An evaluation of peri-implant marginal bone loss according to implant type, surgical technique and prosthetic rehabilitation: a retrospective multicentre and cross-sectional cohort study.

To evaluate implant loss (IL) and marginal bone loss (MBL); follow-up period of up to 10 years after prosthetic loading. Retrospective multi-centre cross-sectional cohort study. Double analysis: (1) all the implants (n = 456) were analysed; (2) to allow for possible cluster error, one implant per patient (n = 143) was selected randomly.

Effectiveness of salivary stimulation using xylitol-malic acid tablets as coadjuvant treatment in patients with gastro-oesophageal reflux disease: early findings.

Background: Besides dental erosion syndrome, other oral syndromes could benefit from the stimulation of salivary secretion, in patients with gastro-oesophageal reflux disease (GORD). Our aims is evaluate the improvement of oral extra-oesophageal manifestations in patients with GORD using xylitol-malic acid tablets to stimulate salivary secretion.

Material And Methods: The effectiveness of salivary stimulation using xylitol-malic acid tablets (as a supplement to omeprazole 40 mg/day) was assessed in a clinical trial (n = 14) lasting six months with patients with prior positive pH-metry, through GORD extra-oesophageal clinical signs, GerdQ and RDQ questionnaires, odontological variables, basal salivary secretion, stimulated salivary secretion, pH and buffer capacity, mucosal erythema index and dental wear.

Using Genetics in Periodontal Disease to Justify Implant Failure in Down Syndrome Patients.

Unlabelled: Peri-implant bone loss leading to dental implant failure does not develop in the same way across subjects who apparently present the same condition-specifically, in the case of Down syndrome patients with the same genetic disorder-given that they do not necessarily develop immune-inflammatory disorders to the same extent.

Methods: This retrospective case-control study was aimed at identifying the possible genes involved in implant failure in Down syndrome patients by matching the periodontal disease variable by means of a retrospective case-control study. This process involved using the functional analysis of gene expression software Transcriptome Analysis Console (TAC, Affymetrix, Thermo Fisher Scientific, Waltham, MA, USA) and a search for the possible candidate genes involved.

Bone loss around narrow implants versus standard diameter implants: Retrospective 2-years case-control study.

Background: The objectives were to evaluate the bone loss (BL) around narrow diameter implants (3.3 mm) 2 years after implant loading and compare with the bone loss around conventional-diameter implants (4.1 mm), as well as with clinical and anatomical variables.

Influence of marginal bone loss on peri-implantitis: Systematic review of literature.

Background: The marginal bone of dental implants is subjected to slight load modifications over time, conditioning implant survival. Objective: Perform a systematic review of the literature analyzing the factors that contribute to marginal bone loss (MBL) and the subsequent development of peri-implantitis.

Material And Methods: Bibliographic research in the databases PubMed, Medline and Scopus between 2010 and 2018 was performed.

Metallothioneins in Failure of Dental Implants and Periodontitis Down Syndrome Patients.

Background: Sometimes dental implants seem to be the only therapeutic alternative for the oral rehabilitation of patients with Down syndrome, given that they usually lose all their teeth early due to suffering aggressive periodontitis and they do not usually have the skills required to wear removable prostheses. However, the evolution of dental implants in these patients shows very adverse results. It is possible that basal genetic alterations, or at least some characteristics of these, may underlie these clinical results.

Dental implants placement in paranoid squizofrenic patient with obsessive-compulsive disorder: A case report.

Background: Paranoid schizophrenia is a mental illness that involves no observable anatomical alteration. Main characteristic affects the personality of the individual, as well as areas of his own psychology.

Case Report: A 33-year-old man with paranoid schizophrenia and obsessive-compulsive disorder in treatment with Haloperidol, Oxcarbazepine, Olanzapine and Seroquel is presented.

Production of bone mineral material and BMP-2 in osteoblasts cultured on double acid-etched titanium.

Background: The study of osteoblasts and their osteogenic functions is essential in order to understand them and their applications in implantology. In this sense, this study try to study BMP-2 production and bone matrix deposition, in addition to other biological variables, in osteoblasts cultured on a rough double acid-etched titanium surface (Osseotite®, Biomet 3i, Palm Beach Garden, Florida, USA) in comparison to a smooth titanium surface (machined) and a control Petri dish.

Materials And Methods: An in vitro prospective study.

Four years survival and marginal bone loss of implants in patients with Down syndrome and cerebral palsy.

Objectives: To evaluate implant survival rate and marginal bone loss (MBL) after 4 years in patients with Down syndrome and cerebral palsy, compared with a healthy control group.

Material And Methods: The case group comprises 102 implants in 19 patients (71 cerebral palsy, 21 Down syndrome), and the control group comprises 70 implants in 22 healthy patients. One implant per patient was selected (n = 41 implants) to take clustering effects into account.

