The gingiva contains leptin and leptin receptor in health and disease
Shigaku = Odontology - Tập 100 - Trang 222-231 - 2011
Zuhal Yetkin Ay, F. Yeşim Kırzıoğlu, Mine Öztürk Tonguç, Recep Sütçü, Nilgün Kapucuoğlu
The presence of leptin (OB) and soluble OB receptor (s-OB-R) in gingival tissue extract and gingival crevicular fluid has led the studies investigating the relationship between OB and periodontal diseases. This study aims to investigate the levels of OB and s-OB-R in serum and their presence in gingiva of healthy controls (HC), gingivitis (G), aggressive periodontitis (AP), and chronic periodontit...... hiện toàn bộ
Clinical study on natural gingival color
Shigaku = Odontology - Tập 107 - Trang 80-89 - 2018
Cristina Gómez-Polo, Javier Montero, Miguel Gómez-Polo, Ana María Martín Casado
The aims of the study were: to describe the gingival color surrounding the upper incisors in three sites in the keratinized gingiva, analyzing the effect of possible factors which modulate (socio-demographic and behavioral) intersubject variability; to study whether the gingiva color is the same in all three locations and to describe intrasubject color differences in the keratinized gingiva band. ...... hiện toàn bộ
Characterization of cGMP-related phosphodiesterase isoenzymes in rat salivary glands
Shigaku = Odontology - Tập 90 - Trang 0007-0012 - 2002
N. Komine, H. Shimomura
Isolation and characterization of the cGMP-related phosphodiesterase (PDE) isoenzymes in rat salivary glands were investigated. Both cGMP- and cAMP-PDE activities were mainly present in the 100 000 g supernatant fractions from the parotid, submandibular, and sublingual glands. The results of inhibition studies and ion-exchange chromatography suggest that Ca2+/calmodulin markedly stimulates PDE1 i...... hiện toàn bộ
Effect of antimicrobial photodynamic therapy (aPDT) on the sterilization of infected dentin in vitro

Association of gingival recession and other factors with the presence of dentin hypersensitivity
Shigaku = Odontology - Tập 102 - Trang 42-49 - 2013
Yoshikazu Fukumoto, Masumi Horibe, Yuji Inagaki, Keiji Oishi, Naofumi Tamaki, Hiro-O Ito, Toshihiko Nagata
Dentin hypersensitivity (DH) may be present in association with gingival recession. The aim of this study was to determine quantitatively the association of gingival recession and other factors with the presence of DH. One hundred and four Japanese subjects with or without gingival recession were randomly selected. Intact canines and/or first premolars in both maxillary and mandibular quadrants we...... hiện toàn bộ
Effect of apical size on apical pressure during syringe-needle and multisonic negative pressure irrigation
Shigaku = Odontology - Tập 109 - Trang 625-631 - 2021
Binwen Chen, Ya Shen, Jingzhi Ma, Markus Haapasalo
Apical pressure during root canal irrigation is regarded as a key factor affecting the risk of irrigant extrusion. The aim of this study was to examine the effect of apical size on the apical pressure by positive and negative pressure syringe-needle and multisonic negative pressure irrigation. An extracted maxillary first molar with two separate buccal roots, one palatal root and four canals was s...... hiện toàn bộ
Caries diagnosis using light fluorescence devices: VistaProof and DIAGNOdent
Shigaku = Odontology - Tập 102 - Trang 330-335 - 2013
E. Betrisey, N. Rizcalla, I. Krejci, S. Ardu
The modern concept of minimally invasive dentistry encompasses early detection of incipient carious lesions and their treatment. Due to the low sensitivity of visual inspection and radiography in the detection of occlusal hidden carious lesions under a macroscopically sound surface, several devices have been developed to increase detection accuracy. DIAGNOdent is one of the tools used for that pur...... hiện toàn bộ
Differences in periodontal parameters between SPT patients who regularly and irregularly visited the dental clinic analyzed at tooth level: a 14-year retrospective cohort study
Shigaku = Odontology - Tập 111 - Trang 493-498 - 2022
Tomotaka Kato, Satoshi Sekino, Natsuki Fujiwara, Yukihiro Numabe
The purpose of this study was to evaluate the periodontal status of patients who routinely did SPT, when compared to patients that did not SPT. This retrospective cohort study was conducted at a general dental office from 2001 to 2019. Patients aged 18 to 81 years who visited the dental office over a 10-year period were assigned into two groups: an SPT group, which included patients who continuall...... hiện toàn bộ
Clinical oral dryness score: evaluation of a new screening method for oral dryness
Shigaku = Odontology - Tập 106 - Trang 439-444 - 2018
Derk H. Jan Jager, Casper P. Bots, Tim Forouzanfar, Henk S. Brand
The purpose of this study was to explore the association of the clinical oral dryness score (CODS) with salivary flow rates, xerostomia inventory (XI), and bother index (BI). 147 patients were screened using CODS, which determined 10 features of oral dryness. Each feature contributed 1 point, and the total score varied from 0 to 10. Unstimulated (UWS), chewing-stimulated (CH-SWS) and acid-stimulat...... hiện toàn bộ
External validation of cone-beam computed tomography- and panoramic radiography-featured prediction models for inferior alveolar nerve injury after lower third molar removal: proposal of a risk calculator
Shigaku = Odontology - Tập 111 - Trang 178-191 - 2022
Seiko Kubota, Tomoaki Imai, Ayano Nishimoto, Shigeki Amekawa, Narikazu Uzawa
We previously developed basic and extended models to predict inferior alveolar nerve injuries (IANI) after lower third molar (LM3) removal based on cone-beam computed tomography (CBCT) images. Although these models comprised predictors, including increased age and inferior alveolar canal-related CBCT factors, external validations were lacking. Therefore, this study externally validated these model...... hiện toàn bộ
