Impact of mandibular third molar extraction in the second molar periodontal status: A prospective study

Abstract

Aim:The aim of the present study was to assess the periodontal condition and sensitivity of second mandibular molars after the extraction of the adjacent third molar, while also assessing the quality of life of the patients.Materials and Methods:Twenty-three healthy patients were assessed in terms of probing depth, gingival height, gingival thickness, dental sensitivity, plaque index and bleeding on probing (adjacent second mandibular molar), before the surgical procedure, as well as 60 and 180 days after the surgery. The following data were also recorded and measured: the position and size of the impacted teeth; the size of the alveoli after surgery and the quality of life of the patient.Results:Significant differences were found for probing depth and gingival height before and after 180 days. The plaque index increased significantly after surgery (P = 0.004), as did bleeding on probing. No significant difference was found for the quality of life. The size of the third molar extracted was correlated with bleeding on probing 180 days after the surgery.Conclusion:An improvement was noted in the periodontal condition of the second mandibular molars after the extraction, based on the assessments of probing depth and gingival height. The position of the third molar affected the periodontal condition of the second mandibular molar. No alterations were recorded for dental sensitivity or the quality of life after the extraction.

Pre-Operative Oral Health-Related Quality of Life in Patients Attending Surgical Removal of Mandibular Third Molar Teeth

“…Third molar pathology and pericoronitis may cause pain and discomfort and interfere with eating, and this may explain their association with worse OHRQoL. Indeed, previous studies demonstrated that impacted third molars may increase a predisposition towards pericoronitis, orofacial infections, dental caries, as well as periodontitis [ 39 , 40 , 41 ]. In line with our findings, previous studies also demonstrated that clinically important correlations existed between pericoronitis pain and lifestyle and oral function, associations which are not often considered by clinicians or policy makers [ 42 ].…”

Surgical extraction of the impacted mandibular third molar: Vestibular bone window technique

“…It depends on the patient's age, third molar impaction type and depth, and pre-surgical periodontal defects. [5] However, there are no clear scientific data to explain the outcome of third molar surgical extraction on M2M periodontal status [6][7][8]. It is also unclear how the flap design [9][10][11] or suturing technique [12] will alter the results.…”

Effects of Impacted Lower Third Molar Extraction on Periodontal Tissue of the Adjacent Second Molar

“…In addition, for the lower ILTM, conventional minimally invasive tooth extraction surgery may still result in bone loss and periodontal pockets formation in the distal second molar. 39 Therefore, scholars designed ultrasonic osteotome window: using ultrasonic osteotome to open a window on the mandibular buccal bone plate, removing tooth, and resetting bone fragments. 40 The extraction socket formes a closed space that effectively isolates the growth of epithelial cells to benefit bone tissue regeneration 41 and shortens the healing time.…”
