ABSTRACT Objective to analyze the predictive factors for the aggravation of chronic wounds. Methods quantitative, cross-sectional study, whose collection was performed using the Bates-Jensen Wound Assessment Tool. For data analysis, the independent t test, analysis of variance and multiple linear regressions were applied. The level of significance adopted was 0.05. Results in the bivariate analysis, it was observed that the variables making use of tobacco (p=0.005), presenting food restriction (p=0.001), signs of infection (p=0.005), odor characteristics (p<0.001) and evaluation pain (p=0.012) contributed to the worsening of chronic wounds. Conclusion it was found as predictors for the worsening of wounds: using tobacco, having food restriction of the hypo sodium or hypoglycemic type, in addition to presenting edema in the surrounding area, as a sign of infection.

RESUMO Objetivo analisar os fatores preditores ao agravamento de feridas crônicas. Metódos estudo quantitativo, transversal, cuja coleta foi realizada por meio do instrumento Bates-Jensen Wound Assessment Tool. Para análise dos dados, aplicaram-se o teste t independente, a análise de variância e a regressão linear múltipla. O nível de significância adotado foi 0,05. Resultados na análise bivariada, observou-se que as variáveis fazer uso de tabaco (p=0,005), apresentar restrição alimentar (p=0,001), sinais de infecção (p=0,005), características do odor (p<0,001) e avaliação da dor (p=0,012) contribuíram para o agravamento das feridas crônicas. Conclusão constatou-se como preditores para o agravamento de feridas: fazer uso de tabaco, possuir restrição alimentar do tipo hipossódica ou hipoglicemiante, além de apresentar edema na área perilesional, como sinal de infecção.

Abstract Objectives: To evaluate the effect of calcium hydroxide (CH) associated with two different vehicles as a capping material for pulp tissue in primary molars, compared with mineral trioxide aggregate (MTA). Methodology: Forty-five primary mandibular molars with dental caries were treated by conventional pulpotomy using one of the following materials: MTA only (MTA group), CH with saline (CH+saline group) and CH with polyethylene glycol (CH+PEG group) (15 teeth/group). Clinical and periapical radiographic examinations of the pulpotomized teeth were performed 3, 6, and 12 months after treatment. Data were tested by chi-squared analysis and a multiple comparison post-test. Results: The MTA group showed both clinical and radiographic treatment success in 14/14 teeth (100%), at all follow-up appointments. By clinical evaluation, no teeth in the CH+saline and CH+PEG groups had signs of mobility, fistula, swelling or inflammation of the surrounding gingival tissue. However, in the CH+saline group, radiographic analysis detected internal resorption in up to 9/15 teeth (67%), and inter-radicular bone resorption and furcation radiolucency in up to 5/15 teeth (36%), from 3 to 12 months of follow-up. In the CH+PEG group, 2/11 teeth (18%) had internal resorption and 1/11 teeth (9%) presented bone resorption and furcation radiolucency at all follow-up appointments. Conclusion: CH with PEG performed better than CH with saline as capping material for pulpotomy of primary teeth. However, both combinations yielded clinical and radiographic results inferior to those of MTA alone.

This paper reports a series of clinical cases of ankyloglossia in children, which were approached by different techniques: frenotomy and frenectomy with the use of one hemostat, two hemostats, a groove director or laser. Information on the indications, contraindications, advantages and disadvantages of the techniques was also presented. Children diagnosed with ankyloglossia were subjected to different surgical procedures. The choice of the techniques was based on the age of the patient, length of the frenulum and availability of the instruments and equipment. All the techniques presented are successful for the treatment of ankyloglossia and require a skilled professional. Laser may be considered a simple and safe alternative for children while reducing the amount of local anesthetics needed, the bleeding and the chances of infection, swelling and discomfort.
