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: 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.

Abstract

Aim of the study: To evaluate the position of impacted mandibular third molars and its relation to the inferior alveolar canals by the aid of panoramic radiographs.Materials and method: The study includes (246) panoramic radiographs with (444) impacted mandibular third molar teeth that are collected from different oral and maxillofacial surgery units belong to patients with the age between (20-35) years who seeks for help to remove their impacted mandibular third molar teeth in order to evaluate the relationship between the position of impacted mandibular third molars and its relation to the inferior alveolar canals by the aid of panoramic radiographs. Impacted mandibular third molar teeth position were classified as vertical, horizontal, mesioangular, and distoangular (Winter’s classification)and the radiographic relationship of the root apex of impacted mandibular third molar to the inferior alveolar canal was categorized as :below,superimpose,grooving and none of them(none).Result and discussion: The majority of impacted mandibular third molar teeth was of mesioangular position (35%), then the vertical position (29%), distoangular (20%), and the horizontal position (16%) in both gender and males has a higher percentage than females.Ingeneral,superimposition relationship between impacted mandibular third molar teeth and inferior alveolar canal is the highest (39%) in most of the cases among the other types of relation, then to a lesser extent was below the roots (31%), grooving (25%), and lastly, none (5%).The alveolar canal is mostly below the vertical and horizontal type of impaction. The alveolar canal is mostly superimposed on the roots of mesioangular and distoangular type of impaction. Grooving relation ship is most common with mesioangular impacted mandibular third molar.

Abstract

Aims: To determine the real not radio graphical proximity of mandibular third molar tooth to the inferior dental canal (IDC) using panoramic radiograph. Materials and Methods: 144 mandibular third molars were evaluated by panoramic radiography. The teeth were grouped into erupted vs. un erupted further subdivided by tooth angulations. The real distance from the most inferior aspect of the mandibular third molar tooth to the superior border of the inferior alveolar canal (IAC) was calculated regarding to the reference object used. Descriptive statistics were performed as well as a t test was performed to compare erupted and unerupted teeth, and ANOVA was used to determine a significant difference where exists based upon tooth angulations. In addition, intra observer analysis was done to ensure the standardization of the radiologist interpretation. Results: The mean distance from erupted mandibular third molar teeth to the inferior alveolar canal was 0.23mm. This distance was significantly different from unerupted teeth (P = .000). The mean values for unerupted teeth were negative values which indicated that the apices of all teeth measured was below the superior border of the canal –1.26 mm and as follows: Mesioangular–1.32 mm, vertical – 1.34 mm and –1.04mm for horizontal impactions. Statistically there was no significant positional difference between the impaction groups (P = .835). In general there was a significant difference in third molar position between those age equal and less than 22 years old and those equal and over 23 years old. Conclusions: Unerupted mandibular third molar teeth (mostly vertical impaction) are closer to the inferior alveolar canal than erupted teeth and persons in general of an age equal or less than 23 years old have a closer lower third molar to mandibular canal than other ages and there is no significant relation between this age group and any of impaction types.

Abstract

Background and objectives: measuring the distance between the lowest point of the maxillary sinus floor and maxillary alveolar bone crest seen in the digital panoramic images and the effect of alveolar bone resorption to evaluate the clinical benefit of using software measurement program to measure the height of the alveolar bone in the region of maxillary sinus.Method: Digital panoramic images were analyzed using the software computer programs that existed in the system to measure the distance from the lowest point of the maxillary sinus floor and maxillary alveolar bone crest. Images were divided into four groups (1st group dentulous cases, 2nd group single dental extraction, 3rd group multiple dental extraction, 4th group edentulous cases) and each group consist of 50 panoramic images.Results: The mean distance of sinus floor to bone crest in fourth group cases was approximately half of the distance in first group due to extraction of teeth and there was highly significant difference (P<0.001) between first group, third group and fourth group images, and there was significant difference (P<0.005)between first group and second group images.Conclusion: It was concluded that the objective assessment of alveolar bone height and its 2-dimensional relation to maxillary teeth was greatly helpful by applying the software program.
