ABSTRACT Objective: To assess the impact of the “Dentistry for Infants” early dental care program run by Jacareí County (SP) by comparing the caries of individuals participating and not participating in this program. Methods: In total, 300 children between 0 and 48 months old were assessed in the following two groups: infants not participating in the program (G1, n = 100) and infants participating in the program (G2, n = 200). Each group was further divided according to age in subgroups of 0 to 24 months and 25 to 48 months. All children were clinically assessed for carious lesions using the visual-tactile method. The data were statistically analyzed using a paired Student's t-test, Mann-Whitney test, and χ2 test at a 5% significance level. Results: There was a significant difference in the prevalence (P) and mean index of deciduous teeth (deft) (C) that were decayed, indicated for extraction and filled, and the highest values were observed in G1 (p < 0.0001). The values were as follows: PG1, 73%; PG2, 22%; CG1, 3.45 ± 3.84; and CG2, 0.66 ± 1.57. Conclusion: Participating in the program positively impacted the infants’ oral health.

ABSTRACT Objetive To determine the percentage of correctness of the Orbital Index (OI) for estimation of sex, ancestry and age in Brazilian skulls. Methods Cross-sectional study of 183 human dry skulls from the southeastern Brazil. A total of 100 skeletons were males and 83 females; of which 36 were aged up to 39 years, 60 aged between 40 and 59 years, and 87 aged 60 years or older. As for ancestry, 103 were from white, 51 mixed race, and 29 black individuals. The OI was calculate by the formula = height/width x 100. The data were submitted to Student’s t test, F (ANOVA), Tukey and Kruskal Wallis tests as well as to discriminant analysis, with a 5% significance level. Results The sample was characterized as mesoseme, with a mean age of 56.62 (±19.97) years. No significant difference was observed (p=0.511) between the OI in females (right: 86.43 ± 6.58 and left: 86.70 ± 5.93) and males (right: 85.78 ± 6.69 and left: 86.37 ± 6.20). There were no significant differences between age, ancestry and the variables analyzed (p>0.05). The right and left orbital widths were significantly dimorphic between sexes (p<0.001). The percentage of correctness of the method for estimation of sex, age and ancestry was found to be 65.6%, 43.7%, and 43.6%, respectively. Conclusions The OI is not an appropriate method for estimation of sex, ancestry and estimation of age in this Brazilian sample. The methodology should be expanded to other population groups so that it can be improved.

ABSTRACT Purpose: to investigate forward masking by comparing latencies values of positive and negative peaks in frequency-following responses (FFR) recordings, in normally hearing young adults. Methods: from a database, 20 FFR recordings were selected, 10 being from men, and 10 from women, aged 18 to 25 years, with normal hearing. They were qualitatively analyzed by two experienced researchers and also analyzed, according to two different protocols of recording identification: (i) predominance of positive peaks - PV, A, PW, PX, PY, PZ, and O waves; and (ii) predominance of negative peaks - V, A, C, D, E, F, and O waves. The Shapiro-Wilk normality test, the Wilcoxon test, and the Student’s t-test were conducted, by adopting the significance level of p<0.05. Results: the comparative analysis of latency peak values did not reveal any significant difference between the studied protocols. However, the standard deviation was higher for absolute latency values as compared to negative peaks, suggesting an inverted pattern of what was expected. Conclusion: forward masking was identified in both proposals and the protocol of predominant positive peaks was less variable.

AIM: The aim of this study was to verify two different types of interfaces in Morse taper connection implants, relating the mechanical resistance to a loosening torque that is required to separate or move the prosthetic abutment. MATERIAL AND METHODS: Ten Morse taper connection implants and their respective abutments were divided into two groups (n = 5), DH (double hexagon) interface and OI (octagonal implant) interface. A standard insertion of implants was performed in a stainless steel base, where each abutment received a sequence of two consecutive tightening torques at a 10-minute interval, followed by a loosening torque, which was measured using a digital torque gauge. The Student’s t-test with a 5% significance level was used for data analysis. RESULTS: The results showed a statistically significant difference in the loosening torque values compared with DH torque values (p < 0.05). However, the difference between tightening and loosening torque values was not statistically significant in the OI group (p = 0.465). CONCLUSION: The study concluded that there was a difference in the torque required to loosen the abutment screws between the DH group and the OI group, with the latter showing better results.

