Objective: To assess primary molars early loss in mixed dentition prevalence. Method: A study was carried out in children aged 6 to 12 years. Deciduous molar loss was considered early when it occurred before Nolla stage 6 (full formed crown) of the permanent successor or one year before its physiological exfoliation. Periapical radiographs were obtained to verify the presence of the permanent successor and the level of root formation, as well as the need for placement of fixed space maintainer lingual arch or Nance button. For the study of frequency distribution of early dental loss in relation to gender and dentition, we used the Chi-square test of 5% probability level and the non-parametric Mann-Whitney test for adequate statistical analysis. Results: Of the 315 children examined, 159 (50.47%) were male and 156 (49.52%) were female. Only 25 (7.9%) presented multiple dental losses in the posterior region, 19 in the lower arch and 6 in the upper arch. In the inferior one there was predominance of first and second deciduous molars loss. There was no difference in the association between genders and the occurrence of multiple dental losses (χ² (1) = 0.03, p>0.05). Conclusion: The prevalence of deciduous teeth premature loss was of 7.9% and the most affected teeth were the first and second molars in the lower arch. Lingual arch space holders were installed in 6 children, who will remain with it until the permanent successors erupt into the oral cavity.

Introduction: The period of deciduous teeth is an important period in child development. Damage to deciduous teeth that occur and cannot be treated conservatively will cause premature decay of teeth which is often called premature loss. A space maintainer is a passive tool used to maintain dental arches due to premature loss of deciduous teeth. Method: An 11-year-old girl accompanied by her mother came to RSGMP Unjani in 2018 with complaints of lower right back teeth missing because they have removed. The patient's mother is worried that her replacement teeth will not grow properly. Intraoral examination revealed tooth loss 85. The study model was analyzed using the Moyers method. Results: Analysis of the lower jaw model showed excess space. Patients were treated with a semi-fixed band and loop space maintainer on teeth 85. Conclusion: Premature loss results in excess space in the arch, so as to prevent further occlusion abnormalities in the child's growth and development process, we need a special tool used to maintain space due to premature loss of deciduous teeth.

Objective: This study evaluated the prevalence, clinical management and sequelae in deciduous teeth involved and permanent successors in 150 children (256 deciduous teeth. Of these, 63.3% were male, 24-35 months of age at the time of the trauma (37.9%) and the falls (78.1%) represented the major etiological factor. In relation to the type of injury, 24.6% was enamel fracture; 62.5% showed support tissue injury (lateral luxation, 22.3%). In the first and second assessments (T1 and T2), the average follow-up time was 14.5 and 26 months (256 and 131 teeth).We diagnosed clinical and radiographic sequels including discoloration of the crown (T1-15.6; T2-13.7%), inflammatory root resorption (T1-7.0; T2-8.4%); and in permanent successors, enamel hypoplasia (T1-1.2; T2-2.3%), eruption disturbances (T1-2.0; T2-1.5%).The chi-square test evidenced association, in T1, between injuries to the supporting tissues and clinical (p = 0.003) and radiographic (p = 0.004) sequelae in permanent successors; and between clinical sequelae and age at the time of trauma (p = 0.005). In T2, radiological sequelae in deciduous teeth with injuries to the tooth and supporting tissue (p = 0.035); as well as clinical sequelae with elapsed time of trauma in permanent teeth (p = 0.005). It is concluded that the follow-up of traumatized deciduous teeth is essential to prevent sequelae.

