The Effect of Oral Health Knowledge, Attitude, and Practice on Periodontal Status among Dental Students

Abstract

Objectives The primary aim of the current study is to relate oral health knowledge, attitude, and oral hygiene practice with the periodontal condition of both undergraduate and postgraduate dental students. Materials and Methods Data were collected through a combination of self-reported questionnaire and clinical examination. The estimated sample size was 246. Probing depths and clinical attachment loss were measured in interproximal sites, whereas the gingival index was calculated based on Ramfjord teeth. The Centers for Disease Control and the American Academy of Periodontology classification was used for periodontal diagnosis. The subjects were divided into three groups. Group 1 was composed of undergraduate, preclinical dental students, group 2 consisted of undergraduate clinical-year dental students, whereas group 3 included postgraduate residents. Results A total of 296 dental students participated in this study. Significant differences were found among the groups in their oral health knowledge, attitude, and practice scores. Gingival disease was detected among most of the participants (99.2–100%) with significant differences between different educational levels (group 1 = 1.13, group 2 = 1.16, group 3 = 0.96, p- value = 0.001). Sixty percent of dental students were diagnosed with periodontal disease regardless of its severity. A positive correlation was established between oral health knowledge and attitude and oral hygiene practice. In addition, gingival inflammation severity and the severity of periodontal disease showed a positive correlation. Conclusions This study highlighted the need to improve the oral health knowledge, attitude, and practice of dental students. Gingival and periodontal inflammation was highly prevalent among participants.

The Role of Coconut Oil in Treating Patients Affected by Plaque-Induced Gingivitis: A Pilot Study

“…Together with the professional scaling and removal of etiological factors, proper home hygiene instructions and procedures have to be performed to maintain a healthy oral environment that would not facilitate bacterial growth. 26 That is why, it is believed that not only brushing and flossing are fundamental, but also a coadjuvant is strongly recommended in treating gingivitis. In the last decades, several alternative methods have been studied, trying to demonstrate to be effective in reducing plaque formation and aggregation, among them coconut oil pulling seemed to be one of the most promising.…”

Psychodiagnostics as a Mandatory Element of Patient Protocols in Dentistry

“…Through the interaction of these receptors, the consciousness forms a kind of emotional background, reflecting the patient’s perception of the physical condition. [ 22 23 24 25 ] Besides, all of the patient’s perceptions or experiences about their condition are reflected in the way they relate to their health. [ 26 ] In general, such patients can be divided into three groups: with a dismissive attitude, with an adequate attitude, and finally, the group with increased attention to their health.…”

Evaluation of the Changes of Salivary pH among Dental Students Depending on Their Anxiety Level

“…20 This often occurs among students especially during the exam period and cold affect the oral health and cause diseases such as periodontitis and gingivitis. 21 It was established that 38.09% of the students experience a high level of anxiety. The obtained results are slightly higher than those reported in the work of Saeed et al, where the percentage of students with a high anxiety level was 33.8%.…”
