La Disfunción Craneomandibular (DCM) es una patología presente en niños. Este estudio ha analizado, en una muestra de 36 niños residentes en Madrid (España), la prevalencia de los factores etiológicos, así como su relación con la semiología de la DCM. Como método diagnóstico realizamos una exploración dentaria, muscular, de articulaciones témporomandibulares (ATMs), funcional y oclusal, que complementamos con un cuestionario específico. Los factores etiológicos más frecuentes fueron: la maloclusión (66,7%), el mordisqueo de uñas o bolígrafos y el uso de chupete más de 1 año (52,8% en ambos casos), seguidos de niños con personalidad nerviosa (41,7%). En el análisis estadístico hubo una relación significativa de: la lactancia artificial con el taponamiento de oídos (p=0,016) y con la ausencia de guía protrusiva (p=0,018); los traumatismos dentofaciales con las exóstosis (p=0,066); de la asimetría en la mesialización de los primeros molares definitivos con el dolor a la palpación de las ATMs (p=0, 059); de la mordida abierta anterior con el dolor a la palpación de los músculos masticatorios (p=0, 016); de la sobremordida con la ausencia de guía protrusiva (p=0,06); de la respiración bucal con el taponamiento de oídos (p=0,024); y de la presencia de enfermedad sistémica con el rechinamiento de dientes (p=0,057). Además, se halló una relación significativa de los niños con DCM severa (más de 6 síntomas/signos) y la respiración bucal (p=0,024) y la lactancia artificial (p=0,44). Abstract The craniomandibular dysfunction (CMD) is a pathology present in children. This study has analyzed in a sample of 36 children residing in Madrid (España), the prevalence of the etiological factors, as well as its relation with CMD semiology. As diagnostic method we performed dental and muscular examination, together with temporomandibular joints (TMJs) exploration, functional and occlusal examination, that we completed with our specific questionnaire. The most frequent etiological factors were: malocclusion (66,7%), nail and pen biting and pacifier sucking over 1 year old (52,8% in both cases), and kids with nervous personality (41,7%). In the statistic analysis, there was a significant relation between: bottle feeding and fullness in the ears (p=0,016) and also the lack of protrusive guide (p=0,018); dentofacial traumas and exostoses (p=0,066); the asymmetry in the mesialization of the first permanent molars and TMJ tenderness on palpation (p=0,059); anterior open bite and masticatory muscles tenderness on palpation (p=0,016); overbite and lack of protusive guide (p=0,06); mouth breathing and fullness in the ears (p=0,024); presence of sistemic desease and teeth grinding (p=0,057). In addition, a significant relation was found between children with severe CMD (more than 6 signs/symptoms) and mouth breathing (p=0,024) and bottle feeding (p=0,44). Key Words: Craniomandibular dysfunction, temporomandibular disorders, children.

Neurophysiological Data

Introduction. Ethiopathogenesis of dysfunction and pain in temporomandibular joints has been the subject of passionate discussions between supporters of purely mechanical conception and the ones who are supporters of psyhosomatic conception. The aim of the study: Relying on neurophysiological data, the authors are trying to reveal the main role of reticular mesencephalical formation in mechanisms which provoke craniomandibular dysfunctions and confront the influence of emotional factors from neocortex and painful stimuli from oral structures. Discussion. From dynamical point of view, not only the morphological aspects of teeth and arcades, but also sensitive-sensorial mechanisms connected to masticatory muscles, periodontal structures and oral structures, should be considered. The ideal bite and perfect morphology of tooth arcades are not enough for reconstitution of correct occlusion, if there are no neuromuscular system, temporomandibular joint, and especially central nervous system. Conclusion. The presence of pain is just one of the craniomandibular dysfunction symptoms, but if it is added to the other clinical signs and emotional or affect - provoking factor, it will provoke dysfunctional syndrome.

Patient Will

The loss of anterior teeth has serious functional, esthetic disabilities, in addition to compromising the patients' quality of life. Various etiologies can be attributed to the anterior tooth loss, including trauma, caries, and periodontal diseases. The chronic mouth breathing due to nasal adenoids is known to enhance the gingival and periodontal diseases. The dental literature proves the association of nasal breathing, tongue thrusting, and anterior open bite. Arch shape and tooth position are primarily determined by the equilibrium of the forces from tongue and perioral musculature. Increased force from tongue musculature in the tongue thrusting patient leads to flaring of anterior teeth, making them susceptible for periodontal and traumatic tooth loss. Replacement of the anterior teeth in this patient will also help in restoration of anterior guidance, which is critical for the health of temporomandibular joint, posterior teeth, and musculature.

OBJECTIVES: To correct dental origin anterior crossbite by placement of Glass Ionomer cement occlusal stops on mandibular first permanent molars for maximum of two weeks. METHODOLOGY: 16 patients (age: 7-11 years) with dental anterior crossbite were treated by placement of Glass Ionomer cement occlusal stops on mandibular first permanent molars for maximum of 2 weeks to create 1mm anterior open bite. The patients were then recalled after 1 month, 3 months and 6 months for follow up visits. Fisher’s exact test applied using SPSS version # 25. RESULTS: 13 out of 16 patients were treated successfully within two weeks of placement of occlusal stops. Follow-up at six months showed no relapse in any of the corrected cases. CONCLUSION: Placement of glass ionomer cement occlusal stops for two weeks on mandibular first permanent molars is an easy approach to correct dental anterior crossbite.

