Abstract
BACKGROUND AND OBJECTIVE The aim of this interventional, parallel-assignment, single-blinded, randomized, efficacy study was to investigate the efficacy of the treatment of gingival recessions by osteogenic cell transfer. This is the first randomized clinical trial of this nature. MATERIAL AND METHODS Treatment of Miller class I or II gingival recessions >4 mm was randomly defined by casual sorting and performed by newly forming bone graft (NFBG) and coronally advanced flap (CAF) or subepithelial connective tissue graft (SCTG) and CAF (control). Clinical examinations were performed by a single blinded examiner at baseline and at 3, 6, and 9 months after surgery. Parameters investigated were recession height (REC), probing depth (PD), clinical attachment level, gingival bleeding index (GBI), plaque index (PlI), and keratinized gingiva width (KGW). RESULTS Both techniques achieved similar percentage of root coverage, but NFBG was more effective in pocket depth reduction, attachment level gain, and reduction of plaque accumulation and of bleeding on probing. CONCLUSIONS These findings suggest that the transfer of osteogenic cells by NFBG is able to improve clinical attachment level and to cover denuded roots. NFBG can be used as an alternative treatment of deep recessions (≥4 mm), where the restoration of lost periodontal tissues is intended.

Abstract
BACKGROUND AND OVERVIEW The aim of this study was to describe the effects of bruxism in peri-implant bone loss 6 years after the placement of a successful implant-supported prosthesis, to describe its treatment, and to propose a differential diagnosis of the lesion. CASE DESCRIPTION A 62-year-old, nonsmoking, systemically healthy partially edentulous woman received 2 osseointegrated implants in the mandibular left region, which supported a 3-element fixed prosthesis. Six years later, the patient reported the development of bruxism. Clinical examination results indicated bleeding on probing, deepening of the peri-implant sulcus, and marginal soft-tissue overgrowth. Radiographic images suggested peri-implant bone loss. The authors diagnosed the lesion as trauma from occlusion and mucositis. Treatment involved anti-infective therapy and the use of a bite platform, resulting in bone recovery after 10 months. These results were maintained for 4 years. CONCLUSIONS AND PRACTICAL IMPLICATIONS Considering the existing contradictions in the literature, this case highlights the role of trauma from occlusion in the onset, progression, and treatment of lesions produced by occlusal overload around osseointegrated implants. In addition, it provides clinical background on the outcomes of anti-infective therapy associated with the use of a bite platform in the treatment of combined lesions of mucositis and trauma from occlusion in osseointegrated implants.

Abstract
BACKGROUND Autologous bone grafts are usually well consolidated after 4 to 5 months but can be incompletely interlocked with the native bone. This study investigated the effect of acid demineralization of the graft-bed interface on graft consolidation. METHODS Onlay bone grafts were performed on the calvaria of 36 guinea pigs. Half of the animals had the graft-bed contacting surfaces demineralized with 50% citric acid (pH 1.0) for 3 minutes (test group). The other half received no demineralization (control group). The bone grafts were immobilized by a resorbable membrane glued to the recipient bed with cyanoacrylate. After 7, 30, and 90 days, specimens (n = 6) were obtained for light microscopy. Data from qualitative analysis and computerized histomorphometry were statistically processed at a significance level of 5%. RESULTS Osteogenesis was not seen at the interface after 7 days. After 30 days, the test group showed 34.39% ± 13.4% of the interface area filled with mineralized tissue, compared to 17.14% ± 8.6% in the control group (P = 0.026). After 90 days, the mean percentages of mineralized tissue at the interface in the test and control specimens were 54.00% ± 11.23% and 38.65% ± 7.76% (P = 0.041), respectively. Within groups, a higher percentage of the area filled with mineralized tissue was seen at 90 days compared to 30 days (P = 0.004 for control and 0.041 for test). CONCLUSIONS Demineralization of the contacting surfaces between autologous bone graft and bone bed improved new bone formation and bone consolidation. These data need to be confirmed in humans.

