCLUSIONS: A substantial number of participants were unaware of how to provide appropriate oral health care for their children despite the available information. This lack of awareness needs to be taken into account when designing oral health promotion strategies for parents of very young children.

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.

Is New Zealand water fluoridation justified?

Public health programmes extend beyond the clinical context and focus on measures that affect the lives of large subgroups or the population as a whole. An example of this is community water fluoridation (CWF), the altering of fluoride levels in the water supply with the aim of preventing the initiation and slowing the progression of dental caries lesions for the benefit of entire populations. Despite the unfeasibility of randomised controlled trials of CWF, a large volume of evidence is available on the topic. However, CWF remains a polarising and keenly contested issue. CWF is also an intervention where it is difficult to provide everyone affected with a choice. The Nuffield Council on Bioethics is an independent body that examines and reports on ethical questions, and they have provided a useful ethical framework for considering CWF via the 'stewardship' model. This commentary aims to discuss each of the public health aims and how they can be applied and weighed to reach a justified position about CWF.
