Abstract

The purpose of this investigation is to compare the response of primary teeth clinically and histopathologically to vital pulp therapy using formocresol (FC), Ferric sulfate (FS), and Pulpotec (PD). A total of 60 primary molars were treated in 43 children aged 7-9 years. Twenty primary molars received FC, and an equal number received FS, and PD by random selection. Clinical evaluations were performed at 3 and 6 months recall for the whole samples. Histopathological evaluations were carried at 6 months for the teeth indicated for extraction (total 30) as part of the orthodontic treatment. Statistical analysis using Z-test was performed on the data to determine significant differences between the groups. Three and six months results showed a highly significant difference (P< 0.01) between the tested materials in most clinical findings, while histopathologically after 6-months in the FC group mild inflammation was seen in two cases, severe inflammation in three cases, necrosis in two, and abscess in one case. In the FS group mild in one case, severe in three cases, necrosis in one case, and abscess in two cases, finally in PD group mild inflammation was seen in one case, severe in one case, necrosis in one case, with no abscess formation in any case. Clinical and histopathological evaluations showed that Pulpotec (PD) can be considered as a replacement for FC and FS.

إنّ الهدف من هذا البحث هو مقارنة استجابة الأسنان اللبنية سريرياً ونسيج مرضياً لعملية تحنيط لب السن الحي واستعمال مادة الفورموكريزول ,مادة الفريك سلفيت,ومادة البلبوتيك. شملت الدراسة للأسنان 60 طاحن لبني من مجموع 43 طفل تتراوح أعمارهم بين 7-9 سنوات. قسمت الاسنان الى ثلاثة مجموعات, المجموعة الاولى تضمنت 20 طاحن لبني عولج بمادة الفورموكريزول, والمجموعة الثانية 20 طاحن لبني عولج بمادة الفريك سلفيت, والمجموعة الثالثة 20 طاحن لبني عولج بمادة البلبوتيك تم اختيارالمجاميع عشوائياً.جميع الحالات قيمت سريرياً بعد 3 و 6 أشهر متابعة,أمّا التقييم النسيج مرضي فقد تم بعد 6 أشهر للأسنان التي تحتاج إلى قلع كجزء من المعالجة التقويمية.أظهرت النتائج السريرية عند 3و6 أشهر متابعة فروق معنوية كبيرة بين المواد المختبرة, أما النتائج النسيجية بعد 6 أشهر فقد أظهرت:-حالتي التهاب طفيف, 3 حالات التهاب شديد, حالتين موت اللب, وحالة واحدة خراج من مجموع 10 حالات لمجموعة الفورموكريزول. أمّا مجموعة الفريك سلفيت فكانت حالة واحدة أظهرت التهاب طفيف , 3حالت التهاب شديد, حالة واحدة موت اللب, وحالتين خراج من مجموع 10 حالات أيضاً, و أخيراً مجموعة البلبوتيك فكانت حالة واحدة التهاب طفيف, حالة واحدة التهاب شديد, حالة واحدة موت اللب ولم تظهر أي حالة خراج. أظهرت النتائج السريرية والنسيج مرضية أنّ مادة البلبوتيك يمكن اعتمادها كبديل عن مادتي الفورموكريزول والفريك سلفيت لعملية تحنيط لب السن. .

Abstract

Background: Well-adapted restorations with adequate marginal sealing are of extreme importance for the success of atraumatic restorative treatment, The present study was carried out to find if the mixing procedure affect the marginal seal of hand mixed and capsulated glass-ionomer in Class I cavities of 30 non carious primary molars.Materials and Methods:Standardized Class I cavity preparations were prepared in 30 extracted sound primary molars. The teeth were then randomly divided into two groups: Group I: filled with mechanically mixed (capsulated) glass ionomer cement (GIC). Group II: filled with hand mixed glass ionomer . After that the teeth were subjected to 250 thermal cycles with a 15 second dwell time in each, then sectioned to be examined under the stereo microscope.Results:The sealing ability of the GIC filling materials was determined by their ability to inhibit dye penetration. Data were analyzed according to t-test. The hand mixed GIC provides a better seal than capsulated GIC, there were no significant differences between the two studied groups in their resistance to dye penetration. Conclusion: Hand mixed GIC presented a better performance regarding microleakage in comparison to capsulated GIC.

