title: Variation of digital palpation pressure used in the clinical examination of TMJ disorders and orofacial pain

description: OBJECTIVE: The present research aims to evaluate the calibration of digital palpation pressure as well as to assess the inter-examiner variation and mean pressure used by a sample consisting of 56 professionals of the TMJ disorders and Orofacial Pain area. METHODS: Each participant was asked to press a digital balance to approach 1.0 kg and subsequently 0.5 kg without seeing the display, in order to obtain a blind data. The values of 1.0 kg and 0.5 kg are recommended by the Research Diagnostic Criteria for Temporomandibular Disorder in the refined Axis I, the Physical Assessment. Participants were considered calibrated when they applied the correct pressure in at least 4 of the 5 measurement taken; within a 20% variation interval (pressures between 0.4 and 0.6 kg were acceptable for the reference value of 0.5 kg and between 0.8 and 1.2 kg for the reference value of 1.0kg). The t-student test was used to analyze data (p≤0.05). RESULTS: 70% of the sample was classified as non- calibrated for the 0.5 kg pressure while 57% were not calibrated for the 1.0 kg pressure. The mean inter-examiner variations, 0.3 kg for the pressure set at 0.5kg and 0.6 kg for the pressure set at 1.0 kg, were considered high. CONCLUSION: The mean pressures applied by participants (0.7 kg for joint palpation and 1.4 kg for muscle palpation) were also considered high in comparison with those recommended by the Research Diagnostic Criteria for Temporomandibular Disorder, but acceptable according to the tendency of applying higher values of 1.0 - 1.5 kg, as proven by recent study.

title: Profile of dentists in oral health team of a microregion of Minas Gerais, Brazil

description: OBJECTIVE: To describe the profile of dentists in oral health team of the micro-region of Minas Gerais, Brazil. METHODS: Cross-sectional study with 48 dentists in 16 municipalities, in which data collection was conducted by questionnaire. The variables considered for the study were: training time in years, and monthly real salary (centroid), in compliance with weekly working hours, mode of incorporation into the oral health team, postgraduate course, social participation and ongoing involvement in Family Health. All variables were used to group dentists by Two Step Cluster analysis segmentation, with p &lt;0.05 significance level. RESULTS: They formed three clusters that differed mainly in relation to training time in years (p = 0.007), hours worked (p &lt;0.001), postgraduate course (p &lt;0.001) and social participation (p = 0.031). The first cluster grouped dentists with less training time, receiving an intermediate salary to comply with the stated working hours and lack of post-graduate course, the second grouped dentists with the highest salaries and years of graduation who have post-graduate course and the last was composed of dentists with intermediary training time, the lowest salaries that complied with the working hours, have attended the training course / training in the Family Health Strategy and have no social participation. CONCLUSION: Dentists in the Family Health Strategy differ as regards weekly working hours, postgraduate course and social participation in the city, and the training time can be a critical feature to point out these differences.

title: Prevalence and severity of orofacial pain in pregnant women

description: OBJECTIVE: To evaluate the prevalence and severity of oral pain in pregnant women. METHODS: A cross-sectional study was conducted on a sample of pregnant women who were receiving dental care at a Dental School. A structured questionnaire about self-perception of oral conditions and the presence and severity of orofacial pain in the mouth or teeth in the last 6 months was applied. RESULTS: 80 pregnant women participated in the study and, of these, 58.8% reported having a problem with their teeth, 31.3% periodontal problems, 61.3% bad taste in mouth and 62.5% bad breath. Only 22.5% of pregnant women did not exhibit any form of oral pain. The most frequently reported pains were: pain with hot/cold liquids or sweets (56.2%) and spontaneous toothache (38.8%). With regard to severity, mild and moderate pain were the most frequently reported, but there was a group of 23.8% of pregnant women with severe or very severe pain caused by hot or cold liquids and 18.8% in the same condition in relation to spontaneous pain. CONCLUSION: The results of this study showed that, despite the high prevalence of pain detected in the pregnant women, severity was low and referred to specific situations.

title: Evaluation of the pH and titratable acidity of teas commercially available in Brazilian market

description: OBJECTIVE: Tea has been considered a healthy alternative to other industrialized beverages. The objective of this study was to assess the erosive potential of teas commercially available in Brazil by pH and titratable acidity measures. METHODS: Eighteen teas available in Brazilian market were selected for this study (read to drink and brewed tea), and a brand of yerba mate (Ilex paraguariensis). Each product was analyzed for pH and titratable acidity. For comparison between different kinds of teas, the Student t test was used. RESULTS: The mean pH values for ready to drink teas ranged between 2.89 and 4.03, while for the brewed teas and yerba mate the values ranged between 6.75 and 7.89. The difference between the two groups was significant (p &lt; 0.05). Regarding titratable acidity, the ready to drink teas showed mean values ranging between 3.77 ml and 12.68 ml. Brewed teas (including yerba mate) were not tested for titratable acidity because their pH values were greater than 7.0. CONCLUSION: Among the teas commercially available, ready to drink teas have lower pH values and higher titratable acidity compared to other teas. It suggests that they have an erosive potential.

