The aim of the present study was to determine the existence of inter dental papilla according to the vertical dimension, horizontal dimension and the combined effects of the vertical and horizontal dimensions of the interproximal space on the existence of interdental papilla.182 interdental sites of 42 periodontitis patients undergoing open flap debridement were included in the study. The existence of interdental papilla was determined based on the Papilla Presence Index (PPI). The vertical dimension (VD) was measured from the alveolar crest to the contact point using UNC-15 probe. Horizontal dimension (HD) was measured from the mesial surface of the distal tooth and the distal surface of the mesial tooth at the level of the alveolar crest using castroviejocaliper. Statistical analysis was done by using independent ‘t’ test, Pearson’s Chi-square test and Trend Chi-square test. The existence of papilla was significantly higher in VD ≤ 5mm (91.5%) compared to VD > 5mm (9.8%) [p< 0.0001]. The existence of papilla was significantly higher in HD < 2mm (97%) compared to HD ≥ 2mm (1.2%) [p< 0.0001]. The contribution of both vertical dimension and horizontal dimension to the existence of papilla was about 61.6% and thus the existence of papilla may be influenced by various other factors (about 38.4%) which were not included in this study.The vertical and horizontal dimensions of the interproximal space gains significance in determining the existence of papilla and further research is needed to analyze the other factors influencing the papilla.

AbstractObjective: The purpose of the present study is to evaluate the disintegration of the contact point system, the occlusal changes, and the masticatory force following the loss of the first permanent molars (FPM).Material and methods: Clinical examinations were performed among 8-18-year-olds following the changes in the contact points and their effects on the dento-maxillary apparatus. The sample comprises 422 individuals, 220 girls and 202 boys. The occlusal masticatory force was measured using the T-Scan in the case of the opening of contact points. For the statistical data analysis, was used correlation and Chi Square Test in the GraphPad InStat program.Results: A very weak reverse dependence was found between the size of the edentulous space and the deflection of the upper and lower interincisal lines (r=-0.02) and between the age and size of the edentulous space (r=-0.05). There is a statistically significant chance of mandibular lateral deviation by dental migration following edentulism (p=0.043). In the case of the opening of contact points, there are 1.42 times higher risks of modified sagital relationship in the molar segment (p=0.016) and 2.7 times greater risks of the tipping of the neighbouring teeth (p=0.021). Following the evaluation of the T-Scan measurements, we found in each case a significant decrease in the masticatory force in the edentulous area and the opening of the interproximal contact points.Conclusion: Based on the obtained results, we can state that the opening of contact points decisively influences the stability of the occlusion and the size of the masticatory force.

Introduction During the practical classes of Dental Anatomy, some students have difficulties in identifying the mandibular first premolars, especially in determining the proximal surfaces. Objective The objective of this study was to evaluate the anatomical structures of those teeth, to determine the criteria for identifying the proximal surfaces in individual teeth. Materials and Methods Two hundred mandibular first premolars belonging to 100 individuals, at the age of 18 to 25 years old and from both sexes were evaluated according to some features of the dental crown. The associations of interest were estimated using the chi-square test or Fisher's Exact Test and kappa statistic. The level of significance was 5%. Results The distal occlusal fossa (DOF) was the widest fossa (94.5%), and the distal surface constituted the proximal surface with the largest dimension (94.5%). It was found that in 60% of the teeth, the DOF was located closer to the lingual surface. The grooves from the mesial and distal occlusal fossa, toward the lingual surface, were absent in most teeth (64.5% and 91.5%, respectively). Conclusions The criteria for determining the proximal surfaces when evaluating individual first mandibular premolars should be: DOF will be the widest occlusal fossa; the proximal surface with the largest buccolingual dimension will be the distal surface. The occlusal fossa which is closer to the lingual surface may also be evaluated, being considered as the DOF. However, this should be considered the last of the three highlighted criteria, since it generates a greater margin of error in relation to the others.

