Treponema Denticola and Porphyromonas Gingivalis as Bioindicator Oral Hygiene Status and Organoleptic Score in Mouth Breathing Children

Abstract

Objective: Mouth breathing is a bad habit that has several impacts on dentocraniofacial growth and development in children. It also related to anotheroral cavity condition, such as poor oral hygiene and halitosis. Halitosis is caused by an anaerobic bacteria product such as Treponema denticola andPorphyromonas gingivalis. These bacteria are Gram-negative anaerobic bacteria that play a significant role to halitosis occurrence. The objective of thisstudy is to determine the prevalence of T. denticola and P. gingivalis as bioindicator in mouth breathing children.Methods: A total number of 60 subjects had a mouth breathing test (19 subjects diagnosed as mouth breathers and 41 subjects as nose breathers).Then, the subjects were classified into halitosis and oral hygiene status category. Identification of T. denticola and P. gingivalis in supragingival plaqueand buccal mucosa subjects was used a conventional polymerase chain reaction method.Results: The correlation between Oral Hygiene Index-Simplified and organoleptic score in mouth breathers has positive correlation (r=0.001), inthe contrary, in nose breathers, it has negative correlation (r=−0.046). Meanwhile, the prevalence of T. denticola and P. gingivalis in mouth and nosebreathers has no significant differences. Moreover, the significance value of prevalence T. denticola and P. gingivalis based on clinical parametershalitosis and oral hygiene status has no differences.Conclusion: The prevalence of T. denticola and P. gingivalis cannot be used as bioindicator in mouth breathers.

Oral Hygiene Index in Children Aged 7-10 Years with Stainless Steel Crowns: Retrospective Study

“…The Oral Hygiene Index is made up of the combined Debris Index and Calculus Index, each of which is made up of 12 numerical determinations that reflect the amount of debris or calculus on the buccal and lingual surfaces of each of the three segments of each dental arch, namely the segment distal to the right cuspid, the segment distal to the left cuspid, and the segment mesial to the right and left first bicuspids [1]. Debris and calculus are analyzed in each sextant.…”
