Osseous Defects

Mandibular third molar (M3) surgical extraction may cause periodontal complications on the distal aspect of the root of the adjacent mandibular second molar (M2). Patients older than 26 years with periodontal pathology on the distal surface of the M2 and a horizontal/mesioangular impacted M3 may benefit from bone regenerative therapy at the time of surgery. In this prospective case series, an alloplastic fully resorbable bone grafting material, consisting of beta-tricalcium phosphate (β-TCP) and calcium sulfate (CS), was used for the treatment of the osseous defects after the removal of horizontal or mesioangular M3s in 4 patients older than 26 years. On presentation, the main radiological finding in all patients, indicating periodontal pathology, was the absence of bone between the crown of the M3 and the distal surface of the root of the M2. To evaluate the treatment outcome, bone gain (BG) was assessed by recording the amount of bone defect (BD) at the time of surgical removal (T0) and at the time of final follow-up (T1) 1 or 2 years post-operatively. The healing in all cases was uneventful, with no complications associated with the use of the alloplastic grafting material. Clinical and radiological examination at T1 revealed that all extraction sites were adequately restored, with significant BG of 6.07 ± 0.28 mm. No residual pathological pockets on the distal surface of the M2 were detected. Pocket depth (PD) at T1 was 2 ± 0.71 mm. Within the limitations of this case series, the results suggest that β-TCP/CS can support new bone formation at M3 post-extraction sites where bone regeneration methods are indicated, thus reducing the risk of having persistent or developing new periodontal problems at the adjacent M2.

Flap Design

The aim of the study was to assess the influence of flap designs (Envelope flap (EF) and Szmyd flap (SF)) for impacted mandibular third molar extraction, on periodontal pocket depth (PPD), clinical attachment loss (CAL) and bone levels (BL) of second molar. Sixty patients indicated for third molar extractions with healthy second molars were allocated into two groups: EF and SF (n = 30). Third molars were assessed for angulation, root patterns, depth of impactions and relation with ramus (Pell and Gregory classification). Extraction of third molars was performed and PPD, CAL and BL around second molars at 0, 3 and 6 month (mon) follow-ups (FU) were assessed clinically and radiographically. ANOVA, Chi-square and Fisher’s exact test were employed to compare periodontal factors between EF and SF groups, considering p ≤ 0.05 as significant. Sixty participants with a mean age of 23.22 ± 3.17 were included in the study. Based on angulation, the most common impaction in the EF and SF groups was mesio-angular (EF, 50%; SF, 36.7%). Buccal and distal PPD showed a significant increase (p < 0.001) in both EF and SF patients from baseline to 6 mon. EF patients showed significantly higher distal and buccal CAL (6.67 ± 0.18 mm; 6.91 ± 0.17 mm) and BL (7.64 ± 0.16 mm; 7.90 ± 0.15 mm) as compared to SF patients (CAL, 6.76 ± 0.26 mm; 6.91 ± 0.17 mm-BL, 7.42 ± 0.38 mm; 7.34 ± 0.34 mm) at 6 mon FU. SF showed better soft tissue attachment (PPD and CAL) and bone stability (less bone loss) around second molars compared to EF after third molar extractions regardless of the patient, tooth and operator factors.

Introduction: Impacted third molars are a major cause of visit to the oral surgeon and are associated with various complications like pain, inflammation of associated soft tissue and trismus leading to a need for their surgical removal. They are widely classified on the basis of angulation, depth and position as evident from orthopantomogram however they present in a diverse panorama of patterns each presenting different level of difficulty and different techniques for their removal. Our study describes different pattern of impacted lower third molars and perform brief literature review of dental and skeletal implications of impacted third molars. Materials & Method: A retrospective study was designed in which 401 orthopantomogram were examined and the sex of patient, side of impaction and winters angulation based classification, depth and position classification as given by Pell and Gregory were recorded. Descriptive data analysis was performed with SPSS version 24 software. Result: Out of total number of impactions 191(47.6%) were in females and 210(52.4%) were in males. Right sided impaction was seen in 199(49.6%) cases and 202(50.4%) were seen on left side. Mesioangular impaction was most common 203(50.6%) followed by distoangular 97(24.2%), horizontal 51(12.7%) and vertical 17(4.2%). Most common depth level of impaction was level I with 203(50.6%) followed by level II 178(44.4%) and level III 20(5%). Most common position was position B 355(88.5%) followed by position A 43(10.7%) and position C 3(0.7%). The most common pattern was IB (n=170) and IIB (n=166). Conclusion: The most common impaction is mesioangular followed by distoangular and horizontal. Most of the impacted third molars are in moderately difficult position.