ABSTRACT Objective:  To carry out an immunoassay analysis of biomarkers expressed in gingival crevicular fluid (GCF) with the main goal of finding a useful diagnostic pattern to distinguish between resorbing deciduous teeth and nonresorbing controls. Materials and Methods:  A split-mouth design was used in this study with a total of 22 GCF samples collected from 11 patients in the mixed dentition. For each child, one deciduous molar with radiographic evidence of root resorption was used as the test tooth whereas the contralateral first permanent molar with formed roots was used as the control tooth. Samples were processed with immunoassays using a panel of selected biomarkers including interleukin-1 beta (IL-1b), interleukin-1 receptor antagonist (IL-1RA), nuclear factor kappa B ligand (RANKL), osteoprotegerin (OPG), matrix metalloproteinase-9 (MMP-9), and dentin sialoprotein (DSP). Results:  There were no statistically significant differences in levels of IL-1b, OPG, and MMP-9 between test and control sites (P > .05). IL-1RA was the only biomarker to show a significant down-regulation (P  =  .04) in GCF samples collected from resorbing teeth. RANKL data showed a heavily skewed distribution and was deemed unreliable. Only one deciduous GCF sample had detectable levels of DSP; therefore, no further statistical calculation was applicable because of the limited amount of data for this biomarker. Conclusions:  This study indicated that IL1-RA is down-regulated in GCF from resorbing primary molars, thus suggesting this cytokine as a potential analyte to be included in a panel that can discriminate between resorbing and nonresorbing teeth.

Exfoliation rates of deciduous molars and canines of 705 children were determined. Exfoliation of the mandibular canines begins at about the age of seven years, and is followed by exfoliattion of the first and second molars. Maxillary exfoliation begins with the canines and first molars, followed by the second molars. Deciduous canines and molars often are present at the age of ten years.

Introduction: The present study sought to assess the effect of apical foramen cleaning in the repair of periapical lesions detected by radiography. Methods: The sample comprised 980 teeth collected from 25 February 1997 to 15 March 2005 which had been subjected to endodontic treatment and exhibited radiographically visible periapical lesions. The sample was then divided into two groups: Group I, 402 root canal treatments in which cleaning of the apical foramen had not been performed, and Group II, composed of the remaining 578 root canal treatments where the procedure had been performed. After one year, the teeth were clinically and radiographically evaluated. Results: In Group I, 360 canals (89.55%) had no evidence of periapical lesions, versus 521 (90.13%) in Group II. Partial presence of these lesions was observed in 23 canals (5.72%) in Group I versus 27 (4.67%) in Group II. No changes in images were observed in 19 (4.72%) canals in Group I and 30 in Group II. Pearson’s chi-square test showed no statistically significant difference between the Groups I and II (p = 0.732). Conclusions: These findings suggest that foramen cleaning is not a determinant of periapical lesion repair.

Cleft lip and palate (CLP) is the most frequent congenital malformation among the anomalies of the head and neck. The orthopedic/orthodontic treatment is included in the rehabilitation of these individuals, however there is no consensus in the literature regarding the ideal time for its beginning. Objective: To verify and characterize the profile of individuals with CLP treated at a reference hospital of the northeast of Brazil from 1998 to 2013 and its association with the beginning of the orthopedic/ orthodontic treatment. Material and methods: Through direct observation of medical records, panoramic radiograph, and study casts of 323 individuals, data regarding sex, cleft type, origin and age of beginning of the orthopedic/orthodontic treatment were surveyed and analyzed using the chi-square test, considering a 5% level of significance. Results: Most of the individuals had transforamen and the unilateral cleft was the most prevalent (p<0.05). Females were statistically more affected by post-foramen cleft and males by trans-foramen cleft (p><0.05). Most individuals with trans-foramen cleft and post-foramen cleft started the orthopedic/ orthodontic treatment between 8 and 12 years old (p><0.05). No statistically significant differences occurred relating the beginning><0.05). Females were statistically more affected by post-foramen cleft and males by trans-foramen cleft (p<0.05). Most individuals with trans-foramen cleft and post-foramen cleft started the orthopedic/ orthodontic treatment between 8 and 12 years old (p<0.05). No statistically significant differences occurred relating the beginning> <0.05). No statistically significant differences occurred relating the beginning of the orthopedic/orthodontic treatment with geographic origin and sex of, although most of them have started treatment at late mixed dentition. Conclusion: Regardless of gender, origin, or cleft type, most patients started orthopedic treatment up to 12 years-old, an age considered ideal by most protocols. Unilateral and trans-foramen cleft were the most prevalent cleft types. post-foramen cleft affected more females, while trans-foramen cleft affected more males.

