Prevalence of temporomandibular dysfunction in Turkish children with mixed and permanent dentition

Abstract

This study was carried out to determine the prevalence of temporomandibular joint (TMJ) dysfunction in mixed and permanent dentition and to evaluate the sex distribution in Turkish children. One hundred and eighty-two children with mixed dentition and 212 with permanent dentition were selected for the study, which used a questionnaire and clinical examination. Children with one or more signs (TMJ sounds, TMJ tenderness, muscle tenderness, restricted mouth opening) and/or symptoms (TMJ pain during mastication and mouth opening, restriction of the jaw opening and TMJ sounds) met the criterion of TMJ dysfunction. The total prevalence of signs and symptoms of TMJ dysfunction in the studied population was 68% (68% in girls and 68% in boys) in mixed dentition and 58% (61% in girls and 56% in boys) in permanent dentition. The Z-test and analysis of variance (ANOVA) were used for statistical analysis of the difference between the results. The total prevalence of signs and symptoms of TMJ dysfunction in mixed dentition was found to be higher than in permanent dentition (P < 0.05). No statistically significant difference was found in the total prevalence of TMJ dysfunction between girls and boys.

Prospective study of a group of pre-university students evaluating anxiety and depression relationships with temporomandibular disorders.

“…In this study, the frequency of 65% of TMD symptoms was similar to that found in other studies reported in literature, such as 63% (14) and 68% (15). However, other authors reported lower frequencies, varying from 3% to 50% (5,16-20).…”

Toll-like receptors in chronic pain

“…Literature indicates for example that prepubescent boys and girls display equal prevalence in the majority of chronic pain conditions. However, after the approximate age of 12 years, a female predominance is established up until menopause (characterized by gradually declining estrogen levels), where this prevalence thereafter declines (Abu-Arefeh and Russell, 1994; Bigal et al, 2007; Lipton et al, 2001; Ogura et al, 1985; Sonmez et al, 2001). Furthermore, pain sensitivity differences throughout the female menstrual cycle (Crawford et al, 2009; LeResche et al, 2003; Pamuk and Cakir, 2005) and the rodent estrous cycle (Frye et al, 1992; Giamberardino et al, 1997; Kayser et al, 1996) also indicate a role for gonadal hormones in chronic pain states, with higher levels of estrogens correlating with higher pain scores.…”

Effect of adenoidectomy / tonsillectomy on temporomandibular joint (TMJ) function and mouth opening in early period

“…Bu fizyolojik süreçler hastanın TME bölgesinde ciddi ağrı hissetmesine ve hareket kısıtlılığı ile karşılaşmasına yol açabilir 13 . Ön kesici dişler arası maksimum mesafe (ÖKDAMM) sağ-lıklı bireylerde 23-71 mm arası değişmekte ve TME kondil mobilitesinden etkilenmektedir 14 . Çalışmamız-da, adenoidektomi ve/veya tonsillektomi grubunda ameliyat sonrası ilk ÖKDAMM ortalama ölçümlerin-de düşüş görülmüştür.…”