Current methods of sedation in dental patients - a systematic review of the literature.

Objective: The main objective of this systematic literature review is to identify the safest and most effective sedative drugs so as to ensure successful sedation with as few complications as possible.

Study Design: A systematic literature review of the PubMed MEDLINE database was carried out using the key words "conscious sedation," "drugs," and "dentistry." A total of 1,827 scientific articles were found, and these were narrowed down to 473 articles after applying inclusion and exclusion criteria.

A systematic review of the oral and craniofacial manifestations of cri du chat syndrome.

Cri du chat syndrome is an autosomal disorder. Because it affects few people in the population it is considered a rare disease, yet it is one of the most common autosomal chromosomal syndromes in humans. It entails pathognomonic alterations that affect the craniofacial and oral anatomy of patients.

Relationship Between Osteoporosis and Marginal Bone Loss in Osseointegrated Implants: A 2-Year Retrospective Study.

Background: Fitting implants in osteoporotic patients has traditionally been controversial, and there is little scientific evidence relating osteoporosis to marginal bone loss (MBL). The aims of this study are as follows: 1) to evaluate the possibility of a correlation between osteoporosis, as measured by the mandibular cortical index (MCI), and MBL and 2) to assess how various systemic diseases, periodontitis, and placement of implants in regenerated bone are correlated with MBL and MCI.

Methods: This retrospective study examines 212 implants inserted in 67 patients.

Protocol for oral implant rehabilitation in a hemophilic HIV-positive patient with type C hepatitis.

Case Report: A 46-year-old man with severe hemophilia A, stage A2 HIV infection and chronic hepatitis C genotype 1A, for whom the treatment plan included implant-supported prostheses in 2 mandibular edentulous sections. The protocol followed included factor VIII replacement concentrate and oral antifibrinolytic therapy. The right mandibular section was fitted with 3 Straumann implants (Ø 4.

Dental treatment for handicapped patients; sedation vs general anesthesia and update of dental treatment in patients with different diseases.

Dental treatment on Handicapped Patients is often difficult because many people with a wide range of ages (from children to the elderly) with different pathologies that can affect the oral cavity and differ widely are included in this group. This situation creates some controversy, because according to pathology, each patient will be treated differently depending on collaboration, general health status, age or medication used to treat this pathologies. According to this situation we can opt for an outpatient treatment without any kind of previous medication, a treatment under conscious or deep sedation or a under general anesthesia treatment.

Panoramic radiomorphometry and vertebral fractures in Spanish postmenopausal women.

Objective: To evaluate the relationship between panoramic radiomorphometric indexes, and the presence of osteoporotic fractures in a Spanish postmenopausal women.

Methods: A sample of 120 women (60 with fragility spine fractures and 60 healthy), aged 55-70 years, with fragility spine fractures, were included in this cross-sectional study that was conducted from 2008 to 2011. All the women were referred to undergo a radiological spine examination, spinal densitometry and a panoramic radiograph for assessing osteoporosis using 3 radiomorphometric indexes: Panoramic Mandibular Index (PMI), Mental Index (MI) and Mandibular Cortical Index (MCI).

Use of anesthetics associated to vasoconstrictors for dentistry in patients with cardiopathies. Review of the literature published in the last decade.

Objective: The use of local anesthetics associated to vasoconstrictor agents in dentistry is thoroughly justified and is widely extended, but we cannot ignore the fact that anesthetic infiltration poses risk of complications throughout the dental treatment period. The objective of the present review is to document the reported effects the use of the local anesthetics most widely employed in dentistry, with or without association to vasoconstrictor agents may have in patients with any sort of cardiopathy.

Study Design: We have searched for randomized clinical trials on the assessment of the cardiovascular effects of local anesthetics used in dentistry, without limits as regards age or sex, conducted in patients with any type of cardiopathy which were published during the last decade and were index-linked in Cochrane, Embase and Medline.

Cardiovascular effect of dental anesthesia with articaine (40 mg with epinefrine 0,5 mg % and 40 mg with epinefrine 1 mg%) versus mepivacaine (30 mg and 20 mg with epinefrine 1 mg%) in medically compromised cardiac patients: a cross-over, randomized, single blinded study.

Objectives: The aim of the present study is to compare cardiovascular safety profiles of two dental anesthetics: articaine versus two standard mepivacaine solutions used during etiological periodontal treatment in cardiovascular patients.

Study Design: Using a cross-over study design, ten cardiovascular patients were randomly assigned to dental treatment with 1.8 mL of a local anesthetic injected on each quadrant of the mouth: Articaine (40 mg with Epinephrine 0.
