Abstract Background To evaluate the associations of impaction patterns of mandibular third molars (M3Ms) with pathologies caused by them. Methods In this study, 262 patients with 432 impacted M3Ms were included. The pathologies include pericoronitis, mandibular second molar (M2M) caries, and M2M distal periodontal pathology. The impaction patterns of M3Ms and the pathologies were examined, and the M2Ms outcomes after the surgeries were evaluated. χ2 test was used to analyze the data and a P value of <0.05 was considered statistically significant. Results Pericoronitis was the major symptom in all patients, whereas the propensities of M2M distal caries and periodontal pathologies increased in older patients. Soft tissue impacted and vertically angulated teeth were more associated with the pericoronitis (p <0.05); Mesio-angular impacted teeth in less deep positions had greater risks of M2Ms distal caries (p <0.05); Mesio-angular and horizontal impacted teeth in relative deep positions were more likely to cause M2Ms distal periodontal pathologies (p <0.05). Conclusions Extractions of soft tissue impacted teeth in vertical angulations should be considered. While removals of mesially and horizontally angulated or bony impacted teeth could be delayed.

To evaluate the associations of impaction patterns of mandibular third molars (M3Ms) with pathologies caused by them. In this study, 262 patients with 432 impacted M3Ms who referred in Shanghai Xuhui District Center were reviewed. The pathologies include pericoronitis, mandibular second molar (M2M) caries, and M2M distal periodontal pathology. The impaction patterns of M3Ms and the pathologies were examined, while the M2M outcomes after surgeries were evaluated. A χ2 test was used to analyze the data, with a p value of <0.05 being considered statistically significant. Pericoronitis was the major symptom in all patients, whereas the propensities of M2M distal caries and periodontal pathologies increased in older patients. Soft tissue impacted and vertically angulated teeth were more associated with pericoronitis ( p < 0.05); mesio-angular impacted teeth in less deep positions had greater risks of M2Ms distal caries ( p < 0.05); mesio-angular and horizontal impacted teeth in relative deep positions were more likely to cause M2Ms distal periodontal pathologies ( p < 0.05). Extractions of soft tissue impacted teeth in vertical angulations should be considered, while removals of mesially and horizontally angulated or bony impacted teeth could be delayed.

OBJECTIVESThe aim of this study was to evaluate the relation of distal caries of second molar with patterns of impacted third molar.METHODOLOGYA retrospective study was carried out from January 2017 to June 2017.A total of 160 patients and 276 impacted teeth were selected with an age > 18 years. A single researcher assigned the diagnosis of caries and patterns of impacted teeth through clinical notes and orthopantomogram(OPG)which was reviewed by Head of Department. Winter’s and Pell and Gregory classification was used for impaction classification. The data was analyzed using SPSS 22.0 version. P ≤ 0.05 was considered as statistically significant.RESULTSFemale (56.3%) were predominant than male (43.8%) with mean age presentation was 24.2 ± 4.7 years.271 mandibular second molars were present. Vertical (64.5%) impaction was found to be the most frequent followed by mesioangular (19.6%). Pearson correlation showed that vertical impaction was significantly related to distal caries of second molar(Right side, r=.262 p=.002 and Left side, r=.240 p=.006).CONCLUSIONVertical impaction was positively related with distal caries therefore prophylactic removal of lower impacted teeth is recommended.