Abstract

Abstract: Secretary immunoglobulin A SIgA , play an important role in mucosal immunity, and the salivary level change in response to infection ,social , psychological and physical stress, also the change in level of salivary IgA and other saliva properties include salivary pH, salivary flow rate SFR, and body mass index BMI in children with fixed appliances were measured .The aim of this work was to compare the values of SIgA, PH, SFR and BMI in children with and without fixed appliances. This work included 20 children (10 males and 10 females) with mean age 6 years old who were users of fixed space maintainer for at least 12 weeks, and 20 children (12 males and 8 females) without fixed appliances and with mean age = 6.7 years. The level of SIgA in saliva were assessed by ELISA test. The results revealed that the mean values of SIgA and SFR were higher in fixed appliance group than the group without fixed appliance, with statistical significant difference, but no statistical significant differences were reported for salivary pH and BMI between the studied groups. The results also showed a weak positive correlation between SIgA and SFR (r = 0.07) while negative correlation between SIgA and pH in fixed appliance children (r = 0.1). In conclusion, children with fixed appliances associated with high level of SIgA and SFR and the level of salivary pH and BMI do not correlated with fixed appliance.

Abstract

dental caries survey was conducted concerning 6-9 years old children in two different social areas in the city of Baghdad.The total sample composed of 180 (90 males and 90 females). Purpose of this study included the estimation of the prevalence of dental caries and its association with the socioeconomic background of children.Results showed that for the primary dentition dmfs and dmft values were higher for males aged 6-7 and 7-8 years in high socioeconomic class (7.8 & 4.2 , 9.7 & 4.7) than in low socioeconomic class (6.7 & 3.9 ,7.2 & 3.2) with statistically no significant differences ( p> 0.05). For children aged 8-9 years in low socioeconomic area the values were higher compared with those in high socioeconomic area for both sexes.For the permanent dentition the high social class showed higher prevalence of dental caries compared with their lower social class counter parts except females aged 8-9 years with low socioeconomic status recorded higher DMFS and DMFT values ( 2.66 & 2.6) compared to those in high socioeconomic (2.6 & 1.8), while the relation was not significant ( p>0.05).Generally the present study showed that the prevalence of dental caries for primary teeth was higher among children with low social class (dmfs & dmft) than those with high social class, while the results were reversed for the permanent teeth.

Abstract

Microbes are considered as the primary etiologic agents in endodontic diseases.Disinfection of the root canal is obtained by the combined effect of biomechanicalpreparation, irrigation and intra canal medicament. The aim of the present study wasto assess the antimicrobial activity of intracanal medicaments (formocresol andEndosepton) against two micro organisms (Streptococcus mutans and staphylococcusaureus) isolated from 15 necrotic pulps of primary molars indicated for pulpectomyprocedure. The samples were cultured, and purified using microbiological evaluation.Broth dilution test was performed in our study by preparing test tubes containing10 ml of BHI broth (pH. 7) which then inoculated with strains of the tested bacteriaand incubated at 37 C° for 24 h. After over night incubaction, ten fold dilution weremade in test tubes containing 9 ml of normal saline by adding 1 ml of the inoculum tothe first tube . Then from dilution 10-1 , 0.1 ml of cell suspension was added to 9.9 mlof formocresol and endosepton, then 0.1 ml was taken and spread on duplicates ofBHI agar plates at different intervals and incubated aerobically for 24 h. at 37 C°.Colonies on the plates were counted after incubation and CFU/mL (colony formingunit) was calculated. Our results indicating that there were no significant differencesbetween the intracanal medicaments, but there were high significant differencesbetween the intervals time of the study. We concluded that both materials had greatantibacterial effect against the pathogens commonly isolated from necrotic pulpaltissue of primary teeth.
