Aim: The purpose of the study was to analyze the healing of the deep and superficial lower first and second molars periodontium, after the surgical extraction of the contiguous impacted third molar, comparing 3 mucoperiosteal flap designs. Materials and methods: 150 patients which had to undergo a impacted lower third molar surgery were enrolled in this study. They were checked from day 0 to day 90, in order to focus on the recovery quality of the soft tissues around the lower second molar, comparing 3 different flap designs...

Objective: To establish a profile of periodontal conditions in chronic kidney disease patients on hemodialysis and their periodontal risk. Methods: We included 115 patients on hemodialysis. Clinical periodontal parameters assessed were: plaque index, gingival index, probing depth and clinical attachment level. Patients were classified according to presence/absence and severity of periodontal disease and periodontal risk. Results: In 107 dentate patients (93%) the plaque index was 1...

Although the fibula free flap (FFF) is a useful choice for mandible reconstruction, its application for large oromandibular defects is still debated upon. We report the use of FFF with a bilobed perforator-based skin paddle for combined hemiglossectomy, floor-of-the-mouth, tonsillar pillar, and mandibular body defect. A case of an 84-year-old woman with a 2.5 × 3.5-cm exophytic ulcerated mass on the right side of the tongue, extended to omolateral gengival fornix, tonsillar pillar, and mandibular body, is reported...

Substance P (SP) is a tachykinin released from both the central and the peripheral endings of primary afferent neurons and functions as a neurotransmitter. As a transmitter signaling pain, substance P is involved in nociception and is an extremely potent vasodilator. We found several studies about this neuropeptide especially in relation to parodontology and a few orthodontic reviews. This is because in the past the importance of this neuropeptide in dental element undergoing periodontal inflammation was observed...

A total of 550 oral streptococci: 270 Streptococcus mitis, 110 Streptococcus sanguis, 90 Streptococcus anginosus, 50 Streptococcus mutans, 30 Streptococcus salivarius, were isolated from dental plaque and gengival crevices of patients and tested for their susceptibility to 12 β-lactam antibiotics and to 5 non-β-lactam antibiotics, using the microdiluition method. Overall, a reduced susceptibility to penicillin was recorded in 13.4% of cases. The percentage of strains resistant to penicillin appeared significantly higher in S...

Oral cavity infection by protozoarian agents may lead to pathologies such as stomatitis and gengivitis. An higher incidence has been reported in immunocompromised patients and in patients with dental disorders. Entoameba gingivalis localizes into oral cavity and in particular into interstitial and interdental spaces. Infection propagation to bronchial or lung parenchyma represents a complication. In this report the Authors, starting from a recently treated case, discuss on the incidence, complications and surgical management of lung infection by Entoameba gingivalis...

The current study assessed trends in oral cancer mortality in the city of São Paulo, Brazil, from 1980 to 2002. The official mortality information system supplied data on deaths whose underlying cause was classified as oral cancer, stratified by sex, age, and anatomic site. Death rates were estimated and adjusted by the direct method, using population data supplied by national censuses from 1980, 1991, and 2000 and a population count performed in 1996. There was an upward trend in overall cancer mortality, at a yearly rate of 0...

AIM: Most of dental operators agree about a gengival retraction impregnated cord in order to obtain an accurate and overwide dental impression. Hemostatic agents allow the formation of the primary coagulum that determines/causes the retraction of gum connective. Sometimes these astringent liquids cause local inflammation reaction as reported in literature. Aim of this work was the evaluation of the cytotoxic and inflammatory action of the most common astringent liquid on human gum primary cells by in vitro tests...

Osteopetrosis is a heterogeneous family of rare human genetic disorders due to markedly decreased bone resorption. It is one among disorders causing osteosclerosis of the trabecular bone and/or hyperostosis of the cortical bone. Four types of human osteopetrosis have been clearly defined, but patients with atypical symptoms are frequent, suggesting that there are additional forms. The most severe expression of this condition in its malignant form is inherited as an autosomal recessive disorder and it is usually fatal before school age...

In the present study the effects of Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) on fibroblast growth and activity have been studied. In this regard the AA have evaluated in primary cultures of human gengival normal fibroblasts (PG1 cells): a)-the expression of GM-CSF receptor (GM-CSFR) (alfa unit) on the cell surface; b)-the in vitro effects of different doses of GM-CSF on the GM-CSFR expression and on the proliferation and activity of fibroblasts. PG1 cells have been stimulated in vitro with different concentrations of GM-CSF (10, 50, 80, 100 and 150 ng/ml) using promonocytic cell line U937 as positive control for GM-CSFR expression...

In order to detect proliferative processes in human marginal gingiva in pathological conditions and after externalization of titanium implants, we have attempted BrdU incorporation after "in vitro" incubation of tissue fragments. In comparison with healthy controls, immunocytochemical detection of samples from patients affected by hypertrophic gengivitis shows a good number of proliferating cells in the basal layer of the epithelium, while only in one case can positiveness be detected after externalization of titanium implants...

The purpose of this clinical study was to value the efficacy of a new mouthwash (Oradyne-Z), with an antiseptic agent, alkyl-dimethyl-benzyl-ammonium-saccarinate, against the formation of bacterial oral plaque, in patients during orthodontic treatment. The test procedure was based on observation of 24 subjects (male and female, aged 14 to 50) and divided into 3 equal groups (group A, B and C) during orthodontic therapy. In six (6) weeks, the first group (A), used Oradyne-Z mouthwash, the second group used a placebo solution (B) ant the third (C), used Chlorhexidine mouthwash...

The purpose of this study was to analyse histomorfologically the X-radiation influence on the chronology of wound healing of tooth extraction. Sixth young albino rats were used. After extracting the maxillary right incisors all the rats, three experimental groups were formed: the control (I) and the groups that received 1.25 Sv (II) and 1.75 Sv (III). The rats were killer at 3, 7, 14 and 28 post-operative days following the teeth extraction. The pieces obtained were submitted to routine laboratorial procedures until getting pieces stained with hematoxylin and eosin...

1. Thirty free autogenous gingival grafts were placed on bone and 30 were placed on a periosteal bed. The distribution into the groups was random. All 60 grafts survived, showing that both procedures were predictable. 2. Over one-half (17 of 30) of those on periosteum demonstrated mobility by 6 months postoperatively. No mobility was observed in the group placed directly on bone. 3. Osseous placed grafts demonstrated less swelling and better hemostasis than did the periosteally placed grafts. 4. A healing lag was observed in the grafts placed on bone which lasted only for the first two postoperative visits, approximately 2 weeks...
