Abstract

Early diagnosis of unerupted supernumerary teeth is very important. Detailed examinations and evaluations of these teeth with Three-Dimensional (3D) images are very beneficial in terms of treatment planning and avoiding complications, which may occur. 3D imaging in Dentistry offers many advantages with respect to diagnosis and treatment planning. The applications of software-3DCT images for detailed evaluation of impacted supernumerary teeth: location, number, morphology and positional area, to avoid their possibility complications by early choosing the proper surgical treatment. A descriptive study including 98 unerupted supernumerary teeth from 75 healthy patients between 10 and 43 years of age. Reasons for patients attendance included : malocclusion ,lack of eruption of permanent teeth ,prominence of gingival ,diastama, ,cystic lesion, caries and pain in different regions of dental arches, taking into account the variables of personal data, gender, age, location, morphology, number and positional area, related complications,3DCT scans study and correlated with surgical approaches and treatment. Incidence in impacted supernumerary teeth is higher among male patients (ratio M: F of 1.8:1) .They are most frequently located in the maxilla (64.28%) mainly in the premaxilla within the central incisors – mesiodens (40.82 %) were detected by 3DCTscans ,most of them classified under Type III ( 72.5%). Most cases present only single unerupted supernumerary teeth (77.33%). The conical shape is the commonest morphology (34.69%).The diastema registered the greatest proportion (40.81%) of complications cases .Surgical removal of these teeth was done by labial or buccal approaches in (45.91%) of cases. 3DCT radiographies achieved to diagnosis and determine the exact situations, identified morphology, determined number presented and determined the position types of whole impacted supernumerary teeth that they were proved surgically to be in the same locations, similar shapes, right number and correct anatomical positions. With less invasive surgical interventions and less operation time. Early treatment planning of the impacted supernumerary teeth, the exact diagnosis of anatomical location, shape, number, position of mentioned teeth is an important issue to avoid their complication in the future.

Abstract

Transverse test is considered to be appropriate for polymeric dental materials since compression and tension stresses are correlated to specific fractures that occur during flexural load. So the aim of the study is to evaluate the transverse strength of heat cured acrylic denture base material by using different surface treatment by laser treatment with diodes laser and air-abrasion AL2O3. The 60 specimens of heat cured acrylic denture base material were prepared for this study. They were divided into three groups according to type of the surface treatment and as follows: first group without any treatment (control group), second group is treated with air-abrasion (AL2O3). While third group is treated with Diodes laser, then each group subdivided into two groups according to addition of the soft liner: group a: specimens made from heat cured acrylic and soft liner, while group b: specimens made from heat cured acrylic only, each group consisted from 10 specimens. The results showed lowest mean values of the transverse strength for the control group than the specimens with AL2O3 group, and the highest mean values of diodes laser group but statically there was non-significant difference between the groups. In addition the mean values transverse strength of the soft liner bonded to the heat cured acrylic were higher mean than those without soft liner groups. Within the limitation of this study, there was no change in the transverse strength of the heat cured acrylic by using the diodes laser and air-abrasion AL2O3 surface treatment.

Abstract

The Parents consider tooth eruption as an important thing in the child's life development, and they have often showed their concern about the timing of eruption of teeth. The purpose of this study were to Estimate the average age for eruption time of Permanent 1st molar, central & lateral incisors in upper & lower Jaw (right & left) in both gender and to Compare the eruption time of these teeth between upper & lower Jaw ,right & left side ,male &female. This study was conducted at Al Ramadi City / Iraq, where the sample was consisted of “786” children (391 male & 395 female) of age 5.5 years to 10 years were they taken randomly from various schools. Eruption of various permanent teeth (1st Molar, Central & Lateral Incisors teeth) were noted in both jaws and both sides. In our study we found that the permanent 1st molars were the first permanent tooth that erupts in all children at the age between 5.87 – 7.96 years on both jaws and on both right and left sides with the mean age of eruption at 6.57 ± 0.55 years in lower jaw and 6.62 ± 0.53 years in upper jaw. In addition to that our study showed that the next permanent teeth to erupt were central incisors which erupt at the age between 6.14 – 8.93 years on both jaws and on both right and left sides with the mean age of eruption at 7.23 ± 0.61 years in lower jaw and 6.29 ± 0.57 years in upper jaw. Finally, the eruption of permanent lateral incisors were at the age between 7.66 – 9.93 years on both jaws and on both right and left sides with the mean age of eruption at 8.89 ± 0.56 years in lower jaw and 8.93 ± 0.55 years in upper jaw. The teeth erupted in female earlier than male and in the lower Jaw than upper Jaw. In the most cases the right lower teeth erupted earlier than the other quadrant of both jaws. In general, we found that there was delay in the time of eruption of nearly all the teeth that were included in this study.

