Abstract

Background: The use of osseointegrated fixtures in dentistry has been demonstrated both histologically and clinicallyto be beneficial in providing long term oral rehabilitation in completely edentulous individual. Most patients sufferfrom denture instability; particularly with mandibular prosthesis, the use of dental implant will be benefit significantlyfrom even a slight increase in retention. The concept of implanting two to four fixtures in a bony ridge to retain acomplete denture prosthesis appealing therefore, as retention, stability and acceptable economic compromise tothe expanse incurred with the multiple fixture supported fixed prosthesis .Materials and methods in this study the sample were eight patients selected from a hospital of specialized surgery,these patient were wearing a mandibular implant retained over denture for two years these patients having MIR-ODwith Bar-clip, ball-cup and O- ring attachments. Preparative radiography was obtained for this patient from thecenter .these radiograph was taken to the patient at time of insertion. The second radiograph image was taken tothe patient after two years of function with prosthesis. .the scanned images were transfer to special folder in acomputer then analysis of bone loss done using Dimax software. After that an accurate calibrations of crestal bonemeasurement were analyzed for both groups of Radiography .Results it was appeared that the amount of bone loss in ball and bar designs (of mandibular Implant retainedoverdenture) were within the criteria of successful rate of bone loss during the period of examination, and there wasstatistically significant difference between both types of anchorage system.Conclusions The amount of bone loss was 0.1 mm after two years follow up, and it was within the acceptable limits ofbone lose. A significant difference appeared between both designs of MIR-OD, Ball and bar designs

Abstract

Aims: the study was planned to assess the value of the change among four pubertal age groups of Class l occlusion. Materials and Methods: The sample subjects were comprise of the flowing groups: 11yeas(23 males&25 females), 12years(19 males &22 females), 13years(22 males &28 females) and 14years(22 males &22 females). Each individual radiographed with cephalometric film. The cephalometric films traced and the mandibular lengths ( Ar–Pog, & Go–Gn & Ar–Go) were measured. The data subjected to the descriptive and variance statistics at 0.05 significant level. Results: The findings disclosed that the mandibular lengths (Ar–Pog, Go–Gn &Ar–Go) were significantly greater value at 14years age group as compared with 11,12,&13 years age groups. The sex variation appeared insignificant change among the four age groups for the mandibular lengths. Conclusion: The increase mandibular length at age 14 years can be regarded in relive the crowding at 11,12, &13 years age groups for both sexes

Abstract

Aims: the aim of this study is to determine a calibration factor to eliminate the distortion in the linear cephalometric measurements. Materials and Methods; the study was performed on the 5 dry skulls, the first skull contained 12 radiopaque markers fixed at different plains, and radiographed by digital cephalometric x-ray machine. The X and Y axes of the shadow of each radiopaque marker used to estimate the calibration factor. Eight linear distances measured directly and radiographically on the conventional cephalographs of the 5 skulls to evaluate the detected calibration factor. Results; the results showed no-significant difference (p > 0.05) between the direct and calibrated radiographic measurement on the digital and conventional cephalographs. whereas significant difference was found between the conventional cephalometric linear measurements as compared with direct anatomical linear and the conventional cephalometric linear measurements with those measurements manipulated with the estimated calibration factor (p < 0.05). Conclusions; this study found that the conventional cephalometric linear measurements could be reliable as that of digital cephalometric linear measurements, if it's calibrated by the calibration factor (1.08) which is estimated by the present study.

Abstract

Aims : the study aims is to examine the inter- observer variability in radiographic interpretation of the variable position , shape and appearance of mental foramen. Materials and Methods: Four examiners, two dental radiologists and two oral surgeons evaluated 30 panoramic radiographs to evaluated the position, shape and appearance of mental foramen. Results: The most frequent position of mental fo-ramen was between first and second premolars then followed by those below the apices of the first and second premolars and the most frequent shape of mental foramen was irregular where separated type is the frequent appearance of mental foramen. For agreement there was no significant difference between two radiologist for position ,shape and appearance of mental foramen , but with a significant difference was found between four observer, for the position of mental foramen. Conclusions: The study concluded that the position of mental foramen is most commonly below and between the pre-molar teeth and the most frequent shape are irregular and appearance separated type

Abstract

Background: Chronic renal failure can give rise to a wide spectrum of oral manifestations, affecting the hard or softtissues of the mouth. The majority of affected individuals have disease that does not complicate oral health care. Themain aim of this study is to assess the response to therapy and to determine the radiographic manifestations in teethand jaws of individuals with chronic renal failure undergoing hemodialysis and to find possible preventive andtherapeutic strategies.Materials and methods: Thirty male patients with chronic renal failure who were continuously receiving therapy withongoing hemodialysis were included in this study and were divided into two subgroups according to the period oftherapy (those who had renal dialysis for less than a year, and 1 to 2 years). All patients were requested forpanoramic (OPG) radiographs with standardized parameters according to user manual of the machine thenquantify the frequency of abnormal dental and periodontal radiographic findings in both arches i.e. the alveolarbone resorption, presence of hypercementosis of the roots, lamina dura reduction or loss and dental condition, thenthe data were analyzed statistically by comparison with control normal subjects.Results: It has been established that the duration with the increase the abnormality in dental and periodontalradiographic findings as alveolar bone resorption, presence of hypercementosis of the roots, lamina dura reductionor loss, as well as other dental diseases.Conclusion: Panoramic radiographic view used in this study considers as a good monitor for jaw and dental changesassociated with patients affected with chronic renal failure treated with hemodialysis, and the results showed strongcorrelation between duration of hemodialysis and all studied variables. Clinicians should use oral health assessmenttools to determine individual treatment and approaches to promote the oral health of patients undergoinghemodialysis and improve their quality of life