Abstract
The gingival recession was assessed in 380 adult individuals aged more than 20 years and comprised both subjects being treated and looking for treatment at Bauru Dental School. Clinical evaluation was conducted by a single examiner in all teeth and involved analysis of four dental aspects (mesial, buccal, distal and lingual). The gingival recession was regarded as present whenever more than 1mm of root surface was exposed, and its vertical width was measured in millimeters from the cementoenamel junction to the gingival margin. The recessions were further scored following the criteria suggested by Miller in 1985. Gingival recession was observed in at least one dental surface in about 89% of the individuals analyzed. The prevalence, extension and severity of this clinical aspect increased with age. Class I recessions were the most frequent, yet there was a gradual increase of Class III and IV recessions as older subjects were evaluated. The mandibular teeth displayed more surfaces with gingival recession than the maxillary teeth and the mandibular incisors were the most affected teeth. Such high prevalence of gingival recession in adult patients demonstrates that dental professionals should provide attention to the clinical relevance of such alterations, as well as to the diagnosis of the etiologic factors.

Abstract
The purpose of this study was to evaluate the effect of the pool of bovine BMPs on the treatment of intrabony defects. The sample comprised 15 patients aged 26 to 57 years old presenting with 10 pairs of lesions of 2 or 3 walls or 2-3 walls ³5mm, located in the same type teeth (premolar or molar) and same jaw. The test defects were treated with combination of a pool of bovine bone morphogenetic and resorbable hydroxyapatite carrier (BMPs- HA), bovine demineralized bone matrix (MB) and coverage by a bovine collagen barrier membrane. The control defects were treated with MB-HA and covered by a bovine collagen membrane. The clinical measurements at six months after therapy in the test group revealed a reduction in the mean probing pocket depth (PPD) of 1.63 ± 1.41mm (B) and 1.93 ± 0.96mm (L) and a mean change in the clinical attachment level (CAL) of 1.60 ± 1.16mm (B) and 1.46 ± 0.97mm (L). The control group showed a mean reduction of PPD of 1.93 ± 1.34mm (B) and 2.0 ± 1.51mm (L) and a mean change of CAL of 1.03 ± 1.24mm (B) and 1.30 ± 1.14 mm (L). The analysis of variance (ANOVA) demonstrated that the changes in the clinical parameters were statistically significant (p<0.05). There were no significant differences between the test and controls subjects (Student's test, p<0.005). These findings suggest that the use of a pool of bovine BMPs do not provide added effects to GTR in the treatment of intrabony defects.

Abstract
UNLABELLED Most studies investigating the impact of oral contraceptives have been performed some years ago, when the level of sexual hormones was greater than the actual formulations. OBJECTIVE The aim of this study was to evaluate the effects of current combined oral contraceptives (COC) on periodontal tissues, correlating the clinical parameters examined with the total duration of continuous oral contraceptive intake. MATERIAL AND METHODS Twenty-five women (19-35 years old) taking combined oral contraceptives for at least 1 year were included in the test group. The control group was composed by 25 patients at the same age range reporting no use of hormone-based contraceptive methods. Clinical parameters investigated included pocket probing depth (PD), clinical attachment level (CAL), sulcular bleeding index (SBI) and plaque index (Pl.I). Data were statistically evaluated by unpaired t test, Pearson's correlation test and Spearman's correlation test. RESULTS The test group showed increased PD (2.228±0.011 x 2.154±0.012; p<0.0001) and SBI (0.229±0.006 x 0.148±0.005, p<0.0001) than controls. No significant differences between groups were found in CAL (0.435±0.01 x 0.412±0.01; p=0.11). The control group showed greater Pl.I than the test group (0.206±0.007 x 0.303±0.008; p<0.0001). No correlation between the duration of oral contraceptive intake, age and periodontal parameters was observed. CONCLUSIONS These findings suggest that the use of currently available combined oral contraceptives can influence the periodontal conditions of the patients, independently of the level of plaque accumulation or total duration of medication intake, resulting in increased gingival inflammation.

