RESUMEN
BACKGROUND: The objective of this study was to evaluate the risk of maxillary canine impaction through cephalometric evaluation. METHODS: One hundred and eighty-two Caucasian patients (80 males and 102 females) with a mean age of 12.4±0.5 were retrospectively enrolled in the present study. Ninety patients with impacted canines were compared with ninety-two patients with physiologically erupted canines. The following cephalometric variables were analyzed: SNA, ANB, SN-GOME, GO-ME, SP-CL, SELLA TURCICA DEPHT, A-Pt LINE, B-Pt LINE, A-Pt LINE°, B-Pt LINE°, A1s-Pt, A1i-Pt, A1s-Pt°, A1i-PT°, A-SN, B-SN and SN-U1. When applicable, a paired sample t-test was performed to investigate the difference in means between the two sample groups, while the Mann-Whitney Test was used as a non-parametric test in the case of a non-normal distribution of data. Statistical significance was set at P<0.05. RESULTS: The group with impacted canines showed an increase in Go-Me distance, SNA angle and A1s-Pt angle compared with the control group. In addition, the same group showed a decrease in A-SN and SP-Cl distance compared with the control group. CONCLUSIONS: An increase in mandibular length (GO-ME) and SNA angle associated with a reduction in A-Sn distance and interclinoid distance (SP-Cl) were observed in patients with impacted canines.

OBJECTIVE: Lower tooth crowding is considered one of the most common malocclusions in growing patients and due to the potential complications associated with it, it is recommended to intercept this condition as soon as possible. The purpose of this paper is to examine and compare the effectiveness of two different orthodontic devices (elastodontic device and clear aligners) in the treatment of anterior tooth crowding in the jaws of young patients. MATERIALS AND METHODS: Seventy patients aged between 10 and 16 years with anterior inferior tooth crowding were recruited into this study and divided into case and control groups. The former group comprised 35 patients (15 males and 20 females, average age 10.2 years) who were treated with elastodontic devices (EQ CP series, Eptamed), while the control group consisted of 35 patients (15 males and 20 females, average age 10.5 years) who received aligners (Invisalign). All patients underwent periodic visits after 6 months from the start of treatment (T1) and after 1 year (T2) in which the progress of therapy was evaluated by measuring the inferior intercanine distance using a digital caliper. A parametric ANOVA test was conducted for statistical analysis. RESULTS: There is no statistically significant difference between the two groups at either T1 or T2 (p < 0.05), thus making the two treatment modalities comparable. CONCLUSIONS: Both elastodontic devices and aligners can be considered as effective tools to successfully conduct inferior expansive treatment for the resolution of tooth crowding; however, the elastodontic devices are considered more comfortable to wear and they are required to be worn for less time during the day.
RESUMEN
BACKGROUND: Enamel plays an essential role in protecting the underlying layers of the human tooth; therefore, preserving it is vital. This experimental study aimed to evaluate the potential ability of L. brevis to counteract the action of a demineralizing agent on dental enamel morphology and mineral composition in vitro. METHODS: The sample consisted of 12 healthy human posterior teeth. The coronal portion of each tooth was subdivided into two equal parts longitudinally. The specimens were randomly divided into four groups: artificial saliva, L. brevis suspension, demineralizing agent (DA), and DA plus L. brevis. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) were used to evaluate the surface micromorphology and the mineral content, respectively. The statistical analysis was conducted using a one-way ANOVA, followed by Tukey's post hoc test. RESULTS: SEM analysis did not highlight significant changes in the enamel microstructure of L. brevis-treated specimens compared to the control. DA-induced damage to the enamel structure was drastically reduced when the specimens were contextually exposed to the probiotic. The treatment with DA substantially reduced the weight % of crucial enamel minerals, i.e., Ca and P. Notably, the probiotic was able to reverse the demineralization process, bringing Ca and P weight % back to basal levels, including the Ca/P ratio. CONCLUSIONS: The findings indicate that L. brevis is able to efficiently protect the dental enamel surface from the damage caused by DA and increase the enamel resistance to demineralization. Overall, L. brevis confirms its efficacy in preventing or counteracting the action of carious lesions through a novel mechanism that protects the tooth surface under a chemical challenge that mimics the caries process.

