Background/purpose
Oral submucous fibrosis (OSF) affecting populations is considered a public health issue in South/Southeast Asia. The purpose of this study was to analyze the scientometric characteristics and research trends of OSF.
Materials and methods
All the papers on OSF were comprehensively retrieved from the Scopus database. Regional comparison (India versus outside of India) and chronological comparison (before 2015 versus after 2015) were performed.
Results
Among all the 1357 papers on OSF, 930 (68.5%) were from India. In India, biology research on antioxidant, oxidative stress, angiogenesis, and extracellular matrix were distinctive keywords. Risk factors of smokeless tobacco and gutkha and the roles of saliva and blood sampling were also distinctive keywords in India. In outside of India, biology research on myofibroblast, alpha smooth muscle actin, microRNA, long untranslated RNA, and protein p53 were distinctive keywords. The trend of biology research on connective tissue, genotype, genetic predisposition, messenger RNA, and cytology before 2015 has changed to research on myofibroblast, biological marker, microRNA, epithelial mesenchymal transition, extracellular matrix, and oxidative stress after 2015. The trend of clinical aspects of surgery and mouth hygiene before 2015 has changed to the aspects of adverse event/effects, complication, and quality of life after 2015.
Conclusion
This scientometric study elucidated the current scenario and research trends of OSF, and would help in improving in reciprocal collaboration and communication for this disease control in South/Southeast Asia.

Background/purpose
The diagnosis and treatment of Sjogren's syndrome (SS) are commonly conducted by rheumatologists and stomatologists. The purpose of this study was to compare the scientometric characteristics of SS publications by rheumatologists and stomatologists.
Materials and methods
All the papers on cheilitis were comprehensively retrieved from the Scopus database, and divided into rheumatologists and stomatologists groups.
Results
There were 3245 and 1209 papers on SS were published by rheumatologists and stomatologists, respectively. For the most-cited top-200 papers, the total citation count was 29,764 and the h index was 108 for SS publications by rheumatologists; whereas the count is 19,891 and h index is 81 for publications by stomatologists. Interestingly, we observed that accumulated citations of the publications by stomatologists cooperated with rheumatologists were larger than those by stomatologists alone during 2012–2022. The more common keywords such as saliva, salivation, minor salivary glands, parotid gland, submandibular gland, sialography, lip, dental caries, and hyposalivation were reported by stomatologists. The more frequent keywords such as rheumatoid factor, fatigue, lymphoma, interstitial lung disease, arthralgia, Raynaud phenomenon, lymphadenopathy, and vasculitis were reported by rheumatologists.
Conclusion
This study firstly reports the scientometric characteristics of SS publications by rheumatologists and stomatologists. The scale and citations of rheumatologists' publications greatly outweigh those of stomatologists, suggesting stomatologists can cooperate more with rheumatologists regarding SS research.
背景/目的风湿免疫科医生和口腔科医生通常都会对斯尤格林综合征(SS)进行诊断和治疗。本研究的目的是比较风湿免疫科医生和口腔科医生发表的斯约格伦综合征论文的科学计量学特征。结果风湿免疫科医生和口腔科医生分别发表了 3245 篇和 1209 篇有关斯约格伦综合征的论文。在被引用次数最多的前 200 篇论文中,风湿病学家发表的 SS 论文的总引用次数为 29764 次,h 指数为 108;而口腔医学家发表的 SS 论文的总引用次数为 19891 次,h 指数为 81。有趣的是,我们观察到,2012-2022 年期间,口腔科医生与风湿病学家合作发表的论文的累计引用次数大于口腔科医生单独发表的论文。唾液、流涎、小唾液腺、腮腺、颌下腺、唾液造影、唇、龋齿和唾液分泌过少等关键词在口腔科医生的报告中较为常见。类风湿因子、疲劳、淋巴瘤、间质性肺病、关节痛、雷诺现象、淋巴腺病和血管炎等关键词的出现频率较高。风湿免疫科医生发表的论文在规模和引用次数上都大大超过了口腔科医生,这表明口腔科医生可以在SS研究方面与风湿免疫科医生开展更多合作。