Full mouth rehabilitation is a comprehensive treatment and hence requires a longer duration along with patient co-operation and operator skill. Data of 86000 patients between June 2019 and March 2020 was reviewed from the patient's records and analysed that was documented in Saveetha Dental College and Hospital, Chennai, India. 152 patients who underwent tooth supported full mouth rehabilitation were included in this retrospective study. The data regarding the duration of the entire treatment, patient satisfaction, type of temporary teeth and change in vertical dimension was collected from Dental Information Archiving Software (DIAS). The data censored was collected by recalling the patient and reviewing. Statistical analysis was performed using pearson's correlation and chi square test to assess the association between patient satisfaction and increase in the vertical dimension, type of temporisation and duration of the treatment. The associations between patient satisfaction and increase in vertical dimension (Chi-square value : 8.809, df: 6, p value : 0.185), type of temporisation (Chi-square value : 8.809, df: 6, p value : 0.185) and duration of the treatment (Chi-square value : 303.548, df: 306, p value : 0.529) were statistically insignificant (p>0.05). From the available data it was observed the duration of the treatment plays a secondary role in relation to patient satisfaction in the treatment of full mouth rehabilitation cases. The quality of treatment and decisiveness in providing definitive care with respect to treatment needs gives better patient satisfaction.

The Moment

Breast feeding is giving milk to be drunk to the baby from the breast. Uterus involution is a process how the uterus return to the condition back, before pregnanting after bearing. At the moment of suckling, happens a stimulus and brings the hormones out, such as oksitosin uses not only to stimulate some muscles constraction but also to stimulate the uterus, so that the process of uterus involution happens foster. According to the explanations above, the research aimed to know about the correlation between breast feeding and uterus involution. This research’s design was, cross sectional by the population of all childbirth mothers approximately 50 persons / month. By using accidental sampling technique we got 21 sample respondents. The place of research in RSIA Aura Syifa in Kediri Regency on 16th until 22nd of June 2009. From this research’s result, we got 14 persons (66,67%) with normal uterus involution, suckled in a good way, one person (4,67%) with normal uterus involution, suckled in a wrong way, 2 persons (9,52%) with abnormal uterus involution, suckled in a good way and 4 persons (19,05%) with abnormal uterus involution, suckled in a wrong way. Statistic test which used chi-square test, counted the probability frequency in advance, from that we got 3 columns with the score, less than 5, so that chi-square can not be continued and by doing exact fisher test, the score was 0,001. Because P with the grade mistake 0,05 smaller, so the conclusion was “Ho” is rejected, it meant “there was correlation between suckling and uterus involution”. Key Word : Breast feeding, uterus involution

ABSTRACT : The House index and Container Index in the buffer area of ​​the working area of ​​Balikpapan Sepinggan Airport is still above 1%, so the potential for the spread of dengue disease. Mobilization of people, goods and transportation equipment will increasingly affect the transmission of disease in ports and airports, especially for vector-borne diseases. This study aims to analyze the risk factors associated with larvae density of Aedes aegypti and describe the larvae index in the buffer zone of the Sepinggan Balikpapan Airport This study was a descriptive study with a cross sectional design. The sample in this study was 121 houses with a proportionate stratified random sampling, the research location was in the buffer zone of Sepinggan Balikpapan Airport in November 2018. The variables studied were houses with positive larvae containers, breeding sites and PSN behavior and larvasidation. The data was analyzed using the chi square test. There was a relationship between houses with larvae positive Aedes aegypti, behavior of Mosquito Nest Eradication (PSN) and larvasidation with larvae density of Aedes aegypti but not for breeding sites (p = 0.00 and 95% CI = 0.64), and   (p = 0.00 and 95% CI = 0.34). The description of several Aedes aegypti larvae index, namely House Index (HI) = 57.02%, Container Index (CI) = 24.36%, Bruteau Index (BI) = 148.76, and Flick Free Numbers (ABJ) = 42.98 %. Houses with larvae of Aedes aegypti larvae and PSN and larvasidation behavior were associated with larvae density of Aedes aegypti. The index of HI, CI and BI larvae is of high value so there is a risk of DBD transmission

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender
