Abstract
Objective to present a 12-month follow-up with photographic and tomographic analyses of the effect of polymethyl methacrylate-based bone cement graft (PMMA) in gingival exposure (GE) in patients with excessive gingival display (EGD). Methods Twelve patients with EGD were included. The PMMA was surgically placed. A frontal and lateral photograph protocol was performed at baseline (T0), 3 (T3), 6 (T6), and 12 months (T12) post-operatively. Soft tissue cone-beam computed tomography (ST-CBCT) was performed at T0 and T12. Measures included GE, length of the lip vermilion (LLV), lip shape (LS), nose width (NW), filter width (FW), nasolabial angle (NAS) while smiling, and nasolabial angle at rest (NAR). The height, thickness, and volume of the cement graft were also measured in the ST-CBCT. The comparisons were performed by Kruskal-Wallis test at 5 % of significance (p < 0.05). Results The height, thickness, and volume of the PMMA were respectively 12.84 ± 1.59 mm, 3.83 ± 0.53, and 1532.02 ± 532.52 mm3. PMMA significantly decreased GE from 8.33 ± 1.25 mm (T0) to 6.60 ± 0.93 mm (T12) (p < 0.01). NAR was 98.34 ± 9.28° at T0 and increased to 105.13 ± 7.33° at T12; however, the angle value was not statistically different (p = 0.08). LLV, LS, NW, FW, and NAS did not exhibit statistical differences between the baseline and follow-up periods. Conclusions PMMA significantly decreased GE in a 12-month follow-up without influencing adjacent soft tissue anatomical structures.

Abstract
OBJECTIVES To evaluate the stability of periodontal tissues 3 (T3), 6 (T6), and 12 (T12) months after esthetic crown lengthening (ACL) and the possible correlations between changes in those structures. MATERIALS AND METHODS Twenty individuals were evaluated through clinical assessment, photography, and tomography. Measurements included gingival margin (GM), clinical crown length (CCL), interdental papilla height (PH) and width (PW), gingival thickness (GT), bone thickness (BT), probing depth (PD), distance between alveolar crest and GM, distance between alveolar crest and cementoenamel junction. Nonparametric and correlation statistics were performed (p < 0.05). RESULTS CCL at T0 was 7.42 ± 0.70 mm and increased to 9.48 ± 0.49 mm immediately after ACL, but it decreased to 8.93 ± 0.65 mm at T12. PD decreased 0.60 mm from T0 to T6, and it increased 0.39 mm from T6 to T12. BT decreased 0.20 mm, while GT increased 0.29 mm from T0 to T12. Both PW and PH showed enlargement in T12. A positive moderate correlation was found between CCL/T0 and CCL/T12, GT/T0 and AC-GM/T12, BT/T0 and GT/T12. A few negative moderate correlations were PD/T0 and CCL/T12, PD/T0 and PH/T0, PD/T0 and BT/T12. CONCLUSIONS ACL procedure was effective. Although some rebound occurred, that was not clinically important. PD tended to reestablish its original length, partially due to a migration of GM during the healing period. Besides, a thickening of supracrestal soft tissues was observed. CLINICAL RELEVANCE The present study centers on the factors influencing the stability of periodontal tissues after esthetic crown lengthening, underscoring the procedure's influence on esthetics and biology and the need for careful treatment planning.

Abstract
OBJECTIVE(S) This scoping review aims to map the scientific literature on the therapies currently available for physical salivary stimulation in individuals with hyposalivation caused by radiotherapy. STUDY DESIGN Studies were included when they comprised the target population of adult individuals receiving radiotherapy of the head and neck region and who developed or were at risk of developing hyposalivation. Two reviewers selected the studies and extracted data on the type of physical salivary stimulation therapy used, the degree of glandular tissue involvement, and the percentage of salivary flow alteration. Therapies were classified according to either prophylactic application (before/during radiotherapy) or therapeutic application (post-radiotherapy). RESULTS Sixteen articles were included: 4 tested transcutaneous electrical nerve stimulation (TENS), 3 studied low-level lasers, 7 researched acupunctures, and 2 investigated acupuncture-like TENS. The outcomes of the prophylactic studies indicated beneficial effects (similar salivary flow or reduced salivary flow loss), although most studies did not include a comparable control group. Therapeutic studies presented conflicting results. CONCLUSION(S) Prophylactic therapies of physical salivary stimulation may produce better effects than therapeutic applications. However, the protocols best indicated could not be defined. Well-designed, controlled clinical trials should be researched in the future to support the clinical recommendation of any of these treatments.

