Abstract
OBJECTIVE This study evaluated the efficacy of Valeriana officinalis L. and Passiflora incarnata L. to control anxiety, surgical discomfort, and changes in vital signs of patients undergoing extraction of two unilateral third molars. MATERIALS AND METHODS This study is a randomized, triple-blinded clinical trial. Fifty-four patients were allocated into three groups (Valeriana officinalis L., Passiflora incarnata L., and placebo). Anxiety levels were assessed using the State-Trace Anxiety Inventory (STAI) index, surgical discomfort using the QCirDental, and through the measurement of vital signs. The surgical times evaluated were before (T0), during (T1), and after surgery (T2). RESULTS There was evidence that both Valeriana officinalis L. and Passiflora incarnata L., reduced STAY-S scores between T0 and T2 (p < .05), unlike placebo (p = .129). There was no change in surgical discomfort in all groups over time, and vital signs presented variable results. CONCLUSION Phytotherapy drugs showed a reduction in anxiety state compared to the placebo group during third molar extraction procedure. CLINICAL TRIAL REGISTRATION: klRBR-6kcxvrc, March 10, 2022.

Abstract
PURPOSE Evaluate which factors compromise patients' quality of life who have undergone orthognathic surgery in the pre and postoperative period of 2 years. STUDY DESIGN In this longitudinal prospective study, 46 adult patients undergoing orthognathic surgery were evaluated. The primary outcome variable was quality of life, assessed using the overall score of the orthognathic quality of life questionnaire (OQLQ) in the pre and 2-year postoperative periods. The predictor variables were axis I (temporomandibular dysfunction) and axis II (psychosocial) RDC/TMD diagnoses, assessed preoperatively and 2 years postoperatively; profile, asymmetry, and open bite preoperatively; and orthodontic treatment active 2 years postoperatively. The covariables were age and sex. The OQLQ score was compared preoperatively and postoperatively using the Wilcoxon test and with the other variables using the Mann-Whitney and Kruskall-Wallis tests. RESULTS Preoperatively, higher OQLQ scores were associated with myofascial pain (P = .012) and severe depression (P = .030). Two years after surgery, there was an improvement in overall OQLQ (P < .001), myofascial pain (P = .012) and chronic pain (P = .001). However, higher OQLQ scores were associated with individuals who had myofascial pain (P = .012), active orthodontic treatment (P = .007), and other nonspecific physical symptoms including pain (NSPSIP) (P = .049). CONCLUSION Quality of life was affected preoperatively by myofascial pain and depression, and although it improved significantly 2 years after surgery, it continued to be affected by myofascial pain, NSPSIP, and active orthodontic treatment.

Abstract
UNLABELLED Orthognathic patients with skeletal class II malocclusion frequently suffer from myofascial pain (MP). PURPOSE This study aimed to evaluate the prevalence and associated factors of MP in these patients. METHODS This cross-sectional study was performed in adult patients with skeletal Class II malocclusion requiring orthognathic surgery. They were divided according to the presence or absence of MP. The predictor variables were craniofacial morphology, sex, temporomandibular disorders, chronic pain, depression, and polymorphisms of dopamine receptors DRD2 (rs6275 and rs6276) and ANKK1 (rs1800497) genes. Data were submitted to statistical analyses using the linear regression model and Poisson regression with a significance level of 0.05. RESULTS Sixty-five individuals were selected, of which 50 (76.92%) were females. A total of 21 (32.3%) patients had MP. Individuals with MP showed a decrease in the mandible gonial angle (p = 0.042) and an increased risk of having temporomandibular joint (TMJ) disc displacement (p = 0.003), TMJ pain (p = 0.030), chronic pain (p = 0.001), and severe depression (p = 0.015). Additionally, individuals carrying AA and AG genotypes in rs6275, and CC genotype in rs6276, were more likely to have MP (p < 0.05). CONCLUSION In this study, 32.3% of skeletal class II orthognathic patients had MP, which was associated with a decreased gonial angle, TMJ disc displacement, TMJ pain, chronic pain, depression, and polymorphisms in the DRD2 gene.