Abstract
UNLABELLED Many techniques have been proposed for root coverage. However, none of them presents predictable results in deep and wide recessions. OBJECTIVES The aim of this case series report is to describe an alternative technique for root coverage at sites showing deep recessions and attachment loss >4 mm at buccal sites. MATERIAL AND METHODS Four patients presenting deep recession defects at buccal sites (>4 mm) were treated by the newly forming bone graft technique, which consists in the creation of an alveolar socket at edentulous ridge and transferring of granulation tissue present in this socket to the recession defect after 21 days. Clinical periodontal parameters, including recession depth (RD), probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), plaque index (PI) and keratinized gingiva width (KGW) were evaluated by a single examiner immediately before surgery and at 1, 3, 6 and 9 months postoperatively. RESULTS All cases showed reduction in RD and PD, along with CAL gain, although no increase in KGW could be observed. These findings suggest that the technique could favor periodontal regeneration along with root coverage, especially in areas showing deep recessions and attachment loss.

Abstract
UNLABELLED Dental roots that have been exposed to the oral cavity and periodontal pocket environment present superficial changes, which can prevent connective tissue reattachment. Demineralizing agents have been used as an adjunct to the periodontal treatment aiming at restoring the biocompatibility of roots. OBJECTIVE This study compared four commonly used demineralizing agents for their capacity of removing smear layer and opening dentin tubules. METHODS Fifty fragments of human dental roots previously exposed to periodontal disease were scaled and randomly divided into the following groups of treatment: 1) CA: demineralization with citric acid for 3 min; 2) TC-HCl: demineralization with tetracycline-HCl for 3 min; 3) EDTA: demineralization with EDTA for 3 min; 4) PA: demineralization with 37% phosphoric acid for 3 min; 5) CONTROL: rubbing of saline solution for 3 min. Scanning electron microscopy was used to check for the presence of residual smear layer and for measuring the number and area of exposed dentin tubules. RESULTS Smear layer was present in 100% of the specimens from the groups PA and control; in 80% from EDTA group; in 33.3% from TC-HCl group and 0% from CA group. The mean numbers of exposed dentin tubules in a standardized area were: TC-HCl=43.8±25.2; CA=39.3±37; PA=12.1±16.3; EDTA=4.4±7.5 and CONTROL=2.3±5.7. The comparison showed significant differences between the following pairs of groups: TC-HCl and CONTROL; TC-HCl and EDTA; CA and CONTROL; and CA and EDTA. The mean percentages of area occupied by exposed dentin tubules were: CA=0.12±0.17%; TC-HCl=0.08±0.06%; PA=0.03±0.05%; EDTA=0.01±0.01% and CONTROL=0±0%. The CA group differed significantly from the others except for the TC-HCl group. CONCLUSION There was a decreasing ability for smear layer removal and dentin tubule widening as follows: AC>TC-HCl>PA>EDTA. This information can be of value as an extra parameter for choosing one of them for root conditioning.

Abstract
Objective. To shed light on the role of KG, its influence on periodontal behavior was investigated. Methods. Tissue fluid transudation was assessed in alveolar mucosa (P1A), outer gingival margin (P1B), at entrance of (P2) and within gingival sulcus (P3), before and after chewing of fibrous food in 16 patients portraying ≥2 mm KG at one tooth (group 1), and <2 mm at another homologous tooth (group 2). Results. There was a significant increase in GCF after chewing at P1B and P3 in group 1 and at P1A in group 2 (t-test, P < 0.05). Conclusions. The results suggest that KG plays a role in marginal periodontal homeostasis.