ABSTRACT Objective: To evaluate the effectiveness of play strategies to break the pacifier-sucking habit and induce self-correction of the anterior open bite in the primary dentition. Methods: Data collection took place at the Pediatric Dentistry clinic of a public education institution. Three children, aged between 3 and 4 years old, using a pacifier and presenting with a 2 to 5 mm anterior open bite, participated in the research. Pediatric dental guidance was imparted to educate the family and to provide play strategies for the child by means of an illustrated book about the pacifier fairy. Results: After the first consultation, two children quit their pacifier habit. Subsequent consultations were devoted to positive reinforcement and follow-up of the self-correction of the anterior open bite. The third child required four visits to stop the pacifier habit, but other habits persisted and the open bite was only corrected after intervention by a multidisciplinary team. Conclusions: After receiving orientation from the professionals, the parents/guardians cooperated in stimulating the child, and the play activities were effective in encouraging the child to stop sucking on the pacifier, permitting self-correction of the anterior open bite. Bottle feeding, tongue interposition and mouth breathing may hinder the spontaneous correction of the anterior open bite after the pacifier habit is abandoned, requiring multidisciplinary intervention.

ABSTRACT Objective: The objective of this study was to assess the external apical root resorption (EARR) of the maxillary posterior teeth after intrusion with miniscrews. Methods: Fifteen patients (13 females and 2 males) with age ranging from 14.5 to 22 years (mean 18.1 ±2.03 years) were selected to participate in this study. All patients presented with anterior open bite of 3 mm or more. An intrusion force of 300 g was applied on each side to intrude the maxillary posterior teeth. Cone beam computed tomography (CBCT) scans were taken pretreatment and post-intrusion and were analyzed to evaluate the EARR. Results: The maxillary posterior teeth were intruded in average 2.79 ± 0.46 mm (p< 0.001) in 5.1 ± 1.3 months, and all examined roots showed statistically significant EARR (p< 0.05) with an average of 0.55 mm, except the distobuccal root of the left first permanent molars and both the palatal and buccal roots of left first premolars, which showed no statistically significant changes. Conclusions: The evaluated teeth presented statistically significant EARR, but clinically, due to the small magnitude, it was not considered significant. Moreover, the CBCT provided a good visualization of all roots in all three planes, and it was effective in detecting minimal degrees of EARR.

Aim: To evaluate the clinical behavior of sucking habits in children between 2 to 6 years old in a private (A1) and a public school (A2) in the state of Piauí. Methods: It was cross-sectional and quantitative study in 340 participants, 169 in A1 and 171 in A2. The researchers asked the children evaluated to keep their teeth occluded while analyzing whether there was no contact between the anterior teeth and no lip sealing, characterizing the anterior openbite for G1 or if there was contact between the incisors, with lip sealing, characterizing the control group (G2). Results: There was no statistically significant difference between groups regarding bottle feeding at main meals (χ2 = 3.03; p = 0.08). However, regarding the use of a pacifier, there was a statistically significant association (χ2 = 17.99; p <0.01) between pacifier use and the presence of anterior openbite. Such association was also observed between digital sucking habit and malocclusion (χ2 = 8.99; p = 0.01). Only the parents of the children with anterior openbite noticed the disharmony in the occlusion. It can be deduced that there was an awareness of parents /guardians about the disharmony generated by non-nutritive sucking habits. Conclusion: Nonnutritive sucking habits influenced the appearance of the anterior open bite in children with deciduous dentition. Nonnutritive sucking habits, such as digital sucking and pacifiers, are significantly associated with the presence of anterior open bite. Breastfeeding is important in preventing this malocclusion.

Abstract Background Due to the multifactorial aetiology and unpredictable long-term stability, skeletal anterior open bite (SAOB) is one of the most intractable conditions for orthodontists. The abnormal orofacial myofunctional status (OMS) may be a major risk factor contributing to the development and relapse of SAOB. This study is aimed at evaluating the OMS and the efficacy of orofacial myofunctional therapy (OMT) alone for SAOB subjects. Methods Eighteen adolescents with SAOB (4 males, 14 females; age: 12–18 years) and eighteen adolescents with normal occlusion (2 males, 16 females; age: 12–18 years) were selected. The electromyographic activity (EMGA) associated with mastication and closed mouth state was measured. Lateral cephalography was used to evaluate craniofacial morphology. Wilcoxon signed rank tests and t-tests were performed to evaluate myofunctional and morphological differences. Pearson or Spearman correlation analysis was used to investigate the correlations between EMGA and morphological characteristics. SAOB subjects were given OMT for 3 months, and the EMGA was compared between before and after OMT. Results During rest, anterior temporalis activity (TAA) and mentalis muscle activity (MEA) increased in SAOB subjects, but TAA and masseter muscle activity (MMA) decreased in the intercuspal position (ICP); and upper orbicularis activity (UOA) and MEA significantly increased during lip sealing and swallowing (P < 0.05). Morphological evaluation revealed increases in the FMA, GoGn-SN, ANS-Me, N-Me, L1-MP, U6-PP, and L6-MP and decreases in the angle of the axis of the upper and lower central incisors and OB in SAOB subjects (P < 0.05). TAA, MMA and anterior digastric activity (DAA) in the ICP were negatively correlated with vertical height and positively correlated to incisor protrusion. MEA was positively correlated with vertical height and negatively correlated with incisor protrusion; and the UOA showed a similar correlation in ICP, during sealing lip and swallowing. After SAOB subjects received OMT, MEA during rest and TAA, MMA and DAA in the ICP increased, while UOA and MEA decreased (P < 0.05). Conclusion SAOB subjects showed abnormal OMS features including aberrant swallowing patterns and weak masticatory muscles, which were interrelated with the craniofacial dysmorphology features including a greater anterior facial height and incisor protrusion. Furthermore, OMT contributes to OMS harmonization, indicating its therapeutic prospect in SAOB.
