“…Kumar et al found that 52.89 percent of Eritrean citizens were having mesioangular impacted molars [10]. In 2016, studies showed the prevalence of mesial-perspective impaction in 47.1% of patients, using data provided by Nagaraj and co-authors in addition to many different researchers [11][12][13][14][15][16]. According to studies by Al-Dajani et al and Yilmaz et al, vertical impaction is more frequent [17,18].…”

Even while certain forms of mandibular impactions (such as inverted molars) might be considered unusual findings, mandibular impacted teeth are really one of the most regularly seen dental abnormalities. Two female patients' mandibular third molars were discovered to be inverted during a regular inspection, and two such examples are reported here in this article. Both patients underwent routine radiographic examination. Cone beam computed tomography and orthopantomogram were requested to evaluate the state of the bone and to check for any abnormalities, and inverted impacted teeth were discovered. A tooth is said to be inversed when it is placed reversed and seated upside down. Ascending ramus is the most common site for third molars in the mandible. It is also possible for a maxillary tooth to get impacted and for the tooth to be pushed all the way to the orbit's floor, though mandibular impacted teeth are more common. Only a few cases of inverted and impacted mandibular third molars have been reported in the literature. No definitive treatment protocols exist for the removal of inverted teeth. The safest protocol is conservative treatment in which the teeth are not extracted until they produce pathological signs.

“…39 These reports were confirmed in 2016 by Nagaraj and co-authors 40 presenting mesialangle impaction in 47.1% of patients, as well as many other researchers. [41][42][43][44] In the studies of Al-Dajani et al 45 and Yilmaz et al 46 vertical impaction was found to be the most common position. The first team showed the occurrence of this impaction in 40.7% and mesioangular impaction in only 7.1% of patients; the second team showed vertical impaction in 53% and mesioangular impaction in 29% of patients.…”

Background and Aim: Dental diseases now-a-days are emerging swiftly thus making its control and prevention a tedious task. The outcome of dental diseases is boundless extending from pit and fissure involvement till development of malignancy. Thus, the prevention as well as control of dental diseases has gained importance. A thorough knowledge of prevalence of disease along with profound clinical examination are two most criterion for determining the presence or severity of disease. Dental diseases can be prevented by early diagnosis followed by immediate treatment. However, the progression as well as the severity of the disease is determined by calculating the prevalence stroke frequency of occurrence of the particular diseases. In view of above mentioned background, the study was done to determine the frequency of occurrence of various dental diseases in Western Uttar Pradesh population. However, the present study was not community-based but rather commenced radiographically. Materials and Methods: The present study was undertaken to estimate the prevalence of various dental diseases radiographically. The dental diseases considered in the study are dental caries, periodontal diseases such as horizontal bone loss, vertical bone loss, presence of root stumps and impaction status. In the study, a total of 1500 radiographs were selected randomly and evaluated and the prevalence of various above mentioned dental diseases were determined. Results: The prevalence of different dental diseases varies sporadically. In the present study, among the dental diseases, highest prevalence was found for dental caries (76%) followed by periodontal involvement (70%) then mesioangularly impacted teeth (2.7%) and so on. From the results, it could be interpreted that mostly radiographs are recommended for dental caries followed by periodontal status determination and rest for other diseases. Conclusion: Radiographic evaluation is an adjunct of clinical diagnosis. Diseases like Dental caries, bone loss, root stumps which cannot be visualized clinically require the radiographic evaluation necessarily. Hence, judicious utilization of radiographic procedures should be practised for the benefit of the patients.

“…Impacted teeth are teeth that are obstructed during the eruption process with the presence of gums, bones, or other teeth above them; impaction usually occurs due to lack of eruption pressure, lack of space due to the jaws that tend to be narrow to large tooth sizes, mandibular growth that is too fast and too slow, the position of the teeth in the arch or hereditary factors. 1,2 The most common tooth impaction frequency was mandibular third molar impaction.…”

“…Generally, third molars erupt at the age of 17-21 years. 1 The high prevalence of impaction in research at the Dental and Oral Hospital (RSGM) Faculty of Dentistry (FKG) UNPAD in 2014, based on observations made of 100 FKG UNPAD students, Class of 2010, it was found that the number of mandibular third molars had impacted as many as 58 people.

“…7,8 The position of impacted third molars based on Winter's classification was mesioangular, followed by vertical and horizontal, and the least was distoangular. 9,1 The impaction position with a horizontal inclination is the most dangerous because the tooth surface is in contact with the mandibular canal. 10 Meanwhile, the mesioangular impaction position was found to have a darkening of the mandibular third JHDS 2023 | 459 molar root, which indicates the proximity of the mandibular third molar root to the mandibular canal.…”

Impacted teeth are teeth obstructed during the eruption process; the high prevalence of impacted teeth, especially third molars, accompanied by complaints that arise, requires omentectomy. Winter's classification shows various positions of impacted third molars based on angulation. This classification is judged to be describe the relationship of the apical position of the mandibular third molar tooth to the mandibular canal more clearly. The odontectomy procedure requires an excellent preoperative approach to consider the structures around the mandibular third molar, one of which is the mandibular canal, because the canal's proximity to the third molar root can increase the risk of nerve injury during the odontectomy procedure. This study aims to determine the relationship between the third mandibular impaction Winter classification and the mandibular canal distance on panoramic radiographs. The samples of this study were 53 and were grouped according to the position of the impaction vertically, mesioangularly, horizontally, and distoangularly. The study was conducted cross-sectionally by measuring the apical distance of the mandibular third molar to the upper border of the canal on a panoramic radiograph using a manual caliper. The space obtained was statistically analyzed using the eta correlation test. The results showed that 38 and 48 impactions were found to have the most mesioangular impaction, followed by horizontal, vertical, and distoangular paping the least. The mesioangular position measured the distance from the apical third molar of the impacted mandible to the closest distance to the mandibular canal, followed by the horizontal and the longest distance in the vertical position. Statistical tests were conducted to determine the relationship between the mandibular third molars and the mandibular canal. In the test results, the calculated F value on tooth 38 (2.64) and tooth 48 (0.507) was smaller than the F table value (2.794); this indicates there is no significant relationship between the two variables. The absence of a close relationship between the mandibular third molar distance and the mandibular canal indicates the possible low risk of complications in paresthesia after the odontectomy procedure.