Abstract

Type IV dental stone play an important role during fabrication of indirect dental restoration. It should be accurate in every respect, dimensionally stable over time, hard enough to with stand fabrication process resistant to the inadvertent abrasions caused by fabrication. The aim of present study was to evaluate the effect of microwave irradiation and die hardener application on surface hardness of type IV dental stone. Two commercial brands of type IV dental stone (Spofadental/ Czech, Zhermack/ Italy) were evaluated. 30 samples were prepared from each brand and left to dry for 24hr. After that divided into three groups, control group (10 samples without treatment), 10 samples subjected to microwave irradiation at 650 watt output power and 2450 MHZ for 10 mint. And 10 samples painted with die hardener. Surface hardness measured with Shore C (Durometer, Digital hardness tester). The die hardener application not affect surface hardness of both brands (P>0.05). However microwave irradiation increase surface hardness of Spofadental Type IV dental stone. But reduce surface hardness of Zhermack Type IV dental stone. After 24hr. of pouring Type IV dental stone (Spofadental / Czech, Zhermack / Italy) die hardener application not affect surface hardness. However surface hardness of Spofadental Type IV dental stone may be improved with microwave irradiation. But Zhermack Type IV dental stone showed reduction in surface hardness after microwave irradiation.

Abstract

Chronic periodontitis is the most prevalent oral inflammatory disease that affect teeth supporting tissues in response to microbial infection. A secretor is aterm applied to anyone who secret his/her blood type antigen into their body fluids as saliva in the oral cavity. Forty eight males were participated in the present research. Their age ranging from 35 to 55 years. The clinical periodontal parameters included Plaque index (PLI), Gingival index (GI), bleeding on probing (BOP) and Probing pocket depth (PPD) were examined also. .The secretory ABO blood groups from saliva by using Blood Typing Kit # 11 were assessed. After that the patients were divided into secretors and non-secretors and the comparisons were done between them. There was highly significance difference between secretory and non-secretory chronic periodontitis patients in all periodontal parameters (PI, GI and PPD), from the total sample the Proportional ratio for secretory chronic periodontitis group was 58.33% while the proportional ratio for the nonsecretary chronic periodontitis was 41.66%. Group O is the predominant type of ABO for both groups. Chronic periodontitis is more likely to occur in secretor ABO more than non-secretor ABO.

Abstract

The bound strength of metal resin interface of prosthesis is a key factor in determining the service ability of that prosthesis. The main objective of this study was to determine the effect of different surface treatment on the shear bond strength of Ni-Cr alloy (CB-Blando 72 alloy) and heat cured acrylic veneer resin (Vertex). Thirty disc shaped samples from base plate wax were prepared, the diameter of disc was (8 mm x 4.5 mm). After casting the metal, the samples were cleaned, finished and polished by silicon carbide abrasive paper with grit size (600 μm) and then the profilometer was used to determine the surface roughness of samples. Then the samples were divided in to three groups, each group contain (10) samples. The first group received no treatment and serve as control .The Second group received micro mechanical treatment using 250 μm Al2o3 .The third group recived micro mechanical treatment using 400 μm Al2o3. The acrylic was prepared as a round shape (8 μm) in diameter and (2 μm) in thickness, which was placed on the metal surface treatment, the acrylic was fabricated in the same conventional way for construction veneer resin. Then all samples was tested the shear bond strength by using Instron universal testing machine .The result from this study showed that, the first group was give low shear bond strength while the second group showed that the air abrasion with 250 μm Al2o3 give the highest shear bond values when compared with the third group which air abrasive with 400 μm Al2o3.

Abstract

Present of important anatomical structures in both upper and lower jaws make challenge during planning for implant procedures in the atrophic alveolar bone and to overcome this problem need bone augmentation which still complex and difficult procedures make it not accepted by large number of patient. In this study we spot light on the teeth implant in an area where short bone or insufficient height of alveolar ridge and inclined alveolar ridge so when we place implant should be tilted either palatelly, mesially or distally in bone around and we compare the success rate between angled placed implant and up right placed implant. 61 patients came to clinic asking for tooth or teeth implant, 300 implant fixtures were placed in both upper and lower arch 203 implants were straight and 97were tilted. After 24 months follow up in the upper and lower alveolar arches of dental implant (97.54%) of upright implant were success and (97.94%) of tilted implant were success. Results indicate that the use of tilted implants effective and safe method over bone augmentation procedures and nerve transferring.