ABSTRACT Objectives: To investigate factors associated with spontaneous mesialization of impacted third molars after second molar protraction to close the space caused by a missing mandibular first molar (L-6) or retained deciduous mandibular second molars with a missing succedaneous premolar (L-E). Materials and Methods: Panoramic radiographs of patients treated with mandibular second molar protraction to close the space due to missing L-6 or L-E (14 males, 36 females, mean age = 18.6 ± 4.4 years) were analyzed before treatment (T1) and after second molar protraction (T2). Factors associated with the amount of third molar mesialization were investigated using regression analyses. Results: Mandibular second molars were protracted by 5.1 ± 2.1 mm and 5.8 ± 2.7 mm, measured at the crown and root furcation, respectively. After second molar protraction, third molars showed spontaneous mesialization by 4.3 ± 1.6 mm and 3.8 ± 2.6 mm, measured at the crown and root furcation, respectively. Nolla's stage of the third molar at T1 (B = 0.20, P = .026) and second molar protraction time (B = 0.04, P = .042) were significantly associated with the amount of third molar mesialization. Conclusions: Greater third molar mesialization was observed when Nolla's stage of the third molar was higher before treatment and when the second molar protraction time was longer.

Aim: To analyse early recognition of the distal cervical caries of mandibular second molar caused by impacted mandibular third molar, to correlate oral health and caries status and to find out the average age groups and gender affected by impacted third molar Methods: A cross-sectional survey of 300 participants was conducted over a 15-month period at Rehmat Memorial Hospital, Abbottabad. 300 participants having impacted third molar having distal cervical caries in mandibular second molar were analyzed clinically and radiographically. Data was analyzed using SPSS version 23.0 Results: the demographic data of 300 patients with impacted mandibular third molars were analyzed. 64% were male and 36% female that have extractions due to impaction. Caries caused in more than half of participants by mesioangular impaction, which was 52%, 3% due to distoangular, 26% due to distal, and 18% due to horizontal impaction. In 63.25% of cases, teeth were lost due to caries, periodontitis caused 20.25% of tooth loss, pericoronitis 7.75%, orthodontics 3.75%, prosthodontics 1.2%, trauma 1%, and other factors were 2.5%. study reveals that 30.5 % of the extractions were done from 21 and 30 years and 23 %of extractions were performed. 40% of those who took part in the study did not brush their teeth. Socioeconomic status also has a great impact on tooth extractions. Conclusion: After conducting this study, it was concluded that there was a relationship between the prevalence of distal cervical caries in mandibular second molars and the placement of neighbouring impacted mandibular third molars. As a result, the extraction of mandibular third molars should be done to avoid cavities and premature tooth loss in the neighboring molar. Key words: Third molar impaction, distoangular, distal cervical caries, extraction, 2nd molar caries

Objectives: To determine the effectiveness of tube drain compared with conventional suturing on postoperative complications after extraction of impacted mandibular third molars. Study Design: Cross Sectional study (Comparative). Setting: Department of Oral & Maxillofacial Surgery, Institute of Dentistry, LUMHS Jamshoro/Hyderabad. Period: Six months duration from 12-11-2015 to 13-05-2016. Material & Methods: All the patient age from 18 to 45 years irrespective of gender, having mesioangular impacted mandibular third molar were included in the study. Patients were divided into two groups, Group-A and group-B. The severity of pain was recorded by using Visual Analog Scale from 0 no pain to 10 worst pain, degree of swelling was measured by facial size through Amin and Laskin criteria and mouth opening was measured by interincisal distance through ruler. All data was recorded on the 3rd and 7th day by the clinician. Results: Mean age of group A was 31.22+7.21 years, and mean age of group B was 28.34+5.33 years. Male were found slightly more as compared to female. On 3rd day the post-operative pain assessment was almost equal in both groups p-value 0.06 and assessment of post-operative swelling on 3rd day was found with insignificant difference p-value 0.22. Assessment of pain on 7th post-operative day was that the severe pain was found significantly reduced in group B as compared to group A p-value 0.01, swelling was significantly reduced in group B p-value 0.04. While mouth opening was also found significantly more in group B as compared to group A p-value 0.022. Conclusion: After removal of impacted mandibular third molars, incorporating tube drain is very effective as compared to conventional suturing in reducing the facial swelling, trismus and postoperative pain.

