Abstract
Knowing the International Classification of Orofacial Pain helps pain specialists to differentiate types of orofacial pain. It is important to select the best treatment or intervention for the patients based on the diagnosis. As part of our study, we reviewed the article published in BMC Oral Health, titled “Clinical characteristics and associated factors of trigeminal neuralgia: Experience from Addis Ababa, Ethiopia” by Ayele et al. (Ethiopia BMC Oral Health 20(1):7, 2020). For patients suffering from Classical Trigeminal Neuralgia taking a suitable dose of Carbamazepine or Gasser Ganglion radiofrequency could be helpful. Patients complaining Trigeminal neuralgia who had a history of a dental extraction in the painful region should be categorized in other group as Complex Regional Pain Syndrome type 1, who need larger dose of carbamazepine with anticonvulsant or tricyclic agent drugs (e.g. pregabalin or doxepin) or intervention (PPG radiofrequency).
Highlights
Definitive diagnosis for facial pain is a complicated task, and requires expertise and meticulousness
Incautious description of symptoms can negatively affect scientific conversations, training of physicians and patients’ treatments. In their published article at BMC-Oral Health, Ayele et al suggested that there was a significant association between higher doses of Carbamazepine and history of tooth extraction [1]
The authors hypothesized that their study participants with a positive history of tooth extraction would require higher doses of Carbamazepine—to relieve their facial pain—compared to those with no history of tooth extraction [1-p.3]
Summary
Definitive diagnosis for facial pain is a complicated task, and requires expertise and meticulousness. The authors observed a higher proportion of dental extraction among their patients, hinting at the scale of Discussion [1] claim that they included 61 TN patients in the research study [1-p.3]; and outwardly they used International Classification of Headache Disorders 3th edition (ICHD-3) for diagnosis and symptoms [1-p.2]. This claim does not seem true for 2 reasons. According to the Beta ICHD3, Post traumatic trigeminal neuropathy (PTTN), is Taheri and Sepehrmand BMC Oral Health (2021) 21:291 categorized as TN, and inaccurate inclusion criteria reduces the effect size of the research study