Background: Dentists must have accurate knowledge and affirmative attitudes about dental care in order to prevent dental caries. Therefore, the present was conducted with aim to find out knowledge, attitude and actual practices (KAP) for caries prevention in adults on Indian dentist Material and Methods: This cross-sectional questionnaire study was conducted on private dental practitioners of Ghaziabad city. Knowledge on preventive dentistry was assessed by 16 questions with true/false or multiple choice pattern. A total of 8 questions each were utilized for attitude and practices, respectively on a 5-point likert scale. Student’s t-test and One way ANOVA followed by post hoc test was applied to determine the relationship between mean scores of KAP and demographic variables. The significance level was set at below 0.05. Results: Slightly better scores for KAP was found in participants belonging to <30 years of age. The total mean KAP scores of dentists were 8.9 ± 2.2, 26.1 ± 1.7, 21.1 ± 1.9, respectively. Approximately 37% dentist agreed or strongly agreed that fluoride application can prevent dental caries in adults. And 31.5% dentist never advised/performed fluoride application in high caries patients. Conclusion: Strategies to update dentists’ knowledge and practices of primary preventive measures for dental caries may be beneficial in promoting oral health. Findings help in emphasizing the inception and initiation of preventive oral health policies and services in the Indian scenario.

OBJECTIVE: This study evaluated the effect of chemical polishing on the internal adaptation of complete denture bases fabricated with Veracril® resin and polymerized by either the conventional (C) or microwave (M) techniques. MATERIAL AND METHODS: Six groups (n=6/group) were tested: 1) C + no polishing (CO); 2) C + chemical polishing (CQ); 3) C + immersion in hot water at 75ºC (CW); 4) M + no polishing (MO); 5) M + chemical polishing (MQ); and 6) M + immersion in hot water at 75ºC (MW). Internal adaptation immediately after the polishing treatment and after 30 days of storage in water at 37ºC was evaluated by weighing a vinyl polysiloxane film reproducing the gap between resin base and metallic master model, using a precision scale. Data were analyzed by ANOVA and Tukey test and paired Student's t test, at a significance level of 0.05. RESULTS: No significant difference in immediate adaptation was found as a function of technique, polishing treatment, or interaction of technique/polishing. After 30 days, adaptation means (g) were: CO=2.46±0.32 a; CQ=3.40±0.23 d; CW=3.14±0.22 c; MO=3.23±0.37 c, d; MQ=3.41±0.47 d; MW=2.81±0.33 b (means followed by different letters are statistically different at alpha=0.05). All groups but group CO had significant increase of misfit over the tested period. CONCLUSION: The present results suggest that Veracril® resin denture bases submitted to chemical polishing had decrease of internal adaptation in 30 days, although immediate adaptation was not affected.

The aim of this study was to determine the impact of motor abilities on mastering an obstacle course and define quantitative differences in basic motor abilities between the students awarded poor grades and the students awarded higher grades based on the result achieved on the obstacle course designed to test motor skills. The results of regression analysis demonstrated that motor abilities are important for mastering an obstacle course for testing motor skills and, on the basis of them, we may predict the result that defines the students' specific skills. Moreover, the results of the Student's t-test for independent samples demonstrated a statistically significant difference in the level of motor abilities between the students awarded poor grades and those awarded higher grades. The difference is defined by statistically significantly better values of the results achieved on motor tests: the maximum number of sit-ups (MPTP), stick mobility (MOKP), hand tapping (MTAP) and Cooper's 12 minute run test (MKUP), achieved by the students with higher grades, based on which we can assume that these variables are predictive of successful mastery of the obstacle course for testing motor skills. The results obtained might contribute to a better organization of training work in teaching, especially regarding an approach to improving motor abilities that dominantly have an impact on mastering an obstacle course designed to test motor skills.

