Mandibular Third Molars

The objective of this study was to study the incidence of type of impaction of mandibular third molars based on the classifications of Pell and Gregory and Winter, which included angulation of the tooth and level of the occlusal surface of the third molar with respect to the second molar, respectively, in a sample of Saudi population in central region. In this retrospective study, orthopantomograms (OPGs) of 17760 patients were examined, who were reported by the Dental University Hospital (DUH) at King Saud University, Riyadh, Saudi Arabia, between the years 2016 and 2020. Out of 17760 radiographs, 2187 (12.31%) patients presented with at least one impacted third molar. Out of which, 1337 (7.52%) patients had bilateral impaction and 850 (4.78%) patients had unilateral impaction ( p < 0.001 ). No gender predominance was noted in the impaction status ( p > 0.05 ). In bilateral impaction, 671 were male (50.2%) and 666 were female (49.8%). Among unilateral impaction, 394 (46.4%) were male and 456 (53.6%) were female. Mesioangular angulation was the most common pattern of impaction (65%) followed by vertical angulation in both bilateral and unilateral impactions. Level A impaction was found to be highest in both bilateral and unilateral impactions which are 48.02% and 54.0%, respectively ( p < 0.05 ). Our study highlights mesioangular impaction and level “A” as the most frequently encountered angulation and level of impaction in impacted teeth. This study result provides us useful data regarding the radiographic status of mandibular third molars in the population of Saudi Arabia.

Abstract Background To evaluate the associations of impaction patterns of mandibular third molars (M3Ms) with pathologies caused by them. Methods In this study, 262 patients with 432 impacted M3Ms were included. The pathologies include pericoronitis, mandibular second molar (M2M) caries, and M2M distal periodontal pathology. The impaction patterns of M3Ms and the pathologies were examined, and the M2Ms outcomes after the surgeries were evaluated. χ2 test was used to analyze the data and a P value of <0.05 was considered statistically significant. Results Pericoronitis was the major symptom in all patients, whereas the propensities of M2M distal caries and periodontal pathologies increased in older patients. Soft tissue impacted and vertically angulated teeth were more associated with the pericoronitis (p <0.05); Mesio-angular impacted teeth in less deep positions had greater risks of M2Ms distal caries (p <0.05); Mesio-angular and horizontal impacted teeth in relative deep positions were more likely to cause M2Ms distal periodontal pathologies (p <0.05). Conclusions Extractions of soft tissue impacted teeth in vertical angulations should be considered. While removals of mesially and horizontally angulated or bony impacted teeth could be delayed.

The aim of this study was to compare the post-operative sequelae of removal of impacted third molars in participants treated with conventional flap elevation technique or with a minimally invasive flapless technique. Participants with bilaterally impacted mandibular third molars were included. They were divided into two sites constituting 2 groups. One group was operated by using conventional flap design and elevation and other with flapless technique. Objective clinical parameters were recorded and compared in the post-operative period like mouth opening, swelling, surgical time, and pocket depth. Subjective parameters including pain were also assessed and statistically analyzed. The sites operated in Group II (Flapless technique) had better results (p≤0.05) in terms of pain, swelling, trismus, and pocket depth distal to second molar when compared to Group I (Flap). The flapless technique gives better surgical results and improved healing process after third molar removal and so should be recommended in routine clinical practice.

ABSTRACT Objectives: To investigate factors associated with spontaneous mesialization of impacted third molars after second molar protraction to close the space caused by a missing mandibular first molar (L-6) or retained deciduous mandibular second molars with a missing succedaneous premolar (L-E). Materials and Methods: Panoramic radiographs of patients treated with mandibular second molar protraction to close the space due to missing L-6 or L-E (14 males, 36 females, mean age = 18.6 ± 4.4 years) were analyzed before treatment (T1) and after second molar protraction (T2). Factors associated with the amount of third molar mesialization were investigated using regression analyses. Results: Mandibular second molars were protracted by 5.1 ± 2.1 mm and 5.8 ± 2.7 mm, measured at the crown and root furcation, respectively. After second molar protraction, third molars showed spontaneous mesialization by 4.3 ± 1.6 mm and 3.8 ± 2.6 mm, measured at the crown and root furcation, respectively. Nolla's stage of the third molar at T1 (B = 0.20, P = .026) and second molar protraction time (B = 0.04, P = .042) were significantly associated with the amount of third molar mesialization. Conclusions: Greater third molar mesialization was observed when Nolla's stage of the third molar was higher before treatment and when the second molar protraction time was longer.

