Introduction: Dental panoramic radiography, also known as orthopantomography (OPG) is a commonly performed investigation for assessment of dental pathologies, including dental impactions. OPG in case of dental impactions can assist in determination of the location and angulation of the 3 rd molars and their relation to the adjacent teeth and structures. The aim of the study was to investigate the distribution of impacted third (3rd) molars in dental students of the Hai'l Region of Saudi Arabia. Material and Methods: The study population of this observational study comprised 170 male and female dental students of the College of Dentistry (CoD), University of Hai'l (UoH). On induction, the study participants underwent clinical examination and OPG. The clinical and OPG assessments assisted in determining the presence of impaction and patterns of angulation of the 3 rd molars in maxilla and mandible. Results: From the 170 OPGs, 95 (55.8%) showed at least one impacted 3 rd molar ...

Objective: The aim of present study is to know the association between types of impaction and jaws in males and females. This study also evaluates the prevalence of impaction according to age in maxilla and mandible. Material and Methods: The orthopantomograms of 198 subjects were taken from Planmecca PM 2002 cc Proline Panoramic X-ray unit at Kvp (60-80), 10 mA at exposure time 18 second. The orthopantogram evaluated for type of impaction as per Winter's classification and related findings were recorded. Results: The recorded data is analyzed by using Statistical Package for Social Sciences (SPSS) version 21.0. The maxillary right and left side is more predilected for vertical impaction in male and female population and it was statistically significant (p<.05). The mesioangular impaction is most common impaction in mandible and it was statistically non-significant (p>.05) in either gender. In all age groups, vertical impaction is most common type of impaction in maxilla however mesioangular impaction is most common type in mandible. Conclusion: The vertical impaction is most common type of impaction in maxilla and mesioangular impaction is most common type in mandible in all age groups and gender.
Demographic Study on Tooth Impaction In A Malaysian Sample
2019
Failure of tooth to erupt into the dental arch within expected time is referred to as impaction. The most common reasons for tooth impaction include tooth follicle displacement, impaction due to crowding, tooth may be missing and infrequent extraction of lower first and second molar. Other reasons include retention or premature loss of deciduous teeth and other causes. The most commonly affected teeth are the lower third molars, maxillary canines, maxillary second premolars and supernumerary teeth. The aim of this study was to determine the prevalence of impacted tooth through Orthopanthomograph (OPG) images among patients attending the Polyclinic Faculty of Dentistry (FOD), IIUM Kuantan Campus. A retrospective study was carried using OPG images. Of the 2722 OPG images, 1248 OPGs that fulfilled the inclusion criteria which were taken from patients who attended at Polyclinic of FOD from 1 April 2009 until 31 May 2012. Then, it was classified into the types of tooth impaction accordin...

Aim. To evaluate the prevalence of impacted teeth in Saudi patients and compare between male and female subjects. Method. This cross-sectional study comprised of Saudi patients who attended dental clinics in major hospitals in the Eastern Province of Saudi Arabia. Patients’ dental records and panoramic radiographs were reviewed retrospectively. Impacted teeth excluding third molars and spaces occupied by primary, permanent, and transmigrated teeth were recorded from panoramic radiographs. The Pearson chi-squared test was performed to determine gender differences regarding impacted teeth and spaces occupied by other teeth. Results. The study included radiographs of 539 patients with a mean age of 23.3 ± 10.8 years. Seventy-one patients (13.2%) had at least one impacted tooth. The total number of impacted teeth was 115 in the sample, out of which 91 (79.1%) were in the upper arch and 24 (20.8%) in the lower arch. Fifty-eight maxillary canines (50.4%) were impacted making them the most...

Introduction: The third molar is undoubtedly the most variable tooth in the human dentition, and also the most common tooth to become impacted due to it being the last tooth to erupt into the dental arch The aim of research is to obtain the prevalence of the mandibular third molar (M3) impaction among the patients attending the Radiology Clinic. Methods: The type of research conducted was a descriptive research. The sampling was purposive, drawn from a population of 1451 digital panoramic radiographs taken from January – December in the year 2010, of which 392 samples were included in the survey, with patient ages ranging between 18 – 59 years at time of exposure. The position of the M3’s was assessed using the Pell and Gregory and, Winter’s impaction classification. Results: The prevalence of impacted mandibular M3’s in this study is 76.8% overall. Of the impacted mandibular M3’s present, 76.1% were bilateral impactions and of these bilateral impactions 50.7% are similar in impacti...

Aim: To assess the dental status of elderly patients examined in the clinical dentistry course of a Brazilian public university. Methods: An observational and descriptive study based on the analysis of panoramic radiographs. The sample consisted of 60 elderly patients who met the inclusion criteria. Two observers who had been trained in appropriate conditions performed the radiographic analysis. Data were stored in a specific form, recorded in a database and analyzed using descriptive statistics (measures of central tendency and variability) and inferential statistics (Mann-Whitney U test, Kruskal-Wallis test, Chi-square analysis and calculation of the Cramer’s V coefficient). Results: Most patients had at least one tooth in the oral cavity (71.7%), while 28.3% were totally edentulous, an average of 10.5 teeth per individual. The average number of teeth was 11.36 in males and 9.89 in females. The number of healthy teeth was 328 (5.47 per patient). In this study, 88.3% of the subject...

The permanent teeth impaction in young patients from the northeastern of Romania
International Journal of Medical Dentistry, 2018
This study performs a clinical, radiological and statistical evaluation of permanent teeth impaction on a sample of young patients from the North-eastern region of Romania. 67 orthodontic patients (29 boys and 38 girls), aged 6-37 years, were selected randomly during 1991-2010. Data from orthodontic records were evaluated according to social parameters, oral status, etiological causes, clinical features and treatment options. Statistical evaluation was done with the SPSS 20.0 package. The cuspid impaction was most frequent in girls (68.40%) and in boys was the central incisor impaction (55.20%). The most common was the single tooth impaction in upper arch (85.10%) and the severe impaction (76.10%). We found statistically correlations between the direction and localization of impaction and types of impacted teeth (p=0.002). 4.14:1 ratio was established between the conservative and the radical treatment. The risk factors (OR=1-5) and predictors for the extraction of impacted teeth (HL test, p=0.000) were identified.

OPG in case of dental impactions can assist in determination of the location and angulation of the 3 rd molars and their relation to the adjacent teeth and structures. The aim of the study was to investigate the distribution of impacted third (3rd) molars in dental students of the Hai'l Region of Saudi Arabia. Material and Methods: The study population of this observational study comprised 170 male and female dental students of the College of Dentistry (CoD), University of Hai'l (UoH). On induction, the study participants underwent clinical examination and OPG. The clinical and OPG assessments assisted in determining the presence of impaction and patterns of angulation of the 3 rd molars in maxilla and mandible. Results: From the 170 OPGs, 95 (55.8%) showed at least one impacted 3 rd molar with significant differences between males (30; 31.5%) and females (65; 68.4%). The proportion of impacted mandibular 3rd molars was 2.3 times higher in comparison to the impaction of maxillary 3rd molars. Both in mandible and maxilla, the most common patterns of 3rd molar angulation were vertical. Among females, vertical angulation remained the most common pattern of impaction followed by mesio-angular angulation. Among males, horizontal impaction remained the most common pattern of impaction followed by same numbers for vertical and disto-angular angulation. Conclusion: The results show a high frequency of 3 rd molar impactions among dental students of the Hai'l Region of Saudi Arabia. The proportion of 3rd molar impactions were higher in female students and mandible. Surgical removal of 3rd molars should only be reserved for impactions associated with clinical complexities.
