Abramovitz I, Zakopay E, Zini A, Chweidan H, Balakirski D, Protter NE, Almoznino G. Pre-Operative Oral Health-Related Quality of Life in Patients Attending Surgical Removal of Mandibular Third Molar Teeth. Healthcare (Basel) 2021; 9:healthcare9010085. [PMID: 33467088 PMCID: PMC7830983 DOI: 10.3390/healthcare9010085] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 01/09/2021] [Accepted: 01/13/2021] [Indexed: 11/16/2022] Open
Abstract
The study aimed to measure the pre-operative oral health-related quality of life (OHRQoL) and to identify patient and teeth pathologies associated with worse OHRQoL among patients attending mandibular third molar tooth extraction. Data were collected preoperatively from 199 patients attending surgical removal of their mandibular third molar. To that end, we measured the Oral Health Impact Profile-14 (OHIP-14) and analyzed its association with: (1) demographics; (2) health-related behaviors such as smoking, alcohol consumption, physical activity, and dietary habits; (3) Plaque Index (PI); (4) Decay, Missing, and Filled Teeth (DMFT); and (5) clinical characteristics related to third molar extraction, such as the indication for extraction, tooth angulations, and radiographic pathology. The mean age of the study population was 21.5 ± 3.2 years and the mean OHIP-14 global score was 22.5 ± 8.3. The present study identified patient and teeth profiles that are associated with worse pre-operative OHRQoL in patients attending mandibular third molar extraction. The “vulnerable patient” profile includes poor health-related behaviors, particularly the performance of physical activity less than once a week (p = 0.028). The “disturbing teeth” profile includes higher plaque scores (p = 0.023) and specific characteristics of the third molar teeth, such as pericoronitis (p = 0.027) and radiolucency around third molars in panoramic radiography (p < 0.001). These findings support the hypothesis that OHRQoL is a complex phenomenon which is associated with the patient’s health-related behaviors as well as with specific tooth pathologies.

Abstract
Dentoalveolar surgeries are among the more common procedures performed by oral maxillofacial surgeons. It is only natural that there are several controversies associated with many aspects of this type of surgery. Although good scientific evidence is the basis of most oral maxillofacial procedures, some of what is accepted as common wisdom may not meet strict guidelines of evidence-based practice. This article explores some controversies that are relevant to the current practice of dentoalveolar surgery.

Abstract
PURPOSE To assess the impact of third molar removal on the periodontal status of adjacent second molars and teeth more anterior in the mouth in patients with mild symptoms of pericoronitis. PATIENTS AND METHODS Healthy patients with mild symptoms of pericoronitis affecting at least 1 mandibular third molar were recruited for a study approved by the institutional review board. The subset analyzed in this study had all 4 third molars removed. Data were collected at enrollment and at least 3 months after surgery. Full-mouth periodontal probing was conducted at 6 sites per tooth. A probing depth of at least 4 mm (PD4+) was considered an indicator for periodontal pathology. The presence of a PD4+ on the distal of second molars (D2Ms) or anterior to the D2Ms, the number of PD4+s, and extent scores (percentage of PD4+s of all possible probing sites) were assessed at the patient and jaw levels. The association between patients' pre- and postsurgical periodontal status was assessed using the McNemar exact test. The level of significance was set at .05. RESULTS The median age of the 69 patients was 21.8 years (interquartile range, 20.2 to 25.2 yr). Forty-five percent were men, and 57% were Caucasian. Significantly more patients (88%) had at least 1 D2M PD4+ at enrollment compared with after surgery (46%; P < .01). D2M extent scores decreased from 31.5 at enrollment to 11 after surgery. Significantly more patients (61%) had at least 1 PD4+ anterior to the D2M at enrollment compared with after surgery (29%; P < .01). Extent scores anterior to the D2M decreased from 2.0 at enrollment to 0.6 after surgery. CONCLUSIONS Removal of third molars in patients with mild pericoronitis symptoms improved the periodontal status of the D2Ms and teeth more anterior in the mouth.

