Results: The association between presence of caries (p=≤0.001) and external resorption (p=≤0.001) in second mandibular molar with depth of impaction of adjacent an impacted third molar, ramus relationship of third molar with presence of external root resorption in second molar (p=≤0.001) and presen...
Prevalence and Patterns of Impacted Maxillary third Molar in a Private Dental Institution
SciDoc Publishers, 2021
Tooth impaction can be defined as that failure of the tooth to erupt into its normal physiological position and oftentimes, it is associated with a third molar. Third molar is also known as wisdom tooth, meaning it is the last tooth to erupt into the oral cavity even in the age of adolescent or adulthood. Although third molar impaction remains indefinitely asymptomatic, some individuals may be presented with tenderness and swollen gums. Impacted teeth are commonly treated with tooth removal. Conservative approach is recommended in asymptomatic cases and when the risks of the procedure outweigh the expected benefit. The aim of this study was to investigate the prevalence and pattern of maxillary third molar impaction, angulation and level of eruption among patients treated in Saveetha Dental College. Data collection was done in a university setting. Data regarding patients having impacted teeth were retrieved after analyzing 86000 case sheets. The following parameters were evaluated based on the dental records; age, gender, level of eruption and angulation pattern. Radiographs and intraoral photographs were used to assess the patterns of maxillary third molar impaction. Excel tabulation and SPSS version 23 was used for data analysis. The statistical test used for the demographics was frequency, percentage and for tests of association between categorical variables was Chi-square test. P value less than 0.05 was considered as statistically significant. Women had more prevalence (58.5%) of impaction than men and was seen most in the age group of 21-40 years. 64.6% and 35.4% of the total teeth were 18 and 28, respectively. The most common angulation of impaction in maxilla was vertical (55.4%). Position C impaction had greater occurrence (61.5%) compared to other two levels of impaction. No significant difference was found between right and left sides in maxilla, (p=0.447). There was no significance of angulation and level of impaction with respect to age and gender. Within the limits of the study, impacted maxillary third molars were more prevalent in female and younger patients. Vertical angulation and level C position were more frequently seen in impacted maxillary third molars.

Background and aim: An impacted tooth is a tooth that did not grow on its expected time because of an incorrect position or lack of space. The impacted third molar is the most common impacted tooth. In the present study, the presence of the impacted third molar teeth and their complications in the panoramic radiography of patients were evaluated. Methods and materials: The frequency of impacted third molars, in two jaws and two genders, their position (impaction depth and angulations), their influence on adjacent teeth and their relations to inferior alveolar canal were evaluated in 2000 panoramic radiography of patients who were over 20 years old. Results: 333(16.65%) patients [161(48.3%) men and 172(51.7%) women] with mean age of 30.32 ± 7.22 years (between 20-68 years old) had impacted teeth. 313 cases only had impacted third molars, 16 cases had other impacted teeth and 4 patients had both impacted third molar and other impacted teeth. Prevalence of impacted wisdom teeth is in mandible more than maxilla and in women more than men. The mesioangular angulation in mandible and upright angulation in the maxilla were the most common angular position. Type B in the mandible and type C in the maxilla were the most common types of impaction's depth. Most of the mandibular and maxillary impacted third molars showed complete root development. Higher frequency of distal caries or defects of the adjacent second molars was found in the mandible. Conclusion: Frequency of impacted third molars in mandible was more than maxilla. Also impacted third molars were found in women more than men. With regard to mandibular third molars, mesioangular and type IB were the common pattern.The relationship between the position of the tooth and distal caries of second molar will be an interesting finding and has clinical importance.
Evaluation of the clinical effects of impacted lower third molar tooth on adjacent oral tissues
Brazilian Dental Science
Objective: Impacted tooth develops when the tooth fails to erupt into its anatomical functional position. The aim of this prospective study was to find out common clinical effects of impacted lower molar on adjacent tissues and to evaluate the relationship between signs and symptoms of impacted tooth as regards gender and age respectively. Material and Methods: Data for this study were obtained using a well-structured questionnaire at the Teem Dental Hospital Warri, Nigeria. The data included age, sex, and clinical features of patients with confirmed diagnosis of impacted lower third molar following clinical examination and radiographic investigation. Data were analysed and chi-square was employed. Results: A total of 131 patients were examined, 57 (44.5%) were males and 74 (56.5%) were females within the ages of 10-40 years. Patients within the ages of 21-25 years had the highest frequency (32.1%) of impacted lower third molar. It was observed that impacted tooth had a gender predilection towards females than males. Inflamed gingivae around lower 3rd molar 60(45.8%) and pain on the lower third molar 72(55.0%) were most predominantly associated with impacted third molar teeth. No significant association was observed between age (0.909) and gender (0.461) against symptoms of impacted tooth but significant association (0.001) between age and sign was observed. Conclusion: The most commonly associated effect of impacted third molar is inflammation of the adjacent gingivae alongside pain around the lower third molar. Prevalence of impacted molar tooth was gender based with age being a predilection factor in its signs of presentation.

Objectives: 1. To identify the frequency of third molar impaction. 2. To evaluate the pattern of third molar impaction. Methodology: Six months records of the Digital Orthopantomographs of patients attending department of Oral Medicine and Radiology, SDM Dental College and Hospital were randomly collected. Age range of the patient being 19 years or older. Orthopantomographs were reviewed by the single examiner using a X-ray viewer. Third molar was considered impacted if the tooth is not in functional occlusion or if roots were not fully formed. Angulation was assessed by measuring the angle between the long axis of the impacted third molar relative to the long axis of the second molar using orthodontic protractor. The results were tabulated and sent for statistical analysis. To test the significance Chi square test was applied. The p value was set to 0.05 Results: These results show that third molar impaction was most common in mandibular arch than in maxillary. Most common type of impaction in the maxillary arch and mandibular arch was vertical type. Conclusion: Third molar impactions are most common in the mandibular arch than maxillary with the higher incidence rate on the left side than right. Most common type of impaction in the maxillary and mandibular arches was vertical impaction followed by mesioangular