Abstract
Objectives The aim of this study was to evaluate the effects of non-surgical treatment of
periodontal disease during the second trimester of gestation on adverse pregnancy
outcomes. Material and Methods Pregnant patients during the 1st and 2nd trimesters at
antenatal care in a Public Health Center were divided into 2 groups: NIG – "no
intervention" (n=17) or IG- "intervention" (n=16). IG patients were submitted to a
non-surgical periodontal treatment performed by a single periodontist consisting
of scaling and root planning (SRP), professional prophylaxis (PROPH) and oral
hygiene instruction (OHI). NIG received PROPH and OHI during pregnancy and were
referred for treatment after delivery. Periodontal evaluation was performed by a
single trained examiner, blinded to periodontal treatment, according to probing
depth (PD), clinical attachment level (CAL), plaque index (PI) and sulcular
bleeding index (SBI) at baseline and 35 gestational weeks-28 days
post-partum. Primary adverse pregnancy outcomes were preterm
birth (<37 weeks), low birth weight (<2.5 kg), late abortion (14-24 weeks)
or abortion (<14 weeks). The results obtained were statistically evaluated
according to OR, unpaired t test and paired t test at 5% significance level. Results No significant differences were observed between groups at baseline examination.
Periodontal treatment resulted in stabilization of CAL and PI (p>0.05) at IG
and worsening of all periodontal parameters at NIG (p<0.0001), except for PI.
Significant differences in periodontal conditions of IG and NIG were observed at
2nd examination (p<0.001). The rate of adverse pregnancy
outcomes was 47.05% in NIG and 6.25% in IG. Periodontal treatment during pregnancy
was associated to a decreased risk of developing adverse pregnancy outcomes
[OR=13.50; CI: 1.47-123.45; p=0.02]. Conclusions Periodontal treatment during the second trimester of gestation contributes to
decrease adverse pregnancy outcomes.

Abstract
AIM To investigate into oral health status and its association with health status in hospitalized patients. METHODS A total of 82 patients were examined and 49 (59.7%) patients were men. The patients answered a survey and oral examinations to detect the number of teeth, oral hygiene index, prostheses hygiene, oral lesions, caries, dental plaque index (DPI), gingival inflammation index (GI), gingival bleeding index, periodontitis and periodontal index. RESULTS Oral hygiene was associated with age, but it was not related to physical disability. Difficulty eating was mainly associated with age and tooth loss. All full and partially dentate patients presented dental plaque, 38 (69%) poor oral hygiene, 58 (98.1%) gingival inflammation, 41 (74.5%) periodontal disease and 33 (60%) caries. Oral lesions were detected in 30 (36.5%) and candidiasis (n = 16, 19.6%) was the most frequent mucous lesion. Caries were associated with smoking and poor oral hygiene. Hospital length of stay and age were associated with increased DPI and GI. CONCLUSIONS The majority of hospitalized patients did not present satisfactory oral hygiene. Caries and periodontal diseases are associated with health behaviours. Increased time length at hospital could increase gingival inflammation and dental plaque accumulation.

Abstract
Objectives This study assessed the bone density gain and its relationship with the
periodontal clinical parameters in a case series of a regenerative therapy
procedure. Material and Methods Using a split-mouth study design, 10 pairs of infrabony defects from 15 patients
were treated with a pool of bovine bone morphogenetic proteins associated with
collagen membrane (test sites) or collagen membrane only (control sites). The
periodontal healing was clinically and radiographically monitored for six months.
Standardized presurgical and 6-month postoperative radiographs were digitized for
digital subtraction analysis, which showed relative bone density gain in both
groups of 0.034 ± 0.423 and 0.105 ± 0.423 in the test and control
group, respectively (p>0.05). Results As regards the area size of bone density change, the influence of the therapy was
detected in 2.5 mm2 in the test group and 2 mm2 in the
control group (p>0.05). Additionally, no correlation was observed between the
favorable clinical results and the bone density gain measured by digital
subtraction radiography (p>0.05). Conclusions The findings of this study suggest that the clinical benefit of the regenerative
therapy observed did not come with significant bone density gains. Long-term
evaluation may lead to a different conclusions.

Abstract
Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for non-smokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine's vasoconstrictor effect.

