Objectives: The target of the current study was to evaluate and compare the shaping ability and buckling resistance of various single-file systems (TruNatomy [TRN], WaveOne gold [WOG], and XP-Endo Shaper [XPS]). Materials and Methods: Thirty recently extracted human first mandibular molars were chosen with severely curved mesiobuccal (MB) canals. Following access cavity preparation and determination of working length, teeth were randomly divided into three groups ( n = 10) according to the instrumentation technique used, Group 1 (TRN), Group 2 (WOG), and Group 3 (XPS)...

Introduction: Lichen planus (LP) is a relatively common chronic, mucocutaneous disease of autoimmune origin, involves oral mucosa, skin, scalp, nails, and genital mucosa. The prevalence of oral LP (OLP) varies worldwide, commonly seen in middle-aged and elderly people. It usually presents as symmetrical and bilateral or multiple lesions with burning sensation (BS) sometimes accompanied by pain. Corticosteroids and calcineurin inhibitors have shown promising results in the treatment of OLP, but its chronic course and unpredictable exacerbations/remission continues to result in a high degree of morbidity...

Introduction: Irrigants play an important role in the eradication of microorganisms in the complex root canal system. Sodium hypochlorite (NaOCl), chlorhexidine (CHX), and iodine potassium iodide (IKI) have certain limitations despite their routine clinical use. Surfactant irrigants with antimicrobial properties can be a milestone in endodontics to overcome the drawbacks of conventional irrigants. The aim of this study was to evaluate the antimicrobial efficacy of surfactants in comparison with routine endodontic irrigants on Enterococcus faecalis ...

Fibrous dysplasia (FD) is a developmental pathology of the bones in which normal bone is replaced by fibrous tissue and immature bone. It can affect single bone (monostotic) or multiple bones (polyostotic), sporadically or in association with McCune-Albright syndrome, Jaffe-Lichtenstein syndrome, or Mazabraud syndrome. When multiple bones in the craniofacial region are affected, the term "craniofacial FD" is used. Nonspecific cystic degeneration occurring in FD of the jaws has rarely been reported in the literature...

Background: A comparative analysis of protein expression of gingival crevicular fluid (GCF) obtained from healthy individuals and individuals with periodontal diseases would help to identify proteins involved in periodontal disease progression. Among the identified proteins, Moesin which is a disease-associated protein belongs to the ezrin-radixin-moesin protein family and was proved to play an important role in the recognition of oral bacteria contributing to the consequent development of inflammatory immune responses involved in periodontal disease development...

Aims: The aim of the study was to compare the clinical efficacy of platelet-rich fibrin (PRF) and connective tissue grafting in the treatment of gingival recession (GR) using pouch and tunnel (P and T) technique. Materials and Methods: A total of 40 Class I or Class II GR defects in 17 patients were randomized treated with P and T with PRF (Group I, n = 20) and P and T with CTG (Group II, n = 20). The parameters measured were plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), horizontal gingival recession (HGR), vertical gingival recession (VGR), width of attached gingiva (WAG), width of keratinised gingiva (WKG), gingival thickness-mid buccal (GTMB), and gingival thickness interdental papilla (GTIP)...

Background: Oral lichen planus (OLP) is a chronic inflammatory disease. Apoptosis of the basal keratinocytes is a causative factor for OLP pathogenesis but the detailed mechanism of apoptosis among nondysplastic and dysplastic OLP lesions is yet unraveled. Aims: This study aims to evaluate the involvement of cellular DNA fragmentation and alteration in the expression of Bcl-2 and B-cell lymphoma extra-large (Bcl-xL), p53, p21 and heat shock protein 70 (HSP70) in nondysplastic and dysplastic OLP lesions...

Regional odontodysplasia (RO), also called ghost teeth, is a rare nonhereditary developmental dental anomaly affecting the epidermal and mesenchymal tissues associated with the development of tooth which can affect both primary and permanent dentition. It can affect the child's overall quality of life and sometimes may lead to skeletal malocclusion. Management of such patients requires a multidisciplinary approach. Essix retainers are being widely used as retention appliances. Various modifications of this appliance are also being attempted...