This is a review of the literature on the main neuromodulation techniques, focusing on the possibility of introducing sensory threshold ULFTENS into them. Electro neuromodulation techniques have been in use for many years as promising methods of therapy for cognitive and emotional disorders. One of the most widely used forms of stimulation for orofacial pain is transcutaneous trigeminal stimulation on three levels: supraorbital area, dorsal surface of the tongue, and anterior skin area of the tragus. The purpose of this review is to trigger interest on using dental ULFTENS as an additional trigeminal neurostimulation and neuromodulation technique in the context of TMD. In particular, we point out the possibility of using ULFTENS at a lower activation level than that required to trigger a muscle contraction that is capable of triggering effects at the level of the autonomic nervous system, with extreme ease of execution and few side effects.
RESUMEN
BACKGROUND: Metabolic syndrome (MetS) is a cluster of atherosclerotic risk factors that increases cardiovascular risk. MetS has been associated with periodontitis, but the contribution of single MetS components and any possible sexual dimorphism in this relation remain undetermined. METHODS: Using the third National Health and Nutrition Examination Survey (NHANES III), we performed a nested cross-sectional study to test whether individuals aged > 30 years undergoing periodontal evaluation (population) exposed to ≥ 1 MetS component (exposure) were at increased risk of bleeding/non-bleeding periodontal diseases (outcome) compared to nonexposed individuals, propensity score matched for sex, age, race/ethnicity, and income (controls). The association between MetS components combinations and periodontal diseases was explored overall and across subgroups by sex and smoking. Periodontal health status prediction based on MetS components was assessed. RESULTS: In total, 2258 individuals (n. 1129/group) with nested clinical-demographic features were analyzed. Exposure was associated with gingival bleeding (+ 18% risk for every unitary increase in MetS components, and triple risk when all five were combined), but not with stable periodontitis; the association was specific for women, but not for men, irrespective of smoking. The only MetS feature with significant association in men was high BP with periodontitis. CRP levels significantly increased from health to disease only among exposed women. MetS components did not substantially improve the prediction of bleeding/non-bleeding periodontal disease. CONCLUSION: The observed women-specific association of gingival bleeding with single and combined MetS components advances gender and precision periodontology. Further research is needed to validate and expand these findings.

BACKGROUND: Reduced access to dental care may increase cardiovascular risk; however, socioeconomic factors are believed to confound the associations. We hypothesized that the relation persists despite economic wellness and high education, with reduced access to dental care affecting cardiovascular risk at least in part through its effect on blood pressure (BP), possibly mediated by systemic inflammation. METHODS: We first assessed the sociodemographic and clinical characteristics related to last dental visit timing (≤ or >6 months; self-reported) using national representative cross-sectional data. Then, the association of last dental visit timing with clinic BP was selectively investigated in highly educated, high income participants, further matched for residual demographic and clinical confounders using propensity score matching (PSM). The mediating effect of systemic inflammation was formally tested. Machine learning was implemented to investigate the added value of dental visits in predicting high BP over the variables included in the Framingham Hypertension Risk Score among individuals without an established diagnosis of hypertension. RESULTS: Of 27,725 participants included in the population analysis, 46% attended a dental visit ≤6 months. In the PSM cohort (n = 2350), last dental visit attendance >6 months was consistently associated with 2 mmHg higher systolic BP (P = 0.001) and with 23 to 35% higher odds of high/uncontrolled BP compared with attendance ≤6 months. Inflammation mildly mediated the association. Access to dental care improved the prediction of high BP by 2%. CONCLUSIONS: Dental care use impacts on BP profiles independent of socioeconomic confounders, possibly through systemic inflammation. Regular dental visits may contribute to preventive medicine.