Abstract
The purpose of this study was to evaluate histologically the root surfaces of teeth submitted to orthodontic and surgical extrusion procedures in a dog model. Eighteen adult male dogs, divided into six groups of three dogs each, were used in the study. Each animal underwent two procedures: rapid orthodontic extrusion and surgical extrusion of the maxillary lateral incisors. The animals were sacrificed to produce samples at 7, 14, 45, 90, 120, and 180 days after surgery for assessment of cross sections of the coronal, medial, and apical thirds of the treated teeth. At early time points, some active surface and inflammatory resorption was observed exclusively in the surgical extrusion group; however, samples collected at later times demonstrated functional repair of the resorption gaps in both groups. Ankylosis was observed as a minor event and was apparently of a transient nature in samples of the surgical extrusion group. The results demonstrate the importance of maintaining the periodontal ligament and cementum surface; both are vital for the prevention of root resorption. It may be postulated that orthodontic extrusion is more conservative and physiologic than surgical extrusion; however, the results showed that function was restored in both groups.

Abstract
BACKGROUND A new fibrin adhesive made of buffalo plasma-derived fibrinogen and a thrombin-like snake venom enzyme, has been successfully used to immobilize free gingival grafts. This case series histologically compared sutured grafts (control group) with others immobilized by using the fibrin adhesive (experimental group). CASE DESCRIPTION The grafts were placed in the contralateral mandibular bicuspids of 15 patients, so that each subject received one treatment of each type. Five biopsies of each group were collected at 7, 14 and 45 days of healing, which were histologically and morphometrically analyzed as regards the relative volume density of the different connective tissue components. RESULTS The sites in the control group presented a higher inflammatory cell density at 7 days and a tendency towards a lower collagen density. In the experimental group, the grafts had an appearance of more advanced healing. Tissue maturity characteristics progressed until 14 and 45 days, but no difference between groups could be noted at these times. CONCLUSIONS Within the limits of the present study, it may be suggested that the alternative fibrin adhesive tested could represent an alternative to sutures in gingival grafts procedures.

Abstract
This article reports the longitudinal follow-up of a familial case of aggressive periodontitis treated by a combined regenerative approach that consisted of root conditioning, bone grafting, and membrane positioning. Treatment resulted in attachment level gain, reduction of probing depth, absence of bleeding on probing, and complete bone filling of the defect. The short-term results obtained after surgery were maintained after 6 years, suggesting that the combined regenerative approach is able to completely arrest the disease with long-term stability.

Abstract
BACKGROUND A new fibrin adhesive made of buffalo plasma-derived fibrinogen and a thrombin-like enzyme obtained from snake venom was evaluated in this case series with regard to its applicability in periodontal surgery. Free gingival grafts that were sutured (control group) were compared to others immobilized through the use of the adhesive (experimental group). METHODS The grafts were carried out in contralateral mandibular bicuspids of 15 patients so that each subject received one treatment of each type. The analysis included measurements of probing and vertical dimension of the grafts and photographic follow-up for 90 days. The patients answered a questionnaire concerning postoperative signs and symptoms. RESULTS The decrease in the vertical dimension of the grafts was significant during the first 30 days and more dramatic for the control group. Probing depth and attachment level presented statistically significant decreases for both groups. The grafts of the experimental group presented better appearance during the first 14 postoperative days. Pain was observed more often in the control group. CONCLUSIONS Within the limits of the present study, it is suggested that the alternative fibrin adhesive tested may represent an alternative to sutures in periodontal surgery. Nevertheless, randomized clinical trials should be performed to evaluate the clinical advantages and disadvantages of the material.

Abstract
BACKGROUND This case series reports on the effectiveness of the modified apically repositioned flap (MARF) in increasing the apico-coronal dimension of attached gingiva over multiple adjacent teeth. METHODS The MARF surgical technique consists of a single horizontal incision within keratinized tissue, elevation of a split-thickness flap, and suturing of the flap to the periosteum in an apical position. The periosteum is left exposed so that the full perimeter of the wound is surrounded by keratinized tissue. The nature of this wound healing leads to the formation of new keratinized and attached tissue in the area where periosteum is left exposed. A total of 37 areas in 33 systemically healthy patients were analyzed after treatment with the MARF technique. The treatment areas consisted of a minimum of two and a maximum of five adjacent teeth with a minimum of 0.5 mm and a maximum of 2.0 mm of attached gingiva on each tooth. RESULTS Treatment with MARF resulted in a significant increase in the apico-coronal dimension of the keratinized tissue and attached gingiva (P <0.05). The increase in keratinized tissue ranged from 2.20 to 4.28 mm, and the increase in attached gingiva ranged from 1.0 to 3.14 mm. Gingival recession decreased significantly in the treated areas, but the difference was of little clinical significance. Probing depths in the treated areas did not change significantly compared to baseline values. CONCLUSIONS MARF is an effective technique in increasing the apico-coronal dimension of the keratinized tissue and attached gingiva. MARF offers considerable advantages over other mucogingival surgery techniques: simplicity, limited chair time for the patient and the operator, low morbidity because of the absence of palatal donor tissue, and a predictable tissue color match.

