Abstract
Mandibular third molars are appeared to be the most common congenitally impacted teeth the fact that may cause many problems in different fields of dentistry. surgical removal of the impacted tooth seems to be the only solution for these problems. An important complication to address is the risk of developing periodontal breakdown ( loss of attachment) and deep periodontal pocket on the distal aspect of the adjacent mandibular second molar after surgical removal of third molar. The aim of the present study is to evaluate and compare the effect of 4 suturing techniques: (Simple loop , Figure 8 suture, Anchor suture and Closed anchor suture) on the periodontal health status on the distal aspect of the adjacent mandibular second molar after surgical removal of lower impacted third molar.Forty patients having fully impacted mandibular third molars were enrolled in this study and divided to 4 groups (Group A: Simple loop , Group B: Figure 8 suture, Group C: Anchor suture and Group D: Closed anchor suture), each group consisted of 10 patients. Surgical extraction of impacted third molars were carried out for them. Probing pocket depth (PPD) and clinical attachment level (CAL) were recorded preoperatively and 6 months after surgery. On 6 months after surgery the mean values of PPD and CAL were significantly increased on the distal surface of the adjacent mandibular second molar in simple loop & figure 8 techniques. On the other hand, no significant difference has been noticed between anchor & closed anchor techniques in comparison with preoperative values. After 6-months, PPD and CAL values of were significantly higher in thesimple loop and figure 8 techniques compared to anchor andclosed anchor techniques. The present study concluded that closedanchor suture & anchor suture techniques are preferable to closethe flaps in surgical removal of impacted mandibular third molarsto maintain a good health status on the distal side of the adjacentmandibular second molar.
