Sjogren's Syndrome (SS) is a chronic, female overwhelming fundamental issue of an immune system rheumatic sickness that influences the whole body. It is described by lymphocytic invasion of the exocrine viz. salivary and lacrimal glands and by surprising B-cell hyperactivity. Keratoconjunctivitis sicca (dry eye) and Stomatitis sicca (oral dryness) is the primary visual appearance of SS. The primary SS is recognized from secondary SS which happens as a piece of other immune system maladies. The secondary SS exists together particularly with fundamental lupus erythematosus (15- 36%), rheumatoid joint inflammation (20- 32%) and also restricted and progressive systemic sclerosis (11- 24%), less as often as possible with different sclerosis and immune system hepatitis and thyreoiditis...

OBJECTIVE: Depth of invasion (DOI) in oral carcinoma has been integrated into the primary tumor categories in the current tumor-node-metastasis staging (8th edition). However, there is no standard modality to determine DOI preoperatively. The aims of the present study were to evaluate the accuracy of a preoperative measurement of DOI using ultrasonography (US) for superficial oral tongue carcinomas, and to correlate the values obtained with histologically determined DOI measurements. METHODS: We retrospectively analyzed the records of 56 patients with oral tongue carcinoma who underwent intraoral US preoperatively, followed by curative surgery at the Shizuoka Cancer Center Hospital in Japan...

This study aimed to compare the diagnostic efficacy of VistaCam iX intraoral camera system using infrared light and bitewing radiography for detection of proximal caries in permanent teeth. This in vitro study was performed on 108 teeth. The proximal surfaces of the teeth were examined for caries using ICDAS II criteria, bitewing radiography, and the Proxi head of VistaCam iX. The teeth were then sectioned and histologically analyzed (gold standard). Data were analyzed using SPSS version 25 via the correlation test at P < 0...

Intraoral Vertical Ramus Osteotomy (IVRO) is one of the operative techniques used for orthognathic surgery. The aim of this study was to assess the posterior displacement of the proximal segment in patients undergoing IVRO at 1-year follow-up. In total, 52 hemimandibles from 26 patients who underwent IVRO in whom the proximal segment was posteriorly displaced without overlap with the distal segment at immediate post-operation (Imm) (30 cases, experimental group), and 26 patients in whom the proximal segment was not posteriorly displaced with overlap with the distal segment (Imm) (22 cases, control group) under three-dimensional computed tomography (3D CT) were included in the study...

PURPOSE: To: (1) determine which preparation techniques clinicians use in routine clinical practice for single-unit crown restorations; (2) test whether certain practice, dentist, and patient characteristics are significantly associated with these techniques. METHODS: Dentists in the National Dental Practice-Based Research Network participated in a questionnaire regarding preparation techniques, dental equipment used for single-unit crown preparations, scheduled chair time, occlusal clearance determination, location of finish lines, magnification during preparation, supplemental lighting, shade selection, use of intraoral photographs, and trimming dies...

BACKGROUND: Glomus tumors are rare benign neoplasms that usually occur in the upper and lower extremities. Oral cavity involvement is exceptionally rare, with only a few cases reported to date. CASE PRESENTATION: A 24-year-old woman with complaints of swelling in the left floor of her mouth for 6 months was referred to our institution. Her swallowing function was slightly affected; however, she did not have pain or tongue paralysis. Enhanced computed tomography revealed a 2...

PURPOSE: To compare the accuracy of implant impressions using computer-aided impression-making technology and a conventional approach in a standardized setting in vitro, and to verify the effect of implant angulation (40 to 45 degrees) on the accuracy of digital and conventional impression-making procedures. MATERIALS AND METHODS: Four different edentulous mandibular reference models (RMs) were manufactured. Two straight (RM1); four straight (RM2); two straight and two tilted (RM3); and six straight (RM4) dental implants were placed, simulating four different clinical scenarios...

The mock-up is a diagnostic technique that allows for the intraoral try-in of a prosthetic rehabilitation. Mock-ups facilitate significant improvement in communication with patients by showing them the potential final outcome of the treatment. They also allow for a quick and easy comparison of the pre- and postoperative situations, and permit the clinician to check the functional aspects of the therapy. The purpose of this article is to describe the use of the full-mouth mock-up technique for testing all the functional and esthetic parameters of extensive rehabilitations associated with a VDO increase with completely additive wax-ups...

OBJECTIVES: This in vivo study aimed to compare the marginal discrepancies of zirconia copings manufactured on the basis of two direct intraoral scanning systems and the indirect digitization of a conventional impression. MATERIALS AND METHODS: A total of 63 teeth in 23 patients were prepared to receive full-coverage crowns. Subsequently, these teeth were intraorally scanned using CEREC AC Omnicam and Cara TRIOS and a conventional impression was taken with the scannable PVS Flexitime Fast & Scan...

BACKGROUND: Correction of tear trough (TT) deformity is a crucial aspect of facial rejuvenation. Because the anatomical origins of TT deformity lie in the TT ligaments, which firmly attach the dermis to the periosteum, the release of TT ligaments should be considered when performing an etiological correction. The aim of this paper is to propose an alternative method for TT deformity correction, comprising use of filler together with the release of TT ligaments. This technique was compared to the procedure of only percutaneous filler...

Brown tumor is a bone lesion that arises in the setting of excess osteoclast activity in hyperparathyroidism. It consists of fibrous tissue, woven bone, and supporting vasculature, while contains no matrix. The characteristic of brown-colored lesion is a result of hemosiderin deposition into the osteolytic cysts. Two cases of young women aged 26 and 29 years old, respectively, are known with a history of end-stage renal disease (ESRD). Dialysis is performed two times/week over the last 7 years. Our patients presented with an intraoral mass of the hard palate since 12 months ago and decreased body height of 10 cm...

Full-arch, fixed, implant-supported prostheses can be designed to be cement- or screw-retained. Both retention mechanisms have a few inherent disadvantages. A fixed attachment system has been introduced to circumvent the disadvantages of both screw and cement retention. This system eliminates the screw access holes and the use of cement. The number of intraoral procedures required is also reduced. The purpose of this article is to report a case using the Locator F-Tx Attachment System to facilitate fabrication of an esthetic, clinician-retrievable, full-arch implant-supported fixed dental prosthesis...

BACKGROUND: Invasive cervical resorption (ICR) is a relatively uncommon form of external tooth resorption, characterized by an invasive nature. It is usually painless and detection of lesions is often made incidentally. Three-dimensional imaging techniques, such as cone beam computed tomography (CBCT), are useful in the diagnosis and management of ICR as the true extent of the defect cannot always be estimated using conventional radiographs. AIM: The aim of this article is to report on the successful treatment of ICR in mandibular first molar by nonsurgical approach and follow-up by means of CBCT...
