RESUMEN
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.

OBJECTIVE: To compare the body mass index (BMI) and the weight loss (WL) in patients with dentofacial deformities who underwent monomaxillary versus bimaxillary orthognathic surgery. MATERIALS AND METHODS: This prospective longitudinal study included 69 patients with dentofacial deformities who underwent surgical orthodontic treatment. Patients were divided into two groups according to the type of orthognathic surgery: monomaxillary or bimaxillary. A preoperative nutritional assessment based on BMI was performed; the percentage of involuntary WL between the preoperative and postoperative periods was also calculated. Data were collected at preoperative and 10, 40, and 90 days postoperative (PO). Statistical analysis was performed using SPSS 17.0 (IBM Corp., Armonk, NY, USA), and data are reported with 95% confidence interval. RESULTS: According to BMI, patients who underwent monomaxillary surgery presented: underweight = 2.6%, normal weight = 51.3%, overweight = 35.9%, and obese = 10.3%. The subjects who underwent bimaxillary surgery presented: normal weight = 43.3%, overweight = 36.7%, and obese = 20%. BMI was similar between the groups at all time points (preoperative, p= 0.237; 10 days PO, p= 0.325; 40 days PO, p= 0.430; and 90 days PO, p= 0.609). All patients lost weight postoperatively, and WL was similar among the PO measurements (p= 0.163). CONCLUSIONS: Although both monomaxillary and bimaxillary orthognathic surgeries resulted in WL and lower BMI, there was no statistically significant difference in these metrics between the two types of surgery.

RESUMO Objetivo: Comparar o Índice de Massa Corporal (IMC) e a perda de peso (PP) de pacientes com deformidades dentofaciais após cirurgia ortognática monomaxilar e bimaxilar. Material e Métodos: Foi realizado um estudo longitudinal prospectivo em 69 pacientes com deformidade dentofacial submetidos a tratamento cirúrgico-ortodôntico. Os pacientes foram divididos em dois grupos: cirurgia ortognática monomaxilar e bimaxilar. Foi realizada avaliação nutricional pré-operatória de acordo com o IMC. Foi calculada a porcentagem de PP involuntária entre o pré e o pós-operatório (PO). A coleta de dados foi realizada no pré-operatório e aos 10, 40 e 90 dias PO. A análise estatística foi realizada no software SPSS v. 17.0, com intervalo de confiança de 95%. Resultados: De acordo com o IMC, os indivíduos submetidos à cirurgia monomaxilar apresentaram: baixo peso = 2,6%, peso normal = 51,3%, sobrepeso = 35,9% e obesidade = 10,3%. Entre os indivíduos submetidos à cirurgia bimaxilar, 43,3% estavam com peso normal, 36,7% estavam com sobrepeso e 20% eram obesos. O IMC foi semelhante em todos os períodos (pré-operatório, p= 0,237; 10 dias PO, p= 0,325; 40 dias PO, p= 0,430; e 90 dias PO, p= 0,609). Todos os pacientes perderam peso no pós-operatório. A PP foi semelhante entre os tempos de PO (p= 0,163). Conclusões: A cirurgia ortognática monomaxilar ou bimaxilar pode causar redução do peso corporal e diminuição no IMC, mas não há diferença estatisticamente significativa entre esses dois tipos de cirurgia em relação à PP e ao IMC.
RESUMEN
The maxilla is formed by the medial nasal and maxillary processes fusion. The dental lamina develops from 2 origins connecting in the lateral incisor. The maxillary lateral incisor region is often affected by dental anomalies and clefting. It is possible that genes involved in oral cleft could also be associated with a variety of phenotypic variations in the maxillary lateral incisor. In this phenotype-genotype study, we explored the association between polymorphisms in the oral-cleft-related genes BMP2 and BMP4 and root curvature of maxillary lateral incisors.Cross-sectional study.Universities and private clinics.Panoramic radiographs and DNA from 231 patients were analyzed.Schneider method (1971) was applied to estimate the degree of root curvature of the maxillary lateral incisors and to classify the root as straight (5° or less) or curved (higher than 5°). Genetic polymorphisms in BMP2 (rs235768 and rs1005464) and BMP4 (rs17563) were genotyped. Statistical analysis was performed.A total of 401 teeth (199 left and 202 right) were evaluated. Genetic analysis demonstrated trends toward association for the rs1005464 in BMP2 (P = .025) in co-dominant model and in dominant model (P = .026) for left incisors. The rs235768 in BMP2 showed trends toward association with the degree of root curvature in left incisors in the recessive model (P = .031). rs17563 in BMP4 also showed trends toward association with the degree of the root curvature in left incisors (P = .019).BMP2 (rs235768 and rs1005464) and BMP4 (rs17563) might be involved in maxillary lateral incisor root curvature.
RESUMEN
Objective: To evaluate the association of bruxism phenotypes with single nucleotide polymorphisms in FKBP5, DRD2, ANKK1, and COMT.Methods: Clinical oral examination was performed to diagnose bruxism phenotypes in 150 children. DNA was collected from saliva. Logistic univariate regression, Chi-square, and Fisher's exact tests were performed (p < 0.05).Results: Bruxism was associated with DRD2 (p = 0.02). Tooth grinding while awake was associated with ANKK1 (p < 0.001), and tooth grinding while asleep was associated with DRD2 in the additive (p = 0.030) and dominant (p = 0.008) model. Tooth clenching while awake was associated with ANKK1 in the additive (p = 0.005) and dominant (p = 0.008) models, whereas tooth clenching while asleep was associated with ANKK1 (p < 0.001) and with COMT in the additive (p = 0.001) and dominant (p = 0.003) models.Discussion: Polymorphisms in DRD2, ANKK1, and COMT are associated with bruxism phenotypes.