Abstract
This study aimed to evaluate the associations between oral health-related quality of life (OHRQoL) and patient-associated factors and polymorphisms in the estrogen receptor 1 (ESR1) and 2 (ESR2) genes in patients with dentofacial deformities (DFD). This cross-sectional study included 234 adult individuals. Data such as age, sex, and the type of facial profile (I, II, or III), were collected, and the short-form oral health impact profile 14 (OHIP-14) questionnaire was used to assess their OHRQoL. DNA was collected from oral mucosa cells, and the polymorphisms in ESR1 (rs2234693 and rs9340799) and ESR2 (rs1256049 and rs4986938) were evaluated using real-time polymerase chain reaction. The data were subjected to statistical analysis at a significance level of 5%. Individuals over 28 years of age exhibited worse OHRQoL (p = 0.003) than individuals aged less than or equal to 28 years. Women had worse OHRQoL than men (p < 0.001). Profile II individuals had worse OHRQoL in the social disability domain than profile III individuals (p = 0.030). Genetic analysis showed that rs9340799 was associated with OHRQoL in the functional limitation domain, and GG individuals exhibited worse OHRQoL than individuals carrying the AA/AG genotypes (p < 0.030). In the social handicap domain, individuals with GG genotype in rs9340799 exhibited worse OHRQoL than AG individuals (p < 0.043). Collectively, our results reveal that factors including age, sex, and type of facial profile, are associated with OHRQoL in patients with DFD. In addition, individuals with the GG genotype in rs9340799 (ESR1) may experience a negative impact on OHRQoL in the functional limitation and social handicap domains.

Abstract
The objective of this study was to evaluate if individuals with dentofacial deformities (DFD) who require orthognathic surgery are affected more by depression and pain. A case-control study was performed with 195 individuals. In the DFD group, 145 individuals with Class II and III malocclusion requiring orthognathic surgery were selected. The control group was composed of 50 individuals with no DFD. All patients were diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Data were analyzed with a significance level of 0.05. The DFD group more often presented severe depression (p = 0.020) and chronic pain (p = 0.017). They also presented higher prevalence of Nonspecific Physical Symptoms Including Pain (P = 0.002) and Nonspecific Physical Symptoms Excluding Pain (p = 0.002). Concerning TMD symptoms, the DFD group had more myofascial (p = 0.002) and articular pain (p = 0.041). Therefore, the results of this study suggest that depression and pain are more common in individuals with DFD requiring orthognathic surgery compared with individuals without DFD.

Abstract
OBJECTIVE The objective of this study was to evaluate the association between SLC6A4 (rs1042173 and rs3813034), DRD2 (rs6275 and rs6276), ANKK1 (rs1800497), and COMT (rs174675) genetic polymorphisms and alterations in anxiety levels and vital signs in individuals undergoing third molar extractions. STUDY DESIGN One hundred sixty-eight individuals were evaluated at the pre-, trans-, and postoperative periods by checking systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and body temperature. Anxiety levels were assessed using the State-Trait Anxiety Inventory (STAI). Buccal mucosa cells were collected for genetic evaluation using real-time polymerase chain reaction. Statistical analysis was performed at a significance level of 5%. RESULTS The level of anxiety was associated with rs1800497 for STAI-Trait (P = .031) and rs174675 for STAI-State (P = .007). Considering the vital signs, there was a significant difference between the values of respiratory rate and rs1042173 (P = .029), rs3813034 (P = .024), and rs6275 (P = .025). The diastolic blood pressure values differed significantly for rs1042173 (P = .042), and the body temperature values differed significantly for rs174675 (P = .016). CONCLUSIONS Polymorphisms in SLC6A4, DRD2, ANKK1, and COMT genes could be associated with alterations in anxiety levels and vital signs in individuals undergoing third molar extractions.

