Artificial intelligence in orthodontics and orthognathic surgery: a bibliometric analysis of the 100 most-cited articles.

BACKGROUND: The application of artificial intelligence (AI) in orthodontics and orthognathic surgery has gained significant attention in recent years. However, there is a lack of bibliometric reports that analyze the academic literature in this field to identify publishing and citation trends. By conducting an analysis of the top 100 most-cited articles on AI in orthodontics and orthognathic surgery, we aim to unveil popular research topics, key authors, institutions, countries, and journals in this area. METHODS: A comprehensive search was conducted in the Web of Science (WOS) electronic database to identify the top 100 most-cited articles on AI in orthodontics and orthognathic surgery. Publication and citation data were obtained and further analyzed and visualized using R Biblioshiny. The key domains of the 100 articles were also identified. RESULTS: The top 100 most-cited articles were published between 2005 and 2022, contributed by 458 authors, with an average citation count of 22.09. South Korea emerged as the leading contributor with the highest number of publications (28) and citations (595), followed by China (16, 373), and the United States (7, 248). Notably, six South Korean authors ranked among the top 10 contributors, and three South Korean institutions were listed as the most productive. International collaborations were predominantly observed between the United States, China, and South Korea. The main domains of the articles focused on automated imaging assessment (42%), aiding diagnosis and treatment planning (34%), and the assessment of growth and development (10%). Besides, a positive correlation was observed between the testing sample size and citation counts (P = 0.010), as well as between the time of publication and citation counts (P < 0.001). CONCLUSIONS: The utilization of AI in orthodontics and orthognathic surgery has shown remarkable progress, particularly in the domains of imaging analysis, diagnosis and treatment planning, and growth and development assessment. This bibliometric analysis provides valuable insights into the top-cited articles and the trends of AI research in this field.

Self-designed three-dimensional printed skeletal anchorage titanium device for orthopaedic traction in a growing Class III patient.

Maxillary retrusion in a growing skeletal class III patient can be treated with growth modification by facemask therapy with skeletal anchorage. A 12-year-old boy presented with Skeletal Class III relationship, retrognathic maxilla and paranasal deficiency. Cone beam computer tomography (CBCT) was taken for the design of the customized skeletal anchorage device with a 3D planning computer software. Two pairs of skeletal anchorage surgical guides and plates were designed with the correct vector and location, and to avoid tooth roots in the fixation. The plates were printed with titanium and fixed onto the patient for the facemask therapy. CAD-CAM technology allows customization and precise execution of the skeletal anchorage for the facemask therapy. Self-designed 3D printed skeletal anchorage device, with the advantages of increased rigidity, ease of placement and accuracy of force application, can be a valid alternative to stock titanium plates.

Effects of Two-Phase Treatment with Functional Appliances Followed by Extraction versus One-Phase Treatment with Extraction in Class II Growing Patients: A Case-Control Study.

Objectives: Fixed appliance treatment with premolar extraction is often required after functional appliance treatment to relieve crowding and improve facial aesthetics in the Asian population. This study compared the treatment efficacy of two approaches for treating Class II division 1 malocclusion: functional appliance followed by fixed appliance treatment with extraction (two-phase) and fixed appliance treatment with extraction (one-phase). Methods: Growing skeletal Class II patients with an overjet of ≥6 mm treated with two- or one-phase orthodontics were included. The two groups consisted of 29 patients (mean age = 12.55) and 30 patients (mean age = 12.72), respectively. Pre- and post-treatment cephalograms were analysed and skeletal, dental, and soft tissue characteristics were compared using independent t-tests. Treatment changes were compared within and between groups using paired and independent t-tests, respectively. Stepwise discriminant analysis was performed to identify the variables that best predicted pre-treatment group allocations. Results: At baseline, there were no significant between-group differences in age, gender, cervical vertebral maturation, or overjet. The two-phase group had greater Class II skeletal discrepancies (ANB angle and Wits appraisal). During treatment, the two-phase group showed greater improvements in intermaxillary relationship and facial convexity compared with the one-phase group (p < 0.01). Following treatment, the two-phase group had a greater L1/APog distance (p < 0.05). Facial convexity and Wits appraisal were identified as parameters significantly influencing the clinicians' decision to use a one- or two-phase approach. Conclusions: In patients requiring premolar extraction, two-phase (vs. one-phase) treatment produced greater improvements in the intermaxillary relationship and facial convexity.