BACKGROUND: This study aimed to verify the efficacy of two elastodontic devices in overjet (OJ) and overbite (OB) reduction during treatment with the Equilibrator Series II (Eptamed) and Occlus-o-Guide (Sweden & Martina) devices. METHOD: Sixty patients aged 7-15 years were enrolled in the study, and were divided into test and control groups. The test group included 30 patients (14 males, 16 females; mean age, 10.66 ± 2.12 years) treated with the EQ (Equilibrator) Series II. The control group included 30 patients (15 males, 15 females; mean age, 10.76 ± 2.52 years) treated with the Occlus-o-Guide. The two groups exhibited the same orthodontic features. The orthodontic criteria were: skeletal and dental class II malocclusion (divisions 1 and 2); and the presence of OJ and OB. Evaluation of OJ and OB was performed at two timepoints: T0 (before starting therapy) and T1 (after 1 year). RESULTS: At T0, OJ and OB were similar for the two groups; however, at T1, both OJ and OB were significantly lower with the Eptamed device compared to the Occlus-o-Guide device (p = 0.0019). CONCLUSIONS: Elastodontic devices improve orthodontic outcomes by aiding orthodontic patient management, diagnosis, and treatment planning, reducing the risk relapse acting on the whole organism and the rehabilitation of the tongue.

BACKGROUND: Cardiovascular diseases (CVD) including hypertension, are characterized by underlying systemic inflammation. Periodontitis, which can impact the systemic inflammatory burden has recently been linked to high blood pressure (BP). However, the relationship of gingival bleeding, as an easily accessible marker of periodontal disorder, with hypertension, remains unclear. METHODS: Survey-based propensity score matching (PSM) incorporating major confounders shared between hypertension and periodontal diseases was applied to cross-sectional NHANES III data from 5396 adults at least 30 years old who underwent BP measurement and periodontal examination, identifying two matched groups with and without gingival bleeding. The association of bleeding gums with SBP (mmHg) and high/uncontrolled BP was then assessed with generalized additive models incorporating inflammatory markers. Stratification by periodontal status (healthy; gingivitis; stable periodontitis; unstable periodontitis) was performed. Variables importance was estimated using machine learning. RESULTS: Gingival bleeding (gingivitis; unstable periodontitis) was independently associated with +2.6âmmHg (Pâ<â0.001) SBP compared with no bleeding (healthy periodontium; stable periodontitis), and with greater odds (ORâ=â1.42; 95% CIâ=â1.19-1.68; Pâ<â0.001) of high/uncontrolled BP. Participants with unstable periodontitis had higher SBP than those with stable periodontitis (+2.1âmmHg; Pâ<â0.001) or gingivitis (+5.3âmmHg; Pâ<â0.001). Unstable periodontitis and gingivitis were consistently associated with increased risk of high/uncontrolled BP (ORâ=â1.65, 95% CIâ=â2.14-1.82; ORâ=â1.49, 95% CIâ=â1.22-1.82, respectively). Inflammatory markers allowed a maximum of 12% gain in the models' predictive power. CONCLUSION: Gingival bleeding contributes to shaping the relationship between periodontal diseases and BP, but the burden represented by periodontitis is also crucial. Periodontal evaluation might be of importance in difficult to control hypertension.

Recent studies showed an evident correlation between the stomatognathic system and the visual system. These results suggest that subjects who are affected by both temporomandibular (TMD) disorders and refractive disorders present with altered control of pericranial musculature tone and higher open-eye electromyographic (EMG) values. The objective of this work was to evaluate the effects of standard vision correction on EMG in subjects suffering from TMD compared with application of the same vision treatments to non-TMD subjects. 40 subjects were enrolled in this study. The test group included 20 myopic subjects and also included patients with TMD. The control group included 20 healthy myopic subjects. All of the participants underwent a complete ocular examination and a sEMG analysis. The results showed that TMD subjects with vision disorders that are corrected with standard glasses present EMG values that are significantly higher than those presented by non-TMD subjects with vision disorders and standard glasses. Infact, in TMD subjects, eye correction did not have a positive effect on the stomatognathic or pericranial musculature.

