The Influence of Mandibular Third Molar Position on Distal Caries in Mandibular Second Molar
Introduction: Distal caries of mandibular second molars has been documented to be associated almost exclusively with impacted third molars. The level of involvement of second molars in distal caries is influenced by the angulation of the occlusal surface of mandibular third molars and third molars depth. In spite of the importance of these factors on the occurrence of distal caries, their influence on prophylactic extraction decision of asymptomatic impacted molars for Iraqi population did not get enough attention. Aim: of the study: To determine the influence of mandibular third molar impaction, as identified by panoramic radiograph, on distal caries incidence in second molar in Iraqi population. Materials and Methods: Panoramic radiographs of impacted mandibular third molars prior to surgical extraction were retrieved from the database of Al-Karamah Secondary Dental Care Centre in the period 2004-2013. Demographic data were collected for all cases. Each panoramic radiograph was examined for the presence of distal caries of mandibular second molar and for the level of depth and degree of angulation of adjacent impacted mandibular third molar. Results: One hundred forty-eight panoramic radiographs of 214 pre-surgically extracted impacted mandibular third molars were reviewed. Eighty-four (56.8%) of the cases were for males and sixty-four (43.2%) were for females. Chi-Square Test showed significant relationship between age group, impaction angulation, impaction depth and incidence of mandibular second molar distal caries. It also showed highly significant relationship between angulation and depth of impaction. Conclusion: Horizontally impacted mandibular third molars close to the level of occlusion increases the chance of distal caries incidence in adjacent mandibular second molars. Close monitoring for such cases would be a suitable option. Further prospective studies should be conducted to study the influence of other factors on distal caries incidence.

To identify risk factor of distal surface caries on mandibular second molar associated with partially erupted mandibular third molar. Setting: The study was conducted in the Department of Oral and Maxillofacial Surgery, Liaquat University Hospital Jamshoro/Hyderabad from April 2013 to September2013. Methodology: Total 273 patients of either gender with age 16-45 years had partially impacted mandibular third molar, were included. Diagnosis was made on clinical as well as periapical view and OPG examination. Distance from CEJ of mesial surface of third molar to CEJ of distal surface of second molar was measured in millimeters. Results: Results about association of caries with other variables showed that significant association of caries was observed with gender, winter classification, Pell Gregory (ramus), and angulation with p<0.01. The association of caries was also observed with age and third molar site with p<0.05. The association was not significant with Pell Gregory (occlusal) and distance with p> 0.05. Conclusion: It was concluded with the results of this study that there was an increased risk of developing dental caries in 2 nd molar tooth at distal surface with risk factor being partially erupted mandibular 3rd molar, mesioangular, class I, level A, and angulation of more than 30 degrees.

The purpose of this study was to analyze the correlation parameters between the distal caries of the mandibular second molars (M2Ms) and the eruption status of the mandibular third molars (M3Ms). Study design. The records of 786 patients who had their M3Ms extracted from 2002 to 2007 at Samsung Medical Center were reviewed. The distal caries of M2Ms, age, gender, angulations, impaction degree, and distance between M2M and M3M were assessed. Results. Among 883 M2Ms, 152 had distal caries (17.2%, caries group). In the caries group, 79.6% of M3Ms exhibited mesial angulation between 40°and 80°and 82.2% of M3Ms exhibited an impaction level in which the most coronal aspect of the M3M was located superior to the occlusal surface of the M2M. The distance between M2M and M3M (between cemontoenamel junctions) was 7-9 mm for 57.2% of the caries group. Conclusions. The M3Ms under eruption status as described here could be considered for preventive extraction.

Third lower molar partially erupted is commonly encountered in dental practice. This situation challenges clinicians with the dilemma whether to remove or to monitor it, because this molar can cause pathology of the adjacent second molar. The aim of this retrospective study is to evaluate the relationship between third mandibular molar and distal cervical caries in second molar. This retrospective study analyzed 55 digital orthopantograms of adult patients and a total number of 95 mandibular third molars were assessed for eruption status, angulation, radiographic evidence of caries or restoration in the mandibular third molar, and radiographic evidence of caries or restoration in the distal surface of the mandibular second molar. The distal cervical caries in second molar is associated with fully erupted and partially erupted wisdom molar in horizontal, mesioangular and vertical position and less with presence of caries in third molar. There are caries lesions in distal second molar...

Background: Removal of impacted third molars is the most common oral surgical procedure. Many investigators have questioned the necessity of removal in patients who are free of symptoms or associated pathologies. Aim: The aim of this retrospective study was to evaluate the incidence of caries on distal aspect of mandibular second molars in patients referred for corresponding third molar assessment and to identify its association with angular position and depth of the impacted mandibular third molars based on the classification of Pell and Gregory. Methodology: Records of 150 patients with impacted third molar presenting to the Department of Oral and Maxillofacial Surgery, Sri Rajiv Gandhi College of Dental Sciences and Hospital, were assessed retrospectively. The radiographic angulation and depth of mandibular third molar impaction were determined and compared to determine the relationship with incidence of caries on the distal surface of the second molar. Results: According to this study results, 37.5% cases show caries on the distal aspect of mandibular second molars. The incidence of caries with mesioangular impacted third molars was 55%. A majority of these mesioangular cases were Level B and Class I as per the Pell and Gregory classification. Conclusion: The prophylactic extraction of mandibular third molars is indicated if the angulation is between 30° and 70° and is justified by incidence of distal caries in the second molars.