Abstract
What can be done for a 17-year-old girl with localized juvenile periodontitis, a Class II malocclusion, and flared teeth? Is it possible to regain epithelial attachment and rebuild the bone architecture? Is it possible to achieve good esthetics and occlusion with conventional orthodontic treatment, or is an interdisciplinary approach needed? What sequence should be followed? What is the prognosis for the affected teeth in the long term? Our aim in this article was to review the literature and present a clinical case to shed more light on the subject.

Abstract
Epidemiology is the study of health and disease in populations, and of how these conditions are influenced by heredity, biology, physical environment, social environment, and personal behavior. There are many epidemiological studies in Brazilian population but few about the influence of some risk factors in periodontal conditions. This cross-sectional study was performed to assess the influence of age, sex, plaque and smoking on periodontal disease in a population from Bauru (Brazil). Data concerning periodontal status were collected from 380 patients in the University of São Paulo (USP). Measurements of periodontal pocket depths (PPD), clinical attachment levels (CAL), plaque index (PI) of four sites in all teeth were registered. The influence of age, sex and smoking habits on the periodontal parameters were statistically evaluated using descriptive statistical and ANOVA. The correlation between plaque and periodontal parameters was analyzed by Pearson's correlation coefficient. The results showed an increase in the mean of periodontal destruction (PPD and CAL) and a higher number of sites with severe losses with increasing age. Correlation among percentage of sites with plaque and periodontal parameters (PPD and CAL) were positive but weakly related. The male group showed significantly higher means of CAL than the female. Smokers had significantly higher PPD and CAL means than non-smokers. Aging, smoking habit, male sex, and percentage of sites with plaque were associated with a great increase of periodontal destruction, being important factors in the diagnosis of the periodontal disease in this Brazilian population.

Abstract
Low-intensity laser therapy aims at pain suppression, edema reduction and acceleration of wound healing. The main goal of this study was to clinically evaluate the effects of Aluminum Gallium Arsenate laser - 670nm in wound healing after gingivoplasty in 11 patients. Surgery was performed in anterior superior and/or inferior regions. The right side of the patient (test group) received a laser energy density of 4J/cm², in a 48-hour interval, during one week, totalizing four sessions. The irradiation was punctual in a contact mode in three points. The left side did not receive irradiation (control group). Clinical evaluation was performed by five specialists in periodontology through photography of the treated areas at post-surgical periods of 7, 15, 21,30,60 days. The observers pointed the best healed side. The Sign test was used for statistical analysis with a confidence level of 5% (P<0.05). The examiners found a better pattern of healing sometimes in the test and sometimes in the control group until 21 days after surgery. After this period there was no apparent difference between them. There was no statistical difference between the sides (p>0.05). These results have shown that low-intensity laser therapy did not accelerate oral mucosa healing after gingivoplasty.

Abstract
A modification of the surgical extrusion technique to treat fractured teeth was realized as an alternative periodontal therapy to avoid ostectomy following orthodontic extrusion of teeth with their biologic widths compromised by different etiologic involvements. After delicate luxation and arrested avulsion, the teeth were coronally positioned to allow room for a new biologic width. Clinical and radiographic monitoring showed the ability of the periodontium to adapt function and esthetic recovery. The advantages and disadvantages of this therapeutic procedure for resolution of a periodontal involvement are presented.

