Abstract
OBJECTIVE To compare 2 different resin composites and 2 adhesive systems used in a new restorative protocol (partial restoration) to treat non-carious cervical lesions associated with gingival recession type 1 (RT1). MATERIAL AND METHODS Eighty combined defects (CDs) were treated with a partial restoration and periodontal plastic surgery for root coverage. The CDs were randomly assigned to one of the following groups: NP + TE (n = 20), nanofilled composite and 2-step total-etch adhesive system; NP + UA (n = 20), nanofilled composite and universal adhesive system; MH + TE (n = 20), microhybrid composite and 2-step total-etch adhesive; MH + UA (n = 20), microhybrid composite and universal adhesive. Restorations were assessed using the United States Public Health Service (USPHS) criteria at 1 week (baseline) and 6, 12, and 24 months. Survival rate, periodontal parameters, dentin hypersensitivity (DH), and aesthetics were also evaluated. RESULTS After 24 months, only the MH + TE group did not lose any restoration, with no significant differences between groups. For surface roughness parameter, MH presented 83.3% of the restorations scoring Bravo, whereas NP presented 48.5% of the restorations scoring Bravo. All groups presented restorations with marginal discoloration. All periodontal parameters behaved similarly, regardless of the restorative material. All groups presented significant reductions of dentin hypersensitivity and improved aesthetic perceptions (p < 0.05). CONCLUSION Both resin composites and adhesives tested can be combined for partial restorations to treat CDs. CLINICAL RELEVANCE This new restorative-surgical protocol to treat CDs presents satisfactory outcomes. The partial restorations can be successfully executed with both combinations of adhesives and resin composites evaluated in this investigation.

Abstract
BACKGROUND Evaluate the use of collagen matrix (CM) as adjunctive to coronally advanced flap (CAF versus CAF + CM) to treat gingival recession (GR) associated with non-carious cervical lesion-combined defects (CDs). METHODS Sixty-two patients presenting 62 CDs (RT1 GR and non-carious cervical lesion (NCCLs) were randomly allocated to either CAF group (n = 31): partial restoration of the NCCL and CAF; or to CAF + CM group (n = 31): partial restoration of the NCCL and CAF associated with CM. Clinical, esthetic, patient-centered outcomes, and restorative parameters were assessed. RESULTS After 12 months, CD coverage were 55.2% for CAF and 54.4% for CAF + CM (P = 0.8). Recession reduction were 1.9 ± 0.8 mm for CAF and 2.0 ± 0.7 mm for CAF + CM (P = 0.6). CAF+CM resulted in higher increase in keratinized tissue (KT) width (CAF: 0.3 ± 0.7 mm; CAF + CM: 0.9 ± 0.8 mm; P = 0.004) and KT thickness gain (CAF: 0.1 ± 0.3 mm; CAF + CM: 0.7 ± 0.2 mm; P = 0.001). Both treatments presented low postoperative pain and resulted in esthetics improvements. In addition, no restoration was lost, 27.4% showed a reduction of the superficial polishing, and 8% showed marginal staining, but still clinically acceptable. CONCLUSION Partial resin composite restoration (with the apical limit up to 1 mm of the estimated CEJ) and CAF alone or combined with CM are suitable for treating CDs. The use of CM provided additional benefits in terms of KT width and thickness gain. (NCT03341598).

Abstract
BACKGROUND The literature lacks long-term evidence regarding outcomes of the coronally advanced tunnel flap (TUN) combined with connective tissue graft (CTG) when compared to the trapezoidal coronally advanced flap (CAF) and CTG combination. This study presents 2-year results of a randomized clinical trial comparing CTG combined with either CAF or TUN in the treatment of single maxillary gingival recession (GR) defects. METHODS Thirty-nine patients, each contributing a single Miller Class I or II GR defect, were treated by CAF+CTG (control; n = 19) or TUN+CTG (test; n = 20) and completed the 2-year follow up. Clinical, patient centered, and esthetic evaluations were performed and differences among groups were analyzed. RESULTS At 2 years, mean root coverage for control and test group was 89.5% ± 14.6% and 87.7% ± 18.4%, respectively (P = 0.5). The corresponding complete root coverage prevalence was 68.4% and 50% (P = 0.4). Dentin hypersensitivity significantly decreased for both groups. The two groups showed improvement in esthetics, as assessed by both professionals and patients, without significant intergroup differences (P > 0.5). TUN+CTG sites were much more likely to present improvement in root coverage between 6 months and 2 years, exhibiting creeping attachment of 0.7 ± 0.6 mm. CONCLUSIONS At 2 years of follow up, both CAF+CTG and TUN+CTG resulted in significant clinical and esthetic improvements and provided similar results in the treatment of single maxillary GRs.

Abstract
This article aims to describe a modification of the semilunar coronally advanced flap. A total of 12 systemically and periodontally healthy patients presenting Miller Class I gingival recession were treated with the modified semilunar coronally advanced flap technique described in this article. After 1 year of follow-up, the mean root coverage was 85.4% ± 24.7%. Significant gingival recession reduction, clinical attachment gain, and reduction in dentin sensitivity was observed 1 year after surgery. This novel semilunar coronally advanced flap technique was demonstrated to be effective for root coverage in Miller Class I gingival recessions.