Effect of removing an impacted mandibular third molar on the periodontal status of the mandibular second molar. J Oral Maxillofac Surg 2011; 69:2691-7. [PMID: 21864969 DOI: 10.1016/j.joms.2011.06.205] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2011] [Accepted: 06/08/2011] [Indexed: 11/24/2022]
Abstract
PURPOSE The aim of this study was to evaluate the change in the periodontal status of mandibular second molars after surgical extraction of adjacent impacted lower third molars. MATERIALS AND METHODS The study was based on a 1-year follow-up of 48 patients (20 men and 28 women) recruited consecutively after the extraction of an impacted lower third molar. Panoramic radiographs were obtained and clinical examinations were carried out at baseline to determine the periodontal status (probing depth and dental plaque and gingival indices) both for the second molar and for the 4 posterior sextants. After surgical removal of the impacted mandibular third molars, all patients were assessed at 3, 6, 9, and 12 months for changes in periodontal status. RESULTS The periodontal health of the second molar was found to improve gradually after third molar surgery in all clinical parameters. Probing depth was gradually reduced by about 0.6 mm quarterly, until a final depth of 2.6 ± 0.8 mm was attained. The relative risk of having a plaque index and gingival index coded as 0 (healthy) or 1 (minor problems) was about 10 times higher at the end of the follow-up than at baseline for both indices. The periodontal status of the 4 posterior sextants also improved gradually. Molar depth, according to the Pell and Gregory classes and types, seemed to be the main factor modulating both the baseline probing depth and the change in probing depth during follow-up. CONCLUSIONS Our results suggest that the initial periodontal breakdown established on the distal surfaces of the second molars and in the periodontal health of the 4 posterior sextants can be significantly improved 1 year after surgical removal of the ipsilateral lower third molar.

Abstract
OBJECTIVE The objective of this study was to compare the effect on periodontal health of ultrasonic versus manual scaling of the lower second molar (L2M) root surface following surgical extraction of mesioangular lower third molars (L3M). STUDY DESIGN Randomized single-blind clinical trial to compare the effectiveness of ultrasonic scaling of the L2M (experimental group) and manual scaling and root planing (control group) after surgical extraction of the corresponding L3M. RESULTS Forty-three subjects were enrolled, 69.8% completing the study. The postoperative bony defect on the distal surface of the L2M was significantly reduced for both treatment groups (P = .001). Despite a higher reduction of intrabony defect being observed in the ultrasonic group, the difference was not significant (P = .17) at 6 months. Furthermore, there was also no statistically significant correlation (P > .05) between the postoperative pocket depth and the treatment group (ultrasonic or manual). CONCLUSIONS Pocket depth and depth of the intrabony defect were similar in both experimental and control groups.

Review of flap design influence on the health of the periodontium after mandibular third molar surgery. ACTA ACUST UNITED AC 2007; 104:18-23.

Abstract
The purpose of this study is to review the effect of flap design in terms of periodontal status of the preceding second molar after lower third molar surgery. Impacted lower third molar surgery may result in periodontal complications on the distal surface of the adjacent second molar. Flap design that is used during impacted third molar surgery is important to prevent those complications. Several different flap techniques, mainly envelope, triangular (vertical) flaps, and their modifications have been developed to minimize those complications. Each technique has some advantages as well as disadvantages. It is also reported that the selection of a flap design does not seem to have a lasting effect on the health of periodontal tissue. The effect of the type of flap used for lower third molar surgery on the periodontal status of the second molar, as well as the factors that may influence this outcome, has been uncertain. The decision to use on one or the other of the flaps should be based on surgeon's preference.

Abstract
Several conflicting findings have been published in previous literature regarding the effects of impacted third molar extraction on the periodontal health of the adjacent second molar; some authors have shown improvement of periodontal health distal to the adjacent second molar, whilst others have demonstrated loss of attachment and reduction of alveolar bone height. The purpose of this controlled clinical and radiographic study is to evaluate the long-term changes in periodontal health and alveolar bone height distal to the adjacent second molar following extraction of an impacted third molar. This split-mouth design study included 25 patients who underwent extraction of one mandibular impacted third molar (test), whereas the opposite tooth remained intact (control). Pre-operative and current-state panoramic radiographs were than scanned, and alveolar bone height was digitally measured on the distal aspect of the second molar on the test and control sides. Current-state clinical measurements were performed on both sides, and consisted of plaque index, gingival index, periodontal pocket depth, gingival margin position and clinical attachment level. Student's t-test for paired observations was used in order to examine the statistical significance of the differences in clinical parameters between the test and control sides and the differences in alveolar bone height pre- and post-operatively on both sides. Extraction of an impacted third molar resulted in a significant gain of alveolar bone height on the distal aspect of the adjacent second molar on the test side, whereas slight bone loss was noted on the control side. Even though the difference in plaque index between the test and control sides approached statistical significance following extraction, all clinical parameters seem to be unchanged. Further follow-up on clinical and radiological parameters is required for a more profound understanding of the long-term effects of third molar extraction on the periodontal health of the adjacent second molar.

