Effect of flap design and duration of surgery on acute postoperative symptoms and signs after extraction of lower third molars: A randomized prospective study.

Different surgical variables are assumed to play a role in postoperative course after lower third molar extraction. The aim of study was to assess whether flap design and duration of surgery can influence acute postoperative symptoms and signs after lower third molar extraction. Twenty-five patients scheduled for lower third molar extraction were included in this study and randomly assigned to two groups in terms of flap design: group A (envelope flap) and group B (triangular flap).

The timing and operational management of the variables of bleaching in cases of rehabilitation in the esthetic field.

Managing esthetic restoration in the presence of discolored teeth is a challenge for both the clinical team and clinician, whose aim is to use methods that are as minimally invasive as possible, and materials that allow the preservation of dental tissue. Should one wish to act on the discoloration of teeth that are to be restored, or on adjacent ones, it becomes essential to take action on dental tissues. This is done through bleaching and dental restoration, using materials that allow various clinical situations to be managed, such as those with different tonalities between the teeth: prosthetic materials that offer adequate uniformity in their results in those areas where it is necessary to mask the discoloration.

Explaining pain after lower third molar extraction by preoperative pain assessment.

Purpose: To evaluate whether preoperative pain sensitivity testing and emotional perception of pain could explain the level of postoperative pain after lower third molar extraction.

Patients And Methods: Twenty-three patients (16 women, 7 men) scheduled for lower third molar extraction were enrolled in the study. Patients preoperatively were submitted to a nociceptive stimulus by a cold pressor test (immersion of the hand into ice water).

Interleukin-1 beta levels in gingival crevicular fluid and serum under naturally occurring and experimentally induced gingivitis.

Aims: To evaluate the interleukin-1 beta (IL-1 beta) levels in gingival crevicular fluid (GCF) and serum in either naturally occurring (N-O) or experimentally induced (E-I) plaque-associated gingivitis.

Material And Methods: Thirty-seven periodontally healthy subjects were evaluated in real life conditions (N-O gingivitis) as well as after 21 days of experimental gingivitis trial (E-I gingivitis). During the experimental gingivitis trial, in one maxillary quadrant (test quadrant), gingival inflammation was induced by oral hygiene abstention, while in the contralateral (control) quadrant, oral hygiene was routinely continued.

Milled bar-supported implant overdenture after mandibular resection: a case report.

After surgical treatment for oral cancer, patients often are affected by disfigurements, thwarted function, and psychological and social problems. Prosthodontic rehabilitation has the aim of restoring function and esthetics. Implant-supported prosthodontic rehabilitation is useful for patients with compromised residual ridge anatomy, such as patients with oral cancer following treatment.

Influence of obstetric factors on osteogenic potential of umbilical cord-derived mesenchymal stem cells.

Wharton's jelly from the umbilical cord is a noncontroversial source of mesenchymal stem cells (WJMSCs) with high plasticity, proliferation rate and ability to differentiate towards multiple lineages. WJMSCs from different donors have been characterized for their osteogenic potential. Although there is large evidence of WJMSCs plasticity, recently scientific debate has focused on MSCs selection, establishing predictable elements to discriminate the cells with most promising osteoprogenitor cell potential.

Implant-prosthetic rehabilitation for a patient with monolateral cleft lip and palate: a clinical report.

Cleft lip and palate (CLP) is a malformation of genetic derivation. For patients affected by CLP, procedures of guided bone regeneration by autologous bone grafting are recognized as the most effective to close oronasal communication. The residual gap of alveolar ridge, determined by the absence of 1 or more permanent teeth, can be completed by implant-prosthetic rehabilitation.

Single-flap approach with buccal access in periodontal reconstructive procedures.

Background: New surgical techniques have been developed to optimize primary closure as well as to minimize the surgical trauma in the reconstructive procedures of periodontal intraosseous defects. Recently, we proposed a minimally invasive procedure, the single-flap approach (SFA), specifically indicated when the defect extension is prevalent on the buccal or oral side. The basic principle of the SFA is the elevation of a flap to access the defect only on one side (buccal or oral), leaving the opposite side intact.

GBR and autogenous cortical bone particulate by bone scraper for alveolar ridge augmentation: a 2-case report.

Scientific literature describes autogenous bone as the gold standard among graft materials for alveolar reconstructive procedures. Alveolar ridge augmentation has been clinically achieved with different forms of autogenous bone, including autogenous cortical bone particulate (ACBP). However, few histologic studies demonstrating the biologic potential and healing dynamics following the use of ACBP are currently available.

Time as a factor in the identification of subjects with different susceptibility to plaque-induced gingivitis.

Objectives: The purpose of this study was to assess whether identification of subjects with different susceptibility to plaque-induced gingival inflammation is dependent on the length of time of de novo plaque accumulation.

Methods: Retrospective analysis of data obtained from a recently reported randomized split-mouth localized experimental gingivitis trial involving 96 healthy non-smokers. Gingival and plaque index, gingival crevicular fluid volume (GCF), angulated bleeding score, and the derived parameter cumulative plaque exposure (CPE) were recorded at days 0, 7, 14, and 21.

Alveolar ridge augmentation: a comparative longitudinal study between calvaria and iliac crest bone grafrs.

Insertion of endosseous implants is often difficult because of lack of supporting bone. In the case of severe atrophy of the jaws, a large volume of autogenous bone can be harvested from the iliac crest and calvaria. Both grafts undergo partial resorption with time, but the rate of bone loss has not been fully elucidated.