Abstract
OBJECTIVE The aim of the study was to evaluate the association between genetic polymorphisms in RUNX2, BMP4, BMP2, TGFβ1, EGF, and SMAD6 and variations in permanent tooth size (TS). MATERIALS AND METHODS This cross-sectional study evaluated 110 individuals' dental casts to determine the maximum tooth crown size of all fully erupted permanent teeth (third molars were excluded) in the mesiodistal (MD) and buccolingual (BL) dimensions. Genomic DNA was obtained from the epithelial cells of the oral mucosa to evaluate the genetic polymorphisms in RUNX2 (rs59983488 and rs1200425), BMP4 (rs17563), BMP2 (rs235768 and rs1005464), TGFβ1 (rs1800470), EGF (rs4444903), and SMAD6 (rs2119261 and rs3934908) through real-time PCR. The data were submitted to statistical analysis with a significance level of 0.05. RESULTS The genetic polymorphisms rs59983488, rs1200425, rs17563, rs235768, rs1005464, rs1800470, and rs4444903 were associated with MD and BL TS of the upper and lower arches (p < 0.05). The polymorphism rs2119261 was associated with variation in TS only in the upper arch (p < 0.05). The rs3934908 was not associated with any TS measurement (p > 0.05). CONCLUSIONS In summary, this study reports novel associations between variation in permanent TS and genetic polymorphisms in RUNX2, BMP4, BMP2, TGFβ1, EGF, and SMAD6 indicating a possible role of these genes in dental morphology. CLINICAL RELEVANCE Polymorphisms in odontogenesis-related genes may be involved in dental morphology enabling a prediction of permanent TS variability. The knowledge regarding genes involved in TS might impact the personalized dental treatment, considering that patients' genetic profile would soon be introduced into clinical practice to improve patient management.

Abstract
OBJECTIVES To evaluate, longitudinally, the impacts of orthognathic surgery in patients with skeletal class II malocclusion on oral health-related quality of life (OHRQoL), temporomandibular disorders (TMD) and psychological symptoms. MATERIALS AND METHODS Forty-three patients with skeletal class II malocclusion who were submitted to orthognathic surgery were evaluated during their preoperative and postoperative periods. They answered the short version of the Oral Health Impact Profile (OHIP-14) and were also diagnosed according to Axes I and II of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The evolution of OHRQoL and TMD before and after surgery was verified, and the relationships among these variables were found through statistical analysis using Wilcoxon, McNemar, chi-square, and Mann-Whitney tests, with a 5% significance level. RESULTS The median of the overall OHIP-14 score and five domains decreased after orthognathic surgery (p < 0.05), the functional limitation domain increased (p = 0.014), and the physical disability domain did not show an association (p = 0.133). There were improvements in articular pain (p = 0.016), chronic pain (p = 0.019), and nonspecific physical symptoms excluding pain (p = 0.013). In addition, an association was found between poorer OHRQoL (overall scale and domains) and the Axis II variables of the RDC/TMD (p < 0.05). CONCLUSION Orthognathic surgery improved perceived OHRQoL, articular pain, and chronic pain. The conditions of Axis II of the RDC/TMD interfered with OHRQoL postoperatively. CLINICAL RELEVANCE Although orthognathic surgery improves QoL and some TMD conditions in skeletal class II patients, poorer postoperative outcomes are observed when psychological conditions are present.

Abstract
The aim of this study was to evaluate patient perception of surgical discomfort in third molar surgery and the association with clinical variables and polymorphisms associated with the FKBP5, SLC6A4, and COMT genes. This cross-sectional observational study was carried out on 196 participants aged between 18 and 64 years at the Federal University of Paraná in 11 months. The intensity of surgical discomfort was assessed using the QCirDental questionnaire. Data on surgical and individual procedures were also cataloged. The oral health related quality of life was assessed by the Oral Health Impact Profile questionnaire (OHIP-14). The DNA sample was obtained from cells of the oral mucosa. Five markers of the FKBP5, SLC6A4, and COMT genes were genotyped. The data were submitted to statistical analysis with a significance level of 5%. Women reported greater intensity of discomfort associated with third molar surgery compared to men (p = 0.001). In the recessive model, the AA genotype of the rs3800373 marker was associated with greater surgical discomfort (p = 0.026). Therefore, women and individuals of the AA genotype for the rs3800373 marker in the FKBP5 gene reported greater surgical discomfort associated with third molar surgery.

Abstract
Objective: To evaluate if temporomandibular disorders (TMDs) are associated with genetic polymorphisms in ESR1 and ESR2, which are genes encoding oestrogen receptor alpha (ERα) and beta (ERβ). Also, we included an animal model to check if ERα and ERβ are expressed in the temporomandibular joint (TMJ) during adolescence.Materials and methods: A total of 139 teenagers and 93 adults were diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMDs). The DNA was collected and the markers ESR1 and ERS2 were genotyped. Additionally, immunohistochemistry was performed in TMJ tissues from female Wistar rats during puberty. All data were submitted to statistical analysis with confidence interval of 95%.Results: Teenagers presented more disc displacement and arthralgia than adults (p < .05). The genetic polymorphism rs1256049 in ESR2 was associated with disc displacement (p = .040; OR = 10.50/95%CI 1.17-98.74) and arthralgia (p = .036; OR = 7.20/95%CI 1.10-46.88) in adults. The ERα and ERβ are expressed in rat TMJ tissues.Conclusions: We provide evidence that ESR2 is associated with TMD and could be a genetic marker for this condition in adult women. Furthermore, oestrogens receptors are presented in TMJ of adolescent female rats.