Abstract: Third molar development is a concern in dental care because of its influence on stomatognathic system. Due to third molar irregular pattern of eruption, different clinical and radiographic considerations on how to decide an extraction were studied. This study was aimed to evaluate the effect of mandibular third molar mesial angulation (MA) towards the extractions on panoramic radiographs. This was a retrospective study. A longitudinal study of mandibular third molars (n=192) of 102 individuals (50 Female and 52 Male) was conducted. Development of the mandibular third molar was staged according to modified Köhler et al. staging technique. Mesial angulation was measured from the intersection between axes of third molar and adjacent second molar of the most developed stage for extraction cases or before root completion for non-extraction cases. Of 102 subjects, 107 mandibular third molars were extracted. The increase of 1° of MA would increase the odds ratio (OR) of extraction by 1.113 (95% CI 1.070-1.158, p<0.01). The ROC curve showed the MA of 18.5o as the threshold of extraction with 76% of sensitivity and 68% of specificity. In conclusion, MA has the possibility as a predictive factor of mandibular third molar extraction. Future studies using bigger sample sizes and variations of third molar development are suggestedKeywords: third molar, angulation, extraction, predictive factor, panoramic radiographs Abstrak: Pertumbuhan molar ketiga menjadi perhatian pada perawatan dental karena pengaruh-nya pada sistem stomatognasi. Terdapat banyak penelitian tentang berbagai pertimbangan klinis dan radiografis untuk melakukan ekstraksi molar ketiga karena pola erupsinya yang tidak menentu. Penelitian ini bertujuan untuk mengevaluasi efek angulasi mesial (AM) dari molar ketiga rahang bawah terhadap tindakan ekstraksi pada radiografi panoramik. Jenis penelitian ialah retrospektif. Pengamatan molar ketiga rahang bawah (n=192) secara longitudinal dilakukan pada 102 individu (50 perempuan dan 52 laki-laki). Pertumbuhan molar ketiga diukur berdasarkan tahap pertumbuhan dari teknik modifikasi Köhler et al. AM diukur dari pertemuan aksis molar ketiga dan molar kedua di sebelahnya, pada tahap pertumbuhan paling akhir pada kasus ekstraksi, atau sebelum akar gigi terbentuk sempurna pada kasus non-ekstraksi. Pada sampel penelitian, ekstraksi dilakukan pada 104 molar ketiga rahang bawah. Peningkatan 1o dari AM akan meningkatkan rasio peluang dari ekstraksi sebesar 1,113 (95% CI 1,070-1,158, p<0,01). Pada kurva ROC, AM sebesar 18,5o menunjukan 76% sensitivitas dan 68% spesifisitas. Simpulan penelitian ini ialah AM dapat digunakan sebagai faktor prediksi terhadap ekstraksi molar ketiga rahang bawah. Perkembangan penelitian selajutnya dapat dilakukan dengan jumlah sampel yang lebih besar dan dengan memperhatikan pertimbahan klinis serta parameter radiografik lainnya.Kata kunci: molar ketiga, angulasi, ekstraksi, faktor prediksi, radiografi panoramik

Abstract Objective: To test the hypothesis that there is a relationship between forward mandibular third molar migration and root curvature of the mandibular third molars. Materials and Methods: The study is comprised of 64 patients who had a history of unilateral mandibular first molar extraction before 16 years of age with no other missing teeth or prosthetic restorations in the mandible. The extraction space was fully or partly closed. The mean remaining space was 1.1 ± 0.41 mm. The root angles for the mesial and distal roots of the mandibular third molars were measured on the panoramic radiographs by calculating the differences between the angle formed by the long axis drawn perpendicular to the occlusal plane of the crown of mandibular third molar and the central line of the lower one ninth of the root through the root apex. The differences between the extracted and nonextracted sides for mesial and distal roots were analyzed using a paired sample t-test. Results: Both mesial and distal roots were approximately 8° more vertical on the extraction sides than on the nonextraction sides. The differences were statistically significant. Conclusion: Mesial tooth migration of mandibular third molars reduces the amount of root curvature developing on this tooth.