Abstract
Teeth may become impacted when they fail to erupt or develop into the proper functional location. As such, impacted teeth are considered nonfunctional, abnormal, and pathological. The mandibular third molar is the most common tooth to become impacted. The cause of impacted third molars is thought to be inadequate space. Several studies indicate that a change from a coarse, attritive diet to a modern, refined diet has lead to an increased incidence of impacted teeth. Interproximal attrition allows for greater mesial migration of teeth and space for third molar teeth. Teeth that fail to attain a functional position may be pathological and should be considered for removal. The indications for removing impacted teeth can be divided into those of acute or chronic pathology. Impacted third molars are often associated with pain, infection, cyst formation, benign tumors, root resorption, bone loss, periodontal disease, and caries. The decision to surgically remove impacted third molars is often unclear. There are no absolute treatment protocols established. The dentist must consider a variety of factors and make an informed decision with the patient. Most experienced clinicians combine objective data and common sense to arrive at a logical treatment plan. The purpose of this article is to discuss factors related to impacted teeth and help the orthodontist understand the general management of impacted third molars. The decision for surgery will be assisted by an understanding of all of the risk factors associated with impacted teeth and presenting the options to the patient.

Abstract
PURPOSE This prospective clinical study was designed to determine the clinical and biologic outcomes of treatment for minor signs and symptoms of pericoronitis. PATIENTS AND METHODS Patients (n = 20) with all third molars, presenting consecutively to an academic clinical center for treatment of minor signs and symptoms of pericoronitis, were enrolled in the study. At the initial visit, gingival crevicular fluid (GCF) samples to assess levels of the cytokines interleukin- 1b (IL-1b) IL-1b and prostaglandin E2 (PGE2) as a measure of the host inflammatory response, and plaque samples to identify microorganisms, were collected from the distal of all second molars and the mesial of first molars. Standardized vertical bite wing radiographs were taken to assess alveolar bone height on the distal of the second molars and the inclination and the degree of eruption of the third molar. Full-mouth periodontal probing was conducted to determine probing depths and relative clinical attachment levels (CAL). Pain levels were assessed with Gracely verbal descriptor scales for sensory intensity and unpleasantness and 10-cm visual analog scales. Symptomatic third molar sites were treated with local debridement and irrigation after baseline data collection. One week after entry, data were collected again. Subsequently, the patients were scheduled for removal of all third molars. Data collection was repeated 3 months postsurgery. As controls, data were collected from 12 subjects who had asymptomatic third molars removed previously. RESULTS At entry, symptomatic mandibular third molars (n = 21) were mostly vertical (n = 18) and at or above the occlusal plane (n = 19). No maxillary teeth had symptoms. Microbial counts were elevated for specific anaerobic microorganisms. GCF IL-1b levels were elevated at the distal of second molars adjacent to symptomatic third molars, as compared with asymptomatic third molars and second molars in control patients. Alveolar bone levels and CAL on the distal of second molars were normal. At 1 week, patients' pain symptoms and IL-1b levels were reduced, but microbial counts remained high. Three months after surgery, patients had no pain symptoms, and alveolar bone levels and CAL were similar to entry levels. IL-1b levels were elevated at both the distal of second molars and the mesial of first molars for all patients; microbial counts decreased, although not to levels of control patients. No increase in microbial counts for Porphyromonas gingivalis or Bacteroides forsythus, or GCF PGE2 levels, risk factors for progressive periodontal disease, was detected in samples taken from the study patients. CONCLUSION Pericoronitis expressed by minor signs/symptoms in these patients was associated with considerable discomfort. Symptomatic mandibular third molars were vertical and at or near the occlusal plane. Additionally, this condition was characterized by microbial flora and GCF inflammatory mediator levels that are more consistent with gingivitis than periodontitis. Removal of third molars eliminated symptoms, but the microbial burden and an affected patient's inflammatory response, as measured by IL-1b levels, remained elevated as compared with controls. Further study is needed to determine which of these factors can be used to identify patients at risk for pericoronitis before symptoms arise.
