Abstract

Aims: The aims of the study are to evaluate the radiographical views, OPG and periapical views on the changes in peri- implant bony tissue around dental implant at time of placement and another reading after 16 weeks before functional prosthetic loading and regard it as a prognostic parameter. Material and methods: Nineteen cases with 24 implant were enrolled for standardization. Radiographical measurement undertaken by a periapical and OPG radiographs after implant placement, then after16 weeks later, again a second periapical and OPG radiographs were taken for measurements using Dimaxis 3.2.1. Software program to estimate marginal bone height of both sides of implant and its changes during times of evaluation. Results: 19 medically fit patients, male and female with age 22-65 years, twenty four implants with average bone loss 0.59 mm mesialy and 0.60 mm distally at T0 as standered base line in compared to 0.98mm mesialy and 1.11mm distally at T1as average bone loss. There was a significant bone resorption in both sides in relation of implant size and in comparison to time of placement and after 16 weeks according to statistical analysis. Conclusion: OPG and periapical views are a good parameter for evaluation of successful implant and monitoring of the prognosis and stability and durability, as these radiographs more available in most dental centers and clinics with less cost.

Abstract

The purpose of this study was to determine the more accurate method for predicting the width of unerupted mandibular premolar of mixed dentition patients, whether by the multiple regression analysis method or by radiographic measurements of deciduous molars width method. Multiple regression analysis method was performed on data derived from 108 children (62 females and 46 males) aged 9–12 years old. These children were selected from primary schools located in different areas of Mosul City. All subjects had normal Class I molar relationship with mixed dentition (the right and left permanent centrals, laterals and first molars, and right and left primary canines and first and second molars). The data were statistically analysed using Statistical Package for Social Statistics. The results revealed that there were no significant differences in mesio–distal crown diameter between right and left sides of both unerupted premolars and deciduous molars. All the teeth in males were larger in mesio–distal crown diameter than females. Also, the results of the present study indicated that there was a positive correlation between most of the teeth, individual teeth and groups of teeth. There was a difference in the means between the mesio–distal crown diameter of deciduous molars and unerupted premolars. The present results used to generate a formula “linear regression equation” that can be used clinically to affect prediction depending on the mesio–distal width of individual deciduous molars.

Abstract

Introduction:The pulp polyp (PP), also known as chronic hyperplastic pulpitis orproliferative pulpitis, is a type of inflammatory hyperplasia. It occurs in a vitaltooth with a good blood supply when the pulp has been exposed to caries ortrauma.Objective: The aim of this study to evaluate different radiographic periapical changesof primary and permanent dentition in clinically detected pulp polyp patients.Materials and Methods: Patients who were clinically diagnosed with pulp polypwere subjected to radiographic examination. Digital intraoral periapicalradiographs of 70 patients with pulp polyp were taken. Various periapical changesof primary and permanent dentition in the digital radiographs were recorded . Thedata obtained was subjected to statistical analysis using SPSS version 16.0.Result: All 70 patients showed definite periapical changes. Out of which periodontalligament (PDL) space widening was seen in all 70 cases (100%), lamina duradiscontinuity was observed in 50 cases (71.43%), periapical rarefying osteitis wasnoted in 20 cases (28.57%), condensing osteitis was accounted in ten cases(14.29%), periapical granuloma was observed in six cases (8.57%),hypercementosis was accounted in nine cases (12.86%) , root resorption andperiapical cyst was observed in eight cases each (11.43%).Conclusions: The results of the present study showed that majority of the pulp polyppatients observed at young age group in both gender and the majority of the pulppolyp patients were associated with definite periapical changes that suggestedbeing a periapical lesion.
