Descriptive study of the patients treated at the clinic “Integrated Dentistry for Patients with Special Needs” at Complutense University of Madrid (2…
2015
Objectives: To study clinical and epidemiological characteristics of the patients treated at the clinic “Integrated Dentistry for Patients with Special Needs (Special Care Dentistry)” at Complutense University of Madrid (UCM), as well as to know the dental treatments performed in these patients and the modifications from the usual treatment protocol. The information obtained from the results could also be applied in order to assess the needs of dental students education about this type of patients. Study Design: Medical records review of all the patients referred to the clinic of “Integrated Dentistry for Patients with Special Needs”, performing a retrospective cross-sectional study analyzi…
Binaural beats or 432 Hz music? which method is more effective for reducing preoperative dental anxiety?
2020
Background The aim of this prospective clinical study was to investigate the effectiveness of binaural beats and music at a frequency of 432 Hz and compare which method is more effective for reducing preoperative dental anxiety in impacted third molar surgery. Material and Methods Ninety patients were randomly selected to the binaural beats group, music group and control group. Visual analog scale used to evaluate dental anxiety before the local anesthesia in the first measurement. Local anesthesia was applied to the all patients. Patients in the music group listened to 432 Hz tuned music using earphones for 10 minutes. Patients in the binaural beats group listened to binaural beats using e…
Metabolic and Functional Improvements in a Patient with Charcot-Marie-Tooth Disease Type 2 after EGCG Administration: A Case Report.
2021
Background and objectives: The aim of this study was to report a case of a patient with Charcot-Marie-Tooth disease type 2 (CMT2) treated with epigallocatechin gallate (EGCG) for 4 months in order to assess its therapeutic potential in CMT2. Materials and Methods: The study included a brother and a sister who have CMT2. The sister received 800 mg of EGCG for 4 months, while her brother received placebo for the same period of time. Both participants were assessed before and after daily administration by means of anthropometry; analysis of inflammatory and oxidation markers of interleukin-6 (IL-6) and paraoxonase 1 (PON1) in the blood sample; and motor tests: 2-min walk test (2MWT), 10-m walk…
Complications of guided surgery and immediate loading in oral implantology: a report of 12 cases.
2011
Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheses with immediate function, have led to the development of software capable of planning and manufacturing a surgical guide and prosthesis that can be placed upon conclusion of the implant surgery step. The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgery technique, together with patient comfort during and after treatment. Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulous upper and/or lower maxillae, involving the placement of a total of 122 implants. …
Species-specific enamel differences in hardness and abrasion resistance between the permanent incisors of cattle (Bos primigenius taurus) and the eve…
2022
Hypselodont (ever-growing) teeth of lagomorphs or rodents have higher wear rates (of a magnitude of mm/week), with compensating growth rates, compared to the non-ever-growing teeth of ungulates (with a magnitude of mm/year). Whether this is due to a fundamental difference in enamel hardness has not been investigated so far. We prepared enamel samples (n = 120 per species) from incisors of cattle (Bos primigenius taurus) and nutria (Myocastor coypus, hypselodont incisors) taken at slaughterhouses, and submitted them to indentation hardness testing. Subsequently, samples were split into 4 groups per species (n = 24 per species and group) that were assessed for abrasion susceptibility by a sta…
Dental treatment of Marfan syndrome. With regard to a case.
2010
Marfan syndrome is the most common dominant autosomic genetic disorder of the connective tissue. It has a reported incidence of 1 per each 5000 individuals without any distinction of gender or ethnicity. This pathology?s diagnosis is mainly based on physical characteristics, presenting three main different symptomatic charts: neonatal Marfan, infant Marfan and classical Marfan. The mayor characteristic of these patients consists of an exaggerated length of the upper and lower limbs, hyperlaxity, scoliosis, alterations in the cardiovascular and pulmonary systems and atypical bone overgrowth. The individual implied in the present investigation concerned to a 14 year old male patient presentin…
Association between marfan syndrome and oral health status : a systematic review and meta-analysis
2019
Background: The purpose was to identify and assess the existing scientific evidence from epidemiologic, non-experimental, observational studies of associations between Marfan’s syndrome and oral diseases. Material and Methods: Electronic literature searches in MEDLINE (OVID), The Cochrane Library, Scopus and the Web of Science were conducted to identify all relevant articles. Eligibility was based on inclusion criteria, and quality assessments were conducted. The outcome variables were probing depth, gingival margin, clinical attachment level, bleeding on probing, gingival status, periodontal status, tooth mobility, furcation involvement and decayed, missing and filled teeth index. After ex…
Combining the COM-B Model and Habit Theory to Leverage Understanding of Adolescents’ Tooth-Brushing Behavior
2022
Although brushing teeth twice a day is not difficult, a surprisingly large proportion of adolescents do not behave accordingly. This paper brings together the COM-B model and the habit formation theory in order to create a basis for a more comprehensive, customer-oriented, theory-based understanding of the issue. A total of nine focus group interviews were conducted among adolescents to further understand underlying aspects and develop solutions. In findings, barriers related to adolescents tooth brushing behavior were identified in all areas of COM-B model. Especially the role of automatic motivation was highlighted as in mornings tooth brushing seemed not to have a stable place in daily r…
Comparison of spring characteristics of titanium-molybdenum alloy and stainless steel
2017
Background Titanium-molybdenum alloy (TMA) and stainless steel (SS) wires are commonly used in orthodontics as arch-wires for tooth movement. However, plastic deformation phenomenon in these arch-wires seems to be a major concern among orthodontists. This study aimed to compare the mechanical properties of TMA and SS wires with different dimensions. Material and Methods Seventy-two wire samples (36 TMA and 36 SS) of three different sizes (19×25, 17×25 and 16×22) were analyzed in vitro, with 12 samples in each group. Various mechanical properties of the wires, including spring-back, bending moment and stiffness were determined using a universal testing machine. Student’s t-test showed statis…
Physical-mechanical effects of Nd:YAG laser on the surface of sound dental enamel.
1993
Human dental enamel samples were irradiated using a 5 kHz Q-Switched Nd:YAG laser. An increase in Knoop microhardness and modification of the membrane permselectivity were detached. These results and the changes observed by SEM, can be connected with the fusion of the enamel surface.
