A literatura evidencia que a má oclusão pode se manifestar desde os estágios mais precoces do desenvolvimento oclusal, e, na maioria dos tipos morfológicos, não apresenta auto-correção nos estágios posteriores do desenvolvimento oclusal. Para que políticas públicas possam ser adotadas no sentido de incluir a ortodontia preventiva e interceptativa nos programa de saúde bucal, visando beneficiar principalmente a parte da população menos favorecida, este trabalho teve como objetivo avaliar a prevalência da má oclusão na dentição decídua na cidade de Belém-PA, examinando crianças de escolas públicas e privadas, verificando a influência do nível sócio-econômico na manifestação da má oclusão. Para tanto, foram examinadas 652 crianças, de ambos os sexos, de 3 a 6 anos de idade, na fase de dentição decídua completa, matriculadas em préescolas da rede privada e da rede pública do ensino de Belém- Pará. Foi observada uma prevalência de 81,44% de má oclusão, sendo mais frequente nas crianças do gênero feminino da rede privada (p=0.01). A má- oclusão de Classe II foi mais prevalente, seguida da Classe I e da Classe III. Dentre os diferentes tipos morfológicos de má oclusão, a sobremordida e a mordida cruzada posterior foram mais prevalentes nas crianças da rede privada, em ambos os gêneros, enquanto o trespasse horizontal aumentado e a classe II, apresentaram uma maior ocorrência nas crianças da rede privada no gênero feminino. A má oclusão de Classe I e III foram mais freqüentes nas crianças do gênero feminino na rede pública. A mordida aberta anterior e a mordida cruzada anterior, mostraram comportamento semelhante nos dois grupos de escola, em ambos os gêneros. A perda precoce de dentes decíduos foi mais prevalente (p=0.000) nas crianças da rede pública em ambos os gêneros. Assim, pode-se concluir que a ocorrência da má oclusão na dentição decídua na cidade de Belém é muito alta; que o nível sócio-econômico exerce influência sobre a manifestação das más oclusões, pois essas foram mais freqüente nas crianças da rede privada do gênero feminino e que a ocorrência da perda precoce de dentes decíduos nas crianças da rede pública ainda apresenta um índice alarmante, decorrente provavelmente de uma política de saúde pública ineficiente, que atue em nível preventivo e interceptativo.

INTRODUCTION: This study evaluated posteroanterior cephalograms before and after treatment and long term follow-up of Class II division 1 patients treated with bionator. OBJECTIVE: The objective was to demonstrate the transverse growth of maxilla and mandible during and after bionator therapy. METHODS: Measurement of transverse dimensions between posterior maxillary and mandibular implants, as well as the distances between the buccal, gonial and antegonial points were recorded. Measurements were analyzed at three periods: T1 = before bionator therapy, T2 = after bionator therapy and T3 = 5.74 years after T2. RESULTS: There was statistically significant transverse increase due to growth and/or treatment for all variables, except for the distance between the anterior maxillary implants. CONCLUSIONS: During the study period only the anterior maxillary area did not show transverse growth.

Objective: The aim of this study was to evaluate the two-year clinical performance of Class III, IV, and V composite restorations using a two-step etch-and-rinse adhesive system (2-ERA) and three one-step self-etching adhesive systems (1-SEAs).Material and Methods: Two hundred Class III, IV, and V composite restorations were placed into 50 patients. Each patient received four composite restorations (Amaris, Voco), and these restorations were bonded with one of three 1-SEAs (Futurabond M, Voco; Clearfil S3 Bond, Kuraray; and Optibond All-in-One, Kerr) or one 2-ERA (Adper Single Bond 2/3M ESPE). The four adhesive systems were evaluated at baseline and after 24 months using the following criteria: restoration retention, marginal integrity, marginal discoloration, caries occurrence, postoperative sensitivity and preservation of tooth vitality. After two years, 162 restorations were evaluated in 41 patients. Data were analyzed using the chi(2) test (p<0.05).Results: There were no statistically significant differences between the 2-ERA and the 1-SEAs regarding the evaluated parameters (p>0.05).Conclusion: The 1-SEAs showed good clinical performance at the end of 24 months.

Aim: to evaluate the association of the long face pattern and the mouth breathing, correlating them with the intraoral characteristics. Methods: the sample was composed of 60 Caucasian Brazilian descendents patients, divided in two groups according to the subjective of their facial pattern. The patients were clinically evaluated to determine their respiratory pattern and the diagnosed of malocclusion. The lateral teleradiographies were drawn in standard to verification facial cephalometric pattern. Chi-Square analysis evaluated the association between subjective facial pattern and type of breathing; facial pattern subjective and cephalometric facial pattern. It was also the chi-square with yates correction to evaluate the associations between subjective facial pattern, type of breathing and posterior cross bite; facial subjective standard, type of breathing and anterior open bite; facial pattern between subjective, type breathing and type of Angle´s malocclusion. Results: it showed that long face pattern (group 1) was associated with mouth breathing habit and facial cephalometric standard. Moreover, the long-face pattern (group 1) presented that mouth breathing was associated with a posterior crossbite and Angle Class II malocclusion. Conclusion: the long face pattern - evaluated with subjective facial analyses - was associated with mouth breathing. The long face pattern and patients with mouth breathing was associated with a posterior crossbite and Class II Angle's malocclusion.

Fixed mandibular propulsion appliances are an alternative for the treatment of Class II malocclusion in individuals with mandibular deficiency. Since they are fixed appliances, said devices keep the mandible in an anterior-forced position during rest and during all mandibular functions. When a propulsive appliance is used, the lower jaw is displaced forward and downward. This movement leads to a new position of the condyle, which can, ultimately affect the normal functioning of the temporomandibular joint (TMJ). The aim of this paper was to review effects of fixed mandibular propulsive appliance on TMJ. Inclusion criteria considered studies on animals or humans using TMJ radiography, computed tomography, and magnetic resonance imaging. Studies confirm a favorable relation between condyle and glenoid fossa following treatment with fixed mandibular propulsion appliances.

Two treatment options are available for adult patients with skeletal Class II malocclusion caused by mandibular deficiency: combined mandibular advancement surgery and orthodontic treatment or mandibular advancement appliance. This study aimed to analyze the effects of two therapeutic modalities of Class II malocclusion treatment with mandibular deficiency. Two distinct individuals with Class II malocclusion division 1 and mandibular deficiency were treated after growth spurt. The first individual used the Herbst appliance as a therapeutic option and the second individual was treated with bilateral sagittal osteotomy. The cephalometric, occlusion and face results were evaluated for both individuals. Correction of Class II malocclusion was observed on both Herbst and surgery patients resulting on a normal occlusal relationship with normal overjet and overbite. Therefore it was concluded that Herbst appliance can be used to treat borderline skeletal Class II in adult patients.

The current reports the case of a young patient with malocclusion Class II division 1 on permanent dentition treated in two stages, rthopedics and orthodontics, respectively. At first, the banded Herbst appliance was used duringa 7 months period, followed by a T4K appliance, Trainer for Kids used as retention, and on the second stage the corrective Orthodontics was performed. The results showed the acquirement of a Class I dental relationship, which was kept stable, with excellent intercuspation, even after 5 years of the removal of the Herbst appliance, as well as the correction of the overjet and the reduction of the facial profile convexity. It can be concluded that the Herbst appliance was very efficient in correcting the Class II malocclusion, long term, also providing a very favorable effect on the facial profile.