Aim: Prison is an especially difficult environment for promoting oral health and leads to the exacerbation of unhealthy behaviors. This study set out to assess the impact of incarceration on nutritional status and oral health among the male prison inmates of Central Jail of Jaipur city, Rajasthan, India. Material and method: A cross sectional study was conducted among 181 male inmates. Dental caries and periodontal status were assessed by using modified the Decayed Missing Filled Teeth (DMFT) index and Community Periodontal Index (CPI) and Loss of Attachment (LOA) index as per the WHO methodology 1997. Nutritional status was assessed by Body Mass Index (BMI) and weight (kg)/height (m2). Results: Out of 181 inmates, 141 (77.90%) had normal BMI. The majority (n=128, 70.70%) of inmates were incarcerated for less than 6 years. A significant difference (P<0.05) was found between age and periodontal status. A significant difference was observed (P<0.05) in the CPI score 3 and LOA 0 and 1 score. However, no significant difference (P>0.05) was observed in DMFT and period of incarceration. Age was the significant (P<0.001) risk factor for CPI and LOA. Discussion: Dental caries and periodontal health deteriorates with age and period of incarceration. Oral hygiene maintenance along with comprehensive oral care can be accomplished by establishing dental care facilities in prisons.

ABSTRACT Objective: To test the null hypotheses that children with unilateral agenesis of the mandibular second premolar (MnP2) do not show (1) greater distal angulation of the unerupted antimere and (2) delayed tooth formation compared with children without agenesis. Materials and Methods: Panoramic radiographs of 38 patients with unilateral aplasia of MnP2 were retrospectively examined and compared to a non-agenesic control group of 82 patients. Ages ranged from 8 to 15 years. Contralateral mandibular deciduous second molars were present for all participants. Each unerupted MnP2 was traced, and its developmental stage and angulation were recorded (measured with the distal angle and the premolar-molar angle). Dental age was evaluated using the Haavikko method. Student's t-test was performed to identify significant differences between the compared groups. The significance level for statistical testing was set at P &lt; .05. Results: The results indicated a 9.5° decrease in the distal angle and a 13.2° increase in the premolar-molar angle for the unerupted MnP2 in the agenesis sample. This was a highly statistically significant difference (P &lt; .001 and P &lt; .0001, respectively) compared with the MnP2 inclinations in the control sample. The delay in dental age was significantly greater in patients with agenesis (2.1 years) compared with the delay in the control group (1.5 years) (P &lt; .001). Conclusion: Both null hypotheses are rejected. The results of this study statistically support the hypothesis that aplasia of MnP2, distally displaced MnP2s, and delayed tooth formation are part of a genetically related pattern of dental anomalies.

Background: Although they are not life threatening, dental caries and periodontaldisease are the most predominant and widely spread oral diseases throughout theworld. The aims of the study included the investigation of the prevalence andseverity of dental caries, gingivitis and dental plaque in relation to gender,furthermore, nutritional status was assessed in relation to oral health condition(dental caries).Materials and Methods: This oral health survey was conducted among primaryschool children aged 9 years old in Dewanyiah city in Iraq. The total samplecomposed of 600 child (320 males and 280 females) selected randomly fromdifferent school in Dewanyiah city. Diagnosis of dental caries was according tothe criteria described by WHO (1987). Plaque index of Silness and Loe (1964)was used for plaque assessment, gingival index of Loe and Silness (1963) wasfollowed for recording gingival health condition. Nutritional status was assessedaccording to body mass index (BMI) indicator using anthropometric measurement(height and weight).Results: Results showed that the prevalence of dental caries was 85% for 9 year-oldschool children. Regarding primary and permanent dentition, dental caries washigher among females compared to males with statistically significant difference(P<0.05) for primary dentition, on the other hand, males showed higher values offilled surfaces compared to females with statistically significant difference(P<0.05) for primary dentition and highly significant difference (P<0.01) forpermanent dentition. Finding of this study revealed that 100% of the children hadgingival inflammation. Furthermore, the values of plaque and gingival indiceswere higher among males compared to females with statistically highly significantdifferences (P<0.01). In current study, the prevalence of malnutrition described bythe BMI indicator was 5.3%. For total samples no significant difference wasrecorded in dmfs /DMFS values among wasting and well nourished children(P>0.05).Conclusion: A high prevalence of dental caries and gingivitis were recorded.Improvement in the prevention educational programs is needed among schoolchildren.