RESUMEN
Obstructive sleep apnea syndrome (OSAS) is one of the most challenging diseases to treat in medicine. Here, the authors describe a case of OSAS treated with a lingual elevator of Balercia (ELIBA®). The patient, a forty-five-year-old Caucasian male, had a chief complaint of numerous episodes of nocturnal apnea. After several visits with specialists, a polysomnographic examination was performed, in which the patient's apnea hypopnea index (AHI) was 30.4, and a lingual elevator was prescribed. The lingual elevator helped to keep the patient's tongue in the correct position and prevented the tongue from reverting back to the soft tissue spaces in the mouth. After six months of treatment with the lingual elevator and dietary adjustments, the patient's AHI decreased to 11.6. This simple yet customizable approach is a comfortable and easy option for patients to reduce night apnea episodes.
RESUMEN
AIM: Periodontitis is a relapsing-remitting disease. Compared with bleeding on probing (BoP), expression of disease activity, periodontal inflamed surface area (PISA), incorporates chronic disease parameters. We tested the association of PISA and BoP with blood pressure (BP) in NHANES III. MATERIALS AND METHODS: A total of 8,614 subjects (≥30 years) with complete periodontal and BP examinations were enrolled. PISA was derived from periodontal probing depth and BoP. The association of PISA and BoP with high/uncontrolled BP was examined by multiple-adjusted models. Inflammatory markers were tested as possible mediators. A machine learning (ML) approach was used to define the relative importance of PISA and BoP and estimate the power of BP status prediction. RESULTS: Compared to no inflammation, severe PISA and BoP were associated with 43% (p < .001) and 32% (p = .006) higher odds of high/uncontrolled BP (≥130/80 mmHg), and with higher systolic BP by ≈4 (p < .001) and 5 (p < .001) mmHg, respectively. Inflammatory markers appeared to mediate this association with various extents, without threshold effect. BoP predicted high/uncontrolled BP more efficiently than PISA using ML. CONCLUSION: PISA and BoP describe the association of periodontal inflammation and hypertension with subtle differences. The contribution of local inflammation to the global inflammatory burden might explain the observed findings.

Background: Tenderness of masseters and temporalis can be considered a relevant tool for diagnosis of myo-type craniofacial pain disorders, but a limit of pain score systems is that they are based on subjective pain perception. Surface electromyography (sEMG) is a noninvasive and reliable tool for recording muscle activity. Therefore, we investigated whether a correlation exists between tenderness on masseters and temporalis, assessed by subjective pain scale, and muscles activity, evaluated by sEMG, in patients with painful temporomandibular disorder (TMD) and concurrent tension-type headache (TTH). Methods: A cross-sectional study on fifty adult volunteer patients with TMD and TTH, who underwent tenderness protocol according to Diagnostic Criteria for TMD (DC/TMD) guidelines, was conducted followed by sEMG recording of temporalis and masseters. Pearson's correlation was performed to investigate the correlation between muscular activity and subjective pain scores. Results: An overall moderate correlation between muscle tenderness and sEMG values (y = 1 + 1.2 · x; r 2 = 0.62; p < 0.0001), particularly in the temporalis, was observed. Segregation of data occurred according to tenderness and sEMG values. At the highest pain score, the mean sEMG absolute value was higher at the temporalis than the masseters. Conclusions: Our study provides evidence that subjective pain perception can be objectively quantified at a magnitude proportional to pain severity. At greater tenderness scores, higher sEMG activity at the level of temporalis could help discriminate clinically prevalent TTH versus prevalent TMD. sEMG confirms to be an accurate tool to reliably objectify the subjective perception of pain. When combined with clinical evaluation and patients' symptoms, sEMG increases diagnostic sensitivity in the field of myo-type craniofacial pain disorders. This trial is registered with NCT02789085.