Abstract
PURPOSE To identify the most prevalent types of complications associated with orthognathic surgery and its possible risk factors. METHODS This study was a retrospective investigation of records of 485 patients who underwent orthognathic surgery between 2008 and 2014 at the Oral and Maxillofacial Surgery Service at the Federal University of Paraná, Curitiba, Brazil. Types of complications were recorded. Independent variables such as sex, age, duration of surgery and hospitalization, number of surgeries, surgical site, and types of osteotomy performed were evaluated. Complications were also evaluated based on the treatment according to the Clavien-Dindo Classification. Data were submitted to statistical analysis with a significance level of 0.05. RESULTS A total of 93 complications were reported (19.2%), including postoperative malocclusion, hemorrhage, inferior alveolar nerve injury, bad split, and infection. Complications were more common in men (p = 0.029). The number of complications was higher in surgeries that took more time to perform (p < 0.05) when the entire sample was taken into consideration. The prevalence of complications was related to a higher number of procedures per surgery (p = 0.019). Complications were more frequent in mandibular procedures (p = 0.010), particularly in bilateral sagittal split osteotomies (p < 0.001). Related to treatment, Clavien-Dindo grade I complications were the most frequent (72.04%). There was no association between sex, age, surgery duration, length of hospitalization, or surgical site with complication grades according to the Clavien-Dindo classification (p ≥ 0.05). CONCLUSION Postoperative malocclusion, hemorrhage, inferior alveolar nerve injury, bad split and infection are the most prevalent complication in orthognathic surgery. They seem to be related to sex, duration of surgery, number of surgeries, surgical site, and the type of osteotomy performed. With these in mind, it is possible to explain to the patient the different levels of severity of complications related to the surgery.

Abstract
INTRODUCTION Cementoblastoma is a rare and benign odontogenic mesenchymal tumor, often characterized by the formation of cementum-like tissue produced by neoplastic cementoblasts attached to or around the roots of a tooth. CASE REPORT 22-year-old male patient was referred to the Federal University of Paraná after occasional finding on a routine panoramic radiograph. Clinical examination suggested no alterations. Medical and family history presented no alterations as well. Computed tomographic (CT) showed the presence of a radiopaque area associated with the roots of the impacted third molar measuring 15 mm × 10 mm inside the left maxillary sinus. The treatment plan suggested was to surgically remove it under general anesthesia. An intraoral approach was conducted, using the Newmann incision from the superior left first molar to the retromolar area with anterior and posterior relaxant incisions. Using a Caldwell-Luc access next to the maxillary tuberosity region, the maxillary sinus was exposed and the calcified mass attached to the roots of the tooth was reached. Pathological mass removed was sent for histopathological investigation. Examination revealed dense, mineralized, cementum-like material and vascular soft tissue areas that consisted of cementoblasts. One-year follow-up shows no recurrence and absence of symptoms.

Abstract
OBJECTIVE This study aimed to evaluate the association of genetic variants inACTN3 and MYO1H with craniofacial skeletal patterns in Brazilians. DESIGN This cross-sectional study enrolled orthodontic and orthognathic patients selected from 4 regions of Brazil. Lateral cephalograms were used and digital cephalometric tracings and analyzes were performed for craniofacial phenotype determination. Participants were classified according to the skeletal malocclusion in Class I, II or III; and according to the facial type in Mesofacial, Dolichofacial or Brachyfacial. Genomic DNA was extracted from saliva samples containing exfoliated buccal epithelial cells and analyzed for genetic variants inACTN3 (rs678397 and rs1815739) and MYO1H (rs10850110) by real-time PCR. Chi-square or Fisher's exact tests were used for statistical analysis (α = 5%). RESULTS A total of 646 patients were included in the present study. There was statistically significant association of the genotypes and/or alleles distributions with the skeletal malocclusion (sagittal skeletal pattern) and facial type (vertical pattern) for the variants assessed inACTN3 (P < 0.05). For the genetic variant evaluated in MYO1H, there was statistically significant difference between the genotypes frequencies for skeletal Class I and Class II (P < 0.05). The reported associations were different depending on the region evaluated. CONCLUSION ACTN3 and MYO1H are associated with sagittal and vertical craniofacial skeletal patterns in Brazilian populations.

