Fulltext Effects of impacted lower third molar removal on alveolar bone height and periodontal parameters of adjacent second molar

Wan Nur Alwani Wan Abdul Aziz, Azlan Jaafar, Ahmad Dzulfikar Samsudin

International Medical Journal Malaysia, 2017;16(21):8-8.
MyJurnal

The effect of surgical removal of impacted third molars on the periodontal
parameters of adjacent second molar revealed inconsistent results. Some authors suggested
improvement of periodontal parameters distal to second molar, whilst others demonstrated loss of
attachment and reduction of alveolar bone height. This study was conducted to evaluate the
alveolar bone height (ABH) and periodontal status of second molar after the surgery. (Copied from article).

Majid H, Ramachandra SS, Kumar S, Wei M, Gundavarapu KC

Compend Contin Educ Dent, 2022 Jan;43(1):e5-e8.
PMID: 35019665

This study evaluated the effect of alloplastic bone grafts in osseous defects following surgical removal of horizontally impacted third molars by comparing the periodontal measures distal to the second molar in grafted and nongrafted third molar extraction sites. Materials and Methods: A double-blind, randomized, controlled clinical trial was designed on subjects with bilateral horizontally impacted mandibular third molars. Grafting consisting of alloplasts at the third molar extraction sites was compared with nongrafted sites. This study assessed 54 randomized sites in 27 patients who were selected using a split-mouth design. The predictor variable included the change in pocket depth distal to the mandibular second molar and associated dentin hypersensitivity around the second molar, assessed preoperatively and at 3 and 6 months after third molar surgery. The data regarding pocket depth reduction was statistically analyzed using paired t-test. The data concerning reduction in dentin hypersensitivity was statistically analyzed using chi-square test. Results: Six months after third molar surgery, mean pocket depth distal to mandibular second molar decreased significantly at the grafted sites compared to the nongrafted sites. The reduction in dentin hypersensitivity of mandibular second molar was statistically significant for the grafted sites at 6 months, compared to the nongrafted sites.

Is there a need for postoperative antibiotics after third molar surgery? A 5-year retrospective study

Menon RK, Kar Yan L, Gopinath D, Botelho MG

J Investig Clin Dent, 2019 Nov;10(4):e12460.
PMID: 31608608 DOI: 10.1111/jicd.12460

AIM: Randomized controlled trials might be reporting a higher postoperative infection rate for third molar surgery compared to other study designs due to unclear criteria for the classification of "infections". The aim of the present retrospective study was to assess the infection rate after third molar surgery with and without postoperative antibiotic prescription.
METHODS: Case records of patients who underwent third molar extractions at the Prince Philip Dental Hospital in Hong Kong between 3 July 2012 and 22 June 2017 were evaluated retrospectively. Data extraction was performed for indications, clinical and radiographic findings, antibiotic treatment, postoperative complications, and treatment for postoperative infection. The odds ratio (OR) for postoperative infection was estimated.
RESULTS: In total, 1615 extracted over 5 years from 992 patient records were included in the final analysis. Antibiotics were prescribed postoperatively for 44% of the extractions. The overall infection rate was 2.05%. There was no significant difference in infection rates between the groups which underwent extractions with or without antibiotics (OR = .68; P = .289). We found a significantly higher risk for infections with increasing age (P = .002).
CONCLUSION: Infection rates after third molar extraction is minimal in the current setting, with no significant benefit from postoperative antibiotic prescription.

Fulltext Rare morphology of the third maxillary molar and potential complications in its extraction

Siti Mazlipah Ismail, Firdaus Hariri

Ann Dent, 2020;27(1):66-68.
MyJurnal

There is a wide variation in the morphology of third maxillary molar which can be difficult to be identified radiographically. We present a case of a 26 year-old Yemeni female patient presented with difficult extraction of her left maxillary third molar. The extracted tooth showed a rare variation of root morphology, having four roots with three roots curving palatally at the apices. This report emphasized the potential complex morphological variation of maxillary third molar which may lead to the difficulty of a routine straight forward procedure thus needing careful extraction maneuvering to prevent any complications.

