“…[12] In addition to these metallic ions, the composites used for bonding the bracket al so releases a variety of monomers that will have a toxic effects on adjacent oral tissue. [13] Localized corrosion can be due to plaque, acids produced by the microorganisms, and physicochemical events such as inflated levels of oxygen in saliva leading to DNA fragmentation in the buccal mucosa. [14] The residual monomers are ingested or absorbed into the digestive system through the saliva from mucosa of the mouth or pharynx.…”

“…Additionally, deep cells are rarely detected in healthy tissues, corroborating the notion that LBEC is an accurate and useful method for the evaluation and early detection of alterations that precede clinical manifestations in the oral mucosa. 27 Cell changes are an adaptive response to irritation of the oral mucosa. The cell nucleus may have a marked increase in volume, with uniform distribution of nuclear chromatin granules (karyomegaly).…”

BackgroundThe oral mucosa is an important defense barrier to penetration of microorganisms. Thus, changes in the oral epithelium might indicate risk for infection in intensive care patients receiving mechanical ventilation. Objective To evaluate the oral mucosa of intensive care patients who did or did not receive mechanical ventilation by using liquid-base exfoliative cytology. Methods The sample consisted of 3 groups: 27 patients admitted to intensive care during a 7-to 14-day period who received mechanical ventilation, 29 patients admitted during the same period who did not receive mechanical ventilation, and 27 healthy patients who had no lesions in the mouth. For all 3 groups, samples were collected from the buccal mucosa by using cytology brushes. Smears were applied to glass slides before Papanicolaou staining and were codified for blind analyses by a cytopathologist. Kruskal-Wallis and Dunn tests were used to analyze the results. Results Patients receiving mechanical ventilation had higher prevalence and intensity of karyomegaly, perinuclear halos, cell keratinization, deep cells, and leukocyte infiltrates than did patients in the other 2 groups (P < .05). No significant differences were observed between the control group and the group who did not receive mechanical ventilation. Conclusions Liquid-base exfoliative cytology can be used to detect preclinical alterations in the oral mucosa. Patients treated with mechanical ventilation are vulnerable to infections, and oral care may be valuable in their prognosis.

“…pada tahun 2011 yang mendapati pengaruh band tube terhadap mukosa mulut lebih kecil jika dibandingkan bracket. 23 Tidak ditemukannya ulkus traumatik yang disebabkan oleh lock-pins dalam penelitian ini, karena pada jenis alat ortodontik yang digunakan responden tidak terdapat komponen lock-pins.…”

“…Terkait dengan efek-efek tersebut, atrofi sel dapat meningkat sampai pada kondisi dimana sel terluka dan mati. 23 Ulkus yang disebabkan karena penyesuaian mukosa dengan alat biasanya terjadi pada saat adanya pergantian komponen alat. Pergantian komponen alat ini dilakukan operator melalui kontrol pasien setiap dua minggu sekali, sebulan sekali, atau enam bulan sekali, namun pada kebanyakan responden dalam penelitian ini, ulkus hanya terjadi jika ada kerusakan pada alat ortodontik atau terdapat komponen tertentu yang dapat menyebabkan iritasi mukosa sehingga frekuensinya tidak teratur.…”

Ulkus traumatik merupakan lesi ulseratif pada mukosa mulut yang disebabkan oleh trauma. Salah satu penyebabnya yaitu penggunaan alat ortodontik cekat. Adanya ulkus traumatik dapat menimbulkan ketidaknyamanan pada mulut pasien selama perawatan ortodontik.Penelitian ini bersifat deskriptif, bertujuan untuk mengetahui gambaran ulkus traumatik pada pengguna alat ortodontik cekat di Program Studi Kedokteran Gigi Fakultas Kedokteran Universitas Sam Ratulangi. Sampel penelitian ini sebanyak 61 orang yang diambil dengan teknik total sampling. Data diperoleh berdasarkan wawancara terhadap responden.Hasil penelitian menunjukkan bahwa 90,1% mahasiswa pengguna alat ortodontik cekat di PSKG FK-UNSRAT pernah mengalami ulkus traumatik, dimana perempuan lebih banyak mengalami ulkus dibandingkan laki-laki. Sebanyak 60% responden menyatakan ulkus pertama kali terjadi pada periode < 1 bulan setelah penggunaan alat. Lokasi terjadinya ulkus yaitu pada mukosa pipi 80% dan mukosa bibir 20%. Penyebab ulkus traumatik yang paling sering yaitu kawat (56,3%). Ulkus yang terjadi dengan frekuensi tidak teratur ditemui pada 72,7% responden. Sebanyak 43,7% responden membiarkan ulkus tanpa perawatan, 12,7% berobat ke dokter gigi dan 40% responden mengobati sendiri, dimana 63% diantaranya menggunakan obat topikal.Kata kunci: ulkus traumatik, alat ortodontik cekat.ABSTRACTTraumatic ulcer is an oral mucosa ulcerative lesion caused by trauma. One of the causes is the using of fixed orthodontic appliance. Traumatic ulcer can give an uncomfortable feeling to the patients during the orthodontic treatment.This is a descriptive study that aims to know the traumatic ulcer of the fixed orthodontic appliance users in dentistry student of Medical Faculty Sam Ratulangi University. The samples were 61 people taken by total sampling technique. Data was obtained by interviewing the respondent.The result showed that 90.1% of orthodontic patients had experienced traumatic ulcer, more girls than boys. About 60% respondents had experienced the ulcer for the first time at period < 1 month after application. The location of traumatic ulcer in buccal mucosa is 80% and lip mucosa 20%. The most common cause of traumatic ulcer is wire (56%). Ulcer with irregular frequency found in 72.7% respondents. About 43.7% respondents left the ulcer untreated, 12.7% made dental visit, and about 40% made self-treating which 63% of them used topical medicine.Keywords: traumatic ulcer, fixed orthodontic appliance.