Abstract
This study aimed to compare the biomechanical stability of the fixation of mandibular sagittal split osteotomy of the ramus by two types of titanium miniplates in sheep mandibles. Seven preserved sheep mandibles with similar weight and size were selected, dissected with complete removal of soft-tissue structures, and sectioned in their midline. After performing sagittal split osteotomy, 5 mm of advancement was standardized and samples were divided into two groups according to the type of titanium miniplate (GI = seven hemimandibles were fixed with straight titanium miniplate, GII = seven hemimandibles were fixed with L-shaped titanium miniplates), and then subjected to compressive load. The means (standard deviation) of the compressive load and extension values were 70.68 N (22.26) and 63.36 mm (15.60) to straight miniplates, and 78.80 N (32.54) and 70.55 mm (5.42) to L-shaped miniplates. After comparison and statistical analysis, the results showed no significant difference between the two types of titanium miniplates.

Abstract
OBJECTIVE The aim of this study was to evaluate alterations in condylar positioning through submentovertex projection (Hirtz Radiographic Technique) in patients who underwent orthognathic surgery for maxillary advancement and mandibular setback with stable internal fixation. METHODS A prospective longitudinal clinical study of 40 surgical patients presenting dentofacial deformity admitted in the Oral and Maxillofacial Surgery Department of Federal University of Paraná (UFPR) in the period between March 2013 and December 2015. We performed two submentovertex digital radiographs, one 7 days before surgery and the other one 30 days after the procedure. Cephalometric tracings were made using Radiocef® Studio 2 Software and measured the intercondylar and condylar angles (right and left). RESULTS There was a decrease in the intercondylar angle (p < 0.001) and an increase in condylar angles both the right and the left side (p < 0.001) when compared with the pre and postoperative period. There was a larger increase in condylar angle on the right side in males (p = 0.007). CONCLUSION There is a tendency of decreasing of the intercondylar angle after orthognathic surgery, regardless of the alteration in the condylar angles, creating a new position of the condyle in the glenoid fossa. Patients with asymmetry may present greater alterations in the positioning of the opposite condylar to the deviation of the mandibular midline.

Abstract
Grand proportions fyssural cyst enucleated with Le Fort I osteotomy and down-fracture. The remaining space was filled with BIOSs and bioguide (lyophilized bone and collagen membrane). Patient’s follow-up presents no recurrence and favorable osseous formation.
Fissural cysts (FC) are caused by entraped epithelium between nasal and maxilar processes. They are commonly treated with surgical enucleation precedded or not by marsupialization depending on the cyst size. Biopsy of lesion is recommended due to confirm radiographic evaluation. It is rare to observe Le Fort I surgical approach to this type of injury. This study reports the case of an uncommon grand proportions fissural cyst in a female patient, 53, that was referred to the Oral and Maxillofacial Surgery Departament of Hospital XV presenting volume increase in maxilla associated with numbness of palate. Radiograph examination showed an intimate relationship between incisors apexes and FC. Expansion of both buccal and palate cortical was then confirmed as well as its unusual size, approximately 25 millimeters. Due to the abnormal size of lesion and possible impairment of upper incisors, LeFort I osteotomy associated with downfracture to cystic enucleation was the chosen treatment. After enucleation, the remaining space was filled with BIOSs and bioguide (lyophilized bone and collagen membrane). Patients’ twelve months follow-up demonstrate no relapses and maintenance of teeth involved.