PMID: 24967595 DOI: 10.1371/journal.pone.0101157

To investigate the presence and/or agenesis of third molar (M3) tooth germs in orthodontics patients in Malaysian Malay and Chinese population and evaluate the relationship between presence and/or agenesis of M3 with different skeletal malocclusion patterns and sagittal maxillomandibular jaw dimensions. Pretreatment records of 300 orthodontic patients (140 males and 160 females, 219 Malaysian Malay and 81 Chinese, average age was 16.27±4.59) were used. Third-molar agenesis was calculated with respect to race, genders, number of missing teeth, jaws, skeletal malocclusion patterns and sagittal maxillomandibular jaw dimensions. The Pearson chi-square test and ANOVA was performed to determine potential differences. Associations between various factors and M3 presence/agenesis groups were assessed using logistic regression analysis. The percentages of subjects with 1 or more M3 agenesis were 30%, 33% and 31% in the Malaysian Malay, Chinese and total population, respectively. Overall prevalence of M3 agenesis in male and female was equal (P>0.05). The frequency of the agenesis of M3s is greater in maxilla as well in the right side (P>0.05). The prevalence of M3 agenesis in those with a Class III and Class II malocclusion was relatively higher in Malaysian Malay and Malaysian Chinese population respectively. Using stepwise regression analyses, significant associations were found between Mx (P<0.05) and ANB (P<0.05) and M3 agenesis. This multivariate analysis suggested that Mx and ANB were significantly correlated with the M3 presence/agenesis.

Dens evaginatus on a wisdom tooth: a diagnostic dilemma. Case report

Ngeow WC, Chai WL

Aust Dent J, 1998 Oct;43(5):328-30.
PMID: 9848984

Pericoronitis is the most common odontogenic problem associated with the wisdom tooth in young men and women. Patients may present with problems associated with infection, swelling and pain. However, other associated pathology such as caries, periodontal disease and referred pain from the temporomandibular joint must be investigated when treating pain from the wisdom tooth. The authors wish to present a case in which the pain from a wisdom tooth was due to a fractured dens evaginatus. The importance of this dental anomaly should not be overlooked.

Fulltext The use of gutta-percha point to locate the origin of facial sinus

Ngeow WC

Med J Malaysia, 1997 Jun;52(2):181-2.
PMID: 10968080

Infection from the wisdom teeth usually causes severe swelling at the region of the angle and body of the mandible. Occasionally, it tracts outward to form a cervicofacial sinus. This paper demonstrates the use of gutta-percha point to locate the origin of a cervicofacial sinus due to an asymptomatic impacted wisdom tooth. The advantage of using gutta-percha point is discussed.

Niger J Clin Pract, 2021 Jul;24(7):1028-1036.
PMID: 34290179 DOI: 10.4103/njcp.njcp_499_20

Background: Third molar impaction, if left untreated, has the potential to cause several complications. The evaluation of surgical difficulty of impacted third molar extraction aids in better formulation of treatment plan by minimizing surgical complications.
Objective: This study aimed to determine the prevalence of third molar impaction and related pathologic conditions in a cohort of patients living in North-eastern Peninsular Malaysia.
Methods: In this retrospective study, 490 orthopantomograms (OPGs) of patients who were referred to the Oral and Maxillofacial Surgery department between January 2010 and December 2019 were assessed. Data including age, gender, ethnicity, frequency of third molar impactions, their angulations and levels of eruption, retromolar space, and associated pathologic conditions were collected. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 24.0. The significance level was set to P < 0.05.
Results: A total of 490 patients with a mean age of 28.87 years (range: 20-64) demonstrated 1957 impacted third molars (1022 mandibular + 935 maxillary). Impacted third molars were more likely present in females than males (1:2.20) (p < 0.05); and in Malay-ethnic (44.49%) patients followed by Chinese (34.45%) and Indians (21.02%). Mesioangular was the most common angulation of impaction both in the maxilla (24.68%) and mandible (18.34%). The most common pattern of third molar impaction was IIA (61.67%), and the retromolar space was significantly larger in males (13.6 mm; P < 0.05) than females (11.6 mm). The most frequently occurring pathological condition associated with third molars impaction is dental caries in the second or third molar (15.38%).
Conclusions: This study highlights mesioangular impaction with their occlusal plane at the same level as the occlusal plane of the adjacent tooth being the most prevalent pattern of third molar impaction in North-eastern Peninsular Malaysia.