Abstract

This study aimed to estimate the mature root length of first premolar by using the root of first molar as a reference through the panoramic radiograph.The sample of this study included 102 panoramic radiographs of Iraqi Arab subjects with an age ranged between 17-25 years. The root length of both the first premolars and first molars are measured on good diagnostic quality panoramic radiographs by using the Planmeca Romexis Viewer software. Pearson’s correlation coefficientwas used to determine the relation between the root length of first premolar and that of permanent first molar. Regression equation was used to determine the questions that predict the length of mature root of first premolars. Paired t-test was used to compare between the actual and predicted root length.The findings showed high correlation between the root length of first premolars and that of permanent first molars. Hence, the root length of permanent first molar can be used as predictors for root length of first premolars.

Abstract

Alveolar bone loss is the atrophy of maxillary and mandibular bone that underlines and support the teeth lead to reduction in bone height and volume. The sample of this study was collected from patients who attended Al-Mammon center for specialist dentists. The patients usually complaing from bleeding gum, discomfort on eating and relative mobility of teeth. In this study 60 male patients with age between 20-49 years were selected and divided into three groups to assess bone loss by the aid of digital panoramic radiographs in the upper and lower anterior teeth. The results revealed that bone loss is more in lower anterior teeth than in upper anterior teeth in most of the age groups.

Abstract

Background: Pulp stones (denticles) are discrete calcified aggregates that occur most frequently in the dental pulp.It was found in healthy, diseased and sometimes in erupted teeth. Its number appears to increase with increasingage. It is usually detected during radiographic examination as radiopaque masses of variable size and shape. Theaims of this study were to calculate the prevalence of pulp stones in young Iraqi adults by using digitalorthopantomgraph, and to report any associations between occurrence of pulp stones with, gender, tooth type,and dental arch.Subject, Material and Method: A total of 390 digital panoramic radiographs were collected from oral diagnosisdepartment /College of Dentistry for Iraqi sample, University of Baghdad and Al-Karkh General Hospital. The samplecomposed of 169 male and 221 female with mean age (26.9 years). About 10510 teeth were evaluated; pulp stonesscored as present or absent, number of stone and associations with, gender, tooth type and dental arch wererecordedResult: From 390 (OPG) total of 3758 teeth were examined, 136 patients have pulp stone present in (276) teeth.According to gender, 75 female with 143 teeth (51.8%) and 61 male with 133 teeth (48.1), that is mean there was nosignificant difference of ( pulp stone occurrence) found between female and male. Their presence were seldomfound in the premolars 18 teeth (7%) but was much higher in the molars 258 teeth (93%) and the difference isstatistically significant. Pulp stone occurrence was significantly more common in the first molars than in the secondmolars and in the first premolars than in the second premolars in each dental arch. No difference between the twoarches could be identified.Conclusion: Pulp stones are not only incidental radiographic findings of the pulp tissue but may also be an indicatorof some serious underlying disease. On the other hand, they may provide useful information to predict about thesusceptibility of patients for other dystrophic soft tissue calcifications such as urinary calculi and calcified atheromas

Abstract

background: Pneumatization is an activity that occur physiologically in all paranasal sinuses during the growing period, causing them to increase in volume. Pneumatization of the sinus after extractions can have various treatment-planning implications, such as reduction of the alveolar bone height available for implants, orthodontic miniscrew or complication in preprosthetic surgery.Aim of the study: To find the correlation between rate of pneumatization of maxillary sinus and time after extraction of the related teeth. Subjects, material and methods: A total of 96 panoramic radiograph used to measure the supero-inferior differences of the sinus floor position by using interorbital line and 2 zygomatic lines as a reference lines after one to more than 10 years of the unilateral extraction of one of the maxillary second premolar, first molar or second molar tooth of 48 experimental subjects to make a comparison with the contralateral 48 control subjects with bilateral present mentioned teeth. Results: 48 control subjects show no statistically significant mean difference between the one side and the adjusted contralateral side. There was statistically significant increase in the side of the missing tooth compared to that of the contralateral side. The site of the missing tooth is associated with an average increase in distance of 2.53mm from the comparable 0.22mm in the control subjects, and this change was statistically significant. There is a moderate strong positive linear correlation coefficient between time interval and maxillary sinus pneumatization r=0.45 P<0.001.Conclusion & discussion: The pneumatization of the maxillary sinus is related to the time interval since extraction. The longer the time interval the more maxillary sinus pneumatization.