Abstract
Abstract The aim of this study was to evaluate the stress and dislodgement resistance by finite element analysis of different types of fixation in mandibular orthognathic surgery. A 3D solid finite element model of a hemi-mandible was obtained. A bilateral sagittal split osteotomy was simulated and the distal segment was advanced 5 mm forward. After the adjustment and superimposing of segments, 9 different types of osteosynthesis with 2.0 miniplates and screws were simulated: A, one 4-hole conventional straight miniplate; B, one 4-hole locking straight miniplate; C, one 4-hole conventional miniplate and one bicortical screw; D, one 4-hole locking miniplate and 1 bicortical screws; E, one 6-hole conventional straight miniplate; F, one 6-hole locking miniplate; G, two 4-hole conventional straight miniplates; H, two 4-hole locking straight miniplates; and I, 3 bicortical screws in an inverted-L pattern. In each model, forces simulating the masticatory muscles were applied. The values of stress in the plates and screws were checked. The dislodgement resistance was checked at the proximal segment since the distal segment was stable because of the screen at the occlusal tooth. The regions with the lowest and highest displacement were measured. The offset between the osteotomized segments was verified by millimeter intervals. Inverted-L with bicortical screws was the model that had the lowest dislodgment and the model with the lowest tension was the one with two conventional plates. The results suggest that the tension was better distributed in the locking miniplates, but the locking screws presented higher concentration of tension.

Abstract
INTRODUCTION The present article reports the late removal of a wisdom tooth displaced into the maxillary sinus associated with the curettage of the adjacent infection tissue, under general anesthesia. CASE DESCRIPTION A male patient, 42 years-old, was forwarded to remove a right wisdom tooth which was displaced into the right maxillary sinus for 10 months. The patient reported that the tooth was tried to be removed using odontosection in two moments without any success. Since then, the patient has been having (applicants) episodes of sinusitis. It had been planned to remove the tooth and the cleaning of the right maxillary sinus. The surgical procedure was done through the Caldwell-Luc access, followed by the removal of the dental fragments which were into the maxillary sinus and curettage of the cavity in order to remove the granulation tissue, associated to copious irrigation. CONCLUSION The surgical removal of the tooth displaced into the maxillary sinus associated with the sinus curettage was successfully achieved, solving the patient complaints.

Abstract
Dental treatment and surgery is a well-established method of correcting dentofacial deformities, and such treatment has an impact on the quality of life of individuals. The objective of this study was to evaluate the effect of orthognathic surgery on the quality of life of patients receiving treatment at the Universidade Federal do Paraná - UFPR. Clinical data were evaluated for the control group, and a quality-of-life evaluation questionnaire was completed [Oral Health Impact Profile (OHIP-14)]. For the case group, the same data were gathered along with information regarding their dentofacial deformity. The OHIP-14 questionnaire was also completed at three distinct stages of the experiment. The median age in the control group was 23.5 years. In the case group, the predominant gender was female, and the mean age of patients was 29.4 years. There was a statistically significant association between gender and OHIP-14 (p< 0.001). No such association was observed between age and OHIP-14 scores (p= 0.616). In the control group the OHIP-14 median score was 11.5. In the case group, the average OHIP-14 score at was 18 at T0, 21 at T1, and 8 at T2. The results demonstrated a statistically significant association between the three time stages at which OHIP-14 was analyzed (p< 0.001). There was a smaller reduction in the negative impact for transversal deformities of the jaw when compared with other deformities. Orthognathic surgery led to a reduction in the negative effects on the quality of life of patients.

Abstract
INTRODUCTION Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment. Both modalities can affect esthetics. OBJECTIVE This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurring after orthognathic surgery for maxillary advancement. METHODS A total of 17 patients who underwent orthognathic surgery for maxillary advancement between September, 2010 and July, 2011 were selected. Exposure of maxillary central incisors was evaluated clinically and by lateral cephalograms. Measurements were taken one week before and three months after surgery. Data were paired in terms of sex, age, nasolabial angle, height and thickness of the upper lip, the amount of maxillary advancement, clinical exposure and inclination of maxillary central incisor by statistical tests (CI 95%). RESULTS After maxillary advancement, incisor clinical exposure had increased even with relaxed lips and under forced smile. Moreover, there was a mean increase of 23.33% revealed by lateral cephalograms. There was an inverse correlation between upper lip thickness and incisors postsurgical exposure revealed by radiographic images (p = 0.002). CONCLUSIONS Significant changes in the exposure of maxillary central incisors occur after maxillary advancement, under the influence of some factors, especially lip thickness.