Abstract
BACKGROUND Several systemic conditions can result in distinct degrees of salivary gland damage and consequent hypofunction. The development of successful management schemes is highly challenging due to the complexity of saliva. This study aimed to systematically map the literature on the physical stimulation of salivary glands for hyposalivation management and the response of individuals according to different systemic conditions causing salivary impairment. METHODS A systematic search in the literature was performed. Two reviewers independently selected clinical trials, randomized or not, that used physical stimulation to treat hyposalivation caused by systemic conditions. Studies evaluating healthy subjects without hyposalivation were included as controls. Single-arm clinical studies or case series were also included for protocol mapping (PRISMA extension for scoping reviews). RESULTS Out of 24 included studies, 10 evaluated healthy subjects, from which 9 tested transcutaneous electrical nerve stimulation (TENS) and 1 tested acupuncture and electroacupuncture. Fourteen studies evaluated individuals with hyposalivation: 6 applied TENS, 6 applied low-level laser therapy (LLLT), and 2 applied acupuncture, carried out in post-chemotherapy, medication use, postmenopausal women, hemodialysis patients, smokers, diabetics, Sjögren's syndrome (SS). All showed increased salivation after treatment, except for two LLLT studies in individuals with SS. CONCLUSIONS Among the different patient groups, individuals with Sjögren's syndrome (SS) exhibited the poorest responses, while those with medication-induced hyposalivation demonstrated the most favorable treatment outcomes, independently of the management strategy for saliva stimulation. It means that physical stimulation of salivary glands holds promise as an alternative for managing hyposalivation in cases of reversible gland damage. However, to make informed decisions in current practice, it is necessary to conduct new well-designed randomized clinical trials with appropriate methodologies.

Abstract
AIMS A previous meta-analysis showed that individuals with Type 2 diabetes mellitus (T2D) have a greater chance of developing both coronal caries and root caries than systemically healthy ones, which can be influenced by hyperglycemia per se. This study aimed to associate blood and salivary glucose levels with caries. METHODS This research is a subset of a cross-sectional study. N = 39 individuals underwent a dental examination and salivary glucose, fasting blood glucose (FBG) and glycated hemoglobin (A1c) measurements. RESULTS The prevalence of active coronal caries was 10.2%, and that of root caries was 20.5%. A1c and FBG averages were higher in individuals with root caries (9.75 ± 1.71 and 186.3 ± 62.5) than without (7.01 ± 2.23 and 115.1 ± 48.6; p < 0.05). Individuals with T2D showed weak correlation of salivary glucose and number of active coronal caries. Significant correlations were observed between salivary and blood glucose. There was relevance of A1c (0.53; CI=0.124-0.941; p = 0.01) and FBG (0.019; CI=0.006-0.033; p = 0.006) toward the increased number of root caries lesions, even after adjustment for salivary flow and age. CONCLUSION Blood glucose levels are associated with an increased number of root caries in adults with or without T2D. In individuals with T2D, salivary glucose was correlated with active coronal caries. Additional studies are needed to support this association.

Abstract
The high concentration of glucose in the blood in Type 2 diabetes (T2D) may be related to either insulin resistance or insulin deficiency. Moreover, the literature points to periodontitis as the main oral disease caused by glycemia imbalance. The quantification of inflammatory markers in blood or saliva samples of T2D patients may represent a valuable tool in revealing how well an individual's immune system can respond to injuries and periodontal treatment. In addition, an evaluation of the cytokine expression is extremely relevant to help understand the connection between periodontitis and T2D. This systematic review and meta-analysis aimed to evaluate the expression of inflammatory markers in T2D patients with periodontitis, compared with non-diabetic patients with periodontitis. A total of 3,894 studies were retrieved after a systematic literature search, 15 of which were included in the systematic review, and 4 of these 15, in the meta-analysis. The results did not indicate any statistical difference between the groups regarding TNF-α and IL-6 markers. T2D patients with periodontitis had increased levels of IL-10, compared with non-diabetic individuals with periodontitis (p = 0.003). On the other hand, the IL-4 concentration in non-diabetic individuals with periodontitis was high, compared with the T2D group (p< 0.001). Several studies did not include quantitative results and were excluded from the meta-analysis. The high IL-10 expression and low IL-4 expression in the T2D group suggest an association between the level of these markers and the impairment of the immune response in T2D patients with periodontitis.

Abstract
There is emerging evidence that several oral diseases and conditions can be associated with DM. Dental caries, hyposalivation, fungal diseases and endodontics lesions may represent potential oral complications that can be aggravated by chronic hyperglycemia. Individuals with DM have a low perception of oral diseases which can lead to clinically important oral and systemic complications. This review aims to provide data on the most common oral signs and symptoms related to DM and to explore the mechanisms that might explain associations between DM and oral diseases in order to clarify the risks posed by poor oral health in DM. Since the linkage between oral diseases and DM is part of multifactorial aspects related to chronic hyperglycemic status and several common conditions affecting the whole body, both require rigorous self-control from patients and attention from medical and dental professionals.