Objectives: The aim of this systematic review was to assess the scientific evidence on the effect of rotary versus manual instrumentation for root canal preparation in primary teeth. Materials and Methods: Search terms were selected based on Medical Subject Headings (MeSH) and non-MeSH terms. Electronic database search of English published literature was performed in March 2020 within the following databases: Scopus, Cochrane, PubMed, and Embase. The risk of bias of selected studies was assessed by means of Cochrane collaboration tool...

Aims: The purpose of this randomized controlled clinical trial was to clinically assess soft tissue augmentation and compare patients' morbidity and root coverage outcomes of coronally advanced flap (CAF) with subepithelial connective tissue graft (SCTG) versus de-epithelialized free gingival graft (DFGG) in the management of Miller Class I and II gingival recession. Materials and Methods: Twenty-eight patients with Miller's Class I or II gingival recession (GR) defects were randomly assigned into two equal parallel groups treated with either CAF + SCTG, harvested using single-line incision technique (control), or CAF + DFGG (test)...

Context: Improved esthetics is an important factor for most patients undergoing orthognathic surgery. Thus, a treatment simulation that can provide patients with a realistic view of the esthetic outcome after surgery is important in clinical practice. Aims: To evaluate the accuracy of simulations generated using algorithms specific for patient's type of malocclusion and surgical procedure compared to nonspecific algorithms. Settings and Design: A total of 36 patients (average age 18...

Background: Pediatric dentists face difficulties in treating tooth decay of children with difficulty in opening the mouth. This is especially true, as the main disease is accompanied by such symptoms as arthritis, osteoarthritis, myositis, myalgia, sclerosis, and oral atrophy. Aim: The aim was to increase the level of treatment of fissure tooth decay for children with rheumatic diseases, using the silicone key method (SKM). Materials and Methods: A dental examination of 82 children was carried out, with diagnoses: systemic lupus erythematosus, juvenile systemic scleroderma, juvenile dermatomyositis, and juvenile rheumatoid arthritis...

This clinical report describes the oral rehabilitation with a mandibular overdenture retained by telescopic crowns and ball attachments on semierupted permanent teeth with a 5-year follow-up. A female patient used an old complete denture in the maxilla and was willing to extract her remaining mandibular teeth to have new dentures. The treatment included preservation of semierupted premolars because of the high surgical risk for mandibular fracture and paresthesia, a new maxillary complete denture, and a mandibular overdenture supported by combined telescopic crowns and ball attachments...

Background: It is known that a large number of mediators involved in osteogenesis can influence bone development and repair; however, whether these mediators could be used as markers of bone maturity has yet to be determined. Aim: To evaluate the expression of osteocalcin (OC) and Runt-related transcription factor 2 (Runx2) in bone biopsies obtained during the reconstruction of atrophic anterior maxillae using particulate bone xenografts with or without association of autogenous bone marrow aspirate concentrate (BMAC)...

Aim: The aim of the study was to determine the effect of different anterior reference points during facebow transfer, on sagittal inclination of occlusal plane (SIOP) and horizontal condylar guidance (HCG) values obtained on arcon and nonarcon articulators. Materials and Methods: Facebow records of 25 participants were made and transferred to Hanau Wide-Vue (WV) and Hanau H2 (H2) articulators using conventional indirect transfer (CIT), superior annular groove (SAG), and inferior annular groove (IAG) as anterior reference points...

Although techniques such as subepithelial connective tissue graft are now widely used for root coverage procedures, free gingival graft (FGG) continues to be a common mucogingival procedure used to increase keratinized tissue dimensions. However, the palatal donor site heals with secondary intention and requires a longer healing time causing more discomfort and pain to the patient. A healthy 22-year-old female patient presented with Miller's class II recession in relation to the tooth 31 with high frenal attachment and a shallow vestibule, which was treated using FGG, and the donor site was bandaged with advanced-platelet-rich fibrin (A-PRF)...

Background: Radiography plays an important role in detection of interproximal caries. The aim of study is to compare diagnostic ability of conventional film and photostimulable phosphor (PSP) with direct measurement using stereomicroscope in detecting proximal caries. Methodology: In this descriptive study - diagnostic test evaluation, 200 proximal surfaces of 100 extracted human posterior teeth were radiographed with dental X-ray unit. Evaluation of conventional and digital radiographs was performed twice by three observers...
