“…Other lesser commonly encountered complication includes dislodgement of the tooth into the maxillary sinus, maxillary tuberosity fracture, pterygoid plate fracture, and tethering of buccal fat pad. 8,11,18 The findings of our study reflected a similar picture, with broken root pieces being the most common complication (4.9%) and followed by OAC (3.5%).…”

Objective Oro-antral communication (OAC) is one of the most frequently encountered complications during third molar extraction. Various radiographic factors, like excessive maxillary sinus pneumatization, long periods of edentulism, periapical lesions, etc., have been considered high-risk factors for OAC. However, a panoramic radiograph has not proven to be accurate in predicting the chances of OAC. Through this retrospective study, we evaluated the efficacy of a CBCT in predicting the incidence of OAC after maxillary third molar extraction. Materials and Methods We conducted a retrospective study in our department, which included the patients who had undergone extraction of a maxillary third molar over five years with the presence of panoramic X-rays and/or CBCT scans prior to extraction. Primary outcomes assessed from the case files were intra-operative complications like OAC, root fracture, tuberosity fracture, pterygoid plate fracture, etc. The incidence of these complications was correlated with the presence or absence of CBCT before extraction. Results Out of 920 extracted maxillary third molar, only 148 teeth (16.1%) had a CBCT record before extraction. The most commonly encountered complication was broken inaccessible root piece/s (4.9%), followed by OAC (3.5%). An inter-group comparison showed that a significantly higher percentage of patients (p < 0.001) with CBCT records had an incidence of OAC (11.5%) as against the group of patients with no CBCT record (1.9%). Conclusion A CBCT scan prior to cases with high-risk factors for OAC can be a valuable tool in accurately predicting the chances of OAC after maxillary third molar extraction.

“…; Douglas & Wormald, ). What is more, accurate GPF localization is needed when aiming to mobilize the greater palatine artery during oroantral fistulae closure using mucoperiosteal pedicled palatal flaps (Bell, ; Piagkou et al. ) or during palatal mucosa graft harvesting for periodontal proposes (Klosek & Rungruang, ).…”

Anatomical landmarks for the localization of the greater palatine foramen – a study of 1200 head CTs, 150 dry skulls, systematic review of literature and meta‐analysis

et al. 2014

Accurate knowledge of greater palatine foramen (GPF) anatomy is necessary when performing a variety of anaesthesiological, dental or surgical procedures. The first aim of this study was to localize the GPF in relation to multiple anatomical landmarks. The second aim was to perform a systematic review of literature, and to conduct a meta-analysis on the subject of GPF position to aid clinicians in their practice. One-hundred and fifty dry, adult, human skulls and 1200 archived head computed tomography scans were assessed and measured in terms of GPF relation to other anatomical reference points. A systematic literature search was performed using the PubMed, Embase and Web of Science databases, and a meta-analysis on the subject of GPF relation to the maxillary molars was conducted. On average, in the Polish population, the GPF was positioned 15.9 AE 1.5 mm from the midline maxillary suture (MMS), 3.0 AE 1.2 mm from the alveolar ridge (AR) and 17.0 AE 1.5 mm from the posterior nasal spine (PNS); 74.7% of GPF were positioned opposite the third maxillary molar (M3). Twenty-seven studies were included in the systematic review and 23 in the meta-analysis (n = 6927 GPF). The pooled prevalence of the GPF being positioned opposite the M3 was 63.9% (95% confidence interval = 56.6-70.9%). Concluding, the GPF is most often located opposite the M3 in the majority of the world's populations. The maxillary molars are the best landmarks for locating the GPF. In edentulous patients the most useful points for approximating the position of the GPF are the AR, MMS and PNS. This study introduces an easy and repeatable classification to reference the GPF to the maxillary molars.

“…[ 14 ] Hence, the speech will not be affected after simple or complicated surgical dental extractions. [ 16 17 18 ] However, in our study, speech variations postextraction were observed among the patients, and it affected their quality-of-life postextraction. In certain studies, few patients showed a minor change in appearance.…”

“…[ 7 8 ] Certain studies depict that dental extraction in patients on an antiplatelet regimen can be performed without any concern for the safety of the patient. [ 16 17 18 ] In a study done by Savin and Ogden,[ 21 ] the results depicted that diet variations were most frequently affected after dental extraction in the range of 24%–32%. Evaluating the dietary changes revealed that the most frequent issues were the inability or struggle in mastication and the inability to enjoy the experience of eating food.…”