Abstract
Objective To investigate the effects of nonsurgical periodontal therapy on levels of
high-sensitivity C-reactive protein in the sera and its association with body mass
index and high density lipoprotein in subjects with severe periodontitis. Methods Sera from 28 subjects (mean age: 34.36±6.24; 32% men) with severe periodontitis
and 27 healthy controls (mean age: 33.18±6.42; 33% men) were collected prior to
periodontal therapy. Blood samples were obtained from 23 subjects who completed
therapy (9-12 months). Oral and systemic parameters such as the number of blood
cells, glucose examination, lipid profile, and high-sensitivity C-reactive protein
levels accessed by high-sensitivity immunonephelometry assay, were included. Results Before therapy, in the periodontitis group, the ratio of subjects with
high-sensitivity C-reactive protein <0.3 mg/dL was statistically lower than in
the control group (P<0.0216). After therapy, the ratio of
subjects with high-sensitivity C-reactive protein <0.3 mg/dL was significantly
higher (65.22%) (P<0.0339). The mean value for body mass index
was statistically lower in subjects with high-sensitivity C-reactive protein
<0.3 mg/dL (24.63±4.19), compared with those with high-sensitivity C-reactive
protein >0.3 mg/dL (28.91±6.03) (P<0.0411). High density
lipoprotein presented a mean value statistically higher after therapy
(P<0.0027). Conclusion In systemically healthy subjects with periodontitis, periodontal therapy was
associated with decreased levels of circulating high-sensitivity C-reactive
protein and increase of high density lipoprotein in serum. The clinical trial was
registered at http://www.clinicaltrials.gov.br/, No. RBR-24T799.

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
PURPOSE To compare phagocytic activity of peripheral blood neutrophils from subjects with and without periodontal disease and evaluate the effects of periodontal therapy in individuals with similar levels of resolution of inflammation at the end of treatment. MATERIALS AND METHODS To compare the phagocytic activity of neutrophils, peripheral blood was collected from 27 control subjects with a healthy periodontium and 28 periodontitis subjects before and after treatment. The phagocytosis of killed Saccharomyces cerevisiae, pre-sensitised or non-sensitised with fresh serum from the donor, was quantified and a phagocytic index was calculated as the mean number of yeast cells phagocytised by the percentage of neutrophils involved in phagocytosis. RESULTS Prior to periodontal treatment, subjects with periodontitis exhibited significantly lower neutrophil phagocytic activity than control subjects with a healthy periodontium. Periodontal treatment significantly improved in clinical periodontal status and resulted in significantly increased phagocytosis of both pre-sensitised (from 113.0 pre- to 157.0 post-treatment, P = 0.02) and non-sensitised S. cerevisiae (from 1.5 pre- to 3.5 post-treatment, P = 0.001), to levels observed in control subjects. CONCLUSIONS The phagocytic activity of peripheral blood neutrophils from subjects with periodontal disease was lower than that of healthy controls. Subjects who underwent non-surgical periodontal treatment and strict supportive therapy for 6 months showed improved phagocytic activity in peripheral blood neutrophils. The phagocytic index values from subjects with periodontal disease after treatment achieved those found in the control group.

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
Objectives The purpose of this study was to evaluate the prevalence of alveolar bone loss
(BL) in healthy children treated at private pediatric dentistry clinics in
Brasília, Brazil. Material and Methods The research included 7,436 sites present in 885 radiographs from 450 children.
The BL prevalence was estimated by measuring the distance from the cementoenamel
junction (CEJ) to alveolar bone crest (ABC). Data were divided in groups: (I) No
BL: distance from CEJ to ABC is ≤2 mm; (II) questionable BL (QBL): distance
from CEJ to ABC is >2 and <3 mm; (III) definite BL (DBL): distance from CEJ
to ABC ≥3 mm. Data were treated by the chi-square nonparametric test and
Fisher's exact test (p<0.05). Results Among males, 89.31% were classified in group I, 9.82% were classified in group II
and 0.85% in group III. Among females, 93.05%, 6.48% and 0.46% patients were
classified in Group I, II and III, respectively. The differences between genders
were not statistically significant (Chi-square test, p = 0.375). Group composition
according to patients’ age showed that 91.11% of individuals were classified as
group I, 8.22% in group II and 0.67% in group III. The differences among the age
ranges were not statistically significant (Chi-square test, p = 0.418). The mesial
and distal sites showed a higher prevalence of BL in the jaw, QBL (89.80%) and DBL
(79.40%), and no significant difference was observed in the distribution of QBL
(Fisher’s exact test p = 0.311) and DBL (Fisher’s exact test p = 0.672) in the
dental arches. The distal sites exhibited higher prevalence of both QBL (77.56%)
and DBL (58.82%). Conclusions The periodontal status of children should never be underestimated because BL
occurs even in healthy populations, although in a lower frequency.