Background: Temporomandibular joint dysfunction (TMD) therapy remains an open challenge for modern dentistry. Herein, we propose a new neuromuscular lingual device able to reduce signs and symptoms of TMD in female patients with chronic orofacial pain. Methods: 50 females with myofascial TMD according to RDC/TMD were randomly assigned to study (n = 25) and control groups (n = 25). At T0, both groups received sEMG/KNG and pain evaluation by the VAS scale. The study group received the ELIBA device (lingual elevator by Balercia) constructed under ULF-TENS (ultra-low-frequency transcoutaneous electrical nervous stimulation). Subjects were instructed to use ELIBA at least for 16 h/day. After 6 months (T1), both groups underwent to sEMG/KNG and VAS revaluation. Results: T1 study group compared to controls showed a significant reduction in total (p < 0.0001) and mean (p < 0.0001) sEMG values, as well as a significant increase in both maximum vertical mouth opening (p=0.003) and maximum velocity in mouth opening (p=0.003) and closing (p < 0.0001). Interestingly, a significant reduction in pain measured by VAS (p < 0.0001) was reported. Conclusions: After 6 months, the ELIBA device is able to significantly reduce TMD-associated myogenous pain and to promote the enhancement of sEMG/KNG values. Practical Implications: ELIBA can be considered as a new device, potentially useful for head-neck pain relief in patients suffering from chronic TMD. In addition, its use promotes a muscles relaxation inducing freeway space increase. This characteristic makes it particularly useful for rehabilitation of patients with not enough space for construction of conventional orthotics or neuromuscular bites.

BACKGROUND: Increasing evidence links periodontal microbiota to several systemic conditions, including high blood pressure (BP). Antibodies to oral pathogens can be considered an indirect assessment of periodontal bacterial burden. We aimed at assessing the relationship between systemic exposure to periodontal microbiota, expressed in terms of relative antibodies, and BP, using data from the third National Health and Nutrition Examination Survey (NHANES III). METHODS: We analyzed cross-sectional, nationally representative data from 7,928 adults aged ≥40 years who underwent determination of BP and serum antibodies to 21 periodontal microorganisms. BP was examined as both continuous (mmHg) and binary (â·130/80 mmHg, i.e. normal/controlled or high/uncontrolled BP) variables. Pearson and Spearman correlations restricted maximum likelihood, crude and adjusted generalized additive models, and a machine learning approach based on gradient boosting modeling were combined to verify any association between antibodies to periodontal microbiota and BP. RESULTS: Antibodies to Campylobacter rectus, Veillonella parvula, Prevotella melaninogenica were consistently associated with high/uncontrolled BP by about +3 mmHg of systolic and +2 mmHg of diastolic BP and with 10% to 13% higher odds of high/uncontrolled BP, as well as with more active periodontal disease and greater changes in clinical parameters of periodontitis. Antibodies to C. rectus resulted in the strongest association with BP. CONCLUSIONS: There is an association between systemic exposure to periodontal microbiota and BP. Understanding the pathogenetic mechanisms that shape such relationships, and the relative potential impact on personalized medicine, is the challenge of future research.

OBJECTIVE: To compare the clinical efficacy of two techniques for fabricating a Bimler device by assessing the patient's surface electromyography (sEMG) activity at rest before treatment and six months after treatment. METHODS: Twenty-four patients undergoing orthodontic treatment were enrolled in the study; 12 formed the test group and wore a Bimler device fabricated with a Myoprint impression using neuromuscular orthodontic technique and 12 formed the control group and were treated by traditional orthodontic technique with a wax bite in protrusion. The "rest" sEMG of each patient was recorded prior to treatment and six months after treatment. RESULTS: The neuromuscular-designed Bimler device was more comfortable and provided better treatment results than the traditional Bimler device. CONCLUSION: This study suggests that the patient group subjected to neuromuscular orthodontic treatment had a treatment outcome with more relaxed masticatory muscles and better function versus the traditional orthodontic treatment.

