Abstract

Pendahuluan: Bruxism adalah aktivitas parafungsi oklusal pada siang atau malam hari dimana terjadi grinding, clenching, dan gnashing. Bruxism dapat memberikan tekanan berlebih pada tulang sehingga tulang beradaptasi melalui proses remodeling tulang yang dapat mengubah jumlah, densitas, dan ketinggian tulang. Perubahan yang terjadi pada tulang dapat dianalisis dengan mengukur ketinggian tulang kortikal mandibula. Salah satu metode pengukuran yang dapat digunakan adalah indeks panoramik mandibula (PMI) melalui radiografi panoramik. Tujuan penelitian ini adalah menganalisis perbedaan ketinggian tulang kortikal mandibula pada penderita dan bukan penderita bruxism. Metode: Jenis penelitian ini adalah analitik cross sectional. Sampel penelitian ini terdiri dari dua kelompok, yaitu 30 sampel radiograf panoramik digital penderita bruxism dan 30 sampel radiograf panoramik digital bukan penderita bruxism. Data dianalisis menggunakan independent t-test pada software MegaStat 10.1. Hasil: Hasil analisis p-value menunjukkan ketinggian tulang kortikal mandibula regio kanan penderita bruxism dan bukan penderita bruxism adalah 0,1517mm dan regio kiri adalah 0,2036mm (p-value&gt;0,05). Simpulan: Tidak terdapat perbedaan ketinggian tulang kortikal mandibula antara penderita bruxism dan bukan penderita bruxism.Kata kunci: Bruxism, kortikal mandibula, indeks panoramik mandibular. ABSTRACTIntroduction: Bruxism is an occlusal parafunction activity during the day or night that includes grinding, clenching, and gnashing. Bruxism can exert excessive pressure on the bone so that the bone adapts through the process of bone remodelling, which can change the amount, density, and height of the bone. Changes that occur in the bone can be analysed by measuring the height of the mandibular cortical bone. One of the measurement methods commonly used was the panoramic mandibular index (PMI) through panoramic radiography. The purpose of this study was to analyse the differences in the height of the mandibular cortical bone in bruxism and non-bruxism patients. Methods: The type of research was cross-sectional analytic. The sample of this study consisted of two groups, which were 30 samples of digital panoramic radiographs of bruxism patients and 30 samples of digital panoramic radiographs of non-bruxism patients. Data were analysed using an independent t-test in the MegaStat 10.1 software. Results: The results of the p-value analysis showed that the mandibular cortical bone in the right region of bruxism and non-bruxism patients was 0.1517 mm, and in the left region was 0.2036 mm (p-value &gt; 0.05). Conclusion: There is no difference in the mandibular cortical bone height between bruxism and non-bruxism patients.Keywords: Bruxism, mandibular cortical bone, panoramic mandibular index.

Evaluation of Bone Quality in Patients With Bruxism

“…As far as we know, there are few studies in the literature evaluating the bone quality of patients with bruxism using radiomorphometric indices on OPG [2,13,14,17]. The rst study reporting the relationship between radiomorphometric indexes and bruxism is Isman's study in 2020 [2].…”

“…Aziza et al [14], who measured the mandibular cortical bone height according to GI and AI on OPGs in 30 bruxer and 30 non-bruxer individuals, found that these two index values were not statistically different between bruxer and non-bruxer individuals. In another similar study, Fauziah et al [17] formed two groups: 30 digital OPG samples of patients with bruxism and 30 digital OPG samples of patients without bruxism. They reported that there was no signi cant difference in the height of the mandibular cortical bone between bruxism patients and non-bruxism patients based on PMI.…”

Bruksizmli Hastaların Radyograflarında Hounsfield Birim Değeri ve Radyomorfometrik İndekslerinin Değerlendirilmesi

“…These changes should be considered when planning dental treatment in patients with bruxism Therefore, in our study, the effects of bruxism on bone mineral density and shape were evaluated using HU value and radiomorphometric indices (9). As far as we know, there are few studies in the literature evaluating radiomorphometric indices on DPRs of bruxism (7,(11)(12)(13). The first study reporting the relationship between radiomorphometric measurements and bruxism status is Isman's (2020) study (7).…”

Differences in Panoramic Mandibular Index value between male and female hypertension patients using panoramic radiography

“…The examination of panoramic radiography is conducted using several qualitative and quantitative indices, namely mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI), and gonion antegonial index. 10,12 PMI is an index that provides results in the form of a comparison between the thickness of the mandibular cortex and the distance from the inferior mental foramen to the inferior border of the mandibular cortex. Therefore, this measurement method allows calculations to be performed despite variations in magnification by different researchers.…”

“…Therefore, this measurement method allows calculations to be performed despite variations in magnification by different researchers. 12,13,14 Based on the statement above, the researchers are interested in determining the differences in panoramic mandibular index values between male and female hypertensive patients using panoramic radiography.…”
