“…Because some reports highlighted the possibility that age could influence socket healing, age was studied as a predictor of healing not only in a linear way (see above) but also was used as a variable to divide the studied sample in two. [22][23][24][25][26][27][28][30][31][32] The study sample was divided into two age groups: younger than 25, and older than 25, following Kugelberg et al 20 who suggested that individuals younger than 20 years old and older than 30 have different periodontal healing potential. Sample size was calculated to be 64 according to the sample for proportion formula, estimating that at least 20% of subjects with a PPD equal or greater than 4 mm would have a PPD, 6 months after surgery, lower than 4mm, with a precision level setting at 0.07.…”

Background The periodontal health distal of second molars (M2) is often compromised because of third molar (M3) impactions. The aim of this study was to evaluate healing and periodontal status of mandibular M2 after M3 surgical extraction. Methods Eighty‐nine consecutive patients with 89 asymptomatic M3 who needed surgical extraction of one fully‐ or semi‐impacted M3 entered this study. Clinical measurements, probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), and bleeding on probing (BOP), were compared for M2 at baseline (T0) and 6‐months (T1) postsurgical extraction. Multiple logistic regression analysis assessed different risk factors for postoperative changes of periodontal parameters. Results Six‐month M2 PPD improved at disto‐vestibular (T0‐5.2/T1‐3.0 mm) and disto‐lingual (T0‐5.4/T1‐3.2 mm) sites. The average attachment gains at T1 were 1.9 and 2 mm, respectively (P < 0.05). BOP, PI, and GI showed significant clinical improvements after extractions. Fifty‐three out of 72 (73.6%) M2 presenting a PPD ≥ 4mm at baseline healed at 6 months recall without periodontal pockets. Older age (mean 55 years, SD 16.7; range 26 to 81) and mean distal PPD at baseline of 7 mm was more likely to be associated with PPD ≥ 4 mm 6 months postextraction (P < 0.05). Past history of periodontitis patients were 41 times more likely to present PPD ≥ 4 mm after healing (OR = 41.4; 95% CI = 10.9 to 156.5, P < 0.05). Conclusion Mandibular M3 extractions seem to improve overall periodontal health distal of M2. History of periodontitis, preoperative deep pockets and older age are independent risk factors for poorer healing and residual pockets after M3 surgical extraction.

“…The average lifespan is expected to increase by another 10 years by 2050 6. Early removal of abnormal third molars could reduce the increased risk for complications in older patients 7. Since the introduction of the NICE guidelines, the average age has increased for third molar surgery, and surgery was less likely to be associated with impaction, and increasingly associated with other pathologies such as dental caries or pericoronitis 8.…”

PurposeThe purpose of this study was to determine the prevalence of missing and impacted third molars in people aged 25 years and above.Materials and MethodsThe study sample of 3,799 patients was chosen randomly from patients who visited Pusan National University Dental Hospital and had panoramic radiographs taken. The data collected included presence and impaction state, angulation, and depth of impaction of third molars, and radiographically detected lesions of third molars and adjacent second molars.ResultsA greater percentage of men than women retained at least one third molar. The incidence of third molars decreased with increasing age. The incidence of partially impacted third molars greatly declined after the age of 30. Vertically impacted maxillary third molars and horizontally impacted mandibular third molars were most frequent in all age groups. Among the maxillary third molars, those impacted below the cervical line of the second molar were most frequent in all age groups, and among the mandibular third molars, deeply impacted third molars were most frequent in those aged over 40. Dental caries was the most common radiographic lesion of the third molars. Mesioangularly impacted third molars showed radiographic lesions in 13 (9.5%) adjacent maxillary second molars and 117 (27.4%) mandibular second molars.ConclusionThe number of remaining third molars decreased and the percentage of Class C depth increased with age. Caries was the most frequent lesion in third molars. Partially impacted mesioangular third molars showed a high incidence of caries or periodontal bone loss of the adjacent second molar. Regular oral examination will be essential to keep asymptomatic third molars in good health.

“…3 Open extraction of impacted third molars by is one of the repeatedly performed procedure in oral and maxillofacial surgery. 4,5 Numerous factors are responsible for mandibular third molar impaction, which includes deficient space in dental arch, unfavourable path of eruption, density of overlying hard and soft tissues, and the late eruption sequence 6 . Occasionally orthodontic, prosthodontic, restorative and prophylactic consideration can justify the removal.…”

“…9 Distal caries in the second molar requires a restorative and endodontic management like RCT to preserve the second molar in addition to the removal of third molar, at times extraction of the 2nd molar is also indicated, i.e when the carious lesion is too large to be restored. 5,7 Preventive extraction of the mandibular third molars can be recommended as a treatment method for improving the prognosis of mandibular second molars. 9,13 Recently there are some guidelines which have been published for the management of mandibular third molars.…”

ABSTRACT… Objectives: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. Key words:Risk Factor, Distal Surface Caries, Mandibular Second Molar, Partially Erupted Mandibular Third Molar. Article Citation: Shams S, Hassan SG, Punjabi SK, Abdullah S.