Background: There was a strong correlation between increase in hypertension and changing lifestyle factors. The problem which lies with the hypertension is that it cannot be cured completely. And its management requires lifelong medication with some life-style modifications. Decreased physical activities coupled with increased mental tension are important contributors of hypertension. They are usually seen amongst employees of the profession where working is typically sedentary.  The main objectives were to study on prevalence of hypertension and risk factors among Government Gazetted officers of Maharashtra, India.Methods: A cross sectional study was carried among gazetted officers working in various departments of state Government for a period of one year in Solapur district. 355 Gazetted Government officers of class I & class II cadre were studied. Blood pressure was measured with a standard mercury sphygmomanometer. Chi-square test was applied to assess risk factors.Results: In present study, the prevalence of hypertension among Gazetted officers was observed 20.28%. There was significant positive association was found between age and prevalence of hypertension. And also it was found significantly higher in men than women. The association between education and hypertension found to be statistically significant (P<0.001), while there was no association between socioeconomic status and hypertension was found (P=0.33). Prevalence of hypertension was noted higher at every level of BMI. Prevalence of hypertension was significantly higher in smokers, alcoholic and had significant association (P<0.05).Conclusions: We conclude that, because of high prevalence of hypertension in Gazetted officers, periodically they should be screened for the same.

Objective Type and prevalence rates of the symptoms of Hoffmeister's “genetically determined predisposition to disturbed development of the dentition” were studied in patients with clefts. Patients Data of 263 patients with nonsyndromic clefts of lip (alveolus and palate) or isolated cleft palates were examined in a retrospective study. Setting The clefts were classified as cleft lip or cleft lip and alveolus, cleft palate, unilateral cleft lip and palate, and bilateral cleft lip and palate. All patients were scrutinized for 28 individual symptoms. Prevalences of the individual symptoms were statistically evaluated regarding cleft type and gender by using the chi-square test and were also compared with findings in patients without clefts. Results In 97.7% of the patients with clefts, at least one symptom was found. Microdontia of individual teeth, hypodontia, and hyperodontia were the symptoms most frequently recorded. Comparison of the different cleft types revealed differences regarding the prevalences of supernumerary lateral incisors (p = .051), infraposition of deciduous molars (p < .001), and atypical tooth bud position (p = .030). Comparison of the prevalences of 10 symptoms recorded in the patients with clefts with the prevalences recorded in patients without clefts showed nine symptoms were found much more frequently in the population with clefts. Conclusion These findings support the hypothesis that clefting is part of a complex malformation associated with other dental anomalies resulting from disturbed development of the dentition. Patients with clefts are also likely to present other deficiencies of dental development and tooth eruption in both dentitions, even in regions not affected by the cleft.

Toxoplasma Gondii Infection

Blood samples were collected from 89 cats to assess the prevalence of IgG antibodies against Toxoplasma gondii by indirect immunofluorescence (IIF) and the possible risk factors associated with feline Toxoplasma gondii infection. An epidemiological questionnaire was developed and implemented for owners of domestic cats domiciled in Rio Branco, Acre. The results were statistically evaluated with the odds ratio and chi-square tests, considering the significance level of 5%. Of 89 animals’ samples, 22 had antibodies against Toxoplasma gondii. Among the 22 reactive animals, 15 (68.19%) were female, 15 (68.19%) were less than one year old and 20 (90%) were cross breed. Concerning risk factors, there was no difference (p > 0.05) between the variables evaluated by the chi-square test. Moreover, 16 (72%) cats were fed a mixed diet, 20 (90%) of the cats had hunting habits, 18 (81%) had contact with animals of another species, 11 (50%) had access to the street, and 22 (95%) lived in homes that had areas of grass or dirt. In conclusion, the prevalence of anti-Toxoplasma gondii in domestic cats was 22.7%, and there were no significant risk factors for feline toxoplasmosis in the municipality of Rio Branco, Acre.
