INTRODUCTION: The periodontal morphotype is a leading feature to be born in mind during surgical, implant, prosthetic, restorative as well as orthodontic treatment. A fragile morphotype will rapidly trigger severe and worrying clinical repercussions for the patient. MATERIALS AND METHODS: In order to minimize the risks involved, sound knowledge of the different morphotypes and of the techniques for clinically evaluating them is a major requirement. These factors need to be regularly reassessed since morphotypes can vary throughout the course of treatment...

INTRODUCTION: The study examines how the shape of the teeth is taken into account in the context of facial hyperdivergency. One aim was to check out the widely-held belief that the hyperdivergent patient has long teeth. DISCUSSION: Our study found no link between the shape of the teeth and facial hyperdivergency, thus confirming the results in the literature. We examined the issue of how to characterize dental shapes. We found three diversely-appreciated types of shape: rectangular, triangular and ovoid...

INTRODUCTION: The extraction-non extraction dilemma is a classic one in the history of orthodontics [2, 19, 30]. In some cases the decision seems to be very clear whereas in some others discrepancies among clinicians can easily be found. Different authors propose different protocols in order to decide whether extractions are necessary in a particular clinical situation. In the last 25 years, the debate has been reframed with new non-extractionists trends based on new treatment philosophies or mechanics...

We report the case of a 65-year-old man presenting with generalised seizures after developing a right frontal brain abscess. Stereotactic aspiration and subsequent matrix assisted laser desorption/ionisation time-of-flight analyzer (MALDI-TOF) spectrometry revealed Porphyromonas gingivalis as the only causative anaerobe microorganism. Secondary incision and drainage was required due to neurological deterioration with increased dimensions of the abscess, intracranial pressure and formation of a subdural occipitoparietal empyema...

Orthodontic force simulation is very important for the guidance of clinical orthodontic treatment. Previous works were mainly conducted by directly loading the force on a single or a few teeth. However, in clinic, the orthodontic force is provided by loading orthodontic appliances, and there currently is no appropriate way to measure the force on the teeth provided by the loaded appliances. This study presents a method to simulate the orthodontic force of a whole Tooth-Periodontal Ligament-Bone Complex (TPBC) by directly loading the archwire to the dentition applying the finite element method...

We present a system for estimating the dental plaque adhesion area using a commercial camera image for oral healthcare via management of the intraoral environment. In recent years, several studies have reported on the relationship between a general disease and a periodontal disease. Such studies mention that normalization of the intraoral environment by tooth brushing is the most important treatment in preventive dentistry. However, evaluation of individual tooth brushing skill is difficult. Some devices for automatically measuring the quantity of dental plaque have already been proposed for the teaching tool of tooth brushing...

OBJECTIVE: To estimate the association between osteoporosis treatment and severe periodontitis in postmenopausal women. METHODS: This cross-sectional study comprised of 492 postmenopausal women, 113 women in osteoporosis treatment, and 379 not treated. Osteoporosis treatment consisted of systemic estrogen alone, or estrogen plus progestin, and calcium and vitamin D supplements, for at least 6 months. Severe periodontitis was defined as at least two interproximal tooth sites with clinical attachment loss of at least 6 mm, and at least one interproximal site with probing depth of at least 5 mm; and dental caries experience was measured using the decayed, missing, and filled teeth (DMFT) index...

In-situ forming implants (ISFI) offer an interesting potential for the treatment of periodontitis, allowing for time-controlled drug release directly at the site of action (which is difficult to reach). For this purpose, ISFI loaded with antibiotics have been reported in the literature. But the use of antibiotic drugs at low doses over prolonged periods of time can lead to the development of bacterial resistances. This risk should be avoided. The aim of this study was to develop a novel type of in-situ forming implants, loaded with the antiseptic drug chlorhexidine...

Veterinary dentistry has tended to follow the trends and advancements in the human dental field. As for any procedure performed on a patient, whether human or animal, an informed decision is based on the available evidence regarding treatment options. This is certainly true for the more involved treatments in veterinary dentistry which can include the disciplines of endodontics and dental implantology. A number of published case reports have been accepted by the specialty that endodontic therapy is indeed a predictable and a valuable service that can be offered to pet owners...

AIMS: Several materials have been introduced as bone grafts, i.e., autografts, allograft, xenografts, and alloplastic grafts, and studies have shown them to produce greater clinical bone defect fill than open flap debridement alone. The aim of this clinical and radiological 6-month study was to compare and evaluate the clinical outcome of deep intraosseous defects following reconstructive surgery with the use of mineralized cancellous bone allograft (Puros(®)) or autogenous bone. MATERIALS AND METHODS: Ten patients with 12 sites exhibiting signs of moderate generalized chronic periodontitis were enrolled in the study...

BACKGROUND: Aggregatibacter actinomycetemcomitans is an etiological agent of both chronic and aggressive periodontitis. Dissemination of A. actinomycetemcomitans from the oral cavity and initiation of systemic infections has led to new approaches for treatment being needed. In this study, a series of experiments presented investigated the effect of methylene blue (MB)-mediated antimicrobial photodynamic therapy (aPDT) on cell viability and expression of fimbria-associated gene (rcpA) in A...

BACKGROUND: Wound-related infection remains a major challenge for health professionals. One disadvantage in conventional antibiotics is their inability to penetrate biofilms, the main protective strategy for bacteria to evade irradiation. Previously, we have shown that synthetic antimicrobial peptides could inhibit bacterial biofilms formation. RESULTS: In this study, we first delineated how Nal-P-113, a novel antimicrobial peptide, exerted its inhibitory effects on Porphyromonas gingivalis W83 biofilms formation at a low concentration...

Hyposalivation contributes to dental caries, periodontitis, and microbial infections. Additionally, it impairs activities of daily living (e.g., speaking, chewing, and swallowing). Treatments for hyposalivation are currently limited to medications (e.g., the muscarinic receptor agonists pilocarpine and cevimeline) that induce saliva secretion from residual acinar cells and the use of saliva substitutes. However, given that these therapies provide only temporary relief, the development of alternative treatments to restore gland function is essential...

AIM: We have previously shown that the secreted glycoprotein MFG-E8 has anti-inflammatory and anti-osteoclastogenic properties. Our objective was to investigate the potential of MFG-E8 as a diagnostic or therapeutic agent in periodontitis. MATERIALS AND METHODS: Periodontitis was induced in non-human primates (NHPs) by placing ligatures around posterior teeth on both halves of the mandible for a split-mouth design: one side was treated with MFG-E8-Fc and the other with Fc control...

The rich bacterial flora of oral cavity is controlled by innate immune response, including antibacterial peptides and among them human neutrophil peptides 1-3 (HNP1-3). The knowledge of the involvement of HNPs in innate and acquired immunity of the periodontium is fragmentary. The aim of the study was to assess alterations in HNP1-3 levels in the gingival crevicular fluid (GCF) of chronic periodontitis patients before and after nonsurgical periodontal therapy. Nineteen patients with chronic periodontitis were qualified to the study...
