Prevalence of Temporomandibular Pain Dysfunction Syndrome Among 20-23 Years Old Medical and Health Sciences Students in Khartoum State
There have been no previous studies on the prevalence of the
temporomandibular pain dysfunction syndrome (TMPDS) among
the Sudanese population. Although, thousands of studies were
carried on TMPDS, the etiology of this syndrome remains unclear,
creating a demand for further studies.
This study was carried out to evaluate the prevalence and
gender distribution of TMPDS symptoms and the related potential
risk factors among 20-23 years old medical and health sciences
students in Khartoum state.
The present study comprised a cross sectional study as well
as a case control study. The sample of the cross sectional study
comprised 2949 students who were selected randomly form the
3rd, 4th and 5th levels of the medical and health sciences students
in Khartoum state. All subjects completed a questionnaire
concerning the medical history, the symptoms of TMPDS, certain
parafunctional habits, and history of trauma.
The case control study included 150 patients with myofascial
pain dysfunction syndrome (MPDS) who were found to satisfy our
inclusion and exclusion criteria. The inclusion criteria of the MPDS
was a modification of that published by Gray et al in 1994. A
control group included 150 cases who were matched by age and
gender to the MPDS patients.
The clinical assessment was conducted as described by Gray et al
in 1994, Khalid et al in 2002 and Von Korff et al in 1992.
The prevalence of TMPDS symptoms was found as follows:
TMJ sound (22.3%), TM pain (17.7%), feeling of uncomfortable
bite (14.9%), jaw stiffness in the morning (3.9%) and limited
mouth opening (9.4%). The recurrent headache and tinnitus were
reported by 30.3% and 19% of the subjects respectively and were
significantly associated with TMPDS symptoms and MPDS group.
The prevalence of the parafunctional habits was as follows:
bruxism (5.9%), clenching (19.2%), gum chewing (57.7%) and
chewing on one side (39.5%). Bruxism, clenching and chewing on
one side habits were significantly associated with TMPDS
symptoms and MPDS group.
As indicated by APSQ, 44.7% of MPDS patients and 12% of
the control subjects had depression, 24.7% of MPDS patients and
7.3% of the control subjects had anxiety. At the level of
multivariate analysis, the factors that remained significantly
associated with MPDS were depression, anxiety, non working side
interferences, clenching and chewing on one side. The percentage
distribution of pain intensity and disability in MPDS patients was as
follows: low pain intensity and low disability (59.3%), high pain
intensity and low disability (34%), moderate disability (6%) and
high disability (0.7%).
Within the limitation of this study, it can be concluded that
the prevalence of the TMPDS was relatively high among the
Sudanese medical and health sciences students of this age group
however, the pain related disability was low. The etiology of MPDS
is a multi-factorial thus, regarding diagnosis and treatment of
MPDS, the tunnel vision should be avoided
Effect of partial ferrule on fracture resistance of endodontically treated teeth: A meta-analysis of in-vitro studies.
The present meta-analysis aimed to answer the following research question: In endodontically treated teeth (ETT), what is the effect of partial ferrule (PF) on fracture resistance compared to complete ferrule (CF) and/or no ferrule (NF)? PubMed, Scopus, Web of Science, and Google Scholar were searched for relevant studies published until May 20, 2022. In vitro studies that compared the effect of partial ferrule with that of complete ferrule and/or no ferrule on fracture resistance of ETT were included. The studies were assessed for risk of bias, and a meta-analysis was performed. Seventeen in vitro studies comprising 807 teeth were included. Nine studies were at a high risk of bias and eight presented a moderate risk of bias. Overall, the results showed that CF was superior to PF in increasing fracture resistance (SMD= 0.93, CI= 0.57-1.29, P< 0.0001), with no change in the effect based on the type of teeth (P< 0.001). However, the subgroup analysis found that PF 2 mm buccal, lingual, and buccal and lingual ferrule were comparable to CF (P= 0.06). Additionally, the PF group showed significantly higher fracture resistance than the NF group (SMD= 2.02, CI= 1.54-2.49, P< 0.00001). Although CF design provided the highest fracture resistance to restored ETT, PF can still be a viable option for restoring ETT in cases where CF is not feasible