Abstract
BACKGROUND AND OBJECTIVES The aim of the present study was to analyze the effects of diode laser irradiation on the healing of human oral mucosa. MATERIALS AND METHODS After gingivoplasty, the right hemi-arch (test group) of 16 patients was irradiated with a diode laser. The left side (control group) was not irradiated. Incisional biopsies were performed on both sides at 7, 14, 21, and 60 days after surgery and morphometrically analyzed by light microscopy. RESULTS Epithelium width ranged from 260.6 to 393.5 microm. Volume densities of basal (20.2%), prickle cell (55.6%), and cornified (24.2%) layers remained stable. The peak number of neutrophils were 6 cells/mm(2) and the mononuclear cells were 44 cells/mm(2). Collagen fibers (80%) and fibroblasts (14%) occupied the main volume of connective tissue. The one-way ANOVA and the paired Student's t-test were used for statistical analysis (P < 0.05). CONCLUSION Low-level laser therapy did not accelerate the healing of oral mucosa after gingivoplasty.

Abstract
The aim of this study was to assess the periodontal condition and the presence of putative periodontal pathogens in 30 Brazilian mothers, aging 21-40 years (28.4 4.49 years), and in their children, aging 5-6 years, since mothers can be a source of pathogens and, thus, influence their children's bacteriological and clinical condition. Besides assessing the plaque index (PI), gingival index (GI) and pocket probing depth (PD), the survey analyzed four subgingival dental plaque samples from mothers and children, as well as a sample of stimulated saliva from mothers. Those samples were analyzed by means of the slot immunoblot (SIB) technique, in order to determine the presence of Actinobacillus actinomycetemcomitans (Aa), Prevotella nigrescens (Pn), Porphyromonas gingivalis (Pg) and Treponema denticola (Td). The mean values and standard deviations of the evaluated clinical variables for mothers and children were, respectively: 1.86 0.67 and 1.64 0.68 for PI, and 1.24 0.67 and 0.82 0.37, for GI. Only for mothers, the total PD was 1.81 0.69 mm, and the PD of four sites was 4.03 1.40 mm. The Wilcoxon test revealed significant difference (p < 0.05) between mothers and their children only as to GI. The most prevalent bacteria in mothers were, in decreasing order: Aa, Pn, Pg and Td. The children presented patterns of oral hygiene and bacterial profiles similar to those of their mothers, in spite of the fact that most of them did not present enough subgingival plaque for testing. The comparison between mothers' subgingival dental plaque and saliva samples revealed statistically significant differences (p < 0.05) for all bacteria, with greater positivity and scores in the saliva, which demonstrates that it is an indicator of oral colonization and can work as a vehicle for the transmission of periodontopathogens from mothers to their children.

Abstract
The interproximal plaque-removing effect of three different materials (classic dental floss, rafia floss and indian floss) was tested in a group of 80 males (18 years-old). After two weeks all the materials had the same efficacy in removing the bacterial plaque, with significant reduction in interproximal plaque index. According to an opinion inquiry the rafia floss was the most comfortable material to use and has the lowest cost as well.

Abstract
Thirty photoelastic dental-periodontal patterns were prepared according to the following criteria: ten with cilindrical shaped roots (series I), ten with conical shaped roots from apical do cervical (series II), ten with conical shaped roots from cervical to apical (series III), all of them having the same superficial area and apical basis. The photoelastic analysis showed that the main factor in determining the force distribution is the apical basis and that the conical roots from cervical to apical (series III) elicit a lateral compression on the periodontal support, which influences the magnitude of the force that is necessary to the formation of the some photoelastic deformations produced in the other series. The spectral distribution of the internal stress in the patterns of the series III showed the formations of incomplete fringes along with the lateral aspects of the roots. It was concluded that to make a comparison of the periodontal distribution of occlusal forces, it is of paramount importance the standardization of all steps concerning the construction of the patterns, the measurement of the photoelastic blocks and mainly the apical area of the root, which is the main determinant factor of the qualitative and quantitative results produced by the photoelastic analysis.
