Abstract

The palatine rugae are irregular fibrous connective tissue ridges located in the anterior third of hard palate that extends bilaterally from the midline behind the incisive papilla. Rugae patterns play a role as positive identification of individuals in suspected cases in forensic dentistry. The aim of the present study is to identify and compare the rugae pattern in a sample of Iraqi population. Materials and method: 120 samples of maxillary casts were selected for 60 males and 60 females their ages ranging between (22-35) years old by using Thomas & Kotze classification for assessment rugae patterns. As a result of this study shows that rugae patterns has a unique individual imprint, differ in the number, symmetry between right and left sides, shape of rugae lines for each person with no significant differences for both sexes. This work conclude that rugae patterns can be used as additional method for identification as a personal print, and considered a characteristic to discriminate between individuals.

Abstract

Oral flora responsible for periodontal disease is polymorphic. The periodontal infection results either from the penetration of pathogenic microorganisms in the tissues, or even the activation of already existing germs, but not pathogenic under normal conditions. The aims of this study was carried out to evaluate selected bacterial agents causing periodontitis. One hundred eighty samples were examined in the present study. Clinical measurements of periodontal parameters used included dental plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment loss. The results of periodontitis were the most common anaerobic periodontal bacteria isolated from patients were peptostreptococcus prevotii which represented 15(8.3%) isolates, while prevotella intermedia, prevotella melani, prevotella disiens, Bifidobacterium sp., Fusibacterium mortiferum peptostreptococcus tetradius, and Wolinella sp. represented only 1 (0.5%) isolates.Also another anaerobic subgingival bacteria isolated from inflamed sites in patients were fusibacterium varium ,vellionella sp., campylobacter gracilis, capnocytophaga sp. ,peptostreptococcus magnus, peptostreptococcus micros, peptostreptococcus niger,peptostreptococcus anaerobius, staphylococcus saccharolyticus, streptococcus consellatus, and gemella morbillorum. Concerning to the results of this study the researcher concludes peptostreptococcus prevotii, prevotella intermedia, prevotella melani, prevotella disiens, Bifidobacterium sp., Fusibacterium mortiferum peptostreptococcus tetradius, and Wolinella sp. fusibacterium varium ,vellionella sp., campylobacter gracilis, capnocytophaga sp. ,peptostreptococcus magnus, peptostreptococcus micros, peptostreptococcus niger,peptostreptococcus anaerobius, staphylococcus saccharolyticus, streptococcus consellatus, and gemella morbillorum were the most common anaerobic periodontal pathogens isolated from patients in the present study.

Abstract

Caries is an infectious disease that is induced by the diet. Despite its decline in all age group on a worldwide basis, it is still a serious public health problem in children and its control should be a priority. It has demonstrated that dental caries can gradual reduce children's weight gain, which may be reversed after complete oral rehabilitation. The aim of this study was to investigate the association between age-specific body mass index (BMI-for-age) and dental caries among school children 7-12 years in Tikrit city. Material and method: A random sample of 390 school going healthy children aged 7-12 years were selected from different schools located in the Tikrit city. Height and weight for each child was recorded to obtain BMI-for- age. Dental caries was recorded (dmft, dmfs, DMFT and DMFS) according to WHO criteria. The data obtained was subjected to statistical analysis. The results showed that the underweight children were more likely to have caries experience than normal and overweight children for primary dentition (dmft 6.75 ± 0.56 and dmfs 17.21± 1.37) and for permanent dentition (DMFT 4.00 ± 0.58 and DMFS 6.48 ±1.23) with statistically no significant differences between the three groups.

Abstract

Problem Denture base dimensional changes were found with commercial theremocured acrylic resins. The dimensional stability of acrylic resin denture base is the main necessity effects the retention and stability of the denture. This study was conducted to measure the dimensional accuracy of experimental prepared material in comparison with control material before and after thermo cycling cured by water bath and microwave. In this stady the total (40) specimens of heat cure acrylic resin lower denture base were cured by water bath and microwave after addition poly vinyl pyrrolidone (PVP). (Experimental). Preparation of modified heat cured denture base acrylic resin was carried out by preparing of (PMMA) (80%) and poly vinyl pyrrolidone (PVP) (20%) and the liquid part composed of methyl methacrylate (MMA) monomer. Evaluation was made by measuring dimensional stability and accuracy. Distances were measured between (3) points marked on denture bases "AB, AC and BC" before and after thermo cycling for both control and experimental groups. The result of this study showed that there was no significant differences (p>0.05) between control and experimental groups at three point "AB, AC and BC" before and after thremocycling. Dimensional stability and accuracy was not influenced by addition of PVP to acrylic denture base resin before and after thermo cycling in both heat and microwave treatment.