ABSTRACT Objective:  To investigate (1) whether vertical eruption of impacted third molars improves after mesialization of second molars and (2) what factors affect the vertical eruption of impacted third molars when space caused by missing molars is successfully closed by mesialization of the second molar using miniscrews. Materials and Methods:  The treatment group (Group 1) included 52 patients who had (1) missing mandibular first molars (ML-6) or missing deciduous mandibular second molars (ML-E), (2) initially impacted mandibular third molars, and (3) successful space closure of the edentulous area with orthodontics. Panoramic radiographs at start of treatment (T1) and at time of space closure (T2) were collected. The control group (Group 2) included 46 nonedentulous patients with impacted mandibular third molars without molar protraction treatment. Panoramic radiographs with similar T1/T2 treatment times were selected. Nine measurements were obtained regarding horizontal available space, vertical eruption, and third molar angulation. Results:  Third molars erupted vertically an average of 2.54 mm in Group 1 compared with 0.41 mm in Group 2. Age, gender, Nolla stage, and angle of the third molars did not show significant correlations with the vertical change of the impacted third molars, whereas the depth of third molar impaction and available space showed significant correlations. Conclusions:  Impacted mandibular third molars vertically erupt as a result of uprighting with mesialization of the second molar, and vertical eruption is affected by the initial vertical location of impacted third molars and available space.

Abstract BackgroundExtraction of mandibular third molars is one of the most commonly performed oral surgical procedures, and non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for pain management. Oral administration of NSAIDs produces various adverse events such as gastrointestinal disorders, renal and hepatic dysfunction, and platelet dysfunction. Topical use of analgesics has been proposed as an alternative to oral and injectable medications to safely improve postoperative pain relief. We will conduct a single-center, placebo-controlled, double-blind, randomized crossover trial to assess the pain-relieving effect of an ibuprofen-containing gargle in patients undergoing extraction of mandibular third molars in comparison with a placebo gargle.MethodsThis study will be performed at Kobe University Hospital. Participants (n = 40) will be randomized equally to one of two groups. The IP group will receive ibuprofen gargle on postoperative day (POD) 1 and placebo gargle on POD 2. The PI group will receive placebo gargle on POD 1 and ibuprofen gargle on POD 2. Both groups will receive ibuprofen gargle on PODs 3 to 5 at least once daily. The primary objective is to estimate the within-subject difference in a visual analogue scale (VAS) before and 5 minutes after use of ibuprofen or placebo gargle on PODs 1 and 2. The secondary objectives are to estimate the within-subject difference in ΔVAS before and 15 minutes after use of ibuprofen or placebo gargle on PODs 1 and 2, the ΔVAS before and after 5 or 15 minutes of use of ibuprofen gargle on PODs 3 to 5, the overall effectiveness (self-completion, five scales) on PODs 1 to 5, the daily frequency of use (ibuprofen or placebo gargle and analgesics) on PODs 1 to 7, and the occurrence of adverse events.DiscussionThis will be the first well-designed clinical study to evaluate the efficacy of ibuprofen gargle for relieving postoperative pain after extraction of mandibular third molars. This trial will provide exploratory evidence of the efficacy and safety of ibuprofen gargle for pain reduction after mandibular third molar extraction.Trial registrationJapan Registry of Clinical Trials (jRCT) identifier: jRCTs051210022.