Anterior open bite (AOB), characterized by the lack of vertical overlap between upper and lower anterior teeth, poses a considerable challenge in orthodontics. The condition depends on many factors that combine to render it difficult to achieve post treatment stability. AOB is commonly classified as dental, skeletal, or functional on the basis of the clinical presentation and causative factors. Traditionally, skeletal AOB necessitates surgical intervention, whereas nonsurgical approaches such as extrusion arches and the Multiloop Edgewise Archwire Technique (MEAW) can be employed in more straightforward cases. Functional appliances are reserved for situations in which a patient's growth potential offers the possibility of effectively addressing AOB. This review presents a strategic treatment approach for addressing AOB, taking into account the classification and severity of the condition. The proposed SHE framework describes the use of mini-screws (S) for anchorage and vertical control, encouragement to correct habits (H), and the utilization of extractions and elastics (E). By incorporating extra-radicular mini-screws, AOB closure is achieved through anterior retraction in extraction cases or whole arch distalization of dentition with elastics in non-extraction cases. This framework emphasizes habit correction through a regimen of oral myofunctional therapy (OMT) and habit-correcting appliances to enhance posttreatment stability. This review suggests that nonsurgical correction is viable in the majority of cases, whereas surgical intervention should be reserved for severe cases of skeletal vertical overgrowth or horizontal discrepancies.

Background/purpose
In the field of conservative dentistry and endodontics, mineral trioxide aggregate (MTA), commonly used, possesses advantages such as biocompatibility, antimicrobial properties and osteogenic potential. This study investigated the feasibility of utilizing membrane form mineral trioxide aggregate (MTA) as a barrier membrane in guided bone regeneration (GBR) procedures.
Materials and methods
Membranes were electrospun from three different formulations: 15 w/v% Polycaprolactone (PCL), 13 w/v% PCL + 2 w/v% MTA (2MTA), and 11 w/v% PCL + 4 w/v% MTA (4MTA). Physicochemical and mechanical properties of the electrospun membrane were compared, encompassing parameters such as surface morphology, fiber diameter distribution, chemical composition, phase identification, tensile stress, pH variation, and water contact angle. Moreover, the antimicrobial properties against of the electrospun membranes were assessed through direct exposure to streptococcus aureus (S. aureus) and candida albicans (C. albicans). Additionally, on the 7th day, biocompatibility and cell attachment were investigated with respect to L929 (fibroblast) and MC3T3 (pre-osteoblast) cells. Inhibition of L929 cell infiltration and the expression of osteogenic related genes including osteocalcin (OCN), alkaline phosphatase (ALP), and runt related transcription factor 2 (RUNX2) in MC3T3 cells on 7th and 14th days were also investigated.
Results
PCL, 2MTA, and 4MTA exhibited no statistically differences in fiber diameter distribution and tensile stress. However, as the MTA content increased, wettability and pH also increased. Due to the elevated pH, 4MTA demonstrated the lowest viability S.aureus and C.albicans. All membranes were highly biocompatibility and promoted cell attachment, while effectively preventing L929 cell infiltration. Lastly 4MTA showed increase in OCN, ALP, and RUNX2 expression on both 7th and 14th day.
Conclusion
The membrane form MTA possessed characteristics essential for a novel barrier membrane.

Background/purpose
The etiology of the ectopic eruption (EE) of the maxillary first permanent molars (FPM) remains unclear and controversial. This study was designed to explore the dental and skeletal factors for EE of the FPM in children.
Materials and methods
Children aged 6–10 years were recruited to this study. Subjects were assigned to the ectopic eruption group (EEG) and the normal eruption group (NEG). Lateral cephalometric radiographs and panoramic radiographs were measured by angular and linear indices.
Results
The prevalence of EE of maxillary FPM was higher in males and at younger ages. Subjects with skeletal class III malocclusion were more likely to be diagnosed with EE of maxillary FPM. The SNA, ANB, FMIA, Wits, Ptm-A, ANS-PNS, overbite, and overjet were significantly different between the EEG and the NEG. The length of the posterior region of the maxillary alveolar bone, U6-OP, and eruptive angulation of the maxillary FPM were statistically different between the two groups.
Conclusion
Male sex, skeletal class III malocclusion, mesial inclination of the maxillary FPM, hypoplasia of the maxilla, and insufficient length of the posterior region of the maxillary alveolar bone were related to EE of the maxillary FPM.
