Use of high- and low-intensity lasers in the treatment of dentin hypersensitivity: A literature review
2021
Background Dentin hypersensitivity (DH) is defined as an exaggerated sensitivity of vital dentin exposed to thermal, chemical and tactile stimuli. This study aimed to evaluate, through a literature review, the applicability of high- and low-intensity lasers in the treatment of DH for the past 10 years, as well as its therapeutic potential. Material and methods The electronic databases MEDLINE/PubMed and LILACS were searched using the descriptors ("Dentin Sensitivity" OR "Dentin Hypersensitivity") AND ("Low-Level Therapy" OR Laser), for articles published between 2010 and 2020. Only randomized clinical trials with full-text and full case resolution were included. Results We found 187 article…
Mutations in the MORC2 gene cause axonal Charcot-Marie-Tooth disease
2016
Charcot-Marie-Tooth disease (CMT) is a complex disorder with wide genetic heterogeneity. Here we present a new axonal Charcot-Marie-Tooth disease form, associated with the gene microrchidia family CW-type zinc finger 2 (MORC2). Whole-exome sequencing in a family with autosomal dominant segregation identified the novel MORC2 p. R190W change in four patients. Further mutational screening in our axonal Charcot-Marie-Tooth disease clinical series detected two additional sporadic cases, one patient who also carried the same MORC2 p. R190W mutation and another patient that harboured a MORC2 p. S25L mutation. Genetic and in silico studies strongly supported the pathogenicity of these sequence vari…
The face of conflict: Significant sharp force trauma to the mid-facial skeleton in an individual of probable 16th–17th century date excavated from By…
2016
A variety of injuries have always been associated with violence, consequences of which people had to deal with. In this paper we present a complex of craniofacial and dental injuries resulted from sharp force trauma. The basis of our study was historical skeletal material excavated from archeological site in Byczyna (11th–17th century), Poland. An individual whose skeleton was exhumed from the grave No. 610 exhibited healed, oblique trauma of the left maxilla, damage to the crowns of right central and lateral incisors and concomitant luxation of the right maxillary central incisor. We describe the mechanism of this trauma and complications that resulted from damage to the masticatory appara…
Oral Health Status in Subjects with Amnestic Mild Cognitive Impairment and Alzheimer’s Disease: Data from the Zabút Aging Project
2020
Background: The relationship between Alzheimer’s disease (AD) and periodontitis has been recently investigated with heterogenous results. Objective: This study aims to evaluate the oral health status and its relationship with cognitive impairment of participants, enrolled in the Zabút Aging Project, a community-based cohort study performed in a rural community in Sicily, Italy. Methods: A case-control study (20 subjects with AD, 20 with amnestic mild cognitive impairment [aMCI], and 20 controls) was conducted. The protocol included a comprehensive medical and cognitive-behavioral examination. Full-mouth evaluation, microbial analysis of subgingival plaque samples (by RT-PCR analysis), and o…
Mesenchymal stem cells derived from inflamed dental pulpal and gingival tissue: a potential application for bone formation
2017
Background Chronic periodontal disease is an infectious disease consisting of prolonged inflammation of the supporting tooth tissue and resulting in bone loss. Guided bone regeneration procedures have become common and safe treatments in dentistry, and in this context dental stem cells would represent the ideal solution as autologous cells. In this study, we verified the ability of dental pulp mesenchymal stem cells (DPSCs) and gingival mesenchymal stem cells (GMSCs) harvested from periodontally affected teeth to produce new mineralized bone tissue in vitro, and compared this to cells from healthy teeth. Methods To characterize DPSCs and GMSCs, we assessed colony-forming assay, immunophenot…
Comparison of peri-implant soft tissues in submerged versus transmucosal healing: A split mouth prospective immunohistochemical study
2018
Objective The present split-mouth prospective study involves an immunohistochemical evaluation of peri-implant soft tissue healing after the osseointegration period, comparing submerged and transmucosal approaches using two-piece implant systems. The null hypothesis was that both surgical procedures elicit a similar immune response of the peri-implant soft tissues. Design Thirty-one healthy patients were included in this study, in which two implants were placed in the right and left maxillary pre-molar regions. A total of 62 dental implants were analyzed, establishing a control side with 31 submerged implants, and a study side with 31 exposed implants bearing healing abutments. After a thre…
Tooth loss in middle-aged adults with diabetes and hypertension: Social determinants, health perceptions, oral impact on daily performance (OIDP) and…
2018
Background This study aimed to explore the association between tooth loss and social determinants, health self-perceptions, OIDP and self-concept of dental treatment need in middle-aged adults with diabetes and hypertension. Material and Methods A cross-sectional study was developed with 212 hypertensive and diabetic middle-aged adults (50-65 years). Data were collected from clinical examinations (DMFT) and a questionnaire regarding socioeconomic status, dental health assistance, self-perceptions of oral and general health, OIDP, and the self-concept of dental treatment need. Tooth loss was dichotomized considering the cutoff point of 12 (Model I) or 24 missing teeth (Model II). Data were a…
Prevalence of traumatic dental injuries and role of incisal overjet and inadequate lip coverage as risk factors among 4-15 years old government schoo…
2010
Objective: To assess the prevalence of traumatic dental injuries (TDI) in school children in Baddi- Barotiwala, Himachal Pradesh, India. Methods: A cross-sectional survey was carried out in Government schools among 1059 government school children aged 4- 15 years. The study was conducted from October 2009 to March 2010 during the school hours. The demographic detail was carried on a structured questionnaire. The data regarding the traumatic injuries was recorded using modified Ellis' classification. Results: Prevalence of TDI was found to be 4.15%. 95.45% of the injuries were to the maxillary anterior teeth. Maxillary central incisor was the most common tooth to be affected due to trauma (5…
The Treatment of Anterior Dental Trauma
2011
Anterior dental trauma is a common injury pattern of the dentoalveolar system in which appropriate first aid is important. When children and adolescents suffer an anterior dental trauma, the challenge is to preserve the tooth in this esthetically important area and minimize subsequent damage. Lack of treatment or improper treatment can lead to a lifelong need for dental care. There are many causes of anterior dental trauma. At the age of one and two years, it is mainly caused by falls when learning to walk. At preschool age, between two and six years, many such injuries are caused by falls resulting from lack of attention when engaging in physical play. The highest incidence of anterior den…
Plaque levels of patients with fixed orthodontic appliances measured by digital plaque image analysis
2011
Introduction A digital plaque image analysis system was developed to objectively assess dental plaque formation and coverage in patients treated with fixed orthodontic appliances. Methods The technique was used to assess plaque levels of 52 patients undergoing treatment with fixed appliances in the Department of Orthodontics at Johannes Gutenberg University in Mainz, Germany. Results Plaque levels ranged from 5.1% to 85.3% of the analyzed tooth areas. About 37% of the patients had plaque levels over 50% of the dentition, but only 10% exhibited plaque levels below 15% of tooth coverage. The mean plaque coverage was 41.9% ± 18.8%. Plaque was mostly present along the gum line and around the or…