OBJECTIVE: The aim of the study was to assess the quality of life (QOL), oral health-related QOL (OHRQOL), temporomandibular disorders (TMDs), and psychological factors in patients with skeletal Class III malocclusion with cleft lip and palate (CLP) and without CLP. DESIGN: Case-control. SETTING: Primary care, institutional practice. PATIENTS: One hundred thirty-six patients with skeletal Class III malocclusion with CLP (n = 68) and without CLP (n = 68). MAIN OUTCOME MEASURES: QOL and OHRQOL were assessed using the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire and the Oral Health Impact Profile-14 questionnaire, respectively. TMDs and psychological factors were assessed using the Research Diagnostic Criteria for TMD (RDC/TMD). RESULTS: No differences in QOL were found between the groups (P > 0.05). Patients with CLP reported a better OHRQOL (P = 0.025) in the physical pain, physical disability, and psychological disability domains (P < 0.05). Patients with CLP presented with less myofascial pain (OR, 0.28; 95% CI, 0.11-0.71] and other articular conditions (OR 0.24; 95% CI 0.06-0.90]. More patients with CLP reported no chronic pain (P = 0.012). The QOL of patients with CLP with no depression or with no nonspecific physical symptoms including pain (NSPSIP) was better than that of patients without CLP. The OHRQOL of patients with CLP without TMDs or no psychological factors was better than that of patients without CLP. CONCLUSIONS: Patients with skeletal Class III malocclusion who require orthognathic surgery with CLP have better OHRQOL and present with fewer TMDs than those patients without CLP.

Introduction: This study aimed to evaluate if single nucleotide polymorphisms (SNPs) in runt-related transcription factor 2 (RUNX2) and bone morphogenetic protein 2 (BMP2) are associated with different craniofacial patterns. Furthermore, we also investigated if RUNX2 and BMP2 expression in the maxilla and mandible are differently expressed according to facial phenotypes and influenced by the SNPs in their encoding genes. Orthognathic patients were included. Materials and Methods: Lateral cephalometric radiographs were used to classify facial phenotypes based on Steiner's ANB and Ricketts' NBa-PtGn angles. Bone samples from 21 patients collected during orthognathic surgery were used for the gene expression assays. DNA from 129 patients was used for genotyping the SNPs rs59983488 and rs1200425 in RUNX2 and rs235768 and rs1005464 in BMP2. The established alpha was 5%. Results: A statistically significant difference was observed in the relative BMP2 expression in the mandible between Class I and III participants (P = 0.042). Homozygous GG (rs59983488) had higher RUNX2 expression (P = 0.036) in the mandible. In maxilla, GG (rs1200425) had a higher BMP2 expression (P = 0.038). Discussion: In conclusion, BMP2 is expressed differently in the mandible of Class I and Class III participants. Genetic polymorphisms in RUNX2 and BMP2 are associated with their relative gene expression.
RESUMEN
Oronasal fistula (ONF) is the most common complication after palatoplasty in patients with cleft lip and palate (CLP). When left untreated, it may negatively affect the quality of life, leading to development of other comorbidities. This study reports for the first time, the use of a portion of a hyperplasic tissue associated with pedicled buccal fat pad flap to repair a large anterior ONF in a 60-year-old man. The hyperplasic tissue may have developed due to the combination of a loose fitting upper denture and long-term use of dihydropyridine calcium channel blocker (amlodipine besylate). There is controversy in the literature about use of pedicled buccal fat pad flap in the anterior region. However, in this study, we report successful repair of a large anterior ONF using a portion of a fibroepithelial hyperplasic tissue associated with pedicled buccal fat pad flap.

The aim of this study was to report two rare cases of ectopic tooth into the nasal cavity. The first case reports a 32-year-old female patient with the main complaint of having a tooth inside her nose. According to her, this condition causes pain and sporadic nosebleed. The patient had a facial trauma when she was 6 years old. The second case refers to an 8-year-old girl with left incomplete unilateral cleft lip and palate. The main complaint was left-sided nasal obstruction by a white hard mass. The treatment for both cases was surgical removal of the ectopic erupted tooth under general anesthesia. In conclusion, we can state that the surgical removal of intranasal tooth is a safe procedure and improves patient's quality of life.