Background: Neutral zone (NZ) is a specific area in the oral cavity where muscular opposite forces are null. NZ represents the ideal zone for prosthesis placement. In this study, we compared digital implant planning using conventional technique and using NZ registration through piezography. Methods: Sixty-tree implants were digitally planned. Angular deviation differences between traditional planned and NZ-planned implants were calculated. In addition, interferences with soft tissues (i.e., tongue and cheeks) were evaluated. Results: We observed a significant difference between traditional technique and piezographic approach in terms of implants angulation (p = .003), independent of site. A 4.7% of the planned abutments with traditional technique were placed outside the NZ, causing conflict with soft tissues in the digital model. Conclusions: Compared with traditional technique, piezography allows a significantly different exploitation of the nonconflict area, which potentially translates into better management of soft tissues and improved functionality of the implants.

Periodontal disease is a chronic inflammatory disorder of the tissues surrounding the teeth, with evidence of systemic effects. Some studies showed the benefit of periodontal therapy on blood pressure (BP), but the impact of periodontitis on BP control is unknown. We retrospectively analyzed cross-sectional, nationally representative data from treated hypertensive adults aged ≥30 years with and without periodontitis. BP was examined as both continuous (mm Hg) and categorical (treatment goal achievement status according to guidelines: at goal and above goal) variable according to the presence or absence of periodontitis and its clinical parameters (probing depth, clinical attachment loss, and disease severity [mild, moderate, and severe]). Systolic BP means and odds ratios for uncontrolled BP according to the presence and severity of periodontitis were calculated using progressively adjusted models. Among treated hypertensive adults, mean systolic BP was about 2.3 to 3 mm Hg higher in the presence of periodontitis ( P<0.0001). Periodontitis was associated with unsuccessful antihypertensive treatment after multiple adjustments, with higher odds by disease severity. A good periodontal health is associated with better systolic BP profile during antihypertensive therapy by about 2.3 to 3 mm Hg and with lower odds of antihypertensive treatment failure. Dedicated studies are needed to test the impact of periodontal therapy on BP and the long-term effects on cardiovascular outcomes of this complementary approach to systemic health.

PURPOSE: To investigate the short- and long-term effects of different combinations of dietary instructions on cariogenic food intake and salivary cariogenic bacteria (Streptococcus mutans [SM] and Lactobacillus [LB]). MATERIALS AND METHODS: In this randomised 2-arm parallel study, 75 6-year-old subjects were assigned to repeated (group A; 19M/19F) or isolated (group B; 17M/20F) verbal and/or written dietary advice (VWDA), with foods classified by cariogenic potential. Both groups underwent a baseline salivary test for SM/LB, kept a monthly food diary, and attended 4 weekly visits (T1-T4). At T1-T2; group A only received VDA. At T3, both groups received VWDA. At T4, participants handed in their food diaries and underwent another salivary test. After 1 year (T5), subjects were recalled for weekly food diary monitoring and salivary testing. Relative risk (RR) of high-to-low SM/LB density was calculated at T4 and T5. RESULTS: Comparing groups A and B, VDA determined an increase in the intake of weakly cariogenic food (p < 0.05) and a decrease in that of intermediately cariogenic food (p < 0.05). After VWDA, a statistically significant increase in intake of weakly cariogenic food and a statistically significant decrease in the RR of high-density SM/LB colonies occurred in both groups. At T5, group A showed less intake of highly cariogenic food than did group B (p = 0.05) and persistent, although non-significant, reduction in the RR of high-density SM/LB colonies. CONCLUSIONS: Reinforcement measures on behavioural changes towards a noncariogenic diet not only help maintain long-lasting, healthier eating habits, but also decrease the cariogenic bacterial load in the short term, which tends to persist over time.
