Prevalence and Pattern of Distribution of Impacted Mandibular Third Molars on Digital Panoramic Radiograph among Central Kerala Population: A Cross Sectional Study

INTRODUCTION: Impaction may be defined as the failure of complete eruption into a normal functional position of one tooth within normal time due to lack of space in the dental arch, caused by obstruction by another tooth or development in an abnormal position.MATERIAL AND METHODS: A cross sectional descriptive study was conducted on 945 patients (males=591, females=354) aged between 18- 50 years of age who had mandibular third molars impacted. The difficulty index for mandibular third molar for angulation and depth was based on Winter’s classification (1926).RESULTS: The most common type of impaction seen was Mesio- angular with (32%) followed by horizontal 264 (27.8%), then followed by other types. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 23.0CONCLUSION: Impacted third molars are a common observation in routine dental practice. The impaction rate of third molars is higher as compared to other teeth in the dentition. The high prevalence found in the present study, with more than half of these Nepalese adult patients having at least one impacted third molar.

Introduction: The purpose of this study was to assess the various indications of impacted mandibular third molar removal and pathologies associated with it. Methods: A retrospective cross-sectional study was conducted in the Department of Oral Surgery, Gandaki Medical College. The clinical case records from September 2016 to August 2019 were retrieved, reviewed, and analyzed. Surgically removed impacted mandibular third molars for which orthopantomogram were available and the lesions verified histologically were included in the study. Orthopantomograms were studied to determine the angular position of the impacted mandibular third molars and associated pathology. The data was entered in SPSS 20 and descriptive statistics was applied. Results: A total of 1344 impacted mandibular third molars (Male-709, 52.8%; Female - 635, 47.2%) were surgically extracted during the three-year period. The majority of patients (36.5%) were in the age groups of 25 - 34 years with a higher incidence of mesioangular impaction (33%). Recurrent pericoronitis (62.9%) was the most common indication followed by caries (11.7%). The radiographically detectable lesion was seen in 471 (35%) cases out of which 304 (64.5%) were symptomatic at the time of extraction. Among137 histopathologically diagnosed cases, chronic inflammatory lesion (76, 55.9%) was the most common finding. Conclusion: Awareness of the indications for removal of impacted mandibular third molars helps in proper management and prevention of future complications associated with retention and delayed extraction of such teeth. So, regular and periodic clinical and radiographic examination is required for patients with impacted mandibular third molars.

The Impact

Abstract: Dental tooth impaction is a state of latent or not erupted or partly erupted after a normal eruption time. The impact of impacted teeth, namely the absence of pain, inflammation, and cysts but the prevalence of impacted teeth in several countries including in Indonesia is quite high. Some areas in Indonesia yet has particularly impacted teeth, especially data on partial erupted. This study aims to determine the prevalence of impacted teeth partially erupted on Totabuan Village community. This research is a descriptive cross sectional study. The study population is villagers Totabuan, the study sample as many as 37 people are 13 men and 24 women aged 24-60 years. Results of studies have impacted teeth partially erupted third molars most women (60%), and more common in the age of 24-35 years (62%). Partially erupted tooth impaction occurs most often in the lower jaw (53%) with most gear position on mesioangular (48.4%).Keywords: dental impaction, partial erupted.Abstrak: Gigi impaksi merupakan suatua keadaan gigi terpendam atau tidak erupsi baik sebagian maupun seluruhnya setelah melewati waktu erupsi normal. Dampak dari gigi impaksi yaitu adanya rasa sakit, inflamasi, serta kista akan tetapi prevalensi gigi impaksi di beberapa negara termasuk di Indonesia cukup tinggi. Beberapa daerah di Indonesia belum meiliki data mengenai gigi impaksi khususnya partial erupted. Penelitian ini bertujuan untuk mengetahui prevalensi gigi impaksi partial erupted pada masyarakat Desa Totabuan. Penelitian ini merupakan penelitian deskriptif dengan rancangan cross sectional study. Populasi penelitian yaitu masyarakat Desa Totabuan, dengan sampel penelitian sebanyak 37 orang yaitu 13 orang laki-laki dan 24 orang perempuan dengan usia 24-60 tahun. Hasil penelitian ditemukan adanya gigi impaksi molar tiga partial erupted paling banyak pada perempuan (60%), dan banyak ditemukan pada usia 24-35 tahun (62%). Gigi impaksi partial erupted paling sering terjadi pada rahang bawah (53%) dengan posisi gigi paling banyak pada mesioangular (48,4%). Berdasarkan penelitian yang telah dilakukan dapat disimpulkan bahwa gigi impaksi molar tiga partial erupted yang paling banyak ditemukan pada perempuan, dan banyak ditemukan pada usia yaitu 24-35 tahun. Gigi impaksi molar tiga partial erupted paling banyak ditemukan pada rahang bawah, dengan posisi gigi paling banyak pada mesioangular.Kata kunci: gigi impaksi, partial erupted.

The Relationship

The aim of the present study was to assess the positive predictive value (PPV) of panoramic radiographic signs in the assessment of the relationship between impacted mandibular third molars (IMTMs) and the mandibular canal (MC). This cross-sectional study was conducted by reviewing 102 cone-beam computed tomography (CBCT) and panoramic radiographs of patients with IMTMs and radiographic signs of the contact of the IMTMs with the MC on panoramic radiographs (i.e., root apex darkening and interference with the white line). A positive relationship of the IMTM roots with the MC based on CBCT findings was recorded as the gold standard. The PPV of panoramic radiographic signs was calculated for the detection of the relationship of the IMTM root with the MC. The IMTMs were in contact with the MC on CBCT scans in 90.1% of the cases. The PPV of root apex darkening and the interference with the white line was found to be 89.09% (95% CI: (77.75, 95.88)) and 91.48% (95% CI: (79.62, 97.63)), respectively. The MC had a buccal position in 63.7%, and a lingual position in 35.2%, of the cases. The contact of IMTMs with the MC was more commonly seen in patients with a lingual position (100% of the samples). The IMTM root apex darkening and interference with the white line of the MC on panoramic radiographs had a high PPV for determination of the contact of IMTMs with the MC. Thus, presence of the above-mentioned risk factors indicates the need for subsequent 3D radiographic assessments.

Objective: This study aimed to assess and compare the knowledge and awareness of dental interns and general practitioners in Saudi Arabia about late mandibular incisor crowding. Materials and methods: This is a cross-sectional study which was conducted between June 2020 and July 2020 in Saudi Arabia and it observed dental practitioners. Results: A total of 275 subjects were included in this study; 172 (62.5%) were dental interns, 157 (57.1%) were females and 211 (76.7%) dentists were aged between 23-26 years. While most general practitioners and dental interns have heard about late mandibular incisors crowding, the majority continue to abstain from not recommending extraction of lower third molar as a means of prevention. Around half of the respondents, 134 (48.7%), claimed that the eruption of lower third molars is a possible causative factor. A greater percentage of general dental practitioners, 32 (31.1%) believed that there is a correlation between late mandibular incisors crowding and cases of relapse after an orthodontic treatment. Moreover, male participants were more knowledgeable of the fact that cases may worsen if not treated (P = 0.019). The knowledge of lower third molars eruption (P = 0.002) and unerupted/impacted lower third molars (P = 0.034) ability to cause late mandibular incisors crowding and the prophylactic extraction of the lower third molars (P = 0.009) were also significantly differed across the various age groups. Conclusion: Late mandibular incisor crowding is one of the main clinical issues in dental practice which has been subject to decreased awareness among dentists. Keywords:Dentists, knowledge, late mandibular incisor crowding, Saudi Arabia.