Fulltext Variation in Lingual Nerve Course: A Human Cadaveric Study

Al-Amery SM, Nambiar P, Naidu M, Ngeow WC

PLoS One, 2016 09 23;11(9):e0162773.
PMID: 27662622 DOI: 10.1371/journal.pone.0162773

The lingual nerve is a terminal branch of the mandibular nerve. It is varied in its course and in its relationship to the mandibular alveolar crest, submandibular duct and also the related muscles in the floor of the mouth. This study aims to understand the course of the lingual nerve from the molar area until its insertion into the tongue muscle. This cadaveric research involved the study of 14 hemi-mandibles and consisted of two parts: (i) obtaining morphometrical measurements of the lingual nerve to three landmarks on the alveolar ridge, and (b) understanding non-metrical or morphological appearance of its terminal branches inserting in the ventral surface of the tongue. The mean distance between the fourteen lingual nerves and the alveolar ridge was 12.36 mm, and they were located 12.03 mm from the lower border of the mandible. These distances were varied when near the first molar (M1), second molar (M2) and third molar (M3). The lingual nerve coursed on the floor of the mouth for approximately 25.43 mm before it deviated toward the tongue anywhere between the mesial of M1 and distal of M2. Thirteen lingual nerves were found to loop around the submandibular duct for an average distance of 6.92 mm (95% CI: 5.24 to 8.60 mm). Their looping occurred anywhere between the M2 and M3. In 76.9% of the cases the loop started around the M3 region and the majority (69.2%) of these looping ended at between the first and second molars and at the lingual developmental groove of the second molar. It gave out as many as 4 branches at its terminal end at the ventral surface of the tongue, with the presence of 2 branches being the most common pattern. An awareness of the variations of the lingual nerve is important to prevent any untoward complications or nerve injury and it is hoped that these findings will be useful for planning of surgical procedures related to the alveolar crest, submandibular gland/ duct and surrounding areas.

MyJurnal

In the present case, granuloma formation and loss of tooth vitality following the use of bone wax in third molar surgery in a 16 - year- old male patient were reported. Endodontic and surgical treatments were carried out on the patient. As foreign body granulomatous reaction to bone wax is not uncommon in the literature review, alternative haemostatic agents should be taken into consideration to avoid any potential complications and untoward effects of using bone wax for haemorrhage control in surgical procedures.

Fulltext Endodontic Management of a Severely Dilacerated Mandibular Third Molar: Case Report and Clinical Considerations

Arora S, Gill GS, Setia P, Abdulla AM, Sivadas G, Vedam V

Case Rep Dent, 2018;2018:7594147.
PMID: 30402298 DOI: 10.1155/2018/7594147

This article aims at providing an insight to the clinical modifications required for the endodontic management of severely dilacerated mandibular third molar. A 35-year-old patient was referred for the root canal treatment of the mandibular left third molar. An intraoral periapical radiograph revealed a severe curvature in both the canals. A wide trapezoidal access was prepared following the use of intermediate-sized files for apical preparation. Owing to increased flexibility, Hero Shaper NITI files were used for the biomechanical preparation and single cone obturation was carried out. Third molars owing to their most posterior location-limited access coupled with a severe curvature pose utmost clinical challenges require meticulous skill, advanced technology, and patience to achieve success.

Mandibular third molar and angle of mandible fractures: an unsolved clinical dilemma

Rajandram R, Nabil S, Shareif M, Ishak I, Marhazlinda J, Nordin R, et al.

Sains Malaysiana, 2013;42:39-43.

The purpose of this study was to investigate the relationship between partially erupted impacted mandibular third and the risk for angle of mandible fracture. We designed a retrospective cohort study composed of patients who presented with mandible fractures. The predictor variables were the presence and angulation of the partially erupted impacted mandibular third molar and the distance between the apices of the mandibular third molar and the inferior border of the mandible. The outcome variable was the presence or absence of an angle fracture. Patients with a partially erupted impacted mandibular third molars had a 3.3 times greater chance of an angle fracture than patients without mandibular third molars (p<001). No significant association was found between the distance of the apices and angulation of the mandibular third molars to the inferior border of the mandible with angle of mandible fractures. Our findings highlight the need for enforcement of proper protective gear in young individuals who are at high risk for facial trauma.