Job stress among nurses in China.

Job stress is a well-known situation for nurses, especially for those working in the clinical environment. The purpose of this descriptive study was to examine the job stress level and stressors among nurses in a Zhuhai hospital. Ninety-three nurses were recruited for the study. Findings were that nurses had a relatively high level of stress, with "Working Environment and Resources" and "Workload and Time" identified as the major stressors. This study provided preliminary insights on relieving job stress among nurses in China.

Using the Roy adaptation model to develop an antenatal assessment instrument.

The utility of a nursing model as a framework to understand and explain a health phenomenon is fundamental to guide nursing practice. In this article, the authors aim to provide an examination of the Roy adaptation model as a basis for the development of an instrument used for assessing the health needs of pregnant women. With the congruence between the concepts in the Roy adaptation model and antenatal practice, an antenatal assessment instrument is developed. The assessment areas focus on pregnant women's behaviors in the four adaptation modes. The current experience is valuable for nurses who are involved in instrument development and midwifery practice.

Nurses' experiences in spirituality and spiritual care in Hong Kong.

Nurses emphasize spiritual care in maintaining patients' holistic health; however, the provision for spiritual care is found to be inadequate. The limited study in exploring the nurses' perception on applying spiritual care in Hong Kong has been noted. This descriptive phenomenological study investigated the experiences of spirituality and spiritual care in Hong Kong from the nurses' perspective. Ten nurses were purposively invited for an unstructured interview. Thematic analysis was used for data analysis, and three themes emerged: the meaning of spirituality, benefits of applying spiritual care, and difficulties in applying spiritual care. This study provided preliminary insights into the development of spiritual care in Hong Kong.

Upper gastrointestinal problems in inhalational ketamine abusers.

OBJECTIVE: To study the association between upper gastrointestinal (GI) problems and inhalational ketamine abuse. METHODS: This is a retrospective study of 64 ketamine abusers treated from 2001 to 2008. Variables studied included clinical presentations, findings of upper GI endoscopy, abstinence from ketamine and relief of epigastric pain. RESULTS: The following patients with (i) a previous history of upper GI problem; (ii) a history of non-steroidal anti-inflammatory drug (NSAID), aspirin or other substance abuse; and (iii) a known history of Helicobacter pylori (H. pylori) infection were excluded. The study group thus consisted of 37 ketamine abusers, of whom 28 had upper GI symptoms. Overall 14 of these patients had an upper endoscopy performed. The endoscopic diagnoses were: 12 (85.7%) with gastritis, one (7.1%) with gastroduodenitis, and one (7.1%) normal finding. Test for H. pylori, infection was negative. Abstinence from ketamine was found to be associated significantly with relief of symptoms (P= 0.027). Logistic regression showed the odds ratio of symptomatic relief for abstinence versus continued use of ketamine is 12.5 (95% CI[1.20, 130.6], P= 0.035). In patients whom an upper GI endoscopy was performed, H. pylori negative gastritis was the commonest histopathological finding (78.6%). Despite the use of medications, symptoms are commonly not relieved and that is associated with the continued abuse of ketamine. CONCLUSION: Ketamine abusers frequently presented with upper GI symptoms, the commonest of which is epigastric pain (73% of abusers). Abstinence from ketamine abuse can lead to the relief of symptoms, which is an important message for ketamine abusers.

A family psychoeducation group program for chinese people with schizophrenia in Hong Kong.

OBJECTIVES: This study tested the effectiveness of a family psychoeducation group program over a 12-month period for families of Chinese patients in Hong Kong with schizophrenia. The psychoeducation program is a needs-based group intervention that addresses the perceptions, knowledge, and skills of families in caring for relatives with schizophrenia. METHODS: A controlled trial was conducted with 84 family members. Patient and family variables were measured at recruitment and at one week and 12 months after completion of the intervention. RESULTS: Multivariate analyses of variance showed that participants in the psychoeducation group reported greater improvements in families' and patients' functioning, families' burden of care, and the number and length of patients' rehospitalizations over the 12-month follow-up period, compared with the standard care group. CONCLUSIONS: These findings support the effectiveness of the family psychoeducation group program in improving the psychosocial health and functioning of Chinese patients with schizophrenia and their families.