Abstract
OBJECTIVE To evaluate the influence of orthognathic surgery on the clinical signs and symptoms of temporomandibular disorders (TMDs). STUDY DESIGN In a cohort study, 54 patients undergoing orthognathic surgery were evaluated with regard to the signs and symptoms of TMDs through subjective and objective assessments. These evaluations were performed 1 week preoperatively (T1), 1 month postoperatively (T2), and 6 months postoperatively (T3). The evaluations included patient variables and surgery. Univariate analyzes were performed to verify the association of the variables (P < .05). RESULTS The incidence of TMD 6 months after orthognathic surgery was significantly lower (P < .001). TMD intensity decreases significantly in the postoperative period. Females had a higher prevalence of TMD (P = .003) and muscular disorders preoperatively (P = .001). There was a decrease in clicks between T1 and T3 (P = .013). Mouth opening without pain worsened from T1 to T2 (P < .001) and improved from T1 to T3 (P = .015) and T2 to T3 (P < .001). The results were similar for mouth opening with pain (P < .001). In patients undergoing jaw fixation with bicortical screws, mouth opening without pain was significantly less in T3 patients than in patients undergoing fixation with plate and monocortical screws (P = .048). CONCLUSIONS Orthognathic surgery reduces the clinical signs and symptoms of TMD.

Abstract
Unilocular bone cysts are the most common entities affecting the maxillofacial region. The mechanism of proliferation and expansion remains unclear. Metalloproteinases (MMPs) are associated to diverse pathological conditions. The aim of the present study was to correlate the radiographic aspect (area) and the presence of MMP-2 and MMP-9 in dentigerous cysts, radicular cysts and keratocystic odontogenic tumors. The radiographic area of each lesion was calculated using the mathematical formula of the ellipse area. All specimens were subjected to immunohistochemical analysis for these enzymes. The average radiographic area was 284.17 mm2, 235.81 mm2 and 381.81 mm2, respectively. Statistical analyses revealed no association between the immunoreactivity of MMPs and radiographic area of the lesions in all pathologies studied, except for MMP-2 and radicular cysts, for which smaller lesions had increased immunostaining for this enzyme. The results demonstrate that quantities of MMP-2 and MMP-9 are especially involved with dentigerous and radicular cysts in expansion, whereas these enzymes seem to be related to the biological behavior of keratocystic odontogenic tumors, indicating invasion and cell proliferation. Moreover, there is an inverse association between MMP-2 and MMP-9 in keratocystic odontogenic tumors (p=0.03; rs=-0.660), indicating activity in different regions.

Abstract
AIM To describe the options of treatment to remove a sialolith associated with the submandibular gland duct in a patient with epidermolysis bullosa (EB). BACKGROUND Treatment of patients with EB is very complex and involves a multidisciplinary team. This condition is characterized by a spectrum of blistering and mechanical fragility of the skin. One main feature of this disease is the esophageal constriction and possible constriction to the submandibular duct. This alteration may induce the formation of calculi in this duct, which is called sialolith. Once the sialolith obliterates the trajectory of the duct this will lead to a sialolithiasis. The calculi have to be removed. CASE REPORT Seventeen years old female patient with dystrophic EB developed a sialolith at the submandibular duct. She has a limited mouth opening and her tongue was collapsed with mouth floor. The first choice of treatment was the lithotripsy, once this procedure is less invasive and a surgical remove could worse the collapsed tongue. She was with acute pain and with a great augmentation in the submandibular area. Once the patient was debilitated and has difficult to swallow she invariably needed to be hospitalized in order to receive intravenous medication. During the hospitalization the sialolith could be seen through the opening of the duct and the calculi was removed with local anesthesia. CONCLUSION The treatment of sialolithiasis usually does not present major challenges, nevertheless if the sialolithiasis is associated with EB, the treatment became an extremely challenge. In this particular case the option of treatment was the less invasive. CLINICAL RELEVANCE This case report has an enormous clinical relevance once there is no protocol to treat patients with EB and buccal diseases.

Abstract
A dentigerous cyst is a developmental odontogenic cyst that develops when fluid accumulates between the reduced enamel epithelium and the tooth crown of an unerupted tooth. Treatment modalities range from marsupialization to enucleation and are based on the premise that the pathological process can be controlled locally with minimal injury to the adjacent host structures. The purpose of this case report was to describe the diagnosis of a large expansible dentigerous cyst in an 11-year-old boy. The chosen treatment was an initial decompression to reduce the size of the osseous defect, followed by enucleation and tooth extraction.