title: Effect of 17% EDTA on removal of canal wall smear layer and calcium hydroxide dressing: part II

description: OBJECTIVE: the aim of this study was to evaluate, by scanning electron microscopy, the effectiveness of 17% EDTA on removal of canal wall smear layer and calcium hydroxide dressing in different thirds of root canal. METHODS: Ttwenty-four premolars were instrumented in the cervical and middle thirds using Gates-Glidden drills. At the working length, the canal was widened up to # 35 file, followed by scaling up to file # 50. After instrumentation, the teeth were divided into four groups according to the treatment received: GI - irrigation performed with 5 ml of NaOCl 2.5 % ; GII - irrigation with 5 ml of 17% EDTA for 2 and a half minutes , submitted to agitation with file # 15, followed by irrigation with 5 ml of 2.5% NaOCl ; GIII - irrigation with 5 ml of NaOCl 2.5% , drying , application of temporary dressing of Ca (OH )2 with propylene glycol and sealing. After 5 days , removing the sealing irrigation with 5 ml of 17% EDTA for 2 and a half minutes , submitted to agitation with file # 15, followed by a final flush with 5 ml of 2.5% NaOCl ; GIV - irrigation with 5 ml of 17% EDTA for 2 and a half minutes , submitted to agitation with file # 15 , followed by irrigation with 5 ml of 2.5% NaOCl , drying and after use of the medication in Ca (OH )2 with the sealing and propylene glycol which was removed after 5 days performing the irrigation with 5 ml of 17% EDTA for 2 and a half minutes , submitted to agitation with file # 15, followed by using 5 ml 2.5% NaOCl . Next, the teeth were prepared and taken to the scanning electron microscope . RESULTS: The images revealed: Group I - a marked presence of smear layer in all three thirds, Group II - removal of almost all of the smear layer in the cervical third and removal of large quantity in the middle third, whereas in the apical third a large quantity of smear layer still remained however, in comparison with the other groups, this was shown to be cleaner; Group III - in the three thirds, the presence of smear layer was observed, which was shown to be much less compacted than that observed in Group 1; Group IV- in all the thirds there was reduction of smear layer and Ca(OH)2-based medication, and presence of several unobstructed dentinal tubules could be observed, demonstrating the second best result observed. CONCLUSION: It could be concluded that the use of 17% EDTA favored removal of the smear layer and intracanal medication residues in all thirds of the root canal.

title: Relative area measurement of maxillary sinus by computed tomography

description: OBJECTIVE: To evaluate the relative area of the maxillary sinus in edentulous posterior maxilla with regard to linear area, bone septa and sinus pathologies. METHODS: A retrospective longitudinal study was conducted of tomographic exams in 60 individuals between 35 and 75 years of age, with the inclusion criteria being the uni- or bilateral edentulous posterior maxilla. Measurements were taken by the program in 101 maxillary sinuses. The horizontal and vertical measurements of each sinus were multiplied and resulted in a linear area in mm2. RESULTS: Of the 101 maxillary sinuses evaluated, 14 presented sinus pathologies (13.86%) and 22 (21.78%) with bone septa. The mean mesio distal distance was 38.4 mm (p ≤ 0.05), mean height 34. 5 mm (p ≤ 0.05) and mean linear area of 1335.88 mm² (p = 0.05). The Student's-t and analysis of variance (ANOVA) tests were applied for statistical analysis There were no statistically significant difference in the height and width of the edentulous maxillary sinuses between genders, but there was a variation in the linear area and the finding of the presence of bone septa and sinus pathologies. CONCLUSION: The conclusion of this study corroborates those of previous study about the need for imaging exams with the purpose of obtaining information about the dimensions of the maxillary sinus, as guidance with regard to the quantity of graft material, choice of donor region, and presence of septa. These data serve as guidance in the sinus lift technique and the presence of sinus pathologies, which involve treatment before bone graft surgeries.

title: Indirect pulp treatment without re-entry in a permanent tooth: 36 months of follow-up

description: An alternative approach in the management of deep caries lesions is the indirect pulp treatment, without re-entry in the cavity. It has been shown that the complete removal of the carious dentin became unnecessary after the total tooth sealing, because the remaining microorganisms of the affected dentin would stop proliferating and/or die. This case report describes the management of a deep caries lesion of an 11-year-old girl with great coronary destruction in the left mandibular permanent first molar. Infected dentinal walls were excavated with manual instruments and the remainder affected dentin was filled with ionomer glass cement and composite resin. After 36 months of follow-up, no clinical and radiographic signs and symptoms of pulp damage were observed. In conclusion, the indirect pulp treatment was considered a good alternative for the treatment of deep caries lesions as it reduced the risk of pulp exposure by not reopening the cavity, saved the patient and the dentist clinical time and arrested the lesion progression with radiographic density increase and absence of any pain symptoms.