Abstract

Purpose. The purpose of this in vitro study was to evaluate the effect of partial ferrule locations on the fracture resistance of endodontically treated maxillary canines restored with complete crowns. Material and Methods. Fifty extracted maxillary canines were sectioned 18 mm from their apices, endodontically treated, and divided into 5 groups of 10 teeth each. All groups were prepared with full shoulder crown preparations. the first group having axial wall heights of 2 mm around the preparation circumferences, the axial walls were circumferential, 360 degrees around the preparations (Complete group), the second, third, and forth groups the axial walls were continuous for 180 degrees (one half of the axial tooth structure) of Palatal, Labial, and Proximal groups, and the fifth group all axial tooth structure was sectioned to the level of the preparation shoulder (Level group). All prepared teeth were then restored with quartz fiber posts (RTD), composite resin (Multicore) cores, and complete metal crowns. The fracture resistance was measured in a universal testing machine at 135 degrees to the long axis of the tooth until failure. Data were analyzed by ANOVA and then by Least Significance Difference test (LSD). The mode of failure was determined by visual inspection of all specimens. Results. Significant differences (P<0.05) were found among the mean fracture loads of the test groups, and was 803.7 N, 747.7N, 347.3 N, 386.6 N, and 186.7N for the Complete, Palatal, Labial, Proximal, and Level groups, respectively. When the mode of failure was evaluated, all failure was an oblique palatal to facial root fracture for the groups with remaining coronal tooth structure. In the Level group, post debonding was the predominant mode of failure. Conclusion. The palatal axial wall was more effective than the labial or proximal axial wall in providing fracture resistance to force applied to the palatal aspect in endodontically treated teeth.

Abstract

Introduction The third molars are the most frequently impacted teeth in the human oral cavity .The unerupted teeth are not, in themselves, pathological lesion but may induce pathology. Impaction can be present in different patterns and levels. Decision of removal or retention of impacted tooth is a matter of debate . Aim The aim of the present study was to evaluate the prevalence of impaction, angular position of impacted wisdom , level of impaction, agenesis and the indications for extraction. Materials and Methods A sample of 880 patients( 498 males and 382 females ) with age range between 18 to 40 years old with the mean of 28.8 . The study took place in the hospital of surgical specialization in which all patients were evaluated clinically and radiographically by OPG . Of 880 patients 411pstients showed impaction of at least one tooth (table 3) .The total number of impacted teeth in the sample were 1100 and 57 missing teeth (table 4). Result Among 880 patients , 411 (46.7%) patients showed impaction of at least one tooth , the total number of impaction was 1100 wisdom teeth . of which 428 ( 38.9%) were in the maxilla and 672 (61.09%) were in the mandible. The most prevalent angular position was vertical angular (59.81%) followed by mesioangular (18.45%). Concerning level of impaction , Level C was the most prevalent in maxilla and mandible . Agenesis of third molar was seen in 57 teeth (1.61%). Of 1100 impacted third molar ,663 were subjected to surgical removal .The most common reasons ”indications” for patient referral to our surgical department were orthodontic reasons followed by pericoronitis, while the lowest was fracture mandible. Conclusion impaction pattern , the mandibular impaction is more prevalent than maxilla with vertical impaction is the commonest followed by mesioangular impaction while the inverted impaction is negligible. Level C impaction is the most common in both maxilla and mandible. Concerning the indication for extraction , the most common indication was orthodontic followed by pericoronits , caries with the lowest prevalent were mandibular fracture and lesions even when the lesion represent the absolute indication for extraction. Oral surgeon should build his decision to extract or not extract third molars on the most canonical scientific guidelines and what is best for each individual case.

Abstract

Foreign body can be defined as any matter that created out of scope of the body but inter the body due to injury, Plain radiograph, computed tomography scan ,magnetic resonance imaging and ultrasonography could be used to assess and localize the foreign body, In this case report we will explain a case of foreign body established in the maxillary sinus and how CT scan was useful in determine the position of this foreign body, the surgeon reported that computed tomography scan was useful in such cases, so it can be concluded that computed tomography scan can assess the size and shape of the precisely and can give the exact position of foreign body but the patient receive higher dose of radiation rather than the dose has been received from dental panoramic tomography.

Abstract

Periodontitis is an inflammatory lesion mediated by host-bacterial interactions which results in a non-resolving inflammation that leads to local connective tissue attachment loss from the tooth surface, loss of alveolar bone and ultimately tooth loss Indeed, periodontal disease is the leading cause of tooth loss in the western world and developing countries. The aims of this study was to estimate the relationships between periodontal disease and predisposing factors. One hundred eighty samples (paper point inserted into periodontal pocket) were examined in the present study . Patients were of both sexes(140 males and 40 females).Their ages ranged from 16-69 years old. Clinical measurements of periodontal parameters used included dental plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment loss . The results showed that periodontal disease was the most common in age group 20-29 years old and only a case reported with periodontal disease in 65 years old patients. According to sex distribution of patients, periodontal disease was mostly found in males than females. The periodontitis was more common in non-educated,treated ,smoking patients they living in rural area than educated,non treated ,non-smoking patients . they living in urban area.The most common anaerobic periodontal bacteria isolated from patients were peptostreptococcus prevotii which represented 15(8.3%) isolates, while prevotella intermedia, prevotella melani, prevotella disiens, Bifidobacterium sp., Fusibacterium mortiferum peptostreptococcus tetradius ,and Wolinella sp. represented only 1 (0.5%) of anaerobic isolates .Also another anaerobic subgingival bacteria isolated from inflamed sites in patients were fusibacterium varium, vellionella sp., campylobacter gracilis, capnocytophaga sp., peptostreptococcus magnus, peptostreptococcus micros, peptostreptococcus niger,peptostreptococcus anaerobius, staphylococcus saccharolyticus, streptococcus consellatus, and gemella morbillorum.