Objective: The purpose of this study was to examine the relationship between the degree of mesioangular mandibular third molar teeth and the presence of distal caries in the second molar teeth. Materials and Methods: In this retrospective study, panoramic radiographs of 617 patients (328 females, 289 males) with impacted teeth in partially erupted mesioangular position were examined. The angle between the mandibular occlusal plane and the occlusal surface of the mandibular third molar was measured. Third molar teeth in mesioangular positions with an angle between 11° and 30° were classified as Group 1, an angle between 31° and 50° as Group 2, and an angle between 51° and 70° as Group 3. For each group, the presence of caries in the distal contact point of adjacent second molar teeth was detected. Results: A total of 816 mandibular third molar teeth in the mesioangular position were analyzed. Of these, 439 (53.8%) were in females and 377 (46.2%) were in males. The prevalence of caries in the distal aspect of the second molar teeth was 34.5% in males and 21.4% in females (p<0.001). A statistically significant difference was found between the groups (p<0.05). The results showed that a slope of 51° to 70° in mandibular third molar presents a higher risk for caries formation in the distal aspect of second molar teeth. Conclusions: Early prophylactic extraction of impacted mandibular teeth with a slope between 51° and 70° may prevent caries formation in the distal aspect of adjacent second molar teeth.

Background: This study is aimed to determine the prevalence of impacted third molars and to investigate the effects of their eruption level and angulation on caries formation in the distal of the adjacent tooth. Material and Methods: This cross-sectional study was conducted on panoramic radiographs of 38481 patients who were admitted to the Trakya University, Faculty of Dentistry. The panoramic radiographs of 7998 patients with at least one impacted third molar were included. Third molars were classified according to Winter's classification and Pell and Gregory's classification. The frequency of caries in partially impacted third molars and adjacent second molars was determined. The chi-square tests were used to determine potential associations between the third molars' level of eruption, angulation, and caries development. Results: The study group consisted of 4423 females (55.3%) and 3575 males (44.7%) with a mean age of 36.3±13.4 years. The prevalence of the third molar impaction rate was 23%. The impaction pattern of partially erupted third molars was characterized by an eruption level of A with the vertical position in both jaws. Partially erupted and vertically placed maxillary third molars in the level of position A caused more caries in the adjacent tooth and mesioangularly located partially erupted mandibular third molars were associated with more caries in the adjacent tooth. Conclusions: The angulation and eruption level of partially erupted third molars should be carefully examined. The prophylactic extraction of vertically and mesioangularly located third molars, especially with an eruption level of position A can be suggested to eliminate the related complications and risk of caries.

Objective. The objective was to determine the association between commonly found pathologic conditions and angulations and impaction depths of lower third molar teeth. Study design. In this retrospective study 1,914 panoramic radiographs with 3,050 impacted lower third molars (ILTMs) were examined. Results. The problems and the prevalence evaluated were caries on mandibular second molar (12.6%), caries on ILTM (5.3%), bone loss at the distal aspect of ILTM (9.7%), and periodontal tissue damage on adjacent tooth (8.9%). A total of 26.5% of all the cases were affected by any one of the 4 pathologic changes. It was determined that horizontal and mesioangular ILTMs had high risk of caries development on second or third molar; in contrast, vertical and distoangular ILTMs had low risk. Distoangular and vertical ILTMs had high risk of development of bone loss at the distal aspect. Mesioangular and horizontal ILTMs had a high risk for periodontal tissue damage on an adjacent tooth. When evaluating impaction depth of the ILTM, class A had a higher risk of pathology than class B or C. Conclusions. Horizontal and mesioangular impactions were found with more pathologic situations; especially in class A impaction depth. Angulation and impaction depth of the ILTM should be taken into consideration when making a decision whether to extract an ILTM or not.

Investigators have different ideas about whether or not the third molars should be extracted as a preventive measure. The aim of this study is to evaluate the relationship of impacted third molar with the frequency of caries on the distal surface of the second molar. In this prospectively designed study, oral and orthopantomographic examinations of 438 patients were performed. All of the second and third molars on the mandible are classi cated by the eruption levels and angulation degrees. The presence of caries on the distal surface of the second molars was determined with the help of ICDAS-II criteria. Pearson Chi-Square and McNemar test was used to compare categorical variables and both segments. The participants in the study ranged in age from 18 to 62, with a mean age of 28.33 ± 9.2 years. While a total of 1752 teeth were examined and both segments were evaluated for angulation type and level of eruption. The most frequent angulation type was vertical, and the most frequent eruption level was A. Mesioangulatiın was the most common type of angulation associated with caries in adjacent teeth.There was a statistically signi cant variation in the prevalence of caries between the two segments (p < 0.001; χ 2 = 0.241). More caries was seen in adjacent teeth with vertical on the right segment and mesioangulation on the left. Prophylactic extraction of third molars should be considered comprehensively. The fact that different types of angulation increase caries susceptibility in both segments highlights the need to evaluate all caries development factors concurrently.
