Twenty-year clinical experience with fixed functional appliances.

Abstract: Introduction: Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task. Objective: To describe the development of fixed functional appliances as well as our 20-year experience working with them. Methods: Fixed functional appliances are grouped into flexible, rigid and hybrid. They are different appliances, whose action is described here. Four clinical cases will be reported with a view to illustrating the different appliances. Conclusions: Rigid fixed functional appliances provide better skeletal results than flexible and hybrid ones. Flexible and hybrid appliances have similar effects to those produced by Class II elastics. They ultimately correct Class II with dentoalveolar changes. From a biomechanical standpoint, fixed functional appliances are more recommended to treat Class II in dolichofacial patients, in comparison to Class II elastics.

Relationship between orofacial pain and absenteeism among workers in Southern Brazil

Abstract: Aim: To verify the relationship between orofacial pain and absenteeism in workers of slaughter and meat processing industries in the Southern region of Brazil. Methods: A cross-sectional study, with the random sample of 401 workers of slaughter and meat processing industries in the Southern region of Brazil, was carried out. A questionnaire referred to the situation of absenteeism caused by nine different types of orofacial pain and also the amount of time the employee was kept from work. Results: Only 60 workers (15%) reported having missed work due to orofacial pain in the six months prior to the study. The prevalence of absenteeism resulting from orofacial pain was of 15%. The types of orofacial pain that resulted in absenteeism were: spontaneous toothache (9.7 %); toothache caused by cold or hot liquids or by sweet foodstuff (6.5%) and pain around and behind the eyes (3.2%). There was a predominance of absenteeism in half and full work shifts for the types of orofacial pain experienced. Associations between absenteeism from induced toothache and gender (p < 0.05), absenteeism and spontaneous toothache and family income (p = 0.011), and between absenteeism and the self awareness of their oral health condition, as well as the nine types of orofacial pain (p < 0.001) were observed. Conclusions: The prevalence of absenteeism as a result of orofacial pain was low.

Marginal and Internal Adaptation of Zirconia Crowns: A Comparative Study of Assessment Methods.

Abstract: Marginal and internal adaptation is critical for the success of indirect restorations. New imaging systems make it possible to evaluate these parameters with precision and non-destructively. This study evaluated the marginal and internal adaptation of zirconia copings fabricated with two different systems using both silicone replica and microcomputed tomography (micro-CT) assessment methods. A metal master model, representing a preparation for an all-ceramic full crown, was digitally scanned and polycrystalline zirconia copings were fabricated with either Ceramill Zi (Amann-Girrbach) or inCoris Zi (Dentslpy-Sirona), n=10. For each coping, marginal and internal gaps were evaluated by silicone replica and micro-CT assessment methods. Four assessment points of each replica cross-section and micro-CT image were evaluated using imaging software: marginal gap (MG), axial wall (AW), axio-occlusal angle (AO) and mid-occlusal wall (MO). Data were statistically analyzed by factorial ANOVA and Tukey test (a=0.05). There was no statistically significant difference between the methods for MG and AW. For AO, there were significant differences between methods for Amann copings, while for Dentsply-Sirona copings similar values were observed. For MO, both methods presented statistically significant differences. A positive correlation was observed determined by the two assessment methods for MG values. In conclusion, the assessment method influenced the evaluation of marginal and internal adaptation of zirconia copings. Micro-CT showed lower marginal and internal gap values when compared to the silicone replica technique, although the difference was not always statistically significant. Marginal gap and axial wall assessment points showed the lower gap values, regardless of ceramic system and assessment method used.

Aplicação foliar de extrato de alga, ácido l-glutâmico e cálcio em feijoeiro

Abstract: This work had as aim to evaluate the effects of foliar application of Ascophyllum nodosum extract, L-glutamic acid and Ca +2 , alone or in mixed solutions, over growth and grain production of common bean ( Phaseolus vulgaris L.). The research was carried out in greenhouse with the following treatments: without application; solution with 60 g L -1 L-glutamic acid; solution with 60 g L -1 extract; solution of CaCl 2 with 100 g L -1 de Ca +2 ; mixed solution with 30 g L -1 L-glutamic acid, and 30 g L -1 extract; mixed solution with 30 g L -1 L-glutamic acid and 100 g L -1 Ca +2 in CaCl 2 form; mixed solution with 30 g L -1 extract and 100 g L -1 Ca +2 ; mixed solution with 15 g L -1 L-glutamic acid, and 15 g L -1 extract, and 100 g L -1 Ca +2 . The solutions were diluted in water at 3 ml L -1 concentration, and have been sprayed over the plants, on 12, 28 and 42 days after the emergence. Biometrical parameters were evaluated during plants growth, and at the end, the grain production was quantified. Data analysis has shown the effect of solutions in plants growth and grain production, characterizing the biostimulant effect of the mixed solution with 30 g L -1 extract and 100 g L -1 Ca +2 , and the mixed solution with 15 g L -1 L-glutamic acid, and 15 g L -1 extract, and 100 g L -1 Ca +2 .