PMID: 23000811

This study aimed to assess the variability of the lower third molar (tooth 38 and 48) development in Northeast Malaysian population with respect to the side of dentition, to generate age prediction models and to compare the outcome with other studies. A total of 1080 orthopantomograms of Northeast Malaysian population aged between 14 and 25 years (540 males and 540 females) from the Hospital Universiti Sains Malaysia's archive which met the inclusion and exclusion criteria were selected and the maturity stages of tooth 38 and 48 were scored using Demirjian's stages (A-H). The findings showed a wide variation of the development of lower third molars in the Northeast Malaysian population. The roots developed earlier in males than in females. The development of the dentition on opposite sides of the mandible was synchronously in females and males. A multiple regression analysis shows that 71.1% of variance in age was explained by sex and developmental stage of tooth 48. An age prediction model was generated from the regression analysis: [Age = 7.117 + 1.907*(stage of tooth 48) - 0.432*(sex)] with mean prediction errors between -0.17 to 3.14 years. The obtained data in the current study are useful for references and determining age of unidentified human remains for identification investigation.

The third molar development (TMD) has been widely utilized as one of the radiographic method for dental age estimation. By using the same radiograph of the same individual, third molar eruption (TME) information can be incorporated to the TMD regression model. This study aims to evaluate the performance of dental age estimation in individual method models and the combined model (TMD and TME) based on the classic regressions of multiple linear and principal component analysis. A sample of 705 digital panoramic radiographs of Malay sub-adults aged between 14.1 and 23.8 years was collected. The techniques described by Gleiser and Hunt (modified by Kohler) and Olze were employed to stage the TMD and TME, respectively. The data was divided to develop three respective models based on the two regressions of multiple linear and principal component analysis. The trained models were then validated on the test sample and the accuracy of age prediction was compared between each model. The coefficient of determination (R²) and root mean square error (RMSE) were calculated. In both genders, adjusted R² yielded an increment in the linear regressions of combined model as compared to the individual models. The overall decrease in RMSE was detected in combined model as compared to TMD (0.03-0.06) and TME (0.2-0.8). In principal component regression, low value of adjusted R(2) and high RMSE except in male were exhibited in combined model. Dental age estimation is better predicted using combined model in multiple linear regression models.

Third molars in the establishment of adult status--a case report

Nambiar P, Yaacob H, Menon R

J Forensic Odontostomatol, 1996 Dec;14(2):30-3.
PMID: 9227080

Teeth are the most durable structures in the human body. The timing and sequence of their development, as contained in dental development charts, have been used as valid criteria for age determination. The third molars however are the last teeth to erupt and are regarded as the most variable in the dentition. Age estimation in a legal context, using developing third molars must be carefully applied otherwise justice may miscarry. A case of wrongful use of the technique is presented here.

Fulltext Paradental Cyst Associated With an Unerupted Wisdom Tooth

Ngeow, W.C., Zain, R.B., Chai, W.L.

Ann Dent, 2000;7(1):-.
MyJurnal

The paradental cyst is an odontogenic cyst occurring near to the cervical margin of the lateral aspect of a root as a consequence of an inflammatory process in a periodontal pocket. A distinct form of the paradental cyst occurs not infrequently on the buccal aspects of erupted mandibular third molar, where there is an associated history of pericoronitis. A search of the literature revealed that these cysts had all been reported in relation to partially, newly or fully erupted molars. This report presents one case in which the cyst was noticed to be associated with an unerupted third molar. The histological appearance of the cyst and the gross relationship to the cemento-enamel junction is similar to those typical of paradental cysts reported in the literature. However, the radiographic and clinical appearance of the tooth being unerupted do not tally with paradental cyst and yet exclude the diagnosis of dentigerous cyst. The diagnosis of dental follicular tissue was excluded based on the histopathological presentation. The authors suggested that this case may represent an early form of paradental cyst which in the past may have been dismissed as dental follicular residues and thus, the prevalence of paradental cyst may have been under reported in the literature.