Aim: To analyse early recognition of the distal cervical caries of mandibular second molar caused by impacted mandibular third molar, to correlate oral health and caries status and to find out the average age groups and gender affected by impacted third molar Methods: A cross-sectional survey of 300 participants was conducted over a 15-month period at Rehmat Memorial Hospital, Abbottabad. 300 participants having impacted third molar having distal cervical caries in mandibular second molar were analyzed clinically and radiographically. Data was analyzed using SPSS version 23.0 Results: the demographic data of 300 patients with impacted mandibular third molars were analyzed. 64% were male and 36% female that have extractions due to impaction. Caries caused in more than half of participants by mesioangular impaction, which was 52%, 3% due to distoangular, 26% due to distal, and 18% due to horizontal impaction. In 63.25% of cases, teeth were lost due to caries, periodontitis caused 20.25% of tooth loss, pericoronitis 7.75%, orthodontics 3.75%, prosthodontics 1.2%, trauma 1%, and other factors were 2.5%. study reveals that 30.5 % of the extractions were done from 21 and 30 years and 23 %of extractions were performed. 40% of those who took part in the study did not brush their teeth. Socioeconomic status also has a great impact on tooth extractions. Conclusion: After conducting this study, it was concluded that there was a relationship between the prevalence of distal cervical caries in mandibular second molars and the placement of neighbouring impacted mandibular third molars. As a result, the extraction of mandibular third molars should be done to avoid cavities and premature tooth loss in the neighboring molar.

To evaluate the associations of impaction patterns of mandibular third molars (M3Ms) with pathologies caused by them. In this study, 262 patients with 432 impacted M3Ms who referred in Shanghai Xuhui District Center were reviewed. The pathologies include pericoronitis, mandibular second molar (M2M) caries, and M2M distal periodontal pathology. The impaction patterns of M3Ms and the pathologies were examined, while the M2M outcomes after surgeries were evaluated. A χ2 test was used to analyze the data, with a p value of <0.05 being considered statistically significant. Pericoronitis was the major symptom in all patients, whereas the propensities of M2M distal caries and periodontal pathologies increased in older patients. Soft tissue impacted and vertically angulated teeth were more associated with pericoronitis ( p < 0.05); mesio-angular impacted teeth in less deep positions had greater risks of M2Ms distal caries ( p < 0.05); mesio-angular and horizontal impacted teeth in relative deep positions were more likely to cause M2Ms distal periodontal pathologies ( p < 0.05). Extractions of soft tissue impacted teeth in vertical angulations should be considered, while removals of mesially and horizontally angulated or bony impacted teeth could be delayed.

ABSTRACT The purpose of this study is to analyze the incidence of complications in a group of 171 patients in whom extractions of impacted mandibular third molar have been performed by two oral surgeons between the period April 2010 and March 2012. This retrospective study comprises evaluation of 270 impacted mandibular third molars which were classified into two groups A and B on the basis of procedure of osteotomy only and osteotomy and odontotomy both respectively. Total no of complications reported were 40 (14.81%). Maximum no of cases reported alveolar osteitis (AO) (11.11%) while other complications reported root tip fractures (2.22%), lingual nerve parasthesia and TMJ problems (each 0.74%) in descending frequency. Conclusion drawn is that the risk of complications in extractions of impacted mandibular third molars always exists, and extractions associated with both osteotomy and odontotomy are associated with higher risk of complications.

OBJECTIVE: This study was conducted to observe the relationship of mesio-angular impacted third molars to the development of distal caries in adjacent second molars. METHODOLOGY: This cross-sectional study was conducted at Nishtar Institute of Dentistry, Multan. Nine hundred and eighty nine periapical, bitewing and Panoramic radiographs were recorded and examined for distally carious second molars and impacted mandibular third molars. SPSS version 23.0 was used for data entry and analysis. RESULTS: Almost 40.8% of the target population reported with distal caries due to third molar impactions. A total of 53.30% of these impactions were of the mesio-angular variety. No distal caries was detected in transverse type of impactions. CONCLUSION: The current study concluded that the prevalence of distal caries in mandibular second molars and the positioning of adjacent impacted mandibular third molars in the dental arch were interlinked. Consequently, extraction of mandibular third molars should be considered to prevent caries and premature loss of second molar teeth.