Abstract
Palatogingival groove (PGG) is a developmental anomaly affecting mainly the maxillary incisors. PGG incidence, depth, and length are clinically important because it may cause severe and localized periodontitis; and it may divide the root canal resulting in accessory foramina. This study aimedto analyze the presence, shape, length, and depth of the palatogingival groove in maxillary central incisors. 1,668 maxillary central incisors wereused. Each tooth had its root portion inspected in order to verify PGG presence and depth. The found palatogingival grooves were classified according to the system proposed by Gu [5], as follows: Type I (short and superficial), Type II (long and superficial), and Type III (long and deep). All teeth that showed the grooves were radiographed; five teeth had theirroot surface analyzed through Scanning Electron Microscopic (SEM); and four teeth corresponding to each PGG type were sent to obtain histologicalsections and then submitted to microscopic analysis. Of the 1.668 analyzed incisors, 27 (1.61%) showed the palatogingival groove: 8 (29.6%) Type I, 17 (63%) type II, and 2 (7.4%) Type III. Microscopic analysis revealed no communication between PGG and root canal. In conclusion, our results showed that PGG can be clinically and radiographically diagnosed on maxillary central incisors, with the type II being the most common. The professionalsshould be aware of the features of this groove due to its severe clinical consequences. KEYWORDSIncisor; Anatomical variation; Palatogingival groove

Abstract
UNLABELLED This study evaluates the effect of zoledronic acid (ZOL) on the osseointegration of titanium implants in rabbits with glucocorticoid (GC)-induced bone loss, and our findings demonstrated that a single dose of ZOL is able to reverse the detrimental effects of GCs on the osseointegration of titanium implants. INTRODUCTION The purpose of this study is to evaluate the effect of ZOL on the osseointegration of titanium implants in rabbits with GC-induced bone loss. METHODS Three groups of six NZW rabbits were treated for 18 weeks with saline (SALINE), GC (methylprednisolone, 0.35 mg/kg three times a week), or GC + ZOL (methylprednisolone + single dose of ZOL, 0.1 mg/kg). The animals received a titanium implant in the left tibia after 6 weeks and were killed at the 18th week. Bone mineral density (BMD) was measured with dual-energy X-ray absorptiometry at baseline, eighth week (W8), and 18th week (W18) after treatment to determine the change upon treatment (BMD). Histomorphometric and serum bone alkaline phosphatase analysis (BAP) were also performed. RESULTS At W8, GC group had a significant reduction in lumbar spine and tibia BMD compared with SALINE (p = 0.003 and p = 0.000), as also observed for GC + ZOL group (p = 0.014 and p = 0.003) just 2 weeks after ZOL treatment. In contrast, at W18, the GC + ZOL had an evident BMD rescue with similar lumbar spine and tibia BMD compared with SALINE (0.043 +/- 0.006 vs. 0.055 +/- 0.009 g/cm(2), p = 0.457 and 0.027 +/- 0.003 vs. 0.041 +/- 0.011 g/cm(2), p = 0.232) and a significantly higher BMD compared with the GC (p = 0.024 and p = 0.001). Histomorphometry revealed that osseointegration was significantly reduced in GC (tibia cortical thickness and diameter, bone-implant contact, total and peri-implant bone area) whereas GC + ZOL had these parameters similar to SALINE (p > 0.05). Likewise, ZOL reversed the BAP alteration induced by GC. CONCLUSIONS Our findings demonstrated that a single dose of ZOL is able to reverse the detrimental effects of glucocorticoids on the osseointegration of titanium implants, suggesting that ZOL therapy may improve the outcome of bone implants in patients with glucocorticoid-induced osteoporosis.

Abstract
Twelve chagasic patients between the ages of seven and twelve, in the indeterminate phase with serology and xenodiagnosis positive, received the specific treatment. Eight of these were evaluated after an eight-year treatment period and four were followed-up during 20 years. Two patients took 7 mg/kg of nifurtimox during sixty and ninety days and ten of these used 5-7 mg/kg of benznidazole during 60 days. The clinical outcome was verified through clinical examination, electrocardiogram and contrasted X-ray of the esophagus. After the treatment, only one patient presented negativity in all the examinations. Seven (58.4%) remained in the indeterminate form and despite the precocious treatment four chagasic patients (33.3%) progressed clinically to second degree cardiopathy and/or megaesophagus.

Abstract
A grave kala-azar infection in a 14 years old boy is described. The leishmanial infection failed to respond to ten interrupted courses of glucantime of variable duration (14-56 days) at a dose of 20mg Sb5/kg/day. However a favorable response occurred to intramuscular aminosidine sulphate (20mg/kg/day) for 20 days. This same regimen was repeated 20 days later. After the first treatment splenic puncture parasite density fell from 50 amastigotes per oil immersion field to 3 amastigotes in 10 fields. A further splenic puncture 7 months after treatment was negative. The marked hepatoesplenomegaly gradually resolved over 26 months follow up and he gained 13 kilograms in weight. After aminosidine sulphate therapy his Montenegro reaction become positive and his lymphocytes responded to leishmania antigens.

Abstract
An indirect fluorescent antibody test was performed on sera collected from dogs housed in the municipal kennel of Setúbal to assess the prevalence of antibodies to Ehrlichia canis, the causative agent of canine ehrlichiosis and to Rickettsia conorii, agent of boutonneuse fever in humans. Two other members of the family Rickettsiaceae, Coxiella burnetii and Rickettsia typhi, were included in the serosurvey. Of the 104 dogs tested, 85.6% had antibodies to R. conorii, 50% to E. canis, 26.9% to R. typhi, and 4.8% to C. burnetii. These high seroprevalence rates of dogs with antibodies all year around against Rickettsiaceae suggest that physicians, public health officers and veterinarians should more frequently consider the diagnosis of these infections in Portugal.