Abstract
Objectives The aim of this study was to analyze the periodontal parameters of patients with
chronic renal failure. Material and Methods The periodontal status of 16 Brazilian patients aged 29 to 53 (41.7±7.2)
years with chronic renal failure (CRF) and another matched group of 14 healthy
controls with periodontitis was assessed clinically and microbiologically. Probing
pocket depth (PPD), gingival recession (GR), dental plaque index (PLI), gingival
index (GI), and dental calculus index (CI) were the clinical parameters recorded
for the entire dentition (at least 19 teeth), while the anaerobic
periodontopathogen colonization in four sites with the highest PPD was evaluated
using the BANA test (“PerioScan”; Oral B). Results The results for the CRF group and control group, respectively were: PPD:
1.77±0.32 and 2.65±0.53; GR: 0.58±0.56 and 0.51±0.36;
PLI: 1.64±0.56 and 1.24±0.67; GI: 0.64±0.42 and
0.93±0.50; CI: 1.17±0.54 and 0.87±0.52. Comparison between
groups using the "t" test revealed a significantly increased PPD (p<0.001) in
the control group. Comparison of the other clincial parameters by the Mann-Whitney
test showed differences only for PLI, which was significantly higher (p<0.05)
in the CRF group. Spearman's test applied to each group showed a positive
correlation among all clinical parameters, except for GR (p<0.05). None of the
groups showed any correlation between GR and GI, while a significant negative
correlation between GR and PPD was observed for the CRF group. The percentage of
BANA-positive sites was 35.9% for the CRF group and 35.7% for the control group.
The BANA test correlated positively with PPD only in the control group and with GR
only in the CRF group. Conclusions In spite of a higher PLI and dense anaerobic microbial population even in shallow
PPD, patients with CRF exhibited better periodontal conditions than periodontitis
patients, which is an evidence of altered response to local irritants.

Abstract
Os trabalhos realizados no Brasil a respeito das principais afecções bucais dos gerontes mostram situação preocupante. O objetivo deste estudo foi estimar a frequência de edentulismo, analisar o uso e a necessidade de prótese, calcular o índice CPOD e verificar a condição periodontal de idosas residentes no Distrito Federal. Cento e quarenta mulheres com idade igual ou superior a sessenta anos foram examinadas. A condição de cada prótese foi avaliada observando presença de prejuízo estético ou funcional. Em seguida, foi realizado exame clínico para detectar a presença de cárie, restaurações e dentes perdidos para cálculo do índice CPOD. O exame periodontal incluiu a verificação do índice de placa visível, índice de sangramento gengival, medidas de profundidade de sondagem clínica, perda de inserção clínica e mobilidade dental de todos os dentes presentes. Os resultados revelaram péssimas condições bucais dos pacientes examinados. A taxa de edentulismo mostrou-se elevada, o índice CPOD foi alto (29,8), com predomínio do componente extraído (87,1%) e a condição periodontal foi considerada grave. A partir destes dados, pode-se concluir que o perfil da condição bucal das idosas representadas neste estudo é precário, o que reflete a necessidade de se elaborar programas de promoção de saúde e de reabilitação para este segmento da população.

Abstract
AIM The aim of the present paper is to report a case of benign cementoblastoma (BC) involving multiple maxillary teeth and discuss the importance of its diagnosis in clinical oral practice. BACKGROUND BC is a rare, benign odontogenic neoplasm of ectomesenchymal origin. This neoplasm has characteristic radiologic and microscopic features, and it is intimately associated with the roots of teeth. CASE REPORT The intra-oral examination in a 21-year-old white man revealed a palatine growth in the premolar-molar region. Dental panoramic and periapical radiographies showed a mixed radiodense/radiolucent lesion closely associated with the roots of three maxillary teeth. A biopsy was undertaken and confirmed the clinical hypothesis. SUMMARY In most cases, initial BC is asymptomatic and early diagnosis can be performed by routine radiographic examination. BC was considered as an indolent lesion for several years. Nevertheless, recent studies have demonstrated that some BCs may exhibit aggressive biological behavior and can affect several teeth. CLINICAL SIGNIFICANCE Because a benign cementoblastoma represents an odontogenic lesion, general practicing professionals must be able to identify the main features of this tumor. This case corroborates some papers that have demonstrated a possible aggressive behavior of BC. Therefore, a brief update concerning the clinical and radiographic features of this unique tumor is also provided.
