The objective of this systematic review was to estimate the efficacy of protraction facemask on the correction of Class III malocclusion in the short term. A systematic review of articles was performed using different electronic databases (PubMed, Ovid, Cochrane Central Register of Controlled Trials, Web of Science, LILACS, and Google Scholar). Search terms comprised 'orthopedic treatment' and 'Class III malocclusion'. The selection criteria were set in order to include in this review only randomized clinical trials (RCTs) performed treating with facemask Class III growing patients. Studies' selection, data extraction, and risk of bias's assessment were executed independently by two authors using pre-defined data forms. All pooled analyses of data were based on random effects models. A pre-specified subgroup analysis was planned to evaluate the effect of preliminary rapid palatal expansion on facemask efficacy. Three RCTs met our inclusion criteria. In total, data from 155 patients (92 treated and 63 controls) were collected. The treated group showed the following significant changes: ANB° +3.66° [95%CI (2.58, 4.74)]; SNA° +2.10 [95%CI (1.14, 3.06)]; SNB° -1.54 [95%CI (-2.13, -0.95)]; SN-palatal plane -0.82° [95%CI (-1.62, -0.02)]; and SN-mandibular plane +1.51 [95%CI (0.61, 2.41)]. Heterogeneity varied from low to moderate (mean I(2) value: 41.4 ± 20.8). Facemask is effective correcting Class III malocclusion in the short term. The skeletal modifications induced by facemask are forward displacement of maxilla, backward displacement of mandible, clockwise rotation of the mandibular plane, and counterclockwise rotation of the maxillary plane.

BackgroundAsymmetric dimethylarginine (ADMA) plays a crucial role in endothelial function and maybe a link for the known interaction of periodontitis and coronary heart disease (CHD). In this pilot study, we compared the impact of gingival health, periodontitis (CP), CHD, or of both diseases (CP + CHD) on salivary and serum ADMA levels.MethodsThe clinical and periodontal characteristics, serum, and saliva samples were collected from 35 patients with CP, 33 patients with CHD, 35 patients with both CP + CHD, and 35 healthy subjects. Levels of ADMA and C‐reactive protein (CRP) were assessed with a commercially available kit.ResultsThe median (25% and 75% percentile) concentrations of salivary and serum ADMA were significantly higher in the CHD group [serum: 1.5 (1.2 to 1.8) μmol/L; salivary 1.3 (1 to 1.7) μmol/g protein, P < 0.01] and in the CP + CHD [serum: 1.8 (1.4 to 2.0) μmol/L; salivary 1.5 (1.2 to 1.7) μmol/g protein, P < 0.001] group compared to CP patients and controls. In univariate models, CP (P = 0.034), CHD (P < 0.001), and hs‐CRP (P < 0.001) were significantly associated with serum ADMA, whereas in a multivariate model, hs‐CRP remained a significant predictor of serum ADMA (P < 0.001). In a multivariate model, the significant predictors of salivary ADMA levels were hs‐CRP (P < 0.001) and education socioeconomic status (P = 0.042).ConclusionsPatients with CHD and CP + CHD presented higher levels of salivary and serum ADMA compared to healthy subjects and CP patients. hs‐CRP was a significant predictor of increased salivary and serum ADMA levels.

Odontoma is considered to be the most common odontogenic tumor of the oral cavity. Most odontomas are asymptomatic and are discovered during routine radiographic investigations and can cause disturbances in the eruption of the teeth, most commonly delayed eruption or deflection. By a retrospective study design, demographic and clinical data regarding patients who presented odontomas from year 1995 to 2015 were obtained in order and the influence of active therapy on the dentition and on the treatment of impacted teeth was analyzed. Forty-five patients (mean age 14.2 years) with 29 complex and 16 compound odontomas were included in this retrospective study. Initial symptoms were delayed eruption of permanent teeth (n = 25), pain (n = 6), swellings (n = 4), and no symptoms (n = 10); 31 patients were discovered by incidence, all of them via panoramic radiographs. The mandible/maxilla ratio was about 2:1 (31/15). Thirty-two out of 45 odontomas were in close proximity of at least 1 tooth (n = 21 at incisive). A total of 12 teeth were extracted (complex: n = 8; compound: n = 4). Of the nonextracted teeth, 33 teeth were displaced and retained. Of those, 29 teeth were aligned through orthodontic-surgical approach and 4 teeth erupted spontaneously after surgery during the follow-up period. An early detection of odontoma is more likely an accidental radiological finding, hence the need for routine radiographic analysis should be emphasized. Early diagnosis of odontomas in primary dentition is crucial in order to prevent later complications, such as impaction or failure of eruption of teeth.

Background and Objective Vitamin D has been considered to possess anti‐inflammatory and antimicrobial activity, which may be a link for the known interaction of periodontitis (CP) and coronary heart disease (CHD). This study investigated the association between serum vitamin D levels and periodontitis in patients with CP and with CHD. Furthermore, the objective was to determine whether periodontitis and CHD had an impact on serum vitamin D levels. Material and Methods Using a cross‐sectional design, a total of 46 patients with CP, 45 patients with CHD, 45 patients with both CP and CHD, and 43 healthy patients were enrolled in the present study. Results Patients in the CP (17.4 ± 5.2 ng/mL) and in the CP + CHD (16.5 ± 5.6 ng/mL) group presented a significantly lower mean serum level of 25(OH)vitamin D compared to patients in the CHD (24.6 ± 3.7 ng/mL) and healthy control groups (29.9 ± 5.4 ng/mL) (P < .001). 25(OH)vitamin D levels were positively correlated with the number of teeth and negatively with C‐reactive protein (CRP) and all periodontal parameters (P < .001). In all patients, there was a proportional increase of 25(OH)vitamin D levels with a progressive increase in number of teeth (P‐trend <.001) while there were a proportional decrease in 25(OH)vitamin D levels with a progressive increase in clinical attachment level (CAL, P‐trend = .001), probing depth (PD, P‐trend = .006), and bleeding sites (BOP, P‐trend <.001) levels. Conclusion Patients with CP and CP + CHD presented significantly lower serum levels of vitamin D compared to CHD and healthy controls. Moreover, the presence of CP negatively influenced serum vitamin D levels.

JIA patients with TMJ arthritis presented higher functional disability and lower OHRQoL scores compared with JIA patients without TMJ arthritis. TMJ arthritis was strongly associated with JIA duration and activity, especially in female patients.

Rapid maxillary expansion is not more effective than SME in expanding the maxilla in patients with posterior crossbite.
